how to correct the errors?

Hi guys,

I need your help. I am using managed c++ and I have no idea how to correct the errors I have received on my error list.


Here it's the error with the each line of the code:

private: System::Void Button1_Click(System::Object^ sender, System::EventArgs^ e) {
       String ^six = "6.";
       array<String^> ^a = ProxyAddress->Text->Split('.');

       if (six = a->Length < 2 || String::IsNullOrEmpty(a[2]))
       {
         MessageBox::Show("strings found");
       }
       else if (! (a->Length < 2) || String::IsNullOrEmpty(a[2]))
       {
         MessageBox::Show("strings not found");
       }
     }



Errors: error C2440: '=' : cannot convert from 'bool' to 'System::String ^' <----- the error are highlighting on if six statement.

For the first error, you have used '=', the assignment operator, when I assume you want '==' the comparison operator. So instead of comparing six to a->Length, it is trying to assign something to six.

Thanks for your help Xander314, I have added the '==' in the used assignment operator in the first error that you have pointed out. However, what do you mean by instead of comparing six to a->Length, it is trying to assign something to six?

And could you also please help me with the errors as I have got on above and please could you also help me with this?

Basically, I was pointing out the difference between:
1
2
 
a = b; // assign b to a
a == b; // compare a and b


Before you had used the assignment operator, which was the problem, I belive.

As for many of your other problems, I'm sorry but I have never used managed C++. The first problem was just standard C++ syntax, but I'm not sure about a lot of the other stuff here. Hopefully someone else around here has more of an idea about managed C++.

Sorry :(

I have added the reference of system::Windows::Forms and the header in a class, but it doesn't help to solve it.

I have include the form1.h file in a class, but I keep getting the same errors. It is the same for this:

myform ->ShowDialog(this);
}



And it is the same that it goes for this:

e->Cancel = true;
}

Any idea how to solve them?

Maybe you could look for a C++/CLI forum.
