Then you can truck on over to the C++ support forums and ask them how to fix the rest...
This forum is for Pelles C, not Microsoft C++.
I think you misunderstood (part of) his problem.
He wants to keep using Pelle's C but somehow after uninstalling Visual C++ Express, the associations did not get restored to the previous state but to default state (the icon for .C shows it associated with Notepad, which IIRC is the default).
Simplest way to restore those associations is to right click any of those files, select "Open with...", then "Choose Default program...", select Pelle's C IDE and make sure that the check box "Always use the selected program...." is checked before hitting ok. The do the same for .h, .inc, .ppj and .ppx at least, that should get him going again...
