About Get Data from Clipboard
-
I know that I have Data in the clipboard with the DataFormat.MetafilePict. But I can't get it. My code is more or less the next: ///////////////////////////////////////////////////////////// IDataObject iData = Clipboard.GetDataObject(); if ( iData.GetDataPresent( DataFormats.MetafilePict) ) { System.Object obj; System.Drawing.Imaging.Metafile pMetafile; obj = Clipboard.GetDataObject()>GetData(System.Windows.Forms.DataFormats.MetafilePict ); } ///////////////////////////////////////////////////////// Obviusly in the Debug, I enter inside the first if condition, so the code executes but the System::Object obj can't keep the data of clipboard and keeps a undefined value after the asignation. It seems a contradiction, isn't it ? :confused: Can anybody say me anything about get MetafilePict Data from Clipboard ? Advanced Thanks, everybody.;)
