A transparent CSTATIC control [original]

A transparent CSTATIC control [Original] If we call a background-based dialog box, the Static control is not transparent to it. The improvement method is very simple, derived from the MFC CSTATIC, the following is the corresponding code: (Modify the control ID as other value, do not use IDC_STATIC, otherwise the variable for DDX)
