Anyone here good with Visual Basic.NET ???

I am trying to make a program with a listbox of all 50 states.

Then when the user starts typing the beginning  letters of the state  into a textbox, the state will be highlighted in the listbox when enough letters have been typed.

Any Ideas???

Thanks,

Auto fill in is probably just a property of the textbox.

With a VB6 ListBox and ComboBox, all you have to do is set the Sorted property to True and it will allow you to select by type-matching.  Perhaps the .NET ListBox works the same?

EDIT: just realized you are typing in a TextBox, and not the ListBox.  Again, in VB6, I know exactly how to do this.  For example:

Private Sub txtStateName_KeyPress(KeyAscii As Integer)

   strBuffer = txtStateName.Text
   lngRetVal = SendMessage(lstStateList.hWnd, CB_FINDSTRING, -1, ByVal strBuffer)
   If lngRetVal <> CB_ERR Then
       lstStateList.ListIndex = lngRetVal
       KeyAscii = 0
   End If

End Sub

Basically, ListBoxes and ComboBoxes support a FindString function, but it is not exposed to VB.  The SendMessage is a Windows API call that does the same thing returning the index of the first item that matches.  The above code searches the lstStateList ListBox for whatever you've typed and selects the appropriate item if it matches.

The trick would be to see if the .NET ListBox supports a similar feature to search the list for a partial match.  Worst case would simply be to trap the TextBox change event and manually search the ListBox looking for a match.  Basically "For Loop" through the state ListBox and when you find one that partially matches the typed text, select that list index.  Although I've taken a VB.NET class and could figure it out, I don't have it installed at home to tinker with it.  I'm still a VB6 guy because I fear change

Good luck!

I won't get into the specifics, but the .NET ListBox supports a FindString method that will return the index of the first item that matches the typed string.  You can then set the SelectedIndex to that return value and it should select the appropriate state.  You can put code in the TextBox's TextChanged event to do the search.  The simple code looks like:

       Dim x As Integer = -1
       x = ListBox1.FindString(TextBox1.Text, x)
       If x <> -1 Then ListBox1.SelectedIndex = x
