Program is DOS aplication. On XP runs in DosBox. Without any problems. Smooth and clear :) How to make or link or compile, with what to do that the program become standalone, just one exe which be able to open DosBox or some DOS-emulation and it'll be great that all thing works in some virtual directory, folder. Something like BeOS (500MB of file). Does exist something like this? Thanx.

If you want the DOS application to start automatically just clicking the emulator's icon, that can be done by using Virtual PC from Microsof'ts site (it's free). I don't like DOSBOX and prefer true virtual machines as Virtual PC or VirtualBox even if they require an additional copy of the guest OS (that is built-in for DOSBOX). For DOS you can download for free FreeDOS, the open source MS-DOS clone, and then set up your autoexec and config file to autostart the program. To complete the self-activating process you need to code the proper switches on the command line of Virtual PC. It seems tricky, but quite easy using the on-line virtual machine help.
