CreateNoWindow only applies to console mode apps, it won't create the console window. 

WindowStyle only applies to native Windows GUI apps. It is a hint passed to the <a href="http://msdn.microsoft.com/en-us/library/windows/desktop/ms633559%28v=vs.85%29.aspx" rel="noreferrer">WinMain() entry point</a> of such a program. Fourth argument, nCmdShow, telling it how to show its main window. This is the same hint that appears as the "Run" setting in a desktop shortcut. Note that "hidden" is not an option there, few properly designed Windows program honor that request. Since that snookers the user, he can't get the program activated anymore and can only kill it with Task Manager.

Using Reflector, it looks like <a href="http://msdn.microsoft.com/en-us/library/system.diagnostics.processstartinfo.windowstyle.aspx" rel="noreferrer"><code>WindowStyle</code></a> is used if <a href="http://msdn.microsoft.com/en-us/library/system.diagnostics.processstartinfo.useshellexecute.aspx" rel="noreferrer"><code>UseShellExecute</code></a> is set, otherwise it uses <a href="http://msdn.microsoft.com/en-us/library/system.diagnostics.processstartinfo.createnowindow.aspx" rel="noreferrer"><code>CreateNoWindow</code></a>.

In MSDN's example, you can see how they set it:

<pre><code>// Using CreateNoWindow requires UseShellExecute to be false
myProcess.StartInfo.UseShellExecute = false;
// You can start any process, HelloWorld is a do-nothing example.
myProcess.StartInfo.FileName = "C:\\HelloWorld.exe";
myProcess.StartInfo.CreateNoWindow = true;
myProcess.Start();
</code></pre>

In the other example, its just below because <code>UseShellExecute</code> is defaulted to true

<pre><code>// UseShellExecute defaults to true, so use the WindowStyle
ProcessStartInfo startInfo = new ProcessStartInfo("IExplore.exe");
startInfo.WindowStyle = ProcessWindowStyle.Minimized;
</code></pre>

As Hans said, WindowStyle is a recommendation passed to the process, the application can choose to ignore it.

CreateNoWindow controls how the console works for the child process, but it doesn't work alone.

CreateNoWindow works in conjunction with UseShellExecute as follows:

To run the process without any window:

<pre><code>ProcessStartInfo info = new ProcessStartInfo(fileName, arg); 
info.CreateNoWindow = true; 
info.UseShellExecute = false;
Process processChild = Process.Start(info); 
</code></pre>

To run the child process in its own window (new console)

<pre><code>ProcessStartInfo info = new ProcessStartInfo(fileName, arg); 
info.UseShellExecute = true; // which is the default value.
Process processChild = Process.Start(info); // separate window
</code></pre>

To run the child process in the parent's console window

<pre><code>ProcessStartInfo info = new ProcessStartInfo(fileName, arg); 
info.UseShellExecute = false; // causes consoles to share window 
Process processChild = Process.Start(info); 
</code></pre>

When I start a new process, what difference does it make if I use the 

<pre><code>WindowStyle = Hidden
</code></pre>

or the 

<pre><code>CreateNoWindow = true
</code></pre>

property of the <code>ProcessStartInfo</code> class?

.NET - WindowStyle = hidden vs. CreateNoWindow = true?

Windows

当我启动一个新进程时，如果我使用WindowStyle = Hidden或者CreateNoWindow = trueProcessStartInfo类的属性？
