Hi all!

Please help me.

If I created a simple Managed C++ DLL and use this dll in VB >NET CF it
works fine.
But if I make managed code as a wrapper to the unmanaged code it fails.

So I was tring to make Managed Code as a wrapper to unmanaged code (in eVC
4.0). and using Managed DLL in vb .NET .
It links with out any error.
But as soon as it encounter eVC call it through exception as
System.TypeLoadException.

So my problem is "How do I link static eVC 4.0 (.LIB) to VC .NET managed
DLL. So that using same DLL I can create VB .NET CF application"

If any body help me out for same I will be helpfull for me.

Regards,

code inside eVC 4.0
