TeeChart .NET Licensing model and plugin architecture

[jhirsch]

Hello,

I have a plugin based application where certain plugins (that are loaded at runtime) use TeeChart, but the main .exe does not. With the current TeeChart licensing (System.Component.LicenseProvider) I cannot instantiate a plugin that uses TeeChart unless the main .exe project has a license file as well as a Reference to the TeeChart dll. I would like to remove the TeeChart reference from the main .exe since it is only needed by the plugin.

I saw another post in this forum (which I can't find again) where another user had the same problem.

Could you please let me know of a possible solution or workaround??

Thanks...
JHirsch

Hello,

For this application configuration format you need to use the plugin version of TeeChart. That allows dynamic loading of modules (dll assemblies) that use TeeChart, at runtime without need for licenses.licx in the loading application.

Please send an email to sales@steema.com, including your customer id, requesting the plugin version of TeeChart and they will send you the information necessary to access it.

Hello,

Thanks for the response. I received the plugin version of TeeChart, but it appears as though the installer may have included the licensed version by mistake. When using the TeeChart.dll found in the unlicensed installer, I find the same licensing requirements as with the licensed version.

I also received a "PluginTestSteema" project / sln that demonstrates the plugin use. When I use the TeeChart.dll included in the "PluginTestSteema" demo, it works fine without the licensing requirements.

The TeeChart.dll version included in the unlicensed installer is:
3.5.3416.24805

The TeeChart.dll version included in the "PluginTestSteema" project is:
3.2.2796.22187

I don't know what the differences are between versions... but for the moment I suppose I'll use the dll found in the demo project...

Thanks,
JHirsch

Hi JHirsch,

I'll send you an e-mail with the URL to download the plugin license. This installer is updated with every new TeeChart for .NET v3 maintenance release.
