output error in c++
I am having a very strange problem in a simple program and have been unable to reach any logical conclusion. When I redirect output from my program to a file, then I get a different result that I get when printing to stdout. When I print to a file, the result is correct. I don't understand why it would be different in the first place. He...

Visual Studio 2010 Output Panel Not Updating Postbuild Output
I just recently upgraded from VS2008 to VS2010. Because I do a lot of remote debugging (over VPN), I use Post-Build events to copy the compiled binaries and PDB's to the target machine before running. I do this by calling a batch file that (among other things) executes Robocopy. In VS2008, the Output panel would display robocopy's out...
