可能是在下没有说清楚

我的意思是用api为窗体设置热键后，当一个窗口把程序窗体遮盖后，按下热键就可以让窗体显示出来。
这个没什么问题，不过当窗体隐藏后，按下热键怎么能让它不是隐藏呢？，也就是说热键触发了哪个事件？
谢谢

窗体
Option Explicit
Sub Form_Load()
Dim ret As Long
'??原来的window程序地址
preWinProc = GetWindowLong(Me.hwnd, GWL_WNDPROC)
'用自定?程序代替原来的window程序
ret = SetWindowLong(Me.hwnd, GWL_WNDPROC, AddressOf wndproc)

Modifiers = MOD_ALT + MOD_SHIFT + MOD_CONTROL

uVirtKey = vbKeyG

'注册Showhotkey in the range ＆h0000 through ＆hBFFF
ret = RegisterHotKey(Me.hwnd, ShowHotKey, Modifiers, uVirtKey)

Me.Hide
End Sub

Private Sub Form_Unload(Cancel As Integer)
Dim ret As Long
'取消Message的截取，使之送往原来的window程序
ret = SetWindowLong(Me.hwnd, GWL_WNDPROC, preWinProc)
Call UnregisterHotKey(Me.hwnd, ShowHotKey)
End Sub

没这么复杂吧？在当前窗体捕获到热键键值后，直接响应一个窗体SHOW的函数即可。

[hxy2003]

注册全局热键是麻烦，窗口关闭时又要注销，否则会出错

使窗体获得焦点

先用load form1，然后用form1.show和form1.hide就可以了
