Modules & VBA :: Validate Password Case Sensitive
Jan 20, 2014
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 found a useful password protected form using input box and tried it successfully. However there are two issues. The password is not case sensitive and the password entered displays in the box. Is it possible to turn the password to case sensitive and the entered password is displayed as *s.
'Attached to On Click event of cmdOpenEmpForm
Dim strPasswd
strPasswd = InputBox("Enter Password", "Restricted Form")
'Check to see if there is any entry made to input box, or if
'cancel button is pressed. If no entry made then exit sub.

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.

Is there any reason as to why, when searching a MDB file via ASP, that it would be case sensitive by default?

I am using the following:
SELECT CPL_CLIENTS.CODE, CPL_CLIENTS.FULLNAME FROM CPL_CLIENTS
WHERE (((CPL_CLIENTS.FULLNAME) Like "*" & Forms!frmSafeKeep_AddClient_SearchDesig!txtSearchT ext & "*"));
As the control source of a listbox, so that the user can enter something in "txtSearchText", and the listbox will be narrowed to only those those clients that have a matching part of their name.
The problem is that the user enters, for example, "duncan", and the list returns nothing, when in actual fact there are 5 matching records. If the user enters "Duncan" (note the capital letter), they get all 5 records as they should.
If memory serves, access should only be case sensitive if you tell it to be - and this is working fine on other forms.
The only difference between them is the data source. Other forms are getting data from linked tables in the backend. This form is getting it from a linked Oracle table.

I'm trying to open a report and highlight certain text. So I have a textbox that takes the original field and replaces certain text (based on user input) in bold red. Here is my formula:
Code:
=Replace([Language],[txtKeyword],"<font color = ""red""><b>" & Upper([txtKeyword]) & "</b></font>")
It works fine, but the only problem is, I don't know how to make it case sensitive. So let's say the user input (txtKeyword) is "contract." If it's the beginning of a sentence, I want the C to remain capitalized, but if the C is not capitalized, I don't want it to show capitalized. Is there a way to do this without making the formula really long?

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.

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)".

If InStr(1, Me.txt_sp, "give and take", 1) Then TM = "Standard"
If InStr(1, Me.txt_sp, "Give and", 1) Then TM = "Standard"
If InStr(1, Me.txt_sp, "priority working", 1) Then TM = "Standard"
If InStr(1, Me.txt_sp, "priority boards", 1) Then TM = "Standard"
If InStr(1, Me.txt_sp", 1) Then TM = "2 Way"

My problem now is about evaluating the result of that query in order to calculate quarterly and annual performances. The query returns correctly:
1) NULL - when I don't have values in the given month
2) 0 - when one of the components of the performance formula is 0
3) value (positive or negative) which can include any positive or negative value
In order to calculate the quarterly values I need the performance of the last month in the quarter and the first month in the quarter. My monthly values are stored in columns so say for Quarter 1, I would need something like this:
Code:
[mar]/[jan]-1
As you might have thought, the problems come when I have NULL or 0 values. Let me give you a couple of examples.
[jan] is NULL
[feb] is a value
[mar] is a value
Than my formula would have been
Code:
[mar]/[feb]-1
Second case:
[jan] is 0
[feb] is 0
[mar] is 0
In this case I would like the formula return '-' because I want to be able to spot the case in which the quarterly performance is 0 because the initial values were 0 from the case in which the performance was actually 0 (i.e., say [jan] = 101 and [mar] = 101 then performance is 0 which is different from having [jan] and [mar] = 0 thus performance '-').You can combine the three states (NULL, 0, value) with the three months and find many combinations (I have found 27 relevant ones).
I initially thought to use SWITCH in SQL to evaluate the 27 combinations but I found out that SWITCH would evaluate non more than 15 conditions. So I guess the solution should be use a function in VBA which does what I was about to do with SWITCH in SQL.
I have built a test function which evaluates the numerator of my formula using only two cases (CASE 1: all variables have a value <>0, and CASE 2: the first month is null, the second is 0 and the third a value). Here the code:
Code:
Function evaluate_s(Var1, Var2, Var3) As Double
Select Case Var1
Case Is <> 0
[code]....
My main question here is what is wrong in the syntax of my function. Why is not correctly evaluating at least the two cases in my function? I always get 0 for all records.

