  • vb.net how to check for changes in folder upon application start?

    - by Luay
    while the application is running i'm using FileSystemWatcher to monitor the folder. But what if there are changes to the folder when the application is not running, how can I check for these changes when the application starts. (similar to how windows media player, for example, monitors your music folder. Even when you add songs to that folder when it is not running, it does discover them when it runs next time) Thanks

  • Javascript: why I cannot load my external js page in Drupal ?

    - by Patrick
    hi, when I add the tag script to load an external javascript file, my page is not longer displayed. There are not error in Firebug, there are not errors such as "File not found" or "Not enough permissions", the browser just displays a blank page for some reason. <?php print $head; ?> <?php print $styles; ?> <?php print $scripts; ?> <script type="text/JavaScript" src="main.js" /> If I remove the last line everything works perfectly. The previous php lines are the standard Drupal head lines. This is the content of my js file: $(document).ready( function() { alert("hello"); }); thanks

  • regexp to match string with (comma-separated) number at start and to split into number and rest?

    - by mix
    Given a string such as: 23,234,456 first second third How can I split string this into two parts, where part 1 contains the number at the beginning and part 2 contains the rest---but only if the string STARTS with a number, and the number can be comma-separated or not? In other words, I want two results: 23,234,456 and first second third. If there's a number in that string that isn't part of the first number then it should be in the second result. My best stab at this so far, to grab the number at the beginning, is something like this: ^[0-9]+(,[0-9]{3})* Which seems to grab a comma-separated or non-comma-separated number that starts the line. However, when I run this in the Javascript console I get not only the full number, but also a match on just the last 3 digits with their preceeding ,. (e.g. 23,234,456 and ,456). As for getting the rest into another var I'm having trouble. I tried working with \b, etc., but I think I must be missing something fundamental about grabbing the rest of the line. I'm doing this in Javascript in case it matters. More examples of what to match and what not to match. 2 one two three should return 2 and one two three 2345 one two three should return 2345 and one two three 2 one 2 three should return 2 and one 2 three 2,234 one two 3,000 should return 2,234 and one two 3,000 The space between parts 1 and two could be included in the beginning of part 2.

  • I need to create a web service using .NET-- where should I start?

    - by j-t-s
    Hi All I am trying to implement a feature. But I've never had anything to do with "Web Services" before, other than using them. I have a desktop application, and I want that application to be able to sort of "post" some information (i.e. email address, username, user-selected options (just plain text) etc) to an application or "web service" on my ASP.NET web server. Can somebody please guide me in the right direction? How would I accomplish this? Thank you :) Jason

  • What do you do in your source control repository when you start a rewrite of a program?

    - by Max Schmeling
    I wrote an application a while back and have been maintaining it for a while now, but it's gotten to the point where there's several major new features to be added, a ton of changes that need made, and I know quite a few things I could do better, so I'm starting a rewrite of the entire program (using bits and pieces from original). My question is, what do you do with SVN at this point? Should I put the new version somewhere else, or should I delete the files I no longer need, add the new files, and just treat it like normal development in SVN? How have you handled this in the past?

  • Where to start to create an HTML website with 2 tables read from csv files using anything but php

    - by CodingIsAwesome
    I want to design a website which displays on loading two tables each with it's respective data from a csv file. Then every minute the website automatically refreshes. This problem seems so simple! But yet the solution eludes me. All of the files will be contained in 1 directory, not on a server but on a local machine. Such as sitting on the desktop. I understand if I use javascript I have to use ADO, and I'm still trying to work out how to use ASP. I am new with both languages. So far the only restriction is that I can't use PHP. So the jist so far as I can think right now is: 1. read the file 2. place the file into an array by splitting at the commas 3. write the array into td's ????? 4. then print all this out into a div ???? I have googled my heart out and can't seem to find what I'm looking for. or even piece together what I'm looking for. Everything with javascript and ADO's leads me to dead ends, I can't find anything on ASP that is helpful. Could someone please write up some sample code for a resource? Or have a better solution?

