Problem attempting to fill Datatable from a shared function 1

I have a DataTable in my local tables which I fill successfully from a button-click on a form. I now want the exact same process to fire from another form, so I took the Sub which fills the table and moved it to a shared functions module, which I use to store functions/subs I need to fire from multiple locations. Here's the code:
Code:
 Public Sub FillTree(ByVal FromPart As String)

        LocalInfoTables.TREEpartsTreed.Clear()

        Dim constr
        constr = My.Settings.M2MAydinOther

        Dim SQLstring As String
        SQLstring = "SELECT PartNo, ParentPart, qty AS PartQty, qtyExt AS PartQtyExt, identifier AS TreeID, TreeLevel FROM SerialPartTrees WHERE (ParentPart = '" & FromPart & "' AND LowerLevel = 'False') OR (TopPart = '" & FromPart & "' AND LowerLevel = 'True') ORDER BY TopPart, ParentPart, PartNo;"

        Dim con As System.Data.SqlClient.SqlConnection
        con = New System.Data.SqlClient.SqlConnection(constr)

        Dim da As System.Data.SqlClient.SqlDataAdapter
        da = New System.Data.SqlClient.SqlDataAdapter(SQLstring, con)

        da.Fill(LocalInfoTables.TREEpartsTreed)

        con.Close()
        con.Dispose()
    End Sub

When I have this code included in the code for the MngPartTree form, it fires fine. However, when I move this code to the ShardFunctions module, Visual Studio throws an error on the LocalInfoTables.TREEpartsTreed.Clear() and da.Fill(LocalInfoTables.TREEpartsTreed) lines, telling me that "Reference to a non-shared member requires an object reference."

Researching this error seems to indicate that I need to declare the datatable within this patch of code to get rid of this error; however, I'm trying to use an existing datable in the project which is viewed through a datarepeater on my form. Is there any way to overcome this, or will I have to include this code in two locations rather than one so that it can fire from the two different forms?

I've not got VS on this machine, so I can't check, but you could try something like:

[tt]
Public Sub FillTree(ByVal FromPart As String, [bold]ByVal dt As DataTable[/bold])

[tab]dt.Clear
[tab]......
[tab]......
[tab]da.Fill(dt)
[/tt]

I know I've used something similar in the past.


Hope this helps (or at least points you in the right direction).
 
Thank you, softhemc, it worked beautifully.
