Thread: Retrieve users connected to Access database

Can anyone help me convert the following code to C++? It's code for retrieving the active users of an Access MDB database file. Unfortunately, I cannot google any C++ examples. What totally confuses me is JET_SCHEMA_USERROSTER constant.

Thanx
Bob

Code:

const
  JET_SCHEMA_USERROSTER = '{947bb102-5d43-11d1-bdbf-00c04fb92675}';
var
  i: Integer;
  Line: String;

with ADOConnection1.OpenSchema(adSchemaProviderSpecific, EmptyParam, JET_SCHEMA_USERROSTER) do
  while not EOF do
  begin
    Line := '';
    with Fields do
      for i := 0 to Count - 1 do
      begin
        Line := Line + Item[i].Name + ':';
        if VarIsNull(Item[i].Value) then
          Line := Line + '(Null)'
        else
          Line := Line + String(Item[i].Value);
        Line := Line + #13;
      end;

    // remove zero bytes
    for i := 1 to Length(Line) do
      if Line[i] = #0 then
        Line[i] := ' ';

    ShowMessage(Line);

    MoveNext;
  end;
