Adding contents of text file to the code

Hello, I have a text file, which looks like this:

Code:

---

1=Hello
2=Bye
3=Tomorrow
4=Yesterday
5=Sunday
etc
etc
etc

---

If my application returns a "3" then it extracts the text file from the application (resource file), reads it and shows the corresponding text (in this case "Tomorrow").

I'd like to get rid of the text file and add the list of text to the code, but I don't know how to do this. Basically I want to check the list internally for the number and show the corresponding text.

Do I need to add the list as one huge string or how would I do this?

VB Code:

Select Case SomeVariable
Case 1
    MsgBox "Hello"
    'or some thing else
Case 2
    MsgBox "Bye"
Case 3
    MsgBox "Tomorrow"
Case 4
    MsgBox "Yesterday"
Case 6
    MsgBox "Sunday"
'Case etc
'    MsgBox "etc"
'etc
'etc
End Select

Change to Public Const's For use within a Module.

VB Code:

Private Const str1 As String = "Monday"
Private Const str2 As String = "Hello"
Private Const str3 As String = "What"
Private Const str4 As String = "This"
Private Const str5 As String = "That"
 
Private Sub Command1_Click()
 
    Const Something As Integer = 1
    Select Case Something
        Case 1
            MsgBox "1-" & str1
        Case 2
            MsgBox "2-" & str2
    End Select
    
End Sub

OR

VB Code:

Private strArray(5) As String
 
Private Sub Command1_Click()
    
    Dim e As Integer   
    strArray(1) = "Monday"
    strArray(2) = "Hello"
    strArray(3) = "What"
    strArray(4) = "This"
    strArray(5) = "That" 
    For e = 1 To 5
        Select Case e
            Case 1
                MsgBox "1-" & strArray(e)
            Case 2
                MsgBox "2-" & strArray(e)
        End Select
    Next e
    
End Sub

OR

VB Code:

Private Const strList As String = "Monday,Hello,What,This,That"
Private strArray As Variant
 
Private Sub Command1_Click()
  
    Dim e As Integer
    strArray = Split("," & strList, ",")
    For e = 1 To UBound(strArray)
        Select Case e
            Case 1
                MsgBox "1-" & strArray(e)
            Case 2
                MsgBox "2-" & strArray(e)
        End Select
    Next e
 
End Sub

Thank you, cssriraman.

The list is quite long. Is there a way to put each Case on one line?

Something like this:

VB Code:

Select Case SomeVariable
Case 1 sString = "Hello"
Case 2 sString = "Bye"
Case 3 sString = "Tomorrow"
Case 4 sString = "Yesterday"
Case 5 sString = "Sunday"
End Select

Thanks rory, but the text file contains a few hundred lines (18kb) and that requires me to add twice as much "text" as I had with the text file.

Even though you put in one line the execution time or memory will be same

Anyway, you can do that using colons :

VB Code:

Select Case SomeVariable
Case 1 : sString = "Hello"
Case 2 : sString = "Bye"
Case 3 : sString = "Tomorrow"
Case 4 : sString = "Yesterday"
Case 5 : sString = "Sunday"
End Select

When you have received an answer to your question, please mark it as resolved using the Thread Tools menu.

Thanks again, cssriraman. I just prefer to have it as a list. It makes it a bit easier for me to edit the list if needed.

Btw, is the execution time and memory usage of doing it this way the same as reading it from a text file or not? If not, is there much difference?

Agreed, extra little bit of code, but easier to edit that text in the future.
As you see below its a small loop instead of Select Statements.

VB Code:

'// MAIN CONFIG MODULE
Public strArray(5) As String
Public SomeVariable As Integer
 
'// START UP SUB
Public Sub  ProgramStart()
    strArray(1) = "Monday"
    strArray(2) = "Hello"
    strArray(3) = "What"
    strArray(4) = "This"
    strArray(5) = "That" 
End Sub
 
'// IN YOUR FORM
Private Sub Command1_Click()
    
    Dim e As Integer   
    For e = 1 To 5
        If SomeVariable = e Then
           sString = strArray(e)
        End If
    Next e
    
End Sub

Thank you, rory :)

I still would like to know if doing this internally makes much difference in execution time and memory usage compared to reading from a text file.

It increases memory usage and decreases execution time. If 18k makes the difference between running and not running you need a new computer. If reading a few lines from a text file (actually you can read the entire file into memory in one shot) makes an appreciable difference in execution time, you also need a new computer.
