    Strange VB.Net Drag and Drop Problem

    I am having a strange problem with my application the drag and drop works for fine for draging objects from one listview control to the other, but If I drag a file from the desktop it doesn't work in the listview control the DragDrop and the DragEnter Events won't even trigger.

    All I get is a drop Not Allowed cursor.

    I do have AllowDrop set to True.

    I have used the same code for a sample app, to test if the drag and drop will work there and it works fine there, it just won't for my app.

    Do you have any Ideals

    Thanks,
    QWERT

    Version 2010


    Private Sub lvwRemoteDir_DragEnter(sender As Object, e As System.Windows.Forms.DragEventArgs) Handles lvwRemoteDir.DragEnter

    If (e.Data.GetDataPresent(DataFormats.FileDrop)) Then
    e.Effect = DragDropEffects.Copy
    End If


    End Sub


    Private Sub lvwRemoteDir_DragOver(sender As Object, e As System.Windows.Forms.DragEventArgs) Handles lvwRemoteDir.DragOver

    Try
    Dim obj() As String = e.Data.GetData(DataFormats.FileDrop)




    Catch ex As Exception
    ' MessageBox.Show("Error Doing Drag/Drop")
    End Try

    End Sub

    No Drop Cursor on Drag and Drop

    QWERT,

    Did you solve this problem? I have exactly the same thing on a simple drag and drop, but yet have other VB.Net programs running the same VS 2010 on the same PC that works fine. I have Googled "No Drop Cursor" and "No Entry Cursor", but your post is the only one I have found that has experienced the same issue. If you have solved it I would appreciate you sharing the solution.

    Thanks
