Locating the servers available in the registry

Question:

How do I locate the application servers available in the

registry of the machine?

Answer:

Read the registry key under HKEY_CLASSES_ROOT\CLSID\* looking 

for keys that have a subkey "Borland DataBroker".  These

entries are application servers.  Here's an example that

loads application server names to a Listbox.



procedure TForm1.FormCreate(Sender: TObject);

var



uses Registry;

  I: integer;

  TempList: TStringList;

begin

  TempList := TStringList.Create;

  try

    with TRegistry.Create do

    try

      RootKey := HKEY_CLASSES_ROOT;

      if OpenKey('CLSID', False) then

        GetKeyNames(TempList);

      CloseKey;

      for I := 1 to TempList.Count - 1 do

        if KeyExists('CLSID\' + TempList[I] 

          + '\Borland DataBroker') then

        begin

          if OpenKey('CLSID\' + TempList[I] + '\ProgID', False) 

            then begin

              Listbox1.Items.Add(ReadString(''));

              CloseKey;

            end;

        end;

    finally

      Free;

    end;

  finally

    TempList.Free;

  end;

end;
