I follow the sample code from MSDN as shown below.

h = CreateFileMapping(-1,pNull,PAGE_READWRITE,0, 65535,"MyShare")

The problem I am having is that I can't find where the constant pNull and PAGE_READWRITE are defined. I tried to replace pNull with vbNull, Null, 0, and 0& and I get type mismatch error. How can I create a handle by using CreateFileMapping.  Please help

Better to use:

    #define STRICT
    #define WIN32_LEAN_AND_MEAN
    #include <windows.h>
