• Scolling list with jQuery

  - by Chris

  My javascript is not up to scratch at the moment and I am stumped with this! I need to create an animated list with javascript like this one - http://www.fiveminuteargument.com/blog/scrolling-list. What I want is to take a list like so <ul> <li>Item 1</li> <li>Item 2</li> <li>Item 3</li> <li>Item 4</li> <li>Item 5</li> <li>Item 6</li> </ul> And display two at once, then display them in a loop, 2 at a time. Even pseudo code would help to get me started.

• How do C++ header files work?

  - by PulpFiction

  Hi all. When I include some function from a header file in a C++ program, does the entire header file code get copied to the final executable or only the machine code for the specific function is generated. For example, if I call std::sort from the <algorithm> header in C++, is the machine code generated only for the sort() function or for the entire <algorithm> header file. I think that a similar question exists somewhere on Stack Overflow, but I have tried my best to find it (I glanced over it once, but lost the link). If you can point me to that, it would be wonderful.

• UI to allow 700+ multiple choices

  - by Refracted Paladin

  In my desktop .NET application I have written(for internal use) where I need to allow my users to apply diagnosis's to a Member Plan. There are currently 700 in the system and growing. I need to allow them to add multiple diapnosis's at once. I currently am allowing this through a combo check list box. This works but is INSANELY unweildly for both myself and the users. What I am looking for is a how I could go about displaying these to the users. Ideally I would need to show two criteria for each each as well. Diagnosis Name and Diagnosis Code Ideas? How would you tackle this? I am using .Net 3.5sp1 and SQL 2005 for the backend. I don't care if the solution is WPF or Winforms.

• left join without duplicate values using MIN()

  - by Clipper87

  I have a table_1: id custno 1 1 2 2 3 3 and a table_2: id custno qty descr 1 1 10 a 2 1 7 b 3 2 4 c 4 3 7 d 5 1 5 e 6 1 5 f When I run this query to show the minimum order quantities from every customer: SELECT DISTINCT table_1.custno,table_2.qty,table_2.descr FROM table_1 LEFT OUTER JOIN table_2 ON table_1.custno = table_2.custno AND qty = (SELECT MIN(qty) FROM table_2 WHERE table_2.custno = table_1.custno ) Then I get this result: custno qty descr 1 5 e 1 5 f 2 4 c 3 7 d Customer 1 appears twice each time with the same minimum qty (& a different description) but I only want to see customer 1 appear once. I don't care if that is the record with 'e' as a description or 'f' as a description. How could I do this ? Thx!

• Analog of Java Form Layout in Qt

  - by Narek

  Once I have programmed GUI with Java and have used Form Layouts. Form layout (if I am not mistaken that is from SWT library) made possible to give right, left, top and bottom adges of any GUI element (widget) with respect to other widgets in the same widget (parent widget) or with respect to the adges of parent widget. So it was possible to control the future of widgets that are inside of another one, when that "another widget" is being resized. In Qt I have find the QFormLayout which is similar to Java one, but seems I can't handle with widgets as flexible in terms of relative positioning, as it was with Java's Form Layout. So are there any other means to give a widget position with respect to the others (without overloading resizeEvent function) as that was in Java? Thanks.

• An explanation of memory usage on Windows server 2003

  - by Rich

  Hi, We've been working on a bit of puzzle at work. We have an application service installed on two machines, both running Windows server 2003. These services do exactly the same thing. However once loaded, one of the services uses 200mb less than the other service. We're at a bit of a loss to what might be causing this discrepancy. I was wondering if there was some kind of server setting that would cause an application to use more memory (heap block size) or anything to explain this. If anyone has any ideas on what may be causing this, or how to find out what is causing this I'd be very grateful. Cheers Rich

• What is wrong with my loop?

  - by user3966541

  I have the following loop and don't understand why it only runs once: std::vector<sf::RectangleShape> shapes; const int res_width = 640; const int res_height = 480; for (int x = 0; x < res_width / 50; x += 50) { for (int y = 0; y < res_height / 50; y += 50) { sf::RectangleShape shape(sf::Vector2f(50, 50)); shape.setPosition(x * 50, y * 50); sf::Color color = (x % 2 == 0) ? sf::Color::Green : sf::Color::Red; shape.setFillColor(sf::Color::Green); shapes.push_back(shape); } }

• AtomicInteger for limited sequnce generation

  - by satish

  How can we use AtomicInteger for limited sequence generation say the sequence number has to be between 1 to 60. Once the sequece reaches 60 it has to start again from 1. I wrote this code though not quite sure wether this is thread safe or not? public int getNextValue() { int v; do { v = val.get(); if ( v == 60) { val.set(1); } } while (!val.compareAndSet(v , v + 1)); return v + 1; }

• What is this C function supposed to do based on description?

