We are getting an error of the type CallbackFS.ECBFSError while mounting the CallbackFS virtual drive in our application. The error message reads as 'Overlapped I/O operation is in progress'. Can anybody guide us as to what the problem could be ?

Please give us more information about the problem - type of CallbackFS api you are using (.NET1.1, .NET2.0, Delphi or C++), a code chunk that causes the problem, Windows version, etc.

We are using CallbackFS (ver.2.0.34) API in a .NET 3.0 application on Windows 2003 machine. Here is a extract of the error message we are getting:

Message: HandlingInstanceID: 6f0247b5-df2b-4874-a579-e2b8c104dfbd
An exception of type 'CallbackFS.ECBFSError' occurred and was caught.

NativeErrorCode : 997
ErrorCode : -2147467259

We are mapping a folder called 'Test' on the D: of our machine(D:\Test). We could see that the Callback FS driver and helper dlls are loaded successfully but the code fails while invoking the method CreateStorage().

Could you give us some test application on which the bug occurs? Or at least specify a code chunk that causes the problem.
