My guess is that the scanner is passing and extra &quot;newline&quot; character. &nbsp;The way to find out is to intercept and display every character passed in:<br />
<br />
Private sub txtBarcodeInputField_KeyPr<wbr />ess(KeyAsc<wbr />ii As Integer)<br />
&nbsp; dim i as integer<br />
&nbsp; for i=1 to len(KeyAscii)<br />
&nbsp; &nbsp; debug.print mid$(KeyAscii,i,1)<br />
&nbsp; next i<br />
end sub<br />
<br />
Run the same test and see what the last few characters are. &nbsp;If they're 13 and 10, you're getting a carriage return and line feed at the end, which may not have been expected.<br />

My guess is that the scanner is passing and extra "newline" character.  The way to find out is to intercept and display every character passed in:

Private sub txtBarcodeInputField_KeyPress(KeyAscii As Integer)
  dim i as integer
  for i=1 to len(KeyAscii)
    debug.print mid$(KeyAscii,i,1)
  next i
end sub

Run the same test and see what the last few characters are.  If they're 13 and 10, you're getting a carriage return and line feed at the end, which may not have been expected.

Thanks rspahitz, but I resolved the issue by using a doevents before the error message so I am now closing the question.

I am using a keyboard wedge barcode reader but am experiencing difficulty in displaying errors. If I use the barcode scanner it skips the first error message and displays the second. &nbsp;If I use the keyboard to input the barcode it displays the first error message. Any ideas why?

Visual Basic is Microsoft’s event-driven programming language and integrated development environment (IDE) for its Component Object Model (COM) programming model. It is relatively easy to learn and use because of its graphical development features and BASIC heritage. It has been replaced with VB.NET, and is very similar to VBA (Visual Basic for Applications), the programming language for the Microsoft Office product line.
