这个问题已经是老问题了！<p>Option Explicit<br>Private Declare Function SetWindowPos Lib "user32" (ByVal hwnd As Long, _<br>ByVal hWndInsertAfter As Long, ByVal x As Long, ByVal y As Long, _<br>ByVal cx As Long, ByVal cy As Long, ByVal wFlags As Long) As Long<p>Private Const HWND_TOPMOST = -1<br>Private Const HWND_NOTOPMOST = -2<br>Private Const SWP_NOSIZE = &H1<br>Private Const SWP_NOMOVE = &H2<p>Public Sub SetOnTop(frm As Form, Topmost As Boolean)<br>If Topmost Then<br>SetWindowPos frm.hwnd, HWND_TOPMOST, 0, 0, 0, _<br>0, SWP_NOSIZE Or SWP_NOMOVE<br>Else<br>SetWindowPos frm.hwnd, HWND_NOTOPMOST, 0, 0, 0, _<br>0, SWP_NOSIZE Or SWP_NOMOVE<br>End If<br>End Sub<br>以上的程式码放在一个 Module 中<p>在 Form_Load 中输入：<br>SetOnTop Me, True<p><br>若非MDIForm直接在Show后面加 1 即可<br>Form.Show 1
