Question

我想在其他应用程序中激活启动按钮，我使用间谍++检查按钮样式，我c bs_pushbutton。我尝试使用win api来做它。我试过WM_SETFOCUS并输入密钥来做它，但是失败了

这些是我的代码



    Dim hwnd As Int32 = apiFindWindowEx(HWND_DESKTOP, 0, Nothing, "Open File -     Security Warning")
    Dim cwnd As Int32 = apiFindWindowEx(hwnd, 0, Nothing, "&Run")
    Dim i As Integer = SendMessage(cwnd, BS_PUSHBUTTON, 0, 0)

Dim hwnd As Int32 = apiFindWindowEx(HWND_DESKTOP, 0, Nothing, "Open File - Security Warning") Dim cwnd As Int32 = apiFindWindowEx(hwnd, 0, Nothing, "&Run") Dim i As Integer = SendMessage(cwnd, BS_PUSHBUTTON, 0, 0) 我宣布它是BS_PUSHBUTTON ???的正确值

我怎样才能运行app按钮事件？

目前还不清楚你在这个问题中究竟要求什么。我不确定您是在尝试启用按钮还是模拟点击它。

无论如何，对于前者，您只需使用EnableWindow()：

EnableWindow( cwnd, true );

或者：

Button_Enable( cwnd, true );

对于后者，您可以使用SetActiveWindow()和BM_CLICK：

SetActiveWindow( hwnd );
SendMessage( cwnd, BM_CLICK, 0, 0 );

在其他应用程序中激活按钮
