Ok, before you all post criticism such as "this has been done before", I was reluctant to post this topic, but people were asking me for the source, so I posted it. May I make a few things clear before I show the source.

1. This source is largely uncommented. I wasn't expecting to release it
2. Please, if you make something with this, give me credit. The readme in the ZIP applies to the DLL and it's source.
3. Please do not copy this and turn it into a DLL and then have the audacity to claim it as your own.

Credits: cdm319 (me), Roach (for teaching me C++), Porfirio (for helping me with C++ when I started)

Source:

#define export extern "C" __declspec (dllexport) // contained in header file, but so you know how to export
#include "dll.h" // this is replaced by your default dll header file, which includes the above code
#include "windows.h"

I dont care if no-one posts here, your brilliant.

[uuf6429]

Unforetunately, I would have used this if Delphi doesn't have much simpler functions for getting this info .
Still, great work when considering it's in c/c++.

[cdm319]

These functions are easy enough uuf6429... But thanks for the replies.

[flea rowen]

thank's a lot...this is what i was searching...but...what are the total page file and the page file free?? thanks...

[Bram Buurlage]

@ flea rowen: page file is the region of your harddisk that is used as if it where ram.

@ cdm319
i got a linker error when i compile ( i use dev-cpp )
you know how to fix that?

the error:
[Linker error] undefined reference to `WinMain@16'
ld returned 1 exit status

edit: lol i fixed it myself, by putting it into a project

I would advise using my "System Information" DLL instead, as it has more functions.

Bram Buurlage
Thanks.

Everyone
Please do not bump this topic up, it is basically useless now.

[flea rowen]

i have tried it but it gave me same strange error...for example it change me a variable....may be because i use a variable named global.user but this dll is perfect for what i need...

[cdm319]

flea rowen
global.user is already used. My SystemInfo DLL is perfect for what you need. Now please, do not bump this topic any more. PM me if you have further questions.
