For example, I have another application that uses a wedge type barcode reader. Maybe you should be using the Key Down event instead of the Key Press event. here is a line copied from the documentation: "The Key Press event is not raised by noncharacter keys; however, the noncharacter keys do raise the Key Down and Key Up events." My guess is that the gun is sending some noncharacter data to you.

The form's Key Preview is set to True so that I can handle key events on the form... If I connect a gun type, the program fails and the cursor jumps to a text box that has it's Tab Stop property set to False. Print in the Form's Keypress event all three methods display the exact same key codes. -- Al Reid "Terry" Hi again Al, On the barcode reader problem.

Close() End Sub Private Sub Text Box1_Validating(By Val sender As Object, By Val e As System. The code to tell if the cancel button has been clicked is: /////// Public Declare Function Window From Point Lib "user32" (By Val p As POINTAPI) As Int Ptr Public Structure POINTAPI Dim X As Integer Dim Y As Integer End Structure Private Function Cancel Button Clicked() As Boolean Dim p As New POINTAPI p. Also in the docs on Key Down there is a mention of "Is Input Key" which I will have to look into. -- Terry Well, I finally solved the barcode scanner problem. Cancel = True End If End If End Sub Private Sub Button1_Click(By Val sender As System. I just don't know what key code combination could direct focus to a text box control that should never receive focus since the Tab Stop property is false and there is no other code that sets focus to the textbox.

My guess is that the gun is sending some noncharacter data to you. -- Al Reid "Terry" Hi Al, Nearly 40 years for me since my first college FORTRAN IV class! Well, one of the keys you would not see in either the keypress or keydown events is the tab key, which of course will move the focus.

This way both the escape key and the cancel button closes the form without causing the validation to occur. I am new to VB comming from VB6, but that was also the case in VB6. To Short Date String Else Msg Box("Please enter a valid date.") e. As far as the 'gun', it may be better to write a console app. -- Terry "Al Reid" wrote: Terry, I guess we have a similar background. I don't do anything with the barcode data in the Key Press event. I guess I could inspect the data in the Key Down event to see if there is a difference. -- Al Reid "Terry" Hi again Al, On the barcode reader problem.

-- Al Reid (who didn't mean to hijack the thread) "Terry" Well it works for me - but one thing I left out - you need to set the cancel buttons 'causes validation' to false. I am new to VB comming from VB6, but that was also the case in VB6.
