I’m struggling with a thread that should update a TreeView. I’ve started to use the Control.Invoke method when for e.g. adding nodes and so on.
I now wonder how I “Invoke” a property.
(I got the “Cross-thread exeption…” when I try to set the TreeView.ImageIndex property)

Either make an accessor method for the property or use the propertyinfo's get's methodinfo to construct a delegate to pass to Control.Invoke 
|
|
|
|
|
Do you have any sample code on how to do that?

Hi all,
I am not too sure where to post my question, so I'll just put it here and hope that somebody will help me. Honestly, I've reached a deadend after searching ALOT. I'll greatly appreciate any help or indication.
The problem:
In Internet Explorer you can right-click on a page and hit "Export to Microsoft Excel". This command is set in the registry (HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\MenuExt\Export to Microsoft Excel) to call Excel with "EXCEL.EXE/3000".
The purpose:
I would like to develop a executable with simular functionality: the ability to be called from the internet explorer.
The question:
What is the technology that excel is using? Is it a COM object implementing an interface? How do I do that in .NET? And what on earth is that "/3000" parameter?!?
I've been looking for an answer for quite some time now. Please help.
Rgds,
G.

Due to the limitation placed on scripting languages due to security I do not believe that would be possible unless you wrapped the IE Browser in your own code, created an ActiveX control, or processed on the server.
Just my thoughts

Hi Christopher,
Thank you for sharing your thoughts. The main thing that really puzzles me is how it's possible to have a standard executable like Excel.exe being called from IE and work just like a script.
I'll follow your lead and take a closer look into ActiveX control, since I am not very familiar with those and perhaps there is something there.
Rgds,
D.

I have a solution with a managed C++ project, and a C# project which references the C++ project.
My C++ project contains the following:
struct AAA { ... };
typedef public enum BBB { ... };
public delegate void CallbackDelegate(AAA * a, BBB b);
class SomeClass
{
...
static void RegisterCallback(CallbackDelegate^ callback);
...
}My C# project is supposed to use RegisterCallback().
I can't use the CallbackDelegate in my C# project though, because it contains a pointer.
So I've declared the following in C# hoping that .NET would do the conversions for me  :
[StructLayout(LayoutKind.Sequential)]
public struct AAA { ... }
public enum BBB: int { ... }
public delegate void CallbackDelegate(AAA a, BBB b);However, now I can't send my CallbackDelegate as a parameter to RegisterCallback() because it's not the same signature.
I'm new to all of this C++.NET s**t, so I don't really know how to use it in C#.
Could anyone point me in the right direction?
Thanks in advance,
Shy.

Couldn't you just create an unsafe delegate in C#?

Hi I just wanted to know the proper way of updating a DataRow.
If I have a DataTable say locDTable which already has rows populated through
Iterate<br />
{<br />
DataRow locDRow = locDTable.NewRow();<br />
locDTable.Rows.Add(locDRow);<br />
}
How do I access (and modify a particular column entry for a particular row?
The way I would do it something like:
locDTable.Rows[rowIndex][colIndex] = newValue;
Is this the proper way?
Thank you in advance!

Hi
Maybe, instead of access to the column by an index you can use strings constants to access to columns. It seems more elegant and if you change the structure of the table the acces to the previous column doesn't change.
To access to a particular row the only way is by an index.

I agree 100% with the constants approach for column names, we do that all the time here and has paid of on numerous occasions. We also do it for the table names.
It decouples you from Database especially for column name changes (just change constant literal) as well as makes the code much more readable.
