Excel automation and delete sheet

I have set up an Excel automation routine that works very well thanks to the help of other NOLUG posts that I have read.

The problem that I am having now, is that if I pass the command to delete a worksheet, it asks me to confirm that deletion. I would like it to just do it without asking. Any way to do this?

Here is the code that I am using:
Vars -
Name DataType Subtype Length
xlApplication Automation 'Microsoft Excel 9.0 Object Library'.Application
xlWorkbook Automation 'Microsoft Excel 9.0 Object Library'.Workbook
xlWorkSheet Automation 'Microsoft Excel 9.0 Object Library'.Worksheet

Code -
xlWorkbook := xlApplication.Workbooks.Add;
xlSheets := xlWorkbook.Worksheets;
xlWorkSheet := xlSheets.Item('Sheet3');
