    Well first I would do this on a dialog. Have a static text called Name: followed by a edit control with a member variable called m_Name. Then on the next line have another static text called First Number: followed by another edit control with a member variable called m_First. (Do the same for Second, and Total).

    Then have a button labeld Get Total. And on the OnGetTotal() fuction declare 3 variables of type int for your First, Second and Total and one variable of type CString Name.

    Use m_First.GetWindowText(First);
    Use the same for Second and Name.

    Then Total = First + Second.

    <edit:>
    m_Total.SetWindowText("Hello "+Name+" your total is "+Total);
    </edit>

    And call UpdateData(FALSE);

    Smile Step by step..

    Hi ski6ski,
    Actually I do program in C. VC++ is very new to me. So, can you help me little more.. Just tell me step by step from
    Starting VC++
    Click File from Menu
    Select New
    Select Win32 Application, put a project name, Press OK
    .. .. ... ..
    .. .. ... ..

    This is the first time, I'm sure next time I will do better.

    You are asking a lot there zahid.

    Try a search on 'callback', 'winmain'

    Look for links to Petzold's web site. He wrote the "Programming Windows" books, one of the best learning guides for WIN32 API programming.

    In this thread...

    http://www.cprogramming.com/cboard/s...&threadid=6452

    ... towards the end, I gave this guy a step by step walk through to get his code to link, have a look at it. The message start "I did this, try the same...". Of course, if you want your own application, you can't use his source and header, but the basic steps are there for creating a Windows program.

    Are you sure you want to write a windows program yet. A "Hello World" is normally done in a console.

    Sorry I was using AppWizard. If you want to do it the hard way (code everything) then you will have to do it the way that Adrian or novacain suggested.

    Hello adrian,
    I have tried your code, I compiled it, found no error, but it is not displaying anything.

    Well, as I said, if you want your program to something specific, you'll have to code that up. Looking at his code, I would agree, it doesn't look like it is doing anything, he simply wanted a step by step guide to building an app with VC++, that is what you asked for!

    Yeah.. but I wanted
    Enter your name: xyz
    Enter 1st number : 10
    Enter 2nd Number: 23

    Hello XYZ, Sum of those numbers is: 33

    This minimum functionality. Anyway.. I guess I have to study little more. Though I have tried, may be I have to try more to find the starting point.

    Well, as I said before...

    >>>
    Are you sure you want to write a windows program yet. A "Hello World" is normally done in a console.
    <<<

    ... I do not believe you need to write a Windows program to do this. As you have seen from the other guys code, even the simplest Windows program involves a lot before it actually does anything.

    To do what you want in a console would take probably less than 20 lines of code.

    adrianxw has given you the window. If you MUST have a non console then ....

    You need controls to get the input / display the output.

    Look at CreateWindow()
    Remember to cast the HMENU as the ID of the control ie
    #define IDC_USERNAME 10001 //unique int ID code
    then in the CreateWindow use (HMENU)IDC_USERNAME

    Capture msg's to these controls in the callback with another switch for WM_COMMAND

    ie
    Code:
    case WM_COMMAND:
    idControl = GET_WM_COMMAND_ID( wParam, lParam) ;
    switch(idControl)
    {
         case IDC_USERNAME:
         //do your validation here / capture input here
         break;
    That is the next step.

    I don't know am I finding windows programming difficult? I guess I'm missing proper guide line.

    Can anyone suggest me the easiest reknown book for windows programming?
