Using TChart in mulitple projects within a Program Group.

There was some confusion to my previous posting on the Forum.

My application has 15 DLLs and one executable as the main processing. Due to the size of the application it is necessary to use run time libraries. When I include the run time TChart into more than one DLL and/or EXE, I get errors. Mainly, the classes have already been created.

How do I include the run time TChart into more than one DLL/EXE within the same Project Group?

I am currently using TChartPro 7.08.

Test case available: Reference Test Case 3.

Hi RGSMike,

Have you posted the example project at our attachments newsgroup (news://www.steema.net/steema.public.attachments newsgroup)? Have you read my replies at the messages you posted there?

Sorry, I did not know the procedure for sending in the attachments. I will post the attachments.

You should note that I have reverified all the test cases and they still fail. I also have cleaned up the previous test case problems and have verified they will work in a stand alone directory. I don't like to waste anyone's time.

I also have included a readme.txt file in the test case on how to recreate the problem.

Hi RGSMike,

If you are a source code client, to solve this issue, you might try to modify the Teengine.pas unit initialization, adding an "if":

Code: Select all

if GetClass('TChartAxisTitle') = nil then
  RegisterClasses([
TChartAxisTitle,TChartAxis,TChartDepthAxis,TSeriesMarks ]);
