how to open a Workbook and activate a specific sheet
 

I have a situation... where I have to open workbook1 which has 10 sheets
(sheet1...sheet10) from another workbook2 using different commandbuttons.
The question is how do I open workbook1 and activate different sheets
based
on the command button. Is there anyway to pass the sheet name as an
argument.
or Are there any other methods? My workbook1 does have an auto_open macro.

One way would be to have radio buttons in workbook2 which store the index of
the selected button in a cell
then when the Load Workbook command button is clicked it will open the
desired workbook and select the
sheet specified.

This code run from the command button ...

Sub Button1_Click()
Dim sheetnum
sheetnum = [a1]
Workbooks.Open Filename:="TestBook1.xls"
Sheets("Sheet" & sheetnum).Select

End Sub
