调用API的SetWindowsPos函数出错！

[unser]

为什么我调用API的SetWindowsPos函数，无法使窗口总在最前面
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 Sub Form_Load()
SetWindowPos Me.hwnd, HWND_TOPMOST, 0, 0, 0, 0, SWP_NOMOVE Or SWP_NOSIZE
Or SWP_SHOWWINDOW
End Sub

HWND_TOPMOST 的值设没有？

[netsing]

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

Private Sub Form_Load()
SetWindowPos Me.hwnd, HWND_TOPMOST, 0, 0, 0, 0, SWP_NOMOVE Or SWP_NOSIZE Or SWP_SHOWWINDOW
End Sub
先设好HWND_TOPMOST 的值

[ikey]

HWND_TOPMOST
SWP_NOMOVE
SWP_NOSIZE
SWP_SHOWWINDOW

都需要设定的吧?!

[fullor2000]

HWND_TOPMOST
SWP_NOMOVE
SWP_NOSIZE
SWP_SHOWWINDOW
都需要设定一个值，到windows.inc中去查。
比如
const SWP_NOMOVE=&H2

[fraser01]

请在你的模块内设置如下常量：
Public Const HWND_BOTTOM = 1
Public Const HWND_BROADCAST = &HFFFF&
Public Const HWND_DESKTOP = 0
Public Const HWND_NOTOPMOST = -2
Public Const HWND_TOP = 0
Public Const HWND_TOPMOST = -1
Public Const SWP_DRAWFRAME = SWP_FRAMECHANGED
Public Const SWP_FRAMECHANGED = &H20 ' The frame changed: send WM_NCCALCSIZE
Public Const SWP_HIDEWINDOW = &H80
Public Const SWP_NOACTIVATE = &H10
Public Const SWP_NOCOPYBITS = &H100
Public Const SWP_NOMOVE = &H2
Public Const SWP_NOOWNERZORDER = &H200
Public Const SWP_NOREDRAW = &H8
Public Const SWP_NOSIZE = &H1
Public Const SWP_NOREPOSITION = SWP_NOOWNERZORDER
Public Const SWP_NOZORDER = &H4
Public Const SWP_SHOWWINDOW = &H40

完成后你再试一下

同时，X，Y，CX，CY的值是表示你窗口的位置和高度、宽度的，所以不能全部为零，
要设一个值。你可参考如下：
SetWindowPos Me.hwnd, HWND_TOPMOST, 0, 0, 50, 100, SWP_NOMOVE Or SWP_NOSIZE
Or SWP_SHOWWINDOW

[lihonggen0]

Const HWND_TOPMOST = -1
Const HWND_NOTOPMOST = -2
Const SWP_NOSIZE = &H1
Const SWP_NOMOVE = &H2
Const SWP_NOACTIVATE = &H10
Const SWP_SHOWWINDOW = &H40
Private Declare Sub 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)

Private Sub Form_Activate()

'Set the window position to topmost
SetWindowPos Me.hWnd, HWND_TOPMOST, 0, 0, 0, 0, SWP_NOACTIVATE Or SWP_SHOWWINDOW Or SWP_NOMOVE Or SWP_NOSIZE
End Sub
