Hi,
Working with the OleDbConnection object is similar to using the SqlConnection object. However, because the OleDb.NET data provider can be used to connect to several types of databases, you must specify a provider name in the connection string. These provider names will be the same ones that were used with earlier versions of ADO. Here is an example of a connection string for a Microsoft Access database:

Hi,
The first function to be called in any C# program is Main. The CLR calls Main() when your program starts. Main() is the entry point for your program, and every C# program must have a Main() method.
It is technically possible to have multiple methods in C#; in that case you use the /main command-line switch to tell C# which class contains the Main() method that should serve as the entry point to trhe program.

hi,
Programming the Save button involves saving multiple records at the same time. The data saved
over a period of time accumulates and results in a large database. While databases can efficiently hold large amounts of information that can be queried, all that data is useless if the data is incorrect. Databases provide many techniques for ensuring the integrity and consistency of the database. Primary key and unique constraints...Leave a comment:

Hi,
A class library is a collection of classes that are compiled into a .dll file. By converting classes into components we need not copy the source code into the projects where we need to use the components. We need to just import the component into a new project. By using components, we can reduce the size of the exe files. This is because components are precompiled and do not add up to the executable file. For those developing...Last edited by Frinavale; Apr 27 '07, 01:25 PM. Reason: emoving link to website advertising as this is considered spamLeave a comment:
