We are using TeeChart Pro 5.03 with Delphi 7. We have used TeeChart for years and for the first time we are using a chart with multiple custom
axes - and this is the first time we have experienced the 'scan line index
out of range' error.

In Byron Upchurch's post of 30 Dec 2004, he describes the same error. He goes on to say it was in Version 5.02 but was fixed in subsequent versions ... we have version 5.03 and it is still there. Does anyone know what causes this problem and what source code changes are required to fix it? We don't want to upgrade [so many compatibility problems with other component sets whenever we upgrade!] for what should be a trivial problem.

Thanks for any help.

Mike

Hi Mike,

I'm not sure what problem you refer, could you please post the link of the post you're referencing ?

Hi

I'm not sure how to do that ... in Outlook Express, looking at the newsgroup public.teechart5.delphi (www.berneda.com) it's dated 30/12/04 7:44 a.m., titled 'scan line index out of range', posted by Byron Upchurch.

The contents are below ... thanks.

Just as a follow up to this thread, I did submit a test executable directly
to Narcís.

The bug existed in TeeChart 5.02, but has been fixed in subsequent versions.
I upgraded to the latest version and found this to be true.

Hi,

could you please send me a simple demo with which I can reproduce the problem here and take a look which part of code has been modified in order to fix it ? I think this problem has been fixed in the TeeChart Pro v6.
You can send me the app. directly to pep@steema.com

I have emailed a small sample application [and source code] as requested. Thanks for your efforts.

Regards

Mike

I have started with a new PC [formatted hard disk and reinstalled operating system], installed Delphi 7 and updates, and downloaded and installed 5.03 from your website. The simple sample application I sent still raises the "scan line index out of range" exception.

If the problem has been fixed in 5.03, this doesn't make sense ...

Hi Mike,

We haven't been able to reproduce the problem you reported here. I've sent the .bpl files we have used for those test. Could you please test them to see if they work for you?

Hi Narcis

The zip file you sent only contains 6 BPL files. The version of TeeChart we use generates many more (12, I think) BPL files.

I copied the 6 BPL files in accordance with the normal installation instructions, i.e.,

Destination of compiled packages:
----------------------------------

\Program Files\Delphi (BCBuilder)\Bin:

DCLTeexx.bpl ( *.dpl in Delphi 3)
DCLTQRxx.bpl
DCLTePxx.bpl
DCLTGLxx.bpl

\Program Files\Delphi (BCBuilder)\Lib:

-All *.DCP, *.DCU, *.DFM, *.RES files.
-TeeDefs.inc file.

\Windows\System (\WinNT\System32) :

Teexx.bpl ( *.dpl in Delphi 3)
TeeDBxx.bpl
TeeUIxx.bpl
TeeGLxx.bpl
TeeQRxx.bpl
TeeProxx.bpl
TeeImagexx.bpl
TeeLanguagexx.bpl

I rebuilt the demo application I sent you and sadly it still raises the same exception. I have checked and there are no other occurrences of those BPLs on this PC.

Thanks for your continued support.

Regards

Mike

Hi Mike,

Yes, you are right, I missed some of them. I've just sent you the complete .bpl files.
