How can I define and insert a control at runtime?

[barbacot]

I wrote the following code, but the ComboBox doesn't display. Is the same thing for any other control.

CComboBox c;
c.Create(WS_CHILD | WS_VISIBLE, CRect(10, 10, 50, 50), this, 1047);
c.ShowWindow(SW_SHOW); // this should be the default, anyway

The Create() function returns TRUE, I checked. So what is missing / wrong?

You should create CCombox instance in the heap instead of the stack, because memory is released after your CComboBox instance goes out of the function scope.
use:

CComboBox *c = new CComboBox;
