Hello,

I am using RAD Studio 2007 and a VCL.NET application and
I upgraded from Teechart Pro 8.02 to 8.04.
Now, when viewing a chart I get an index error.

A right mouse click on the chart shows 'Teechart Pro v8.04.11395 Win32'.
But it should be the .NET version!
Why this?
How can I easily change this?

Thanks and regards
Reinhard

'Index was out of range. It must niozt be negativ or less than the list.
Parameter name: index.

Please help.

Thank you and regards

Hello,

Just a Test:
I create a new vcl.net project.
I add a tchart component.
I want to add a serie.
Then an error message occurs:
'bds: the index was out of range'

Please help.

Hi Reinhard,

Yes, you are right. It seems that there is a problem with the series gallery window that don't allow you to add series at designtime. I've added it to the wish list as a high priority (TV52013884) to be fixed as soon as possible.

On the other hand, please, could you verify and delete the old references at Components/Installed NET Components.../Assembly Search Paths?

Hi Yeray,

as you can see, the problem occurs in VCL.NET with TLineSeries and TPointSeries.
Is there any workaround possible?

Regards, Reinhard

Hi Reinhard,

The only thing I can recommend for now is to create your series at runtime and disable any user access to the series' gallery if enabled.

Hi,

sorry, but creating the series at runtime gives the same problem
(Index error) when showing the form!

Series_m0 := TPointSeries.Create( Self );
Series_m0.ParentChart := Chart1;

Please have a look at the newsgroups or change my test project to
creating TPointSeries at runtime.

regards,
Reinhard

Hi Reinhard,

I think you still could have old confusing references at your delphi's search path, library path and/or assembly path. Have you revised them?

The project you sent to us shows win32 at teechart's about that makes me think that this is not a vcl.net project. Do you create the project through File/New/VCL Forms Application - Delphi for .NET?

Your project shows me the series' gallery without errors at design time and crashes, as you say, when showing a populated series.

I've sent a simple VCL.NET project that creates a series and populates it at runtime to the mail account you used to send the project to us. Could you try to compile and run it?

Hi Yeras,

thank you for your help!
Nevertheless, I think it has something to do with the color.
Try:
//Series_m0.FillSampleValues(25);
Series_m0.addxy(1,2,'d',clGreen); // <--
Series_m0.addxy(4,5);
in your Simple_project and you will get the index error, sure.

Thanks and regards
Reinhard

Hi Reinhard,

Yes, you are right. It seems that there is happening something strange when drawing this chart because it crashes, as you said, when showing the form.

So, I've added it to the wish list (TV52013890) and we'll try to solve it as soon as possible.

Hi Reinhard,

Just wanted to let you know that the issue has been fixed for the next maintenance release.
