Hardware ID Extractor DLL for Delphi/Pascal programmers
Source code examples

Hardware unique ID extractor



free software







This DLL is for Delphi/Pascal programmers (HardwareIDExtractorPas.DLL)

Delphi users can retrieve the hardware ID (for example CPU ID) with a single line of code like this: ShowMessage('CPU ID is: '+ GetCpuID)


Non-Delphi programmers (.Net, Visual Basic,Visual Fox Pro, Libert Basic, etc) read here.

Minimal source code demo for Delphi/Lazarus/Free Pascal programmers


In DPR file:
  Uses FastShareMem; 

In PAS file:
          function CPUFamily: String; external 'HardwareIDExtractorPas.DLL';
          procedure Button1ClickExecute(Sender: TObject);
          Label1.Caption:= CPUFamily;

The following functions are freely accessible (you don't need a to purchase the DLL in order to use them):

  • ChangeByteOrder
  • IntToBin
  • CoreNumber2CoreMask
  • WindowsProductID
  • GetPageSize
  • GetMemGranularity
  • GetLowAddr
  • GetHiAddr
  • SystemMemStatus
  • ProcessCurrentMem
  • ProcessPeakMem
  • IsCPUIDAvailable
  • GetCPUSpeed
  • GetCPUCount
  • IsIntel64BitCPU
  • GetDllVersion
  • ReleaseMemory  

IMPORTANT: Delphi users MUST add the FastShareMem unit to your 'uses' clause in the DPR file. The unit must be the first one listed. FastShareMem replaces Borland's ShareMem.DLL which is very good because don't have to deliver also Borland's ShareMem.DLL with your application. See the examples provided for details.
