Probleme mit Windows-GUI mit dem Öffnen von Dateien

Ich habe den Auftrag bekommen, bei einem WIndows Server 2003 Englisch eine DHCP-Konfigurationsdatei von einem deutschen Windows 2000-DHCP-Server zu importieren.
Leider treten dabei Fehler auf. Entweder importiert der Rechner garnicht- oder es fehlt das "Optionvalue 43".
Es gibt nun die Möglichkeit, eine bestehende WIn2k3-DHCP-Konfigurationsdatei mit den Informationen des Win2K-DHCPs zu füttern.

Dazu wollte ich ein C++ Programm in "Visual C++ Express 2008" schreiben, was diese Aufgabe erfüllt. Leider habe ich bisher nur Erfahrung mit C++ in der Konsole.
Das Erstellen der GUI hat gut funktioniert.

So sieht sie aus:

Nun möchte ich gerne, dass wenn ich auf das erste "Durchsuchen" klicke ein Kontextmenü geöffnet wird, mit dem Dateien geöffnet werden können.
Ich habe dazu: hxxp:msdn.microsoft.com/de-de/library/61097ykx(VS.80).aspx zur Hilfe genommen.

Jedoch gibt mein Programm Fehler aus und lässt sich nicht kompilieren.
Die Fehler sind:

Ich habe das Beispiel von Microsoft noch nicht abgeändert, also nicht wundern.
