Phonebook style search

Hi Everyone,

Currently I have a ListView filled with people's names. I also have a text box on the form. What I would like to do is this. I would like to create a phone book type search where the more letters that are typed into a text box for a persons name the more refined the search becomes. For example, if a person types an 'E' into the text box. The listView displays all people with an 'E' in the first character in there name. If someone types 'Er' into the textbox the search is refined to all people with 'Er' as the first two characters in there name, etc., etc. I currently have the ListView ordered by peoples names. Does anyone know how to accomplish this? I would appreciate any help. Thanks.

If all the data is in an array, then on each keypress, loop through the array for names beginning with the text in the box, clear the list and display the matches.

I have found this bit of information from the MSDN Help, but I cannot figure out how to get it to work right. It works fine if I use the information from the first column in the ListView, however, the people's names are located in the second column of the ListView. This is the column I want to search from. Any ideas on how to fix this? I would appreicate any help. Thanks. Here is the code.

Code:

---


Private Sub Command1_Click()
    Dim objItem As ListItem
   
    Set objItem = lvwMemberInfo.FindItem(Text1.Text, , , lvwPartial)

If objItem Is Nothing Then
    MsgBox "No match found."
    Exit Sub
Else
    objItem.EnsureVisible
    objItem.Selected = True
    lvwMemberInfo.SetFocus
End If

End Sub

Private Sub lvwmemberInfo_LostFocus()
    Dim i As Integer
    For i = 1 To lvwMemberInfo.ListItems.Count
        lvwMemberInfo.ListItems.Item(i).Selected = False
    Next i
End Sub

Here you go, see if this will work for you.

VB Code:

Private Sub Form_Load()
    ListView1.ListItems.Add , , "Brunhauser, Mary"
    ListView1.ListItems.Add , , "Brown, Jack"
    ListView1.ListItems.Add , , "Clark, Kenton"
    ListView1.ListItems.Add , , "Cloude, Fred"
    ListView1.ListItems.Add , , "Fredrickson, Francine"
    ListView1.ListItems.Add , , "Woodard, Curt"
    ListView1.ListItems.Add , , "Jankowski, Robert"
    ListView1.ListItems.Add , , "Frinkle, Jennifer"
    ListView1.ListItems.Add , , "Hauser, Scot"
    ListView1.ListItems.Add , , "Alberra, Elmore"
    Text1.Text = ""
End Sub
 
Private Sub Text1_Change()
    Text1.Text = StrConv(Text1.Text, vbProperCase)
    Text1.SelStart = Len(Text1.Text)
    For x = 1 To ListView1.ListItems.Count
        If Left(ListView1.ListItems(x).Text, Len(Text1.Text)) = Text1.Text Then
            ListView1.ListItems(x).EnsureVisible
            ListView1.ListItems(x).Selected = True
            Exit For
        End If
    Next x
End Sub

You can kill the stuff in the Form_Load() Event, I just put it there for testing.

Change Text1_Change to this:

VB Code:

Private Sub Text1_Change()
    Text1.Text = StrConv(Text1.Text, vbProperCase)
    Text1.SelStart = Len(Text1.Text)
    [b][i]If Text1.Text = "" Then
        ListView1.ListItems(ListView1.SelectedItem.Index).Selected = False
        Exit Sub
    End If[/i][/b]
    For x = 1 To ListView1.ListItems.Count
        If Left(ListView1.ListItems(x).Text, Len(Text1.Text)) = Text1.Text Then
            ListView1.ListItems(x).EnsureVisible
            ListView1.ListItems(x).Selected = True
            Exit For
        End If
    Next x
End Sub

This way, if Text1.Text is empty, nothing is selected.

Thanks ExcalibursZone. That code you sent works very well. One other question though. Once an item has been found, I want to be able to press enter on the keyboard and have another form open with more information about that person. The text box still has focus but the ListView has the correct record highlighted. Is there anyway to do this without removing the focus from the text box?

Very Simply:

VB Code:

Private Sub Text1_KeyDown(KeyCode As Integer, Shift As Integer)
    If KeyCode = 13 Then
        Form2.Label1.Caption = ListView1.SelectedItem.Text
        Form2.Show
    End If
End Sub

Or whatever you wish to show based on the text in the listview.

I keep getting an error that says: Operation is not allowed on an object referencing a closed or invalid connection. Then when I debug I shows me the connection string on the second form. Any ideas?

What connection string? This should go in form1 and a label (for this example) and only a label should be on form2.
