Hi Nathaniel,

The root problem is that the string returned by the GetOpenFilename
method is not the same as the Window name of that file once it has been
opened. Here's one way of rewriting your code that will solve this problem.

Public Sub Main()

Dim f_name As Variant
Dim wkbBook As Workbook

f_name = Application.GetOpenFilename("Text Files (*.txt), *.txt")
If f_name < False Then MsgBox "Open " & f_name

Workbooks.OpenText Filename:=f_name, Origin:= _
xlWindows, StartRow:=1, DataType:=xlFixedWidth,
FieldInfo:=Array(Array(0, _
2), Array(17, 2), Array(30, 2), Array(39, 2))

Set wkbBook = ActiveWorkbook
Workbooks.Open Filename:="c:\switch_makros\Switch_Temp.xls"
Sheets("Sheet1").Select
Temp wkbBook

End Sub

Public Sub Temp(ByRef wkbBook As Workbook)
wkbBook.Activate
End Sub
