Until now we worked with the evaluation version of TeeChart 7.07 for Delphi 5. We now have installed and (presumbly) registered Teechart Pro 8.02 (full version) on a new PC with XP SP2 and recompiled the code using the Pro version. The registration did not give any error message (it asked twice if it should use a direct internet connection or a proxy). There was no TeeChart (not even Delphi) installed on that machine before, so I rule out any 'leftover' files or registry entries that point to an old version.

The compile itself worked, but the resulting program seems to behave as though it only used the evaluation version. The test for this was using the 'Export' tab of the chart editor. We assumed it would now allow exporting the graphics data as .png, .jpg instead of being limited to .bmp and windows metafile in the evaluation version.

Is there a problem on our side, or do we have to do something else to allow export in .png/.jpg format? We also created a simple app with only a chart, a chart editor and a button and the behaviour is the same as above. Is there a way to test if the installed TeeChart considers itself registered or only in evaluation mode?

Hi we-mitarbeiter,

The easiest way you can check if your Delphi is using TeeChart's evaluation version is dropping a TChart in a form, right-click on it and select the "About..." option.

To check that all Pro version packages are installed you should go to Project->Options->Packages and check that no packages from the version shipped with Delphi are enabled and enable all TeeChart Pro v8 VCL packages listed. Then go to Project->Options->Directories/Conditionals and make sure that v8's "Bin" and "Lib" folders are on *top* of the Search Path list. Finally enable the left-bottom "Default" checkbox.

Hope this helps!

Thanks for your quick help.

It seems that Delphi is using the correct packages. The about box does not indicate a trial version. There are no Borland Chart packages listed (TeeChard removed them when it installed) and the list of search paths in the position you indicated is empty.

But our main problem remains. If I use "Edit Chart" in Delphi on the Chart object, I get an export dialog with lots of options for file formats. This was already the case with the evaluation version. But the compiled program still allows only a limited number of file formats. I understood this to change with the registered version:

Export as picture to JPEG, GIF, PNG, BMP, PCX, SVG, PDF, EPS, VML and WMF/EMF formats.

If anyone can bring light into this matter, I'd be very obliged to him.

Hi Ingo,

Ok, this is because you need to include necessary units in your projects uses section as described here.
