Hi Lorenzo,

many scanners have an option to include a TAB or ENTER after a code is
scanned ... check to see if yours has that feature and let the scanner
add it

Warm Regards,

Instead of using the AfterUpdate event, try using OnChange event.

Private Sub ScanWO_Change()
'1) Check to see if you have received a complete barcode.

IF Len(ScanWO) < TheTotalLengthOf YourBarcode THEN EXIT SUB

'2) If all digits of the barcode is received, setup ScanWO for proecssing
ScanWO.Value = ScanWO.Text

'Your code follows....

On Error GoTo Err_ScanWO_Click

'To get only WOs
WOnumber = Mid([ScanWO], Len([ScanWO]) - 17, 7)

'To find the record stored in the DispatchTable
Dim rs As Object
Set rs = Me.Recordset.Clone
rs.FindFirst "[WO_ID] = " & WOnumber
If Not rs.EOF Then Me.Bookmark = rs.Bookmark

Exit_ScanWO_Click:
Exit Sub

Err_ScanWO_Click:
'MsgBox Err.Description
'Messaje omited
'created new message when the WO does not exist
MsgBox "Error, please check if the WO scanned is on the DB!",
vbCritical, "Error, WO not found!"
Resume Exit_ScanWO_Click
End Sub

Sorry the Check length of barcode received code should be change from ..

IF Len(ScanWO) < TheTotalLengthOf YourBarcode THEN EXIT SUB

to

IF Len(ScanWO.Text) < TheTotalLengthOf YourBarcode THEN EXIT SUB

My mistake!

Most scanners can be configured to automatically output either an <enter> or
<tab> after each scan. That is how all of ours work.
