How to create a singe .exe w/o other files

When I am writing an application that uses the 'implemented' components (the components at startup of new project), does my friend need some other files in his computer if I upload the .exe to him?

Question in brief:
Is it possible to have a single executable that contains all needed?
So that no "File xxxxx.dll not found!" - errors are displayed.

My program runs great on machines with VB6 but not without it.

If no extra components. It should work fine for him..

OK,

If I use extra components like MSComm, I must copy the MSCOMM32.OCX to my friend too?

Is it possible to configure the compiler or something to include it inside the .exe?

You should look for creating Packages(Setups). There are P&W, INNO etc.. Search in the Forum, you will find few tutotials on how to work with them. It will create one setup file, including all dependencies. Check out Instalations / Documentation (http://www.visualbasicforum.com/forumdisplay.php?s=&forumid=41) .

If you absolutely need a single EXE then you could look at Fusion by BitArts (www.bit-arts.com)
