Hello it's me again i'm having problem with the database subtraction for my POS Project im using ado database and i know that you just have to change the value from the selected and voila it would update the database but mine doesnt work:


' txtqan is connect to the item database
txtqan.text = Val(txtqan.text) - Val(txtsalesqan.text)

So you are using the ADODC (ActiveX Data Objects Data Control) right???

adodc1.Recordset.Update

Good Luck

Try the following -

Dim x as Integer, y as Integer, z as Integer
x = Val(txtQan.Text)
y = Val(txtSalesQan.Text)
z = x - y

rsQan!Qauntity = z
rsQan.Update
'rsQan is your recordset
'Qauntity is your field name

Hope this solves your problem.
