how to get harddisk serial?

[cutie.monkey]

hi all,

is there any function in qt that will get the hard disk serial number as well as its mac address? thnks a lot..

[wysota]

No, there are no such functions in Qt. Use the native API.

[cutie.monkey]

thnks for the response.. can you give me any link or example on how to use the native API?

hi all,

i have here a simple code to get the hard disk serial, using a function from msdn.

heres my code:

#include <stdio.h>
#include <windows.h>
 
DWORD dwVolSerial;
BOOL bIsRetrieved;
 
int main() {
 
   bIsRetrieved = GetVolumeInformation("C:\\", NULL, NULL, &dwVolSerial, NULL, NULL, NULL, NULL);
 
 
   if (bIsRetrieved) {
      printf("Serial number of drive C is %X\n",dwVolSerial);
   } else {
      printf("Could not retrieve\n");
   }
 
   return 0;
}

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

DWORD dwVolSerial;
BOOL bIsRetrieved;

int main() {

   bIsRetrieved = GetVolumeInformation("C:\\", NULL, NULL, &dwVolSerial, NULL, NULL, NULL, NULL);


   if (bIsRetrieved) {
      printf("Serial number of drive C is %X\n",dwVolSerial);
   } else {
      printf("Could not retrieve\n");
   }
   
   return 0;
}

when i build my code an error occured..

src\main.cpp:19: error: cannot convert `const char*' to `const WCHAR*' for argument `1' to `BOOL GetVolumeInformationW(const WCHAR*, WCHAR*, DWORD, DWORD*, DWORD*, DWORD*, WCHAR*, DWORD)'

is there anybody here knows how to solve this error?
thnks

Hi, try

L"C:\\"

L"C:\\"

To copy to clipboard, switch view to plain text mode 

or

TEXT("C:\\")

TEXT("C:\\")

To copy to clipboard, switch view to plain text mode 

to convert to WCHAR.

thnks.. its working..
another question, how can I convert DWORD dwVolSerial to string?

[jpn]

QString::number()

[cutie.monkey]

DWORD dwVolSerial;
   printf("Serial number of drive C is %X\n",dwVolSerial); //returns Serial number of drive C is 5OB43BE
 
    QString::number(dwVolSerial) //returns 1353987262

DWORD dwVolSerial;
   printf("Serial number of drive C is %X\n",dwVolSerial); //returns Serial number of drive C is 5OB43BE

    QString::number(dwVolSerial) //returns 1353987262

To copy to clipboard, switch view to plain text mode 

how can i get the exact return (5OB43BE)?

[jpn]

Please take a closer look at QString::number() docs. It takes an optional second parameter.

[jbiloba]

Change the base to 16 (hex)

QString QString::number ( int n, int base = 16 )

default is decimal (10)

[cutie.monkey]

thnks. its finally working..

[lucian]

it's work for me

#include <qt_windows.h>

QString tdrive = "C:\\";
DWORD dwSerialNumber = 0;
bool ret = GetVolumeInformation((WCHAR *)tdrive.utf16(),NULL,NULL,&dwSerialNumber,NULL,NU LL,NULL,NULL);
if (ret) {
qDebug()<<"dwSerialNumber " << dwSerialNumber;
}

Waking up a four years dormant thread to provide an answer that was given a couple of times in the thread already. Some kind of record?

if you carefully read the topic, might notice that my solution is slightly different from the one proposed, see header file

[wysota]

And how does this include file change the solution? You are effectively calling the same function. I don't know what qt_windows.h is but it probably contains a #include <windows.h> line.

The above code returns the HDD serial number assigned by the OS ! Is there another function to retrieve the physical one assigned by the manufacturer ?
msdn suggests using the Windows Management Instrumentation: http://msdn.microsoft.com/en-us/libr...(v=vs.85).aspx
Any ideas how to do it without this service ?

Thanks a lot !

PS: I hope it is ok using this old post, I figured it is best than opening a new one with the same topic

From the GetVolumeInformation() docs:

This function returns the volume serial number that the operating system assigns when a hard disk is formatted. To programmatically obtain the hard disk's serial number that the manufacturer assigns, use the Windows Management Instrumentation (WMI) Win32_PhysicalMedia property SerialNumber.
