SET TEXTMERGE TO MEMVAR not working

[wgcs]

I haven't been able to determine the circumstances, but when called, the SerializeObject function in thread184-805859 doesn't change the Textmerge'd memvar at all, thereby returning .F.

Does anyone know of what circumstances might cause the "SET TEXTMERGE TO MEMVAR lcOut" to not work?

 

[wgcs]

Found the problem. In the help on TRY..CATCH, it says:
Avoid using the SET TEXTMERGE TO MEMVAR command within a TRY...CATCH...FINALLY structure because the memory variable will be lost if an error occurs in the statement.

Now, I really expected that meant not to SET TEXTMERGE TO MEMVAR inside the TRY..CATCH..FINALLY, but I found that if an exception is caught, the SET TEXTMERGE is un-done, even though the SET TEXTMERGE started before the TRY.

I don't like it....

(ps: Anyone know where to submit suggestions on improving the VFP help file??)

I looked back, and noticed that I didn't even have the TRY..CATCH processing in the Serialize code in the Thread184-805859.

I had added it around:

    lvData = EVALUATE('toObj.'+lcProp)

so that it became (the red is what I added to solve the problem described above):

  lvData = 'Error Serializing'
  TRY
    lvData = EVALUATE('toObj.'+lcProp)
  CATCH TO oExc
    lvData = 'Error Serializing'
    * Ignore Error
    [COLOR=red]* fix the SET TEXTMERGE that was un-done by CATCH
    SET TEXTMERGE TO MEMVAR m.lcOut ADDITIVE[/color]
  ENDTRY
  IF VARTYPE(lvData)='C' AND lvData=='Error Serializing'
    LOOP
  ENDIF
