Beginner can't create window!?

Hi,
I am new to C++, and I would like to use CreateWindow/Ex to display a normal window. Can somebody show me how to do it, please?

PHP Code:

---

BOOL InitInstance(HANDLE hInstance, int nCmdShow)
{
    HWND hWnd;
    DWORD dwFlags = WS_OVERLAPPED | WS_CAPTION | WS_MINIMIZEBOX | WS_SYSMENU;

    hWnd = CreateWindow(szClass, "Tutorial", dwFlags, 
                        200, 300, 300, 100, NULL, NULL, (HINSTANCE)hInstance, NULL);

    if(!hWnd)
        return FALSE;

    return TRUE;
}

Technocrat -- it's now HINSTANCE rather than HANDLE for the instance handle :)

And Jhd -- are you new to C++ or Windows programming with C++?

http://www.parksie.net/Raw.zip (change LONG_PTR to LRESULT if you have any problems)

You know I dont know why it is that way in that program I took that snipit from. Thats strange :confused:

Code:

1. open visual c++
2. File > New
3. Click Projects tab
4. click Win32 Application and give it a name
5. click finish
6. click the File View Tab on TreeView
7. go to File > New
8. in the first tab Click C++ Source File and name it
9. Copy and paste the code in the new file
10. right click the Header folder and add Windows.h
11. click execute

#include <windows.h>
LRESULT CALLBACK WindowFunc(HWND, UINT, WPARAM, LPARAM);
char szWinNamw[] = "MyWin";
int WINAPI WinMain(HINSTANCE hThisInst, HINSTANCE hPrevInst,
                                LPSTR kposzArgs, int nWinMode)


    {
            HWND hwnd;
            MSG msg;
            WNDCLASSEX wcl;
            wcl.cbSize = sizeof(WNDCLASSEX);
            wcl.hInstance = hThisInst;
            wcl.lpszClassName = "My Window";
            wcl.lpfnWndProc = WindowFunc;
            wcl.style = 0;
            wcl.hIcon = LoadIcon(NULL, IDI_APPLICATION);
            wcl.hIconSm = LoadIcon(NULL, IDI_WINLOGO);
            wcl.hCursor = LoadCursor(NULL, IDC_ARROW);
            wcl.lpszMenuName = NULL;
            wcl.cbClsExtra = 0;
            wcl.cbWndExtra = 0;
            wcl.hbrBackground = (HBRUSH) GetStockObject(WHITE_BRUSH);
            if(!RegisterClassEx(&wcl)) return 0;
            hwnd = CreateWindow(
                    "My Window",
                    "Skeleton Window",
                    WS_OVERLAPPEDWINDOW,
                    CW_USEDEFAULT,
                    CW_USEDEFAULT,
                    CW_USEDEFAULT,
                    CW_USEDEFAULT,
                    HWND_DESKTOP,
                    NULL,
                    hThisInst,
                    NULL
                    );
            ShowWindow(hwnd, nWinMode);
            UpdateWindow(hwnd);
            while(GetMessage(&msg, NULL, 0, 0))


                {
                        TranslateMessage(&msg);
                        DispatchMessage(&msg);
                }
                return msg.wParam;
    }
    LRESULT CALLBACK WindowFunc(HWND hwnd, UINT message,
                                                            WPARAM wParam, LPARAM lParam)


        {


                    switch(message)        {
                    case WM_DESTROY:
                            PostQuitMessage(0);
                            break;
                    default:
                            return DefWindowProc(hwnd, message, wParam, lParam);
                    }
                    return 0;
        }

Don't add windows.h to your project...that'll confuse the compiler :eek:

Technocrat -- it used to be HANDLE for everything, until they started differentiating the handle types.

I pulled it out of a Novell SDK pack I am working with. They had backwards comp on everything they could, thats prob why it was like that.

Once again it would be nice to have a FAQ so poor Vlatko doesnt have to paste that code in every week when some on asks the same question. :rolleyes:

Yeah...and that list of C++ tutorial sites :)
