How to remove some characters and spaces from a title?

I'm creating a CD database program, and I want users to enter a title for their CD's. Then I will create a directory for that title with the same name as the title.

But directories cannot contain the characters :/\ etc. So how do I strip a title from these characters as well as any spaces?

Thanks for any help!

If you use vb6 you can use the replace function:

myString = Replace(myString,"'","")
that removes all ' and replaces them with nothing

VB5

Code:

---


Option Explicit
Option Compare Text



'Author of function:  John Percival
'Origin: http://www.vb-world.net/tips/tip110.html
'Purpose: A Find-and-Replace function for VB5 users
'Version: VB5+

'function to do the work

Public Function replaceall(searchstring As String, _
    findstring As String, replacestring As String) As String

Dim curpos As Long

curpos = 1

Do

curpos = InStr(curpos, searchstring, findstring)
searchstring = Left$(searchstring, curpos - 1) & _
replacestring & Right$(searchstring, Len(searchstring) _
- curpos - Len(findstring) + 1)

Loop Until InStr(searchstring, findstring) = 0

replaceall = searchstring

End Function

'call to get the work done
'x = string to be searched
'y = what to search for
'z = what to replace it with

Private Sub Command1_Click()

Dim x As String, y As String, z As String

x = "What in the world are we Searching for here, anyway?"
y = "Searching for"
z = "Replacement Value"
Call replaceall(x, y, z)
MsgBox x

End Sub

---

If you're using VB6 then you can use the Replace function.

Code:

---

'spaces
Text1.Text = Replace(Text1.Text, " ", "")
'colon
Text1.Text = Replace(Text1.Text, ":", "")
'slash
Text1.Text = Replace(Text1.Text, "/", "")
'and so on

---

Gl,
D!m

try this:

Code:

---

Private Declare Function StrSpn Lib "SHLWAPI" Alias _
  "StrSpnW" (ByVal psz as Long, ByVal pszset as Long) as Long

Public Function IsAlphaNumeric(ByVal sString as String) as Boolean
Dim lPos as Long
Const ALPHA_NUM as String = "abcdefghijklmnopqrstuvwxyz" & _
  "ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789"

  'Returns the first occurrence of nonmatching characters
  lPos = StrSpn(StrPtr(sString), StrPtr(ALPHA))
  ' If the return position is not equal to the length of the
  ' input string, non-alpha chars were found.
  IsAlphaNumeric = (lPos = Len(sString))

End Function

---

then you can use the function like this:

Code:

---

If IsAlphaNumeric(myText.text) = False Then
  MsgBox "Sorry. Special Characters Not Allowed."
End If

---

hope this helps. :)

Code:

---

Option Explicit

Sub Main()
  'PURPOSE: Test Data
  Dim str_Data As String
  str_Data = "How are you today?"

  'PURPOSE: Illegal Characters
  Dim str_IllegalChar As String
  str_IllegalChar = "\/:*?""<>|"
 
  Dim str_Char As String
  Dim int_X As Integer
  For int_X = 1 To Len(str_Data)
    str_Char = Mid(str_Data, int_X, 1)
    If InStr(1, str_IllegalChar, str_Char) <> 0 Then
      MsgBox str_Char
    End If
  Next
End Sub

---

Well, I am using VB6 so the first option worked great.

Thanks to you all!
