  • What is the right way to structure HTML and CSS?

    - by Meke
    So, I'm a script monkey at the core. Lately I seem to get stuffed into doing design too for some odd reason and, well, let's just say I should probably have studied better. Either way - What I ask is, what's the Right way to structure a website? This one has a header with links, then a block with tabs, right under another block which consists of two parts and under those a few others who I'm not at yet. However, the thing is, I need to make a block that consists of two parts that are in the same box but structured independently. I'll try to draw it up. Browser window..................-[]X ------------------------------------ |.................Header Links Here| ||Tab|Tab|Tab|_____________........| ||Tab content.............|Small...| ||........................|Section.| ||---Line signing new section------| ||........................|Another.| ||..Content Area..........|Small...| ||........................|Section.| ------------------------------------ My issue is in the division of small sections and tab/content areas. I tried using floats, making them as tables, aligning and whatnot. The putting float:left on both tables worked. Kinda. Until I tried to resize the window. So, how do you PROPERLY structure a site like this? three divs and tables? Something else? I'll clarify this again: It's the Code to use to create the look above that I'm trying to figure out the proper way to do, not the design As requested here's the current structure I have <div class="container"> <div class="topBlock"> //Header Links Here </div> <div class="inputBlock"> <ul id="tabs"> <li><a href="#strict">Strict</a></li> <li><a href="#flex">Flex</a></li> <li><a href="#multiStep">Multi-Step</a></li> </ul> <div id="strict" class="tabContent"> <table class="tableLeft"> <tr> <td>From</td> </tr> <tr> <td><input id="inputBlockFrom" type="text" placeholder="FROM"/></td> </tr> <tr> <td>To</td> </tr> <tr> <td><input id="inputBlockTo" type="text" placeholder="TO"/></td> </tr> </table> <table class="tableRight"> <tr> <td>Leave</td> </tr> <tr> <td><input id="inputBlockLeave" type="text" name="leave" placeholder="LEAVE"/></td> <td><input id="inputBlockOne" type="radio" name="one"/></td> <td>One</td> </tr> <tr> <td>Return</td> </tr> <tr> <td><input id="inputBlockReturn" type="text" name="return" placeholder="RETURN"/></td> <td><input id="inputBlockBut" type="radio" name="one" checked/></td> <td>Return</td> </tr> <tr> <td><input id="inputBlockSubmit" type="submit" value="Search"/></td> </tr> </table> </div> <div id="flex" class="tabContent"> Test Two </div> <div id="multiStep" class="tabContent"> Test Three </div> </div> <div class="mapBlock tabContent"> <table class="tableLeft"> <tr><td> <div id="map" class="google_map"></div> </td></tr> </table> <table class="tableRight smallTable"> <tr> <td>Distance</td> </tr> <tr> <td>[-------------|------------]</td> //Slider to be </tr> </table> <table class="tableRight smallTable"> <tr> <td>Choice / Choice</td> </tr> </table> <table class="tableRight"> <tr> <td>Show:</td> </tr> <tr> <td><input type="radio"/></td> <td>Price</td> <td><input type="radio"/></td> <td>Button!</td> </tr> <tr> <td><input type="radio"/></td> </tr> <tr> <td><input type="radio"/></td> </tr> </table> </div> </div> </body> Sorry if it's messed up in the whitespacing somewhere.. The CSS: body { font-size: 80%; font-family: 'Lucida Grande', Verdana, Arial, Sans-Serif; background-color: #e2edff; } .container { margin: 5px 5px 5px 5px; padding: 5px 5px 5px 5px; } .pageBlock { /* To future me: This class is for One Full Screen ideas */ min-height: 300px; } .topBlock { text-align: right; color: #000000; } .topBlock a { text-decoration: none; color: #000000; } .tableLeft { width: 75%; float: left; border-right: dotted 2px black; } .tableRight { float: left; overflow: auto; } .smallTable { border-bottom: 1px dotted #c9c3ba; } .google_map { height: 270px; width: 100%; }

  • WinForms: How to prevent textbox from opening alt menu?

    - by Digiku
    I have this textbox I use to capture keyboard shortcuts for a preferences config. I use a low-level keyboard hook to capture keys and also prevent them from taking action, e.g. the Windows key, but the Alt key still comes through and makes my textbox lose focus. How can I block the Alt key, so the focus is kept unaltered at my textbox?

  • Is there an application I can show a client the speed of their site via differring internet connecti

    - by Slimpickens
    I have a new client with an old website using massive amounts of tables and inline styles. Some page weigh over 3MB due to huge backgrounds and other large images. I suggested they at least compress the files to speed up the site but they're convinced it's fast. Since they have 13Mbit connection at the office everything seems fast. I'm looking for a tweak, program or web app capable of loading pages at varying speeds so they understand how it might load for slower DSL or (gasp) dialup users. Thanks for any help!

