>>Hi Everyone,
>>
>>I am using Microsoft´s Common Dialog activeX control to select printer settings before issueing a report. It seems to be that the CancelError property if set to .T., generates Error # 32755 if user selects Cancel command button, while in the printer properties dialog. In order to trap the error I wrote the following code:
>>

>>	On Error Do ErrHand
>>	thisform.oleMSCommonDialog.CancelError=.T.
>>	thisform.oleMSCommonDialog.ShowPrinter
>>	On Error
>>	thisform.oleCrystal.Destination=0
>>	thisform.oleCrystal.ReportFilename=cPath+'visitas.rpt'
>>	thisform.oleCrystal.PrintReport
>>	
>>For debugging purposes ErrHand is a PRG with the following code:
>>
>>	Procedure ErrHand
>>		wait window "Error 32755 has occured"
>>	Return
>>
>>

>>ErrHand routine is not being called, even if exiting Printer dialog with cancel button, that is, error message above is not displayed.
>>
>>How can I trap the error or cancel printing if user presses the cancel button ?

>Hmmm. If I set up an ON ERROR command, it works OK for me. Do you have some other kind of error handling for this form? It worked in both VFP5 & 6 both have their respective SP3's applied.

I also ran my test by bringing up the Printer Dialog from a command button. If you put error code there, it seems to work, too.

Code in the button Click event:
this.Parent.oleControl1.CancelError = .t.
this.Parent.oleControl1.ShowPrinter()

Code in the button Error event:
LPARAMETERS nError, cMethod, nLine
MessageBox('Error! '+STR(nError)+' '+cMethod+' '+STR(nLine))

It returned error 1429 in for my buttons Click event, line 2, the ShowPrinter call.
