GPF Error - Stack Overflow

Mensaje por g.s.rogers »

I am putting the following code in the OnChange event of a DBBrowse object:
cSeekVal := "CCIVIL " + ::oDbfDataSetCCivil:IdNo
::oDbfDataSetPlaintiffs:SetScope( cSeekVal, cSeekVal, .T., .T. )
When I run the project, I get the following GPF:
#1: GPF (Code = c00000fd):
Stack overflow
TFOLDER:GETFONT (0)
TFOLDERPAGE:GETFONT (456)
TPANEL:GETFONT (456)
TDBBROWSE:GETFONT (456)
TDBBRWCOLUMN:OFONT (456)
TDBBRWCOLUMN:PAINTDATA (105)
TDBBROWSE:DRAWLINE (265)
TDBFDATASET:CHANGEPOS (1276)
TDBFDATASET:GOTOP (402)
TDBFDATASET:SETSCOPE (1359)
FORM_CCIVILCASES:DBBROWSEPLAINTIFFSCHANGE (2145)
TDBBROWSE:ONCHANGE (0)
TDBBROWSE:DSNAVIGATE (650)
TDBFDATASET:UPDATECONTROLS (1211)
TDBFDATASET:GOTOP (408)
TDBFDATASET:SETSCOPE (1359)
FORM_CCIVILCASES:DBBROWSEPLAINTIFFSCHANGE (2145)
TDBBROWSE:ONCHANGE (0)
TDBBROWSE:DSNAVIGATE (650)
TDBFDATASET:UPDATECONTROLS (1211)
This code is running on a Vista Business operating system.
Any clues as to what is going on? This same scope statement works in the
OnCreate() event.
TIA,
Gary

Gary,
As you can see is a problem of recursivity:
> FORM_CCIVILCASES:DBBROWSEPLAINTIFFSCHANGE (2145)
> FORM_CCIVILCASES:DBBROWSEPLAINTIFFSCHANGE (2145)
The OnChange event is called again before its code execution is finished.
Review your code to see what is provoking that second execution.
On sample datacontrolsDbfData6FrmFacturas.prg we do exactly the same code
with no problem at all.
Regards,
