Microstation Connect - C# - Addin: Drag&Drop from other applications like WindowsExplorer

Hello all,

how can we implement drag and drop for dgn files. We have another application that can be used to drag a dgn file from there to Microstation. After Dropping the file into Microstation, Microstation should open it. This should be done the same way you can do it with Windows Explorer. In the SDK API documentation we found several classes like DragDrop or the IDialogManagerControlDragDrop interface. Unfortunately, without an example, the implementation does not succeed.

Thanks in advance!
