请问在VB中怎样能使窗体置顶？让他一直保持在当前所有窗口前面，请详细讲解，谢谢！
用API
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
Public Const HWND_TOPMOST = -1
Public Const SWP_NOMOVE = &H2
Public Const SWP_NOSIZE = &H1
Public Const SWP_NOZORDER = &H8
将下面的子程序放到模块中
Public Sub SetFormTopmost(TheForm As Form)
SetWindowPos TheForm.hwnd, HWND_TOPMOST, 0, 0, 0, 0, _
SWP_NOZORDER + SWP_NOMOVE + SWP_NOSIZE
End Sub
最后，通过调用该子程序设置你想要放置的窗体。例如，你想将窗体frmMyForm放在最前面，代码如下：
SetFormTopmost frmMyForm.
SetFormTopmost frmMyForm
