Add hidden metadata field to SPListItem

You need to add a new field to the list that is marked Hidden="TRUE".


You can do this via the object model:




using (SPSite sps = new SPSite("http://someServer/"))

{

using (SPWeb spw = sps.OpenWeb())

{

SPList spl = spw.Lists["Shared Documents"];


String strNewField = "";

try

{

spl.Fields.AddFieldAsXml(strNewField);

}

catch (SPException spe)

{

// Notify error that a duplicate name was detected

}

spl.Update();

}

}



Note : These hidden field will not appear when we try to create custom view using site action.

This situation generally has a negative performance impact and may even lead to the application becoming non responsive or memory usage accumulating continually over time. To avoid this problem, all single threaded apartment (STA) threads should use pumping wait primitives ...

Subsequent articles will cover advanced topics, including more on custom actions, .NET installer classes, and how to build an upgrade for the product. Introduction Setup and deployment projects have always been a part of the Visual Studio.NET environment. Setup projects can be used to build various deployment packages, most notably Windows Installer setups packaged as MSI files. I’ll start with a basic setup that installs a C# Windows forms program and adds a shortcut to it. First, select  Setup Project , grouped under  Setup and Deployment  in the  Other Project Types  section. Choosing this will give you an empty project for adding your deployment units. With the project selected in Solution Explorer, the  View->Editor  choice gives you a selection that includes  File System  – this is where you add your files and shortcuts. Application Folder ...
