Hey guys,
All of a sudden my NetAdvantage tab on my toolbox in VS2008 stopped working. Whenever I try to drag a control from the toolbox onto my page, I get the following error:
The operation could not be completed. Invalid FORMATETC structure.
I tried removing the tab and readding it and it didn't work. I also tried removing the references to Infragistics in my project and readding them and it also didn't work.
Any help on this would be much appreciated.
Thanks,
Ilija
I too was getting this on a project (minus the FORMATETC bit) was just saying "Operation could not be completed", no other details. Followed all the suggested solutions, none of which worked... then just by chance (after 4hrs of trying) I noticed that the "licenses.licx" file hand somehow became blank... re-added the Infragistics stuff in there and walla, it finally worked again!
