Dear Steema,

we're using TeeChart6 for our projects in Visual Studio.
Some months ago I changed the development environment from Visual Studio .Net to Visual Studio 2005 and I compiled the project new.
Now we have problems in our charts while moving the cursor. We're using the fast line series to display our measurement curves. The option SetSnap ist set to 1, so the cursor can be moved only to the position of a measuring point.
Sometimes it happens that the cursor gets stuck, so it can’t be moved anymore. And sometimes the cursor jumps to the first measuring point.

These problems we never had with Visual Studio .Net and TeeChart6.

Is it a problem you know?

Does an upgrade to TeeChart8 solve this problem?

When we decide to upgrade, does it mean a lot of changes in the source code?

I hope that you can give me an advice to solve the problem.

Regards,
Anne

Hi Anne,

These problems we never had with Visual Studio .Net and TeeChart6.

When you say Visual Studio .NET do you mean Visual Studio .NET 2003?

Is it a problem you know?

No, AFAIK this is not a known issue.

Does an upgrade to TeeChart8 solve this problem?

Could you please send us a simple example project we can run "as-is" to reproduce the problem here? We will try the project using v8 as well.

You can either post your files at news://www.steema.net/steema.public.attachments newsgroup or at our upload page.

When we decide to upgrade, does it mean a lot of changes in the source code?

No, backwards compatibility is something we specially care about when developing new versions. Moreover, v8 includes a tool set for automatically converting older versions projects.

Hi Narcís,

thanks for the fast reply.
Before I was using Visual Studio .NET 2003.

At the moment I can't convert our big project into a small one. It will take me too much time.

How can I go on solving the problem?
Do you recommend to make the upgrade?

Greetings, Anne

Hi Anne,

I've done some tests and I couldn't reproduce your problem here. I've made two tests, one with vb and one with c# under Visual Studio 2003 .NET.

Both of them consisted in create a new project, add a new Chart (v6.0.1.1), add a fast line series and add a cursor tool (and fill some values to the series, associate the series to the cursor tool and mark snap points for the cursor tool). They work as expected. I save them and open in Visual Studio 2005. They are updated without errors and they still work as expected in the new IDE.

So, could you try to do a simple example project to reproduce the problem here? Or could you tell us the steps I miss to reproduce it?
