  • Advanced search page for wordpress

    - by Mighty Jack
    I have a wordpress site thats related to laptops niche. So I have multiple categories like Display(10inch, 13inch, 15inch...), Processor(AMD, Intel), HDD(120GB, 320GB, 500GB...) etc. The usual search is not good. I want to create an advanced search page where user can select from options(drop downs/checkboxes) in these different cats and the corresponding search results are displayed. Any directions about this will be great help (plugins/themes/hacks).

  • PHP edit unique row in table

    - by Robert
    I currently have a PHP form that uses AJAX to connect to MySQL and display records matching a user's selection (http://stackoverflow.com/questions/2593317/ajax-display-mysql-data-with-value-from-multiple-select-boxes) As well as displaying the data, I also place an 'Edit' button next to each result which displays a form where the data can be edited. My problem is editing unique records since currently I only use the selected values for 'name' and 'age' to find the record. If two (or more) records share the same name and age, I am only able to edit the first result.

  • New ASP.NET 4.0 Web routing rules based on domain country extension?

    - by Nick
    Consider multiple domains (with different country extensions) that go to one singe physical website. Depending on the country extension of the domain, I want to route to a specific subfolder while keeping the active domain! Examples: www.mydomain.com/we/about-us.aspx to www.mydomain.com/content/com/we/about-us.aspx www.mydomain.fr/we/about-us.aspx to www.mydomain.fr/content/fr/we/about-us.aspx www.mydomain.be/we/about-us.aspx to www.mydomain.be/content/be/we/about-us.aspx Is this possible with the new web routing features in ASP.NET 4.0? Thanks, Nick

  • user defined Copy ctor, and copy-ctors further down the chain - compiler bug ? programmers brainbug

    - by J.Colmsee
    Hi. i have a little problem, and I am not sure if it's a compiler bug, or stupidity on my side. I have this struct : struct BulletFXData { int time_next_fx_counter; int next_fx_steps; Particle particles[2];//this is the interesting one ParticleManager::ParticleId particle_id[2]; }; The member "Particle particles[2]" has a self-made kind of smart-ptr in it (resource-counted texture-class). this smart-pointer has a default constructor, that initializes to the ptr to 0 (but that is not important) I also have another struct, containing the BulletFXData struct : struct BulletFX { BulletFXData data; BulletFXRenderFunPtr render_fun_ptr; BulletFXUpdateFunPtr update_fun_ptr; BulletFXExplosionFunPtr explode_fun_ptr; BulletFXLifetimeOverFunPtr lifetime_over_fun_ptr; BulletFX( BulletFXData data, BulletFXRenderFunPtr render_fun_ptr, BulletFXUpdateFunPtr update_fun_ptr, BulletFXExplosionFunPtr explode_fun_ptr, BulletFXLifetimeOverFunPtr lifetime_over_fun_ptr) :data(data), render_fun_ptr(render_fun_ptr), update_fun_ptr(update_fun_ptr), explode_fun_ptr(explode_fun_ptr), lifetime_over_fun_ptr(lifetime_over_fun_ptr) { } /* //USER DEFINED copy-ctor. if it's defined things go crazy BulletFX(const BulletFX& rhs) :data(data),//this line of code seems to do a plain memory-copy without calling the right ctors render_fun_ptr(render_fun_ptr), update_fun_ptr(update_fun_ptr), explode_fun_ptr(explode_fun_ptr), lifetime_over_fun_ptr(lifetime_over_fun_ptr) { } */ }; If i use the user-defined copy-ctor my smart-pointer class goes crazy, and it seems that calling the CopyCtor / assignment operator aren't called as they should. So - does this all make sense ? it seems as if my own copy-ctor of struct BulletFX should do exactly what the compiler-generated would, but it seems to forget to call the right constructors down the chain. compiler bug ? me being stupid ? Sorry about the big code, some small example could have illustrated too. but often you guys ask for the real code, so well - here it is :D EDIT : more info : typedef ParticleId unsigned int; Particle has no user defined copyctor, but has a member of type : Particle { .... Resource<Texture> tex_res; ... } Resource is a smart-pointer class, and has all ctor's defined (also asignment operator) and it seems that Resource is copied bitwise. EDIT : henrik solved it... data(data) is stupid of course ! it should of course be rhs.data !!! sorry for huge amount of code, with a very little bug in it !!! (Guess you shouldn't code at 1 in the morning :D )

  • bm.el is broken.

    - by maindoor
    Is anyone using bm.el to traverse through bookmarks in multiple buffers ? If so did you notice that bm-next is broken ? I see several people using it but no one seems to have noticed this. The buggy version got into emacs-goodies as well. How do I go about debugging this ?

  • killing all instances of chrome on the command line?

    - by Fedor
    In some cases killing a single tab/process doesn't do it and I need to close Chrome entirely. Since Chrome has multiple processes, how can I close all of them at once? I know that... pgrep chrome returns all the pids, can someone tell me a trick that would allow me to close all of them by feeding them to another command or merging them to a csv or something?

