If I hit the escape, the validation event fires and since the m Canceling is not True, the validation error gets displayed before the form closes. As far as the original validation issue, I started a new project (VB2005) and tried your approach It works except that pressing the Esc key still causes the validation event to fire. The gun was putting out a LF after the CR and in the Key Down event it showed up as a Keys. Validating If Not mbln Cancel Then Dim dte Date As Date Time If Date Time. I have come to the belief that the problem we are seeing with the escape key is a bug. -- 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.

The thing that this approach does not allow (unless I've one again neglected the obvious) is using the escape key to trigger the form cancel. Y Dim HWnd As Int Ptr = Window From Point(p) If HWnd = CType(Me. Handle Then Return True Else Return False End If End Function \\\\\\ -- Al Reid "Al Reid" I had tried all of that, *BUT*, I had neglected to set the button's Causes Validation to False. I reprogrammed the device to only send the CR and now the problem is solved. -- Terry "Al Reid" wrote: 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. Also in the docs on Key Down there is a mention of "Is Input Key" which I will have to look into. -- Terry Hi Al, There is another property at the form level that affects how this stuff works - Auto Validate.

Darin *** Sent via Developersdex Yes, closing the form causes 'validating' to take place. I have come to the belief that the problem we are seeing with the escape key is a bug.

One, remove the "control Box" from the form, so the user cant close it that way. in the btn Cancel_Click event: Removehandeler Text Box1.validating, Addressof Text Box1_Validating -- Terry "Darin" wrote: I know that, but the problem is when the user clicks EXIT, the textbox.validating event is called BEFORE the cancel.click is done, so the textbox is being validated. According to the documentation: "The cancel button for a form is the button control that is clicked whenever the user presses the ESC key." Which says to me the behavior s/b the same! To Short Date String Else Msg Box("Please enter a valid date.") e.

I have a form w/ a textbox and Cancel button on it. When I click on the cancel button it doesn't even get to the cancel.click event until AFTER it has done the validating.

Validating If Not mbln Cancel Then Dim dte Date As Date Time If Date Time. Also note that the "trick" to closing the form is not keeping a seperate "canceling" flag, but to put "e.cancel=False" in the forms closing event.

I have a routine to handle textbox.validating, and I have the form setup so the Cancel button is the Cancel button. I am going to start a new thread - calling it a bug and see what happens. Down (Down Arrow) and some how (and I never figured this one out) the next control in the tab order, regardless of the Tab Stop property, got focus.

My final solution, unless someone has a better suggestion, is to change the Validating event to the Leave event and detecting whether the cancel button had been clicked in the Leave event and exiting if it was. 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. 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. Why it would stop on a textbox with tabstop property set to False - I have no idea, unless it is a behavior of the container its in.

One, remove the "control Box" from the form, so the user cant close it that way. in the btn Cancel_Click event: Removehandeler Text Box1.validating, Addressof Text Box1_Validating -- Terry That doesn't work either, at least not for VB2005. Then in the btn Cancel_click event, either set a module level variable like m Canceling to True and then in the validating event ... I've been fighting the same problem for some time now. I think that the only way to do this is to grab the mouse coordinates in the validating event, do a Window From Point API call, then compare the returned HWND to the Cancel Button's Handle. I also got the Window From Point approach working as well. The following code works as you might hope: Public Class Form1 Private m Canceling As Boolean = False Private Sub Button1_Click(By Val sender As System. Private Sub Text Box1_Validating(By Val sender As Object, By Val e As System. As far as the 'gun', it may be better to write a console app. -- Terry "Al Reid" wrote: Terry, 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. news:78**********************************@microsof .. I am new to VB comming from VB6, but that was also the case in VB6. I added the code to handle the esc key per the "bug" thread and it works.

However, after I removed the "canceling" flag and added the "e.cancel=False" to the form's Form Closing event, I once again see the validation when clicking on the cancel button, but the form then closes after displaying the validation error. -- Al Reid "Terry" Hi Al, Don't know if you have been following the thread I started about the escape key "bug", but if you search this community for "Cancel Button vs Escape Key", you can see the result including the work around for the escape key.
