Application startup delay using Teechart

[dauser]

Hello,

I'm facing a strange delay during application startup when using TeeChart component.
Trying to investigate the problem, I made some trials with an "empty" application: just a winform with and without a TChart instance creation logging some system timestamps.
I found out a different behaviour, not only using TeeChart or not, but also if I'm logged into a domain or not:
- when not logged on a domain I have, at each startup, a same delay (variable depending on system); in this trial 20secs, in some cases also 1 minute;
- when logged into a domain I have at first startup a delay comparable to previous one, and a negligible delay for following startups.

Anyway, I cannot explain a delay of this type (20 secs-1 min) just for a simple command
this.tChart1 = new Steema.TeeChart.TChart();

Monitoring CPU and memory I cannot find any particular charge during this delay time; application seems just stuck or waiting for something.
Any ideas, anyone?

Hereafter the results in the different cases:

Hello Dauser,

We would be very grateful if you could do the same test, you have done, using the unsigned assemblies you find in the similar folder as next:
C:\Program Files\Steema Software\Steema TeeChart for .NET 2012 4.1.2012.09280\net40\x86\NoDigitalCertificate.
When you have made this test, could you tell us which results do you get?

Thanks,

Hello Sandra,

I made the same tests using the unsigned assemblies (Release 4.1.2012.05100 - target framework .NET 3.5) and, as far as I saw, delay time is now negligible in all cases.

So, have I to use these assemblies in my projects?

Thanks

Hello Dauser,

So, have I to use these assemblies in my projects?

Yes, the reason of your problem comes for the Digital Certificate as explain in next both threads:

http://www.teechart.net/support/viewtop ... gital+sign

I recommend you read all of posts of both threads to understand the problem and because you need unsigned assemblies to solve the issue. If you not understand something please let me know.

Thanks,
