    Question Making scripts run in a window...

    OK, I know a small bit about the basics of C/C++ programming... however, I can only get my scripts to run in an MSDOS prompt *cringe* never in a window. I'm sure the problem is I just can't get the scripts to run... any idea if that's my problem or not?? Please help!!!

    I'm sure that you're in console mode and not Win32. Writing and running Windows programs is much different than console programs. The hello world program for example:

    Code:
    #include <iostream>
    
    int main ( void )
    {
      std::cout<<"Hello, World!\n";
      return 0;
    }
    It's very simple, but when you want to create a window and place the same text in it you're looking at quite a bit more code:
    Code:
    #include <windows.h>
    
    const char g_szClassName[] = "window one";
    
    LRESULT CALLBACK WndProc(HWND hwnd, UINT msg, WPARAM wParam, LPARAM lParam)
    {
        HDC         hdc;
        PAINTSTRUCT ps;
        RECT        rect;
        switch(msg)
        {
        case WM_PAINT:
            hdc = BeginPaint ( hwnd, &ps );
            GetClientRect ( hwnd, &rect );
            DrawText ( hdc, TEXT ( "Hello, World!" ), -1, &rect, DT_SINGLELINE );
            EndPaint ( hwnd, &ps );
            break;
        case WM_CLOSE:
            DestroyWindow(hwnd);
            break;
        case WM_DESTROY:
            PostQuitMessage(0);
            break;
        default:
            return DefWindowProc(hwnd, msg, wParam, lParam);
        }
        return 0;
    }
    
    int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance,
        LPSTR lpCmdLine, int nCmdShow)
    {
        WNDCLASSEX wc;
        HWND hwnd;
        MSG Msg;
    
        wc.cbSize        = sizeof(WNDCLASSEX);
        wc.style         = 0;
        wc.lpfnWndProc   = WndProc;
        wc.cbClsExtra    = 0;
        wc.cbWndExtra    = 0;
        wc.hInstance     = hInstance;
        wc.hIcon         = LoadIcon(NULL, IDI_APPLICATION);
        wc.hCursor       = LoadCursor(NULL, IDC_ARROW);
        wc.hbrBackground = (HBRUSH)(COLOR_WINDOW+1);
        wc.lpszMenuName  = NULL;
        wc.lpszClassName = g_szClassName;
        wc.hIconSm       = LoadIcon(NULL, IDI_APPLICATION);
    
        if(!RegisterClassEx(&wc))
        {
            MessageBox(NULL, "Window Registration Failed!", "Error!",
                MB_ICONEXCLAMATION | MB_OK);
            return 0;
        }
    
        hwnd = CreateWindowEx(
            WS_EX_CLIENTEDGE,
            g_szClassName,
            "Some Title",
            WS_OVERLAPPEDWINDOW,
            CW_USEDEFAULT, CW_USEDEFAULT, 240, 120,
            NULL, NULL, hInstance, NULL);
    
        if(hwnd == NULL)
        {
            MessageBox(NULL, "Window Creation Failed!", "Error!",
                MB_ICONEXCLAMATION | MB_OK);
            return 0;
        }
    
        ShowWindow(hwnd, nCmdShow);
        UpdateWindow(hwnd);
    
        while(GetMessage(&Msg, NULL, 0, 0) > 0)
        {
            TranslateMessage(&Msg);
            DispatchMessage(&Msg);
        }
        return Msg.wParam;
    }
