• Where and how to store functions in asp.net.vb

  - by si

  Hi. I am using visual studio 2008, asp.net.vb I have various functions; 1 that calculates totals, 1 that calculates averages, 1 that calculates percentages etc. The data they act upon is different depending on the particular web page, but all my pages use these functions. So I want to know how I can store these functions in a single place so that all of my web pages can access the routines. At the moment all I know how to do is to write seperate functions in the code-behind for each individual web page. Obviously that is just so long winded and inefficient, but try as I might I can't figure out how to do it better. Please can anyone help. Many thanks.

• define global in a python module from C api

  - by wiso

  Sorry for the trivial question, but I can't find this infomation from the manual. I am developping a module for python using C api; how can I create a variabile that is seen as global from python? For example if my module is module I want to create a variable g that do this job: import module print module.g in particular g is an integer. Solution from Alex Martelli PyObject *m = Py_InitModule("mymodule", mymoduleMethods); PyObject *v = PyLong_FromLong((long) 23); PyObject_SetAttrString(m, "L", v); Py_DECREF(v);

• PHP - MySQL - Select runs indefinitely

  - by John

  I have three tables listings: id, pid, beds, baths, etc, etc, etc, db locations: id, pid, zip, lat, lon, etc, etc, etc, db images id, pid, height, width, raw, etc, etc, db id, pid & db are indexed. db just references the mls provider a particular item came from. in images the raw column holds raw image data there are about 15k rows in listings/locations, and about 120k rows in images so there are multiple rows that have the same pid. when i do "select pid from listings" or "select pid from locations" the query completes successfully in about 100ms. when i do "select pid from images" it just hangs in sqlyog and never completes... i was thinking since the raw column contains alot of information that it might be trying to select that too, but my query doesn't try to select that so I can't imagine why it's taking so long... any idea why this is happening??

• what is the best algorithm to use for this problem

  - by slim

  Equilibrium index of a sequence is an index such that the sum of elements at lower indexes is equal to the sum of elements at higher indexes. For example, in a sequence A: A[0]=-7 A[1]=1 A[2]=5 A[3]=2 A[4]=-4 A[5]=3 A[6]=0 3 is an equilibrium index, because: A[0]+A[1]+A[2]=A[4]+A[5]+A[6] 6 is also an equilibrium index, because: A[0]+A[1]+A[2]+A[3]+A[4]+A[5]=0 (sum of zero elements is zero) 7 is not an equilibrium index, because it is not a valid index of sequence A. If you still have doubts, this is a precise definition: the integer k is an equilibrium index of a sequence if and only if and . Assume the sum of zero elements is equal zero. Write a function int equi(int[] A); that given a sequence, returns its equilibrium index (any) or -1 if no equilibrium indexes exist. Assume that the sequence may be very long.

• Stored proc executes >30 secs when called from website, but <1 sec when called from ssms

  - by Blootac

  I have a stored procedure that is called by a website to display data. Today the web page has started timing out so I got profiler going and saw the query that was taking too long. I then ran the same query in management studio, under the same user login, and it takes less than a second to return. Is there anything obvious that could be causing this? I can't think of a reason why when ASP calls the stored proc it takes 30 secs but when I call it it's fine. Thanks

• jQuery fadeTo not working in IE8

  - by Lynda

  I have a div fading in using fadeTo. It works great in Firefox and IE9. It does not work in IE8. Here is my code: JS: var $j = jQuery.noConflict(); window.onload = function(){ $j('#fadein').fadeTo(6000, 1, function() { }); }; HTML <div class="img-center" id="fadein" style="opacity:0;"> <img src="src.jpg" alt="Text" class="feature-image" /> </div> How do I get this to work in IE8? I do not mind changing from fadeTo to fadeIn or some other method of fading in a div as long as it works in IE8.