  - by user1261445

  unsigned int hex_c0c0c0c0(): Allowed operators: + - = & | ~ << ! >> Allowed constants: 1 2 4 8 16 Return 0xc0c0c0c0 The above is the description I have been given and I have to write the code for it. Can someone tell me what exactly the function is supposed to do? All the description says is what I have pasted above, so I'm not sure what my goal is. I'm sure it is an easy enough function to program on my own, but it would help if someone could tell me what the function is supposed to do, and maybe provide sample input/output so that I know my code is working correctly once I program this. Thanks.

• Embarassing C++ question regarding const

  - by Neil Butterworth

  My comments on this answer got me thinking about the issues of constness and sorting. I played around a bit and reduced my issues to the fact that this code: #include <vector> int main() { std::vector <const int> v; } will not compile - you can't create a vector of const ints. I suppose I should have known this, but I've never needed to create such a thing before. However, it seems like a useful construct to me, and I wonder if there is any way round this problem - I want to add things to a vector (or whatever), but they should not be changed once added. There's probably some embarrassingly simple solution to this, but it's something I'd never considered before.

• SQL Server Replication

  - by Serge

  I have a device that continuously collects data and stores it on a local database. I would like to also replicate that data to a second computer over the network every 10 seconds to ensure data reliability. Should I use transaction replication to achieve this? What if the network connection is temporarily unavailable, will the replication service automatically transmit all the backlogged data once the connection is restored? Can the computer that collects the data be SQL Server Compact or does it have to be at least Workgroup edition to be a Publisher. The second PC will run SQL Server Express and would be a subscriber. Thanks.

• Hosted Continuous Application Monitoring Services

  - by Ian Silber

  Does anybody know of a good service or tool for continuos application monitoring? I'm looking specifically for something that is hosted, so we don't have to worry to much about the fact that the monitoring tool is actually running. Specifically, we have a few e-commerce customers that we would like to provide detailed monitoring services for. We don't want to simply monitor uptime, we'd like to go through the entire checkout process once a day or even more often to ensure everything's working (adding to cart, shipping calculations, payment processing, etc). We've tried site24x7.com but their recording tool just doesn't seem to offer the level of customization we need. Does anybody have any recommendations?

• Querying Postgresql with a very large result set

  - by sanity

  In an application I need to query a Postgres DB where I expect tens or even hundreds of millions of rows in the result set. I might do this query once a day, or even more frequently. The query itself is relatively simple, although may involve a few JOINs. My question is: How smart is Postgres with respect to avoiding having to seek around the disk for each row of the result set? Given the time required for a hard disk seek, this could be extremely expensive. If this isn't an issue, how does Postgres avoid it? How does it know how to lay out data on the disk such that it can be streamed out in an efficient manner in response to this query?

• Throwing an AggregateException in my own code

  - by Pat

  How should I go about collecting exceptions and putting them into an AggregateException to re-throw? For my specific code, I have a loop and will have zero or more exceptions thrown from a part of the code. I was hoping to just add the new exceptions to the AggregateException as they arise, but the documentation sort of indicates that it should be constructed with all the Exceptions at once (there is no method to add an Exception to the object). And what about creating a new AE every time and just including the previous AE in the list of exceptions? Seems a hokey way to do it. Any better ideas?

• Robust Way of Selecting All Text in Textbox

  - by Emil

  I'm trying to have the content of the an HTML textbox be selected fully onFocus. I know the simple solution of putting a onfocus="this.select()" on the component but this is not a good solution because if a user double clicks into the area the selection is lost and in browsers like chrome it is rarely working like it should and just reverts into input form. I have searched on Google for a little while and can't find a good solution, most suggestions are of this simple solution. What I would like it is that the selection inside the textbox not change once selected and if possible the user should not be able to edit the content of the textbox, for example if you have used AdSense when you grab code from AdSense the selection never changes and your unable to alter the code in the textbox. Any solutions would be appreciated.

• How to manage memory for ios with large csv files?

  - by Pell000

  I'm new to ios development, and I'm running into issues relating to memory management and my approaches to dealing with large datasets. Right now, I am loading the csv files and storing the relevant data as objects in memory at app initialization. Some of the csv files are larger than 1MB, and in total, my app uses about 180MB of memory. This is obviously way too high of a number (unless the info I found is wrong and this is an acceptable number, then please let me know). I feel as though there is a fundamental flaw in my approach: is there a way I can avoid storing the csv files in the project itself? Or, is there a kind of "lazy" loading I can do so that I can simply look up info in the csv file, as opposed to loading all of the data from it at once? Any help would do. I think that I need a new perspective in how to manage this more efficiently.

