freeing the popup twice crashes applcation
In my execute block that gets called with a button click, I create a popup
menu to appear where the button was clicked. It current appears properly,
with a few items with one of them having a couple sub items. When this
that runs once then calls the destructor, it is fine. But if I execute it
twice (show the popup and click an item twice) then destruct, the
application crashes. I think it is because I'm not freeing the popup
correctly (which is declared as a private property).
procedure TPlugIn.Execute(AParameters : WideString);
var
i: Integer;
pnt: TPoint;
begin
GetCursorPos(pnt);
FPopup := TPopupMenu.Create(nil);
FPopup.OwnerDraw:=True;
FPopup.AutoHotkeys := maManual;
//SQL Upgrade
Item := TMenuItem.Create(FPopup);
Item.Caption := 'Database Install/Upgrade';
Item.OnClick := ShowItemCaption;
FPopup.Items.Add(Item);
//Language Folder
Item := TMenuItem.Create(FPopup);
Item.Caption := 'Language Folder';
Item.OnClick := ShowItemCaption;
FPopup.Items.Add(Item);
//Machines
Item := TMenuItem.Create(FPopup);
Item.Caption := 'Machines';
MachineItem := TMenuItem.Create(FPopup);
MachineItem.Caption := 'Sample Machine 1';
MachineItem.OnClick := ShowItemCaption;
Item.Add(MachineItem);
MachineItem := TMenuItem.Create(FPopup);
MachineItem.Caption := 'Sample Machine 2';
MachineItem.OnClick := ShowItemCaption;
Item.Add(MachineItem);
FPopup.Items.Add(Item);
Self.FPopup := FPopup;
FPopup.Popup(pnt.X, pnt.Y);
end;
In the ShowItemCaption procedure I just show the caption of that sender
object. I haven't coded specific events yet. If it free the popup in the
execute procedure, the popup doesn't appear anymore.
destructor TPlugIn.Destroy;
begin
inherited;
FPopup.Free;
//ShowMessage('freed');
end;

IList Property stays null even when member is instantiated
IList Property stays null even when member is instantiated
I am having trouble using an IList property which always seems to return
null, even though the member is is getting is instantiated:
private List<ModelRootEntity> _validTargets = new
List<ModelRootEntity>();
public IList<IModelRootEntity> ValidTargets
{
get
{
return _validTargets as IList<IModelRootEntity>;
}
protected internal set
{
if (value == null)
_validTargets.Clear();
else
_validTargets = value as List<ModelRootEntity>;
}
}
ModelRootEntity implements IModelRootEntity. I watched both values during
debugging, whilst the member shows a positive count, the property stays
null.
I also tried raising an exception within the property getter to throw if
the counts of _validTargets and _validTargets as List<ModelRootEntity> are
different, but it never threw.
Found question [Dictionary properties are always null despite dictionaries
being instantiated, which seems similar, however in my case this seems to
happen regardless of serialization.
Any ideas?

jQuery HTML CSS effects
jQuery HTML CSS effects
Is possible with the sole use of jQuery / HTML / CSS to animate a diagonal
transition of block element from bottom left corner to top right. So a
triangular shape fills the transition period until the block is filled?
I am after this as I have users with a browsers that do not support CSS3
transitions. Ideally this would work in both Chrome and IE8+

NumPy : array methods and functions not working
NumPy : array methods and functions not working
I have a problem regarding NumPy arrays.
I cannot get array methods like .T or functions like numpy.concatenate to
work with arrays I create:
>>> a=np.array([1,2,3])
>>> a
array([1, 2, 3])
>>> a.T
array([1, 2, 3])
>>> np.concatenate((a,a),axis=0)
array([1, 2, 3, 1, 2, 3])
>>> np.concatenate((a,a),axis=1)
array([1, 2, 3, 1, 2, 3])
>>>
However when I create an array using bult-in functions like rand
everything is fine
>>> a=np.random.rand(1,4)
>>> a.T
array([[ 0.75973189],
[ 0.23873578],
[ 0.6422108 ],
[ 0.47079987]])
>>> np.concatenate((a,a),axis=0)
array([[ 0.92191111, 0.50662157, 0.75663621, 0.65802565],
[ 0.92191111, 0.50662157, 0.75663621, 0.65802565]])
Do you think it has to do with element types (int32 vs float64) ?
I anm running python 2.7 on windows 7
Any help would be greatly appreciated.
Thanks !

flask-admin queryset analog from django-admin
flask-admin queryset analog from django-admin
I'm using SQLAlchemy ModelView
Well, I'm trying to manage per-item permissions in my admin. So, users can
change only that model instances, they created.
I can add column "author" with relation to "User" table.
After that, in django-admin typically we use
def queryset:
qs = super(...
qs = qs.filter(author = request.user)
return qs
So, how to do this in flask-admin. Mb, it's definitely another way, and
maybe there is "queryset" analog?

