ListView.SelectedItems.Clearcalled ProgramInformationFrm. I call this from from 2 other forms. One is ProgramSearch Frm, the other is OpenNCFrm. The search form accepts criteria from a user ans searches a sql table for any nc program that matches the criteria. The open form gives the user a list of programs that have not been added to table yet. Ok, enough background. What is happening is if I use the search from and get 8 results the first item is selected per my code. Now I close that form get into the add form, add a new record. It writes to the table, clears the listview on the info table, and then shows the infofrom. The item is not selected, but is the only item in the list. It should be selected. Also in debug I still have the previous value from the first time the form was shown. Here's my code OpenNCFrm.Visible = False ProgramInformationFrm.ProgramsLV.SelectedItems.Clear() ProgramInformationFrm.ProgramsLV.Items.Clear() Dim item As New ListViewItem(tmpNCFile) ProgramInformationFrm.ProgramsLV.Items.Add(item) ProgramInformationFrm.ProgramsLV.Focus() ProgramInformationFrm.ProgramsLV.Items(0).Selected = True ProgramInformationFrm.ShowDialog() On Mon, 13 Mar 2006 06:59:27 -0800, Mike

(Note: In VB6, changing a TabIndex in a control reindexed the other controls that had a TabIndex. I don't know about earlier versions, but in VB2005, changing a TabIndex of a control does not reindex the others, so you can wind up with more than one control with the same index value and unpredicitable results.) 2) Run the .exe in bin\debug a couple of time and see if you are getting the expected value results. Gene Ok got it working. To pass the value I am doing this;
ProgramInformationFrm.ProgramsLV.SelectedItems.Clear() ProgramInformationFrm.ProgramsLV.Items.Clear() Dim item As New ListViewItem(tmpNCFile) ProgramInformationFrm.ProgramsLV.Items.Add(item) ProgramInformationFrm.ProgramsLV.Items(0).Selected = True ProgramInformationFrm.ProgramsLV.Select() ProgramInformationFrm.ProgramsLV.Items(0).Focused = True ProgramInformationFrm.ShowDialog() On form load of ProgramInformationFrm I know use tmpNCFile = Me.ProgramsLV.Items(0).Text instead of Me.ProgramsLV.SelectedItems.Item(0).text to return value of the first item in the list.
