    Simple Windows GUI Application " The system cannot find the file specified"

    I'm using DevC++

    And I get this error:
    The system cannot find the file specified

    even though windows.h does exist, and I'm using Windows XP SP2


    Heres my code:
    Code:
    #include <windows.h>
    
    LRESULT CALLBACK WndProc ( HWND, UINT, WPARAM, LPARAM );
    
    static char sClassName[] = "MyClass";
    static HINSTANCE zhInstance = NULL;
    
    int WINAPI WinMain ( HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nCmdShow ) {
        WNDCLASSEX WndClass;
        HWND hwnd;
        MSG Msg;
        
        zhInstance = hInstance;
        
        WndClass.cbSize = sizeof(WNDCLASSEX);
        WndClass.style = NULL;
        WndClass.lpfnWndProc = WndProc;
        WndClass.cbClsExtra = 0;
        WndClass.cbWndExtra = 0;
        WndClass.hInstance = zhInstance;
        WndClass.hIcon = LoadIcon(NULL, IDI_APPLICATION);
        WndClass.hCursor = LoadCursor(NULL, IDC_ARROW);
        WndClass.hbrBackground = (HBRUSH) (COLOR_WINDOW+1);
        WndClass.lpszMenuName = NULL;
        WndClass.lpszClassName = sClassName;
        WndClass.hIconSm = LoadIcon(NULL, IDI_APPLICATION);
        
        
        if (!RegisterClassEx(&WndClass)) {
                                         MessageBox( 0,"Error registering Class!","Error!",MB_ICONSTOP | MB_OK );
                                         return 0;
                                         }
                                         
                                         hwnd = CreateWindowEx( WS_EX_STATICEDGE, sClassName, "my first gui! in win32 :P", WS_OVERLAPPED_WINDOW, CW_USEDEFAULT,
                                         CW_USEDEFAULT, 320, 240, NULL, NULL, zhInstance, NULL
                                         
                                          );
                                          
                                          if (hwnd == NULL) {

    Where is windows.h located, and where is Dev-C++ looking for include files? There should be a setting for your project, as well as a global setting.

    *should be in windows programming*

    Open up Dev, create a new project, choose win32 app. c++ lang (default). Give your project a name and choose to save all files inside of one directory (folder) including the main file you wish to compile. Doing the above will auto-generate a simple window. From that point, goto the project window, add your original main file and del the auto generated one. Save project, compile -

    That is with Visual Studio, not Dev-C++.

    No, you can.
    There's just no pre-defined templates.

    Hu? I gave instructions for DevC++. Doing the above creates a simple window, a monkey could do it.

    Really? That sounded a lot like VS.
    I don't think I remember anything such, but whatever.

    I've never used VS; I'm a little surprised that the steps are so similar.
