My combobox has 6 Categories with different data in the textfield's(12) correspond to the combobox...: here the pic:

http://img175.imageshack.us/img175/2254/pic1kt2.th.png

i'll be able to view data for cats.. but cant select the other 5 categories... is there something wrong with my coding??

Upzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz

In order for me to select the DATA's in the Table... i have to make a new connection, how am i suppose to select the data without making a connection to the database.... read.. its not make.. its select the data in table

then how am i suppose to make the combobox and the select database to work together?? cause i have like 6 categories with different data to enter and select corresponding to the combobox selected...

one more thing... u know anything about adding Count(id).. wanna make it count 1,2,3,4,5,6,7... cause my database now its 1-6 then repeats 1-6.... and remember.. i've done this programming a long time..... there's problems here and there and i need help correcting it......

well.. its something like this:
For Id increment when adding new data.. without duplicating...:

Code:

Private Sub count()
        Dim sqlConn As SqlConnection
        sqlConn = New SqlConnection("Data Source=localhost;Initial Catalog=Common;Integrated Security=true")
        sqlConn.Open()
        Dim cmd5 As SqlCommand = sqlConn.CreateCommand
        cmd5.CommandText = "Select count(id) from Common"
        f = cmd5.ExecuteScalar
        sqlConn.Close()
    End Sub
