, the WM_CTLCOLOR and Ctlcolor functions are mapped in the control class. Add the WM_CTLCOLOR message response function in the main window, with a very familiar sentence:Hbrush HBR = Cdialog::onctlcolor (PDC, PWnd, nCtlColor);This sentence is based on the child window (or child control, nCtlColor to specify) whether there is a ctlcolor, to decide whether to execute the ctlcolor of the child window, you can debug the next step. In addition, csdn a good

Take static text for example to share how to modify text font, size, color, background and other parameters. Other text, controls, etc. can be modified by reference.1.
