Changing Window Title To Random String - Meterpreter - Mar 7, 2016

How would I go about changing a Win32 Window Title to a random string? I have a basic idea just wondering how it would be structured and written.

Here is my random string generation:

Code 
void gen_random(char *s, const int len) {

    static const char alphanum[] =

        "0123456789"

        "ABCDEFGHIJKLMNOPQRSTUVWXYZ"

        "abcdefghijklmnopqrstuvwxyz";

    for (int i = 0; i < len; ++i) {

        s[i] = alphanum[rand() % (sizeof(alphanum) - 1)];

    }

    s[len] = 0;

}

SetWindowTextW(FindWindowW(0,L"MyCurrentWindowTitle"),L"New Title");

In C# you can do:

Code 
public static string GetUniqueKey(int maxSize)

        {

            char[] chars = new char[62];

            chars =

            "abcdefghijklmnopqrstuvwxyzåäöABCDEFGHIJKLMNOPQRSTUVWXYZÅÄÖ1234567890АаБбВвГгДдЕеӘәЖжЗзИиЙйКкЛлМмНнОоÖöПпПпрСсТтуФфХхҺһҺһЧч'ШшьЭэԚԜԝ".ToCharArray();

            byte[] data = new byte[1];

            RNGCryptoServiceProvider crypto = new RNGCryptoServiceProvider();

            crypto.GetNonZeroBytes(data);

            data = new byte[maxSize];

            crypto.GetNonZeroBytes(data);

            StringBuilder result = new StringBuilder(maxSize);

            foreach (byte b in data)

            {

                result.Append(chars[b % (chars.Length)]);

            }

            return result.ToString();

        }

Then to change the current form's name you can do:

Code 
this.Text = GetUniqueKey(15);

Of course you need:
using System.Security.Cryptography;

Hope I helped

Not blaming you at all. Sick of seeing C# stuff in this board.

OP: Take the banned guy's advice.

SetWindowText is what you're looking for.
