*Resolved * Looping If lstbox Not Visible

Hello,

I have a textbox when double clicked displays a lstbox for a selection, but sometimes the user will manually enter something in the txtbox. So how can I loop through the lstbox to compare the entry to the txtbox without showing the lstbox.

VB Code:

For x = 0 To List1.ListCount - 1
If Text1.Text Like List1.List(x) Then
'do something
End If
Next

I trust you can make it invisible.

You could loop through the values but you don't need to.

VB Code:

Public Declare Function SendMessageString Lib "user32" Alias "SendMessageA" _
                      (ByVal hwnd As Long, _
                       ByVal wMsg As Long, _
                       ByVal wParam As Long, _
                       ByVal lParam As String) As Long
Public Const CB_FINDSTRING = &H14C ' This is for a combobox
Public Const LB_FINDSTRING = &H18F
 
        Dim lngRetVal As Long
 
        lngRetVal = SendMessageString MyListBox.hwnd, _
                                      LB_FINDSTRING, -1&, _
                                      Text1.Text)
        ' lngRetVal is the ListIndex
        If lngRetVal > -1& Then
            ' It's in the list and lngRetVal is the ListIndex
        Else
            ' It's not in the list
        End If

Thank you for your replies, but can someone tell me why this won't work.

txtReason.Text = "DE"
lstReason has several items
but one is "DE: Description"


[code]
txtReason.Text = UCase(txtReason.Text)
For i = 0 To lstReason.ListCount - 1
tmp = Trim(txtReason.Text)
lst = lstReason.Text
cnt = InStrRev(lst, ":")
lst = Left(lst, cnt - 1)
If tmp = lst Then
bPass = True
GoTo Jump_Out
Else
bPass = False
End If
Next i
Jump_Out:
If Not bPass Then
lblMsg.Caption = txtReason.Text & "is not a valid Reason"
txtReason.SetFocus
End If
[code]

what are tmp and lst values?

Just variables to hold the value I could do it straight out, but I have a bad habit of doing things the hard way. I am trying to break up the string and pull the first 2 values to compare.

VB Code:

txtReason.Text = Trim(UCase(txtReason.Text))
    For i = 0 To lstReason.ListCount - 1
        lst = lstReason.List(i)
        cnt = InStrRev(lst, ":")
        lst = Left(lst, cnt - 1)
        If tmp = lst Then
            bPass = True
            Exit For
        Else
            bPass = False
        End If
    Next i
    
    If Not bPass Then
        lblMsg.Caption = txtReason.Text & "is not a valid Reason"
        txtReason.SetFocus
    End If

Thank you it works great.
