Combobox Problem, neues Fenster, wieder Combobox

C++ Combobox Problem Neues
Fenster wieder Combobox

Hallo, Ich habe ein ComboBox Problem womit ich mich schon
länger herumschlage.

Ich möchte eine Combobox erstellen, wenn man einen
Eintrag wählt, sollte ein Fenster erstellt werden. Soweit geht dies, jedoch
möchte ich, dass die Combobox weiterhin im Hauptfenster aktiv bleibt und dass
keine neue Combobox im neuen Fenster kommt. Ich werde später eben im neuen
Fenster ein Bitmap einsetzen.

Es ist ein Win32 Projekt mit MS Visual
Express 2010, bei Eigenschaften Projekt "nicht festgelegt".

Hier der
Code:

{

WNDCLASSEX wincl2; 

wincl.hInstance = hThisInstance; 
wincl.lpszClassName = szClassName; 
wincl.lpfnWndProc = WindowProcedure;

wincl.hIcon = LoadIcon (NULL, IDI_APPLICATION);
