Delphi 2006 and TChart 7.06 not working directly

mtspp · Post by **mtspp** » Wed Mar 01, 2006 2:06 pm

I have a suspicious problem with Delphi 2006 and TChart 7.06

I habe Delphi 7 and Delphi 2006 installed on my system. Delphi 7 and TChart 7.06 is working fine.

When I try to work with Delphi 2006 and TChart 7.06 I can place a Chart on my Form, I can configure the form and I can compile and save my project. But when I close Delphi 2006 and restart it and open my project again I´m no more able to configure anything at the TChart. When I click at the chart I get a TForm.ChartClick Event created in my code.

The only way to get it working back again is to close my project, open a new project, add a TChart, close this again and reopen my originla project. Then the TChart is working as it should.

So it seems to me Delphi is loading something when I add a chart which is not laoded when I only open my saved project.

I already tried to delete all old TChart Files, because Delphi 2006 comes with a simple version of TChart.

So can sb. please tell me what I can do to get my TChart working as ist should with Delphi 2006?

Regards

Hi mtspp,

When you have the TeeChart v7.06 project working you could try openning Project\Options, select the left-bottom "Default" checkbox and press "Ok" button. This will make that the packages and search paths that work for TeeChart as set as a default to any other packages.

Hi Narcis,

I tried it but this is also not working, I still have the same behaviour. When I add a Chart it is working. When I save the project and restart Delphi 2006 I can open the project, the Chart is still visible but I can not do anything. I first have to add a new chart the it is working again.

Hi again,

maybe I found the problem but I don´t know how to solve it ;-(

I found TeeChart files in system32 named *tee100*.*, I think they come with Delphi 2006. I deleted them, but when I open Delphi 2006 and add a Chart and compile the project Delphi automatically starts the installer and wants the CD1 and 2 from Delphi 2006. When I search again after that installer the files *tee100*.* are back again in system32

How can I delete the old chart files? could this be the problem?

Hi mtspp,

This is strange but it could be. You should go to project\options\packages and remove old TeeChart packages (*Tee100*.*) and enable v7 packages (*Tee107*.*). You should also check that at project\options\directories/conditionals\Search Path, v7 "Lib" and "Bin" folders are on top of the list. After that enable the left-bottom "Default" checkbox.

I cleared all files, set the path but it isn´t working... do I have to recompile? But everything is working when I add a new chart so it should not be a problem of a wrong compiled version!?!?

I have installed Report Builder Verison 10 with TeeChart support, could the problem be somewhere there?

I think I found the real problem now. When I uninstall the ReportBuilder TChart is working as it should. So it must be a problem with the ReportBuilder, maybe ReportBuilder is compiling the Report TChart support with the wrong version.

So I will try to contact ReportBuilder support again, maybe they have a solution for this problem

Hi mtspp,

Yes please, try contacting Digital Metaphors support because they are the ones who implement the Report Builder wrapper for TeeChart.

Hi Narcis,

I have to contact you again, because I still don´t hava a solution for this problem. After sending a lot of mails to the RBuilder support they also don´t know anything abaout this problem.

I completely reinstalled my system now with Windows XP, Delphi 2006 ( german ) and TChart 7.06 and everything is working fine. When I install RBuilder 10.01 the problem starts again.

I can start Delphi 2006 and the TChart components are still in the component list. When I open a old project with an TChart I get an error that the the needed files for the TChart components are not found.

I already recompiled TChart / RBuilder reinstalled Delphi 2006 and Windows XP

I don´t know what I could do to get this working.
