Modules & VBA :: Validate Username And Password In A Button?
Jan 20, 2014
I would like to ask how can i validate the username and password in a textbox? I have a frmLogin and frmMain.
I have also a table called 'tblUsers' with column fields 'username and password'.
If username is not found in database then a msgbox will prompt 'Username is not yet created'.
If username is okay and password is incorrect then msgbox will prompt 'Incorrect password'
If username and password is okay, then a msgbox will prompt 'Successfully login' and will continue to frmMain.

Being dealing with my database and having quite some trouble with it. Is it possible to track down what the users did, during the time they login into, database, is it possible to prompt users for password and username when they buttons for like, delete cmd, or update command.
Just a breif idea on what im trying to do.(hopefully it won't confused you all)
Im trying to created a 2 main username. One is for admin group and another is for users group. Then users can login in to database, however whenever the users update or delete entries in the database, the user will prompt for their username and password (not the users group login ). Is it possible to build a table to store in the username and password for the prompting purposes one.
Sorry for confusing question. Actually im trying to think of another way, but for now this complicated event all i have think of. Feel free to voice your suggestion here. Thanks alot. TQ

I'm new to access vba and I'm trying to create a login form. I have already my code to login but i want to validate the password in 'case sensitive' basis. Below is only what I've got so far.
Code:
Private Sub cmdLogin_Click() Dim login_validation As Variant login_validation = DLookup("Password", "tblLogin", "Username='" & Nz(txtUsername.Value, "") & "'") If Nz(login_validation, "") <> Nz([txtPassword].Value, "") Then MsgBox "Incorrect Password. Please try again." txtUsername.Value = "" txtPassword.Value = "" txtUsername.SetFocus Else MsgBox "Hi " & txtUsername.Value & "," & vbNewLine & vbNewLine & "you have successfully login!" DoCmd.OpenForm "frmMain" End If End Sub

I created a password for my database and now I cannot access it. The dialog box says that either the username or password may be incorrect. I do not know what the requested username is. I do not recall creating a username during the process of creating the password. I do not know what username ACCESS is asking for. I think I know what the password is. I think the problem is the username. However, if I somehow do not know the password, what can I do?
After you finish laughing at me, please help. Thanks for any assistance you can provide.

Access 2007 / I'm creating a database form that has a combo box drop down pulling EmployeeName and a free text field to enter a password. I need the password entry validated against the password stored in a column on the same row as the Employee Name selected from the combo box when a button is clicked. . IF, that value is validated, I need the button click to also record a "time in" or "clock in" entry in a different table.how to validate the password.

Hello!
I have a problem regarding using usernames and passwords to restrict access to certain tables/forms/reports etc....
I have read around the forum and various other websites but cant seem to get much relating to exactly what i am wanting to do.
I think i understand the way the access workgroup security works. But does this not just restrict users being able to view the database as read-only or with other certain rights like that? So, firstly would i be able to use this to restrict the database the way i want?
Or is there a way to create a table with names and passwords and create a form at the beginning where the user inputs their details and then according to the details gives/restricts access to parts of the database? Ideally i'd like the startup form to direct them to a different menu according to the user which gives them only the options they are allowed?
Seems a bit of a mouthfull and i sound like a complete newb but i been trying to figure this out all day!!
Thanks

I created security using the security wizards, separating admins vs. data entry users. I gave everyone a username and a password but when I reenter the database it doesn't ask me for my username or password. Does anyone know why or how can I fix it?

Hello,
I was wondering if it were possible to make a msg box pop up when opening a database asking for a user name and password. And that will be the only way to enter the database.
Thanks

