well without knowing more details on your table structure and code this is kind of a vague question.

Basically you are just going to issue sql statements to return a set of customers

SELECT * FROM CUSTOMERS WHERE NAME LIKE 'Jo%'

would return customers name John Joe etc

you would then bind the result set to a grid etc and allow the user to select the customer they want, then you would instantiate a form for that customer ...

I'm ok with the SQL statement, i just want the VB.net source code, uhhmm.. i just cant figure out how the code is, just like a basic searching query.... like a text box... and a button , when i fill in the customerID in the text box, after i click on button , the result will return.

is an example of a quick search (can return multiple records) but I would take a look at the datagrid example for displaying your results.
