  • Struts2 converting empty string parameter to an "int"

    - by Kyle Partridge
    How does one convert an empty string to an int using Struts2. When the application encounters this parameter with no value, like from an empty text field, it throws the following exception. java.lang.NoSuchMethodException: com.XXXXXXXXXXXX.setID([Ljava.lang.String;) Where ID is an integer, and the URL is: Something.action?ID=&other=rawr Is there a way to do this without using an Integer (class)? Do I have to write a type converter?

    - by nathan kelly
    Trying to find emails from an inbox using exchange webservices (against exchange 2007). the subject of which should not be empty. Tried the following: searchFilterCollection.Add(new SearchFilter.IsNotEqualTo(EmailMessageSchema.Subject, string.Empty)); and searchFilterCollection.Add(new SearchFilter.IsNotEqualTo(EmailMessageSchema.Subject, null)); but no luck. What do I need to do to get those messages that have a subject?

  • Using read() directly into a C++ std:vector

    - by Joe
    I'm wrapping up user space linux socket functionality in some C++ for an embedded system (yes, this is probably reinventing the wheel again). I want to offer a read and write implementation using a vector. Doing the write is pretty easy, I can just pass &myvec[0] and avoid unnecessary copying. I'd like to do the same and read directly into a vector, rather than reading into a char buffer then copying all that into a newly created vector. Now, I know how much data I want to read, and I can allocate appropriately (vec.reserve). I can also read into &myvec[0], though this is probably a VERY BAD IDEA. Obviously doing this doesn't allow myvec.size to return anything sensible. Is there any way of doing this that 1) Doesn't completely feel yucky from a safety/C++ perspective and 2) Doesn't involve two copies of the data block - once from kernel to user space and once from a C char * style buffer into a C++ vector. Any thoughts collective?

  • WordPress plugin to output a certain category on content page tweak help

    - by talkingD0G
    I'm using WordPress plugin Category Page to display the most recent 5 posts from a certain category on a regular content page (not the blog page) of a website. Right now the plugin is limited to display the post title linked to the post page. This is a video blog type site and I need the plugin to display the post title (as it does now) with the video as well. Probably just telling the script to show the content would work but I don't know how to tweak it. This is the section of the script that is outputting the post title: function page2cat_content_catlist($content){ global $post; if ( stristr( $content, '[catlist' )) { $search = "@(?:<p>)*\s*\[catlist\s*=\s*(\w+|^\+)\]\s*(?:</p>)*@i"; if (preg_match_all($search, $content, $matches)) { if (is_array($matches)) { $title = get_option('p2c_catlist_title'); if($title != "") $output = "<h4>".$title."</h4>"; else $output = ""; $output .= "<ul class='p2c_catlist'>"; $limit = get_option('p2c_catlist_limit'); foreach ($matches[1] as $key =>$v0) { $catposts = get_posts('category='.$v0."&numberposts=".$limit); foreach($catposts as $single): $output .= "<li><a href='".get_permalink($single->ID)." '>".$single->post_title."</a></li>"; endforeach; $search = $matches[0][$key]; $replace= $output; $content= str_replace ($search, $replace, $content); } $output .= "</ul>"; } } } return $content; } If anyone has any advice or knows how to help thanks in advance!

  • [PHP] - Output buffer based progress bar

    - by KPL
    Hello people, I have been trying to get the following code working. It's a progress bar trick which uses ob_get_clean() function. Don't know why but this script just don't work! Only the initial percent - 1% comes up and nothing after that. <?php error_reporting(8191); function flush_buffers(){ @ob_end_flush(); @ob_flush(); @flush(); @ob_start(); } $ini = 2; echo '<script>document.getElementById(\'lpt\').style.width=\'1%\';</script><br>'; for($i=1;$i<=100;$i++) { $k=$ini-1; $str=str_replace("width=\'$k%\'","width=\'$i%\'",ob_get_clean()); $ini++; echo $str; flush_buffers(); } ?>

  • displaying a saved buffer in OpenGL ES

    - by Adam
    Hi everyone, So basically I have a screenshot that I've saved that I want to later display on the screen. I've saved it with: glReadPixels(0, 0, self.bounds.size.width, self.bounds.size.height, GL_RGBA, GL_UNSIGNED_BYTE, savedBuffer); And later I'm trying to write it to the screen with: GLuint RenderedTex; glGenTextures(1, &RenderedTex); glEnable(GL_TEXTURE_2D); glBindTexture(GL_TEXTURE_2D, RenderedTex); glTexImage2D (GL_TEXTURE_2D, 0, GL_RGBA, self.bounds.size.width, self.bounds.size.height, 0, GL_RGBA, GL_UNSIGNED_BYTE, savedBuffer); glDisable(GL_TEXTURE_2D); I'm pretty new to OpenGL so I don't know if I'm doing things right... actually I know I'm not, because nothing shows up. Also not sure how to dispose of the texture when I'm done with it. Anyone know the correct way to do this? Edit: I think I might be having a problem loading the texture because it's not a power of 2, it's 320x480... also, I think this code is just loading the texture, but not drawing it, I'd need a call to glDrawArrays(GL_TRIANGLE_STRIP, 0, 4) in there somewhere...

  • vim plugin to show current Perl subroutine

    - by Andrew
    I'm trying to make a vim plugin that will split the window on load and simulate a info bar at the top of my terminal. I've got it sorta working but I think I've either reached limits of my knowledge of vim syntax or there's a logic problem in my code. The desired effect would be to do a reverse search for any declaration of a Perl subroutine form my current location in the active buffer and display the line in the top buffer. I'm also trying to make it skip that buffer when I switch buffers with <C-R>. My attempt at that so far can be seen in the mess of nested if statements. Anyway, here's the code. I would greatly appreciate feedback from anyone.

