When using
myClass:Show()
WAIT-FOR System.Windows.Forms.Application:Run(myClass)
to run the appliction.it fires "Destructor" and deletes all the objects after closing the application.
However, it does not work the same way by using the Run method without a parameter (WAIT-FOR System.Windows.Forms.Application:Run()) and using Application:Exit() to terminate. if I explicitly delete object (myClass), all the UltraGridColumns are not removed. Please help.
This is known bug in the Progress 10.2B and Progress says that it has been fixed in 10.2B02 to be released later this year , perhaps in Sept-Oct 2010.
