,
hab es endlich geschafft. mein cedit kontroll mit nem button das jetzt ne folderauswahl aufruft und danach den pfad im cedit feld schreibt... im nachhinein frag ich mich nur - warun das so lange gedauert hatte bei mir.. es ist eigentlich ganz einfach... Habe auch gleich alles so gemacht das ich die visual styles von XP benutzen kann... das ganze besteht nun aus einer CXPBUTTON Klasse und ner CXPFolderEdit Klasse... beide gut gewürfelt und gezähmt ergeben mein CEditfeld mit browser button für Verzeichnisse... Und das schöne daran ist, dass ich die CXPButton klasse für alle Buttons verwenden kann...
Danke an alle die mir dabei geholfen haben...
Hier nun der Quellcode für alle die es Interessiert:

das einbinden funkioniert eigentlich ziemlich einfach... man erstellt ein edit feld in der Dialog ansicht... danach erstellt man eine Membervariable als control für CXPFolderEdit... der rest sollte selbsterklärend aus dem Code oben folgen - (in m_Button.SetIcon(IDI_Ordner2, 11, 11) den entsprechenden Iconcode eingeben... Für Buttons gilt eigentlich das gleiche...
- Membervariable als control für CXPBUTTON anlegen und mit memberv.SetIcon(...) das Icon festlegen... (muss aber nicht)...
falls jemand fehler oder verbesserungen findet würde ich mich freuen wenn ihr mir bescheid sagt... Bis denni... bin jetzt glaube tot müde...
