I have a need to modify some code on an application I wrote using Visual Basic 5. It's a fairly simple app. The problem is that I've lost my registration key for the VB5 software and no longer have the machine that it was installed on. I've downloaded and installed VB10 Express but it does not seem to be able to open the VB5 project files. Any suggestions as to how to open the source files (.frm, .vbp, .bas, etc.) and edit them and recompile an executable? Thanks.
