使用c＃删除外部应用程序的标题栏

我的应用程序启动了另一个外部应用

我想在启动后删除此外部应用程序的标题栏。

这是可行的，如果是这样的话怎么办？

根据评论，我使用下面的工作代码

//Finds a window by class name [DllImport("USER32.DLL")] public static extern IntPtr FindWindow(string lpClassName, string lpWindowName); //Sets a window to be a child window of another window [DllImport("USER32.DLL")] public static extern IntPtr SetParent(IntPtr hWndChild, IntPtr hWndNewParent); //Sets window attributes [DllImport("USER32.DLL")] public static extern int SetWindowLong(IntPtr hWnd, int nIndex, int dwNewLong); //Gets window attributes [DllImport("USER32.DLL")] public static extern int GetWindowLong(IntPtr hWnd, int nIndex); [DllImport("user32.dll", EntryPoint = "FindWindow", SetLastError = true)] static extern IntPtr FindWindowByCaption(IntPtr ZeroOnly, string lpWindowName); //assorted constants needed public static int GWL_STYLE = -16; public static int WS_CHILD = 0x40000000; //child window public static int WS_BORDER = 0x00800000; //window with border public static int WS_DLGFRAME = 0x00400000; //window with double border but no title public static int WS_CAPTION = WS_BORDER | WS_DLGFRAME; //window with a title bar public void WindowsReStyle() { Process[] Procs = Process.GetProcesses(); foreach (Process proc in Procs) { if (proc.ProcessName.StartsWith("notepad")) { IntPtr pFoundWindow = proc.MainWindowHandle; int style = GetWindowLong(pFoundWindow, GWL_STYLE); SetWindowLong(pFoundWindow, GWL_STYLE, (style & ~WS_CAPTION)); } } }

无需注入任何东西，您只需使用API​​修改窗口样式位，例如，这适用于记事本，但YMMV取决于您正在玩的应用程序。

 //Get current style lCurStyle = GetWindowLong(hwnd, GWL_STYLE) //remove titlebar elements lCurStyle = lCurStyle And Not WS_CAPTION lCurStyle = lCurStyle And Not WS_SYSMENU lCurStyle = lCurStyle And Not WS_THICKFRAME lCurStyle = lCurStyle And Not WS_MINIMIZE lCurStyle = lCurStyle And Not WS_MAXIMIZEBOX //apply new style SetWindowLong hwnd, GWL_STYLE, lCurStyle //reapply a 3d border lCurStyle = GetWindowLong(hwnd, GWL_EXSTYLE) SetWindowLong hwnd, GWL_EXSTYLE, lCurStyle Or WS_EX_DLGMODALFRAME //redraw SetWindowPos hwnd, 0, 0, 0, 0, 0, SWP_NOMOVE Or SWP_NOSIZE Or SWP_FRAMECHANGED

 Process[] processes = Process.GetProcessesByName("notepad"); IntPtr windowHandle = processes[0].MainWindowHandle; const int GWL_STYLE = (-16); const UInt32 WS_VISIBLE = 0x10000000; SetWindowLong(windowHandle, GWL_STYLE, (WS_VISIBLE));`

通常，除非您正在启动的应用程序直接支持in（例如，如果需要命令行开关来删除标题栏），则不能这样做。

您只能控制ProcessStartInfo类中已存在的内容（即打开一个新窗口，启动最小化/最大化等…）。

嗯，亚历克斯从来没有详细说明代码，至少它不是一个即插即用的解决方案，但仍然主要归功于他……除非你使用“SetParent”把它放在一边它在某种容器中（例如表单或面板）只是想我会分享结果。

再次，谢谢Alex

这与之前提出的问题非常相似，我很确定答案是你不能这样做。 （或者，如果可以，您需要深入了解Windows API，这可能具有挑战性，具体取决于您的经验。）
