如何让窗体总在最前面?
'API函数声明
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
'常量声明
Private Const SWP_NOSIZE = &H1
Private Const SWP_NOMOVE = &H2
Private Const HWND_TOPMOST = -1
Private Const HWND_NOTOPMOST = -2
' 在某个form里写:
SetWindowPos me.hWnd,WND_TOPMOST,0,0,0,0, SWP_NOMOVE '或下面
SetWindowPos me.hWnd,WND_TOPMOST,0,0,0,0, SWP_NOSIZE
