Hello,

I have these codes, concerning bitmaps:


In both cases, the first lines results in a ".T.", which means that the file exist.
But in the second lines, the bitmaps don't appear on my screen. The button in the second case is working fine though.

It becomes more strange. Until now the problem only occurs if I use my application through Terminal Services on a Windows 2003 Server. The problem doesn't happen on a workstation until now.

I use FWH 9.04 and xHarbour Builder April 2009.

What is the reason for this problem ? Memory ?

Thanks a lot in advance for any help.

In my Applications I don't work with ..\, because sometimes a file was not found.
Maybe in Your different situations, the BMP wasn't found.
On top of my Application, I define the Procect-path.

c_dir := GetModuleFilename(GetInstance(),"MYAPPLICATION.EXE" + CHR(0), 255)
c_path := left ( c_dir, rat( "\", c_dir) -1 )

That allways works :
myfile := c_path + "\FWHVERS.MEM"
myBMP := c_path + "\IMAGES\MyBMP.bmp"

Maybe it helps.

Regards
Uwe

Uwe,

Thanks a lot for your help.

But I'm afraid that the cause of the problem is not to be found in the place of the bitmap.

As you can see in my example, I test the existance of the bitmap which always results into ".T.".

I use this function already for 10 years and I never had any problem.

Any idea ?

Antonio,

Do you have any idea why this problem occurs ?

Thanks.

Hello,
we also have 2 reports about disappearing bitmaps (TBtnBmp) after FWH and XHb upgrade but with bitmaps linked in from resource file. One of them on TS.

Customer's IT support was able to get bitmaps appearing after switching 16-bit colors to 32-bit in workstation Screen properties.

Can You check Your video card Color quality settings?

Best,
Taavi.

Code (fw): Select all Collapse

MsgLogo("..\BITMAPS\JUDA.BMP",5)

Code (fw): Select all Collapse

MsgInfo(FILE("..\BITMAPS\CURRENT.BMP"))
DEFINE BUTTON OF oBAR FILE "..\BITMAPS\CURRENT.BMP" ACTION (EditDos("Update",1,.F.))

In both cases, the first lines results in a ".T.", which means that the file exist.

Taavi,

Thanks a lot for your suggestion.

But I'm afraid that this is not the reason for my problem.

Meanwhile, I recompiled my application with FWH 9.03 and xHarbour Builder April 2009 and everything is OK now.

So, to my simple mind, the reason must be somewhere inside FWH 9.04.

Michel,

Could you please email me JUDA.BMP ? thanks

Antonio,

I'll send you "JUDA.BMP" and "CURRENT.BMP" by e-mail.

Thanks.

Michel,

We are going to review them.

In the meantime, would you mind to add this function to your main PRG and test it again ? thanks

Hi,
in our tests setting desktop color quality to 16-bit makes bitmaps disappear with FWH 9.04.

Taavi,

We found what is going on:

HasAlpha() is failing under 16 bits colors resolution and is returning a wrong value, so they get managed as alpha bitmaps when they aren't.

We need to detect if we are under 16 bits colors and return false. We are working to improve HasAlpha() for this case.

In the meantime, please add this function to your main PRG. It should solve the problem:

Taavi, Michel,

We have just published a new FWH 9.04 build that provides an improved function HasAlpha().

Please download it. We appreciate your feedback, thanks

Antonio,

Thanks a lot for your efforts.

I'll do the download followed by the necessary tests.

I'll let you know the results here.

Thanks.

Antonio, Taavi,

GOOD NEWS.

The problem seems to be solved. My bitmaps are shown again.

Thank you very much for your efforts.

Antonio, until now no problems with the TGET-class.

Thanks.

Michel,

Glad to know it is working fine

Many thanks for your feedback
