Visual C++ 6.0 Undeclared Identifier Error

[vmagana]

First of all I would like to indicate that I am a newbie a programming. I am having a problem compiling a sample source code that I downloaded from microsoft. When I try to build the program I get an error that 'STORAGE_PROPER TY_QUERY' undeclared identifier. This structure is defined in the ntddstor.h file and is included. I dont understand why it does not see this structure.

OS: Windows XP, Visual C++ 6.0, latest SDK and changed the include and library directory order to have the SDK files first in the search order. Any ideas would be appreciated.

ErrorCode: c:\program files\microsoft visual studio\myprojec ts\programs that work\firstioctl \main.cpp|54|er ror C2065: 'STORAGE_PROPER TY_QUERY' : undeclared identifier|

The other declarations after STORAGE_PROPERT Y_QUERY that is PSTORAGE_ADAPTE R_DESCRIPTOR is defined in the same header file?
If it is so check whether you have to include any specific definitions for that.
Better put the the header file also here so that i can take a look at it

Thanks

Yes, those declarations are in the same "ntddstor.h " file. Except for the SCSI_PASS_THROU GH. I am having problems adding the code. I get an error that says I have to fill out the message and subject field. I attached the header file. Let me know if you have problems viewing the file. Thanks for your help.

Can you please post the code instead of attaching the file.

I have removed the attachment, I'm sorry but you may not post the code of ntddstor.h here as it is Copyright to the Microsoft Corporation, we do not allow the posting of copyright code.

If the file contains the definition (which you can check for yourself) then it is something to do with they way in which it has been included. Please post your code containing your include statements.

Sorry for the copyright code file. The include statements are listed in the code at the beginning of this thread. They are;

#include <stdio.h>
#include <windows.h>
#include <winioctl.h>
#include <ntddstor.h>

Yes, the ntddstor. h has the definition for the STORAGE_PROPERT Y_QUERY structure. I don't know of another way to include this file. Any recommendations would be appreciated.
