Problems with xBrowse (last FWH release)

[Marco Turco]

Hi all,
there is a big problem using bitmaps into xBrowse using this last FWH release.
I have an array where I insert in the first element a number referred to the bitmap to use (1=red, 2=green...).
The first time I display the browse all appairs well but if I close the browse and try another time to display it appairs empty. All runs well using FWH April 2009.

A small self contained sample that show the problem (source and executable) is available at http://www.softwarexp.co.uk/beta/xtest.zip
Pls. run the executable, press Test/Show xbrowse (you'll see the xbrowse displayed well), then close the xbrowse dialog and press another time "Test/Show xbrowse" and the xbrowse will appairs empty.

Any ideas ? Is this a bug or I only need to change my code ?

Thanks in advance

Marco,

I don't know if this is the problem, but you have no RETURN statements at the end of your first two functions. Fix this and see if the problem goes away.

You always need a RETURN statement at the end of every function.

Hello James,
please try the xbrwtree.prg from the Fivewin - examples. If you scroll the icons are lost.
Best regards,

Hi,
I tried adding the Return statement and also changing the xbrowse class as suggested but it doesn't runs.
I think it could be a more complex problem in the FWH libs due to the fact that the problem still appairs also replacing in full the class xbrowse with the same class included in FWH April 2009.

Only rebuilding the self-contained sample with FWH April 2009 it runs well.

Only rebuilding the self-contained sample with FWH April 2009 it runs well.

Do you mean to say that it works well in FWH 9.04, but not in 9.07 even if we compile with 9.04 xbrowse?

[Marco Turco]

Yes.

This is the same prg compiled with FWH 9.04. As you can see it runs well.

If this can help to find the problem,
after the problem appairs in the xbrowse on my commercial app then the bitmaps hide also in the standard twbrowse.

Hi all,
Did anyone find a solution for this bug ?

Marco,

It is not a bug now. It was a bug on previous versions

If you move these lines from the top to here:

Code: Select all  Expand view

Function ShowBrowse()

    b_Red:=ReadBitmap(,"16red.bmp")
    b_Green:=ReadBitmap(,"16green.bmp")
    ...
 

then your example works fine. The reason is that Method AddBmpHandle( hBitmap ) of Class TXBrwColumn adds a new bitmap handle and now when the browse is destroyed it properly destroyes all the used bitmaps
