By the way I messed up my project by adding and deleting a dialog and rename the new with the old one. can't open class wizard and keeps on prompting to locate the source even though I set selected it already

thanks Zac I'll try that.

For the SpinButton yes it's working, problem is It allows values outside the range thru keyboard input thanks

I'm just a beginner. I can set the range of SpinButtn but don't know how to deny values outside Min and Max thru keyboard input w/o using messsage box
