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'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")

i need to read a sql table and insert all the records into another sql table in the same schema. It sounds dead simple but I've spent weeks trying different methods with no success.I'm using a datareader on the source table and a dataset on the target table. The program errors on the second iteration of the loop saying "@FunderAgreementNo" has already been declared. This is because I have the Parameter mappings contained in the loop (I think). I've tried moving this code elsewhere but then get different errors.

I have a simple form where when I set some data to the textboxes and I press a GO button, the code should execute a function called InsertCar() that takes all these values and insert them into the database and then return true if the transaction is done successfully or false otherwise. My problem is that nothing is being inserted into the table.

I searched internet including this forums to find a working example about the following subject but couldn't find a solution about my problem.I have two main problems:1) I have a DataGridView filled from the MySQL database table. I want code update the changed records, when a "Save Changes" button pressed by the user.I created the code below to make it. It makes update on the changed row, but enters Null values. So after the update on the database, the values become null.2) At "Private Sub cihazmodeli_SelectedIndexChanged" section my code reads the database and loads the values to the DataGridView. When I make another change on the Combobox, it adds the values of the new SQL results at the bottom of the previous records. I tried to clean the results using either Clear() or some other methods but got a message meaning "Content entered with DataSource can not be cleaned with Clear or other methods". What is the way of clearing the previous choice's records?

I'm using VB.net to write a MYSQL application and one feature I need to add is the ability to add a column for each week that my employees worked. For example I want the first column to be called "W1" and the next one to be "W2" and so on, right up to "W52". How would I add a column to my table and have it's name add 1 to its current value? If there wasn't any letters in the name it would be easy but I need it to have the "W" in the title as well to avoid confusion. to add the column I have this:
Alter Table Manager ADD W1 MediumINT;
I just need the part that adds an INTEGER to a VARCHAR datatype if possible... Maybe there should be some sort of data type conversion involved? Just to explain further, the black bar at the very top are the date stamps for each week, I would like to have this included in the datagridview if possible but it is not required. Under each week column the employees will be entering the percents they worked (example: 20%, or 0.20 is one day of work) I know this is an odd way of doing things but its mandatory... and i was wondering if it were possible to automate the creation of these columns rather than me having to manually enter them.
