Using: WinAPI CreateFilemapping, parameter is set to: 0 * fffffff; Description it is a shared memory instead of a file.
E.g:
Mymapfile = CreateFilemapping ((Handle) (0 * ffffffff), NULL, PAGE_READWRITE, 0, 9999, "Recherfile");
IF (mymapfile! = null) mymapfile = (char *) MapViewOffile (MyMapFile, File_Map_all_access, 0,0,0);
Else ShowMessage ("mymapfile == null);
Second: Definition at the header file (.h): #iinclude wm_user_Message WM_USER 1
Definition: Message Void Wmuser (TMESSAGE MSG);
Begin_MESSAGE_MAP
Maessage_Handler (WM_USER, TMEESSAGE, WMUSER);
END_MESSAGE_MAP (TFORM);
Message Void TFORM1 :: Wmuser (TMESSAGE MSG)
{
File: // ourselves;
}
Remember to finally delete the handle (MyMapFile); CloseHandle (MyMapFile)
