The question describes as follows:In CxxActiveXCtrl I declare a member m_dlgMain for a dialog which was produce for display the picture and In CxxActiveXCtrl::OnCreate(LPCREATESTRUCT lpCreateStruct) function I wrote "m_dlgMain.Create(IDD_MAINDIALOG,this);",then in the dialog's OnInitDialog() procedure I use IPicture to display the specified picture,the display codes is correct,but can see nothing in the html,while move the codes to the dialog's OnDraw() it works ok,I suppose the dialog doesn't notify the control to erease the background but I've written InvalidRect(TRUE) after display.What's the matter?
