When you wish to handle events for your page, you will need to update your <script> block or code-behind file with an appropriate event handler. As you have just seen, by default VB 2005 pages make use of the Handles keyword for this purpose. However, if you examine the <%@Page%> directive, you will notice a specific attribute named AutoEventWireUp, which by default is set to false: <%@ Page Language="VB" AutoEventWireup="false" CodeFile="Default.aspx.vb" Inherits="_Default" %> With this default behavior, each page-level event handler must make use of the Handles keyword to inform the runtime you are interested in capturing the event in question. By way of a simple test, if you were to comment out the Handles clause of your Load event as follows: Protected Sub Page_Load(ByVal sender As Object, _ ByVal e As System.EventArgs) ' Handles Me.Load ' Perform load logic here... End Sub you would now find that the page no longer emits the In Load Event! message. However, if you were to enable AutoPageWireUp by setting this attribute to true: <%@ Page Language="VB" AutoEventWireup="true" CodeFile="Default.aspx.vb" Inherits="_Default" %> the Load event handler is still invoked, even though the Handles keyword has been omitted. As its name suggests, this attribute (when enabled) will generate the necessary event riggings within the autogenerated partial class described in earlier in this chapter. By and large, you will seldom (if ever) need to enable the AutoEventWireup attribute, as the IDE will always add the necessary Handles clause to your page-level events.

Ocrad. js - Optical Character Recognition in Javascript - Kevin Kwok
Ocrad. js . Optical Character Recognition in JS . Ocrad. js is a pure- javascript version of Antonio Diaz Diaz's Ocrad project, automatically converted using Emscripten. It is a simple OCR ( Optical Character Recognition ) program that can convert scanned images of text back into text.

s The limitations for asymmetric key encryption and decryption on SQL Server are the same as those Tip

One of the advantages of this system is that it s very economical. For example, if the value of a property has not been set locally, Silverlight will retrieve its value from the template or a style. In this case, no additional memory is required to store the value. Another advantage is that different property providers may override one another, but they don t overwrite each other. For example, if you set a local value and then trigger an animation, the animation temporarily takes control. However, your local value is retained and when the animation ends it comes back into effect.

Another event that may occur during your page s life cycle is Error, which also works in conjunction with the System.EventHandler delegate. This event will be fired if a method on the Page-derived type triggered an exception that was not explicitly handled. Assume that you have handled the Click event for a given Button on your page, and within the event handler (which I named btnGetFile_Click), you attempt to write out the contents of a local file to the HTTP response.

OCR Tags - CVISION Technologies
What are Tags , OCR Description. Tags refer to keywords or labels that relate to particular information. OCR tags are numerous- available online, for user download and information feed.

Also assume you have failed to test for the presence of this file via standard structured exception handling If you have rigged up the page s Error event, you have one final chance to deal with the problem on this page before the end user finds an ugly error Consider the following code: Partial Class _Default Inherits SystemWebUIPage Protected Sub Page_Load(ByVal sender As Object, _ ByVal e As SystemEventArgs) Handles MeLoad ' Perform load logic here.. End Sub Protected Sub Page_Error(ByVal sender As Object, _ ByVal e As SystemEventArgs) Handles MeError ' Gut the current response, issue an error, ' and tell the runtime the error has been processed ResponseClear() ResponseWrite("I am sorry..I can't find a required file") ServerClearError() End Sub Protected Sub btnPostback_Click(ByVal sender As Object, _ ByVal e As SystemEventArgs) Handles btnPostback.

2 introduced a special type of dependency property called an attached property. An attached property is a full-fledged dependency property and, like all dependency properties, it s managed by the Silverlight property system. The difference is that an attached property applies to a class other than the one where it s defined. The most common example of attached properties is found in the layout containers you saw in 3. For example, the Grid class defines the attached properties Row and Column, which you set on the contained elements to indicate where they should be positioned. Similarly, the Canvas defines the attached properties Left and Top that let you place elements using absolute coordinates.

Listing 8-10 demonstrates the use of asymmetric key encryption and decryption functions. The results are shown in Figure 8-4. Listing 8-10. Encrypting and Decrypting with Asymmetric Keys -- Create DMK CREATE MASTER KEY ENCRYPTION BY PASSWORD = 'P@55w0rd'; -- Create asymmetric key CREATE ASYMMETRIC KEY TestAsymmetricKey WITH ALGORITHM = RSA_512;

Click ' This is just here to allow a postback End Sub Protected Sub btnTriggerError_Click(ByVal sender As Object, _ ByVal e As SystemEventArgs) Handles btnTriggerErrorClick ' Try to open a nonexistent file on the web server ' This will fire the Error event for this page SystemIOFileReadAllText("C:\IDontExisttxt") End Sub End Class Notice that your Error event handler begins by clearing out any content currently within the HTTP response and emits a generic error message If you wish to gain access to the specific SystemException object, you may do so using the HttpServerUtilityGetLastError() method exposed by the inherited Server property: Protected Sub Page_Error(ByVal sender As Object, _ ByVal e As SystemEventArgs) Handles MeError ResponseClear() ResponseWrite(StringFormat("The error was: <b>{0}</b>", _ ServerGetLastError()Message)) Server.
