cannot convert from 'const char [11]' to 'System::Windows::Forms::TextBox ^' - visual-c++

Question

I'm pretty new to c++ and i'm making a program in visual c++. Everything was going great until this error appeared:
error C2440: '==' : cannot convert from 'const char [11]' to'System::Windows::Forms::TextBox ^'
im pretty sure it has something to do with me putting numbers in the text box instead of words.
here's part of the code:
if (fnum==true){
if (phoneNum=="555555555"){ // i think this part causes the problem
//code for when the phone number is correct
} else {
//if phone number is not correct
}
}
i tried putting '5555555555' instead of "5555555555" but it gave me a different errors
error C2015: too many characters in constant
error C2446: '==' : no conversion from 'int' to 'System::Windows::Forms::TextBox ^'
heres the rest of the code:

As i said before i'm new to c++ and i don't really know much, so if you could give the answer in a simple form that would be great. like showing what to change and what it does.
thanks in advanced.

Answer 1

phoneNum is a a TextBox^, not a "string" of some form. You'll want to compare against the Text property of this control, not the control itself.
You likely need:
if (phoneNum->Text == "555555555")
{
