Private Sub btnCalc_Click()
    Dim blnOK As Boolean
   
    blnOK = checkErrors
   
    If blnOK Then
        calculatePrice
        lblPrice.Caption = FormatCurrency(totalPrice)
        lblCost.Caption = FormatCurrency(totalCost)
        lblHours.Caption = totalHours
        Set lstPart.Recordset = rsPart
       
        highlightUsed
        lstPart.Locked = True
       
        blnQuoteGiven = True
    End If
   
   
   
End Sub

Public Sub highlightUsed()
    'highlights the row in the listbox that has the price that was used for the estimate
   
    Dim i As Integer
    For i = 1 To lstPart.ListCount
        If lstPart.Column(1, i) = rsPart!WAREHOUSE Then
            lstPart.Selected(i) = True
            Exit Sub
        End If
    Next
End Sub

"You can't lock a control while it has unsaved changes"

I'm trying to highlight the row in the listbox which has a value that has a certain value in it and then lock it so that it cannot be unselected.

just to note, listbox entries start subscript start from zero

it should be for

for i = 0 to lstPart.ListCount-1


but not seen your error with regards to a listbox before

I believe, at least in Access, If you have column headers they count as the first row, but i will double check.

ok, I didnt realise u had column headers, in that case then yes, u start from 1

What is rsPart, is that rs anything to do with current form?
Have u tried creating a seperate rowsource, perhaps set rowsource using SQL instead

Hmmm, I wonder if its changes in the form that your in, hence the error message
Though it dont make sense why it complains about it when u try to lock a listbox
Thats MS Access for ya


try one of two things

Me.Requery

or

Me.Dirty = False

before u lock the listbox

doesn't work.  I also tried putting the recordset back to the listbox and used dbOpenSnapShot as the type. That didn't work either

I made a temporary fix.  I'm storing the index i want selected in a module level variable and using the listbox click event to reselect it everytime a different list item gets clicked on.

But i'm still open to a real fix

I thought about that also, but I thought u wouldnt like that idea as its a hack

what happens if u disable the listbox instead of locking it, does that make a difference?

Disabling it works, but poses a problem if i want to allow them to scroll still.  I guess Lock would do the same thing? so i'll just have to make sure that i have the listbox big enough to see all possible items if i do that
