Tried the timer, it simply doesn't trigger. Nothing hasppens. It is incredible.

You can't display a form from a threadpool thread (which I think OnReceive is). This[^] article tells you why it's a bad idea to do any UI manipulation from a non UI thread. For your problem, I'd suggest calling Invoke like this
delegate void FormShowDelegate(Form f);
public void OnReceive(IAsyncResult ar)
{
TO[num].Invoke(new FormShowDelegate(ShowForm), new object[]{TO[num]});
}
private void ShowForm(Form f)
{
f.Show();
}
This of course, assumes that you populated the TO[num] array from the UI thread..

Thank you verry much. I found out that the function runs in a new thread (or something like that) and to call a function in the main thread I would use invoke a few hours ago. Still, thank you very much, I'm so happy the program works now
Cheers

I'm a bit of a tyro when it comes to .net, so I'm sorry if this question sounds very basic.
I want to create an EXE, which will offer a File Open dialog box. The user has to select a DLL which contains a class that implements a specific interface. I want to be able to create an instance of the class contained in the DLL and call some methods that it exposes, passing certain parameters and receiving return values.
How can I do this? I'd be grateful if anybody can kick me in the right direction.
Cheers,

Thanks, Kodanda Pani.
I don't know VB, but I should be able to decipher it.
Thanks very much.

Reflection is the way to go. You can use Assembly.Load[^] or one of its variations to get an Assembly object, then use the GetExportedTypes[^] method on that Assembly object to retrieve types in that assembly. You can then iterate over the types and use FindInterfaces[^] to check if that type implements the interface you want. Activator.CreateInstance[^] creates instances given the type and you should find it simple from there on.
Remember though, the assembly gets loaded in your AppDomain, so it won't get unloaded till your app (or your AppDomain) shuts down. So if some other process tries to write to that assembly, it will fail.

Thanks, Senthil. I'll look into your links.
Would you be interested in writing an article with me, on something that uses this? If you're interested, I'll explain what it's about.

Hey there,
Thanks for that code. Is there way of specifying which file(s) to include in the new email as attachments?
|
|
|
|
|
I don't know, but you can use third party component like DotNetOpenMail[^]
.Using "mailto:" you can specify subject ,body - but not file .

Hi howzit?
Does anyone know how to add annotations to an EXISTING PDF programmatically? I have been fiddling with iTextSharp from SourceForge.net but it only allows you to create new blank PDF's and then add annotations.
Any help would be greatly appreciated!

Hello,
I have some experience in openGL. I plan to deploy in C#. But is there any way to use it in C#? Specifically I want to have a nopenGL view control on my C# form without loosing the features of C# form. I found CsGL.BaseCode but it says I should have CsGL.BaseCode.dll. But I do not have it. I have CsGL bins CsGL.dll and CsGL.native.dll but not that. Is any one can send me an example related to my problem?
I will be so glad to hear for your feedbacks.

The Tao[^] framework supports OpenGL. It's officially supported by the Mono[^] project and it's supposed to compile under Visual Studio .NET too. It might be what you're looking for.
I have no experience with it. So, fingers crossed.
Here's some more info[^] on it.

You mean you want to override the standard Windows logon / station locked dialogs?
If that is what your looking for you'll need to build your own GINA[^] library, from what I can gather it isn't that difficult to do but your going to need to resort to good old fashioned C++ or something as you'll need to create a standard Windows DLL, something you can't do in C# AFAIK.
A better explaination of what GINA does and how you can to customize it can be found in this MSDN article[^].
