How to create an MFC ComboBox with search

I need a combo box in a Windows MFC application that has a search function. It should work so that if you start to enter something that matches one or more items in the list, a drop-down menu and hang out these items. Kinda as popular ajax-based search boxes on the Internet

Do you need to know any control that provides this functionality? - Is there a link to information on how to create such functionality yourself? - Any ideas on how to do this, what could you share?

The renamed class, since CComboBoxEx is now part of MFC, and added the ShowDropDown () call to OnEditUpdate ().

Provide a handler for the CBN_EDITCHANGE event, your handler will be called every time the user changes the text in the edit field.

In this handler, call the CComboBox::FindString() method to see if the entered text exists in any of your combobox entries. If so, call CComboBox::SetCurSel() to select it.

This is the Win32 api FAQ. See Adv. Win32 api ng news: //194.177.96.26/comp.os.ms-windows.programmer.win32 (you do not need CBN_EDITCHANGE at all, it is automatically with api)

Full access to the combo box edit window:

 CEdit *pEdit = (CEdit *)pComboBox->GetWindow(GW_CHILD);

CEdit * pEdit = (CEdit *) pComboBox-> GetWindow (GW_CHILD);

Is it possible to access the ListBox part in a similar way? It is necessary to clear the contents of the list, for example. using ResetContent.
