One of the best thing things you can do, when programming, is validate user input. This can save you all kinds of headache in the long run - problems with database inserts/updates, problem with SQL Injection, problems with variables types not being what you expect.

In this article, I am going to show you how to take a string and return just the numbers from it. Stripping all alphabetical and symbols from it. 

Function StripAlphaChars(ByVal pstrSource)
Dim m_strOut
	m_strOut = Trim(pstrSource & "")
Dim m_objReg
	Set m_objReg = New RegExp

		m_objReg.Pattern = "\D"
		m_objReg.Global = True
		m_objReg.IgnoreCase = True
		'm_objReg.MultiLine = True

		m_strOut = m_objReg.Replace(m_strOut, "")

	Set m_objReg = Nothing

	StripAlphaChars = m_strOut

End Function
