Branding SharePoint 2007

Branding SharePoint 2007 Site using CSS

In SharePoint CSS can exists at places:

* In the 12'hive in the core.css
* In the Theme folder of 12'hive depending on the theme
* In the Master Page itself, i.e. inline css
* Page referring custom css files
* Content editor webpart
* WebPart code behind

So what's the order of execution of the CSS at page render time (i.e. CSS inheritance).

Well, this is kinda complicated it depends upon bunch of factor:

* Ghosted/Unghosted Master Page
* Unghosting Core.css using SPD
* Making copy of layouts folder
* How the master page is deployed
and so on ...

As Thumb Rule to keeps things simple,easy and efficient, do the following:

* Inline CSS inside the MasterPage
* CSS for only certain pages, use content editor webpart

BTW, Use IE developer toolbar to see whats styles from CSS is finally applied to the page content.

SharePoint Custom Application Logs in the EventViewer (source code)

Custom Logging to Event Viewer by SharePoint Custom code:

using System;
using System.Collections.Generic;
using System.Text;
using System.Diagnostics;

namespace My.Foo.Bar
{
public class EventLogHandler
{
static string sSource = "My Portal";
static string sLog = "Application";                   //Change it to any specific name for categorization purpose in the Eventviewer.
//static string sEvent = "Error Occurred";

public static void AddApplicationEventLog(string exceptionDetails)
{
try
{
System.Security.Principal.WindowsImpersonationContext wic =
// make impersonation = false in the code.
System.Security.Principal.WindowsIdentity.Impersonate(IntPtr.Zero);

if (!EventLog.SourceExists(sSource))
EventLog.CreateEventSource(sSource, sLog);

if (!string.IsNullOrEmpty(exceptionDetails))
{
//EventLog.WriteEntry(sSource, sEvent);
EventLog.WriteEntry(sSource, exceptionDetails,
EventLogEntryType.Error, 234);
}
else
EventLog.WriteEntry(sSource, "No Error Message", EventLogEntryType.Information, 234);

// again roll back the Impersonation = true
//ExceptionManager.Publish(e);
wic.Undo();
}
catch (Exception e1)
{
//do nothing
}
}
}
}

Usage from your custom code, once you have the above class as a part of your application:

EventLogHandler.AddApplicationEventLog("Your message for event viewer");
The Event Viewer doesn't display the custom log message, if the application is not registered for the logging in the event viewer. To register your custom application with the eventviewer,
Run the following console application:

using System;
using System.Collections.Generic;
using System.Text;
using System.Diagnostics;

namespace EventLogWriter
{
class Program
{
static void Main(string[] args)
{
try
{
string sSource = "My SP Web Portal";
string sLog = "Application";
string exceptionDetails = "Sample Entry";
try
{
System.Security.Principal.WindowsImpersonationContext wic =
// make impersonation = false in the code.
System.Security.Principal.WindowsIdentity.Impersonate(IntPtr.Zero);

if (!EventLog.SourceExists(sSource))
EventLog.CreateEventSource(sSource, sLog);

if (!string.IsNullOrEmpty(exceptionDetails))
{
//EventLog.WriteEntry(sSource, sEvent);
EventLog.WriteEntry(sSource, exceptionDetails,
EventLogEntryType.Error, 234);
}
else
EventLog.WriteEntry(sSource, "No Error Message", EventLogEntryType.Information, 234);

// again roll back the Impersonation = true
//ExceptionManager.Publish(e);
wic.Undo();
}
catch (Exception e1)
{
//do nothing
}
}
catch (Exception ex)
{
}
}
}
}

Database Transactions in NetTier

Transactions are must when working on real time projects, always compliy with ACID properties

Try the following:

TransactionManager tran = DataRepository.Provider.CreateTransaction();
tran.BeginTransaction();
bool success = false;
try
{
// do some inserts / updates / etc
DataRepository.TicketProvider.Update(tran, ticket); //OR INSERT METHOD
UpdateSharePointLibrary(ticket.XML);
success = true;
}
Catch(Exception ex)
{
Success = false;
}
finally
{
if (success)
tran.Commit();
else
tran.Rollback();
}

If the above approach doesn't work try the one below:

try
{
using (TransactionScope scope = new TransactionScope(TransactionScopeOption.Required, TimeSpan.MaxValue))
{
//web service call
// db calls
...
scope.Complete();
}//scope

}
catch (Exception ex)
{
.....
}

SharePoint WebService Response and XML Parsing

private bool IsGroupExisting(ugWebService.UserGroup ugws, ArrayList grps)
{
bool flag = false;
try
{

System.Xml.XmlDocument doc = new System.Xml.XmlDocument();

System.Xml.XmlElement root = doc.DocumentElement;
System.Xml.XmlNodeList lst = root.GetElementsByTagName("Group");

foreach (System.Xml.XmlNode n in lst)

SharePoint Deplyoment Jobs frozen or stuck

Timer Jobs Status Stuck ..

i.e. when you check in the Centrl Admin under Solution Management, all you see is ...deploying, retracting, ...

Create a batch file and execute the following before and after the solution deployment on each application and web server in the SharePoint farm:

Content of the batch file below:
stsadm.exe -o execadmsvcjobs
sleep 15
net stop SPTimerV3
sleep 5
net stop SPAdmin
sleep 5
net start SPTimerV3
sleep 5
net start SPAdmin
sleep 5
iisreset /noforce


NOTE: Can't find sleep command. Use the external sleep command you can search for Windows Server 2008 Resource Kit or Windows Server 2003 Resource Kit
