C++ Anagram Maker Error - c++

Question

I have been trying to make an anagram maker, using a textBox (encryption_text) for input, which the text is "Hello World", and the output textBox (encrypted_text) which receives the text:
"ellllloooo
WWWWWWooooooorrrrrrrrllllllllldddddddddd".
I also have a textBox called 'anag_used', which should record the used number/location in the string to encrypt.
Have I over complicated it, or is there an error?
Thanks :)
Here is my code:
void anagram()
{
string toanagram = marshal_as<string>(encryption_text->Text);
string out;
int k;
System::String^ rndstr;
System::String^ ktostr;
ostringstream kstr;
anag_used->Clear();
for (int i = 0; i < toanagram.size(); ++i)
{
anag_used->Text += "\n";
int rnd = 0 + rand() % toanagram.size();
ostringstream rndtostr;
rndtostr << rnd;
rndstr = gcnew System::String(rndtostr.str().c_str());
for (int l = 0; l < i; ++l)
{
if (anag_used->Lines[l] == rndstr)
{
k = rnd;
kstr << k;
ktostr = gcnew System::String(kstr.str().c_str());
for (System::String^ j = anag_used->Lines[l]; j == ktostr; k = 0 + rand() % toanagram.size())
{
kstr << k;
ktostr = gcnew System::String(kstr.str().c_str());
if (anag_used->Lines[l] == ktostr)
{
//Do someting if you want
}
else
{
out += toanagram[k];
anag_used->Lines[l] = ktostr;
}
}
}
else
{
out += toanagram[i];
anag_used->Lines[i] = rndstr;
}
}
}
encrypted_text->Text = marshal_as<System::String^>(out);
}
EDIT: FOUND A MUCH SIMPLER WORKING CODE
#include <algorithm>
.
string toanagram = marshal_as<string>(encryption_text->Text);
sort(toanagram.begin(), toanagram.end());
encrypted_text->Text = marshal_as<System::String^>(toanagram);

This works for console, but you could implement it in C++/CLI quite easily
#include <iostream>
#include <sstream>
#include <vector>
#include <ctime>
void str_vect(std::vector<const char>* v, std::string& s)
{
for (int i = 0; i < s.length(); ++i)
{
v->push_back(s[i]);
}
}
int main()
{
for (;;)
{
std::cout << "Please enter the word / phrase\n";
std::string word;
std::getline(std::cin, word);
std::vector<const char> word_split;
str_vect(&word_split, word);
int sz = word_split.size();
std::string anagram;
for (int i = 0; i < sz; ++i)
{
srand(time(NULL));
int r = (rand() % (word_split.size() - 0)) + 0;
anagram += word_split[r];
word_split.erase((word_split.begin()) + r);
}
system("cls");
std::cout << "Please guess the anagrammed phrase / word - '" << anagram << "'\n";
int max_tries = 3;
int tries = max_tries;
for (int i = 0; i <= max_tries; ++i)
{
std::string guess;
std::getline(std::cin, guess);
if (guess != word)
{
tries--;
if (tries == 0)
{
std::cout << "You have ran out of tries. The answer was: " << word << "\n";
break;
}
std::cout << tries << ((tries == 1) ? " try" : " tries") << " left\n";
}
else
{
std::cout << "Correct!\n";
break;
}
}
}
}

#include <algorithm>
.
string toanagram = marshal_as<string>(encryption_text->Text);
sort(toanagram.begin(), toanagram.end());
encrypted_text->Text = marshal_as<System::String^>(toanagram);
