Clipboard errors

[EP]

Hi, all. I posted my experience with clipboard problems in the Forum as follows: Hi, we have several troubles with a COM Add In using VSTO technics. What happens: The COM Add In does more then one clipboard operation in one thread (using the copy-paste-commands of the application). It works fine, except if: Virtual Box is running (on the host System where the Add In runs), with Windows Guest System and installed Virtual Box Extensions and with at least one user. Then we get clipboard errors, which show, that after a copy command the clipboard is empty or contains invalid data for the paste command. These errors don't occur, if there is no user on the guest machine or if there is a user, but the Virtual Box extensions are not installed. We feel there is a big bug in the Virtual Box extensions handling the clipboard. This error occurs only with Virtual Box (not with MS Virtual PC nor with VM Ware nor with TeamViewer Virtualization) and only with at least one user logged on to the guest and only with installed VB Extensions on the guest. The shared clipboard in the General Settings is turned off! I don't believe that the error occurs in our MS Office Solutions with VSTO COM Add Ins (I got the error in other add ins, too: clipboard empty or invalid data) because of the mentioned circumstances.

Please reopen if still relevant with a recent VirtualBox release.

I don't understand what here is obsolet. The error occurs and it is in the Virtual Box extensions. This I can and my arguments are still the same. With regards Eckehard
