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 ?

i have a excel document saved with temp.xls name.
i wanted to open this xls file as a new xls doucment,
not with the name temp.xls doc, and if we close the doc,
then documnent should ask the user to save file else
give me suggestion to solve this problem.
thanks in advance.
Your question is very hard to understand. You want to have a file called temp.xls, but don't want to open it as such? Create a copy of it and open it. If you don't want it to be overwritten, make it read-only.
tnanks for reply, actuly i saved an excel file into temp folder,
and if we open this file and then close it from upper left corner 'X'(close) button then excel document do not ask to save
the file, untill i don't do any modification in file.
so what i want, if i launch temp
file and then user try to close the file then document should ask
the user to save the file, if user want to save the file then it should ask for the filepath where he want to save, instead of using temp file path, beacuse i am using it for temprary purpose.
