Re: Error transferring internal Bitmap using BitBlt

Post by Narcís » Wed Dec 01, 2010 9:54 am

Hello everyone,

I have continued testing this issue and can't reproduce it consistently, it's somewhat random. Do you know of a consistent way to reproduce it?

Hein, did this occur using Remote Desktop at your end as well?

Thanks in advance.

Hello Narcís
i can reproduce the error if the remote desktop window is minimized and the program is showed normal. If this remote desktop window is in normal window state the error didn't happen. And if the program is minimized on the remote desktop and if the remote desktop is minimized, the error does not happen, too.

Your sincerely

Willi

Hi Willi,

Thanks for the info. Definitely minimizing the Remote Desktop window was the clue. I'll continue investigating.

Hi Willi,

This assertion was added for debugging some other issues so you can either compile your projects referencing TeeChart sources and disabling assertions at Project -> Optinons -> Delphi Compiler -> Compiling -> Debugging -> Assertions or directly remove the assertion from the sources. We are considering a definitive solution here as well.

Hello, Narcís.

I can reproduce this error if i switch windows user, when test application (or mine) is running.
I hope that it will be the helpful information:

Call BitBlt (in TTeeCanvas3D.TransferBitmap in TeCanvas.pas) gives
error code = 6 = Invalid descriptor (use GetLastError, FormatMessage).
Error code equals 6 in both methods of reproducing this error (remote access, switch user).

Best Regards

Constantin

Hi Constantin,

I could not reproduce the issue here doing as you reported with the test application. Does this occur with Remote Desktop too or directly working on the machine and just switching users? Does this occur with any specific Delphi version?

Thanks in advance.

Hi Narcis

I use Embarcadero® Delphi® 2010 Version 14.0.3593.25826 and
Hein Gustavsen's example (TeeChartBitBltError).
This error occurs with Remote Desktop too and
and just switching users too?

But in My Program this error occurs directly working on the machine
(without Remote Desktop too and and switching users too), very seldom.
My Project is built by Delphi7 with the same version
TeeChart (TeeChart Pro v2010 Build 2010.01.11004).

I use extended example of TeeChartBitBltError, which writes
call stack by the error (I use JEDI Code Library).
I attach this call stack and extended test project.
I hope, this information will help fix this error.

Best regards, Constantin

My Project is built by Delphi7 with the same version
TeeChart (TeeChart Pro v2010 Build 2010.01.11004).
Thanks for the info but I can't still reproduce the problem here switching users. If you can find a consistent way to do so we would be interested in knowing about that.
I use extended example of TeeChartBitBltError, which writes
call stack by the error (I use JEDI Code Library).
I attach this call stack and extended test project.
I hope, this information will help fix this error.
If you could attach this information here we could check if it coincides with what has already been discussed in this thread.

Thanks in advance.

Hi Narcís

I attach example, about which it was told in the last post.
I modified slightly file TeCanvas that the error registered in log.txt.
Modified file is attached also (it is in the project).

Best Regards,
Constantin.

Hi Constantin,

Thanks for the example project. I could finally reproduce the issue here just switching users but I didn't use your modified TeCanvas.pas as it is very different from the version included with v2010.02.20202. I had to remove JCL* components too. Anyway, I have updated the information at TV52015296, we will continue investigating the issue.

Hi Narcís

I can not understand why You can not reproduce this errir by switching windows user.
I propose you run test application, which is built on my computer.
I want to test: Does it depends on version of Delphi.
I attach test application splitted into 2 parts (maximum size = 512kb).
You can uppack it using WinRAR.
This test application is built on Embarcadero® Delphi® 2010 Version 14.0.3593.25826,
using TeeChart Pro 2010 02 20202 (without modidfications).
This test application writes error into file "Log.txt".

Best Regards, Constantin

Hi Constantin,

I'd like to apologise if my previous reply was not clear enough. I COULD reproduce the problem here quite easily switching users. Actually what I wrote in my previous reply is:

Anyway, thanks for your feedback and interest on helping us reproducing the issue. We will continue investigating it with the new information you provided.
