DCREAD VALID

Hi Roger,
Something recently observed
The DCGET VALID does not get called if paired with WHEN
Using xBase++ 1.90 355 and eXpress 1.9 257
\
Code: Select all
@ 1.00,24.00 DCGET nJudge Picture '9999' PARENT oGroup3a COLOR GRA_CLR_BLUE ;
TABSTOP ;
GETID "Get_nJudge" ;
WHEN {|| nJudge == 0 } ;
TABGROUP XBP_BEGIN_GROUP ;
VALID {|| ValidateJudge(nJudge, GetList) } ;
POPUP {|n| n := JudgeScan(nJudge, GetList) } ;
MESSAGE 'Enter The Hearing Officer ID Number to be Maintained.' INTO oMsgBox

Valid codeblocks do not get evaluated if the WHEN clause code block returns a .f.
I'm reluctant to change this behavior because it has been the default behavior in eXpress++ for 12 years.
It appears that you do not want JUDGE to be edited after the first time a value is entered.
I can't think of a simple solution.
What does the validation do?

Simply return the values for the record to be edited.
It appears that the WHEN functions if it is not the specific value of the DCGET as in the following example:
Code: Select all
@ 1.00,21.00 DCGET cCode Picture '@!' PARENT oGroup COLOR GRA_CLR_BLUE ;
TABSTOP ;
GETID "Get_cCode" ;
WHEN {|| nGroup == 1 } ;
TABGROUP XBP_BEGIN_GROUP ;
VALID {|| ValidateCode(cCode, cRecId, GetList) } ;
POPUP {|c| c := GuiCodeScan(c, cRecId, cText, GetList) } ;
MESSAGE 'Enter The ' + cText + ' Code To Be Maintained.' INTO oMsgBox
No problem, I can code around this.
How are the teeth feeling?
Thanks,
Rick

I'm feeling great! After 3 trips to Mexico in 3 years I now have a pretty good set of teeth.
We're having another devcon in AZ next year in October. Hope you will be there.

I would have liked to been there this year, but the time frame conflicted with other events.
While I certainly missed seeing those attending, I was uncertain of the benefit of attending except the social aspect of seeing old friends.
I really liked your eXpress Devcon in Boise because xBase is the car, but eXpress is what drives us.
Glad to hear and looking forward to seeing your smile.

This solved a problem I worked on for hours. I finally discovered a VALID was changing a variable in another GET and I didn't know how to prevent it. After I saw this topic I used WHEN{||.f.} in tandem with HIDE{||.t.} and it worked as I wanted.
Please don't change the way it works. Perhaps a VALIDWHEN parameter could be added instead.
It isn't always asking questions that make this forum so valuable to me. Thank you and everyone for all your input. I learn from every question.
