Hello,

I've installed "TeeChart Vcl 2010.01.11004 Professional" for "Delphi 2007 Professional". OS is Windows XP Pro.

Here's the problem:
- Create a new Vcl Forms Application.
- Put a TChart3D on the form.
- DoubleClick on the chart to show the Chart Editor
- Without changing anything, just click on de Close button of the Chart Editor.
- Delphi is gone/crashed.

Does anyone experienced this behaviour before? And does somebody knows the problem/solution?

Kind regards,

Invers

Hello,

Yes, I can confirm that also, just repeated your steps and IDE closed without any message

Regards

Hi,

I'm trying to reproduce it but I can follow your steps without having any problem.

Same problem here.

Hello,

We added it to the defect list to be investigated for further releases (TV52015320), although we didn't find a consistent way to reproduce it. The same process reproduces the problem in some machines with D2007, RAD 2010 and XE but in other machines.

I compiled a sample application with one TChart3D component and activated EurekaLog. http://www.eurekalog.com/index_delphi.php
In EurekaLog I activated the Anti-Freeze Option.
When this option fires in EurekaLog, the following Call Stack is shown:
C:\Windows\System32\glu32.dll

After recompiling TeeChart with debug info:

Hi Bert,

Thanks for the information. I have added it to the bug report.

If I copy TeeGLCanvas.pas to my project and compile it with assertions, the following exception is raised:

'ActivateContext (C:\ ...\TeeGLCanvas.pas, line 1460)'.

Everest (now Aida64) is a tool that shows a lot of information about the PC and the software. It says the following about OpenGL support in my PC.
My PC is a HP machine with Intel integrated graphics, so not state of the art.
I have ran the executable on 2 other PC's with old/integrated graphics and they have the same problem. On a newer machine with a recent Radeon card the application runs. This PC/graphics card has OpenGL 3.3 support.

Hello Bert,

We appreciate your feedback and investigation on this. It could be important information to find out what's exactly happening and how to solve it.
I've added your comments to the bug report.

I have checked a few PC's and a laptop with the test application.

Good:
RADEON 9250 - OpenGL 1.3 (XP)
RADEON X1650 - OpenGL 2.1 (XP)
RADEON HD 4770 - OpenGL 3.3 (7)

Bad:
Matrox G450 - OpenGL 1.1 (XP)
Intel 945G - OpenGL 1.4 (7)
Intel GMA 3100 - OpenGL 1.4 (Vista)
ATI Mobility RADEON 9700 - OpenGL 1.5 (XP)

Do you now the Delphi OpenGL Community? http://www.delphigl.com It seems they are very active with and knowledgeable about OpenGL. I downloaded one of the applications that is using their stuff and it runs fine on the laptop, where TeeChart isn't.
I tried to replace OpenGL2.pas with dglOpenGL.pas but couldn't get my application compiled. For someone with more knowledge it might be an easy change. It might be worth investigating.

Hello Bert,

Thank you so much again for the huge testing work you are doing here.

Hello,

I was wondering if any progress has been made with this issue. It has been open for almost 6 months now.
Were you able to reproduce it on your side, or do you have a test application with extensive logging that I and others can run?

Bert

Hello Bert B.,

This is a high-priority issue. I am sorry but bug with number (TV52015320) isn't still fixed. I recommend you to be aware at this forum, our RSS news feed, twitter and facebook accounts for new release announcements and what's implemented on them.

Thanks,
