I’ve been trying to do this for a while and finally found out how it’s done.
Use the Shadow option.

In the NX Client Configuration GUI –> General Tab –> Desktop Section –> Select Shadow in the drop down.
Then login and select which session to attach to (Local Machine, or any other session)

That should do it!

Couple of things to remember, even though NX does an excellent job and I love NX:

• Since my local machine has a Dual monitor configuration (with different resolutions), I had some blur issues (even when my client spanned two monitors) – Yes I have 4 monitors (2 for Windows and 2 for Linux)
• When connecting from my laptop (single monitor), the dual monitor layout on the local machine was squeezed into a single screen and made it difficult to read

Alt+Tab key combination catching can be achieved through a slight configuration change in your NX Client session.

In the NX Client GUI -> Advanced tab…
Check the Grab the keyboard when the client has focus

This is such a common task, yet needs a bit of thinking.

List <string> strList = getListOfString();
String[] strArr = strList.toArray(new String[strList.size()]);

One simple solution is to convert both strings to lower case and then use the contains() method.

public boolean containsIgnoreCase(String longString, String shortString) {
    return (longString.toLowerCase().contains(shortString.toLowerCase()));
}
