Ok, Iv'e got my macro code for a login form and will post it shortly. The whole idea for the login for is to be able to type in a username and password and will dispaly a confirmation message which lets the user know they have successfully logged in. The user will then be automatically directed to the main menu part of my system. I have successfully got the login for to display an error message when the user doesnt type in a username or password but I cannot get the system to log the user in if they enter a username and password. Could someone please look at my code below and give me an idea were ive went wrong? thank you :)
-------------------------------------------------------------------------- Sub LogIn() 'stops the screen from flickering Application.ScreenUpdating = False 'declares variables Dim uname As String Dim pword As String Dim RowNum As Integer Dim usercount As Integer Dim rowcount As Integer 'moves worksheet and sets values to variables Sheets("LogInForm").Select uname = Range("Username") pword = Range("Password") RowNum = Range("NumUsers") 'if values are not empty If uname < "" And pword < "" Then 'set variables as values to move through rows usercount = 1 rowcount = 1 'move sheets Sheets("UserDetails").Select ' Do While usercount <= RowNum 'if correct uname and pword are correct values If uname = Range("A" & rowcount) And pword = Range("B" & rowcount) Then 'move worksheets and reset values , then moves sheets Sheets("LogInForm").Select Range("Username") = "" Range("Password") = "" Sheets("MainMenu").Select Exit Sub 'if values dont match Else Error = True usercount = usercount + 1 rowcount = rowcount + 1 'ends if statement End If 'starts loop Loop 'if the boolean is true If Error = True Then 'moves sheets, clears form, displays message box Sheets("LoginForm").Select Range("Username") = "" Range("Password") = "" MsgBox "Please try again, You must enter a valid username and password", vbOKOnly 'ends if statement End If 'if the boolean is false then display error message Else 'displays message box MsgBox "You must enter both a username and password" 'ends if statement End If End Sub |

Take a look at this code and see if it suits your purpose. There are a few other things I'd fix in there to make it more efficient/tidy, however it works and meets the requirements of your assignment. Let me know how you get on. Code:
Sub LogIn() 'stops the screen from flickering Application.ScreenUpdating = False 'declares variables Dim uname As String Dim pword As String Dim PasswordFound As Boolean 'moves worksheet and sets values to variables Sheets("LogInForm").Select uname = Range("Username") pword = Range("Password") 'if both values are not empty then check to see if they are a valid combination If uname < "" And pword < "" Then ' Move to the sheet of username/password combos Sheets("UserDetails").Select Range("A1").Activate PasswordFound = False ' Keep reading until the bottom of the list of usernames Do Until ActiveCell = "" ' do the username and password match? If ActiveCell = uname And ActiveCell.Offset(0, 1) = pword Then PasswordFound = True ' move down to the next row ActiveCell.Offset(1, 0).Activate Loop 'if correct uname and pword are correct values If PasswordFound Then 'move worksheets and reset values , then moves sheets Sheets("LogInForm").Select Range("Username") = "" Range("Password") = "" Sheets("MainMenu").Select MsgBox "Your login was successful", vbOKOnly, "Login Success" 'if values dont match Else MsgBox "Please try again, You must enter a valid username and password", vbOKOnly, "Login Unsuccessful" 'ends if statement End If 'if the boolean is true If ErrorX = True Then 'moves sheets, clears form, displays message box Sheets("LoginForm").Select Range("Username") = "" Range("Password") = "" 'ends if statement End If ' Both password and username not entered Else 'displays error MsgBox "You must enter both a username and password", vbOKOnly, "Username and Password Required" 'ends if statement End If End Sub |
