I was just wondering if theres a way to make the compiled EXE's file size smaller. Is it normal for 20 lines to be 1.5mb?

All of the interpreter code is packed in there aswell, with Pro it only compiles the DLLs it needs but in DB everything is lumped in there

Actually the average size of a DBPro compiled exe is more than 1.5MB (currently)

There's a tool that allows you to use UPX to compress you exe file. I'll see if I have a link somewhere.

Here's the link

Ah, nice one. Cheers I'll look into that.

Wow! Thats the most handy tool I have for DBC. From 1.5mb to 12.6kb. Incredible, its a must for everyone! Thanks man!

yeah a must but only for DarkBasic Standard/Enhanced, for Professional it'll kill your exe, or fail to compress... sometimes you get lucky.

DarkBasic Standard/Enhanced really do benifit ALOT from it in size terms
Remember that the exe's are Interpreter + Ascii Code Size; as compiled dbp technically just makes the exe and not compile any code itself.

So if your project is 40KB in size, the exe will be 1.40MB + 40KB. The UPX compressor will alter all of that to pure machine code though, which means it'll really compress it extremely

Well the DBC compiler doesn't append the source code to the executable, it compiles it to tokens before. And UPX will not compress this area, just the regular exe.

I thought that opening ResHack and finding the data there gave you an accurate representation of what was in the EXE - did this person change all of the tokens back again in order to get it to display the code? I'm sure it was just a screen of ResHack.

Yes.

No, the tokens are appended to the exe, and thus not visible in ResHack (they're not part of the resource section).

I've noticed on the unrar site though is that it says exes made with the MAKE EXE option can be compressed, does this mean we can't compile our media into it and still get a stable compression?

[EDIT]
Didn't read the whole thing....well I guess what this utility needs now is documentation....anybody know of any?

The site offers three different things (there are more but well, these are the most important ones):
1) a snipptet showing how tp use a rar compressed file as an archive file.

2) a tool to make UPX (an exe compressor) work with DBC exes.

3) a tool to seperate compiled tokens from DB's VM/Interpreter.

You can use such tools with DBC? Now I feel like I've been ripped off with DBP. I tried using ASPack on a DBP project and it ruined it, but it would've worked had I been using DBC? Grrrr...
