Difference between .dwp(moss 2007) and .webpart(sharepoint 2010) ?

Posted By :Sagar Pardeshi     Posted Date :August 12, 2013    Points :40   Category :SharePoint 
The difference is .dwp was the file extension used in version 2 of SharePoint and .webpart is a new extension used in version 3. Inside the files, the schemas are different and it is indicated as such by the version number on the xmlns attribute.

Here is an example of a version

DWP
webpart description(dwp) extention was used in WSS 2.0
The schema file describes it like...
<WebPart xmlns="http://schemas.microsoft.com/WebPart/v2">
The elements/attributes names written are not standardized, you can define your tag as what you want


Webpart
the new extention available on WSS 3.0
The schema file describes it like...
<webPart xmlns="http://schemas.microsoft.com/WebPart/v3">
The elements/attributes names are standardized. For example the property element
<properties>
<property name="Title"




The main difference is that all properties passed to the web part are specified with a property element and a name attribute in version 3.Version 2 uses different element names for everything

What is the difference between Microsoft Office SharePoint Server 2007 for Internet sites and Microsoft Office SharePoint Server 2007?

  
Microsoft Office SharePoint Server 2007 for Internet sites and Microsoft Office SharePoint Server2007 have identical feature functionality. While the feature functionality is similar, the usage rights are different.If you are creating an Internet, or Extranet, facing website, it is recommended that you use Microsoft Office SharePoint Server 2007 for Internet sites which does not require the purchase client access licenses. Websites hosted using an "Internet sites" edition can only be used for Internet facing websites and all content, information, and applications must be accessible to non employees.Websites hosted using an "Internet sites" edition cannot be accessed by employees creating, sharing, or collaborating on content which is solely for internal use only, such as an Intranet Portal scenario.

What is the difference between System.Web.UI.WebControls.WebParts.WebPart and Microsoft.SharePoint.WebPartPages.WebPart?

  
Microsoft.SharePoint.WebPartPages.WebPart is provided in MOSS 2007 to provide backwards compatability with MOSS 2003 webparts. In MOSS 2007, it is recommended to use System.Web.UI.WebControls.WebParts.WebPart instead.

What are the two base classes a WebPart you are going to use within SharePoint 2007 can inherit from?

  
There are two base classes that a WebPart which is going to be consumed by SharePoint can inherit from, either the
SharePoint WebPart Base class
or the
ASP.NET 2.0 WebPart base class.
When inheriting from the SharePoint WebPart Base class your derived WebPart class will inherit from Microsoft.SharePoint.WebPartPages.WebPart. When inheriting from the ASP.NET 2.0 WebPart base class your derived WebPart class will inherit from System.Web.UI.WebControls.WebParts.WebPart. It is considered good practice to use the ASP.NET WebPart base class since the old base class is meant for backwards compatibility with previous version of SharePoint, however there are four exception when it is better to leverage functionality from the SharePoint WebPart base class:
Cross page connections
Connections between Web Parts that are outside of a Web Part zone
Client-side connections (Web Part Page Services Component)
Data caching infrastructure
(More...)

Which points we need to consider while migrating SharePoint application from 2007 to 2010?

  
While migrating SharePoint application from 2007 to 2010, we need to consider or look at or check the following points:
1) Absolute Classes and Namespaces - Because the changes in the API in the upgrades are backward compatible, we don't have to make any changes to 2007 custom solutions before we redeploy them to the 2010 version of the SharePoint.
Some classes and namespaces are absolute but they will continue to work as expected.We need to recompile our code. The compiler warning will tell us which elements of the object model are absolute and which newer alternatives we should use.

2) Event Handler - We need to recompile and redeploy it.

3) Master Page and Themes - SharePoint 2007 themes no longer exist in SharePoint 2010 so any customization and design work that we have done with themes will not be imported into the new version.

4) Scripts - Scripts should work with 2010, but we should check to determine whether they are relevant to the new changes.

5) 32 bit DLLs - DLLs that support 32 bit application will no longer be supported in SharePoint 2010 as it is designed to work in 64 bit. (More...)
