Chart FX 8 and unmanaged code.


Recommended Posts


We use Chart FX 6.2 in our projects. Now we want to upgrade to Chart FX 8, and i have downloaded the trial version to test it. We use Microsoft Visual C++ and access the chart FX 6.2 classes over the COM interfaces. I have used the regasm.exe utility of the .NET-Framework to export the type libraries from the Chart FX assemblies. But Chart FX 8 seems not to support COM interfaces any more - the exported interfaces are mainly empty. Then i tried out the MFC wrapper class for Windows Forms Controls (CWinFormsControl<>) to put the ChartFX8 Control into a Window. The program compiles and starts without errors, but when i move the mouse over the control it crashes with an NullReferenceException in the timer event handler. Are there any other ways to use the Chart FX 8 classes from unmanaged code?

Thanks in advance.
