i am able to save data into the database but when i press save button it shows errors but the data i wont save is going to the database...............i am a bit confused plz help!.....i am using Vb 6.0 ans Ms access 2007
i am highlighting statements where errors occur.....

first: you should use rs.edit before rs.update and rs.save after rs.addnew. you are using rs.Addnew and rs.Update after each other.
second:
rs1.Open "SELECT * FROM Sales where Book_id=' " & cboBid.Text & " '", con, adOpenDynamic, adLockPessimistic
you might want to consider converting the cboBid.Text to a number using CLng() and you should use the single quote for numbers.
rs1.Open "SELECT * FROM Sales where Book_id= " & CLng(cboBid.Text), con, adOpenDynamic, adLockPessimistic
HTH:D

ALSO - do NOT use .TEXT - Get rid of them all in that code. Just use the .Value and you don't need to put .Value because it is the default.

So this:

rs("Book_id") = cboBid.Text
rs("Bookname") = txtBookname.Text
rs("Discount") = txtDis.Text
rs("Sellingprice") = txtSp.Text
rs("Quantity") = txtQuantity.Text

Needs to be this:

rs("Book_id") = cboBid
rs("Bookname") = txtBookname
rs("Discount") = txtDis
rs("Sellingprice") = txtSp
rs("Quantity") = txtQuantity

The use of .Text requires the control to have the focus where using the value does not. There are very few places where you need to use .Text.

Oh, I just noticed you said you are using VB6 FE and Access BE. Ignore what I said then. Also you posted this in the wrong category. I'm moving it to the VB category.

Thank u Sir!.....Thank u very much!........
