hi, is there a working vb.net way to resize last column of listview to fill remainder of listview that anyone knows of?
i've tried
http://www.devx.com/vb2themax/Tip/18746
Private Sub ListView1_Resize(ByVal sender As Object, _
    ByVal e As System.EventArgs) Handles ListView1.Resize
    ListView1.BeginUpdate()
    ListViewHeader2.Width = ListView1.Width - ListViewHeader2.Width - 27
    ListView1.EndUpdate()
End Sub

the problem comes that when there are more items  in the listview than those that are visible,
then because vertical scrollbar is added, a horizontal scrollbar is added as well, thus the value of 27 doesnt work

the autoresize trick (www.codeproject.com/cs/miscctrl/AutoResize.asp)
wont work either because it's in C and it uses send keys


this is prob the best i've seen but its in c# , could anyone possible help me do this in vb?

The Solution
To implement the the auto-size of the last column, subclass the ListView control, and override the WndProc method.

protected override void WndProc( ref Message message )
{
    const int WM_PAINT = 0xf ;

    // if the control is in details view mode and columns
    // have been added, then intercept the WM_PAINT message
    // and reset the last column width to fill the list view
    switch ( message.Msg )
    {
    case WM_PAINT:
        if ( this.View == View.Details && this.Columns.Count > 0 )
            this.Columns[this.Columns.Count - 1].Width = -2 ;
        break ;
    }

    // pass messages on to the base control for processing
    base.WndProc( ref message ) ;
}


thanks!

Hi JXharding,

Public Class mylistview
    Inherits ListView

    Protected Overrides Sub WndProc(ByRef m As System.Windows.Forms.Message)
        Const WM_PAINT As Integer = 15
        Select Case m.Msg
            Case wm_paint
                If Me.View = View.Details Then
                    Me.Columns(Me.Columns.Count - 1).Width = -2
                    Exit Sub
                End If
        End Select
        MyBase.WndProc(m)
    End Sub
End Class

sorry forgot something (I never got the hang of thinking and typing at the same time)

Public Class mylistview
    Inherits ListView

    Protected Overrides Sub WndProc(ByRef m As System.Windows.Forms.Message)
        Const WM_PAINT As Integer = &HF
        Select Case m.Msg
            Case WM_PAINT
                If Me.View = View.Details And Me.Columns.Count > 0 Then
                    Me.Columns(Me.Columns.Count - 1).Width = -2
                    Exit Sub
                End If
        End Select
        MyBase.WndProc(m)
    End Sub
