My user control has diagonal lines thru it

I created a user control called ucDateTime that consists of a DTPicker and 3 command buttons; Clear, Quit and Set. I have a textbox on a form called txtDate that is populated with a date and time. When the user clicks on the textbox, it becomes invisible and the ucDateTime control becomes visible in its place and populated by its value(Now if it is blank). The user can click Clear to remove the date and leave txtDate blank, Quit to leave txtDate as it was or they can select a date/time and click Set to move the value to txtDate. I haven't worked out all the bugs yet but I'm close. When I stop the app and return to the form design, the user control has diagonal lines thru it. Can someone tell me what that is and how I might correct it?

Thanks,

Greg

The UI is dead 'cos the control has an error or has changed and not been rebuilt since the last change.
Double click of the UserControl in the project explorer to open it and, if no error message, close it again...that should clear it?

MerrionComputin,

What you suggested cleared the lines but when I ran the app, exitted the app and returned to form design, the lines were back.

Odd...
Make sure the UserControl window is closed before running any app that has forms that reference the control.
Other than that, I'm out of ideas...

The diagonal lines that you get are due to an error that occured in your activeX control.

Usually when you get an error in your code, your app will raise a type mismatch error, but in a compiled activeX control you won't get that message, you will only get those dreaded diagonal lines.

I would suggest that you step through your code of the active X control and I'm sure you'll find that somewhere you used a variable that creates a type mismatch error. Eg: msgbox cdate(dtMyDate) ' where my dtMydate is a string variable that contains a value that can not be converted to a date.

I hope this helps.
Cheers