Hi Freinds,
After viewing all the threads i got some useful information but just wanted some help as i am not a programmer but can understand logics. There are 2 issues i want to resolve
1. First query is i have a login form and in a table there is username password. Now issue is based on the username person should be able to view things. There would be 6 differrent departments. So i would have six users and 1 id only for viewing. These six users should be able to see there own records either assigned to them or create new query and assign to any other 5 users. Now option is either I create six replicated forms and based on the user login i open user form or switch board. Can there be any option where in a table i store the activities they can do and whereever these guys go the code check in table and enable or disable the view of items for other guys. Users would be accessing forms, reports and they would have option of entering cusotmer information and querying and changing information. The user which has option of viewing reports will only have option of seeing some customized reports.
2. Second query is that these six users would be addressing issues to each other regarding cusotmer issue. In this every response of the case should be stored in a table. i.e. like for customer x user1 said abc on 10th then user2 said cbf on 11th. so this would have history of case what was happeining in the matter.
I dont know how to go about this and if there is a easy solution. I dont want to use access security cause then all the six users would have security file.
Would apreciate your help and till now whatever responses i have seen in other forms they were quite helpful and did help me lot in understanding access.
Thanks to all who would be visiting this thread and taking pain in answering the query.
Take care
Ankur

I am trying to validate that the user selects at least one checkbox out of three on the form in Access 2010. They can select one, two or even all three if they wish, but at least one must be checked. I am using the following code attached to the click event of a command button. It was fine but seems to have stopped working. The control names are generic to illustrate my code. The form is unbound:
if (chk1 + chk2 + chk3) = 0 then
Msgbox "Please select at least one checkbox"
exit sub
end if

I have a textbox where I need an afterupdate event, which should check that input is 3 letters followed by 3 numbers. The total is 6 characters, but always 3 letters + 3 numbers. If condition not met, a msgbox will be shown, for the user to input correctly, before being able to continue.

I have a table called 'Klanten' which contains the rows 'password' and 'login' (and several rows not needed for this form)
So I'm trying to make a login form which first checks if something is entered (this part of the code seems to work).
Private Sub Knop13_Click()
'Check to see if data is entered into Username
If IsNull(Me.Username) Or Me.Username = "" Then
MsgBox "gelieve een login in te voeren.", vbOKOnly, "Required Data"
Me.Username.SetFocus
[Code] ....
But from then on i seem to have some issues.. The part of the code underneath seems to only work for the first 'login' and 'paswoord' in my table called "Klanten".
-Username is the name for the field where they enter their 'login'.
-Password is the name for the field where they enter their 'paswoord'
If Username.Value <> DLookup("[login]", "Klanten", "[Username]='" & Username & "'") Then
MsgBox "Invalid Username. Please try again.", vbOKOnly, "Invalid Entry!"
Exit Sub
End If
If Password.Value <> DLookup("[wachtwoord]", "Klanten", "[Password]='" & Password & "'") Then
MsgBox "Invalid Password. Please try again.", vbOKOnly, "Invalid Entry!"
Exit Sub
End If
Then as last part i would like to goto another form called 'Mainmenu' if both the Login and the Paswoord is correctly entered in the fields Username and Password. Here i have the most issues as this doesn't seem to do anything at the moment
If Password.Value = DLookup("[wachtwoord]", "Klanten", "[Username]='" & Username & "'") And Username.Value <> DLookup("[login]", "Klanten", "[Password]='" & Password & "'") Then DoCmd.OpenForm "Mainmenu"
End Sub

I am having an issue using DCount to validate against 3 fields within my database. I have a booking form which contains a Staff member, viewing slot, and Viewing Date which is used to book property viewings.
I want the form to check that the booking doesn't already exist when the process booking button is pressed.
I am using the following statement:
Code:
If DCount("*", "Viewing", "[Staff_ID]=" & Me.[Staff_ID] & " AND [Viewing_Period] = " & Me.Viewing_Period & "' AND Viewing_Date = '" & Me.Viewing_Date) & "'" > 0 Then
MsgBox "Cannot book, booking already exists", vbCritical
End If
I always get the error "Syntax Error (Missing Operator)".

I'm trying to find a code that will allow me to check a value of a yes/no checkbox based on a username.
What I want to happpen is:
1. The code looks to see if the username that is entered in "txtUsername" field on the form matches the "empUsername" value on the table "tblUsers."
2. If there is a match, I want it to look at the value for the field "Admin" on "tblUsers" to see if the value is checked as true.
3. If the value is true, I want it to open a specific form "frmAdmin." If it is false, I want it to open a form "frmMain."
VBA codes not recognizing the Admin field and instead taking all users into the frmMain.
