using more than one cpp source

its easy to include the resource file, and use multiple header files, however, i just dont understand how to use more than one source file. I was told to just make it and include it, but that didn't work out and now were both stumped.

Basically, all my projects have been one source file, DarkCode, HyperTextFX, both have over 2000 lines of code to sift through in one file, i would REALLY like to diminish this and separate into more than one source.

Could someone help me on the procedure to do this.

Thanks.

Just include a new file to the project on the project menu in msvs,
or if you´re compiling manually just add all your .cpp files on the commandline like this: cl file1.cpp file2.cpp

whats the general rule for splitting? like where would i split the source files for DOS and or Windows programming? I know for a fact that you need all the class definitions for the window in one file, but after that, i just dont understand.

Ill give that method a try when i get home today pheer. Thanks.

General rule? No, just use your common sense. Put all graphics code in one file and the soundcode in another and so on.

makes sense...

would it be at all wise to put every dialog box function in its own source? (i have like...7 at the most)

glowtext.cpp = has the entire IDD_GLOW dialog box functions, while the resource script models the way it appears
