We've bound a K2 process to an InfoPath document. The InfoPath document is created using Visual Studio and uses C#. A submit button is added to the form by K2.

(1) Is it possible to override the OK button (that says the form has sucessfully been submitted) so that it doesn't appear? We don't want a confirmation window.

(2)Is it possible to override the error messages for the Submit button so we can make them more user friendly, or handle the errors differently?

(3) Is it possible to disable/reenable the Submit button for a form during a workflow process instance? For example at activity A we want the submit button disabled, but at Activity B it should be reenabled and then at Activity C it should be disabled again ...

Thanks!
