Program Is Not Running In Code Blocks.But It Should!
« on: March 04, 2013, 03:31:47 pm »
This following program is not compiling in code::blocks

Code
#include <windows.h>

LRESULT CALLBACK WindowFunc(HWND, UINT, WPARAM, LPARAM);

char szWinName[] = "MyWin"; //window clss name

int WINAPI WinMain(HINSTANCE hThisInst, HINSTANCE hPrevInts, LPSTR lpszArgs, int nWinMode){

    HWND hwnd;
    MSG msg;
    WNDCLASSEX wcl;

    /*define window clss*/
    wcl.cbSize = sizeof(WNDCLASSEX); //size of WNDCLASSEX
    wcl.hInstance = hThisInst; //Handle to this instance
    wcl.lpszClassName = szWinName; //window class name
    wcl.lpfnWndProc = WindowFunc; //window function
    wcl.style = 0; //default style
    wcl.hIcon = LoadIcon(NULL, IDI_APPLICATION); //icon style
    wcl.hIconSm = LoadIcon(NULL, IDI_WINLOGO); //small icon style
    wcl.hCursor = LoadCursor(NULL, IDC_ARROW); //Cursor style
    wcl.lpszMenuName = NULL; //as no menu
    wcl.cbClsExtra = 0; //as no extra
    wcl.cbWndExtra = 0; //information needed
    wcl.hbrBackground = (HBRUSH) GetStockObject(WHITE_BRUSH); //Window Background: White
    if(!RegisterClassEx(&wcl)) return 0;

    /*Now a window class has been registered, a window can be created*/
    hwnd = CreateWindow(
        szWinName, //name of window class as prmtr
        "Window Skeleton", //Title
        WS_OVERLAPPEDWINDOW, // Window Style: Normal
        CW_USEDEFAULT, // X coordinate: Let Window Choose
        CW_USEDEFAULT, // Y coordinate: Let Window Choose
        CW_USEDEFAULT, // Width: Let Window Choose
        CW_USEDEFAULT, // Height: Let Window Choose
        HWND_DESKTOP, // No parent window
        NULL, // As No Menu
        hThisInst, // Handle to this Instance of the program
        NULL // No Additional Arguments
    );

    /*Display The Window*/
    ShowWindow(hwnd, nWinMode);
    UpdateWindow(hwnd);

    /*Creat The Message Loop*/
    while(GetMessage(&msg, NULL, 0, 0)){
        TranslateMessage(&msg); // Translate Keyboard Message
        DispatchMessage(&msg); // Return Control To Window
    }
    return msg.wParam;
}

/*This Function Called By Window And Is Passed Message from queue*/
LRESULT CALLBACK WindowFunc(HWND hwnd, UINT message, WPARAM wParam, LPARAM lParam){
    switch(message){
        case WM_DESTROY: // Terminate the program
            PostQuitMessage(0);
            break;
        default:
            return DefWindowProc(hwnd, message, wParam, lParam); //Let window process message
    }
    return 0;
}

It gives following error.
Build Log:

Standard answer you get: http://wiki.codeblocks.org/index.php?title=FAQ-Compiling_%28errors%29#Q:_How_do_I_troubleshoot_a_compiler_problem.3F

And please read the rules of the forum, you're violating it...
(most of the time I ignore long posts)

Do not only read, but also respect them.

The error is compiler/linker related but not Code::Blocks related, that 's one violation.
You also did not search the web for a solution (obviously), because the correct answer is easy to find.
