MOSS Site Navigation – Obtain Page layouts programmatically 

Here is the code snippet that will help you obtain the site navigation structure of an existing site (this will be useful when you are trying to automate deployment of site structure to the target server)

Assuming web is of type SPWeb, SW is StreamWriter that writes to a xml file

 PublishingWeb pubWeb = PublishingWeb.GetPublishingWeb(web);
            
   try
      {
          if (PublishingPage.IsPublishingPage(pubWeb.DefaultPage.Item))
          {
               SW.WriteLine("<page site=\"");
              \\ this will give you the site page name
              SW.Write(web.ServerRelativeUrl.Remove(0, 1));
              SW.Write("\" pagelayout=\"");
              \\ this will give you the Page layout name
              SW.Write(PublishingPage.GetPublishingPage(pubWeb.DefaultPage.Item).Layout.Name);
              \\ this will give you the Page title
              SW.Write("\" title=\"");
              SW.Write(pubWeb.DefaultPage.Title); 
              SW.WriteLine("\" />");

  
           }
      } 

I have left out the exception handling part and other detailed code. This is just to give you an idea about the methods available with the PublishingWeb object that will fetch you the site names/page layouts/title details.

Remember, this code snippet has to be called recursively for each SPWeb available under SPWeb.Webs

Code Metrics in VS 2008

 I am not sure whether you have tried the Code Metrics tool in VS 2008. It is a very handy tool and simply answers the question "How difficult is your code to maintain?"

You need to know how to interpret different code metrics to take corrective actions:

Maintainability Index — Should be high as possible. 100 is the target you want to achieve. This index is an aggregate of all the code metrics indexes (code complexity, lines of code, inheritance depth and class coupling)

Cyclomatic Complexity — Number of branches your code takes (switch, case, if statements). You want to keep this number low.

Depth of Inheritance — Inheritance chain. You want to keep this value as low as possible. Every time you inherit, the value goes up by 1. You want to avoid the bad cascading effect (Poorly designed class will cause the entire inheritance chain difficult to maintain)

Class coupling — this shows the dependency between different class types. If this number is higher, it means your code will become difficult to maintain. Just imagine you had numerous classes calling each other methods without any discipline.

Lines of Code — Keep a tab on the number of lines of code you have to write. With the advancement of tools and technologies, people are moving towards lesser number of codes. Keep in mind the line of code does not include the number of lines used for attribute definition, comments declaration and constructs.

There is no hard and fast rule on what the code metrics index value should be. Your project can be complex and the index numbers could be high.

An insight into code metrics will help you identify the problem areas and help you refactor code if needed.

Let us take a performance snapshot on using Row Constructors in SQL 2008

Example table:

create table Customer
(customerID int primary key clustered identity(1,1)
,firstName varchar(30)
,lastname varchar(30)
, age int
)

— SQL 2005 method

begin transaction
insert into customer values ('Joe', 'Smith', 35)
insert into customer values ('Jane', 'Smith', 36)
insert into customer values ('Daniel', 'Smith', 37)
insert into customer values ('Daniel', 'Smith', 37)
commit transaction;

— SQL 2008 method (row constructors)

begin transaction
insert into customer values
('Joe', 'Smith', 35),
('Jane', 'Smith', 36),
('Daniel', 'Smith', 37),
('John', 'Smith', 38)
commit transaction;

As you examine the different variables, you will notice that SQL 2008 Row constructor method fares much better for the scenario described.

You may come across situations where you need to add custom styles (css) to edit text inside your content editor web part. To enable custom styles to you web part, open your master CSS file used for your site and add an entry that follows the naming convention of

.ms-rteCustom-xxxx

where xxxx is the custom name of your style.

Note: When you add custom style entries to your CSS file, the content editor will override the existing styles (ArticleByLine,ArticleHeadline,ArticleTitle) and only show the custom styles you had created.

.ms-rteCustom-SampleTitleByTK

{   

font-weight: bold;

font-family: Arial   

font-size: 14pt   

color: #8F2031;   

text-transform: capitalize;

}

Once this link is added, you will see the option available in your content editor web part as shown below

I had a requirement to show the top 3 of news listing on the home page with the option of having these links open up in a new window.

