Hi, I want to call a function int* TestCall(int ref1,int
&ref2,int n) in <MyDll.dll> file.That was written in VC++6.0. How can i
call this function in VB.
Please help me!
       Thanks!

Hai,
Add a reference to the DLL file by Right Clicking the project name in
the solution explorer. Once the reference is set, you should be able to
call the function TestCall..You might have to even register the DLL
file using RegSvr32.exe from .NET command prompt..

Hope it helps.

Only if its a NON MFC C++ DLL & normally wouldn't need to register it

Hi ,Peter
  My proplem is not how to call Dll function in VB, my strong problem
is how to declare pointer in VB6 that is returned fron function.
  Please help me,thanks

Unfortunately, there are several choices how this could be translated:
1) if a single pointer is returned, you could return an 'IntPtr'
2) if the pointer points to multiple integers, declare the function as
returning 'integer array'.
Can you show us how it's used in existing C++ code?
Good luck!
