What is your &quot;STARTUP_INFO&quot; struct like?<br />
<br />
It should be<br />
<br />
&nbsp;STARTUPINFO siStartInfo;<br />
<br />
&nbsp; &nbsp; // Set up the start up info struct.<br />
&nbsp; &nbsp; ZeroMemory(&amp;siStartInfo,si<wbr />zeof(START<wbr />UPINFO));<br />
&nbsp; &nbsp; siStartInfo.cb = sizeof(STARTUPINFO);<br />
&nbsp; &nbsp; siStartInfo.dwFlags = STARTF_USESHOWWINDOW;<br />
&nbsp; &nbsp; siStartInfo.wShowWindow = SW_HIDE;<br />

I modified the STARTUPINFO as you described, it didn't make a difference.. <br />
actually my problem is not at the startup. it's when I close the GUI window..

I start a process using CreateProcess as follows, which starts with a minimized DOS console window which, in turn, starts a GUI. I want the console window closed automatically when the GUI is closed. I tried the following code. It doesn't work.<br />

C++ is an intermediate-level general-purpose programming language, not to be confused with C or C#. It was developed as a set of extensions to the C programming language to improve type-safety and add support for automatic resource management, object-orientation, generic programming, and exception handling, among other features.
