>I do a lot of Excel automation. So much that I have a standard stack of commands that I use over and over. oExcel = CreateObject("Excel Application") etc etc. Make an oBook object. Make an OSheet object. Get number of used rows. Iterate through the rows. Do something with the data. Close the Book. Quit Excel. and set the oExcel object to NULL.

Or (just thinking of another way) should I put the code into a try catch construct? The disadvantage of Try Catch is that interactive debugging is hobbled.

BTW, killing an application doesn't seem like a right way to deal with the problem.