• How can i make a callback to accordion after form validation, to show errors

  - by Esger

  I have a very long form, which is divided into fieldsets which in turn are being shown or hidden, using the harmonica from jQuery UI. I am using form validation from jQuery as well, all newest versions. After submission and validation the user is redirected to the first erroneous field by $('myForm').validate(); But the containing harmonica fieldset has to be showed/opened with $('myForm').accordion('activate', index); as well, in order to show the field to the user. So how can I open the appropriate accordion fieldset after the form has been tried to submit? Is there a way to do it in a callback function after $('myForm').validate();

• Black flicker while resizing translucent Qt widget (only when Aero is enabled)?

  - by D.

  I have a top-level Qt widget with the FramelessWindowHint flag and the WA_TranslucentBackground attribute set. It has several children, each of which draws an image on it. They are not in a layout. Instead, I simply move them around when something changes (it is not user-resizable). There are two states to the window - a big state and a small state. When I switch between them, I resize the window and reposition the children. The problem is that as the window resizes, a black box is briefly flashed on the top-level window before the images are painted over it. The problem goes away if I disable Aero. I found brief mention of this problem being fixed in an article describing a new release of Qt (this release is long past), but it still doesn't work. Any ideas why? Thanks!

• Track each URL and Parameters sent from Form

  - by Arjun

  Simple question really for anyone who's been through this: I have a form that I'm placing on a site. This form submits some parameters to a site which then sends some parameters using "GET" to another site, which then opens the third site. Now the first 2 sites pass so quickly that I can not see what parameters were passed using the URL. I can do a manual check using source code but its too long and complex. I just need a simple tool or hint or firefox addon on how to track every single URL (wven if it has a META redirect) so I can read parameters being sent via the form. Thanks

• sequentially-consistent atomic load on x86

  - by axe

  Hello all, I'm interested in sequentially-consistent load operation on x86. As far as I see from assembler listing, generated by compiler it is implemented as a plain load on x86, however plain loads as far as I know guaranteed to have acquire semantics, while plain stores are guaranteed to have release. Sequentially-consistent store is implemented as locked xchg, while load as plain load. That sounds strange to me, could you please explain this in details? added Just found in internet, that sequentially-consistent atomic load could be done as simple mov as long as store is done with locked xchg, but there was no prove and no links to documentation. Do you know where can I read about that? Thanks in advance.

• Finding the sum of 2D Arrays in Ruby

  - by Bragaadeesh

  Hi, I have an array of two dimensional Arrays. I want to create a new two dimensional array which finds the sum of these values in the 2D arrays. Sum at x,y of new array = Sum at x,y of arr1 + Sum at x,y of arr2 + .... |1,2,4| |1,1,1| |1,1,1| |2,4,6| |1,1,1| |1,1,1| |2,4,6| |1,1,1| |1,1,1| |2,4,6| |1,1,1| |1,1,1| Now adding the above two dimensional arrays will result in, |3,4,6| |4,6,8| |4,6,8| |4,6,8| How to achieve this in Ruby (not in any other languages). I have written a method, but it looks very long and ugly.

• Browser App - RAD UI Development - Is it possible?

  - by Randy Minder

  I've been away from building browser applications for a long time. I'm now interested in creating one for a hobby of mine. I dread having to deal with HTML, JavaScript etc. to build a high quality browser based user interface. I've got the full suite of Telerik controls. Is it possible to build a polished, somewhat feature rich browser UI while being sheltered from the archaic environment of HTML and JavaScript? I'd love to be able to simply drag-drop components, much like building a Win UI and have the exact HTML, JavaScript code created for me. Thanks!

• What's the difference between the box-model bug and the new box-sizing CSS?

