Vb net handles validating
This is cumbersome and unnecessary for those kind of fields which have been filled automatically by barcode (see: “Kofax Capture – Document Separation and Barcodes“) or OCR , as the validity of these values can often be checked by simple rules or checks against databases.

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. 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. 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! 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.

With Kofax Capture you can enter document index values in a validation screen or just confirm or changes values which have been recognized automatically.
The validation screen form presents all fields of a document and the user has to confirm/change field values or enter data.
In this example I will show how to validate the data entered into a datarepeater control.
