BINGO !!!

That did the trick. I *knew* there was a simple way to do this.

Many thanks, Fabio...VERY useful.


>>Hi folks,

>>Okay, this one's driving me absolutely nucking futs today.

>>I have a specialized ADO-populated ComboBox, to which I've added (and populated with a default value) a property called icDataLinkFileName to hold the name of the UDL file (if any) which is used by the data handler to populate the control.
>>
>>Now, in one of the methods of this control, I need to check if this property has been changed in the particular *instance* of the control (ie, when the developer dropped the control onto the form/container, they decided to set the property to something other than its default value). Should be a breeze, right? WROOONG...

>>I've tried the following, all with no luck:
>>a) SYS( 1269, THIS, "icDataLinkFileName", 0 ) always returns false
>>b) PEMSTATUS( THIS, "icDataLinkFileName", 0 ) always returns false
>>c) PEMSTATUS( THIS, "icDataLinkFileName", 4 ) always returns true
>>d) PEMSTATUS( THIS, "icDataLinkFileName", 6 ) always returns true
>>
>>All the UDL files exist, in the correct location. When I change it in the property sheet, for either the class or the instance, the correct value is there. BUT IT WON'T TELL ME THAT IT'S BEEN CHANGED FROM THE DEFAULT.

>>This *CAN'T BE THAT DIFFICULT* !!!! What stupid, idiotically simple since-VFP-was-invented function am I overlooking here???
