David,

From the Vbaxl8.hlp file expression.Open(FileName, UpdateLinks, ReadOnly, Format, Password, WriteResPassword, IgnoreReadOnlyRecommended, Origin, Delimiter, Editable, Notify, Converter, AddToMRU)

This works for me:

olewbook.open("C:\My Documents\umr address.xls", , , , , , .t. )

>I've used the following code to open up an excel workbook.
>
>oleapp = createobject('excel.application')
>oleapp.visible = .t.
>olewbook = oleapp.workbooks
>olewbook.open('p:\test.xls')
>
>If the workbook is already opened up by someone else prior to running the above code and error is generated when the line "olewbook.open('p:\test.xls')" is executed. Foxpro can't open up the file for read/write because someone else has it opened. How can I test if the excel workbook is opened by someone else before running this code?
