Steema Central

Hi,
I use code like this to copy a tChart onto the clipboard as a metafile:

Steema.TeeChart.Export.MetafileFormat METAGpic;
METAGpic = tChart1.Export.Image.Metafile;
METAGpic.EMFFormat = System.Drawing.Imaging.EmfType.EmfOnly;
METAGpic.CopyToClipboard();

When I try Ctrl-V onto a World document nothing is there.
It works for the other picture formats without a problem.

Why would the metafile not work? Is there a workaround?

Thanks,
fano

Hi fano,

Thanks for reporting. I've been able to reproduce the problem here and added it (TF02011312) to our defect list to be fixed for future releases. There's no workaround I can think of for now.

Hi fano,

After further investigation we found that metafiles cannot be copied to clipboard without going unmanged. As TeeChart.dll is 100% managed code, metafiles cannot and will not be copied to clipboard.

For further information please read:

I found this info and thought I hand it on. There is a suggested workaround in that article:

PRB: Metafiles on Clipboard Are Not Visible to All Applications

CAUSE
This problem occurs because the .NET Framework uses a new Clipboard format when it adds metafiles to the Clipboard. Other applications, such as Microsoft Word, or the operating system are not aware of this new format and, therefore, cannot paste or display the image.

Hi fano,

Thanks for the information. We are aware of such workarounds, but, as I commented before, this is not feasible with TeeChart as it is fully written in managed code and this workaround would require going unmanaged.
