vba - How to properly write and save a new Excel file?

Question

An application (a SCADA program) has an event that trigers every day and run a script that writes an Excel file (one for each day). The file could contain multiple sheets.

On Windows 7, with Office 2007 installed, I can write, but I can't save and neither quit the Excel.Application.

Dim objExcel as Object
Set objExcel = CreateObject("Excel.Application")
objExcel.WorkBooks.Add  'I think I shouldn't do this, but if not it doesn't work

Set sheet = objExcel.ActiveWorkBook.Worksheets.Add
'writing to the actual sheet...

objExcel.ActiveWorkBook.SaveAs path$
objExcel.Workbooks.Close
objExcel.Quit   

If I run the script manually (from the script editor):

• it saves
• the Excel process still runing
• When I open the Excel file (not from script), this has 2 workbooks, the actual and the last one from the last execution.

If I try trigger the event:

• error occurs on the line when it saves

Answer 1

Solved.

Dim objExcel as Object
Dim sheet as Object
Set objExcel = CreateObject("Excel.Application")
objExcel.WorkBooks.Add

Set sheet = objExcel.ActiveWorkBook.Worksheets.Add
'writing to the actual sheet...

path$ = "path/must/use/slash/insteed/of/backslash"

objExcel.ActiveWorkBook.SaveAs path$
objExcel.ActiveWorkBook.Close
objExcel.Quit  
Set objExcel = Nothing    

So the problem was the path$ and I forgot to put Set objExcel = Nothing. Thats all.
