VB使窗口前置

A.EXE已经窗口最大化，但被其他程序窗口遮挡置底，VB怎么才能使其窗口最大化前置？求代码！谢谢！

Answer 1

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
Private Const HWND_TOPMOST& = -1
' 将窗口置于列表顶部，并位于任何最顶部窗口的前面
Private Const SWP_NOSIZE& = &H1
' 保持窗口大小
Private Const SWP_NOMOVE& = &H2
' 保持窗口位置
Private Sub Form_Load()
SetWindowPos Me.hwnd, HWND_TOPMOST, 0, 0, 0, 0, SWP_NOMOVE Or SWP_NOSIZE
' 将窗口设为总在最前
End Sub

是第三方窗口

是指遮挡A.EXE的程序？

A.exe最小化或窗口置底，怎么样使其窗口前置最大化

追答

Private Sub Form_Load()'最大化
Me.WindowState = vbMaximized
End Sub
Option Explicit

''使指定窗口总在最前
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

Const HWND_TOPMOST = -1
Const SWP_NOMOVE = &H2
Const SWP_NOSIZE = &H1
Const SWP_NOZORDER = &H8

Sub SetFormTopmost(TheForm As Form)

SetWindowPos TheForm.hwnd, HWND_TOPMOST, 0, 0, 0, 0, _
SWP_NOZORDER + SWP_NOMOVE + SWP_NOSIZE

End Sub

Sub Form_Load()

SetFormTopmost Me ''只需要改动这里，ME换成你想放在最前的窗体名

End Sub

**调试的时候没有效果，生成程序后就行了

窗体总是置顶(API)
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 Const HWND_TOPMOST = -1
Const SWP_NOMOVE = &H2
Const SWP_NOSIZE = &H1 Private Sub Form_Load()
SetWindowPos Me.hWnd, HWND_TOPMOST, 0, 0, 0, 0, SWP_NOMOVE Or SWP_NOSIZE
End Sub
'为了防止节外生枝，还可加入如下代码：
Private Sub Timer1_Timer() 'Timer1.Interval=200
SetWindowPos Me.hWnd, HWND_TOPMOST, 0, 0, 0, 0, SWP_NOMOVE Or SWP_NOSIZE
End Sub
