Bug in TBar?

[ukservice]

Antonio,

I search into Manual and Wiki for function IsGdiObject() and it does not exist.

My PC has 8 GB of RAM, so I think it is not a question of memory (unless FWH does not manage 8 GB as it happened with nExtMem()).

Point 3 sounds very interesting. I await your instructions.

Thanks a lot.

Daniel,

How are Bmps painted in Ribbon?. Does Ribbon use TBar?.

How can I track painted bmps?.

Thanks.

Please add this code to your main PRG:

#pragma BEGINDUMP

#include <windows.h>

static void TransBmp( HBITMAP hBitmap, int iXsize, int iYsize,

Antonio,

It happened today in Ribbon but no messagebox appear!!!.

Is above TransBmp included in FW 11.11?.

Can you check it?.

Thanks.

[ukservice]

up

[ukservice]

Daniel?.

Any idea or clue?.

Thank you.

[Daniel Garcia-Gil]

Hello

i have not any error or bug with this class, can you provide a sample we can reproduce the problem...

thanks

[Enrico Maria Giordano]

Unfortunately not. It is very very random. Myself I didn't saw the problem anymore.

EMG

[ukservice]

Enrico, thanks for listening.

Daniel, is TransBmp´s funcion pasted above included in FW 11.11?.

Thank you.

[Antonio Linares]

John,

yes, it is but without the MessageBox() calls

[ukservice]

Antonio,

I need please latest source with MessageBox in order to trace the bug.

Where should I put the code?.

Thanks.

[Antonio Linares]

John,

If you include that code in one of your own PRGs, your function will be used instead of FWH one

[ukservice]

Antonio,

Done.

I also added a number to each message to trace the error:

Form this .c code, how could I invoke Fivewin´s error system to generate an error.log file with all the debug info to trace this bug?.

[ukservice]

Antonio,

I was able to trace the error.

Most of the buttons of the ribbon where painted, but in one case I got:

Error (2) Can't create bitmap!. Please, see above code to see error numbers.
