By declaring it static, you've restricted the scope of that variable to the file where it is declared. You might want to look into the keyword extern (declare the variable globally without the static keyword and declare it as extern where you are trying to use it)

so in my case I should do as below
Shared.h
bool bDone;
abc.h
#include "Shared.h"
extern bDone;
xyz.h
#include "Shared.h"
extern bDone;
If I am not worng

Are you going to wait until I say "yes, go ahead"?  Why not try it in the IDE and ask queries if it didn't work?

No luck
now I got
.obj : error LNK2001: unresolved external symbol "bool m_BusyCursor"
|
|
|
|
|
do it all extern (declaration), AND "bool bDone = false;" in the Shared.cpp (instanciation)

UINT uDriveType = GetDriveType(sDriveLabel)
0 - Unknown drive

Handle WM_DEVICECHANGE message

If possible can u suggest me any sample regarding the same...

I had code to access the serial number of a hard drive. I was running this in user mode, getting a handle to the drive as follows:
HANDLE hDrive ;
wchar_t driveName[128];
for(int i = 0; i < 16; ++i)
{
wsprintf(driveName, L"\\\\.\\PhysicalDrive%d", drive);
hDrive = CreateFile(driveName, GENERIC_READ | GENERIC_WRITE, FILE_SHARE_READ | FILE_SHARE_WRITE , NULL, OPEN_EXISTING, 0, NULL);
...
}
I'm now trying to do the same thing in a driver. However I'm not sure how to open the actual drive. Currently the code I have is:
HANDLE hDrive;
WCHAR sDriveName[128];
OBJECT_ATTRIBUTES oa;
UNICODE_STRING usDriveName;
IO_STATUS_BLOCK iosb;
NTSTATUS Status = STATUS_UNSUCCESSFUL;
int drive;
for(drive = 0; drive < MAX_IDE_DRIVES; drive++)
{
_snwprintf(sDriveName, 128, L"\\Device\\Harddisk%lu", drive);
RtlInitUnicodeString(&usDriveName, sDriveName);
InitializeObjectAttributes(&oa, &usDriveName, OBJ_INHERIT, NULL, NULL);
if(NT_SUCCESS(ZwOpenFile(&hDrive, FILE_ALL_ACCESS, &oa, &iosb, FILE_SHARE_READ | FILE_SHARE_WRITE, FILE_DIRECTORY_FILE)))
{
...
}
}
However the call to ZwOpenFile is failing with iosb.Status == 3.
Any ideas what I am doing wrong here??
Thanks.

Does that equal STATUS_WAIT_3?

The return value from the call to ZwOpenFile is STATUS_OBJECT_NAME_NOT_FOUND, so I guess the issue is I have the name wrong. More investigation needed on my part.
