win32 console application using MFC

Hi,
i m new to vc++. I have two different applications. once is MFC application and the other is win32 console application. i want to get the data from MFC application to win32 console application. can anyone explain me how to integrate an MFC application with win32 console application.

Thanks in Advance

 

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:

class CAboutDlg : public CDialog
{
public:
	CAboutDlg();

// Dialog Data
	//{{AFX_DATA(CAboutDlg)
	enum { IDD = IDD_ABOUTBOX };
	//}}AFX_DATA

	// ClassWizard generated virtual function overrides
	//{{AFX_VIRTUAL(CAboutDlg)
	protected:
	virtual void DoDataExchange(CDataExchange* pDX);    // DDX/DDV support
	//}}AFX_VIRTUAL

// Implementation
protected:
	//{{AFX_MSG(CAboutDlg)
	//}}AFX_MSG
	DECLARE_MESSAGE_MAP()
};

CAboutDlg::CAboutDlg() : CDialog(CAboutDlg::IDD)
{
	//{{AFX_DATA_INIT(CAboutDlg)
	//}}AFX_DATA_INIT
}

void CAboutDlg::DoDataExchange(CDataExchange* pDX)
{
	CDialog::DoDataExchange(pDX);
	//{{AFX_DATA_MAP(CAboutDlg)
	//}}AFX_DATA_MAP
}

BEGIN_MESSAGE_MAP(CAboutDlg, CDialog)
	//{{AFX_MSG_MAP(CAboutDlg)
		// No message handlers
	//}}AFX_MSG_MAP
END_MESSAGE_MAP()

Console.exe is a win32 console application. i m able to create a process and it is successfully running but i dont know how to send the data to the console application.

Please help me. i m deadly need of this.

Thanks in Advance.