  • Protocol buffer deserialization and a dynamically loaded DLL in Compact Framework

    - by cloudraven
    I saw a question related to this on the full framework here. Since it seems to have stayed unresolved for quite a while and this is for the compact framework, I though it would be better to create a new question for it. I want to deserialize types for which I am loading assemblies dynamically (with Assembly.LoadFrom) and I am getting a "Unable to identify known-type for ProtoIncludeAttribute" error. In the related question I mentioned, it was hinted that hooking AppDomain.AssemblyResolve event would help solving the problem. It makes sense for the full framework, but that event is not available in the CF. I wonder if there is a way to do this with CF. The structures I am using look a lot like this and all the classes required for deserialization are loaded from the same Assembly. If the assembly is referenced instead of dynamically loaded it works fine, but fails if done dynamically.

  • How large is a "buffer" in PostgreSQL

    - by Konrad Garus
    I am using pg_buffercache module for finding hogs eating up my RAM cache. For example when I run this query: SELECT c.relname, count(*) AS buffers FROM pg_buffercache b INNER JOIN pg_class c ON b.relfilenode = c.relfilenode AND b.reldatabase IN (0, (SELECT oid FROM pg_database WHERE datname = current_database())) GROUP BY c.relname ORDER BY 2 DESC LIMIT 10; I discover that sample_table is using 120 buffers. How much is 120 buffers in bytes?

  • OpenAL device, buffer and context relationship

    - by Markus
    I'm trying to create an object oriented model to wrap OpenAL and have a little problem understanding the devices, buffers and contexts. From what I can see in the Programmer's Guide, there are multiple devices, each of which can have multiple contexts as well as multiple buffers. Each context has a listener, and the alListener*() functions all operate on the listener of the active context. (Meaning that I have to make another context active first if I wanted to change it's listener, if I got that right.) So far, so good. What irritates me though is that I need to pass a device to the alcCreateContext() function, but none to alGenBuffers(). How does this work then? When I open multiple devices, on which device are the buffers created? Are the buffers shared between all devices? What happens to the buffers if I close all open devices? (Or is there something I missed?)

  • TCP and UDP are using different OS Buffer?

    - by Jack
    HI all. Here is the scenario. I have port 8888 for my program to use. I build a TCP and a UDP listener on that port. (This can do, c# allows, because they are two different protocols) My question is If the network traffic is very busy, TCP sockets may refuse or signalling the other end to stop sending things, it is called congestion control, right? So if TCP is congestion controlling, other ends may not send more data, in this "TCP quiet period", UDP channel should have not that much of traffic, right? I want to figure out the TCP traffic will affect UDP traffic or not?

  • Copying a byte buffer with JNI

    - by Daniel
    I've found plenty of tutorials / questions on Stackoverflow that deal with copying char arrays from C/JNI side into something like a byte[] in Java, but not the other way around. I am using a native C library which expects a byte array. I simply want to get data from a byte[] in java, into preferably an unsigned char[] in C. Long story short: What is the best way of copying data from a jBytearray in JNI? Is there any way to detect it's size?

  • ctypes buffer modification

    - by Chris
    Hi, I need to call a c library from my python code. The c library does a lot of image manipulation, so I am passing it image buffers allocated using create_string_buffer. The problem is that I also need to manipulate and change these buffers. What is the best way to reach in and twiddle individual values in my buffers? The buffers are all uint8 buffers. Thanks!

  • Can piping of screen to file change the result of a C++ code?

    - by Biga
    I am having this very weird behaviour with a C++ code: It gives me different results when running with and without piping the screen to a file (reproducible in cygwin and linux). I mean, if I get the same executable and run it like './run' or run it like './run out.log', I get different results! I use std::cout to output to screen, all lines ending with endl; I use ifstream for the input file; I use ofstream for output, all lines ending with endl. I am using g++ 4. Any idea what is going on? UPDATE: I have hard-coded the input data, so 'ifstream' is not used, and problem persists. UPDATE 2: That's getting interesting. I have output three variables that are computed initially, and that's what I get with and without piping direct to screen: 0 -0.02 0 piped: 0 -0.02 1.04083e-17 So there's a round-off difference with and without piping the output! Now, why piping would interefere with an internal computation of the code?

  • Display "iftop" on web

    - by DmitrySemenov
    I do iftop -i eth1 > out.txt It does produce the file with "encrypted" UI content such as [(B[)0[[1;80r[[mO[[?7h[[?1h[=[[H[[J[[0;7mO Listening on eth1 [[1;48H[[mO12.5Kb Is it possible to display this as a web xhtml output somehow? cat out.txt on my console does produce a normal iftop window but when I do the same thing over the web I get the content above. I understand that it is "managed" on kernel level. Is the task that I want to perform possible?

  • Boost::asio bug in MSVC10 - Failing BOOST_WORKAROUND in ~buffer_debug_check() in buffer.hpp

    - by shaz
    A straight compilation of example http://www.boost.org/doc/libs/1_43_0/doc/html/boost_asio/tutorial/tutdaytime3/src.html results in a runtime null pointer exception. Stack trace points to the buffer_debug_check destructor which contains this comment: // MSVC's string iterator checking may crash in a std::string::iterator // object's destructor when the iterator points to an already-destroyed // std::string object, unless the iterator is cleared first. The test #if BOOST_WORKAROUND(BOOST_MSVC, = 1400) succeeds in MSVC10 and (but) results in a null pointer exception in c:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\include\xutility line 123 _Iterator_base12& operator=(const _Iterator_base12& _Right) { // assign an iterator if (_Myproxy != _Right._Myproxy) _Adopt(_Right._Myproxy->_Mycont); return (*this); } _Right._Myproxy is NULL
