Decimal string to Char string Problem in Visual C++ window form application

Good day. I am facing a problem. I am using Visual Studio C++ and wish to create a Window Form Application. The purpose to create this program is to show the encrypted text from a textbox in a small window.

Below is my code:

Code:

---

String ^ Data1;
String ^ Data2;
int key = 'x';

Data = richTextBox1 -> Text;

int iLen = richTextBox1 -> Text -> Length; //define the string length

for (int i=0 ; i < iLen ; i++)
{
Data1 += Data[i] ^ (int(key) * i + int(key) / (i+1)) % 255; //Encryption formula
}

MessageBox :: Show(Data1); //Show the encrypted text in window

---

For above, if Data din't pass the Encryption Formula, i will show the exactly TEXT in the textbox. But Data undergo the encryption formula, The DATA1 show the TEXT in decimal value.

As example:

"1" = 49
When i type "1", undergo the formula, so it must come out "I" in character form. But from my code above, it show decimal 73(decimal of char "I").

How can i make it to show "I" rather than showing 73?

Thanks in advance. Sorry for my bad English and Explanation.

Windows Forms Application is not actually C++, but another language called C++/CLI. This section is for ISO C++, not C++/CLI. In the future, it might be a good idea to post these in the teach board section. Just a FYI.

If you try to append an integer to a string, it will try to treat it as a number.

Cast the result of your math to a char before you append it to the string.
