hi!

i need to debug an "old" vc++ 6.0 programm and want to compile it
using vs2008pro. can i do this, basically?

i tried to do it, but got the error :

"Error61 fatal error C1083: File (Include) can not be opened:
"fstream.h": No such file or directory"

fstream.h is included by the following line:

#include <fstream.h>

it looks like something is missing. before i installed vs2008pro i
already installed the newest "windows sdk" (for server2008 and
framework 3.5). so as far as i know all files should be available,
shouldn't they?

i did a search for fstream.h and fstream.cpp, found them somewhere in
a project of someone else and copied them to an additional include-
folder for this project. when i recompiled, i got like 40 errors over
not defined variables etc.. so this din't lead anywhere.

so my question is, how can i compile old vc++ 6.0 projects in
vs2008pro, so that everything runs? imho, this must be possible.
microsoft has an interrest that this is possible.

Arthur:

As others have noted, you need to change your iostream header #includes. But,
really, you should not have been using the old iostream library in VC6 (or VC5).

Actually, you could perform this update in VC6, so that you can separate this
iostream issue from other issues you might have with the migration.
