Even if we aren’t able to find an alternative API for CreateFile, our issue solved by using CreateDirectory instead of CreateFile to check whether USB is writable or not.

Thank You.

if try and catch logic is available in C++ maybe you can use that... just a wild guess hoping i could help. :-)

Sorry.I didn't get you.

in .net there is an option called try and catch.. so any problem within code that was written inside the try statement.. .net will fire it in catch statement telling what seems to be the problem.
so in your case.. upon writing in the usb and during writing there is a problem it will fire in catch statement.. like onerror go to.. something like that..

try catch bolcks are present in c++
My problem is not createfile getting failed.
But an alternate method for CreteFile API.

Actully I need to check whether the inserted USB media is writable.
Currently CreateFile API is used for that.
I need to find out an alternative to check this without using create file API.
