Here's a piece of code written in C++ which might help you.
#include <iostream>
#include <string>
#include <fstream>
#include <time.h>

int main()
{
const std::string fileName = "path/to/file.extension";

// first, never forget to seed the number generator
// if you didn't do it already
srand ...

I solved it!
Thanks MrAksel...

CosmosUserKit, when i try to install it, it says : Visual Studio 2010 not installed!
But i have C# and VB.NET installed...
What i should do?And how i can install studio even if i have C# and VB.NET?

I want to install CosmosUserKit, but it require Visual Studio...But i have installed VB.NET and C# one by one...

Cosmos OS require VS2010 installed, but i installed C# without entire VS...What i can do?

I know...
I made a folder in D called IlMerge, i copied my program and dll in that folder.
I opened cmd, and i entered :
cd [il merge folder]
ilmerge /target:winexe /out:Out.exe D:\IlMerge\program.exe D:\IlMerge\file.dll

And appears an error...
Anyway...i will let it .dll ...

I want to include it in project, but to do not appear in debug directory.
I want to run program if it isn't there...
Now i am trying with ilmerge...

How i can compile a dll with my program?
No archive or any of this things...
Only if i can include dll in my project, and when i run program, that will load dll file from inside.
Thanks.
