  • How to merge 2 XML streams in Java by XSLT

    - by user327933
    I'd like to merge 2 XML streams (strings) in Java, necessarily by XSLT (that I could change the transformation), but the problem is that the XMLs come as a string. There are many examples, but through the files. Can this be done without saving them in files? Thanks.

  • In which situation is the c++/c# namespace approach better than the Java approach?

    - by mike g
    The reason I ask this is that c# could easily have copied the java convention, or a variation of it, but opted for the more flexible approach of explicitly declaring namespaces inside files. As a Java programmer often there are things that I wish I could do differently, but namespaces is not one of them. The flexbility has a certain overhead (extra braces, extra decisions for developers, making it harder to view a projects contributions to the namespace, at least without a specialist IDE). So what practical examples are there when this flexiblity is advantageous?

  • When/Why to use Cascading in SQL Server?

    - by Joel Coehoorn
    When setting up foreign keys in SQL Server, under what circumstances should you have it cascade on delete or update, and what is the reasoning behind it? This probably applies to other databases as well. I'm looking most of all for concrete examples of each scenario, preferably from someone who has used them successfully.

  • Buffer size: N*sizeof(type) or sizeof(var)? C++

    - by flyout
    I am just starting with cpp and I've been following different examples to learn from them, and I see that buffer size is set in different ways, for example: char buffer[255]; StringCchPrintf(buffer, sizeof(buffer), TEXT("%s"), X); VS char buffer[255]; StringCchPrintf(buffer, 255*sizeof(char), TEXT("%s"), X); Which one is the correct way to use it? I've seen this in other functions like InternetReadFile, ZeroMemory and MultiByteToWideChar.

  • Adobe Flex Progress Bar for LoadStyleDeclarations

    - by Max
    I'm loading a rather large swf as style with the following command: StyleManager.loadStyleDeclarations("assets/modules/"style.swf",true,false,ApplicationDomain.currentDomain); The style is loaded fine but now I would like to add a progress bar to it, but I do not know how to do so. I am rather new to Flex and found only examples referring to HTML service calls. Thank You for Your Help. It would be great to receive a small code example.

  • Query parameter using JS framework ?

    - by Maxim Veksler
    Hi, I seem to not be able to find implementation from the common Ajax libraries (JQuery, mootools, prototypejs...) that would allow the operation of parsing the window.location.href for request parameter. I would expect something like: $P{"param1"} == "param1_value" Am I missing something? p.s. The web does contains implementation examples for such operations

  • How can I make XSLT work in chrome?

    - by Eric
    I have an XML document here that is served with a corresponding XSL file. The transformation is left to be executed client-side, without JavaScript. This works fine in IE (shock horror), but in Google Chrome, just displays the document's text nodes. I know that it is possible to do client-side XSL in Chrome, as I have seen examples of it, but I am yet to be able to replicate this success myself What am I doing wrong?

  • Creating semaphores with unmanaged code in C++

    - by Dororo
    I've been using the MSDN Library to create semaphores, located at: http://msdn.microsoft.com/en-us/library/system.threading.semaphore.aspx However, the examples are using Managed code (requires /clr), and I need to use Unmanaged code because FreeType doesn't like working with Managed code it seems. How would I go about creating 2 simple threads which use a semaphore if I'm using unmanaged code? Many thanks for your help.

  • Am I obliged to use ipv6 tunnel services if I want to be able to use it?

    - by Zagorax
    I was looking for configuring Slackware to use ipv6 but all instruction I found speak about using an ipv6 tunnel that encapsulate ipv6 request into ipv4 packet and send them to an external router that extracts ipv6 request and sends a reply (or, at least, this is what I understood). Is that necessary? Isn't there a way to configure a pure ipv6 system? If yes, could you please point me to a guide that clearly explain how to enable ipv6 without this trick? I would like to configure my Slackware desktop at first, and then do the same with my Centos server. EDIT: maybe I gave you too few information. Sorry. I'll write some more information thanks to the posted guide. ~$ test -f /proc/net/if_inet6 && echo "Running kernel is IPv6 ready" Running kernel is IPv6 ready So, it seems ipv6 is enabled in my kernel. Some other output from ifconfig, route and /etc/resolv.conf content (with opendns): ~$ /sbin/ifconfig wlan0 | grep inet6 inet6 addr: fe80::21f:3bff:fe60:cc5b/64 Scope:Link ~$ /sbin/route -A inet6 | grep wlan0 fe80::/64 :: U 256 0 0 wlan0 ff00::/8 :: U 256 0 0 wlan0 ~$ cat /etc/resolv.conf inet6 nameserver 2620:0:ccc::2 nameserver 208.67.222.222 nameserver 208.67.220.220 But still, with ping6 I can only ping localhost (::1). Everything else is unreachable. Normal ping works fine. That is why I was asking if I am obliged to use a tunnel.

  • Understanding Scope on Scala's For Loops (For Comprehension)

    - by T. Stone
    In Chapter 3 of Programming Scala, the author gives two examples of for loops / for comprehensions, but switches between using ()'s and {}'s. Why is this the case, as these inherently look like they're doing the same thing? Is there a reason breed <- dogBreeds is on the 2nd line in example #2? // #1 ()'s for (breed <- dogBreeds if breed.contains("Terrier"); if !breed.startsWith("Yorkshire") ) println(breed) // #2 {}'s for { breed <- dogBreeds upcasedBreed = breed.toUpperCase() } println(upcasedBreed)

  • What's the difference between using ProtocolType.IP and ProtocolType.Tcp

    - by Sekhat
    I've just answered problem with sockets in c# where in my example code I initializing my socket using ProtocolType.IP as this is what I've always used in my own code, and it has never caused me problems. But I see many examples specifying ProtocolType.Tcp. I guess, what I'm asking is, by using ProtocolType.IP instead of ProtocolType.Tcp is anything being performed differently under the hood that I should be aware of?

  • Change -- to . for all files in a directory

    - by Larry
    Hello, I need to rename all the files in a directory. Some examples of the source filenames are: alpha--sometext.381928 comp--moretext.7294058 The resultant files would be renamed as: alpha.sometext.381928 comp.moretext.7294058 The number of characters before and after the -- is not consistant. The script needs to work on current installations of Ubuntu and FreeBSD. These are lean LAMP servers so only the necessary packages have been installed. Thanks
