SendMessage（退格）无法正常工作！

Question

Private Const WM_KEYDOWN = &H100
Private Const WM_KEYUP = &H101
Private Const VK_BACKSPACE = &H8

Private Overloads Shared Function SendMessage(ByVal hWnd As IntPtr, _
ByVal msg As Integer, ByVal wp As IntPtr, ByVal lp As IntPtr) As IntPtr
End Function

我发这样的信息：

SendMessage(windHandle, WM_KEYDOWN, CType(VK_BACKSPACE, IntPtr), CType(&HC0510001, IntPtr))
SendMessage(windHandle, WM_KEYUP, CType(VK_BACKSPACE, IntPtr), CType(&HC0510001, IntPtr))

我也在这之前尝试过keybd_event：

Call keybd_event(&H8, MapVirtualKey(&H8, 0), 0, 0)
Call keybd_event(&H8, MapVirtualKey(&H8, 0), KEYEVENTF_KEYUP, 0)

有人可以帮忙吗？ 谢谢！

解决了......这是我的错！由于一些疯狂的旧代码布尔值，我的函数没有激发！

所以如果有人需要这个，上面的sendmessage适用于退格！

抱歉，伙计们：）
