Failed to create 3dchart activex control

When calling Server.CreateObject("3DCHART.NChart.7"), it returns empty. The ActiveX control is registered in the registry. I have 3DChart.tlb, 3DChartM.ocx, and NChart.lic in my web server bin directory. I also have NevronConfig and NevronTemp directories that contain NConfig.cfg. Why Server.CreateObject failed? Please help.

Thanks in advance!

Actually, it didn't fail to create the chart object. It failed at NChart.ImportExport.SaveJPEGImage. Any one knows why?

Thanks,

Hi Cindy,

Most likely the issue is caused by the security permissions applied on the NevronTemp directory – generally you need to grant read / write list permissions to the IUSR and IIS_IUSRS accounts.


We strongly recommend using the .NET chart control (more information can be found at: http://www.nevron.com/Products.ChartFor.NET.Overview.aspx) as it is specifically designed to work with ASP.NET servers and has wider server and client side functionality.
