All UK dialling codes have already changed to a new format.
Until 16th April 1995 the old codes can still be used, but
after that you may find yourself wasting a lot of time 
listening to wrong number messages, especially for those
areas where the new code bears little or no relationship to
the old one.
 
This small VB program demonstrates use of BSFONDAY. This 
DLL provides a function which converts existing UK phone 
number codes to their new form. The function is named 
PhoneDay and indexed 1 in the DLL.

The syntax of the function is as follows:

Function PhoneDay  (OldNumber, NumFormat: Pointer;
                    BufferSize: Integer;						
                    NewNumber: Pointer): Integer

Return Value - 0 (false) = cannot convert number
               Positive = number of chars in new number

You must allocate a return buffer NewNumber of size BufferSize
before calling the function. It returns the number of chars in
the new number, or zero if the conversion fails. The parameter 
NumFormat controls the format of the returned number. Set it 
to a string containing numerics and separators as required, 
the default is '9999-999-9999'. You can include prefixes such 
as 'Tel: 99999-999999'. The function correctly handles all UK
codes and the international dialling prefix. It also preserves
any trailing text such as 'Ext.256', and alternative number 
suffixes such as '0121-123-4567 / 6' or '0152 223 456 and 458'.

Example use in Visual Basic.


In declarations section - (all on one line) :

Declare Function PhoneDay% Lib "bsfonday.dll" (ByVal OldNumber$,
          ByVal NumFormat$, ByVal BufferSize%, ByVal NewNumber$)

To use the function:

   Dim NewNum$, OldNum$, FmtStr$
   Dim RET%
   OldNum = txtOldNum     ' from Old Number text box
   FmtStr = cboFormat     ' from Format String text box
   NewNum = String(50, " ")
   RET = PhoneDay(OldNum, FmtStr, 49, NewNum)
   If RET > 0 Then
      lblNewNum = Left(NewNum, RET)   ' Converted Number
   Else
      lblNewNum = "Invalid"
   End If
