Re: VB program conversion from Windows 95 to Windows XP

Tech Tip: Click here to run a free scan for Windows Errors and optimize PC performance

I followed your suggestion and got into the old closet with a windows 95
system in it that could recompile my program. It still does compile and
built the same executable.
Then I tried to isolate the hundreds of possible errors that all funnel into
one. Executing this version of the 95 executable on XP led me to the same
problem as the compile on XP. It died in the initialization of the ADO
data-base, so I am back to square one.
Any further suggestions?