To make the following code run faster?
Consider the code:
where i read an input file with 6columns (0-5)
Initialize a variable historyends to 5000.
Next when the column0 value i,e job[0] < 5000 i add 5000lines of the input
file in a list(historyjobs) else the rest of the lines till the eof in
another list(targetjobs).
Next all the historyjobs list all contents in item3,item4,item5 is equal
to targetjobs first list item3,item4,item5 when this condition is
satisfied add those historyjobs all item1 to list listsub.
Next find the running mean of the items in listsub & reverse the
list,store it in list a.Check the condition if items in listsub > a*0.9
the which staisfies the condition stores the result items in list condsub.
Next reopen the inputfile & check whether column0 is equal to items in
condsub if it satisfies then add the column1 to a list condrun.
Finally open the output file & write in colum0 the second item of first
list in targetjobs i,e j,in column1 write the average of list
condrun,column2 is (j-avg)/j ,column3 is maximum item in list condrun

Add a layout dynamically, to overlapp the other layout
Add a layout dynamically, to overlapp the other layout
I'm writing a "Welcome Screen" for my application, that runs when
application launches for the first time. What I want: A transparent layout
to be overlapped on the root layout, dynamically through code. like this
image:
but when I run my app, It crashes due to NULLPOINTEREXCEPTION. even when I
didn't add the second layout
Problem 1: Why first layout doesn't show up, and app crashes?
Problem 2: How to show the second layout?
thanks in advance....

I'm writing a "Welcome Screen" for my application, that runs when
application launches for the first time. What I want: A transparent layout
to be overlapped on the root layout, dynamically through code. like this
image:
but when I run my app, It crashes due to NULLPOINTEREXCEPTION. even when I
didn't add the second layout
Problem 1: Why first layout doesn't show up, and app crashes?
Problem 2: How to show the second layout?
thanks in advance....

Assigning multiple properties to a Font
Assigning multiple properties to a Font
I have some code in which I allow the user to control the different
attributes of controls on a form, i.e. Italics, Bold, BackColor,
ForeColor.
My problem is that when the user selects Italics & Bold, I'm not sure what
the format is to do this. Here is what I have so far.
For Each ctl As Control In frm.Controls
If TypeOf (ctl) Is Button Then
ctl.Font = New Font(ctl.Font, FontStyle.Italic)
End If
Next
This is the effect I want:
ctl.Font = New Font(ctl.Font, FontStyle.Italic, FontStyle.Bold)

Replacing property dynamically based on environments in ANT scripts
Replacing property dynamically based on environments in ANT scripts
I want to develop ant script which replaces application properties with
environment specific properties. My requirement is that i will have all
environment properties in single env.properties file. During building the
application i need to replace with whatever in env.properties file. Ant
replace works well when i have property files for each environment.
Sample : env.properties
dev.AddNETWORK_USER=devUser
dev.ADDPASS=devPass
sit.AddNETWORK_USER=situser
sit.ADDPASS=sitPass
This needs be replaced in mule.properties as for DEV environment:
dev.AddNETWORK_USER=devUser
dev.ADDPASS=devPass
for SIT environment:
AddNETWORK_USER=sitUser
ADDPASS=sitPass
Thanks for the Help.

Problems integrating Maven with Eclipse Kepler
Problems integrating Maven with Eclipse Kepler
I am totally new to working with Maven in Eclipse. I am using the latest
verion of Eclipse (Kepler). According other posts, as well as Eclipse's
help page
http://help.eclipse.org/kepler/index.jsp?topic=//org.eclipse.platform.doc.user/tasks/tasks-127.htm
, I am supposed to try to install new software within Eclipse IDE.
However, when I try to Add Eclipse's recommended m2e release, Eclipse
gives me an error:
Unable to read repository at
http://download.eclipse.org/technology/m2e/releases.
download.eclipse[...]releases is not a valid repository location.
Essentially I run into the same problem no matter which approach I take
outlined on the Eclipse help page. Is there some other/better way to
integrate Maven with Eclipse? Are there steps I should have taken before
this? All I have done so far is install Eclipse. How can I successfully
get Maven running?

