|My main .cpp file is getting too big.
I tried to create a new file to place all new functions to the main class, but then run into compiler errors.
Are they a simple way of splitting up a large file into several smaller files and not running into the mess as to what headers to include.
I thought that Visual Studio would have managed this when I add new funtions (via the IDE) but No!
c:\My_Example\My_ExampleDlg.h(42): error C2065: 'IDD_MY_EXAMPLE_DIALOG' : undeclared identifier
But when I place all the functions into a single file all is OK.
