Clipboard SetText exception on VMWare client
posted

Hi,

We having a problem when trying to use the Clipboard in our Xaml application with enabled Clipboard copy functionality. The clipboard functionality works perfectly fine on any other hardware, however the failing ones are virtual PC's with installed VMWare application (provided by VMWare Horizon Client) limiting the clipboard access due policies. Here is a stack trace:

System.Runtime.InteropServices.COMException (0x800401D0): OpenClipboard Failed (Exception from HRESULT: 0x800401D0 (CLIPBRD_E_CANT_OPEN))

   at System.Runtime.InteropServices.Marshal.ThrowExceptionForHRInternal(Int32 errorCode, IntPtr errorInfo)

We have tried various combinations with clipboard sample application and we face same problem when we try to use Clipboard.SetText(). However, we found a workaround for this error to use Clipboard.SetDataObject(object) for text and this works without any exception. Is there any chance to enhance logic to cover for Xaml to handle this at Infragistics side?

However, based on our tests it looks like this approach is affecting paste and application is hanging. We enabled in various places copy functionality like this:

<igDP:XamDataGrid.FieldLayoutSettings>
<igDP:FieldLayoutSettings SelectionTypeCell="Range" AllowClipboardOperations="Copy" CopyFieldLabelsToClipboard="True" 
SelectionTypeRecord="Extended"
 ...../>
</igDP:XamDataGrid.FieldLayoutSettings>

Any suggestions on this topic?

best regards,

Tomas