How to bring out proper search data for the user asp.net(c#)
How to bring out proper search data for the user asp.net(c#)
Well my scenario is like this i need to show certain apps to a user by
matching his/her country , state , Age group and gender.
For this i have a DB and an admin panel where i enter a set of apps with
fields like what country you want to target , gender you want to target ,
age group you want to target etc. [However these options can be left
blank]
Right now i have made a query that brings out a list based on all provided
parameters which makes the search very specific what should i do to solve
this problem how can i make this scenario better and show results when the
below query is empty. [Don't have much data to work with right now]
select * from App where
((@CountryId IS NULL) OR (CountryId = @CountryId)) AND
((@StateId IS NULL) OR (StateId = @StateId)) AND
((@Gender IS NULL) OR (GenderTarget = @Gender))
AND (@Age >= AppMinAge OR @Age IS NULL)
AND (@Age<= AppMaxAge OR @Age IS NULL)
Note : *OR* doesn't really help me here

Not only it distorts the visitors statistic significantly, it doesn't even

here is, what does this client do and why is it calling this page

what is heroku used for?
what is heroku used for?
I know this is really basic question, but I still have some confusion over
what exactly heroku is meant for. For example, if I create some simple
python program that says "hello world" can I use heroku for that?
I've read several tutorials as well as herokus own website and still don't
quite get it. I think the descriptions are too dense for me.
Can some explain this in incredibly simple laymans terms?

Writing gpg decrypted file to a specified outfile
Writing gpg decrypted file to a specified outfile
I attempted to decrypt an encrypted gpg file using:
gpg -d <encrypted file> --output <outfile>
and just get a message: usage: gpg [options] --decrypt [filename]
In contrast, if I use
gpg -d <encrypted file>
the file is decrypted, but it's written to a default file and displayed to
the terminal screen. The former isn't a big issue, but the latter (display
in terminal screen while decrypting) is a real nuisance. What, if
anything, can be done about it?

C++ virtual variable in inheritance class hierarchy
I have a template class hierarchy,

Now I need to do some operations depending on the value on NullPosition,
but I am having hard time since the variable are different type and
values. To be more specific NullPosition in classA identifies an invalid
array index, therefore equals -1; in classB it identifies a NULL pointer
therefore it equals 0.

How can I check if a php array's keys all have values and none are blank or unset
How can I check if a php array's keys all have values and none are blank
or unset
I create a php array on the fly like below in php, which is then
json_encoded and sent back to the ajax script that requested it.
$myarr['key_a'] = 'a';
$myarr['key_b'] = 'b';
$myarr['key_c'] = 'c';
Before I do the json_encode, since the values for this come from a
database, is there someway I can check if all values are set and none are
blank or unset without having to check each key individually?

How to display an inline ProgressBar spinner?
How to display an inline ProgressBar spinner?
I want to display a ProgressBar spinner in place of another View, while it
is loading (i.e. NOT in a dialog). To be clear, I only want the
ProgressBar to replace one View, not take over the Window or Activity.
The best solution I can think of is to place both a ProgressBar and the
actual View in the layout, with the ProgressBar visibility set to VISIBLE
and the View visibility set to GONE. After loading, I swap their
visibility.
This will work but I was hoping for a more elegant solution. Any suggestions?

Load balancing DotNetNuke with Amazon with autoscale
Load balancing DotNetNuke with Amazon with autoscale
I am new to cloud services and need somebody to help me in getting started
with my project.
I have been tasked with building a web environment for a production .Net
application that utilizes DotNetNuke as a front-end CMS.
My end goal (hopefully) is the following:
Create two always-on web servers running DotNetNuke (with the ability to
scale on the fly with autoscaling when under heavy traffic)
Create two always-on SQL servers running SQL Server (with the ability to
scale on the fly with autoscaling when under traffic)
Ideally, I'd like my servers to have static private addresses configured
as such:
Public IP -NAT-> Private IP (172.x.x.x) -> Interface1 -> [Web Cluster] ->
Interface2 -> Backend Private IP (10.x.x.x) -> [Database Cluster]
This particular application sees heavy traffic and currently our managed
provider is not really giving us what we need in terms of performance
(latency issues, stability issues, etc).
That said, I would like these resources to also be load balanced, and
continuously identical to one another. I don't have the option of using
Amazon's database services for this, nor do I have the option of using
Beanstalk.
Is this even possible? I've found some documentation online that loosely
relates to what I'm looking for, but I feel like I'm not experienced
enough with Amazon to really understand what these tutorials are talking
about.
Any help or guidance would be greatly appreciated.

