LINK ERROR MESSAGE, please help

[cmontano]

what does this mean, and how do I fix it?
LINK : fatal error LNK1168: cannot open Debug/turbidostat.exe for writing
Error executing link.exe.

It happened after I first commented out this line:
pMainFrame->ShowWindow(m_nCmdShow);
then took out the comment bars --> "//"

It means that the exe file was in use when it tried to delete the existing one so it could create the new one. Possiblities are:
1) Your exe running.
2) your exe is running without a main window visible check task manager.
3) you have the exe open in devstudio as a resource file.

HTH,
Chris
