was it in C# that you could have code in your program to give you the line and collumn that an error occured? i have an error handler but i do not know where the error is coming from.

if your error is a compile error, just double click on the error in Error List window.
and if your error is runtime, you can write a try/catch block and with the exception argumant you can get the details of error
for example

try
{
    // your code goes here
}

catch(exception ex)
{

   // with ex.StackTrace you can get the error details if
   // any error occure in your try block
   // note, ex.Message just will give you a string message about
   // exception such as "input string was not in a correct format"
   // if a format exception was thrown

}

If you are running a debug copy of the file, and have the .pdb file with the application then the Exception.ToString() method should give you filenames and line numbers for where errors occurred.