Using R to reformat data from cross-tab to one-datum-per-line format
Using R to reformat data from cross-tab to one-datum-per-line format
I'm using R to pull in data through an API and merge all of it into a
single table, which I then write to a CSV file. To graph it properly in
Tableau, however, I need to prepare the data by using their reformatting
tool for Excel to get it from a cross-tablulated format to a format where
each line contains only once piece of data. For example, taking something
from the format:
ID,Gender,School,Math,English,Science
1,M,West,90,80,70
2,F,South,50,50,50
To:
ID,Gender,School,Subject,Score
1,M,West,Math,90
1,M,West,English,80
1,M,West,Science,70
2,F,South,Math,50
2,F,South,English,50
2,F,South,Science,50
Are there any existing tools in R or in an R library that would allow me
to do this, or that would provide a starting point? I am trying to
automate the preparation of data for Tableau so that I just need to run a
single script to get it formatted properly, and would like to remove the
manual Excel step if possible.

Progress 4GL queries
Progress 4GL queries
I am new to this language and having some problems understand queries.
for example:
There are 2 database tables: Warehouse, product. So each warehouse can
have multiple products and products can be stored in different warehouses.
Query:
for each warehouse,
each product:
display warehouse.name, product.prodcode.
end.
the display will like
warehousename productcode awarehouse SKA-301
so for this result, are these columns display total independent result,
eg. SKA-301 product may not in awarehouse. Or it will display the product
in awarehouse? what if product and warehouse don't have related fields?
Please help me. Thank you.

How to update database items using multiple threads within a transaction?
How to update database items using multiple threads within a transaction?
I hope you can help me
I'm writing an ASP.NET application and I have to loop on over more than
70,000 datarows within a datatable in order to update database records
(each datatable row has information to update a database record). My idea
was to break the table into 10,000 rows tables and create some async
methods to update the database (one async method per table). I need to
make sure every record on the table is updates, so everything is wrapped
into a TransacionScope block.
The problem is, when I run the Page.ExecuteRegisteredAsyncTasks() I get a
Timeout exception telling me that the max allowed time to get a connection
was finished.
My code is as follows
using (TransactionScope transaccion = new
TransactionScope(TransactionScopeOption.RequiresNew, new TimeSpan(0, 120,
0)))
{
//Validando momentos
clConsultoraCompensationPlan.asignaValoresFinales(dtConsultoraCompensationPlan,
compensation_plan, usuario,pagina);
transaccion.Complete();
}
private static void asignaValoresFinales(DataTable dtConsultorasMaster,
clCompensationPlan compensation_plan, int usuario,Page pagina)
{

I hope you can help me
I'm writing an ASP.NET application and I have to loop on over more than
70,000 datarows within a datatable in order to update database records
(each datatable row has information to update a database record). My idea
was to break the table into 10,000 rows tables and create some async
methods to update the database (one async method per table). I need to
make sure every record on the table is updates, so everything is wrapped
into a TransacionScope block.
The problem is, when I run the Page.ExecuteRegisteredAsyncTasks() I get a
Timeout exception telling me that the max allowed time to get a connection
was finished.
My code is as follows
using (TransactionScope transaccion = new
TransactionScope(TransactionScopeOption.RequiresNew, new TimeSpan(0, 120,
0)))
{
//Validando momentos
clConsultoraCompensationPlan.asignaValoresFinales(dtConsultoraCompensationPlan,
compensation_plan, usuario,pagina);
transaccion.Complete();
}
private static void asignaValoresFinales(DataTable dtConsultorasMaster,
clCompensationPlan compensation_plan, int usuario,Page pagina)
{
List<DataTable> lista_tablas = new List<DataTable>();
//Separadno la tabla en 30 tablas
foreach(IEnumerable<DataRow> renglones in
LinqExtensions.Split(dtConsultorasMaster.AsEnumerable(), 50))
{
lista_tablas.Add(renglones.CopyToDataTable());
}
foreach (DataTable dtConsultoraCompensationPlan in lista_tablas)
{
AsignaValoresFinalesAsincrono tarea = new AsignaValoresFinalesAsincrono();
PageAsyncTask tarea_asincrona = new PageAsyncTask(tarea.OnBegin,
tarea.OnEnd, tarea.OnTimeout, new
ContenedorAsignaValoresFinalesAsincrono(dtConsultoraCompensationPlan,compensation_plan,usuario),
true);
pagina.RegisterAsyncTask(tarea_asincrona);

