EXE to COM

Is there a way to convert an EXE to COM file (and vice versa) with C++? I only know the basics of assembly, but I am familiar with Windows and the win32 concept. I know that EXE's contain a file header, that is essentially unneeded. Also, I believe they start at a different memory locale or something to that effect. I don't know if C++ has the low-level power I am looking for.

Hi AccessT~

Sorry, I haven't messed with that sort of stuff for so long I wouldn't dare try to advise you :)

However, I did know what I was looking for:

Plenty of resource there? Even a few tools, although I would imagine most are ASM.

Cheers

Just trying to learn here: Why would you want to convert an exe to com?

Thanx,

Hi,

I don't know if a exe can be converted into .com......................com files have a Single segment..........so a com file cannot be bigger than 64 k ..............it would be quite Difficult a Exe might contain Multiple segments .

I am not Quite sure here .........

Hi Kurt~ and SwordFish.

Yes they can be converted................if you follow the link in my previous post, you will find tools and discussions.

As I recall it has something to do with creating DOS drivers for a windows environment and vice versa..............playing old games and running old/legacy applications.............as I said it is a long time ago. I only found the link because I happened to remember the name of one of the apps from way back. :)

Thanks for the replies. I have seen source for a program of this type, but it is written in ASM. I have very limited ASM knowledge...my question is: can this be done in C++?

Hi,

As I mentioned I had a brief exposure some time ago................I do not know what C++ can do, but I know that the task can be done in C, and possibly Basic. If C++ will do what can be done in C then the answer is "yes"

My point would be that this task/requirement belongs to the past, when the tools were different (there was no C++ :) ).

Try looking for a solution in C, then look to convert that to C++???????????????

I guess that is my era.

I am sorry I cannot help more, I am a lazy £$%^&* and would always use a tool, or steal code and modify it, rather than write something original..................I guess that must make me the ORIGINAL SCRIPT KIDDIE? :D

The approach allowed me more drinking time......................

Seriously though, given the era of the requirement, I feel that you will have to search for a solution in ann older language, and look to convert it.

Good luck
