MCPD .NET 4 Preparing for the Microsoft beta exam 70-519 - Code Crackin #19

Hey Now Everybody,

Preparing for the Microsoft MCPD .NET 4 beta exam 70-519. This is the next version of the 3.5 70-564 exam. The MCTS exams have the self paced training kit books which are stellar resources to study from, however the MCPD exams there isn’t as much exam prep materials. Outlined are the skills measured in this exam.

This is posted to help people & myself study for the exam & learn more about .NET 4. Below are some key points that I’ve summarized so we can just read basically one or two sentences which will cover one topic or concept. I’ve tried to present this content in a way to use our time most efficiently with not much repetition and content we we use.

70-564 / 70-519 / 71-519
Key Concepts:

331 AD Authentication mode & identity Impersonation such as <authentication mode="Windows" /><identity impersonate="true" />

332 Master pages & webconfig specifies master page for application

333. DataSources for example LinqDataSource, when data's being retrieved by a datacontext object

334. Prevent harmful scripts being stored in sql db we can ValidateRequest attribute of the @Page directive should be set to false & saving the text to the database, you should make use of the Server.HtmlEncode method

335. Verifying data inputted into db is valid by when the Page.IsValid property is True use the Click event handler of the
   Button control to submit the data

336  Store data for lifetime of app we can use In-memory of the Web server process should be used as the storage.

337. Web Apps -When pages are updated frequently & we want quick startup time we precompile the application along with the fixed assembly names by using the aspnet_compiler utility.

338. Ensure updating pages doesn't effect load time of other pages we use a Web site project copy the entire application to the deployment server and copy only the updated files to the server.

339. Multiple master pages with user controls to dynamically reference the control we:
    Code each master page class to implement a common interface exposing the ImageUrl property of the Image control
   create a strongly typed master page reference by using the @ MasterType directive on each content page

4110 Upgrading applications by upgrade the application to a Visual Studio 2010 Web application project

4111 AD auth - When an unauthenticated user hits a page we want to force them to enter uid & pw we use of Forms authentication.Use the ActiveDirectoryMembershipProvide class

4112 when a data bound control which we can page through records, create, update we can use a FormView

4113. When a page displays data from a db based on an id & not creating a new node in the sitemap for each page we can handle the SiteMap.SiteMapResolve event

4114. When we want to display data in a grid we retrieve data for the GridView control by using the SqlDataSource control

4115. When a control supports 2 languages such as all German-region views in German all others in english we can for each page without any culture specified & ge culture, create a resource file place the files in the App_LocalResources directory

4116. Consistent display properties of controls we define a skin for each type of ASP.NET server control that is used in the app

4117. A DAL supporting 3rd party vendors the data access object we use OleDbDataAdapter

4118. Deploying an app ensure assemblies comply w/ rules & naming conventions we create a Web app project, the output assembly name should be set to conform to the rules.

4119 Excel files in a folder that we don't want accessed from bots we have each the Excel files should be mapped to the ASP.NET ISAPI filter & a <deny> element should be added to the <authorization> element in the Web.config file

4120. When a firewall denies access on ports 80 & 443 we use the Secure Sockets Layer (SSL) on port 443 to expose the Web services.

8221. Databound server control that uses customized item templates & uses the DataPager we use a ListView.

8222. when subdirctories are permission based by roles & stored in a single web.config file we'd use the <location> node.

8230. Validate against AD by client side script. code fragment should be added to the Web.config file of the application <authentication mode="Forms" />
configure the application, making it use the ActiveDirectoryMembershipProvider class.

8231. Implementing a master page we can:
  set the MasterPageFile property on each page to the virtual path of the master page file
& configure a virtual directory within each app, and point the virtual directory to the folder containing the master page
& copy the master page into a single folder on the server

8232 Modify & update data that is retrieved from a data set. using SQLCommandBuilder the update command for related SQLDataAdapter class we'd after the UpdateCommand property of the SqlDataAdapter class is set to a SqlCommand object, we use a custom UPDATE statement and call the Update method of the SqlDataAdapter class

8233. Performance issues occur & we collect sample timings of pages. We set the enabled attribute to true and the pageOutput attribute set to false for the Web.config's trace element
Trace Element - enabled attribute = true & pageOutput attribute = false

8234 Photo sharing app to download the image, first we ascertain the request for the photo download by creating an HttpHandler class, then process photo for format & return photo

8235.  DB accessed by web app, web & sql servers on separate servers we create a Web service, deploy it to the same network as the database server

8236 Application_error event: Create tracking number for errors after the exception is logged in the Application_Error event of the Global.asax file, we redirect to the customError.aspx page, pass tracking number in query string.

8237 Set up Authentication for a subdirectory add this code to the Web.config in the subdirectory.
<allow roles="TomatoSubscriber" />
<deny users="*" />

8239 Web form calls web service when page is accessed ensure two routines are called we have  Async="True" attribute has to be added to the Page directive.

3440.   Deploy app to server where there are more than one app is & the app is the only one that can modify certain files on the server,  After the application pool is configured to use a dedicated user account, we give access for the share to the user account.

3441. AddFileDependency When a batch process updates a xml file code segment: Response.AddFileDependency(fileDependencyPath);Response.Cache.SetCacheability(HttpCacheability.Public);

3442. Create a control in VS10 toolbox we'd use a custom server control
