Is there a way to make my app behave differently in case Excel is not installed (for eg. detect the error and display a message ?)

Microsoft.Office.Excel._Application app = null;
try
{
  app = new Microsoft.Office.Excel._Application();
}
catch
{
// COM object cannot be created

For some reason when I save my database it tries to convert the Home Phone, Cell Phone, and Fax into System.Int32. I have them set on System.String.

Like I said in the database the textbox is set to System.String

if you use return; that will exit the foreach loop won't it?

Jacob Dixon wrote:

Where the return; would be then it would go down here to the next If statement

Yes! Thanks! As long as it skips the Else statement that is right after the IF statement!

if (some expression is true)
{
    // Do this
}
else // the above expression was false
{
    // Do this instead
}

if (DBNull.Value == r.Cells[3].Value);
else richTextBox1.Text += string.Format("{0}\n", r.Cells[3].Value.ToString());

if (DBNull.Value != r.Cells[3].Value)
    richTextBox1.Text += string.Format("{0}\n", r.Cells[3].Value.ToString());

Jacob Dixon wrote:

the problem with this is if Cells[12] was actually DBNull, then for some reason it would skip the richTextBox1.Text += "\n\n";

When I enter like: 123-4567 it doesn't because of the dash.
