I have the following code which is working. My callback method is called with the program\'s output as it is generated.
var proc = new System.Diagnostics.Pr
I spent almost 2 days to solve this problem... Here is the solution: http://forums.asp.net/p/1032763/3054483.aspx
Briefly, you need to set the "App Pool's Identity" same as your "proc.StartInfo.UserName" and "proc.StartInfo.Password".
You can either change the Identify of "DefaultAppPool" or create a new "App Pool" using your "proc.StartInfo.UserName" as the Identify.
Of course, if you create a new "App Pool", you have to assign your asp.net web application use this "App Pool".
Hope it's useful, good luck. lzch
I think the problem is in security mechanism of UAC: your initial application have no rights to read output of the another user's process (even if it is a child process). Try to start your application with administrator privilegies and see if you code works.
I think the best way to solve your problem is to redirect your child process output to a file and make a thread in your initial apllication to check that file for updates.
