• how to scan a LAN for live hosts using PHP and SNMP?

  - by aag

  I would like to have a quick script listing all active hosts in a LAN, and I am a bit lost. From other posts I figured that this can be done most effectively by polling the DHCP server (in my case a Lancom router) using SNMP. However, I am not familiar with the SNMP commands in PHP. Is snmpwalk() the correct function? Can I get snmpwalk() or any other php function to return an array that contains a list of all live hosts?

• GWT + XML documents with namespaces

  - by chris_l

  I'd like to get a quick overview of available solutions (libraries, ...) that allow me to work with XML documents with namespaces on a DOM level - in GWT's client side. Additionally, I'm looking for an XPath solution that can work on that DOM (even if it requires writing my own XPath Navigator). XML parsing and serialization isn't necessary on the client - this can be done on the server.

• Is it possible to use a string variable to reference an element in Javascript?

  - by somerandomguy

  Here's the quick version of the code as it stands right now: function foo(attributeName, someJSObj, key, newValue) { someJSObj[key].attributeName = newValue; } Obviously this doesn't work, since it just creates a new element called attributeName. Is there an easy way to dereference the attributeName into the string that represents some existing attribute on someJSObj?

• C++ operator[ ] on integer litteral

  - by gregseth

  I found this piece of code: char a = 1["ABC"]; A few quick test led me to the fact it was the same than writing: char a = "ABC"[1]; Which seems far more logical to me. So my questions: Why is this notation valid? Is there any reason to write something that way?
