Re: Excel 2002 UDF screen tips

There are a couple of ways, one not too robust, one that requires a dll.

The not too robust way, suggested by Laurent Longre and working for two
parameters is :-
Const Lib = """c:\windows\system\user32.dl限l"""
Option Base 1

Private Function Multiply(N1 As Double, N2 As Double) As Double
Multiply = N1 * N2
End Function

'=============================限=============

Private Function Divide(N1 As Double, N2 As Double) As Double
Divide = N1 / N2
End Function

'=============================限=============

Sub Auto_open()

Register "DIVIDE", 3, "Numerator,Divisor", 1, "Division", _
"Divides two numbers", """Numerator"",""Divisor """, "CharPrevA"
Register "MULTIPLY", 3, "Number1,Number2", 1, "Multiplication", _
"Multiplies two numbers", """First number"",""Second number """, _
"CharNextA"

End Sub

'=============================限=============

Sub Register(FunctionName As String, NbArgs As Integer, _
Args As String, MacroType As Integer, Category As String, _
Descr As String, DescrArgs As String, FLib As String)

Application.ExecuteExcel4Macro _
"REGISTER(" & Lib & ",""" & FLib & """,""" & String(NbArgs, "P") _
& """,""" & FunctionName & """,""" & Args & """," & MacroType _
& ",""" & Category & """,,,""" & Descr & """," & DescrArgs & ")"

End Sub

'=============================限=============

Sub Auto_close()

Dim FName, FLib
Dim I As Integer
FName = Array("DIVIDE", "MULTIPLY")
FLib = Array("CharPrevA", "CharNextA")
For I = 1 To 2
With Application
.ExecuteExcel4Macro "UNREGISTER(" & FName(I) & ")"
.ExecuteExcel4Macro "REGISTER(" & Lib & _
",""CharPrevA"",""P"",""" & FName(I) & """,,0)"
.ExecuteExcel4Macro "UNREGISTER(" & FName(I) & ")"
End With
Next

End Sub

The dll solution:
Also from Laurent Longre, you use the FUNCUSTOMIZE utility .Get it at
