How to load person from DB, read details (and maybe print to MsgBox), alter firstname and save back to db?

Hello,

i want to

- load a person form the DB

- read some details about the person out of the data and print it to MsgBox

- change the firstname of the person

- save the changed dataset back to the db

Could you provide example code for that?

I am using the Free Virtual Trial from https://www.oneidentity.com/register/64187/

So this is my data-base.

Thanks - Michael