• Managing a list of threads

  - by Satanlike

  Hi, I have an application (.Net 3.5) which creates threads to write something to the database so that the GUI does not block. All created threads are added to a list, so that I can wait (Thread.Join) for each thread when the application is closed (maybe not all threads are finished when the application is closed, so the app must wait for them). Because of the list I get some serious problems if there are too many threads created (OutOfMemoryException). I tried removing finished threads from the list, but somehow that didn't work. Are there better ways to manage a list of threads, so I can remove them once they are finished?

• Restrict confirm message on page reload with f5

  - by Max

  In my JSP page I am using post method while submitting the page. So once I go from Page 1 to page 2. In Page 2, If I press F5 I am getting alert as "To display this page, Firefox must send information that will repeat any action (such as a search or order confirmation) that was performed earlier." I knew this question is a bit sarcastic but please give me an Idea. I can't change my method from POST to GET because I need to send large amount of data. Thanks in advance... Edited: In my Page1.JSP I call onClick function in that function I call action as "/page2servlet.do". Now, In Java side I use Spring Framework. With MVC Object I return to page2.jsp. So where do the response.sendRedirect Fit.

• WPF Button on or off coloured state

  - by wonea

  I'm trying to create a set of button which have an off or on state, much a checkbox without the check. Ideally I want the colour to change to represent the two different states off(red), green(on). I've tried setting a control template but this only changes the colour for a selection, then reverts back to it's original colour once the mouse leaves the button's vicinity. <ControlTemplate.Triggers> <Trigger Property="IsPressed" Value="True"> <Setter Property="Background" TargetName="Background" Value="Green"/> </Trigger> </ControlTemplate.Triggers>

• Core Data-Linking one-to-many relationships

  - by Stelmate

  I have a one-to-many relationship where each department has many employees. When I create a new employee object I just link it to the parent department manually by setting the property to the instance of the department I have fetched from my fetch request. However, this seems to be improper because when I try to access the set of employees from the department by simply accessing the .employees property on my department object instance it returns a 0 count. Isn't the fault suppose to fire once I access a property? Am I linking my parent/child objects incorrectly?

• Trying to zoom in on an arbitrary rect within a screen-aligned quad.

  - by mos

  I've got a screen-aligned quad, and I'd like to zoom into an arbitrary rectangle within that quad, but I'm not getting my math right. I think I've got the translate worked out, just not the scaling. Basically, my code is the following: // // render once zoomed in glPushMatrix(); glTranslatef(offX, offY, 0); glScalef(?wtf?, ?wtf?, 1.0f); RenderQuad(); glPopMatrix(); // // render PIP display glPushMatrix(); glTranslatef(0.7f, 0.7f, 0); glScalef(0.175f, 0.175f, 1.0f); RenderQuad(); glPopMatrix(); Anyone have any tips? The user selects a rect area, and then those values are passed to my rendering object as [x, y, w, h], where those values are percentages of the viewport's width and height.

• nextSibling issue, should be simple

  - by SoLoGHoST

  Ok, I'm trying to come to grips with this nextSibling function in JS. Here's my issue within the following code... var fromRow = document.getElementById("row_1"); while(fromRow.nodeType == 1 && fromRow.nextSibling != null) { var fRowId = fromRow.id; if (!fRowId) continue; // THIS ONLY gets done once and alerts "row_1" ONLY :( alert(fRowId); fromRow = fromRow.nextSibling; } Ok can someone please tell me what is wrong with this code? There are siblings next to this document.getElementById("row_1"); element for sure as I can see them, and they all have id attributes, so why is it not getting the id attributes of the siblings?? I don't get it. row_1 is a TR element, and I need to get the TR elements next to it within this table, but for some reason, it only gets the 1 element that I can already get using document.getElementById, arggg. Thanks guys :)

• Portrait vs Landscape Launch Images

  - by andrewx

  An iPad app can support inclusion of launch images in both orientations; presumably, if your app supports auto-rotation, then this would suggest to me that if the user launches an app while the device is in Landscape mode, then the Landscape launch image is used. But in all the apps I've built and released, this has never been the case. Never once has the Landscape launch image appeared, only the Portrait. After loading, the app will auto-rotate to whatever orientation the device is in, but at launch, it assumes you are in Portrait. Always. Why? I have seen many other apps in the store that behave this way, but then there are some seem to always automatically know immediately at first launch, from that first launch image, that you are in Landscape, if that's the case. How is this done?

• Obtain distances to nearest landmarks (Mall, Hospital, and Airport etc.) using google map

  - by user227290

  I am working on a project in which I have around 100000 addreses in major cities in India(it is a table in a database). I want to know if it is possible to obtain the distances to to nearest landmarks (Mall, Hospital, and Airport etc.). Ideally I want these distances to be mergeed to the parent table. We have Java and Php coders to get it done once we find out how to go about it. Any pointers will be of great help. Thank you.
