In 32 and 64 bits it is forbidden (by the operating system) to directly access to memory addresses contents.

You have to use Windows API functions to access the information that you are looking for

You can use wmi to get these informations

Code: Select all  Expand view

TRY
    oWmi := CreateObject( "wbemScripting.SwbemLocator" )
  CATCH oErr
    oWmi := nil
    lError := .t.
    cError := oErr:Description
  END

  IF !lError
    objWMI:= ::oWmi:ConnectServer() // (strComputer, "root\cimv2")
  ENDIF

oBios := objWMI:ExecQuery( "Select * FROM Win32_BIOS" )

FOR EACH oData IN oBios
    cManufacturer  := oData:Manufacturer
    cName          := oData:Name
    cSerialNumber  := oData:SerialNumber
    dReleaseDate   := StoD (SubStr(oData:ReleaseDate,1,8))
    cVersion       := oData:SMBIOSBIOSVersion
    cRevison       := oData:Version
NEXT

Hi Stefan
Thanks for reply , this is going well ...
But i am still interested how to use Windows api functions (what is the way to use them)

With best regards,

[Antonio Linares]

You can read that info from the registry:

HKEY_LOCAL_MACHINE\HARDWARE\DESCRIPTION\System\

SystemBIOSDate
SystemBIOSVersion
VideoBIOSDate

Hi Antonio,
That is ok ...work fine
But i want to know how to use Windows Api functions. Not only for bios date but probably i will need to use other api functions.
i mean HOW TO CALL API FUNCTIONS ?

Regards,

[Antonio Linares]

All the source code in FWH\source\winapi\*.c are example of calls to the Windows API functions

[Antonio Linares]

Here you have an example:
