Hi Luigi. I am trying to compile one of your proof of concepts and Im using Visual C++ Express Addition and I can't get it to compile It just comes back with tons of errors. Any help would be appreciated.

you could have some problems using that compiler (here I use mingw/gcc), anyway the first thing you must try is what is written here:

http://aluigi.altervista.org/about.htm#compile

if you are lucky everything will compile perfectly and at least you will have less errors on which working or to post here

btw i tried mingw before with same options .. but still got some errors. i will post what i did and what i got later..

did quick test with flashchatz...
thats what i got..i think somethings wrong with my win settings ?

add the following to the gcc command-line and it will work:

mydownlib.c stristr.o -lz

this thing really starts to annoy me ... and you probably rolling your eyes by now lol.
now i remember where it started .. i was trying to compile netcat. ..it gave me similiar errors.
hope you can help me out ...

you have left -lws2_32 out

no i did not .. its after the flashchatz.c .. -lws2_32 .. right there.
its on the screenie :O
i did other test too ..

ok try to substituite stristr.o with stristr.c (the original source file).

That error is very strange, I have searched on internet and the only most interesting page (only few were found) is the following:

For the next times instead of posting the image you can simply copy and paste the content of the console window using [quote] paste_here [/quote] in the message (remember to remote "Disable BBCode in this post" in the Options of the message)

thanks for that, it compiled now...
i did...

..but when i try to run flashchatz .. it says ''this app has failed to start because zlib1.dll was not found. re-installing the app may fix this problem''
oviously something went wrong .. cuz it doesnt need any dll, right ?

edit:
file size is also not same. its 46.4kb but it should be 47.0kb

edit again:
it also compiles with ''flashchatz'' instead of ''flashchatz.exe''

update:
very wierd...i downloaded ''zlib1.dll'' and put it into the /bin folder (where the .exe is atm) and it works...but its NOT the same as the one you compiled.

About zlib1.dll it's all normal, in short exist two ways to implement libraries:

- statically, the library is included directly in the executable.
pro: portability and usage
con: you must recompile the whole stuff if a new version of the library is released

- dynamically as shared library, the classical dll
pro: smaller size of the executable and avoids redundant code (100 programs which use zlib as static have the same code repeated 100 times, while in shared more only one time)
con: you must be sure that the other people have the needed dll and in some cases just a specific version of the dll

I prefer the static mode for my tools so the people which use the included pre-compiled executable don't need to bore finding additional stuff and I don't need to included (for example) zlib1.dll in all my packages which use zlib.

If you watch in your mingw\lib directory you will find some *libz* files.
Try to leave there only libz.a and rename or place in a temporary folder all the others *libz*.

If you want smaller executables add -s to gcc

thanks. now it works.
i removed ''libz.dll.a'' (only other libz file) from the /lib folder.
now i have only ''libz.a'' in the /lib folder and it compiles well. program works without any .dll files
