COMException Error

Dear Team,

I am getting an error so called "System.Runtime.InteropServices.COMException (0x8000FFFF): Schwerwiegender Fehler (means Serious error)" after adding 289000 data points by AxTChart1.Series(3).AddXY. But it happens only in one of the several series and it is assigned in custom axis in vertical. But then I uploaded same amount of data through AxTChart1.Series(3).AddArray and then used AxTChart1.Series(3).AddXY and it work fine.

Its also in VB.Net 2003

Any solution for the above?

Ajith

Hi Ajith,

Could you please send us a simple example project we can run "as-is" to reproduce the problem here? You can either post your files at news://www.steema.net/steema.public.attachments newsgroup or at our upload page.

Thanks in advance.

Hi Narcís,

Thanks for the reply.

since the module is very huge and its online measurement for a particular device, I may not able to upload data.

I will try some other options and get back to you.

B Regards
Ajith

Hi Ajith,

It would be enough for us if you could arrange a simple example project using random data that reproduces this issue.

Thanks in advance.

Hi Ajith,

Thanks for the newsgroup attachment but it is very difficult to see where the problem is with so little information and it being intermittent.

How do you populate your chart? You could try setting TChart1.AutoRepaint=false, add data to your chart and then set AutoRepaint to true again. A problem with custom axes could be another option.

If you find any consistent way to reproduce the problem please let us know.
