Re: Ways to get a Computers "ID"

I have found a link:
http://www.codeguru.com/forum/showthread.php?t=249788

I think I will go for checking the BIOS SerialNumber. In the link it seems to fail when doing this on Windows 98 or earlier but if a fail meens an emty string like: "" that will work for my purpose.

They refer to get the BIOS Serial like below but when gooling on that, I am not sure if I can find anything helpful of how to return this serial number.
I use VC++ 2008 Express Edition

C++ Syntax (Toggle Plain Text)
GetBIOSSerial(); //Is this a call,  I cant find out if any namespace goes with this
GetBIOSSerial(); //Is this a call,  I cant find out if any namespace goes with this

Re: Ways to get a Computers "ID"

I have come up with a code that look like this that is supposed to return the motherboard serialnumber.
The number that is returned is: "123456789000"

I wonder if that really could be correct or perheps do I miss something in the code. I am looking for a unique serial number ?

C++ Syntax (Toggle Plain Text)
ManagementObjectSearcher ^searcher;  
ManagementObjectCollection::ManagementObjectEnumerator ^queryEnum;  
ManagementBaseObject ^objMgmt;  
 
searcher = gcnew ManagementObjectSearcher("SELECT * FROM Win32_Baseboard");  
 
ManagementObjectCollection ^queryCollection = searcher->Get();            
 
queryEnum = queryCollection->GetEnumerator();  
 
while(queryEnum->MoveNext())
{  
    objMgmt = queryEnum->Current;  
    MessageBox::Show(Convert::ToString(objMgmt->GetPropertyValue("SerialNumber")));  
}
ManagementObjectSearcher ^searcher;  
ManagementObjectCollection::ManagementObjectEnumerator ^queryEnum;  
ManagementBaseObject ^objMgmt;  
  
searcher = gcnew ManagementObjectSearcher("SELECT * FROM Win32_Baseboard");  
  
ManagementObjectCollection ^queryCollection = searcher->Get();            
              
queryEnum = queryCollection->GetEnumerator();  
  
while(queryEnum->MoveNext())
{  
    objMgmt = queryEnum->Current;  
    MessageBox::Show(Convert::ToString(objMgmt->GetPropertyValue("SerialNumber")));  
}

If you post the complete program (or some test code) then we can test it on our computers to see what it returns.

Re: Ways to get a Computers "ID"

Yes, that would be more than nice.
I think this would be the complete testcode if I dont miss anything out.

I think this would be the complete testcode and see what this MessageBox returns.
You would have to add the reference System::Management in "Add New Reference"

using namespace System::Management;

C++ Syntax (Toggle Plain Text)
ManagementObjectSearcher ^searcher;  
ManagementObjectCollection::ManagementObjectEnumerator ^queryEnum;  
ManagementBaseObject ^objMgmt;  
 
searcher = gcnew ManagementObjectSearcher("SELECT * FROM Win32_Baseboard");  
 
ManagementObjectCollection ^queryCollection = searcher->Get();            
 
queryEnum = queryCollection->GetEnumerator();  
 
while(queryEnum->MoveNext())
{  
    objMgmt = queryEnum->Current;  
    MessageBox::Show(Convert::ToString(objMgmt->GetPropertyValue("SerialNumber")));  
}
ManagementObjectSearcher ^searcher;  
ManagementObjectCollection::ManagementObjectEnumerator ^queryEnum;  
ManagementBaseObject ^objMgmt;  
  
searcher = gcnew ManagementObjectSearcher("SELECT * FROM Win32_Baseboard");  
  
ManagementObjectCollection ^queryCollection = searcher->Get();            
              
queryEnum = queryCollection->GetEnumerator();  
  
while(queryEnum->MoveNext())
{  
    objMgmt = queryEnum->Current;  
    MessageBox::Show(Convert::ToString(objMgmt->GetPropertyValue("SerialNumber")));  
}

Re: Ways to get a Computers "ID"

The part I replace most often: is the motherboard(usually in conjunction with PSU). Those thing short out all the time, and now I have piles of them!

So be wary about how you use that. The only reason I can find, to use it is to block suspected bots off something like a MMORPG for a few hours, till the lag drops.

Re: Ways to get a Computers "ID"

This is true, I am checking for possibilities and in the end, I will be that careful to see what can be possible or it wont be, how to define things etc...
