回答1：

SendMessage 是 API 函数吧

都是些定义的常数

&H 不是 16进制数

CWindow::SendMessage
LRESULT SendMessage( UINT message, WPARAM wParam = 0, LPARAM lParam = 0 );

static LRESULT SendMessage( HWND hWnd, UINT message, WPARAM wParam, LPARAM lParam )

SeeSendMessage in the Win32 SDK.

Remarks

Sends a message to the window and does not return until the window procedure has processed the message.
