hi,
I have the following scenario:
1) a VB application for GUI
2) a C++ DLL to provide callbacks for the VB application
this DLL needs to call functions from a static library.

can this be achieved? I got core dump at the static library functions.

thanks
andrea

Yes, VB can call a DLL (regardless of whether it was written in C++ or not). You specify a DLL by declaring a function referencing the DLL:

Private Declare Function myDLLFunction Lib "mydll.dll" Alias "myDLLFunction" (ByVal lpszArg1 As String, ByVal bArg2 As Long) As Long



A DLL can be statically linked to run-time libraries.  Post your code that core dumps, I suspect your doing something wrong.

hi jhance,
i declared a new project of Win32 DLL type and in the project, i include the static library, mylib.lib.
inside one of functions in the DLL project, i called the functions in the lib, e.g. mylib->OnStart(....)

so when the application runs, it core dumps at mylib->OnStart.

a colleague suggests that I do the following:
1) create a normal c++ program (myprog) that links with mylib.lib
2) from VB, send interprocess msgs to myprog
3) from myprog, call the functions in mylib.lib to handle these msgs

pls advise.
