用keybd_event吧，同样的作用。
参考：
Private Declare Sub keybd_event Lib "user32" (ByVal bVk As Byte, ByVal bScan As Byte, ByVal dwFlags As Long, ByVal dwExtraInfo As Long)
Private Sub Command1_Click()
Text1.SetFocus
keybd_event vbKeyA, 0, 0, 0
End Sub
vbKeyA是键码常数，对应字符“a”在MSDN里可查看全部。

Private Const WM_SETFOCUS = &H7
Private Const WM_LBUTTONDOWN = &H201
SendMessage Me.Text1.hwnd, WM_SETFOCUS , vbKeyA, vbNullString
或
SendMessage Me.Text1.hwnd, WM_LBUTTONDOWN, vbKeyA, vbNullString
