Error in DCBrowse (solved)

[Wolfgang Ciriack]

Hello Roger,
at some customers i still sometimes get this error in a DCBrowse which is heavily used. Mostly, in a network, if the response time is slow.
Do you have some idea, were this can come from ?
(I use version 266)

Please put an example of the code that can be compiled to help you

This is nothing that can be replicated with demo code. It's from normal browses, just DCBROWSE with some columns, and it doesn't happen often, but it happens. We also get this, and the reports we get come from different browses, different topologies, they have nothing in common.

The error is in the :gotoItem method of XbpBrowse.

Unfortunately, Alaska no longer gives us the source for that class.

I have the source from Xbase++ 1.9 (xbp_brw.prg), but there is nothing in the :gotoItem method that has a >= in the code so it's going to be difficult to figure out what Xbase++ has added to the code in version 2.0 that can cause this error.

The error is caused by comparing an array type to a numeric type.

I suggest that you send that error info to Alaska Software anyway.
They may have some ideas.

I'm surprised that Alaska does not supply Browse source anymore.
as i know it was always part of Pro Version so it is now incomplete ...

Hello Roger,
this error is still with XBase 1.9.

[rdonnay]

Search your Xbase++ 1.9 installation for Xbp_Brw.Prg.

Look at that line of code (1896).

I would like to see what that code is doing.

[Auge_Ohr]

this is in v1.9.355

Code: Select all

1891 METHOD XbpBrowse:GotoItem ( nRow, nCol, lDehilite )
1892
1893    DEFAULT lDehilite TO FALSE
1894
1895    // when the same item has been marked a second time, I will just return
1896    IF ( ::CursorMode == XBPBRW_CURSOR_ROW )

[rdonnay]

That source code doesn't match the error info.

[Wolfgang Ciriack]

In my file Xbp_Brw.Prg in the express\Source\Dclipx folder i get the same as Jimmy posted.

Code: Select all

    IF ( ::CursorMode == XBPBRW_CURSOR_ROW )
       IF nRow == ::RowPos

I think it is the row IF nRow == ::RowPos, so nRow seems to be an array ???

@Tom,
do you get these errors with 2.0 ?
