VB.NET barcode reader code sample shows reading bar code value from JPG image with Bytescout Barcode Reader SDK. As we explain in a moment, for this validation to take place, the action page for the form must be a ColdFusion template, and more importantly, it must already exist. If you try to submit this form without an existing action page (in our case, login_action.cfm), you don t get a validation error but instead a file not found error. Create a blank template called login_action.cfm. It need have no code in it at all. Of course, you add code to it later to perform the check to actually authenticate the user s login attempt. We explain why it must exist and be a ColdFusion template for the validation to take place. 16 Assuming that the action page has been created, if the user fails to provide a value, he receives the error shown in Figure 20-2. vb.net symbol.barcode.reader Windows 8 .

Figure 20-2: The validation error message for a required field. Notice a couple important things: First, all you did was add a hidden field to the form. And you need to be clear on this fact: HTML has no native support for using a hidden field to perform validation this way. As far as the form is concerned, it s just another hidden field on the form. This really is a bit of magic that ColdFusion is performing. for security in the so-called body sensor network (BSN) settings [10 12]. In this emerging area of research, the relevant ECG techniques ostensibly appear to be mere examples of ducial methods. Indeed, the relevant ECG feature in a BSN is the socalled interpulse interval (IPI) sequence [3], which is a sequence of times between R R intervals. In other words, it measures a sequence of times between heartbeats (similar to that in a tachogram), which is a ducial characterization. However, as will be examined subsequently, the speci c requirements for a BSN (e.g., with respect to simultaneous data acquisition) deviate signi cantly from those needed in standard ducial methods. In some sense, while ducial methods typically rely on the averaging (i.e., statistical ensemble) of values due to ECG features, it is the extraction of an instantaneous stochastic realization that is relevant to a BSN. 16.3.3.1 Body Sensor Network (BSN) Motivations Note Developers familiar with ColdFusion 5 and previous releases may notice that the look and feel of the validation error message has changed slightly, with the gray box surrounding the message and the available hyperlink to go back to the previous page.
