The static HWND COMBO=CreateWindowW (L "COMBOBOX," L ", "WS_CHILD | WS_VISIBLE | CBS_SIMPLE, 100100200200, MHWND, (HMENU) 123456, hInst, NULL);
.
Case CBN_SELENDOK:
Int ClickedIndex; ClickedIndex=SendMessageW (COMBO, CB_GETCURSEL, (WPARAM) NULL, (LPARAM) NULL);
.
But the SendMessage function always return CB_ERR item (1) rather than being click index values, how can such a pit?

Personal think the way the SDK pure API writing Windows programs have been out of date, efficiency is too low, it is ok to understand the principle, main is message mechanism,A graphical user interface (GUI) programming can learn c + + Builder, advanced architecture (and c # drag controls), introduction to more easily,
C + + Builder is a real visual Development tool, c + + Builder can use the mouse to drag controls followed by a "design" set properties of a graphical user interface of the program, using the visual components/controls like "building blocks", built in the form of "wysiwyg" Application interface, which is the name of c + + Builder in the concept of the Builder, in this way, only needs to be written in c + + language business logic code, similar to the text interface programming under DOS, just concentrate on the business logic function, the code is very concise, data input and performance, in a graphical user interface, intuitive, and easy to use, this is RAD (Rapid Application Development, Rapid Application Development),
Book recommendation:
"C + + Builder 6 program design course (second edition)" (such as loyal lu, wen-liang liu/2011-04-01/science press) (dangdang)
"C + + Builder 6 programming examples of fine solution" (Zhao Mingxian), PDF, is a digital version, a scan version, there is also a complete implementation of tetris game,
"Wonderful" c + + Builder 6 programming Wu Yixian (Taiwan), there are a few simple little game, 10 can read later rewrite, is their mastery of the,
"C + + Builder 5 senior programming examples of fine solution" (written by Liu Bin) are larger practical program,
