Visual C++: displaying integer in a text Box

Question

I want to write

int i=4;
textBox1->Text = i;

But it is giving compilation error for type mismatch. How to do box or typecast this?

Answer 1

You need conversion, not a cast. Use itoa() or itow() depending on whether you compile for Unicode.

Answer 2

if you are using CString you can use Format method, or use old c function itoa

example:

CString str;
str.Format("%d",i);

also do not forget to call UpdateData method to update the GUI controls

Answer 3

Convert integer to string and set as value for Text.

CString textVal;
textVal.Format(_T("%d"), i);
textBox1->Text = textVal;

Answer 4

Sorry for answering the quesition myself. But I just got it while searching. There is a very easy method

int i=4;
textBox1->Text = Convert::ToString(i);
