I think it will allow that if the file "text.txt" is in the same directory the executable is ran from? Is that the case?

Because it's broken.

For more specific help, ask a more specific question, which probably means posting some code, as well as telling us what *does* happen ( does the form run at all ? does it crash ? )

int rowNumber = 3;<br />
            int cellNumber = 2;<br />
<br />
            bool b = (bool)dataGridView1.Rows[rowNumber].Cells[cellNumber].Value;

But one tricky thing is here: if a value you are getting was not set (nobody checks or unchecks this checkbox) the value of it is null. We need handle this case.

            int rowNumber = 3;<br />
            int cellNumber = 2;<br />
<br />
            bool b = false;<br />
            if (dataGridView1.Rows[rowNumber].Cells[cellNumber].Value != null)<br />
            {<br />
                b = (bool)dataGridView1.Rows[rowNumber].Cells[cellNumber].Value;<br />
            }<br />

You want to see if the user has a file on the local machine from an ASP web page? Can't do it, you don't have file access rights to the local machine from a web page.

ActiveX has file rights I think. Not sure, why do you need to do this from a web application.

I wouldn't thank me yet, make sure it does what you need it to. I still don't understand why you are doing that check.
