Passing control back to Parent form

Hi,

I currently have a main form, with a treeview and a listview on it, when data is loaded into the listview I have a progressform displayed which displays the current progress of the listview populate method. There is also a Stop button on the progress form which the user can click to abort the population of the listview.

The way I have it running at the momment is

[code]
Dim oProgress As New frmLoadProgress()
oProgress._MaxValue = Datasource.Table.Row.Count - 1
oProgress.Show()

Dim oRow As Data.DataRow
For Each oRow In Datasource.Table.Rows
 
    '// code to populate Listview
   
    oProgress._IncValue(1) 'Increase progress bar value by 1
    If Not oProgress._LoadStatus Then 'If value = false then uses clicked stop button
        Exit For
    End If

Next
[/code]

In theroy I would loop through each row in the DataSet adding it to the listview, after each row I could increase the progress bar on the oProgress form by 1.  I'll Also check a boolean Value to see if the user clicked Stop before loading the next row.

The problem is when I use the oProgress.Show() method to display the progress form control is passed to oProgress and the program stop untill oProgress is closed.  Would I need to create a new thread have the other form loaded in another thread? So both forms run simutainously?
