Calculate words value in vb.net - vb.net

Question

I have a textbox on a form where the user types some text. Each letter is assigned a different value like a = 1, b = 2, c = 3 and so forth. For example, if the user types "aa bb ccc" the output on a label should be like:
aa = 2
bb = 4
dd = 6
Total value is (12)
I was able to get the total value by looping through the textbox string, but how do I display the total for each word. This is what I have so far:
For letter_counter = 1 To word_length
letter = Mid(txtBox1.Text, letter_counter, 1)
If letter.ToUpper = "A" Then
letter_value = 1
End If
If letter.ToUpper = "B" Then
letter_value = 2
End If
If letter.ToUpper = "C" Then
letter_value = 3
End If
If letter.ToUpper = "D" Then
letter_value = 4
End If
If letter.ToUpper = "E" Then
letter_value = 5
End If
If letter.ToUpper = " " Then
letter_value = 0
End If
totalletter = totalletter + letter_value
Label1.Text = Label1.Text & letter_value & " "
txtBox2.Text = txtBox2.Text & letter_value & " "
Next letter_counter

Answer 1

This simple little routine should do the trick:
Private Sub CountLetters(Input As String)
Label1.Text = ""
Dim total As Integer = 0
Dim dicLetters As New Dictionary(Of Char, Integer)
dicLetters.Add("a"c, 1)
dicLetters.Add("b"c, 5)
dicLetters.Add("c"c, 7)
For Each word As String In Input.Split
Dim wordtotal As Integer = 0
For Each c As Char In word
wordtotal += dicLetters(Char.ToLower(c))
Next
total += wordtotal
'Display word totals here
Label1.Text += word.PadRight(12) + "=" + wordtotal.ToString.PadLeft(5) + vbNewLine
Next
'Display total here
Label1.Text += "Total".PadRight(12) + "=" + total.ToString.PadLeft(5)
End Sub

Answer 2

This should give you an idea:
Dim listOfWordValues As New List(Of Integer)
For letter_counter = 1 To word_length
letter = Mid(txtBox1.Text, letter_counter, 1)
If letter = " " Then
totalletter= totalletter + letter_value
listOfWordValues.Add(letter_value)
letter_value = 0
Else
letter_value += Asc(letter.ToUpper) - 64
End If
Next letter_counter
totalletter = totalletter + letter_value
If Not txtBox1.Text.EndsWith(" ") Then listOfWordValues.Add(letter_value)
txtBox2.Text = txtBox2.Text & string.Join(", ", listOFWordValues);

You can try something like this. Assuming txtBox1 is the string the user enters and " " (space) is the word delimiter:
Dim words As String() = txtBox1.Text.Split(New Char() {" "}, StringSplitOptions.RemoveEmptyEntries)
Dim totalValue As Integer = 0
Dim wordValue As Integer = 0
For Each word As String In words
wordValue = 0
For letter_counter = 1 To word.Length
Dim letter As String = Mid(txtBox1.Text, letter_counter, 1)
Select letter.ToUpper()
Case "A":
wordValue = wordValue + 1
Case "B":
wordValue = wordValue + 2
' And so on
End Select
Next
totalValue = toalValue + wordValue
Next
The above code first takes the entered text from the user and splits it on " " (space).
Next it sets two variables - one for the total value and one for the individual word values, and initializes them to 0.
The outer loop goes through each word in the array from the Split performed on the user entered text. At the start of this loop, it resets the wordValue counter to 0.
The inner loop goes through the current word, and totals up the values of the letter via a Select statement.
Once the inner loop exits, the total value for that word is added to the running totalValue, and the next word is evaluated.
At the end of these two loops you will have calculated the values for each word as well as the total for all the worlds.
The only thing not included in my sample is updating your label(s).

Try this ..
Dim s As String = TextBox1.Text
Dim c As String = "ABCDE"
Dim s0 As String
Dim totalletter As Integer
For x As Integer = 0 To s.Length - 1
s0 = s.Substring(x, 1).ToUpper
If c.Contains(s0) Then
totalletter += c.IndexOf(s0) + 1
End If
Next
MsgBox(totalletter)

I would solve this problem using a dictionary that maps each letter to a number.
Private Shared ReadOnly LetterValues As Dictionary(Of Char, Integer) = GetValues()
Private Shared Function GetValues() As IEnumerable(Of KeyValuePair(Of Char, Integer))
Dim values As New Dictionary(Of Char, Integer)
Dim value As Integer = 0
For Each letter As Char In "ABCDEFGHIJKLMNOPQRSTUVWXYZ"
value += 1
values.Add(letter, value)
Next
Return values
End Function
Public Function CalculateValue(input As String) As Integer
Dim sum As Integer = 0
For Each letter As Char In input.ToUpperInvariant()
If LetterValues.ContainsKey(letter) Then
sum += LetterValues.Item(letter)
End If
Next
Return sum
End Function
Usage example:
Dim sum As Integer = 0
For Each segment As String In "aa bb ccc".Split()
Dim value = CalculateValue(segment)
Console.WriteLine("{0} = {1}", segment, value)
sum += value
Next
Console.WriteLine("Total value is {0}", sum)
' Output
' aa = 2
' bb = 4
' ccc = 9
' Total value is 15