  • How do I do high quality scaling of a image?

    - by pbhogan
    I'm writing some code to scale a 32 bit RGBA image in C/C++. I have written a few attempts that have been somewhat successful, but they're slow and most importantly the quality of the sized image is not acceptable. I compared the same image scaled by OpenGL (i.e. my video card) and my routine and it's miles apart in quality. I've Google Code Searched, scoured source trees of anything I thought would shed some light (SDL, Allegro, wxWidgets, CxImage, GD, ImageMagick, etc.) but usually their code is either convoluted and scattered all over the place or riddled with assembler and little or no comments. I've also read multiple articles on Wikipedia and elsewhere, and I'm just not finding a clear explanation of what I need. I understand the basic concepts of interpolation and sampling, but I'm struggling to get the algorithm right. I do NOT want to rely on an external library for one routine and have to convert to their image format and back. Besides, I'd like to know how to do it myself anyway. :) I have seen a similar question asked on stack overflow before, but it wasn't really answered in this way, but I'm hoping there's someone out there who can help nudge me in the right direction. Maybe point me to some articles or pseudo code... anything to help me learn and do. Here's what I'm looking for: 1. No assembler (I'm writing very portable code for multiple processor types). 2. No dependencies on external libraries. 3. I am primarily concerned with scaling DOWN, but will also need to write a scale up routine later. 4. Quality of the result and clarity of the algorithm is most important (I can optimize it later). My routine essentially takes the following form: DrawScaled( uint32 *src, uint32 *dst, src_x, src_y, src_w, src_h, dst_x, dst_y, dst_w, dst_h ); Thanks! UPDATE: To clarify, I need something more advanced than a box resample for downscaling which blurs the image too much. I suspect what I want is some kind of bicubic (or other) filter that is somewhat the reverse to a bicubic upscaling algorithm (i.e. each destination pixel is computed from all contributing source pixels combined with a weighting algorithm that keeps things sharp. EXAMPLE: Here's an example of what I'm getting from the wxWidgets BoxResample algorithm vs. what I want on a 256x256 bitmap scaled to 55x55. And finally: the original 256x256 image

  • Split a PDF by Bookmarks?

    - by Jason
    Going to be getting a single PDF that has been created by 'merging' multiple pdf's. When I view the merged PDF each single PDF is displayed as a bookmark. Is there any way to automatically split this up by bookmarks with a script? We would not know the page numbers, so that's not an option.

  • Variable declarations in header files - static or not?

    - by Rob
    When refactoring away some #defines I came across declarations similar to the following in a C++ header file: static const unsigned int VAL = 42; const unsigned int ANOTHER_VAL = 37; The question is, what difference, if any, will the static make? Note that multiple inclusion of the headers isn't possible due to the classic #ifndef HEADER #define HEADER #endif trick (if that matters). Does the static mean only one copy of VAL is created, in case the header is included by more than one source file?

  • php imap save massage to sent folder after sending

    - by user1108279
    I am stucked with this for two days. I am trying to use imap_append from PHP but no luck so far. I was able to to implement this code for single attachment but multiple attachments not working. <?php $authhost="{000.000.000.000:993/validate-cert/ssl}Sent"; $user="sadasd"; $pass="sadasd"; if ($mbox=imap_open( $authhost, $user, $pass)) { $dmy=date("d-M-Y H:i:s"); $filename="filename.pdf"; $attachment = chunk_split(base64_encode($filestring)); $boundary = "------=".md5(uniqid(rand())); $msg = ("From: Somebody\r\n" . "To: [email protected]\r\n" . "Date: $dmy\r\n" . "Subject: This is the subject\r\n" . "MIME-Version: 1.0\r\n" . "Content-Type: multipart/mixed; boundary=\"$boundary\"\r\n" . "\r\n\r\n" . "--$boundary\r\n" . "Content-Type: text/html;\r\n\tcharset=\"ISO-8859-1\"\r\n" . "Content-Transfer-Encoding: 8bit \r\n" . "\r\n\r\n" . "Hello this is a test\r\n" . "\r\n\r\n" . "--$boundary\r\n" . "Content-Transfer-Encoding: base64\r\n" . "Content-Disposition: attachment; filename=\"$filename\"\r\n" . "\r\n" . $attachment . "\r\n" . "\r\n\r\n\r\n" . "--$boundary--\r\n\r\n"); imap_append($mbox,$authhost,$msg); imap_close($mbox); } else { echo "<h1>FAIL!</h1>\n"; } ?> Now that raw code above is working but I am unable to add multiple attachments. In some cases I got message body base64 decoded and in message body lot of strange letters. Something like R0lGODlhkAEfAOYAAPSeZPONtdSIu+u2vv/La+5Rj8AhYPvWhOjtkfvi7MRImcjYse5DM6O+dOnl ..... I search all the web i still got no luck. Since I have dedicated server I also tried to implement some procmail+ postfix examples but also no luck. Can someone help?

