Read the wmic or GUID

(1/4) > >>

patrocle:
Hello all coders,

I'm trying to add a way to read wmic or GUID and then use it as a string like that http://prntscr.com/nhk98b
The goal is to identify players using multiple accounts.

I found a sample but i can't compile it, i need some lib :(


--- Code: --- FILE*  CommandResult = _popen("wmic csproduct get uuid", "rt"); //send the command to the cmd and return a pointer to the command result
char   line[256]; //a buffer to read from the file
while(fgets(line, 256, CommandResult)) printf(line); //read and print all lines one by one
_pclose(CommandResult);
--- End code ---

Can someone help me with a working  CB sample? Please

Although this is not related to C::B, I`ll try directing you to an answer.
If I get your problem right, you need to ensure only one instance of your app is running on the target machine. This is how it`s done.

Bear in mind though that this is not in any way a panacea, for sophicticated players may use additional PCs, virtual machines, diassemblers, and lots of other cool things to overcome the restriction you are trying to impose.

Thank you for the reply!

No, its only about a UUID , nothing to do with multiple instances. About "virtual machines, diassemblers, and lots of other cool things" is fine, i don't have hackers players.

A sample will really help.

Okay, digging a little bit further into your code snippet I realized that your task is to uniquely identify a Windows PC.
You could`ve stated that earlier =)

Well, getting a unique Windows installation GUID can be done as follows:


--- Code: ---HKEY hKey;
WCHAR *MachineGUID[128];
DWORD dwBufferSize = sizeof(MachineGUID);
ULONG nError;

RegOpenKeyExW(HKEY_LOCAL_MACHINE, L"SOFTWARE\\Microsoft\\Cryptography", 0, KEY_READ, &hKey);
nError = RegQueryValueExW(hKey, L"MachineGuid", 0, NULL, (LPBYTE)MachineGUID, &dwBufferSize);
RegCloseKey(hkey);

if (nError == ERROR_SUCCESS) {

   /// do something with MachineGUID...

}
--- End code ---

thanks again, compiled!

now, how could i have a string with uuid?
somthing like that:

--- Code: ---string GetUUID()
{
HKEY hKey;
WCHAR *MachineGUID[128];
DWORD dwBufferSize = sizeof(MachineGUID);
ULONG nError;

RegOpenKeyExW(HKEY_LOCAL_MACHINE, L"SOFTWARE\\Microsoft\\Cryptography", 0, KEY_READ, &hKey);
nError = RegQueryValueExW(hKey, L"MachineGuid", 0, NULL, (LPBYTE)MachineGUID, &dwBufferSize);
RegCloseKey(hKey);

if (nError == ERROR_SUCCESS) {

       //do something with MachineGUID...
       //return hKey;
}

}


// here i will use the uuid
m_RemoteSocket->PutBytes( m_GPSProtocol->SEND_GPSC_INIT3( 2, GetUUID() ) ); // verify the  uuid


--- End code ---
