已知窗体句柄，向指定窗体发送按键怎么写？

[lxcooi]

一定要用API因为那个窗体是隐藏的。
现在我要发送的是F2键

SendMessage(hwnd, WM_KEYDOWN, …………
后面怎么写？

!真晕啊！！！
Option Explicit
Private Declare Function SendMessage Lib "user32" Alias "SendMessageA" (ByVal hwnd As Long, ByVal wMsg As Long, ByVal wParam As Long, lParam As Any) As Long

Private Const WM_CHAR = &H102

Private Sub Command1_Click()
SendMessage Me.hwnd, WM_CHAR, Asc(Text1.Text), 0
End Sub

Private Sub Form_KeyPress(KeyAscii As Integer)
Me.Print Chr(KeyAscii)
End Sub

老大，我要发送的是F2键，不是字符！！

谢谢解决了：
写法是
Api.SendMessage Me.hwnd, &H100, vbKeyF2, 0
