VB compile error when trying to use String.Compare - vb.net

Question

I am trying to check if the password is the same or not (in terms of caps too) using vb.net. But the line
result = String.Compare(actPassword,userPassword)
keep giving error "Compile Error: Expected:("
Private Sub Login_Click()
'Check to see if data is entered into the UserName combo box
If IsNull(Me.cmbLoginID) Or Me.cmbLoginID = "" Then
MsgBox "You must enter a User Name.", vbOKOnly, "Required Data"
Me.cmbLoginID.SetFocus
Exit Sub
End If
'Check to see if data is entered into the password box
If IsNull(Me.txtPW) Or Me.txtPW = "" Then
MsgBox "You must enter a Password.", vbOKOnly, "Required Data"
Me.txtPW.SetFocus
Exit Sub
End If
'Check value of password in tblEmployees to see if this matches value chosen in combo box
Dim userPassword As String
Dim actPassword As String
Dim result As Integer
userPassword = txtPW.Text
actPassword = DLookup("EmpPassword", "Employee", "EmployeeID='" + Me.cmbLoginID.Value + "'")
result = String.Compare(actPassword,userPassword)
If result = -1 Then
'Close logon form and open splash screen
DoCmd.Close acForm, "Login", acSaveNo
DoCmd.OpenForm "HomePage"
Else
MsgBox "Password Invalid. Please Try Again", vbCritical + vbOKOnly, "Invalid Entry!"
Me.txtPW.SetFocus
End If
'If User Enters incorrect password 3 times database will shutdown
intLogonAttempts = intLogonAttempts + 1
If intLogonAttempts > 3 Then
MsgBox "You do not have access to this database. Please contact your system administrator.", vbCritical, "Restricted Access!"
Application.Quit
End If
End Sub

Answer 1

That's because there is no String.Compare() in VBA (There is in VB.NET)
Also, please note VB.NET is not VBA
Use StrComp

Answer 2

Use StrComp
result = StrComp(actPassword, userPassword, vbTextCompare)

Answer 3

While String.Compare() exists in VB.Net, I don't think it does in VBA. In any case, what you're doing is wrong anyway.
String.Compare can return any integer and it will only return zero if they match. Your particular test (comparing against -1) is only checking one possibility, that the actual password is less than the desired one, and it's only checking for one of the possible negative values.
You would be better off in that case with something like:
if result <> 0 Then
However, if you just want to compare two strings for equality in VBA (rather than figure out the relative ordering), you can just use:
if actPassword = userPassword Then
