To ask about the help timovjl it is already awkward, but a problem much more above level of my knowledge.
Buttons in StatusBar are, they are pressed and pushed out, but ANYTHING more don't do.
On the Internet and in textbooks almost all examples for StatusBar show only as in it to place the text.
Has found 2 examples which place in StatusBar EditBox and ComboBox.
But these examples again on C ++ they create the classes.
Examples MSDN:

Has checked up the most different variants for reception of messages from the created buttons - they don't work.
At me such impression that the program doesn't receive ANYTHING from these buttons.
To dispel doubts, I have moved these buttons from StatusBar in Clien-area of main window. And then all these buttons began to work.
But to allocate for them space in the main window it is impossible - the empty seat isn't present. Therefore all xxxx-CAD systems use for them StatusBar (it practically the standard).

In func. WndProc() case WM_NOTIFY call CALLBACK WndStatusBar() and I see my debug MessageBox() - NOT more.

Buttons and MessageBox "the button SNAP is clicked." not works (!?)
