reusability

I need to provide the same layout.xml file for an Activity for several different qualifiers. I know that there's a way to just reference one existing layout.xml instead of really copying it and having a duplicate one. But how? Can't find it in the Android docs right now... :-/ Anybody faster than me? EDIT: although I found this "solution" I am still not there. <?xml version="1.0" encoding="utf-8"?> <merge> <include layout="@layout/main_ltr"/> </merge> I need to point to a different qualifiers's layout file, not to another layout file in the same qualifier. Reason behind it: I specified the new

This is in NetBeans 6.5, Java 6. I have the following hierarchy in the NetBeans GUI Designer: JFrame JTabbedPane JPanel X <...> JPanel JButton JPanel Y <...> JButton Question: JPanel Y is identical to JPanel X, so I'd like to simply reuse JPanel X in both places, but how do I do this inside the GUI Builder? Attempts: I tried copy-pasting JPanel X, but it creates a full "deep" copy (JPanel X1, etc), duplicating everything in JPanel X. Some googling indicated it might be possible to add it to the Palette, but I haven't found a way to add a simple JPanel to the palette (as opposed to a complete

I am a CSS newbie. I am just wondering, is that possible to include one common class into another class? for example, .center {align: center}; .content { include .center here}; I came across css framework - Blueprint . We need to put the position information into HTML, e.g. <div class="span-4"><div class="span-24 last"> As such, we will place the positioning attribute inside html, instead of css. If we change the layout, we need to change html, instead of css. That's the reason I ask this question. If I can include .span-4 into my own css, i won't have to specify it in my html tag. cletus

I tried the suggestion from this question with very little success. Please... any help will be greatly appreciated! Here is my code: static void Main(string[] args) { IPEndPoint localpt = new IPEndPoint(IPAddress.Any, 6000); UdpClient udpServer = new UdpClient(localpt); udpServer.Client.SetSocketOption( SocketOptionLevel.Socket, SocketOptionName.ReuseAddress, true); UdpClient udpServer2 = new UdpClient(); udpServer2.Client.SetSocketOption( SocketOptionLevel.Socket, SocketOptionName.ReuseAddress, true); udpServer2.Client.Bind(localpt); // <<---------- Exception here } You have to set the socket

I'm learning the new Java 8 features, and while experimenting with streams ( java.util.stream.Stream ) and collectors, I realized that a stream can't be used twice. Is there any way to reuse it? Hank D If you want to have the effect of reusing a stream, you might wrap the stream expression in a Supplier and call myStreamSupplier.get() whenever you want a fresh one. For example: Supplier<Stream<String>> sup = () -> someList.stream(); List<String> nonEmptyStrings = sup.get().filter(s -> !s.isEmpty()).collect(Collectors.toList()); Set<String> uniqueStrings = sup.get().collect(Collectors.toSet());

I have a queue of jobs and I want to make a pool of 4 threads where I can throw my jobs at. What I am stuck at is in how to make the threads and keep them suspended while there is no work. JOB QUEUE | job1 | job2 | job3 | job4 | .. THREAD POOL | thread1 | thread2 | thread3 | thread4 | To create the threads I have currently at the initialisation point: for (t=0; t<num_of_threads; t++){ pthread_create(&(threads[t]), NULL, doSth2, NULL); } Where num_of_threads=4 and doSth2 is a function with nothing inside. So once I have created the 4 threads and they are done with doSth2, how can I give them

Can someone explain why this works with the pointer: char * str1; str1 = "Hello1"; str1 = "new string"; // but not this char str2 [] = "hello"; str2 = "four"; // or this char str3 []; str3 = "hello"; str3 = "hello"; tryurbest Why it works with pointers: When you say char * str1 in C, you are allocating a pointer in the memory. When you write str1 = "Hello"; , you are creating a string literal in memory and making the pointer point to it. When you create another string literal "new string" and assign it to str1 , all you are doing is changing where the pointer points. Why it doesn't work with
