SharePoint Important Definations

Q. What Do you know about SharePoint Object Model?

Ans. In Sharepoint Object model there are two Important namespaces, Microsoft.Office.Server and Microsoft.SharePoint . The Microsoft.Office.Server namespace is the root namespace of all Office Server objects and Microsoft.SharePoint is the root namespace for all WSS objects. Read More Here.

Q.How Does SharePoint work?

Ans. The browser sends a DAV packet to IIS asking to perform a document check in. PKMDASL.DLL, an ISAPI DLL, parses the packet and sees that it has the proprietary INVOKE command. Because of the existence of this command, the packet is passed off to msdmserv.exe, who in turn processes the packet and uses EXOLEDB to access the WSS, perform the operation and send the results back to the user in the form of XML.


Q What is CAML?

Ans: CAML stands for Collaborative Application Markup Language and is an XML-based languagethat is used in Microsoft Windows SharePoint Services to define sites and lists, including, for Eg, fields, views, or forms, but CAML is also used to define tables in the Windows SharePoint Servies database during site provisioning.

Q. What are Application Pages in SharePoint?

Ans : Unlike site pages (for example, default.aspx), a custom application page is deployed once per Web server and cannot be customized on a site-by-site basis. Application pages are based in the virtual _layouts directory. In addition, they are compiled into a single assembly DLL.

A good example of an Application Page is the default Site Settings page: every site has one, and it's not customizable on a per site basis (although the contents can be different for sites).

With application pages, you can also add inline code. With site pages, you cannot add inline code.
Typically, you link custom application pages to application.master, the master page file that is used by the default application pages in Windows SharePoint Services. You should also write application pages to inherit from a base class defined inside the Microsoft.SharePoint assembly named LayoutsPageBase.

Q. What does RunWithElevatedPrivileges do?

Ans. There are certain object model calls model that require site-administration privileges. To bypass access-denied error, we use RunWithElevatedPrivileges property when request is initiated by a nonprivileged user. We can successfully make calls into the object model by calling the RunWithElevatedPrivileges method provided by the SPSecurity class.

Q. While creating a Web part, which is the ideal location to Initialize my new controls?

Ans. Override the CreateChildControls method to include your new controls. You can control the exact rendering of your controls by calling the .Render method in the web parts Render method.