  • An operator == whose parameters are non-const references

    - by Eduardo León
    I this post, I've seen this: class MonitorObjectString: public MonitorObject { // some other declarations friend inline bool operator==(/*const*/ MonitorObjectString& lhs, /*const*/ MonitorObjectString& rhs) { return lhs.fVal==rhs.fVal; } } Before we can continue, THIS IS VERY IMPORTANT: I am not questioning anyone's ability to code. I am just wondering why someone would need non-const references in a comparison. The poster of that question did not write that code. This was just in case. This is important too: I added both /*const*/s and reformatted the code. Now, we get back to the topic: I can't think of a sane use of the equality operator that lets you modify its by-ref arguments. Do you?

  • Custom Memory Allocator for STL map

    - by Prasoon Tiwari
    This question is about construction of instances of custom allocator during insertion into a std::map. Here is a custom allocator for std::map<int,int> along with a small program that uses it: #include <stddef.h> #include <stdio.h> #include <map> #include <typeinfo> class MyPool { public: void * GetNext() { return malloc(24); } void Free(void *ptr) { free(ptr); } }; template<typename T> class MyPoolAlloc { public: static MyPool *pMyPool; typedef size_t size_type; typedef ptrdiff_t difference_type; typedef T* pointer; typedef const T* const_pointer; typedef T& reference; typedef const T& const_reference; typedef T value_type; template<typename X> struct rebind { typedef MyPoolAlloc<X> other; }; MyPoolAlloc() throw() { printf("-------Alloc--CONSTRUCTOR--------%08x %32s\n", this, typeid(T).name()); } MyPoolAlloc(const MyPoolAlloc&) throw() { printf(" Copy Constructor ---------------%08x %32s\n", this, typeid(T).name()); } template<typename X> MyPoolAlloc(const MyPoolAlloc<X>&) throw() { printf(" Construct T Alloc from X Alloc--%08x %32s %32s\n", this, typeid(T).name(), typeid(X).name()); } ~MyPoolAlloc() throw() { printf(" Destructor ---------------------%08x %32s\n", this, typeid(T).name()); }; pointer address(reference __x) const { return &__x; } const_pointer address(const_reference __x) const { return &__x; } pointer allocate(size_type __n, const void * hint = 0) { if (__n != 1) perror("MyPoolAlloc::allocate: __n is not 1.\n"); if (NULL == pMyPool) { pMyPool = new MyPool(); printf("======>Creating a new pool object.\n"); } return reinterpret_cast<T*>(pMyPool->GetNext()); } //__p is not permitted to be a null pointer void deallocate(pointer __p, size_type __n) { pMyPool->Free(reinterpret_cast<void *>(__p)); } size_type max_size() const throw() { return size_t(-1) / sizeof(T); } void construct(pointer __p, const T& __val) { printf("+++++++ %08x %s.\n", __p, typeid(T).name()); ::new(__p) T(__val); } void destroy(pointer __p) { printf("-+-+-+- %08x.\n", __p); __p->~T(); } }; template<typename T> inline bool operator==(const MyPoolAlloc<T>&, const MyPoolAlloc<T>&) { return true; } template<typename T> inline bool operator!=(const MyPoolAlloc<T>&, const MyPoolAlloc<T>&) { return false; } template<typename T> MyPool* MyPoolAlloc<T>::pMyPool = NULL; int main(int argc, char *argv[]) { std::map<int, int, std::less<int>, MyPoolAlloc<std::pair<const int,int> > > m; //random insertions in the map m.insert(std::pair<int,int>(1,2)); m[5] = 7; m[8] = 11; printf("======>End of map insertions.\n"); return 0; } Here is the output of this program: -------Alloc--CONSTRUCTOR--------bffcdaa6 St4pairIKiiE Construct T Alloc from X Alloc--bffcda77 St13_Rb_tree_nodeISt4pairIKiiEE St4pairIKiiE Copy Constructor ---------------bffcdad8 St13_Rb_tree_nodeISt4pairIKiiEE Destructor ---------------------bffcda77 St13_Rb_tree_nodeISt4pairIKiiEE Destructor ---------------------bffcdaa6 St4pairIKiiE ======Creating a new pool object.

Why is this necessary? Is there a way to suppress this? Thanks! Edit: This code tested on x86 machine with g++ version 4.1.2. If you wish to run it on a 64-bit machine, you'll have to change at least the line return malloc(24). Changing to return malloc(48) should work.

