Hello wold :-)
Somebody can give me an exemple of code witch I can force a macro button on an sheet ?

Some explanation:
I have a sheet with a macro-button "CALCULATE"
In the code of SUB CALCULATE I want to provide code to make visible a macro-butto with the name "NEXT CALCULATION ?" for exemple
so....this new macro button may only be visible when the first calculation is done.
(In my project the new macro-button has to come on CELL I8)

I want to add this information.(also code on this sheet )
In my code I provided some code to give a "new name" to created sheet . (exemple: Calculation1...calculation 2 .....)
Maybe we can work with this information ??
In the workbook I hav 1 sheet visisble ans 6 sheets invisible and protected. So......the startnumber = 7 sheets

'GIVE THE NEW CALCULATION AN UNIQUE NUMBER
Dim sht As Worksheet, nsht As Worksheet
Dim nm As String, num1 As Integer, num2 As Integer
Dim tmp As Variant

For Each sht In ActiveWorkbook.Sheets
If Left(sht.Name, 8) = "Voorstel" Then
tmp = Split(sht.Name)
num1 = tmp(UBound(tmp))
If num1 > num2 Then num2 = num1
End If
Next sht
nm = "Calculation " & (num2 + 1)
Sheets("Calculate").Copy After:=Sheets(Sheets.Count)
ActiveSheet.Name = nm

I'm looking to your suggestions....
Thanks a lot