Socket wait for read before writing
Socket wait for read before writing
Desire: I want to connect to the socket and have 'running' sent to the
client every second.
This of course is a test.
Issue: The output 'running' is only sent when the client sends data. It
seems like the loop is pausing waiting on the client to write back.
Code:
$socket = @socket_create_listen("12345");
while (true) {
$client = socket_accept($socket);
$msg = "\nHello"."\r\n".chr(0);
$length = strlen($msg);
socket_write($client, $msg,$length);
usleep(5);
while (true) {
$msg = 'running'."\r\n".chr(0);
$length = strlen($msg);
socket_write($client, $msg, $length);
sleep(1);
}
}
I am really not sure what could cause this.
Thanks JT

Django, storing HTML code in databases
Django, storing HTML code in databases
So I am currently designing a website that I am deploying on Heroku with
Django.
I want to have project pages that I load dynamically using templates
(instead of hard coding various HTML templates) and loading them
dynamically into a div on page load time. These pages are going to be
"project" pages and I am currently thinking of the best way to store them.
I do not think they will be overly similar to each other since I want
different pages to use different HTML, though the general layout will be
similar. I also want to be able to store code sections, much like stack
overflow.
I have 2 ideas on how to store the information:
1) Create a text field and let myself render the HTML tags (since its only
me the admin posting to these pages)
2) Create HTML templates and use a database to store links to the pages so
I can dynamically render a side tab to view the latest and easily archive
them.
What would be the best approach? Any other ideas are welcome as well.

Can I Replace A Deleted Key In The Registry Win XP SP3?
I deleted the key HKEY_LOCAL_MACHINE/SYSTEM/CONTROLSET001/SERVICES/TUNMP

the machine tells me it 'might be needed for bootup' or somesuch.
I was following these helpful instructions:

Now I can't even start the adapter because of the registry hole and I seem
to need it for somethings, for instance my Blaze DTV.
Can I somehow find a way to complete that uninstall?
Or Can I somehow replace this Key? This key exists in Controlset003 and 4.
Could I copy that over and have it work okay?

I'm getting the following error when I try to install an app via

When I first got this error, I thought it might be due to Apple's

my provisioning profiles.
I then deleted all the profiles from my iPhone, and from XCode, and I

Then I archived the app, uploaded to test flight, gave permission to all

The problem I now have is that when the client (OLEDB) applications access
the server to create an new customer for example their memory usage peaks
out at 1.23GB whilst performing the task. On some workstations they simply
run out out memory and the operation fails. I have loaded an earlier much
smaller copy of the database and when running that the memory usage is
less then 50MB. So memory creep seems to be related to number of records
in the database. What can I do on the client workstations to determine
what is using the memory and how to reduce the memory usage. Any advice
would be greatly appreciated. Many thanks. Arthur

server and its client XP workstations running MS SQL 2005 Native client.

Identity in Euclidean Domain
Identity in Euclidean Domain
let A be a ring that is commutative and also has a euclidean norm function
d.Then A must have an multiplicative identity.
here d is a function from nonzero elements of A to nonnegative integers
satisfying the property: for every a and nonzero b in A there exists q and
r in A such that a=bq+r and either r=0 or d(r)

