We are on Microsoft SQL Server and not MySQL.

Maybe you can get better help here: http://www.dbforums.com/mysql/

ok..but do you know what record you need to update against? firing an open update query results in all rows of table getting updated

I think:

where username = 'txtupdate.text'

will cover that Visakh - although the syntax looks wrong, I think it should be:

'cmd = New MySqlCommand("Update user_account set (username,pass,sign_as) values('" + txtcreate_username.Text + "', '" + txtcreate_pass.Text + "','" + cmb_reg.Text + "')where username = '" + txtupdate.text + "'", conn)

I'm presuming this syntax is OK in MySQL?


UPDATE MyTable
SET (Col1, Col2, Col3) VALUES ('Value1','Value2','Value3')
WHERE ...

??
More normally the syntax is


UPDATE MyTable
SET Col1 = 'Value1',
    Col2 = 'Value2',
    Col3 = 'Value3'
WHERE ...
