AutoHotkey Community

A thousand thank yous, corrupt. The solution and project files you provided easily upgraded to VC++ 2008 Express Edition (Beta 2) with no errors.

AutoHotkey builds well on VC08 Express with Vista SDK, all you need to do:

1. Do Visual Studio upgrade wizard (choose No for backup)
2. Change Debug to Release
3. Right click AutoHotkey project then Properties
4. Under C/C++ change Treat Warnings As Errors to No
5. In Linker > Input remove "LibCMT;" from Ignore Specific Library
6. Press F7 to build

I noticed a performance improvement when AutoHotkey was build this way and left uncompressed - as much as 30% faster for the most basic loop and var set test.

Forgive my ignorance, but the 30 percent improvement is being compared to what? VC++ 7 build with Vista? 2005 Express build with Vista? Thanks in advance.

Compared to the official released, which is also uncompressed.

The official release is uncompressed??

I don't think so. It probably doesn't matter, considering the EXE is decompressed (into memory) before the script starts... right?

No, I de-upx it after installation to reduce launch times.

IIRC, elsewhere in our forum, Mr.Chris quoted that a compressed exe would load faster than an uncompressed one.

It depends on cluster size, HD fragmentation etc...
It may be faster, especialy on multiple launches, to remove compression, but I doubt its noticable.

On another thread dedicated to this I posted a benchmark script with my machine spec and graphs which show that an uncompressed exe launches a lot faster, especially if it were from LZMA. I believe others like Sean do the same, but as maji said it depends on your usage (since UPX does not cache but results in shorter seeks etc.).

One thing for sure is that the MS C++ compiler has improved over the years (although GCC still owns, apparently).

Thanks for the clarifications majkinetor / Titan.

Thanks for clarifying

i succesfully compiled the source,but i can only see autohotkey.exe,autohotkeysc.bin is not there,any hints?

You need the script compiler source.

hi,

thanks for your reply.

i have the script compiler source too and it compiled ok too,but the files to create autohotkeysc.bin are not there,theres only ahk2exe.exe.


any other tip?


thanks
