Upgrade Teechart v7 from v5

[dmisland]

Hi

I upgraded from the Teechart that came with Delphi 7 to v7 PRO with source.

When I try to run an application designed with v5, I get two error messages:
[1] Property Pages does not exist
and then
[2] Error reading chart2.Pages.ScaleLastPage: Property Pages does not exist

Because there are a lot of designtime configurations for the tcharts in the application, including many tchartseries, I do not want to have delete, add and reconfigure those tchart components.

How can I get past this problem?

Thanks,
David

Hi David,

please take a look this post, it's referecing to the same problem.
It's for Delphi6 but all except the rtl updates can be checked.

Thanks for your reply.

As with the previous post to which you referred, I had already made sure all v5 files were removed. As you say, the v7 install did most of that. I am not using the "build with runtime packages" option.

I can design and run a new application that uses teechart v7, without any problem.

I know that I could go to the trouble of deleting the TChart components in my teechart v5-compiled application, adding the components back, and then re-configuring them. But that is just so much work!

Any other ideas?

Thanks,
Dave

Hi Dave,

does this problem happens using the TeeChart pro components on a new application ?

With a new application, there is no problem.

I finally simply deleted the TChart component from my older application, added it again, and reconfigured it. It took me a lot of time, but there didn't seem to be any other option. Now everything works fine.

The strange thing is that only one TChart component in that application caused the problem. The others worked fine, even though I deleted all application DCU files and the EXE, and rebuilt/compiled.
