Question
Accessing a MFC combo box
Hi,
1. how do I get the pointer/reference of a combo box object that I added in the MS VS 2003 GUI editor and that has got the ID "IDC_COMBO1"?
2. how do put some static strings into it's list?
3. how do I restrict the combo box to allow only the strings from the list (no manual typing)?
BTW, I'm a absolutely new to MFC and win32 but have got some C++ expirience.
Thank you for efforts.

Thank you, adding items works fine now.
But the drop down list height seems to be zero, it is appears only a thick black line. I can browse the items with the cursor keys but how do I resize the list box height to a reasonable height? Can I set set it to resize automatically somehow?
BTW, I get is the same behaviour with AddString and when I type the strings into data properties field.
About the control height, it is a common error:
Comboboxes have 2 height: Edit portion height and drop-down list height. You have not resized the second.
Go to dialog GUI editor, select your combobox, the bounding rectangle will be selected, now press on the drop-down arrow, a diferent rectangle will be selected, drag lower boundary to desired size. That's all.

go to ClassWizard (Ctrl-W)
select your dialog object
select the "member variables" tab
your control label will appear, select it
press the "Add variable" button, another dialog will appear
here is the trick: write a variable name and in the "category" choose "control"
now your dialog has a proper initialized member you can use to pass any message
