    There are various forms of interprocess communication available in Win32, all of it is available for console programs; you just have to #include <windows.h> and any other relevant headers, then you can call the functions. There are DDE, OLE, messaging (Send/PostMessage), pipes and probably others too.

    This of course assumes you have the source to each program and can modify them accordingly. If not then it's a lot harder; you can use a technique called "screen scraping" where you look at what the application displays and work out what data underlies that information.

    Hi xpi0t0s,
    Thanks for your reply.

    How to link Win32 console application with MFC applications (both are two different executables). if you have any example code for this please post.

    Thanks in Advance

    Do you have the source code for both programs?

    Please find the code below
    Code:

    	virtual void DoDataExchange(CDataExchange* pDX);    // DDX/DDV support
    	//}}AFX_VIRTUAL
    
    // Implementation
    protected:
