一个简单的问题：如何使用sendmessage向其他程序发送一个按钮click的消息？

[jisheng]

如题。

我现在用的是SendMessage hwndinstall, &HF5, vbKeySpace, 0
这样子另一个程序的那个按钮就会处于“下压”的状态，不会弹起来，不爽

[qflash]

SendMessage hwdb, WM_KEYDOWN, vbKeySpace, 0
SendMessage hwdb, WM_CHAR, vbKeySpace, 0
SendMessage hwdb, WM_KEYUP, vbKeySpace, 0

SendMessage Command2.hwnd, &HF5, 0, 0
给分儿，好久不来，好像级别什么的都低了：）

[qflash]

就是

Private Declare Function SendMessage Lib "user32.dll" Alias "SendMessageA" (ByVal hwnd As Long, ByVal wMsg As Long, ByVal wParam As Long, lParam As Any) As Long
Private Const BM_CLICK As Long = &HF5

SendMessage Command1.hwnd, BM_CLICK, 0, ByVal 0&