  • Cannot bind to list<T>.property or list<T>.item.property in details section of Telerik report

    - by fluf
    I have created a Telerik report and I am setting the datasource on runtime to an object with some properties and a List. I am using the properties in the page and report header sections and i want to use the list as the details. Now the problem is binding to the List's item properties in the details section. I have played around with the expression builder and it seems that i should access the properties like this : [=Fields.myList.Item.myProperty] when i run the program i get a nice big red rectangle with the following error : An error has occured while processing TextBox 'textBox28':Common Language Runtime detected an invalid program. I have tried to change different variants of expression which also gives me other errors [=Fields.myList.myPropery] An error has occured while processing TextBox 'textBox28': The expression contains object 'myProperty' that is not defined in the current context. The closest i have gotton was with the object it self, which outputs the object.toString() [=Fields.myList]

  • When does code bloat start having a noticeable effect on performance?

    - by Kyle
    I am looking to make a hefty shift towards templates in one of my OpenGL projects, mainly for fun and the learning experience. I plan on watching the size of the executable carefully as I do this, to see just how much of the notorious bloat happens. Currently, the size of my Release build is around 580 KB when I favor speed and 440 KB when I favor size. Yes, it's a tiny project, and in fact even if my executable bloats 10 x its size, it's still going to be 5 MB or so, which hardly seems large by today's standards... or is it? This brings me to my question. Is speed proportional to size, or are there leaps and plateaus at certain thresholds, thresholds which I should be aiming to stay below? (And if so, what are the thresholds specifically?)

  • How to start doing TDD in a django project?

    - by Satoru.Logic
    Hi, all. I have read a lot of essays talking about benifits TDD can bring to a project, but I have never practiced TDD in my own project before. Now I'm starting an experimental project with Django, and I think maybe I can have a try of TDD. But what I find now is that I don't even know how to answer the question "what should I put in my test cases?". Please tell me how should I plan TDD in a project, in this case, a web project based on Django. Thanks.

  • Should .net comments start with a capital letter and end with a period?

    - by Hamish Grubijan
    Depending on the feedback I get, I might raise this "standard" with my colleagues. This might become a custom StyleCop rule. is there one written already? So, Stylecop already dictates this for summary, param, and return documentation tags. Do you think it makes sense to demand the same from comments? On related note: if a comment is already long, then should it be written as a proper sentence? For example (perhaps I tried too hard to illustrate a bad comment): //if exception quit vs. // If an exception occurred, then quit. If figured - most of the time, if one bothers to write a comment, then it might as well be informative. Consider these two samples: //if exception quit if (exc != null) { Application.Exit(-1); } and // If an exception occurred, then quit. if (exc != null) { Application.Exit(-1); } Arguably, one does not need a comment at all, but since one is provided, I would think that the second one is better. Please back up your opinion. Do you have a good reference for the art of commenting, particularly if it relates to .Net? Thanks.

  • How do I prevent a pair of XMLEvent[Reader|Writer] from splitting empty tags into start+end tags?

    - by java.is.for.desktop
    Hello, everyone! I have an understanding problem of how the following code works: XMLInputFactory xif = XMLInputFactory.newFactory(); XMLOutputFactory xof = XMLOutputFactory.newFactory(); XMLEventReader reader = xif.createXMLEventReader(/* ... */); XMLEventWriter writer = xof.createXMLEventWriter(/* ... */); writer.add(reader); The method writer.add([some reader]) reads all events from reader and writes them consequently. Sadly, following happens: The input <root><c/></root> gets transformed to <root><c><c/></root> I know, from XML point of view, these are equal trees, but not for a human ;) What can I do to get the same output? FYI: I need a XMLEvent[Reader|Writer] pair later to filter "XML events".

  • Why do virtual memory addresses for linux binaries start at 0x8048000?

    - by muteW
    Disassembling an ELF binary on a Ubuntu x86 system I couldn't help but notice that the code(.text) section starts from the virtual address 0x8048000 and all lower memory addresses seem to be unused. This seems to be rather wasteful and all Google turns up is either folklore involving STACK_TOP or protection against null-pointer dereferences. The latter case looks like it can be fixed by using a single page instead of leaving a 128MB gap. So my question is this - is there a definitive answer to why the layout has been fixed to these values or is it just an arbitrary choice?
