Importing ActiveX (.tee) files

[matteo]

I'm switching from the ActiveX version to the .NET version of teechart,
I have a lot of templates saved in the old binary format (.tee)

using

TChart.Import.Template.Load(filename)

I'm occurring in an exception saying the file is not correct.

Is the .NET template format different?
And it is possible to convert the old .tee files to the new native format ?

Thanks,
Matteo

Hi Matteo,

I'm sorry but .tee files are not compatible with TeeChart for .NET, which uses .ten files.

Quina llastima!!!

But in every case I'm trying to use the new native format and having problem too. (using the version 2.0.2511.18118)

I tried several things:
-To export a template from the designer: when I click the button file size on the save dialog, the dialog close, and if save a chart , the resulting file is 17 bytes large.

- If I try to call export function at runtime I have the exception reported below. I see that a similar errror was experienced also by another user,
but maybe I'm missing somethig basic... I will try to post the sample application that get this error.

Thanks,
Matteo Tesser

Yes, it's a pity .

Yes, this a problem some of our users reported recently:

It seems to be quite an inconsistent issue. Anyway, we will try to find a solution ASAP.
