This works from a type name in a cell.
Will activate or open if closed.

Sub GetWorkbook()
If ActiveCell.Value = "" Then Exit Sub
workbookname = ActiveCell.Value
On Error GoTo OpenWorkbook
Windows("" & workbookname & ".xls").Activate
Exit Sub
OpenWorkbook:
Workbooks.Open(workbookname & ".xls").RunAutoMacros xlAutoOpen
Exit Sub
End Sub

Hello.
I'm trying to do 2 things that i explain right away:
1 - I trying to do a VBA function that when you click on a
button, first checks if a certain file is already open,
and if this is true then it doesn't do nothing, and if its
false it opens the file.

2 - How can i open the Start-Run-Browse window with VBA
code?

Thanks
