Hey Now Everybody,
In this 9th post of the Catto Code Crackin series we’ll continue with the section ‘real world exam question concepts’. In the .NET 3.5 * the .NET 4 exam there are questions. Let’s inspect some concepts & properties that will be the skills measured.
Microsoft announced the .NET 4.0 Beta Exams on St. Patrick’s Day which are a free exam & if passed you get certified. Much of the study & prep materials are not available yet, therefore I’ve been studying for a similar exam 70-562 which is the .NET 3.5 ASP.NET Application Development. I hope by posting this content it will help myself along with other people in the community learn & get excited about .NET 4. If you are serious about studying for a MS Exam 2 must have resources: the Self Paced training books are a great books to buy along with practice exams from eBay.

QUESTION 26 JS AssemblyInfo.cs
JavaScript file named CalculatorScript.js.
function divide(a, b) {
if (b == 0) {
var errorMsg = Messages.DivideByZero;
alert(errorMsg); return null;
}
return a/b;
}
You embed the CalculatorScript.js file as a resource in a Class Library project.
The namespace for this project is Calculator.Resources.

You add an ASP.NET AJAX ScriptReference element to the AJAX Web form.
You need to ensure that the JavaScript function can access the error messages that are defined in the resource file.
You add in the AssemblyInfo.cs file the following:
C. [assembly: ScriptResource ("Calculator.Resources.CalculatorScript.js", "Calculator.Resources.MessageResources", "Messages")]

QUESTION 27 AJAX Asynchronouse Postback
AJAX-enabled Web form by using the following code fragment.

<ContentTemplate>
<asp:TextBox runat="server" ID="txtInfo" />
<asp:Button runat="server" ID="btnSubmit" Text="Submit" />
</ContentTemplate>
</asp:UpdatePanel>
<asp:UpdatePanel runat="server" ID="updSecondPanel" UpdateMode="Conditional">
<ContentTemplate> ...
