I get the following error when compiling under MS VC++:

It compiles under the 2003 version though... (at least I thought that
was the version I used at school). When I opened it at home in the
2005 version I was prompted to convert the project, after that I tried
building and got the error above. I'm quite new to Microsoft's
environment and the .NET-stuff (and I only use it because my
university uses that). I think there is a simple explanantion, but
can't find it myself.

As Victor pointed out, this does not really belong here as it seems to
apply to a particular environment where better newsgroups exist. One
thing is in order though: you should learn to read the error-messages.
Here, it is evident that the file compiles just fine. The linker just
tells you that there is a function you have defined multiple times -
once in atlsd.lib and once in iorw-vc7.lib. Looking at that last name
should tell you that the project seemingly requests to link a 2003-
project (VC7). Most likely, you should remove that lib from your
project.
