LoadIcon LoadImage (if you use the LR_SHARED flag) CopyImage (if you use the LR_COPYRETURNORG flag and the hImage parameter is a shared icon) CreateIconFromResource CreateIconFromResourceEx (if you use the LR_SHARED flag) Function Information Minimum DLL Versionuser32.dll HeaderDeclared in Winuser.h, include Windows.h Import libraryUser32.lib Minimum operating systemsWindows 95, Windows NT 3.1 UnicodeImplemented as Unicode version.
