I have a query from within my vb.net code which searchs for a record by date. The date being entered via the code is in format dd/mm/yyyy, i need to search in the database using yyyy/mm/dd? Ideally i thought there may just be a function within MySQL which will convert this. If not in vb.net to convert the string 01/01/2011 to 2011/01/01?

I am a bit of a newbie when it comes to vb.net and databases and I have a small favor to ask anyone I am looking for a very basic example on how to connect, read, update and insert data into remote mysql database. I have successfully connected to my database with the code below,, and for the moment I am just trying to LIST data from it in a listview control,, and then would like to find a way to insert data into it and update data.
Al examples I find on the net are too long and usually have too many unnecessary data around the code I need so I get a bit lost in it.Can anyone point me in the direction of SIMPLE examples that are easy to follow or provide a bit of useful code I could learn form.

I looked everywhere online and I couldn't locate an equivalent VB2008 code for this php code.
$field = mysql_fetch_assoc($result);
$field_title=$field["title"];
I'm trying to read the content of a field in a mysql database. I found this code below that does it but you must select the position of the field (column 0, 1, 2 etc) myData.GetString(1) instead of the name of the field. In the php code above it is "title". I'm looking for a command like myData.GetString("title")
Dim myCommand As New MySqlCommand
Dim myAdapter As New MySqlDataAdapter
Dim myData As MySqlDataReader

I have been disturbed for a week now. I have a project in vb.net. And on forms I have two masked text boxes. One is for the user to enter their date of birth and in the second one Iam trying to get the date the record is created. With this one I get the current date from pc and format it to dd/mm/yyyy because I want the user to understand the date. How do I INSERT the user date of birth and the the Now () date which is also in masked text box into a MYSQL database? I know how to insert other text but the date fails to appear in database.

I'm having a problem with a MySQL query for returning the "last visit" field in a table.Originally I had:select fname, lname, last_visit from patient where isactive = 1 and uid = 1Which worked perfectly in MySQL, but as soon as the query is executed by my ASP.NET app, it adds in the time field also to the date area. So 2011-12-12 becomes 12/12/2011 12:00:00 AMI tried this also, with no improvement:
