Steema Central

I have just upgraded my TeeChart from 2010.01 to 2011.03 into C++Builder 2007 and I get a C++ Error that wasn't occurring before:

Teeprocs.hpp(717): E2113 Virtual function '__fastcall TCustomTeePanelExtended::GetDeviceContext(HWND__ *&)' conflicts with base class 'TWinControl'

Has anyone else seen this error and have a workaround/fix? I couldn't find anything on this in this forum.

Thansk in antincipation.

Hi Andrew,

Does this occur in a specific project or with all TeeChart related projects? Have you checked that your C++ Builder Include and Library search paths point to new TeeChart version "Include" and "Lib" folders?

Thanks in advance.

Thanks for the quick response. My TEEINCPATH and TEELIBPATH environment variables are set correctly (to ..\TeeChart 2011 for Delphi 2007\..).

It appears the problem occurs because I am also using Developer Express controls (version 2011.1.6) and - in particular - DevEx's Printing System library, which supports TeeChart.

Currently, my source fails to compile because DevEx's <dxPSTCLnk.hpp> file is included BEFORE Steema' <Chart.hpp>.

If I force the inclusion of <Chart.hpp> ahead of <dxPSTCLnk.hpp> then it compiles ok.

Perhaps this is something to do with overriding STRICT (which i have set to true)? That would change the function's signature, owing to HWND being different with/without STRICT.

Were you aware of this incompatibility with DevEx? (I will ask the same question on their website.)

Hi Andrew,

Thanks for your feedback.

No, I wasn't aware of that but it's Developer Express who does the TeeChart integration with their components. Actually a similar issue was discussed in his thread at DevExpress' forums, it might be helpful for you as well.
