I have a simple question.
With an interface I can force the classes that implements it, to implement methods and properties defined in the interface. But am I able to force the classes to inherit som other class, with an interface?
What you could do is make the class "inherit" the interface and then you inherit the class. If it is an abstract class I would imagine (because I've not tried it) that you could delay the implementation of the interface until it got to the class that inherits the abstract class.
Using an interface, you can only "force" a class to inherit only other interfaces.
If you want to force a class to inherit some other class, you can create, as others have said, an abstract class thats derives from the class you want to force inheritance. Keep in mind, though, that in c#, unlike interfaces, a class cannot directly inherit from multiple classe.
Without knowing anything other then your method names, did you include your access database file with your project? Did you hardcode the path to your access file, if so is that path still valid under vista?
I am using Mysql as my database.
i insert the date in the format DateTime.Now.ToString("dd/MM/yyyy") but the strange thing is its gets entered in dd-MM-yyyy format.
EVen if i manaually entered the date in database in dd/MM/yyyy and retrive the value from database , its get the format as dd-MM-yyyy.
where is the prob???
There is no problem. Databases don't store the date in a specific format - Don't know about MySql, but SQL Server and Sybase store it as a number, its up to your code to display it how you want. There will be a default format from the database (usually defined at server level) and its up to you to format it how you want.

Well, you could create a BItmap from test2.jpg, and assign it to a picture box ?
