Without MFC
int nCurSel = (int)SendMessage(hWndComboBox, CB_GETCURSEL, 0, 0);
will give the Currently Selected Item.
or
char szText[255];
GetWindowText(hWndComboBox,szText,255);
Hope it helps

It is better to use SendMessage(hWndComboBox, CB_GETLBTEXT, nCurSel, (LPARAM) (LPCSTR) szText) instead GetWindowText.

If i rememeber good, GetWindowText won't returns text oly if you're using editable combo box,
it won;t return you selection in droplist combobox

I use GetWindowText() for all three styles.

This windows message is used for a combo box. If you have multiple choice what you expected to get, and GetWindowText copies the text specified window's title bar, but if you have a window control, the text of the control is copied but you never be sure which text will be copied.

Which is what the OP was inquiring about.

You can't have multiple choices with a combobox.

This makes no sense. How could you not be sure what text will be retrieved?

Yes, you are right I am thinking about list box but in MSDN about potential message-map:
ON_CBN_SELCHANGE The selection in the list box of a combo box is about to be changed as a result of the user either clicking in the list box or changing the selection by using the arrow keys. When processing this message, the text in the edit control of the combo box can only be retrieved via GetLBText or another similar function. GetWindowText cannot be used.

Wrong. The CBN_SELCHANGE message is sent after the selection has changed.

Wrong again. GetWindowText() can most certainly be used at this point, as the combobox has already been updated to reflect the new selection.

says this :

When processing this message, the text in the edit control of the combo box can only be retrieved via GetLBText or another similar function. GetWindowText cannot be used.

That's all well and good, but MSDN is not always correct. Reality dictates that GetWindowText() can be used, and is what I always use in response to the CBN_SELCHANGE message. Go ahead, give it a try.
BTW, the link you meant to specify is here.

Are you wanting the index of the selected item, or the value of the selected item? In other words, if your listbox contained the following items:
Apple
Orange <<-- selected item
Kiwi The index of the selected item would be 1, while the value of the selected item would be Orange.

Hi all,
How should I show up a splashscreen while my application init ?
I am using MFC application wizard to create it(dialog based)
Thanks

Search MSDN for an October 1999 article by Paul DiLascia. It has a good splash screen implementation.

I tried to include a CSplitterWnd in a CFormView, but CFormView does not has OnCreateClient, so I used OnCreate, and created a static CSplitterWnd.
CSplitterWnd mSplit; //inside the class derived from CFormView
//inside OnCreate
mSplit.CreateStatic(this, 1, 2);
mSplit.CreateView(0, 0, RUNTIME_CLASS(CEditView), CSize(150, 100), NULL);
mSplit.CreateView(0, 1, RUNTIME_CLASS(CEditView), CSize(150, 100), NULL);
but there is nothing in the CFormView. Sometimes it causes an assertion when I call MoveWindow on mSplit!!! Any help in implementing it in CFormView?
I also tried creating a CFrameWnd in CFormView, and then making the parent of mSplit as CFrameWnd, but still, nothing showed up. However, when I call MoveWindow in OnSize, the application crashed, but the splitters showed up!!!!
please help, dear gurus! thanks in advanced...
