头大，全局热键无法多次使用sendkeys，求高人解决~
我的设想是在VB中设一个全局热键，当按下热键时，便往其化窗口发送数据，代码没有问题，调试也通过。当我按下热键时，第一次可以发送，但是当我再次按下热键时，就没有反映了。。。除非我手动激活一下窗体，
然后再最小化，然后再按热键。很头大，我想应该问题出在API上，但搞不懂呀，
跪求高人解决。。。
代码如下：
'在公共模块

If wParam = idHotKey Then
Dim lp As taLong, i2 As t2Int
lp.ll = lParam
LSet i2 = lp
If (i2.lWord = Modifiers) And i2.hword = uVirtKey Then
‘此处为接收到热键后需执行的操作
sendkeys "ok"
End If
End If
End If
'将之送往原来的Window Procedure
wndproc = CallWindowProc(preWinProc, hwnd, Msg, wParam, lParam)
End Function
'以下在 Form
Sub Form_Load()
Dim ret As Long
preWinProc = GetWindowLong(Me.hwnd, GWL_WNDPROC)
ret = SetWindowLong(Me.hwnd, GWL_WNDPROC, AddressOf wndproc)
idHotKey = 1 'in the range &h0000 through &hBFFF
Modifiers = MOD_ALT + MOD_SHIFT
uVirtKey = vbKeyG
ret = RegisterHotKey(Me.hwnd, idHotKey, Modifiers, uVirtKey)
End Sub
Private Sub Form_Unload(Cancel As Integer)
Dim ret As Long
'取消Message的截取，而使之又只送往原来的Window Procedure
ret = SetWindowLong(Me.hwnd, GWL_WNDPROC, preWinProc)

你可以在sendkeys前加这两句:
appactivate 目标窗口标题
doevents
sendkeys.... --------------------编程问答-------------------- 顶啦~~
补充：VB , API
