Strange wait types

Posted By:      Posted Date: September 22, 2010    Points: 0   Category :Sql Server


I get some unexpected wait types on a test server. Most of them seems to be of type “ignore, it’s usually not a problem”. See: http://blogs.msdn.com/b/psssql/archive/2009/11/03/the-sql-server-wait-type-repository.aspx

From Perfmon I get catastrophically bad I/O figures:

Avg. sec/Disk Read = avg. 0,150-0,200 secs, max 3-4 secs
Avg. sec/Disk Write = avg. 0,150-0,200 secs, max 3-4 secs
(I usually target 0,015 as an acceptable value for both values)

MOSS 2007 Strange Problem with edit forms, content types and document library columns


I'm having a strange problem and have not been able to track down any useful answers over google.

I inherited a SharePoint site that I am now making some changes to.

I am having problems with one document library.  We had custom edit forms on this document library, which I was finding a pain to maintain so I reset them back to the site definition.  This edit form now shows only those fields that are associated with the Document content type (the only content type - I've deleted the others) on the document library.  There are other columns on this document library that are NOT associated with the content type that I would like to show on the edit form but they are not available when I try to add them to the content type via Settings > Document Content Type > Add from existing site or list columns.  The select columns from drop down is set to List Columns.  The Additional Authors column is just not there.

I CAN see this field on the all items view for the document library, it is there and populated with data.

Setting the Allow Managed content types radio button to NO does not have any impact on which fields are visible on the form- I still see those same fields that have been associated with the Document content type.

Has anyone else seen this or does anyone have any thoughts??

SharePoint Tutorial - Content Types

SharePoint content types provide users with a way to manage and organize content in a more meaningful way. It's a reusable of settings you want to apply to a particular type of document in a library or item in a list.

UML Diagram Types

UML provides a number of diagram types as a mechanism for entering model elements into the model and showing overlapping sets of models elements and their relationships. UML does not specify what diagrams should be created or what they should contain, only what they can contain and the rules for connecting the elements. The diagram types include:

UML Diagram Types - 2

Further diagram types include:

Activity Diagrams - a generic flow chart used much in business modelling and sometimes in use case modelling to indicate the overall flow of the use case. This diagram type replaces the need for dataflow diagrams but is not a main diagram type for the purposes of analysis and design.

Ready made List Types provided by SharePoint

SharePoint provides some out of the box List Types. Some of the most used ready made list types that SharePoint provides currently are listed below:

Tuples, Anonymous Types, and Concrete Types

Tuples can save you a great deal of repetitive tasks. They can also lead to completely unreadable code in a language like C#. Tuples are data values that contain N items. The .NET framework supports tuples containing 1 to 8 members. To use tuples with more than 8 members, you use another tuple for the member of an octtuple

Content Types in MOSS 2007

In this article I will try to describe the one of the best feature in Microsoft office Share Point 2007 called Content Types.

Content types are simply collection of contents.Each content in a Content type can have different settings.Basically it is a reusable collection of settings which you want to apply to a particular category of contents.

Data Types - Date and Time in SqlServer

Date and time values can be stored with either the DATETIME or SMALLDATETIME data type. The difference between the two is that SMALLDATETIME supports a smaller range of dates and does not give the same level of precision when accounting for time. The DATETIME data type can hold values from January 1st of 1753 to December 31st of 9999. The time is stored to the 1 three hundredths of a second and each value takes up 8 bytes of storage. The SMALLDATETIME data type can hold values between January 1st 1900 and June 6th of 2079. The time is tracked to the minute and each value takes up 4 bytes of storage. The majority of business applications can live happily with SMALLDATETIME, however, if you are in an environment where each second matters or you need to make estimates to the distant future (or past) then you have to resort to DATETIME. If you fail to specify the time when inserting a value into a DATETIME or SMALLDATETIME column, a default of midnight is used. If you fail to specify the date portion the default of January 1, 1900 is used.

How do I persist custom complex types in design-time


Let's say that I've got one custom webcontrol called MyControl.

public partial class MyControl: WebControl {
public IComplex Complex { get; set; }

The control is a very simple control but it holds an instance of a complex type that is accessable through a property. The property has the propertytype IComplex

public interface IComplex {
string Name { get; set; }
List<IComplex> Children {get;}

Let's say that I am able to pick one of several different types of object that derives from IComplex in design-time and assign it to the controls property "Complex" property.

Naturally I would like to persist this information to the HTML-View in a user-friendly way.

Because we don't know what type the user has picked there is no way to instansiate the type if we don't persist the name of that type. The Type could also contain more properties than the Interface the controls property is refering.

<cc1:MyControl id="MyControl1" runat="server">
<Complex> <!-

Pure C++: Reflecting on Generic Types


A funny thing happened to templates on their way to the common language runtime (CLR)-they lost their {type} identity. This is analogous to what happens with macros under native programs. Just as the C/C++ compilers have no awareness of macro preprocessor expansions, the CLR has no awareness of template instantiations.
