Add Webpart zone on Masterpage in SharePoint

You know you can’t add a webpart zone into Master page directly, but there is tricky you can do it.

Just add

<asp:ContentPlaceHolder id="WeatherPart" runat="server"></asp:ContentPlaceHolder>

In the pagelayouts, set a control with the same id-name and place your webpartzone inside. You have to do this for every pagelayout that needs a header image in the masterpage. For each page though, there has to be added a image webpart, or whatever webpart you like. So be aware of this, if you use a webpartzone in your masterpage.

<asp:Content ContentPlaceHolderId="WeatherPart" runat="server">
    <div>
	<WebPartPages:WebPartZone runat="server" Title="WeatherPart" ID="WeatherPart"><ZoneTemplate></ZoneTemplate></WebPartPages:WebPartZone>
	</div>
</asp:Content>

MOSS 2007 RSS Viewer Error

If you receive this error “Check the logs for details and correct the problem” when you add RSS Viewer. First you need to check if Kerberos authentication has been turned on. You can follow this link.

If so, following are steps to configure proxy settings.

1. Go to web application directory generally (C:\Inetpub\wwwroot\wss\VirtualDirectories\)
2. Edit web.config using proper text editor like notepad. (I used word pad for editing and lost my application)
3. Search defaultProxy in web.config
4. Change above system.net XML tag as shown below

<proxy proxyaddress="http://:” bypassonlocal=”true”/>

5. Please make sure to place proxy address in above format http://: e.g.
http://192.186.0.1:8080 instead of 192.186.0.1:8080 otherwise you will encounter above error.

InitializeError- Failed to load the application. It was built with an obsolete version of Silverlight

You may experience this problem when you try to run an existing SilverLight project.

I only know the quick and dirty solution to this problem. (at least, it worked for my app)
You’ll have to open the .xap file with an archive program like winara. Edit the AppManifest.xaml file, and change the version number into the current number (something like 2.0.30825.0). And your program should work.

Hide left navigation panel without changing Master Page

Just found this easy solution to hide the left navigation panel in sharepoint

The left navigation bar makes the page looks very “SharePoint”. And, some valuable space is wasted under it. If you don’t want to customize the Master page (or want to keep the left nav panel in the rest of the site), you can just hide it on the home page. Insert a Content Editor webpart, and edit the source by clicking the “Source Editor…” button, and enter this:

.ms-navframe{ display:none; }

That’s right, this is just to override the default style for that section.

jQuery Ticker for SharePoint Announcement List

By using Scott Price’s code, I add a query to the CAML so it will only display annoucment which not expired.

The resource cannot be found error in SharePoint

You have sometimes this error while developping a SharePoint application :

Server Error in ‘/’ Application.
The resource cannot be found.
Description: HTTP 404. The resource you are looking for (or one of its dependencies) could have been removed, had its name changed, or is temporarily unavailable. Please review the following URL and make sure that it is spelled correctly.

Even if you have activated the possibility to see errors and trace in SharePoint (Web application web.config –> callstack=”true”, customerror=”off”, debug=”true”) you won’t have a precise indication of what ressource is missing.
So just right click your page and choose “view source”.
Bingo! :

Thread was being aborted when Response.Redirect

You see receive the “Thread was being aborted excpetion ” thrown by Response.Redirect(“Login.aspx”). There is nothing wrong with your code, and it is designed on that way.

For a workaround you can use an overload to
Response.Redirect that will pass false to the endresponse parameter to
suppress the internal call to Response.End (e.g.
Response.Redirect(“Login.aspx”, false);).

Get Login Name by Full Name

Very often you need SPUser but only have Full Name of the user. By using AD Search you can get user login name.

using System.DirectoryServices;

const string ADPATH = "LDAP://myLDAPserver,validUserforAD";
const string USERNAME = "myDomain\\myUserName";
const string PASSWORD = "myPassword";
const string DOMAIN = "myDomain\\";

public static DirectoryEntry GetDirectoryObject()
{
        DirectoryEntry directoryObject = new DirectoryEntry(ADPATH, USERNAME, PASSWORD, AuthenticationTypes.Secure);
        return directoryObject;
}

public string GetUserNameByCompleteName(string completeName)
{
            DirectoryEntry adObject = GetDirectoryObject();

            //filter based on complete name
            DirectorySearcher searcher = new DirectorySearcher(adObject);
            searcher.Filter = "displayname=" + completeName;
            SearchResult result = searcher.FindOne();

            DirectoryEntry userInfo = result.GetDirectoryEntry();

            //getting user name
            string userName = (string)userInfo.Properties["samaccountname"].Value ?? string.Empty;
            userInfo.Close();
            adObject.Close();

            return DOMAIN + userName;
}

SPUser user = web.Site.RootWeb.SiteUsers[loginName]

RunWithElevatedPrivileges tricks

SPSecurity exposes a method called “RunWithElevatedPrivileges” which gives you an option to elevate the privilege to the application pool identity under which your code is executing. Looks nice, eh?

But Wait a second!! You are not done yet. I wish it was that easy when it comes to impersonation. In order to get this method call to properly impersonate your application pool identity you need to do some more work. Basically, SPSite and SPWeb objects created outside do not have Full Control even when referenced inside the delegate (anonymous method), so you need to find out their GUID before impersonation is performed and re-create the context one more time. Finally,never forget to dispose your objects!

You basically need to create parentWeb again via creation of a new SPSite, SPWeb etc. within the RunWithElevatedPrivileges block.

//Don’t dispose the following two objects. Sharepoint will take care of their disposal when page is completely rendered.
SPWeb webInUserContext = SPContext.Current.Web;
SPSite SiteInUserContext = SPContext.Current.Site;

Guid webGuid = webInUserContext.ID;
Guid siteGuid = SiteInUserContext.ID;

SPSecurity.RunWithElevatedPrivileges(delegate()
{
// get the site in impersonated context
using (SPSite site = new SPSite(siteGuid))
{
// get the web in the impersonated context
SPWeb web = site.OpenWeb(webGuid);
web.AllowUnsafeUpdates = true;
// Do your work here

web.Dispose();
}
});

Cannot open log for source *. You may not have write access.

1. Click Start -> Run and type: regedit
2. Click Ok
3. Locate: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\ Eventlog\Application
4. Modify CustomSD to give all users read/write access to the Application event log by appending the string (A;;0×3;;;AU) to the CustomSD entry.

For example

O:BAG:SYD:(D;;0xf0007;;;AN)(D;;0xf0007;;;BG)(A;;0xf0007;;;SY)(A;;0×7;;;BA) (A;;0×7;;;SO)(A;;0×3;;;IU)(A;;0×3;;;SU)(A;;0×3;;;S-1-5-3)(A;;0×3;;;AU)
