GET MEMO command error?

[dutch]

Dear Antonio,

I have used following code for normal GET. I work fine but when I use the same with MEMO field. It is not working and show this error.

Code: Select all  Expand view  RUN

*--------------------------------*
Procedure MakeGet(oGet,aMField,Nr,aStruct)
// aMField := {151,'TBL->TBL_MEMO'}
// aStruct := {{'TBL_MEMO','M',10,0}}
if aStruct[ascan( aStruct , {|x| x[1]=right(aMField[Nr,2],len(aMField[Nr,2])-5) } )][2] = 'M'

REDEFINE GET oGet[Nr] VAR &(MEMVAR->aMField[Nr,2]) ;   
               MEMO ;
               ID MEMVAR->aMField[Nr,1]
else
REDEFINE GET oGet[Nr] VAR &(MEMVAR->aMField[Nr,2]) ;   
               ID MEMVAR->aMField[Nr,1]
end
return


Code: Select all  Expand view  RUN

Dutch,

It looks like it is erroring out on this line of the Redefine method:

oWnd:DefControl( Self )

I think you need to add the OF oWnd clause.

TGet's oWnd defaults to GetWndDefault() but that is not really what you want either. TMultiGet doesn't have a default oWnd, thus the error. You should always specify the OF oWnd clause for all your controls.

Dear James,

You answer is the correct point, it works correctly.

Thanks&regards,

Dutch, James,

We have included DEFAULT oWnd := GetWndDefault() in Method Redefine() for next build, thanks!

Antonio,

I wonder if it wouldn't be better to let it error out? If it defaults to the wrong window as the parent it may even be harder to find the problem. What would the consequences be if it has the wrong parent window?

James,

A REDEFINE is always issued after a DEFINE DIALOG ..., and DEFINE DIALOG sets the default parent window.

Of course it is much better to specify OF oDlg, but if the programmer forgets it, FWH takes care of it.
