Retrieving information from SMBIOS

[Edgar Akhmadeev]

Written code to read hardware information (motherboard and platform) from SMBIOS. WinAPI is used, of course. Can be used to bind products to hardware. In my opinion, it makes no sense to bind to anything other than the motherboard. Drives, video cards are variable.

Put SMBIOS.mqh in Include.

Test SMBIOS.mq5 - in Scripts.

For real use, when you don't need unnecessary information, comment it out / don't define #define SMBIOS_DEBUG

I've only tested it on one laptop and VPS and it needs community checking and reporting if it's not working correctly. Check the data against the hwinfo program.

1. The code makes the assumption that data from SMBIOS is output in a fixed order. Soif there are inconsistencies, it is advisable to give a full test output and screenshots from hwinfo from the BIOS, System, Mainboard and System enclosure tabs from the Motherboard/SMBIOS DMI tree. Otherwise I will not be able to debug.

2. Need some advice from handset programmers on how to make it look nice here:

//const uint    SMBIOS_signature = 'RSMB';
const uint      SMBIOS_signature = ('R' << 24) + ('S' << 16) + ('M' << 8) + 'B';

Seems to be giving out a different number of fields. Tried to make an array with a margin and see if it moves out. Reposted SMBIOS.mqh.

PS: like I said, only tested on one computer. No access to the others. So don't be sorry.

how to make it look pretty here:

template <typename T>
T StringToInteger2( const string Str )
{
  T Res = 0;
  
//  const int Size = MathMin(StringLen(Str), sizeof(T));
  const int Size = StringLen(Str);
  
  for (int i = 0; i < Size; i++)
    Res = (Res << 8) + Str[i];
    
  return(Res);
}

//const uint    SMBIOS_signature = 'RSMB';
const uint      SMBIOS_signature = StringToInteger2<uint>("RSMB");

Thank you. Beautiful, but somehow redundant. I would like it without executable code.

It worked, I need to attach it to the 4,
