Try the macro recorder, it will give you a good start point. The recorder is used by many users, from begginers to advanced...
Here is what the macro recorder came up after i manually pasted a link:
Code:
Sub Macro1()
'
' Macro1 Macro
'
'
Windows("diverse calcule.xls").Activate
Range("F11").Select
Selection.Copy
Windows("New Microsoft Excel Worksheet.xlsx").Activate
Range("D21").Select
ActiveSheet.Paste Link:=True
End Sub
