Hi Eric,

Ok, thanks. I got the .ten file. You can already remove .ten and .zip files from your server. I'll get back to you when I have some news.

Regarding the newsgroups, you just have to set up www.steema.net as a news server in your news reader using all default settings.

Hi Eric,

I was able to reproduce the problem you reported. However, it is very hard to guess which can be the problem without being able to load the .ten file. Could you please post the project, or an example we can run "as-is", showing us how is the chart (all properties you set) you exported to the .ten file?

Dear Sir/Madam

Can you please do me a favour? Can you please remove my company web site URL. Because I'm worry that our customer know that we have a problem in our chart component. THANK

I understand it will be diffcult for you to solve the bug without the sample program. But that is so funny, It work fine when we use the same setting in the testing program.

Anyway, We try to our best to give you a sample program asap and be side that we hope you can continue to find out the problem and solve it.

Thank & Best Regard's
Eric

Dear Sir/Madam

We try to make the same setting in our custom chart control and pure tchart control at the testing program. It work fine.

I'm guess maybe something wrong during I'm upgrade the Tchart version 1 to Tchart version 2.

1. Uninstall the TChart.net version 1
2. Install the TChart.net version 2
3. Open my custom chart control
4. Remove the tchart.dll (version 1)
5. add the new tchart.dll from the c:\program file\xxxxx\TeeChart for .NET v2\TChart.dll
6. Press build

It is correct step?

I'm really don't know how to give you the sample program.
But when you try to loading the test.ten file, I think you able to retrieve back the properties setting right?
By the way, do you checking the problem now?

... Please help. we got demo on next week web......

Dear Sir/Dadam

Finally I able to give you the sample test program

Step to occurs the bug.

1. Run the WindowsApplication2\bin\WindowsApplication2.exe
Note: Move your mouse arrow out of the screen
It work fine right?
2. Please remember the chart position show in the window application2.exe
3. Close the sample program
4. Move you mouse arrow in the chart position just now show in the sample program
5. Press enter key to run the sample program, Error occurs right.
Note: You must point your mouse error within the pie chart, else no error occurs.

Now you can open the source code to check it up.
The problem I guess is below the code.

PCYChart.Tools.Clear()
TChart.Tools.Add(New Steema.TeeChart.Tools.MarksTip)
TChart.Tools.Item(0).Active = True

When active the MarksTip = true and during loading the pie chart it will occurs the error.

Thank & Best Regard
Eric

This is correct but the most important thing is changing the .dll version on your project references section.

Finally I able to give you the sample test program
Please download below the test program. Again let me know when you get the sample program, I want to remove it from our web server....

Thanks for the example, you can remove it. I'll have a look and I'll get back to you when I have some news.
