What you need to do is to loop thru your original string one character at a time and keep the character if it is not numereic. This will do it:

Expand|Select|Wrap|Line Numbers
  1. Dim OldString As String
  2. Dim NewString As String
  3. NewString = ""
  4. OldString = "ab9cd12e3"
  5.  
  6. For I = 1 To Len(OldString)
  7.   If Not IsNumeric(Mid(OldString, I, 1)) Then
  8.      NewString = NewString & (Mid(OldString, I, 1))
  9.   End If
  10. Next I 
  11.  
Good Luck!

Hi
Thank u for the kind reply. But i tried that code. i will explain what i am doing. i have a database and the main table got a field which holds records like abcd1234, ghj36789. i want to create a new table using a module with a single field that should have only the alphabet part of the main table like abcd, ghj.
i can create a table using a module, but i tried your code but no effect.
Hope you can help me pls..........

Hi, I added to the previous code posted to help you loop through the main table and store the new strings into your second table. Make sure you have the second table created with the single field before attempting this.

Expand|Select|Wrap|Line Numbers
  1. Private Sub cmdRun_Click()
  2.     Dim OldString As String
  3.     Dim NewString As String
  4.     Dim rstAlpha As Recordset
  5.     Dim rstAlphaNum As Recordset
  6.     Dim I As Integer
  7.  
  8.     Set rstAlpha = CurrentDb.OpenRecordset("tblAlpha", dbOpenDynaset)
  9.     Set rstAlphaNum = CurrentDb.OpenRecordset("tblAlphaNum", dbOpenDynaset)
  10.  
  11.     rstAlphaNum.MoveFirst
  12.  
  13.     Do While rstAlphaNum.EOF = False
  14.         OldString = rstAlphaNum![alphaNum]
  15.         NewString = ""
  16.         For I = 1 To Len(OldString)
  17.           If Not IsNumeric(Mid(OldString, I, 1)) Then
  18.              NewString = NewString & (Mid(OldString, I, 1))
  19.           End If
  20.         Next I
  21.         rstAlpha.AddNew
  22.         rstAlpha![alpha] = NewString
  23.         rstAlpha.Update
  24.         rstAlphaNum.MoveNext
  25.     Loop
  26. End Sub
  27.  
Notes:
tblAlphaNum is your main table and [alphaNum] is the field containing your alpha numeric code
tblAlpha will be your second table and [alpha] is the field you want to store your new alpha codes in

Hope this helps set you in the right direction.
