Im wondering how you are calling C/C++ functions from VB .Net directly
how have you included the files in the project?

you should convert it to a DLL file and then use it.

Hi Shashi...thanks for the reply

You are right, all of my C/C++ functions to be called inside my VB.NET are imported as DLL.

something like :
(C/C++ Side)
declaration:
MY_IMPORT_DLL unsigned int count_me_in();

definition:
unsigned int count_me_in(){
return let_me_in;
}

(VB Side)
Declare Function CountMeIn Lib "MyEventManager" Alias _count_me_in@0 As Integer()


That way, you can simply call those C/C++ Function inside VB. but i dont know how to import C# function since it doesnt have function declaration where you can define as imported dll.

Any idea?

Create a new project of type Class library and choose c# as the language
copy those c# files in it, and compile it.
The DLL will be creating in the bin\Debug or bin\Release depends on what you choose.

Once you are back in the VB .Net project, import the DLL file u created from the steps above

Okay, thank you very much, I'll try this tomorrow and I will let you know the result.
