Question

Command line has a string limitation as mentioned on msdn and here.

I tried the workaround suggested on msdn, writing the arguments to a file. But, I am unable to pass the arguments from a file.

Edit :
I need to run the bcp utility, in order to export (huge) data to flat files.

Answer 1

The executable you’re running has to support this explicitly. For example, the C# compiler allows you to write

csc @foo

to load some options from a file called foo. I don’t believe this can easily be “fixed” without support from the command you’re running though… it’s possible that you could write a small wrapper program which loaded the file and started the process itself. However, you’d have to be careful in terms of security handles, propagating console input and output etc. If you’re in control of the application in question, you’d be much better off putting support in directly.
