Visual Basic 6 applications
running under Windows Vista July 13, 2009
Recently,
while writing application code for a customer, my programmer spent days
working on the application because it ran well under XP, 2000, and for
a while, ran under Windows Vista.
All of a sudden, it quit
working under Vista with an error message "Unexpected Error" with no
other indication, nor the typical "quitting" message. After a
frustrating time, even to the point of eliminating all code except the
form itself, he discovered the cause of the error was the Icon used to
start the application.
The programmer had found an Icon which he
liked for this application, editted the Icon using Corel Photopaint 12
and converting it from a .PNG to a .ICO. When he eliminated the Icon,
the program started and ran successfully. He has not yet investigated
what is causing this to crash Windows Vista. I will update this page
when we know what to do.
If you have comments or suggestions, please e-mail me at the address
below, or give me a call.
After a little experimentation, he found that a converter called ICOFX
works well and can be located at http://www.icofx.ro
