I have a select case to chose what is true. THe problem is if the information isn't in the database, it automatically skips to the else however i dont kno why.

I have a function that returns an errmessage once it is returned then i use the select case.

the code for the function is:

Function SQLCHECKUSER() As Object
        Dim query1 As String = "SELECT [User_Name] FROM [FDXUSER] WHERE ([User_Name] ='" & User_Name.Text & "')"
        Dim query2 As String = "SELECT [employee_number] FROM [FDXUSER] WHERE ([employee_number] ='" & empnumber.Text & "')"
        Dim query3 As String = "SELECT [Email] FROM [FDXUSER] WHERE ([Email] ='" & email_address.Text & "')"
        Dim sqlcommand As New OleDbCommand(query1, Sqlconnection)
        Dim sqlcommand2 As New OleDbCommand(query2, Sqlconnection)
        Dim sqlcommand3 As New OleDbCommand(query3, Sqlconnection)
        Dim obj As Object
        Dim obj2 As Object
        Dim obj3 As Object

        obj = sqlcommand.ExecuteScalar()
        obj2 = sqlcommand2.ExecuteScalar()
        obj3 = sqlcommand3.ExecuteScalar()
       
        If obj & obj2 & obj3 Is Nothing Then
            Return errmessage = "SUCCESS"
        Else
            If obj Is Nothing Then
                Return errmessage = "INSERT"
            Else
                Return errmessage = "USER"
            End If
            If obj2 Is Nothing Then
                Return errmessage = "INSERT"
            Else
                Return errmessage = "EMPLOYEE"
            End If
            If obj3 Is Nothing Then
                Return errmessage = "INSERT"
            Else
                Return errmessage = "EMAIL"
            End If

        End If

    End Function

Then the select case is:

SQLCHECKUSER()
                Select Case errmessage
                    Case errmessage = "EMPLOYEE"
                        pageerrorlbl.Text = "Sorry! The Employeed Number You have entered already exist. Please Contact the Web Admin if you think this is a mistake."
                        Exit Sub
                    Case errmessage = "USER"
                        pageerrorlbl.Text = "Sorry! The User Name You have entered already exist. Please Contact the Web Admin if you think this is a mistake."
                        Exit Sub
                    Case errmessage = "EMAIL"
                        pageerrorlbl.Text = "Sorry! The Email Address You have entered already exist. Please Contact the Web Admin if you think this is a mistake."
                        Exit Sub
                    Case errmessage = "INSERT" Or errmessage = "SUCCESS"
                        Sqlcommand.CommandText = sqlinsert
                        Sqlcommand.Connection = Sqlconnection
                        Sqlcommand.ExecuteNonQuery()
                        Response.Redirect("confirmreg.aspx")
                        Exit Select
                    Case errmessage = "FAILED"
                        pageerrorlbl.Text = "Sorry! Something is wrong. Please contact the administrator"
                        Exit Select
                    Case Else
                        pageerrorlbl.Text() = "SKIPPED EVERYTHING"
                        Exit Select
                End Select

for some reason it skips the entire select case command and goes straight for else.

I'm not familiar with ASP but in VB, and from what I've seen of ASP, your Case statements should not include
errmessage =
but should just be
Case "EMPLOYEE"
...
Case "USER"
...etc, etc...
- that's my hunch, anyway...

hmm... this didn't work either.

now i get

Conversion from string "INSt" to type 'Long' is not valid.

in the top left as catch exception

It seems that the error is not related to Select Case statement.

I have checked your code after removing 'errmessage = ' from your Select Case.. statements. It is working without throwing any error.

See this below code

Select Case errmessage
            Case "EMPLOYEE"
                pageerrorlbl.Text = "Sorry! The Employeed Number You have entered already exist. Please Contact the Web Admin if you think this is a mistake."
                Exit Sub
            Case "USER"
                pageerrorlbl.Text = "Sorry! The User Name You have entered already exist. Please Contact the Web Admin if you think this is a mistake."
                Exit Sub
            Case "EMAIL"
                pageerrorlbl.Text = "Sorry! The Email Address You have entered already exist. Please Contact the Web Admin if you think this is a mistake."
                Exit Sub
            Case "INSERT" Or "SUCCESS"
                Sqlcommand.CommandText = sqlinsert
                Sqlcommand.Connection = Sqlconnection
                Sqlcommand.ExecuteNonQuery()
                Response.Redirect("confirmreg.aspx")
                Exit Select
            Case "FAILED"
                pageerrorlbl.Text = "Sorry! Something is wrong. Please contact the administrator"
                Exit Select
            Case Else
                pageerrorlbl.Text() = "SKIPPED EVERYTHING"
                Exit Select
        End Select

Hmm for some reason this didnt' work. it still skipped to SKIPPED EVERYTHING.

Put a break point in the following line.

Select Case errmessage

And see the value of the variable 'errmessage'.

Hmm for some reason i commented out all the Select case info and then told it to display the errmessage under pageerrlbl.text, however this didn't work either.

I got this err message:

Conversion from string "ctyokley" to type 'Long' is not valid.

I am unaware of what this means. Could you please tell me?

The issue is with this line Case "INSERT" Or "SUCCESS". Rewrite this line as Case "INSERT", "SUCCESS". This should work.

So i did what Lorie said, however it still gave teh same error with the ctyokley string. it doesn't give a line tho. not sure what that is.

Ok so i have eliminated the problem to the function of the sqlcheckuser. For some reason, when i run the following function:

Function SQLCHECKUSER() As Object
        Dim query1 As String = "SELECT [User_Name] FROM [FDXUSER] WHERE ([User_Name] ='" & User_Name.Text & "')"
        Dim query2 As String = "SELECT [employee_number] FROM [FDXUSER] WHERE ([employee_number] ='" & empnumber.Text & "')"
        Dim query3 As String = "SELECT [Email] FROM [FDXUSER] WHERE ([Email] ='" & email_address.Text & "')"
        Dim sqlcommand As New OleDbCommand(query1, Sqlconnection)
        Dim sqlcommand2 As New OleDbCommand(query2, Sqlconnection)
        Dim sqlcommand3 As New OleDbCommand(query3, Sqlconnection)
        Dim obj As Object
        Dim obj2 As Object
        Dim obj3 As Object

        obj = sqlcommand.ExecuteScalar()
        obj2 = sqlcommand2.ExecuteScalar()
        obj3 = sqlcommand3.ExecuteScalar()
       
        If obj Or obj2 Or obj3 Is Nothing Then
            Return errmessage = "SUCCESS"
        Else
            If obj Is Nothing Then
                Return errmessage = "INSERT"
            Else
                Return errmessage = "USER"
            End If
            If obj2 Is Nothing Then
                Return errmessage = "INSERT"
            Else
                Return errmessage = "EMPLOYEE"
            End If
            If obj3 Is Nothing Then
                Return errmessage = "INSERT"
            Else
                Return errmessage = "EMAIL"
            End If

        End If

    End Function

It comes back and says error.... becuase i run a TRY END TRY with a catch ex as message. and the error says "Conversion from string "ctyokley" to type 'Long' is not valid. "

Somewhere withing that function is my error, but i'm not sure what. Any clue? I tried the textbox.text.tostring and that didnt' work... now i dont kno any other suggestions.

Ok so the Case problem has been solved. Now i am openin up another thread to help out with that function problem.
