You may use Excel Help--> Contents-- MS Excel Visual Basic Reference to became more familiar. (Though some Basic2FoxPro code transaction skill is in need.)



>Second question:

>excelbut.init()
>objExcel= CREATEOBJECT("Excel.Application")
>lcFile = "C:\SourceVam\Special Clients\RessortCharland\transfertStock\Info.xls"
>objBook = objExcel.WorkBooks.Open(lcFile)

>exccelbut.click()
>objExcel.Visible = .t.

I would put procedure into the click method.
Do not forget to close workbook, quit excel and release Excel objects

objBook.Close
objExcel.Quit
release objexcel


>What would be the impact on memory usage and speed?
It depends on what your user should do with Excel file. I would give him/her the file, and force him/her to close it before go further with foxpro.
