C# 在c语言中使用WM_-Close#
我正在使用下面的代码通过在任务栏中搜索窗口名称来关闭窗口。 但有一种情况,我的窗口不会出现在任务栏上。在这种情况下,C# 在c语言中使用WM_-Close#,c#,C#,我正在使用下面的代码通过在任务栏中搜索窗口名称来关闭窗口。 但有一种情况,我的窗口不会出现在任务栏上。在这种情况下,WM_Close无法关闭窗口。使用WM\u Close void DaemonTerminamtionHook_KeyPressed(object sender, KeyPressedEventArgs e) { DaemonResult = MessageBox.Show("Are you sure, you want to Terminate D
WM_Close
无法关闭窗口。使用WM\u Close
void DaemonTerminamtionHook_KeyPressed(object sender, KeyPressedEventArgs e)
{
DaemonResult = MessageBox.Show("Are you sure, you want to Terminate Daemon?", "Terminate Daemon", MessageBoxButtons.YesNo, MessageBoxIcon.Exclamation);
if (DaemonResult == DialogResult.Yes)
{
//Free the resources of ShellBasics and terminate Daemon here.
IntPtr hWnd = FindWindowByCaption(IntPtr.Zero, "DAEMON TAB BAR");
bool ret = CloseWindow(hWnd);
}
}
//WM_Close
[DllImport("user32.dll", EntryPoint = "FindWindow", SetLastError = true)]
static extern IntPtr FindWindowByCaption(IntPtr ZeroOnly, string lpWindowName);
[DllImport("user32.dll", CharSet = CharSet.Auto)]
static extern IntPtr SendMessage(IntPtr hWnd, UInt32 Msg, IntPtr wParam, IntPtr lParam);
static uint WM_CLOSE = 0x10;
static bool CloseWindow(IntPtr hWnd)
{
SendMessage(hWnd, WM_CLOSE, IntPtr.Zero, IntPtr.Zero);
return true;
}
现在使用下面的代码…但是在 IntPtr hWnd=PostMessage(IntPtr.Zero,WM_CLOSE,IntPtr.Zero,IntPtr.Zero) 在哪里提供窗口名称以关闭该窗口
编辑:对不起,误读了你的问题
改用 @Preet,谢谢你的支持。你能告诉我如何传递参数:void PostMessageSafe(HandleRef hWnd,uint msg,IntPtr wParam,IntPtr lParam)@Preet,在这里传递窗口名的位置吗?@Preet,请参考顶部的更新代码,它给出了一些错误,因为参数不匹配,请告诉我在哪里提供windows名称以便关闭它。我建议阅读以使用类名设置窗口,以便findwindow可以找到它。或者使用SPY++在dev中查找此值
