Hello, I've made some programs a year or two ago and since then, I have been updating visual studio express. I am trying to open my source code but it says it is incompatible with the version I have.. I have tried uninstalling and reinstalling 2005 and 2008 express editions but still does not work. How can I tell what version I used with my source code? Thanks

Open the .sln file with a text editor, it should say the version used to create it up near the top.

The code itself is fine, that error means the project or solution files are incompatible. Usually you get a prompt to convert or import such files, but perhaps you're trying to do it in a fashion that will not: try launching the newest version of VS you have and opening the .sln or project files manually from the File menu.

If that fails you could just create a new project and add your code to it, for a quick and dirty fix.

ah ok, thanks :)
