It worked, thanks!

I sent you my program with a description how to reproduce the issue.
Could you see it?

Look it this example of reproducing a bug in CursorTool when FastCursor = true: Move the cursor in our previous program example so the cursor with cross hair is drawn. Press ALT+TAB to show a different program in Windows. While this different program is overlapping the TeeChart program move the mous...

Generally speaking your .net version of TeeChart is MUCH slower than the VCL version 2010 we used with Delphi some years ago.
At that time we even worked with up to 2.000.000 point in each series, and the cursor tool still worked acceptable.
Can you recognize this picture?

Yes, I should have mentioned that.
The problem with using FastCursor is that it is flickering, and sometimes redrawing of the chart is not working correctly (e.g. lines left on chart).

Hi, We experience the Cursor Tool to be very slow drawing. To track down the problem we ended up isolating it with the following code. Note that only one series is added. When more points are added to this series the CursorTool is responding slower and slower. When setting DrawAllPoints to false the...

But how could our program work until now??

It is at design time in Visual Studio, when we try to compile or save the project.
The property CalcYPosValue is some TeeChart internal stuff.

Hello,

all of a sudden when we try save changes to our project we get the enclosed error message.
This means that we can't save the project, and therefore can't do any changes to our project.

Please inform what to do ASAP, as our programmer is waiting!

Hi Narcís, The TeeChart.dll you sent me is working, so we are up and running again, thanks god!! What is going to happen now? I expect that the license issue will be corrected somehow, so we can use the official version of the TeeChart.dll in future, and thereby not getting trouble with updates etc.?

Please tell us what we can do to speed things up.
Do we need to buy a pro-support license??

Some more information:
previous builds of the program also generated a TeeChart.xml file in the destination folder besides the TeeChart.dll file.
How can that be, and is that TeeChart.xml file necessary?

Same situation with the two files you sent. We have tried it on two different PCs. The errors in the log were as follows: Faulting application name: ChartLicenseTest.exe, version: 1.0.0.0, time stamp: 0x5225b2d5 Faulting module name: KERNELBASE.dll, version: 6.1.7601.18015, time stamp: 0x50b83b16 Ex...

Did you receive our email with the project failing on our PCs?
Knowing we don't subscribe to the pro-support, we still bought the license, and so far a product that is not working.

OK, you've got mail!
