hallo, C++(ers)

I have a problem after making the main int window.
the I wane whit a pus of a a button display a other window but is don't show up.

LRESULT CALLBACK DiallogProcedure(HWND hWnd, UINT msg , WPARAM wp , LPARAM lp )
{
    switch (msg)
    {

    case WM_CLOSE:
        DestroyWindow(hWnd);
        break;
    default:
        return DefWindowProc(hWnd, msg, wp, lp);
    }

}


void registerDialogClass(HINSTANCE HInst)
{
    WNDCLASSW dialog = { 0 };

        dialog.hbrBackground = (HBRUSH)COLOR_WINDOW;
        dialog.hCursor = LoadCursor(NULL, IDC_CROSS);
        dialog.hInstance = HInst;
        dialog.lpszClassName = L"myDialogClass";
        dialog.lpfnWndProc = DiallogProcedure;

        RegisterClassW(&dialog);

}


void dispplayDialog(HWND hWnd)
{
    CreateWindowW(L"myDaillogClass", L"Diallog", WS_VISIBLE | WS_OVERLAPPEDWINDOW, 400, 400, 200, 200, hWnd, NULL, NULL, NULL);

}

PLEASE ALWAYS USE CODE TAGS (the <> formatting button) when posting code.
It makes it easier to read your code and also easier to respond to your post.

Huh?

1.

Please learn to use code tags, they make reading and commenting on source code MUCH easier.

How to use code tags: http://www.cplusplus.com/articles/jEywvCM9/

There are other tags available.

HINT: you can edit your post and add code tags.

Some formatting & indentation would not hurt either

2. Dialog boxes are specialized WinAPI entities, they are not created and displayed as you would your main window.
https://docs.microsoft.com/en-us/windows/win32/dlgbox/dialog-box-overviews

3. The easiest way to create a dialog box is using a template in a resource script. Creating and using dialog boxes:

Dialog templates can be created in memory:

4. A Message Box is a pre-designed dialog box that is easy to manage and display:

is ok now

the window Class name was not Correctly spelled

    hWnd = CreateWindowW(L"myDialogClass", L"TestWindow", WS_OVERLAPPEDWINDOW | WS_VISIBLE,
        CW_USEDEFAULT, CW_USEDEFAULT, 100, 100,
        NULL, NULL, NULL, 0);
