Barcode scanner automatic submit - excel

Question

I already have a barcode scanner VBA function, that recognizes the barcode number, but the problem I have is that I have to click enter every time, is there any way to do it automatically and store the count in a certain column? Currently it works if I enter the same value stored in column B, it will count the records in column C, but I want to avoid hitting enter every time
This is what I got so far
Private Sub btnAdd_Click()
Dim TargetCell As Range
If WorksheetFunction.CountIf(Sheets("Sheet1").Columns(2), TextBox1.Value) = 1 Then
Set TargetCell = Sheets("Sheet1").Columns(2).Find(TextBox1.Value, , xlValues, xlWhole).Offset(0, 1)
TargetCell.Value = TargetCell.Value + 1
Else
MsgBox "Code not found"
End If
Me.Hide
End Sub

It's hard to say what you have. For example, who presses the button? Or, does your scanner enter a return. I think the code below should work under any circumstances. Please try it.
Private Sub TextBox1_Change()
Dim TargetCell As Range
Dim Qty As Long
With TextBox1
If Len(.Value) = 3 Then
Set TargetCell = Worksheets("Sheet1").Columns(2) _
.Find(.Value, , xlValues, xlWhole)
If TargetCell Is Nothing Then
MsgBox """" & .Value & """ Code not found"
Else
With TargetCell.Offset(0, 1)
Qty = .Value + 1
.Value = Qty
End With
Application.EnableEvents = False
TextBox1.Value = "Count = " & Qty
Application.EnableEvents = True
End If
.SelStart = 0
.SelLength = Len(.Value)
End If
End With
End Sub
I think you have a user form and in this form you have a text box called TextBox1. If so, the code should be in the user form's code module. If you have a text box in your worksheet paste the code to the code module of the sheet on which the text box resides.
Now, you need to adjust this line of code If Len(.Value) = 3 Then to determine when to process the data. This is because the Change event will occur whenever even a single character is entered. I tested with 3 characters. Change the number to a value equal to the length of the numbers you scan in. In theory that still leaves the CR hanging which your scanner might also send. If that causes a problem experiment with >= in place of the = in my code.
The code will add the scan to the existing quantity, just as you had it, and indicate the new total in the text box, in case you are interested. You might replace this with "OK". The code will select the text it enters. Therefore when you enter something else, such as a new scan, it will be over-written without extra clicks being required.
