API函数中的常量问题
假如声明了这么一个API函数：Private Declare Function SetWindowPos Lib "user32" (ByVal hwnd As Long, ByVal hWndInsertAfter As Long, ByVal X As Long, ByVal Y As Long, ByVal cx As Long, ByVal cy As Long, ByVal wFlags As Long) As Long
在源代码中我调用了它
SetWindowPos display.hwnd, HWND_TOPMOST, 2, 2, 0, 0, SWP_NOSIZE
发现VB不认识HWND_TOPMOST和SWP_NOSIZE，都是EMPTY值。
这两个常量怎么让VB认识啊？
