hi,
i am getting an exception while populating the data in the datagrid.
am getting the values into datatable and binding it to the datagrid but it is not
displaying the data and giving an exception like
System.Argument Exception: Empty path name is not legal.

That error message relates to File IO. That doesn't seem like something that would happen from a databind.
Check the line location for the error and post the code associated with it?

I am going out a limb here, but you have a StreamWriter somewhere. On the initialization of that StreamWriter, you passed an empty string as the file location.
Something like: -
string FileLocation;
-
StreamWriter SWriter = new StreamWriter(FileLocation);
-
That will throw just that exception.

Hello all,
I am writing a script where I need to use the system() function to call

(see attached file, test.php). When my webserver runs that part of the

I don't get an error message or anything...it just returns a "1"
(whereas it should return a "0") as far as I can tell. I have read the

Hello everyone,
I have an applciation that uses remoting. When the application is run

use
ConfigurationSettings.AppSettings with no problem.