First read these 2 good articles

http://blogs.msdn.com/ecm/archive/2006/10/25/configuring-and-customizing-the-content-query-web-part/

http://www.heathersolomon.com/blog/articles/customitemstyle/

Now, when it comes to locating the internal name and the field type, you may encounter some issues. Refer to Heather Solomon blog where she has some pointers.

1) Create a site column named "OpenInNewWindow" and make that a choice type with values "true" and "false"

2) Create all other site columns as required.

3) Include the site columns in your custom list.

4) Edit ItemStyle.xsl and include the following lines in your template section

        <xsl:variable name="LinkTarget">   

<xsl:if test="@OpenInNewWindow = 'True'" >_blank</xsl:if>

        </xsl:variable>

 

You will then be able to use this variable in your <a href> reference target target="{$LinkTarget}"  

Once you create a new item in your list and set the OpenInNewWindow variable, the link will open in a new window if value is set to "true".   

Row Constructors in SQL 2008

Let us delve into using Row Constructors

Two basic tables for test purposes

Customer

IF  EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID(N'[dbo].[Customer]') AND type in (N'U'))
DROP TABLE [dbo].[Customer]
GO
create table Customer
(firstname varchar(30)
,lastname varchar(30)
)

Customer1

IF  EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID(N'[dbo].[Customer1]') AND type in (N'U'))
DROP TABLE [dbo].[Customer1]
GO
create table Customer1
(firstname varchar(30)
,lastname varchar(30)
, age int
)

Use with INSERT statement to insert multiple rows as an atomic operation:

— SQL 2005 method
insert into Customer (FirstName, LastName) values (Alex, 'Smith')
go

insert into Customer (FirstName, LastName) VALUES ('John', 'Smith')
go

— another SQL 2005 method

insert into Customer (FirstName, LastName)
select 'Alex', 'Smith'
union all
select 'John', 'Smith'

— Rewriting with SQL 2008

INSERT INTO Customer (FirstName, LastName)
VALUES
 ('Alex', 'Smith'),
 ('John', 'Brown'),
 ('Daniel', 'Williams');

Using Row Constructors as a DataSource – On the Fly!

SELECT *
  FROM
     (
       VALUES

       ('John','Smith')

      ,('Alex','Smith')

     ) Customer(FirstName,LastName)

As  you see above, I just created a datasource named Customer on the fly. Try running this and you will see that the datasource is treated as a table here (not created on SQL Server though).

 

Another example of Row constructors as data source

select c.firstname
, c.lastname
from Customer c
join
(
 values('John','Smith'),('Mary','Smith'),('John','Williams')
) customerTemp(FirstName,LastName)
on c.firstname = customerTemp.firstname 

Ability to include scalar subqueries as elements in row constructors

insert into Customer1
values
('Alex','Smith',30),
('Robert','Smith',35)

insert into Customer(firstname, lastname)
values(
(select top 1 firstname from Customer1),
(select top 1 lastname from Customer1)
)

I will try to do some benchmarks on using Row Constructors on my next post.

Once TFS installed, the quickest way to validate it is working well is by creating a test Team project. You can use any existing templates (Agile/CMMI). Once the process is completed, try to view the Team project portal. Check SQL Reporting services for any errors.

After the intial steps are done, query the following url

1) Check the TFS Service:

Assuming localhost is my server and 8080 is the port

http://localhost:8080/services/v1.0/serverstatus.asmx

2) Check the Version control repository

http://localhost:8080/VersionControl/v1.0/repository.asmx

Both these web services call should return back with list of web methods available. This will ensure that your TFS is working on the core areas.

When you try to connect to TFS from VS 2008 after the initial setup, you may get the error message

TF31002: Unable to connect to this Team Foundation Server.

 To fix the issue, check the Project Security settings on TFS Server. You need to ensure the domain account/local account that you are using to sign to your workstation has authorization on the TFS Server.

Once you grant permissions, the access error will be fixed.

When you try to create a new migration profile in MOSS 2007 which connects to MCMS 2002, you may get a sql connection issue.

This is due to the fact that SQL Server 2000 was not set to Mixed Mode. If it uses windows authentication mode only, the migration assistant in MOSS 2007 will not be able to connect to the data source.

To change to Mixed mode, right click on the server name in SQL Enterprise Manager –> Properties and change to Mixed mode.
