I use this to check if a key exists.

It returns true if it does, and false if it doesn't exist.

Btw, it doesn't check for a value, just a key. But you can modify it. Instead of "return true", make it "return tmp" and check the returned value with whatever you want.

code:

---

function isreg(path) {
var reg, tmp;
  try {
  reg = new ActiveXObject("WScript.Shell");
  tmp = reg.RegRead(RegUserPath + path);
   if(tmp != "") return true;
  } catch(e) {
  return false;
  }
}

This is just a workaround, not a real solution, but it works and prevents the script from returning an error.

You can read more of try...catch...finally in the MSDN library.

Oh, genious.

Seriously people, is there a difference? Except from saving 0.00001 second and a couple of bytes, is there really a difference? No? Then, let it go.