  - by RKS

  In days (long past for some, and still present for others) the box-model bug was a bane to their existence. The idea that an element's width included the margin, border, and padding was blasphemous and an abomination to their senses. So we got away from it after thousands of internet blogs about the box-model hack. Now we get box-sizing, which will, wait for it, allow you to specify that a width contains the border, the margin, and the padding. We plaster a trendy new name for it, "CSS3 Flexbox," and now it's the freedom designers have been looking for. For those logical people who saw the box-model bug as not the bug and the W3C as the actual bug, this comes as a surprise. A reintroduction of this so-called bug and now we call it an enhancement? So can someone explain why this is different? I am honestly confused about this.

• Asp.Net gridview customization

  - by Kunal

  Hi If you go to http://ifdefined.com/btnet/bugs.aspx you will see a long list of sample data in an asp.net gridview control. What I need to do is something similar. I need to implement the filtering system by placing dropdown controls with dynamic values on the headers and then filter the record according to them. If you look carefully they are filtering the data based on multiple drodown selections as well. Kindly help me out. Any kind of input is highly appreciated. Thanks in advance for your time.

• Equivalent to produce field glow in other browsers?

  - by Liso22

  I was long using this to add a glow to focused fields, I accessed my page from Firefox for the first time and realized it doesn't work on it, and most likely not on explorer either. border: 1px solid #E68D29; outline-color: -webkit-focus-ring-color; outline-offset: -2px; outline-style: auto; outline-width: 5px; I had copy pasted it from another page so I'm not quite sure how it works. What is the equivalent for Firefox or Explorer? I mean how do I make a similar glow in other browsers? Thanks

• Best and shortest books on C++/STL/C#/J2SE to prepare for job inteview/tests

  - by Nerd

  I am a software developer with 10+ years commercial experience, I am comfortable with nearly all of imperative languages. But I realized that most of employers prefer not candidates who is able to deliver good software but those who is trained to answer questions like "what are ten differences between pointers and references in C++" or "what this messy code fragment will print". Last time I have read a book on C++ 15 years ago in secondary school and yes, that was Bjarne Stroustrup. But today I need something quick, without long philosophical explanations about polymorphism etc but with focus to silly interview tests. So, can you recommend any short and effective books to refresh my theoretical knowledge? Thank you.

• Slow first page load on asp.net site

  - by Tabloo Quijico

  Hi, Every now and then (always after a long period of idle-time, e.g. overnight) when I access a site built using asp.net - it takes around 15 seconds to load the page (15 seconds before I see any progress whatsoever, then the page comes up fast). Further pages on that site, or refreshes, are quick as usual - they are also fast on other machines, only the first one seems to take the 'hit'. Page tracing never through anything up (whole cycle was a fraction of a second) So my question is where else should I be looking? Perhaps IIS? Or could it still be my asp.net app and I'm just looking in the wrong place (the trace) for clues? As I don't have much control over the IIS server, anything I can check through asp.net would be more helpful, before I go ask that particular admin. cheers :D

• Why does DateTime to Unix time use a double instead of an integer?

  - by Earlz

  I'm needing to convert a DateTime to a Unix timestamp. So I googled it looking for some example code In just about all the results I see, they use double as the return for such a function, even when explicitly using floor to convert it to an integer. Unix timestamps are always integers. So what problem is there with using either long or int instead of double? static double ConvertToUnixTimestamp(DateTime date) { DateTime origin = new DateTime(1970, 1, 1, 0, 0, 0, 0); TimeSpan diff = date - origin; return Math.Floor(diff.TotalSeconds); }

• VS 2010 Error “Object reference not set to an instance of an object” when adding Service Reference f

  - by Andy

  I have a VS2010 (RTM) solution which contains: WCF Service project Console WCF client project Class project for DataContracts and members Class project for some simple classes I successfully added a service reference in the console client project and ran the client. I then did a long dev cycle repeatedly modifying the service then updating console service reference. I then changed the namespace and assembly names for the projects as well as the .cs using references and app.config. I of course missed some things as it would not build so I eventually removed the project references and the service reference, cleaned and built successfully. I then attempted to add the service reference again, it discovered it but threw the “Object reference not set to an instance of an object” when OK'ing. Fix in answer below...

