, 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. Modify font, sizeThis is simple, first declare a member variable of type CFont in the Dlg class:Then add the following two lines of code to the class's initialization function, OnInitDialog ():1 // set the static text font size 2 M_editfont.createpointfont (_t (" song body ")); 3 M_static.setfont (m_editfont);2.
