Hello banzatto,

I couldn't reproduce your problem here using last version 4 TeeChart.Net. Please, you could say which version of TeeChart are you using?
If you are using last version, please you could send us a simple project because we can reproduce the problem here?

Thanks,

I'm using version 4 of the TeeChart.NET. My problem is very simple, i had installed in vs2008 the version V2 of the TeeChart.Net, and now installed the version 4 of the Teechart.net in vs2008 running on Windows Vista 64 bits. In my computer the application running normally and Teechart Commander with editor button is function normally too, but in other computer no function. Follow the message of error:

System.NullReferenceException: Referência de objeto não definida para uma instância de um objeto.

I try change the commander bar by chartcontroller, but occurs the same error.

Hi banzatto,

Thanks for the information. In that case this may be a license installation issue. Please read the threads below about similar issues.

But installation is Ok. In my computer TeeChart running normally. The problem is only teechart editor in other computers.
I followed the steps, but problem persists.
I found other messages speaking of the problem with TeeChart and 64 bits, etc... but messages were old..

Hi banzatto,

Does this also occur when compiling TeeChart features demo at the development machine and deploying it?

Thanks in advance.

[banzatto]

No, only in other machines, in development machine running normally.
I compiled TeeChart demo and running in Windows XP 32 bits and in the basic features example button in "tchart1.showeditor()" happens problem but in Editor Options example not.

Hello banzatto,

After some testing here we think the problem you are experiencing is TF02014621 an issue which was reported a few weeks ago: http://www.teechart.net/support/viewtop ... 621#p44652. As you can see on the thread above, a workaround is provided there and also has been fixed for next TeeChart for .NET 2009 maintenance release which is imminent.

Can you please check if suggested workaround solves the problem at your end to confirm it's TF02014621 also?

Thanks,

Hi banzatto,

A new maintenance with a fix for TF02014621 has been posted.
