    Code:
    #include <windows.h>
    #include <stdio.h>
    #include <tchar.h>
    
    int _tmain()
    {
    	_tprintf(GetCommandLine());
    	return 0;
    }
    Code:
    D:\Temp\80>cl 80.cpp /D"UNICODE" /D"_UNICODE"
    Microsoft (R) 32-bit C/C++ Optimizing Compiler Version 16.00.40219.01 for 80x86

    80.cpp

    /out:80.exe
    80.obj

    Re: How to read sentence from Command line with MFC?

    Thank you for answer. I use this code in VC

    int _tmain()
    {
    system("D:");
    _tprintf(GetCommandLine());

    getch();
    return 0;
    }

    but when I click run button it show "C:\Users\MAX\Documents\Visual Studio 2010\Projects\TestCmd\Debug\TestCmd.exe"

    I read CCommandineInfo the function ParseCommandLine can send parameter from command to MFC, But I want to know when my console process success and ask for send Y/N to command. If MFC can know when it ask Y/N ,then I can send char to process next command.

    And what command line parameters (exactly!) did you pass in?

    And what did you expect? This is exactly the command line your process has been run with. Do you have any idea what command line is? I wonder what sense that system("D:"); makes for you?

    I read CCommandineInfo the function ParseCommandLine can send parameter from command to MFC, But I want to know when my console process success and ask for send Y/N to command. If MFC can know when it ask Y/N ,then I can send char to process next command.
    You're trying to do something you have no idea about. You cannot program Windows without knowing how the very basic OS mechanisms work.

    When program exits it always provides exit code specific to the circumstances of termination. By the code value any outer process can tell if the exit was successful or not, and typically 0 means success (a UNIX/POSIX legacy). But the part about MFC knowing something and sending another something sounds totally gibberish. This is what you have to explain, if you want to be really helped.
