In WCF, while using one way contract, suppose a client invokes a method and the server while executing it, encounters an error. Will the error message propagate to the client or will the client ever know that there was an error on the server side ?

  
No, one-way operations cannot return values and any exception thrown on the service side will not make its way to the client. The client will never know whether there was an error or not ! (More...)

What is service and client in perspective of data communication?

  
A service is a unit of functionality exposed to the world.

The client of a service is merely the party consuming the service. (More...)

How to set the timeout property for the WCF Service client call?

  
The timeout property can be set for the WCF Service client call using binding tag.

binding = "wsHttpBinding"
bindingConfiguration = "LongTimeout"
/>






If no timeout has been specified, the default is considered as 1 minute.

If you have a Dotnet Web Service and a Java Client Application, then which Communication technology will you use other than WCF ?

  
Web Service (that is), ASMX will be the most likely way to achieve cross-vender inter-operability. (More...)

What is a view?

  
If we have several tables in a db and we want to view only specific columns from specific tables we can go for views. It would also suffice the needs of security some times allowing specfic users to see only specific columns based on the permission that we can configure on the view. Views also reduce the effort that is required for writing queries to access specific columns every time. (More...)

What is a view? How it is related to data independence?

  
A view may be thought of as a virtual table, that is, a table that does not really exist in its own right but is instead derived from one or more underlying base table. In other words, there is no stored file that direct represents the view instead a definition of view is stored in data dictionary.

Growth and restructuring of base tables is not reflected in views. Thus the view can insulate users from the effects of restructuring and growth in the database. Hence accounts for logical data independence. (More...)

What is VDL (View Definition Language)?

  
It specifies user views and their mappings to the conceptual schema. (More...)

Where is window Service Entries located in the system

  
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services (More...)

Session state vs View state

  
In some cases, using view state is not feasible. The alternative for view state is session state. Session state is employed under the following situations:
. Large amounts of data - View state tends to increase the size of both the HTML page sent to the browser and the size of form posted back. Hence session state is used.
. Secure data - Though the view state data is encoded and may be encrypted, it is better and secure if no sensitive data is sent to the client. Thus, session state is a more secure option.
. Problems in serializing of objects into view state - View state is efficient for a small set of data. Other types like DataSet are slower and can generate a very large view state (More...)
