I reprogrammed the device to only send the CR and now the problem is solved. I have come to the belief that the problem we are seeing with the escape key is a bug. 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. 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. 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. Causes Validation = False Public Class Form1 Private mbln Cancel As Boolean Private Sub Text Box1_Validating(By Val sender As Object, By Val e As System. -- Al Reid "Terry" Hi Al, There is another property at the form level that affects how this stuff works - Auto Validate. 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 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" news:78**********************************@microsof .. I am new to VB comming from VB6, but that was also the case in VB6.

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. Close() End Sub Private Sub Text Box1_Validating(By Val sender As Object, By Val e As System. When you click on the button the validating event fires. If the handle matched then immediately exit the Validating event without setting e. -- Al Reid I had tried all of that, *BUT*, I had neglected to set the button's Causes Validation to False. 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. 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.

When you click on the button the validating event fires. If the handle matched then immediately exit the Validating event without setting e. -- Al Reid Well it works for me - but one thing I left out - you need to set the cancel buttons 'causes validation' to false. 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.

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. -- Terry "Al Reid" wrote: Ok, I remember now, you are using a modal msgbox in your validation code. If you were using an errorprovider, then the error would be set, the focus would be returned to the textbox, the form closing event would then fire and it changes the cancel flag to false and the form closes.