  • Is this ruby code thread safe?

    - by Ben K.
    Is this code threadsafe? It seems like it should be, because @myvar will never be assigned from multiple threads (assuming block completes in < 1s). But do I need to be worried about a situation where the second block is trying to read @myvar as it's being written? require 'rubygems' require 'eventmachine' @myvar = Time.now.to_i EventMachine.run do EventMachine.add_periodic_timer(1) do EventMachine.defer do @myvar = Time.now.to_i # some calculation and reassign end end EventMachine.add_periodic_timer(0.5) do puts @myvar end end

  • C# Multi-Comparisons possible?

    - by Iggy Ma
    is it possible in some way to compare multiple variables to one constant in a if statement? It would be very helpful if instead of if ( col.Name != "Organization" && col.Name != "Contacts" && col.Name != "Orders" ) { } I could just say if ( col.Name != "Organization" || "Contacts" || "Orders" ) { } And I know I could use a list but in some instances I dont want to... Thanks!

  • What sql server isolation level should I choose to prevent concurrent reads?

    - by Brian Bolton
    I have the following transaction: SQL inserts a 1 new record into a table called tbl_document SQL deletes all records matching a criteria in another table called tbl_attachment SQL inserts multiple records into the tbl_attachment Until this transaction finishes, I don't want others users to be aware of the (1) new records in tbl_document, (2) deleted records in tbl_attachment, and (3) modified records in tbl_attachment. Would Read Committed Isolation be the correct isolation level?

  • Tomcat session stickiness in session replication

    - by rabbit
    Hi, I am having a 2 instance load balanced and session replicated tomcat 6.0.20 cluster. Should sticky_session be set to true or false for in memory session replication. http://tomcat.apache.org/connectors-doc/reference/workers.html mentions : Set sticky_session to False when Tomcat is using a Session Manager which can persist session data across multiple instances of Tomcat. where as /tomcat-6.0-doc/cluster-howto.html (Cluster Basics) mentions : Make sure that your loadbalancer is configured for sticky session mode.

  • Which design pattern should be used to create an emulator?

    - by Facon
    I have programmed an emulator, but I have some doubts about how to organizate it properly, because, I see that it has some problems about classes connection (CPU <- Machine Board). For example: I/O ports, interruptions, communication between two or more CPU, etc. I need for the emulator to has the best performance and good understanding of the code. PD: Sorry for my bad English. EDITED - Asking for multiple patterns.

  • C++ Virtual Constructor, without clone()

    - by Julien L.
    I want to perform "deep copies" of an STL container of pointers to polymorphic classes. I know about the Prototype design pattern, implemented by means of the Virtual Ctor Idiom, as explained in the C++ FAQ Lite, Item 20.8. It is simple and straightforward: struct ABC // Abstract Base Class { virtual ~ABC() {} virtual ABC * clone() = 0; }; struct D1 : public ABC { virtual D1 * clone() { return new D1( *this ); } // Covariant Return Type }; A deep copy is then: for( i = 0; i < oldVector.size(); ++i ) newVector.push_back( oldVector[i]->clone() ); Drawbacks As Andrei Alexandrescu states it: The clone() implementation must follow the same pattern in all derived classes; in spite of its repetitive structure, there is no reasonable way to automate defining the clone() member function (beyond macros, that is). Moreover, clients of ABC can possibly do something bad. (I mean, nothing prevents clients to do something bad, so, it will happen.) Better design? My question is: is there another way to make an abstract base class clonable without requiring derived classes to write clone-related code? (Helper class? Templates?) Following is my context. Hopefully, it will help understanding my question. I am designing a class hierarchy to perform operations on a class Image: struct ImgOp { virtual ~ImgOp() {} bool run( Image & ) = 0; }; Image operations are user-defined: clients of the class hierarchy will implement their own classes derived from ImgOp: struct CheckImageSize : public ImgOp { std::size_t w, h; bool run( Image &i ) { return w==i.width() && h==i.height(); } }; struct CheckImageResolution; struct RotateImage; ... Multiple operations can be performed sequentially on an image: bool do_operations( std::vector< ImgOp* > v, Image &i ) { std::for_each( v.begin(), v.end(), /* bind2nd(mem_fun(&ImgOp::run), i ...) don't remember syntax */ ); } int main( ... ) { std::vector< ImgOp* > v; v.push_back( new CheckImageSize ); v.push_back( new CheckImageResolution ); v.push_back( new RotateImage ); Image i; do_operations( v, i ); } If there are multiple images, the set can be split and shared over several threads. To ensure "thread-safety", each thread must have its own copy of all operation objects contained in v -- v becomes a prototype to be deep copied in each thread.
