Example

The following example demonstrates how to use various versions of the SetImage method in the CMFCButton class. The example is part of the New Controls sample.

 CMFCButton m_Button;


...


    // int m_iImage 
    // IDB_BTN1_32, IDB_BTN1_HOT_32, IDB_BTN1, IDB_BTN1_HOT are int macros that are #define. 
    if (m_iImage == 1) 
    {
        m_Button.SetImage((HBITMAP) NULL);
    }
    else
    {
        m_Button.SetImage(IDB_BTN1_32, IDB_BTN1_HOT_32);
    }
