Hi, In a source code tested in BC++ the following line occurs: #include <commctrl.h> What's the use of that header file? My g++ compiler returns an error message ('No such file or directory'). What can I do about this? TIA, Serge Helfrich - For help on using this list (especially unsubscribing), send a message to "gnu-win32-request@cygnus.com" with one line of text: "help".
