call C++ ATL COM from C# SSIS

Hi All,

Is it possible to call methods of C++ COM ATL component from C# SSIS component?

I did try to call methods of C++ COM ATL component and C# library inside my SSIS but without success :-(

Sure, but you have to build the interop assembly with tlbimp.exe.

Hello Kirk,

I imported the tlb as described in the articles, but still i can't call method from my COM component :-(

There is a button in the GUI of my SSIS; here is code snippet:

MyComClass c = new MyCOMClass();

c.ShowMessageBox();

c = null;

But when I press the button the entire form disappears.

I tried to show a message box too:

System.Windows.Forms.MessageBox.Show( "HELLO" );

The form disappears too.

I get lost :-( Please, help!

Thanks!