Debugging C Linked List Program caught in infinite loop
Debugging C Linked List Program caught in infinite loop
So this is a very simple program to create and display a linked list. Here
I'm getting caught in the display loop, and I'm seeing infinite
'2->2->2->...' on screen.
After debugging, I can see that my program ALWAYS goes into the if
statement of insertNode() whereas it should only go there ONCE i.e. when
the linked list is initialized.
#include <stdio.h>
#include <stdlib.h>
struct node {
int data;
struct node * next;
};
struct node * head = NULL;
struct node * curr = NULL;
void insertNode(struct node * temp2) {
if (head == NULL) {
head = temp2;
head->next = NULL;
}
else {
temp2->next = head;
head = temp2;
}
}
void display() {
curr = head;
while (curr->next != NULL)
{
printf("%d->",curr->data);
curr = curr->next;
}
}
void main() {
struct node * temp = (struct node *) malloc (sizeof(struct node));
temp->data = 5;
insertNode(temp);
temp->data = 6;
insertNode(temp);
temp->data = 1;
insertNode(temp);
temp->data = 2;
insertNode(temp);
display();
}

nivo slider with sliding HTML captions
nivo slider with sliding HTML captions
I'm using nivo slider with HTML captions. Now the images slide, but the
captions just appear if the image slide. But I want the captions to be
slided with the images.
See here my nivo slider: link
I found this code, but that also slides the caption after the image has
slided. And also the direction is fixed.
I have no idea how to fix this or if this is even possible with nivo slider.
PS: I already have a working slider, buth the customer tells me that it is
not working on his computer (navigation buttons don't react). However..
It's working on all major browsers on my computer and all friends I asked.

Transforming SQL results in PHP into correct value for shopping cart to recognise
Transforming SQL results in PHP into correct value for shopping cart to
recognise
So I have quite a specific question and would appreciate if anyone is able
help at all. I'm trying to create a page that lists a users purchase
history for the past 3 months. I have simply stored the cart session data
into the table as their purchase for each transaction, which is each item
id X qty. For example, one entry may be '1,1,1,2,2,3,6,1' and another may
be '6,5,9,6,6'. I don't know how to retrieve the data from the table with
PHP in such a way that the code I have from the cart that details each of
the item ID's can recognise it. Below is the code I'm using to try and
create a value, and under that is the shopping cart page pasted in. All in
all, I would just like to be able to display all the retrieved items as a
user purchase history.
Thank you very very much.

$hist = "SELECT ORDITEMS FROM cust_orderc WHERE ORDDATE >

What is the when.js equivalent of Q.js's "done()"?
What is the when.js equivalent of Q.js's "done()"?
In addition to then(), Q.js also has a done(). done() is usually called at
the end of a promise chain, like this:
promise .then(callback) .then(callback) .done(callback);
This will catch any rejections that were not handled by the previous
then()s, and it will handle any exceptions raised in then()'s callbacks.
Is there something similar in when.js? How do you handle exceptions raised
in callbacks? And what if you never register a rejection handler?

JTable in JScrollPane, how to set background?
I am using a JScrollPane to wrap a JTable. Depending on the configuration,
there is some space that is not occupied by the table. It is drawn gray
(it looks like it is transparent and you can just see the component in the
back). How can I set this area to be a certain color?

I am using a JScrollPane to wrap a JTable. Depending on the configuration,
there is some space that is not occupied by the table. It is drawn gray
(it looks like it is transparent and you can just see the component in the
back). How can I set this area to be a certain color?
Here is a SSCCE to illustrate.

Struts 1 ExceptionHandler doesn't work for Filter
Struts 1 ExceptionHandler doesn't work for Filter
I want to define a global exception handler for the Struts 1.x web
application. I do it in the struts-config.xml like this:
<global-exceptions>
<exception
key="some.key"
type="com.example.DatabaseException"
handler="com.example.DatabaseExceptionHandler"
path="error.jsp" />
</global-exceptions>
The exception occurs in AuthenticationFilter, not in Struts Action. I
think this is the reason why DatabaseExceptionHandler is never called. But
how to overcome this limitation? I want to be able to catch all the
exceptions, not only those, raised by Struts Actions.

Calling javascript within Chrome from C#
Calling javascript within Chrome from C#
We have a .net (C#) application that launches an accompanying web page in
an external browser window, and then needs to communicate with that page
via javascript.
We have successfully done this with Internet Explorer, using
mshtml.HTMLDocument. We iterate over the ShellWindows to find the open
Internet Explorer window, and then can do something like the following:
mshtml.HTMLDocument doc = iExplorer.Document;
mshtml.IHTMLWindow2 win = doc.parentWindow as mshtml.IHTMLWindow2;
win.execScript("myJavaScriptFunction('arg1','arg2')", "javascript");
Is there an equivalent way to do this with Chrome? We can find the Chrome
window, but is there an equivalent API we can call into to execute
javascript on the desired page?
