Antonio,

Dear Silvio,

We tested this example and it works fine:

Code: Select all

#include "fivewin.ch"

function Main()

  XBROWSER "CUSTOMER.DBF" COLUMNS "FIRST","LAST","CITY"

return nil

Mr. Silvio

Are you sure you are not using a modified "rpreview.prg" in your application?

After a detailed examination we could not see any reason why "::oZoom" can be NIL in line 1206.

Please build the above sample posted by Mr. Antonio, in the samples folder with buildh.bat and try if you get this error and let us know.

I must revise that app, I notice you if I see also the error

We checked thoroughly.
There is no way anybody can get this error unless he is using an incorrectly modified rpreview.prg.
There is no problem with the rpreview.prg as exists in the fwh library.

Mr. Rao,
The other day I recompiled a source with the new Fwh (20.12)
and this error came out and since it seemed strange to me I asked on the forum.
Then I deleted all the objs that are created in the obj folder (I use xmate to compile), recompiled and that error never came up.
I not link any rpreview revised but only the fwh lib
in the past when rpreview did not work I had created some override functions, but in that application I do not use any other rpreview except that of fivewin

[nageswaragunupudi]

recompiled and that error never came up.

Ok. good to know.
