展示从C＃窗口停止进程 [英] Stop a process from showing a window from C#

问题描述

我想自动执行上没有用户交互启动创建GUI窗口的应用程序，但我无法弄清楚如何隐藏实际的窗口。

我试着使用的ProcessStartInfo这样的：

 的Process.Start（新的ProcessStartInfo {
 UseShellExecute =假， 
 CreateNoWindow = TRUE，
 WindowStyle = ProcessWindowStyle.Hidden，
 
 //其他属性在这里
}）; 
  

但窗口仍显示。

我也试过自旋等待存在的窗口，然后隐藏它：

 而（process.MainWindowHandle = = IntPtr.Zero）{} 
 ShowWindowAsync（process.MainWindowHandle，SW_HIDE）; 
  

这很不幸，使得一秒钟左右的约1/16号窗口一闪，我倒要避免它，如果在所有可能的。

我现在的想法是一起创建的勾，但我不确定是什么钩抢，也不如果它甚至会工作。

$ b $任何提示？

解决方案

所需的工艺窗口样式（实际上映射到单一的b

的 SW _ 常量）被传递到其它应用程序的的WinMain 的功能，但并不意味着粗鲁的应用程序韩元T不理你发送的任何值。

您可以通过创建另一个虚拟桌面 User32.CreateDesktop ，然后用 Kernel32.CreateProcess ，确保传递正确的桌面名称为的StartInfo 结构的一部分。

I'm trying to automate an application that creates a GUI window on startup that has no user interaction, but I can't figure out how to hide the actual window.

I've tried using ProcessStartInfo thus:

Process.Start(new ProcessStartInfo {
    UseShellExecute = false,
    CreateNoWindow = true,
    WindowStyle = ProcessWindowStyle.Hidden,

    // other properties here
});

But the window still shows up.

I've also tried spin-waiting for the window to exist, and then hiding it:

while (process.MainWindowHandle == IntPtr.Zero) {}
ShowWindowAsync(process.MainWindowHandle, SW_HIDE);

This, unfortunately, makes the window flash for about 1/16th of a second or so, and I'd like to avoid it if at all possible.

My current thoughts are along the line of creating a hook, but am unsure of what hooks to grab, nor if it will even work.

Any tips?

解决方案

The desired process window style (actually mapped to one of the SW_ constants) is passed to the other application's WinMain function, but that doesn't mean a rude application won't just ignore whatever value you send.

You can pull it off by creating another virtual desktop using User32.CreateDesktop, then use Kernel32.CreateProcess, making sure to pass the correct desktop name as part of the STARTINFO structure.
