ActiveX with C#

[Raed Sawalha]

I created ActiveX as following:


namespace BmpActiveXNET
{
public interface DesktopScreen
{
string getDesktopScree n();
}
[ClassInterface( ClassInterfaceT ype.AutoDual)]
public class BmpActiveX:Desk topScreen
{
public string getDesktopScree n()
{
//Capture the client screen
Bitmap bmp = BmpActiveXNET.C aptureScreen.Ge tDesktopImage() ;
//Get the Image Bytes
byte []BitmapBytes = GetBitmapBytes( bmp);
//Return Bytes as String
return GetBytesAsStrin g(BitmapBytes);
}
}
}

and register it using
regasm BmpActiveXNET.d ll /tlb:CompNet.dll /codebase

when try to create object from javascript
var o = new ActiveXObject(" BmpActiveXNET.B mpActiveX");

error generated (automation server can't create object )
why this happened? whats wrong with what I did?

Re: ActiveX with C#

Hi Raed,

The ProgID of the ActiveX might not correspond to the
"namespace_name .class_name" scheme.
Check out the exported type library for the real ProgID of the registered
ActiveX object.

Private Sub Form_Load()
Dim a As New BmpActiveX
a.getDesktopScr een
End Sub

but error said
RunTime Error -2147024894(8007 0002), or one of its dependencies was not found

Where are these :
GetDesktopImage , GetBitmapBytes, GetBytesAsStrin g ...methods stored? Same or
another assembly?

Re: ActiveX with C#

GetDesktopImage is in other assembly(Captur eScreen.dll) and all others in
same assembly

Re: ActiveX with C#

And this assembly is in the same directory as the client script?

Re: ActiveX with C#

no the ClientScript in folder and the assembly in other folder
Thanks for replies , I did the following steps which solved my problem:
1. Generate a key (sn -k mykey.key)
2. then link the key path in the assembly
3. register the assembly with GAC ( gacutil -i assemblypath)
4. register the assembly in registery using (regasm assemname
/tlb:assembname/codebase


then try the clientscript and it is done
