I have got some old sources written in Visual Basic. There are *.bas, *.cls, *.frm and *.vbp files. As I understand, vbp is a project file. But I cannot open it with my Visual Studio 2008.
What version of VS should I install to open *.vbp file? Google says it is Visual Studio 6, but I am not sure and I cannot find Visual Studio 6 for downloading. Is there any publicly available free edition of Visual Studio 6 with Visual Basic?
Thanks.
vbp is indeed a VB 5/6 Project File.
VS6/VB5/VB6 are not free, so if you want to build the project you will need to spend $5 on ebay.
The VB5 Control Creation Edition (build COM components only) was the only free version MS released.
Older versions of VS.net included a way to import a VBP and upgrade it to VB.NET, but YMMV (significantly).
Edit; If you just want to look at the source/project structure all the files except .frx are plain ascii.
