Situation:

need to show image while doing a .fill

I have tried hiding the datagrid and making the images visible. that didnt work at all.

I tried creating a thread to show image then fill the hide image.  That worked good.  However when I do that the datgrid has dual vertical scroll bars.

so itried to create the thread inside my sub, same result.
Application.doevents hasnt helped.



' Private Sub StartDoWork()
    '  Dim workThread = New Threading.Thread(AddressOf Me.showimage)     <  I have changed this several times
    '  showimage()
    '  workThread.Start()
    '  hideimage()

    ' End Sub

    Private Sub DoWork()

        threadactive = True  ' just for me to know the fill is progress

        Application.DoEvents()
        showimage()

        'Dim workThread = New Threading.Thread(AddressOf Me.showimage)
        'workThread.Start()

        Me.DbDataSet.Clear()

        Me.OleDbConnection1.ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;" & _
       "Data Source=" & DBNAME & ";Persist Security Info=False"

        'Application.DoEvents()
        Me.OleDbDataAdapter1.Fill(Me.DbDataSet)

        '// Do your work here

        hideimage()
        threadactive = False
    End Sub

    Public Sub showimage()                           <-- To show and hide images
        Me.DataGrid.Hide()
        search_lbl.Show()
        showbx.Show()
        showbx1.Show()
    End Sub
 Public Sub hideimage()
        Me.DataGrid.Show()
        search_lbl.Hide()
        showbx1.Hide()
        showbx.Hide()
    End Sub

This is another way I have tried it:

   Private Sub StartDoWork()
        Dim workThread = New Threading.Thread(AddressOf Me.DoWork)
        workThread.background = True
        workThread.Start()
    End Sub

    Private Sub DoWork()

        threadactive = True

        Application.DoEvents()

        showimage()

        'Dim workThread = New Threading.Thread(AddressOf Me.showimage)
        'workThread.Start()

        Me.DbDataSet.Clear()

        Me.OleDbConnection1.ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;" & _
       "Data Source=" & DBNAME & ";Persist Security Info=False"

        'Application.DoEvents()
        Me.OleDbDataAdapter1.Fill(Me.DbDataSet)

        '// Do your work here

        hideimage()
        threadactive = False
    End Sub

I'm assuming that the image is inside a picture box and is in the same location as the datagrid, is that correct? If so, then would it be ok if you make the picture opaque so that you can see through it and consequently see the datagrid? Or vice versa.

Try this:
