I am writing a Visual C++ 6.0 client which need to launch Excel and
display some data using Excel COM automation interface. How can I
programmatically set the column width of a particular column (e.g.
column 3) in Excel?

I can easily achieve this in VB as follow:

sheet.Columns(3).ColumnWidth = 40

But I cannot do this in C++ because the method

LPDISPATCH _Worksheet::GetColumns()

does not take any argument. I believe this method return a Range
object.

How can I set the width of column 3 using C++?

Thanks
