Using help from a forum called http://stackoverflow.com , I finally got the String to double and double to String
conversions going.
The CLR gui looks a lil more polished than MFC but requires .NET framework of the correct version when it runs.
The MFC that I got to work first has the String to double and double to string built into the EditText. You right mouse
and tell what double variable you want the EdtText to use.

//Here is the conversion part CLR C++ GUI
//CLR isnt too bad… better than MFC yes?
double dblInput1 = 0.0;
double dblInput2 = 0.0;
double dblAnswer = 0.0;
String ^ strInput1;
String ^ strInput2;
strInput1 = this->Input1textBox->Text;
strInput2 = this->Input2textBox->Text;
if (Double::TryParse(strInput1, dblInput1) & Double::TryParse(strInput2, dblInput2))
{
// do something
dblAnswer = dblInput1 + dblInput2;
Answer1textBox->Text = System::Convert::ToString( dblAnswer );
}
else
{
// the text was not a number
MessageBox::Show(“Error”);
}
