Active Directory group in sharepoint

what is the best approach for assigning permission levels in SharePoint?
One recommendation is to use AD groups or SharePoint groups that contain AD groups rather than individuals to control access. It's much easier to clean up AD group membership when an individual leaves than to track down all the places where you've given them individual access (including membership in SharePoint groups).

How to deploy Office Shared Add-in

Suppose you have implemented shared add-in using VS 2008 for Office 2007 and now you have to create installation package.

unable to create specified activex control Office add-in error

Add-ins that directly implement ICustomTaskPaneConsumer expose one or more ActiveX controls that you must register. To use the test add-in for ICustomTaskPaneConsumer, you can either rebuild the add-in, which registers it, or simply register the add-in assembly that contains the managed ActiveX control. You must also be sure to rebuild or re-register the shim, so that the shim registration overrides the add-in registration.

_spbodyonloadfunctionnames is undefined Javascript Error in sharepoint

_spBodyOnLoadFunctionNames: Generally, ASP.NET 2.0 Master page concept is used for sharepoint pages and the “body ” is defined in master page. So, the content page is not able to add function to the body’s onload event directly. In order to work around this limitation, SharePoint provides the “_spBodyOnLoadFunctionNames” array. When the body is loaded, the onload event handler executes each function whose name is contained in this array. We added “myFunction” to the array so that it would run when the body’s onload event fires.
_spBodyOnLoadFunctionNames.push("myFunction ");
