RE: System.Diagnostics.ProcessStartInfo

Tech-Archive recommends: Repair Windows Errors & Optimize Windows Performance

Hi Jeffrey, Peter...

The thing that made me curious is that the app I'm launching is a console
app, but it still spawns a separate window.

To be specific, I'm writing a little application that helps with installing
an ASP.Net website, so my .net program is spawning aspnet_regiis.exe to make
sure the right version of .net is the default. That's a console app.

But when I use the Process.Start() code I posted, it ignores the
CreateNoWindow option and spawns a separate window. My .net app is also a
console app.

It seems that the flag just doesn't do anything at all.

Thanks
Mark

Hi Mark,

Yes, Pete is right. CreateNoWindow property internally encapsulates the
CREATE_NO_WINDOW flag passing to the Win32 CreateProcess API. From the
document below, you will see that it is merely used to hide the console
application window. This flag is ignored if the application is not a
console application:
http://msdn2.microsoft.com/en-us/library/ms684863(VS.85).aspx

If one GUI application is intended to be used to perform the background
processing work, it should accept certain command line arguments to run
without any GUI. Letting the end user to hide its GUI window is not a good
practise.

Thanks.

Best regards,
Jeffrey Tan
