Lets say for example that I have a calculator program. This program has a drop down with "Multiply", and "Divide" in it. How would I retrieve which one is selected in the drop down? This is in C++ and Win32.

I still cannot figure out how to use CB_GETCURSEL. The MSDN site doesn't really help me a whole lot.


int index = (int)::SendMessage(hwnd, CB_GETCURSEL, 0, 0);

where "hwnd" is the handle to the ComboBox.

The index corresponds to whichever string is selected in your combo box.

Multiply = 0
Divide = 1

That's how you'd know which one was selected.

There's also a macro called ComboBox_GetCurSel() defined in the header <windowsx.h>, for example:

int selectedIndex = ComboBox_GetCurSel(hwndComboBox);
