I use Visual Studio 2010 C++ and my project builds without errors but when I run it I get this. I am on Windows XP.

PDB is a debug information file used by Visual Studio. These are system DLLs, which you don't have debug symbols for. Go to Tools->Options->Debugging->Symbols and select checkbox "Microsoft Symbol Servers", Visual Studio will download PDBs automatically. Or you may just ignore these warnings if you don't need to see correct call stack in these modules.
