I have a WPF application. I want to allow users to drag and drop "files" (or their visual representation) from my WPF windows to the real Windows explorer.
This I managed to do by using the native DoDragDrop from Ole32.dll
[DllImport("ole32.dll", CharSet = CharSet.Auto, ExactSpelling = true, PreserveSig = false)]
public static extern void DoDragDrop(System.Runtime.InteropServices.ComTypes.IDataObject dataObject IDropSource dropSource, int allowedEffects, int[] finalEffect);
This works great.
But rather then copy the file, I want to just get the destination. i.e. if the user dragged the file to an explorer opened on C:\Folder - I want to get C:\Folder... Or at least get the object on which the drop event occurred at (which is outside my application), and hopefully I could then get the path from that object.
Unless you created both the target and destination applications, you cannot get the information about the destination or target application.. This information is abstracted by design and is limited
Caveat : unless you write some sort of hook or Dll injection method to hook on the drag on drop events and monitor for them
