I'm trying to understand how to change the background color of an edit box. I have read a number of items on this, but most are offering a prewritten class, or presume knowledge I do not yet have. So, Suppose I have a dialog (MyDlg) with one editbox (IDC_EDIT) and one button (IDC_BUTTON). I want to push the button IDC_BUTTON and make the background of edit box IDC_EDIT red. This is the simplest example I can think of, and I hope I can see the code to do this so I can use it to gain an understanding of what is involved. Thanks.
