 Question: 
 I want to read out the binary-value "problems" of the path 
 HKEY_DYN_DATA\Config Manager\Enum\[add the key of a hardware component] to 
 detect if a hardware component is troubled and not working right. 
 But I cannot handle the ReadBinaryData-Method of TRegistry correct. 
 Everytime I use it, it always returns "4" as content of the buffer. 
 How do I detect if the content of the binary-key "problems" is 
 not "00 00 00 00" but something else like "16 00 00 00" or such? 
} 

{Answer: Here's an example of ReadBinaryData } 

procedure TFrmReadBinary.Button1Click(Sender: TObject); 
const 
  CKeyName: string = 'System\Setup'; 
  CValName: string = 'NetcardDlls'; 
var 
  keyGood: boolean; 
  p: integer; 
  regKey: TRegistry; 
  tmpStr: string; 
  vSize: integer; 
begin 
  regKey := TRegistry.Create; 
  try 
    regKey.RootKey := HKEY_LOCAL_MACHINE; 
    keyGood  := regKey.OpenKey(CKeyName, False); 

    if (keyGood) then 
    begin 
      vSize := regKey.GetDataSize(CValName); 

      if (vSize > 0) then 
      begin 
        SetLength(tmpStr, vSize); 
        regKey.ReadBinaryData(CValName, tmpstr[1], vSize); 

        repeat 
          p := Pos(#0, tmpStr); 

          if p <> 0 then 
          begin 
            Delete(tmpStr, p, 1); 
            Insert(#13#10, tmpStr, p); 
          end; 
        until p = 0; 

        (*StringReplace(tmpStr, #0, #13#10, [rfReplaceAll]); *) 

        ListBox1.Items.Text := tmpStr; 
      end; 
    end; 
  finally 
    regKey.Free; 
  end; 
end;
