Where I work we designed our application (VB5 and C++) and used long file names for our DLL’s and OCX’s. For some unexplained reason we had trouble with the files after registering them in the Registration Database. We switched to the old 8.3 file names and the problem went away.
I could not find any official information about this in the Microsoft Knowledgebase. But if you notice, all OCX’s and DLL’s put out by Microsoft use 8.3 file names… go figure.
