Logins by different users

Dear all,

I am trying to create a login for different users to have access to certain forms in vb6 I have an oracle database which has three different tables for three different user each have a username and password.

the code that is working for one user is below


If rs.EOF <> True Then

If rs!password = Text2.Text Then

Pass = Text2.Text


Unload Me

form1.Show
else
msg


the rs is the select query selecting the username and password from one table where its the username = text1

Hope some1 can help?

you only query the same record for all users, you would need to loop through the record set to find if that password matched the user name in any record

I am new to V so how would I loop through the differents tables?

it looks to me that you are using ADO and i am just changing to that now, so this may not be right

VB Code:

rs.movefirst
 do while not rs.eof
 
       if rs!user = textuser.text then exit do
       rs.movenext
 
loop
 
if rs!pass = textpass.text then 
' login good
else 'login bad
end if

this isn't quite right because if it gets to the last record with out matching user it will still look for a password

we can put the processing logic inside the rs loop itself..;)

dim passfound as boolean
passfound=false
rs.movefirst

do while not rs.eof
if rs!user = textuser.text then
if rs!pass = textpass.text then
' login good
passfound =true
else 'login bad exit do
end if
rs.movenext
loop

if passfound=false
msgbox "enter correct passwd"
else
<ur processing here>
endif


thnx

doing loop is not an option if u have many user

try this

VB Code:

sSQL = SELECT UserPassword FROM tblUser WHERE Username = '" & txtusername.text & "' AND UserPassword = '" & txtPassword.text & "'"
rs.open sSQL, ur_conn, adopenForwardOnly, adLockReadonly
if rs.eof = true and rs.bof =true then
  msgbox "Not Found"
else
  'do ur stuff here
endif

the method above is prone to SQL injection..so u might want consider using SP or PQ to do it

hmm maybe u required Level field at user Table? so if level user is '1' or '2' then u can make it 'direct' to certain form

hope it can help

:ehh: :confused:

Erick, may be I can't comprehend but he wrote "three different tables for three different users" while your query assumes there to be a single table tblUser.
