  1. Re: [RESOLVED] Webpage works in IE/FF but doesn't work in Chrome/Edge

    That nested try/catch can be avoided:

    // XMLHttpRequest code here
    }
    else if (window.ActiveXObject) {

    This is completely wrong. On what basis would you say a native code application is more secure than a properly sandboxed web application?

  5. Re: Question regarding file size output by GCC and G++

    Lots of loaded language there. gcc is fine. You are using a non-native port of GNU. The native compiler will always produce a tighter binary.
    Anyway, try UPX.

  8. Re: how to center single div element

    I use display:flex for almost everything now. It is quite versatile.


    <!DOCTYPE html>
    <html>
    <style>
    body {
    width: 100vw;
    height: 100vh;
    display: flex;
  9. Re: An observation about many of the technical forums and thread visibility.

    I remember suggesting cutting down the number of sections years ago but the list has only grown since then.

    Right now, 15" with a 2880x1800 resolution.
    Before I left Oz, I had a 27" monitor which actually had a lower resolution (2560x1440). Next one will probably be a 4k or 5k screen.
