How can I break down text in letters using VBA

[Berend Botje]

Hi,

I have a Excel sheet in which text is to be typed by the user. The tex
must be broken down in single letters, which the program recognises.

For example:

User types: Fox

Program:
1: Take first letter
2: Check what letter it is
3: Use letter in script (for example a if then statement)
4: Take next letter
5: Repeat steps 2 to 5 untill all text is analysed

Can anyone tell me how to do this? The breaking down of the text, tha
is.....

Thanks beforehand,

Berend Botj

Hi Berend,

As an example try:

Sub Tester()
Dim sStr As String
Dim i As Long

sStr = "FOX"

For i = 1 To Len(sStr)
MsgBox Mid(sStr, i, 1)
Next
End Sub

Use the Mid() function to breakdown the text string. Use a Select construct
to evaluate the value and execute corresponding code.

Troy

Sub Test1()
Dim ii As Integer
Dim sText As String
Dim sTemp As String

sText = "fox"
For ii = 1 To Len(sText)
sTemp = Mid(sText, ii, 1)
Select Case sTemp
Case "f"
MsgBox "letter = f"
Case "o"
MsgBox "letter = o"
Case "x"
MsgBox "letter = x"

'add additional cases.

Case Else
'no-match special case.
End Select
Next ii
End Sub

Hi Berend,

This will trap the input and process each letter. You will need to fill out
the action to be taken

Private Sub Worksheet_Change(ByVal Target As Range)
Dim i As Long

On Error GoTo ws_exit:
Application.EnableEvents = False
If Not Intersect(Target, Me.Range("A1:H10")) Is Nothing Then
With Target
For i = 1 To Len(.Value)
Select Case LCase(Mid(.Value, i, 1))
Case "a": 'handle a
Case "b": 'handle b
Case "c": 'handle c
'etc.
End Select
End If
End With
End If

ws_exit:
Application.EnableEvents = True
End Sub

'This is worksheet event code, which means that it needs to be
'placed in the appropriate worksheet code module, not a standard
'code module. To do this, right-click on the sheet tab, select
'the View Code option from the menu, and paste the code in.

According to the times on the postings, Bob posted his two minutes before
you said it was working.