• Developing a high-performance, scalable Comet application

  - by Rob

  Well, the title says most of it. I'm looking to develop a chat application that will hopefully become something more, and currently I'm considering my options for what I should build it on top of. I've taken a look at Tornado with Redis as my primary option - Tornado, being a Comet server, is perfect for long polling to retrieve the messages on Redis, which I have the intention of using as both a persistent data store, as well as a message queue with its nifty subpub features. However, I've also heard good things about Django, RabbitMQ, MongoDB and Orbited. JavaScript isn't a big problem for me, so Orbited's JavaScript support isn't too much of a boon. Really, I'd probably be happy to develop on the route I've chosen for myself, but if there are any gaping deficiencies in my plan, I'd like some kind person to point them out before I find I've wasted months on this.

• On a Hudson master node, what are the .tmp files created in the workspace-files folder?

  - by Patrick Johnmeyer

  Question: In the path HUDSON_HOME/jobs/<jobname>/builds/<timestamp>/workspace-files, there are a series of .tmp files. What are these files, and what feature of Hudson do they support? Background Using Hudson version 1.341, we have a continuous build task that runs on a slave instance. After the build is otherwise complete, including archiving the artifacts, task scanner, etc., the job appears to hang for a long period of time. In monitoring the master node, I noted that many .tmp files were being created and modified under builds//workspace=files, and that some of them were very large. This appears to be causing the delay, as the job completed at the same time that files in this path stopped changing. Some key configuration points of the job: It is tied to a specific slave node It builds in a 'custom workspace' It triggers a downstream job that builds in the same custom workspace on the same slave node

• C# (With .NET & Visual Studio) WebForms - How can I get the title of a page ..?

  - by Ashley Davies

  Prety long question; How can I do the following in C#: Open a webpage (Prefferably not visible) Check whether the page redirects to a different page (Site is down, 404, etc.) Check if the title is not equal to a said string Then seperately, (They need to click a confirm button) open their browser, and go to the adress of the first (It'll be the only one) hyperlink on the site. I literally have been looking on google for ages and haven't found anything similar to what I need. Whether you give me a link to a site with a tutorial on this area of programming or actual source code doesn't make a difference to me.

• C++ - defining static const integer members in class definition

  - by HighCommander4

  My understanding is that C++ allows static const members to be defined inside a class so long as it's an integer type. Why, then, does the following code give me a linker error? #include <algorithm> #include <iostream> class test { public: static const int N = 10; }; int main() { std::cout << test::N << "\n"; std::min(9, test::N); } The error I get is: test.cpp:(.text+0x130): undefined reference to `test::N' collect2: ld returned 1 exit status Interestingly, if I comment out the call to std::min, the code compiles and links just fine (even though test::N is also referenced on the previous line). Any idea as to what's going on? My compiler is gcc 4.4 on Linux.

• Regular Expression; Find whether a line contains any word with more than X characters.

  - by Simpsoid

  Hi, I am trying to use a Validator on a ASP.NET site and need to find whether the Street Address textbox contains a valid entry. Entries with words that are longer than X characters (in this case 25, with no punctuation or spaces) will cause the HTML on a printed A4 page to not wrap properly and therefore not to confrom to certain sizes correctly pushing the margins off. For a street address I want to match that something like "201 Long Road" is valid but "235 ReallyLongAndNarrowWindingRoadBesideTheRiver Street" is invalid. Using a Microsoft .Net Regular Expression Validator I need to know what the RegEx pattern might be. I think if it does find a match the Validator will fire correctly however if there is no match the Validator won't fire and the Update button (in this case) won't fire. Since Street addresses can contain Capital Letters and numbers etc. it will need to accomodate for that and also Spaces, Commas, Semi-Colons and Colons and Hyphens are valid characters too. Any help would be greatly appreciated as I am really stuck with this problem. Thanks, David
