Error terminating application.

[ssjun]

Hello,

We have a VC++ MFC application and we are using TeeChart ActiveX control 2018(20180209 Release).
The following error occurs during the upgrade from "Teechart8" to "Teechart2018".
This error does not occur in "teechart8".

OS : Windows 7 or Greater
Development Environment : VS 2013 Update 4

<Crash Scenario>
========================================================================================================
In the OnCreate() function

m_TeeChart.Create(NULL, "", WS_CHILD | WS_VISIBLE | WS_CLIPSIBLINGS, CRect(0,0,0,0), this, IDC_TCHART, NULL));
m_TeeChart.SetVisible(true);


After that, I start the application with m_TeeChart.SetVisible (FASLE) as hidden, and when it closed, the following Crashes occurs.
If even a single window containing chart is open, crash is not observed.

Hello,

Can you please arrange a simple example project we can run as-is to reproduce the problem here?

Thanks in advance.

Hi Yeray,
Thanks for reply!

We can remotely connect the PC that crashed at the end.
Developing a sample project takes a lot of time.
We request remote support and remote support via Teamview.

please let us know suitable date/time for remote session.
Thanks for the understanding!

Hello,

Have you tried to do this to see if it works also for you?

If a condition for the error to appear is to have no charts loaded (after showing a chart), a workaround could consist on having a dummy chart always loaded, hidden behind a panel for example.

Hi Yeray,
Thanks for reply!

I do not understand what you proposed.
If you have sample code to help you understand, please attach it.

And please answer whether remote support is not possible.

I'm not a VC++ expert but I'm trying to prepare a simple example project with a dummy chart hidden by a panel.

And please answer whether remote support is not possible.

We'll do it if necessary (note this is an option for Pro Support customers).
However, connecting to a machine and seeing an application to crash won't help us to debug the problem.
A simple example project would do it, which sends me to a couple of posts above:

Developing a sample project takes a lot of time.

Why? It doesn't mean to simplify a big project, but starting a new one with the minimum code to reproduce a problem.

Hello,

I'm not a VC++ expert but I'm trying to prepare a simple example project with a dummy chart hidden by a panel.

Here it is the project, made with VC++ 6:

Note this is just to understand the concept of having a permanent hidden chart in the main dialog and another chart in another dialog opened & closed on demand.
