I support an old software product that resides on a windows 98 computer.
This application is written in VB4 16 bit version. The program all of a sudden (my clients swear they did nothing to the computer) started working incorrectly. The problem is that when the program is run the icon appears in the task bar but the window does not show up on the screen. If you click on the taskbar icon it does not open up on top. The program doesn't seem to work correctly and I can't figure out why.
I have reloaded VB4 and have re-booted the program. No change. I re-compiled the code into a new executable and it had no affect.
I have run into this problem twice before (the same program runs in 4 different facilities) and reloading VB and/or recompiling has solved the problem.
I am assuming there is some old DLL or 16 bit way of doing things that is getting stepped on by some newer software but I do not know enough about what is going on to be able to solve this myself.
Any ideas would be greatly appreciated.
