Hi guys:

I have a ComboBox control and the style property is set to 2, so the user cannot write on it, this combo has all the States of and I filled up like this:

Do while not rsStates.Eof
     cbmStates.AddItem rsStates!StateName & space(50) & rsStates!StateId
     rsStates.MoveNext
Loop

So, in the combo has "California                                     CA"  and one of this for each state.

but I need to display the data from a table, at this point I cannot put any data on the combo because style 2 is read only.

If my table has Born in Texas, I need to put "Texas" on the combo.

I guess, I need to use the listindex property but how to assing it.

Thank you guys.

This is a routine that I use

Add the below routine to your module or class

on your form load or where ever you populate your combo box do this.

Combox_Listindex_Selector cbmStates, rsStates!StateName



Public Sub Combox_Listindex_Selector(ctrl As ComboBox, str As String, Optional no_right_trim As Boolean = False)
    Dim i As Long
   
    ctrl.ListIndex = -1
   
    If Trim(str) <> "" Then
        For i = 0 To ctrl.ListCount
       
            If no_right_trim Then
                If UCase(ctrl.List(i)) = UCase(Trim(str)) Then
                    ctrl.ListIndex = i
                    Exit For
                End If
            Else
                If UCase(Trim(Right(ctrl.List(i), 10))) = UCase(Trim(str)) Then
                    ctrl.ListIndex = i
                    Exit For
                End If
            End If
        Next i
    End If



End Sub

I do the same thing as you do which is to load the name and hide the code deep in the string. the routine that I gave you will ignore the hidden code so that is why I have the no_right_trim parameter. This routine will work with any combo box with style set to 2.

Thank you Lunch,

I put this code on the General - Declaration Section of my form:

Combox_ListIndex_Selector cmbStates, rsCatEstadosUsa!Estado

But when I try to run it,  appears an compile error: "Invalid outside procedure"  in the cmbStates.

>>General - Declaration Section of my form

No, put it in module or class. If you want it on your form then put it on the bottom. I think you have it on the very top where you declare global variables.

should look something like this.


Option Explicit


Private Sub Form_Load()

end sub

Public Sub Combox_Listindex_Selector(ctrl As ComboBox, str As String, Optional no_right_trim As Boolean = False)
    Dim i As Long
   
    ctrl.ListIndex = -1
   
    If Trim(str) <> "" Then
        For i = 0 To ctrl.ListCount
       
            If no_right_trim Then
                If UCase(ctrl.List(i)) = UCase(Trim(str)) Then
                    ctrl.ListIndex = i
                    Exit For
                End If
            Else
                If UCase(Trim(Right(ctrl.List(i), 10))) = UCase(Trim(str)) Then
                    ctrl.ListIndex = i
                    Exit For
                End If
            End If
        Next i
    End If



End Sub

OK, Let me find out where you are but first are you new to VB? Just now learning VB6? I do not want to give you instructions only to insult you if you much more advance.

oh no, I allready made some apps. I like to use listboxes because the user doesn't have to use the mouse, but I think I'm going to put the following and it solves the question:

On keyPress Event

Keycode = 0

end sub.

Thank you lunch.
