TeeChart in .net Class in Web App problem licence problem

Hi

I have a .net class which uses the TChart class to generate charts directly into a image files stored on the harddisk. I have added the following licenses.licx file as an embedded resource in this dll.

Steema.TeeChart.Web.WebChart, TeeChart, Version=3.5.3188.18562, Culture=neutral, PublicKeyToken=9c8126276c77bdb7
Steema.TeeChart.TChart, TeeChart, Version=3.5.3188.18562, Culture=neutral, PublicKeyToken=9c8126276c77bdb7
Steema.TeeChart.Chart, TeeChart, Version=3.5.3188.18562, Culture=neutral, PublicKeyToken=9c8126276c77bdb7

This DLL is then used by an ASP.NET website, but I keep getting the following error message :

"An instance of type 'Steema.TeeChart.TChart' was being created, and a valid license could not be granted for the type 'Steema.TeeChart.TChart'. Please, contact the manufacturer of the component for more information., "

Teechart WebChart is also used in other places on the ASP.NET website, which is working fine, and I also have the same licenses.licx in the website's bin directory.

Do you have any ideas what the licenses problem with my dll is?

Many Thanks

Hi Again

A bit more information.

I have create a test console application to test my DLL. When I run the console app without the licenses.licx embedded into the console project I get the same error message, but as soon as I embedded the licence file into the console app as well. (as per tutorial 17's instruction) it then works.

So it looks like I need to embedded the licence file into ASP.NET some how?

How can I do this??

Thanks.

Hi KeynetixLtd,

Yes, as told in tutorial 17, licenses.licx needs to be compiled as an embedded resource in the ASP.NET applications. Are you doing so?

Thanks in advance.

Hi KeynetixLtd,

You could check the ASP.NET demo project shipped with TeeChart. You'll find it at C:\Program Files\Steema Software\TeeChart for .NET v3\TeeChartForNET. There you'll see how licenses.licx is included in the project and selecting it and going to its properties window you'll see what I mean.

Thanks in advance.
