Access Violation Steema Active x V8

Forgive the code example. its quick and dirty but shows the problem

TChart1.AddSeries (scFastLine)
TChart1.AddSeries (scFastLine)
TChart1.AddSeries (scFastLine)
TChart1.AddSeries (scFastLine)
TChart1.AddSeries (scFastLine)
TChart1.AddSeries (scFastLine)
TChart1.AddSeries (scFastLine)
TChart1.AddSeries (scFastLine)
TChart1.AddSeries (scFastLine)
TChart1.AddSeries (scFastLine)
TChart1.AddSeries (scFastLine)
TChart1.AddSeries (scFastLine)
TChart1.AddSeries (scFastLine)
TChart1.AddSeries (scFastLine)
TChart1.AddSeries (scFastLine)
TChart1.AddSeries (scFastLine)
TChart1.Legend.MaxNumRows = 2
TChart1.Legend.Alignment = laBottom
TChart1.Tools.Add (tcLegendScrollBar)

This will draw a simple graph with a legend max rows of 2. The problem occurs when you try and scroll the legend scrollbar. when you reach the right hand side the OCX crashes with an access Violation.

Is this a known problem ? or am I being daft ?

Hi ar,

Thanks for reporting. I've been able to reproduce the issue here and it's certainly a bug which I've already added to our defect list as a high priority issue (TV52012755) to be fixed for next releases.

Narcis,

Thanks for the reply. Is there any timescale for the fix as the functionality is critical for this part of our product ?

Without a fix I am going to have to revert to 7.0 and I would rather stay with version 8.0.

Hi ar,

I'm sorry to hear that but at the moment I can't give you an estimate date for this fix. As I already told you, it's a high priority item in the bug list but that's all I can say at the present moment.

The same bug appears to be present in the latest version of TeeChart 7 Active X as well.

Reverting to 7.0.0.4 clears the problem. I dont have any OCX versions beyond this revision to test when the problem was introduced.

Hi ar,

Thanks for the information. This may help us finding where the problem was introduced.

Is there an archive of Version 7 Installers anywhere. I would like to use the latest version 7 that I can, however on the customer download area I can only seem to download the latest version.

Hello ar,

I've sent you an e-mail with previous ActiveX versions.

BTW: Have you tried using v8.0.0.3 which was posted by the end of last week?

8.0.0.3 exhibits the same bug. I just tried it.
