What are these error messages?

So I'm a beginner in Windows programming, All I've gotten to at the moment is opening an empty window with WINAPI. I was just wondering what these error messages mean, they don't stop the window from popping up, but I'm just running a simple example code from MSDN.com so I didn't think there would be any errors with it.

'savefile.exe': Loaded 'C:\Users\Michael\Documents\Visual Studio 2010\Projects\savefile\Debug\savefile.exe', Symbols loaded.
'savefile.exe': Loaded 'C:\Windows\SysWOW64\ntdll.dll', Cannot find or open the PDB file
'savefile.exe': Loaded 'C:\Windows\SysWOW64\kernel32.dll', Cannot find or open the PDB file
'savefile.exe': Loaded 'C:\Windows\SysWOW64\KernelBase.dll', Cannot find or open the PDB file 

The list goes on for about 20 different "PDB files", but I'm not even sure what a PDB file is, let alone how to fix it. I'm running the windows Visual C++ 2010 express edition without any add-ons or pluggins. OS = Windows 7

It's not stopping my code from running at the moment, but I get the feeling it could get troublesome as my code gets more involved. I don't think it's a good thing that it's having trouble opening my .dll's

Any suggestions?

They're files that, if they existed, would help you with debugging those libraries. It's not something you need to worry about. The program is having no trouble opening dll files.

Hi newbieg,

Can you post your code and compiler output?
