Frage bzgl. Combo Boxen

[Nilemet]

Hallo,

Hab gerade mit Windows 32 Programmierung angefangen.
Kann man wie in VBA festlegen, dass der User nur Einträge aus der Datenliste von der Kombobox eingeben kann?

Danke

Schaue Dir mal die Eigenschaft Style der Combobox an.

Hast du die Möglichkeiten mal durchprobiert?

es gibt nur:

CBS_AUTOHSCROLL
Automatically scrolls the text in an edit control to the right when the user types a character at the end of the line. If this style is not set, only text that fits within the rectangular boundary is allowed.

CBS_DISABLENOSCROLL
Shows a disabled vertical scroll bar in the list box when the box does not contain enough items to scroll. Without this style, the scroll bar is hidden when the list box does not contain enough items.

CBS_DROPDOWN
Similar to CBS_SIMPLE, except that the list box is not displayed unless the user selects an icon next to the edit control.

CBS_DROPDOWNLIST
Similar to CBS_DROPDOWN, except that the edit control is replaced by a static text item that displays the current selection in the list box.

CBS_HASSTRINGS
Specifies that an owner-drawn combo box contains items consisting of strings. The combo box maintains the memory and address for the strings so the application can use the CB_GETLBTEXT message to retrieve the text for a particular item.

CBS_LOWERCASE
Converts to lowercase all text in both the selection field and the list.

CBS_NOINTEGRALHEIGHT
Specifies that the size of the combo box is exactly the size specified by the application when it created the combo box. Normally, the system sizes a combo box so that it does not display partial items.

CBS_OEMCONVERT
Converts text entered in the combo box edit control from the Windows character set to the OEM character set and then back to the Windows character set. This ensures proper character conversion when the application calls the CharToOem function to convert a Windows string in the combo box to OEM characters. This style is most useful for combo boxes that contain file names and applies only to combo boxes created with the CBS_SIMPLE or CBS_DROPDOWN style.

CBS_OWNERDRAWFIXED
Specifies that the owner of the list box is responsible for drawing its contents and that the items in the list box are all the same height. The owner window receives a WM_MEASUREITEM message when the combo box is created and a WM_DRAWITEM message when a visual aspect of the combo box has changed.

CBS_OWNERDRAWVARIABLE
Specifies that the owner of the list box is responsible for drawing its contents and that the items in the list box are variable in height. The owner window receives a WM_MEASUREITEM message for each item in the combo box when you create the combo box and a WM_DRAWITEM message when a visual aspect of the combo box has changed.

CBS_SIMPLE
Displays the list box at all times. The current selection in the list box is displayed in the edit control.

CBS_SORT
Automatically sorts strings added to the list box.

CBS_UPPERCASE
Converts to uppercase all text in both the selection field and the list.

Ups, jetzt klingt es. Es geht ja gar nicht um VBA... Schaue Dir mal CBS_DROPDOWNLIST , dass sollte das korrespondierende sein.
