Hi,

I retrieve a list of arguments for a stored procedure from ORACLE using
OracleDataAdapter. These populate a listbox on a form.

Then when the user selects the argument from the listbox, I want to allow
the user to set a value for the selected argument.

But when I try to do this step, I always get an error:
System.InvalidOperationException - Operation is not valid due to the current
state of the object.   

Can anyone help me?

thanks,

Philip

You will need to post some code and identify where in the code the exception occurs.
