Error in DCBrowse (solved)

[Tom]

No, only with 1.9 SL 1.

No, only with 1.9 SL 1

The Xbp_Brw.prg source from build 255 (SL1) does not match the error info you are getting.
This makes me believe that Alaska Software made a change in one of their patches but did not supply us with the source code for that change.

I suggest that you do the following:

Copy the build 255 source code: C:\ALASKA\xppw3219_sl1\source\SYS\Source\UI\BROWSE\xbp_brw.prg

to

\exp20\source\dclipx

Add the XBP_BRW.PRG to DCLIPX_19_SL1.XPJ

Rebuild DCLIPX.DLL by running BUILD19_SL1.BAT

My guess is your error will go away.

Hello Roger,
thank you for your tips.
I think i will force the update to XBase++ 2.0, for Tom says that he has seen this error only with 1.9 SL1.
My app have crashes with version 2.0, they are related to my outlook access to appointments, but with the help of Alaska we could eleminate this crashes with proper destroying (right order) of the used objects.

Hello Roger,
i now test my program compiled with XBase++ 2.0.1176 and eXPress++ V. 266 at a customer and the error with the DCBOWSE is arrising again:

Can you give me some code that creates the error?

[Wolfgang Ciriack]

I will try to extract some code from my program tomorrow.

[Wolfgang Ciriack]

Hello Roger,
have you received my mail ?

[Wolfgang Ciriack]

Hello Roger,
i have to come back to this item, because i still get these errors sometimes from my customers with version 2.00.1487 and eXPress version 266.
Alaska wrote me, that the sources of XbpBrowse are still delivered, they are in
c:\users\..your user..\documents\xbase++\source\runtime\dui.
Here is one error as an example, it is always the same, only with other parameters, f.e. {19, 7}, {7, 7} or {12, 1}

In the source (xbp-browse.prg) i see this line:

Code: Select all

METHOD XbpBrowse:GotoItem( nRow, nCol, lDehilite )
    LOCAL lIsMarked

    DEFAULT lDehilite TO FALSE

    lIsMarked := (nRow == ::nRowPos) .AND. ;
                 (::NavigationMode == XBPBRW_NAVIGATION_1XCOMPATIBLE .OR.;
                  AScan(::aRecNo, ::RowPhyPos) == nRow)    <-------------row 2411

If you need some sources (a ready to compile example is difficult to build), i can send them to you by mail.

This is a timing error. It happens in some browses if the users click very, very fast. We created a workaround.

[Wolfgang Ciriack]

Hello Tom,
can you tell me more, how the workaround works and where to put it ?
