In order to obtain hardware attributes in a Windows machine, it is possible to utilize the Windows Management Instrumentation command-line (WMIC). 4D has the ability to call WMIC through LAUNCH EXTERNAL PROCESS.

The sample code below can extract the following:

• Computer Product Name


• Processor ID


• Bios Serial Number


• Hard Drive Serial Number

C_TEXT($in) C_TEXT($outCPN;$outPID;$outBSN;$outHDSN) //Output of requested attribute C_TEXT($errCPN;$errPID;$errBSN;$errHDSN) //Error of Outputs $in:="" SET ENVIRONMENT VARIABLE("_4D_OPTION_HIDE_CONSOLE";"True") // hide console LAUNCH EXTERNAL PROCESS("wmic csproduct get name";$in;$outCPN;$errCPN) SET ENVIRONMENT VARIABLE("_4D_OPTION_HIDE_CONSOLE";"True") // hide console LAUNCH EXTERNAL PROCESS("wmic cpu get ProcessorId";$in;$outPID;$errPID) SET ENVIRONMENT VARIABLE("_4D_OPTION_HIDE_CONSOLE";"True") // hide console LAUNCH EXTERNAL PROCESS("wmic bios get serialnumber";$in;$outBSN;$errBSN) SET ENVIRONMENT VARIABLE("_4D_OPTION_HIDE_CONSOLE";"True") // hide console LAUNCH EXTERNAL PROCESS("wmic diskdrive get serialnumber";$in;$outHDSN;$errHDSN)

$errCPN - Extracts the Computer Product Name (eg: Name XPS 8512)
$errPID - Extracts the Processor ID (eg: ProcessorID BFEBFBFF142345B8)
$errBSN - Extracts the Bios serial number (eg: Serial Number 574ZVV1)
$errHDSN - Extracts the Hard Drive serial number (eg: Serial Number 215126043035)

Please note that WMIC has wide range of attributes to extract and the code above is just a sample.

WMIC Applies to the following Windows OS:

• Windows XP, Vista, and 7


• Windows Server 2003 and 2008
