The field in my access database is of type date, but I don't know how to add a date using VB.net and oledb,

Help Arrived

Treat the date as a normal string, except that you have to make sure the date conforms to the particular date-format of the field, eg short date 01/12/2004.
Furthermore, the you have to place the date between hashes, like this "#01/12/2004#'.

Maybe if you give a more detailed description of how you want to use the date, I could be of more assistance, since there are various date functions. (And of course different implementations for different situations).

My Code

This is my code, I have a simple application where I can store events of appoinments that i need to remember. I'm trying to make a planner or diary but it's not going to be very complexe.

All it does is store a title, date and details about the appointment. The problem is when I need to add the date to the database.

It is an Access database, the date field is a type called short date.

VB.NET:

DO it the EZ way

Probably the most effective way would be to place a date-time picker on the form. Use the string-value of the date time picker for the @date parameter. If it kicks you out just place it between "#"`es (hashes).

(Sorry I don't have my code with me right now, but I reckon it's straightforward enough)
