Question

How I can create child window with coordinates that are larger than 32767? For example:

HWND tmp = 
CreateWindow(
    _T( "BUTTON" ), _T( "Test" ),
    WS_CHILD | WS_VISIBLE,
    10, 45000, 80, 25,
    hWnd, (HMENU)1, (HINSTANCE)GetModuleHandle( NULL ), NULL );

This code creates button with coordinates 10;32767. Using of MoveWindow or SetWindowPos functions give same result.

I need to create window with scroll and child controls on it (simple form).

HWND CreateWindowExPatched( DWORD exStyle, LPCTSTR className, LPCTSTR title, DWORD style, int x, int y, int width, int height, HWND parent, HMENU menu, HINSTANCE instance, LPVOID param )
{
    HWND hWnd = NULL;

    ScrollWindow( parent, -x, -y, NULL, NULL );
    hWnd = CreateWindowEx( exStyle, className, title, style, 0, 0, width, height, parent, menu, instance, param );
    ScrollWindow( parent, x, y, NULL, NULL );

    return hWnd;
}

HWND CreateWindowPatched( LPCTSTR className, LPCTSTR title, DWORD style, int x, int y, int width, int height, HWND parent, HMENU menu, HINSTANCE instance, LPVOID param )
{
    return CreateWindowExPatched( 0, className, title, style, x, y, width, height, parent, menu, instance, param );
}
