Hello,

Completely new to VB6, I have been developing with excel vba for several years. I created a simple calculator in VB6, and the error handling as my VBA knowledge transfered straight over pretty much.

I took the option Make Calculator.exe and no real problems, I know have a simple payment calculator that works perfectly on my XP machine. I burnt the exe onto cd and took it to another pc running windows 98 and it loaded up ok, but crashed instantly i tried to do anything.

How do I make my program backwards compatiable?

thanks,
Paul

Does your porgram load at all on the 98 machine, or does an error message pop up instantly?

my guess is that since you made the program on you XP machine, using vb, you have all the necesary file needed to run it, obviously. but then when you moved it to the 98 machine, it either doesnt have, or cant find those necesary files and thus, the program crashes.
a visual basic EXE needs certain file to run properly, sometimes, you may get lucky and those files are already on the computer you want to run the program on, and other times (often when using non-standard control, but not always) it wont have those files, causing an error.

you might try making an install file for your program, either using visual basic's "package and development wizard", or another install file maker of your choice.

You should make a setup package (with the Package&Deployment Wizard or a third party program) for your application instead of just copying the exe, and make sure you include the VB runtime files. Windows 98 comes with the runtime files for VB5, not VB6.
