TeeChart 8 hanging under Windows 2008 R2 Terminal Server

[insoftware]

Hi,

We are using TeeChart ActiveX in our Visual C++ application for years but recently our customers starter reporting a weird issue: when our application is run in Terminal Server session on Windows 2008 Server R2 and customer tries to open a dialog with embedded TeeChart, whole application hangs.

Issue was first reported with TeeChart 5. Recently, we have updated TeeChart to version 8 (8.00.0.8 exactly) and the problem still appears.

After our investigation we have found that hanging happens during TeeChart control initialization. It seems that TeeChart tries to enumerate available printers and it hangs during enumeration. Here is appropriate stack walk information:

Please note that TeeChart8.ocx has loaded at different address:

Code: Select all

 TEECHART8.OCX C:\Windows\System32\TEECHART8.OCX N/A N/A Binary was not built with debug information.  71 8.00.0.8 6/19/1992 11:22 PM 04270000-048C8000* Waa.DMP: Native 

We have also found that:
- printing from Windows application works properly at the time when TeeChart hangs (tested with our application and Notepad)
- disabling local printer redirection when connecting to Terminal Server solves the problem (i.e. TeeChart no longer hangs during initialisation), however this solution is not acceptable for our customers - they need printing using local printers.

Can you please solve the problem with TeeChart?

Hello insoftware,

I inform that you can find in costumer page a new release of TeeChartActivex in English where the problem of hang is solved. Please download it and check if now your TeeChartActivex is installed as expected.

Thanks,
