Estimado Leandro,

El Sr. Rao lo está revisando

El error viene de aqui:
oCol := ::aCols[ ATail( ::aDisplay ) ]

Parece que ATail( ::aDisplay ) esta devolviendo nil

Override Method MouseWheel In Class TXBrowse With XBr_MWhl

... lines than yours. Anyhow, the error that you get comes from TEXPLORERBAR:CHECKSCROLL() and the only place where nTop is used is here: oLastItem = ATail( ::aPanels ) ... oLastItem:nTop so it seems as oLastItem is nil. If you could post a screenshot of your explorerBar then it may be easier to spot ...

Tried with Clipper: same error. Ok, I'm going to change my source code...

Unfortunately, I can't test it with Clipper. Can you?

Thank you.

Dear Enrico,

I just reported it into the Harbour's developers group:

https://groups.google.com/g/harbour-devel/c/ZPvgH-Lt1sY/m/w5z0BUQSAgAJ

many thanks for your great feedback

It has not been corrected as lastest commit was on Apr 28, 2021:

https://github.com/harbour/core/commits/master

Sorry, I'm not following Harbour development. I don't even know if this bug has been corrected in the latest version.

Dear Enrico, Harbour and xHarbour source code for ATail() are the same, so we need to keep searching where the difference comes from. I would say that the compiler parser does not allows it, so we need to modify Harbour syntax rules. You should report ...

I forgot to mention that this works fine using xHarbour:

Code: Select all  Expand view

ATAIL( aArray ) = xValue

EMG

From Clipper docs: ATAIL() Return the highest numbered element of an array ÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄ Syntax ATAIL(<aArray>) --> Element Arguments <aArray> is the array. ...

Dear Enrico,

You can not assign a value to a value, so it seems as the error is correct. It is like doing:

nil = nil

Anyhow, if the returned value is an object with a redefined "=" or ":=" operator, then it should accept it

This is a sample of the problem: FUNCTION MAIN()    LOCAL aArray[ 10 ]    ATAIL( aArray ) = 123    ? aArray[ 10 ]    INKEY( 0 )    RETURN NIL I get Harbour 3.2.0dev (r2104281802)Copyright (c) 1999-2021, https://harbour.github.io/BUG.prg(5) ...