I want to know if it's possible to make a dynamic select case. In my form I have 3 separate combo boxes. What I want to happen is depending on what was selected in one the options in the other two change and if you select something in the second the option in the third narrows down again. The user can select these in any order. They can use one by itself or all three independently. In my code I can do this with many select statements, e.g
Select Case Me.combobox1.Value
Case "choice1"
Forms!CurrentForm!combobox2.RowSourceType = "Table/Query"
Forms!CurrentForm!combobox2.RowSource = "SELECT fieldname FROM tablename WHERE fieldname = '" & Me.combobox1.Value & "'"
End Select
In the place I have "choice" is it possible to write something along the lines of,Me.combobox1.value = "SQL Code"..The idea that this code would still work if the user adds more data to the tables which these combobox choices come from.

Can I look up and verify data on a "second" form based on a selected record from first (still open) form.
I am trying to allow users to select a User Name from a combo box list and then open "Change Password" form when they select "Change Password" for that selected user name.
My problem is that I can't figure out how to associate and verify the data tied to the user name selected on the previous (Login) form ( I am trying to validate the old password tied to that selected record).
I have the first login form created, and it's working just fine. I also have the change password form created (and it's displaying the user name selected from the first form using:
Code:
Private Sub Form_Load()
With Forms![frmLogin]![cboUserName]
Me.txtPwdChgUserID = .Column(2, .ListIndex)
End With
EndSub
I also have the code written to validate and confirm old password, new password and validate new password (when the save button is clicked). I have yet to update the password with the new password (still trying to figure that out).
Attached zip file has screen shots of the two forms.

I have a boolean array, foundState(3), whose 4 elements correspond to 4 variables describing conditions that will dictate what action is taken upon closing a form.
There are only 6 possible outcomes for the array, and they can be divided into just 4 cases:
Case {T,T,T,T}
Case {T,T,T,F} OR {T,T,F,F} OR {T,T,F,T}
Case {T,F,F,F}
Case {F,F,F,F}
What the proper syntax would be for this if I'm trying to create a "Select Case" statement for these 4 cases.

I have two queries called "Query_match_AND" and "Query_match_OR". I want to show the total number of records for either of these queries in a form called "form_candidates_result" depending upon the combo box value (either "AND" or "OR") in a form called "form_match".If I put
Code:
=DCount("*","Query_match_AND")
in the control source of [candidatecount] in "form_candidates_result", the value is shown in the form and it works fine.If I use the following code in either of the "on load" or "on open" events in "form_candidates_result"...
Code:
Select Case [Forms]![form_match]![ANDOR]
Case "AND"
Me.CandidateCount.ControlSource = DCount("*", "Query_matching_AND")
Case "OR"
Me.CandidateCount.ControlSource = DCount("*", "Query_matching_OR")
End Select
it doesn't work and I get

I have an issue with this case select below. The DelayStart is time so lets say I put in the debug window
?DatePart("h", #04:00pm#)
The result would be 16 which is correct BUT the issue is my second shift starts at 04:01pm and the result is still 16 untill 5pm. How do I fix this so I get the correct shifts? Im guesing use something other than DatePart but what?
'Daylight 6:00am - 4:00pm
'Afternoon 4:00pm - 2:00am
'Midnight 2:00am - 6:00am
Code:
Public Function getShiftForRecord(DelayStart As Variant)
On Error Resume Next
Select Case DatePart("h", DelayStart)
Case 6 To 16 'Daylight 6:00am - 4:00pm

I would like to select a case depending on the output of a function.
This function tests the syntax of the reporting month.
If the syntax is fine nothing should be done further in the main sub else it should return to the Input window for the reporting month.
Somehow it doesn't work out.
Code:
Public Function RepMonthCheck(rep_date As String) as Boolean
If Len(rep_date) <> 6 Or Left(rep_date, 2) > 12 Or Left(rep_date, 2) < 1 Then
MsgBox ("Reporting rep_date is not in the correct format = mmyyyy")
Return False
ElseIf Right(rep_date, 4) > 9998 Then
MsgBox ("No forecast available for year 9998")