  • set timeout to http response read method in python

    - by nirtayeb
    Hi, I'm building a download manager in python for fun, and sometimes the connection to the server is still on but the server doesn't send me data, so read method (of HTTPResponse) block me forever. This happens, for example, when I download from a server, which located outside of my country, that limit the bandwidth to other countries. How can I set a timeout for the read method (2 minutes for example)? Thanks, Nir.

  • Filling a screen width

    - by lorna
    I'm really struggling to tidy up a web site I am building for someone. I've spent hours on trying to figure this out! I have limited knowledge so the code would be helpful. They want the section at the top (originally two images, now I'm trying background images and css) to fill the width of the browser- no matter what size it is. Does anyone know how to do this? Similarly, is there a setting to get text to fill 100% width of the box, no matter what? I would seriously appreciate even someone helping me move on a step! they want everything to sit tight and inline, in some browsers/screens it does but on mine it spreads out with lots of white space. www.thegees.co.uk is the site.

  • Is there an IDE that provides code completion for Python

    - by Justin Walgran
    I am quite fond of the Intellisense code completion baked into Microsoft Visual Studio. I find that I only type 2 to 4 characters of any given keyword which drasticaly speeds up my coding. Now that I have been spending time writing some Python code I find myself reaching for ctrl+space. Are there any IDEs that support code completion in Python? I do my python development on a Mac so an OS x tool would be preferable. It seems like the doc string property of Python methods is a perfect match for inline API discovery.

  • Starting to construct a data access layer. Things to consider?

    - by Phil
    Our organisation uses inline sql. We have been tasked with providing a suitable data access layer and are weighing up the pro's and cons of which way to go... Datasets ADO.net Linq Entity framework Subsonic Other? Some tutorials and articles I have been using for reference: http://www.asp.net/(S(pdfrohu0ajmwt445fanvj2r3))/learn/data-access/tutorial-01-vb.aspx http://www.simple-talk.com/dotnet/.net-framework/designing-a-data-access-layer-in-linq-to-sql/ http://msdn.microsoft.com/en-us/magazine/cc188750.aspx http://msdn.microsoft.com/en-us/library/aa697427(VS.80).aspx http://www.subsonicproject.com/ I'm extremely torn, and finding it very difficult to make a decision on which way to go. Our site is a series of 2 internal portals and a public web site. We are using vs2008 sp1 and framework version 3.5. Please can you give me advise on what factors to consider and any pro's and cons you have faced with your data access layer. Thanks.

  • Memory Leak from Foundation & CFNetwork Library

Specifically, the leaks are from: 1. NSCFString 2. NSConcreteData 3. General Block-3584 Since they do not directly point to the code that I have written, how should I resolve them, if I have to?

  • Audio/video streaming on Windows platform

    - by bushtucker
    I'm building an interactive language learning application to be used in a classroom environment. The idea is that a teacher should be able to talk to the students (=audio stream to all students), let students talk to each other (= audio P2P) in groups of two or more, let students watch a video coming from a the DVD player or coming from a media server. It should be possible to save the audio/video streams. The teacher should also be able to monitor, take-over or block the desktop of the students. The platform is Windows and it's a desktop application, no web application. The audio delay should be as minimal as poosible. Optionally a student sitting at home should be supported, but it's not a high priority. I am now finished with the classroom control part of the application (login, monitor, block, ...) and want to start the audio and video part. I've been evaluating several options like DirectX, GStreamer and SIP but now I have to make a decision. DirectX seems an obvious choice for the Windows platform, but it only lets me capture and playback audio and video. The encoding/decoding/network part I should do myself. GStreamer contains all kinds of options to capture/encode/stream/save audio and video streams. I've experimented a bit with it (ossbuild) and it does seem to involve a lot of trial and error to make something work: - microphone capture (via directsoundsrc) produces cracking noises on some computers - rtpL16 payloader didn't work well - streaming raw audio over the network only working at a sampling rate of 8000, no higher - there are a lot of errors when receiving mpeg4 video (bad I-frame), on some computers worse than others It is my impression that gstreamer is primary targetted at linux platforms. Development and support for the Windows platform seems to be a little behind. Nevertheless it's a powerful framework that could save me months and years of work. SIP seems to be able to do everything I want, but it is targeted towards telephony and IM. I don't know how flexible SIP is. It seems to me that the SIP layer would just be overhead as I already have a central (teacher) application that can control and setup all the streams. The interesting parts of frameworks like opalvoip and freeswitch are the actual audio/video capture, the encoding and transmission. Does anyone know how these interesting parts relate a framework like gstreamer? Are they easy to integrate into a custom application? Are they flexible enough? Does anyone have experience with all or one of these technologies? Maybe there are even other options I can look at? Many thanks for your advice
