decimal to binary 1

[ugly]

I have a simple dialog box containing two edit boxes, If a decimal number is entered into the first box I would like for the equivalent binary value to appear in the second box.

You could do it this way:
The "Decimal-Edit box" should get a variable type 'int',
the other type 'CString'.
When a button is clicked (or another message of your choice), do this:

void CYourDialog::OnMessage()
{
  UpdateData();
  char buffer[20]; //20 could take numbers up to 2^18(+\0)
  _itoa(decimal_variable, buffer, 2)//2 indicates binary
  strBinaryVariable= buffer;
  UpdateData(FALSE);
}

This works; but it is not a very good code.
Eg. you have to look out that the decimal value is not negative etc.
