Add data to Person or Group field type programatically

In Share point list Person or Group field is a read only field. when we trying to add logged in user to person or group field programatically, usally we capture the windows logged in user by using

txtusername.Text=System.Security.Principal.WindowsIdentity.GetCurrent().Name.ToString();

and give the captured logged in user to the person or group field. But, we get an error because person or group field is readonly field. we can add the logged in user to person or group field type using the following line

listitem["Name"] =web.Users[txtusername.Text];

using (SPSite site = new SPSite("yoursite",systoken))
{
using (SPWeb web = site.OpenWeb())
{

site.AllowUnsafeUpdates = true;
web.AllowUnsafeUpdates = true;
SPList list = web.Lists["yourlist"];
SPListItem listitem = list.Items.Add();
listitem["user Email"] = web.Users[txtusername.Text].Email;
listitem.Update();
list.Update();
web.AllowUnsafeUpdates = false;
site.AllowUnsafeUpdates = false;
}
}

Scheduled Tasks in Windows server 2008

In recent times I had run the scheduled tasks in windows server 2003 and worked perfectly, But when I am trying to run the same .exe file in windows server 2008 with scheduled tasks, I am receiving the following error "0x8004130f" in logs.

After so many trails, I have fixed the issue by running the task as Administrator. It worked fine in windows server 2008 by running as administrator.

Impersonation in SharePoint 2007

We do not have SPSecurity.RunWithElevatedPrivileges with WSS 2.0 and we have used explicit .net impersonation concepts.

using SPSecurity.RunWithElevatedPrivileges all the time will not work, In that context better using .net Impersonation.

Here's the code snippet for impersonating a different user:

SPUser user = SPContext.Current.Web.AllUsers[@"DOMAIN\LOGINNAME"];
SPUserToken token = user.UserToken;
using (SPSite site = new SPSite(SPContext.Current.Site.Url,token))
{
using (SPWeb web = site.OpenWeb())
{
SPList list = web.Lists["YourList"];
list.Items[0]["Title"] = "Your new title";
list.Items[0].Update();
}
}

Error message when you click the "Edit this Task" button on an e-mail message in Microsoft Office Outlook 2007

This is the known problem with Microsoft products and it has workaround for this problem.

following is the link from Microsoft Support about this problem.

Ghosted and Unghosted Pages in SharePoint

SharePoint web sites can contain two kinds of pages: Ghosted and Unghosted

Ghosted Page in SharePoint
A ghosted page is a page in SharePoint website which is not stored in the database instead it reference to a file which exists in the server’s file system. These reference files are common for all the website/site collection within that SharePoint server, i.e., if you modify a reference file then that change will reflect in all the websites/site collections within that SharePoint server automatically. So we can say these reference files are used as template.

The default master page of SharePoint “default.master” is a well known example of ghosted page. “default.master” page is located in the directory “C:\Program Files\Common Files\Microsoft Shared\web server extensions\12\TEMPLATE\Global”. If you do some changes in the “default.master” then this change will automatically reflect in all the websites within that SharePoint server.

To create a new site in SharePoint, a site template is used. Site template contains description of all the pages, webparts within the pages, master page used, custom lists, etc. for the web site to be created. You can define a page ghostable in the “onet.xml” file of the site template.

Unghosted Page in SharePoint
All the pages in a SharePoint website which are stored in the content database are referred as unghosted pages. All the unghosted pages are specific to that SharePoint website only, i.e., changes done in an unghosted pages will not reflect in other websites within that SharePoint server.

If a new website is created with a site template which contains a page defined as “unghostable” in the “onet.xml”, then that page will be stored in the content database of new website created and will not reference to the page available in the site template folder.

If a ghosted page is modified in the SharePoint designer, it will become unghosted. For example if a master page is customized in SharePoint Designer, SharePoint stores a modified version of the master page in the content database and also it breaks the reference to the “default.master” file on the “C:\Program Files\Common Files\Microsoft Shared\web server extensions\12\TEMPLATE\Global“.

mysites: evaluation version of sharepoint server 2007 has expired

This is not because of licensing issue. This is a sharepoint bug.

solution:

• Open up the registry editor and find the HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office Server\12.0 collection.
• Add read permissions for the WSS_WPG and Full permissions for WSS_ADMIN_WPG.
