  • PHP Ampersand in String

    - by John
    Hello. I'm having a bit of a problem. I am trying to create an IRC bot, which has an ampersand in its password. However, I'm having trouble putting the ampersand in a string. For example... <?php $var = "g&abc123"; echo $var; ?> I believe this should print g&abc123. However it's printing g. I have tried this as well: <?php $arr = array("key" => "g&abc123"); print_r($arr); ?> This prints it correctly with the g&abc123, however when I say echo $arr['key']; it prints g again. Any help would be appreciated. I'm running PHP5.3.1. EDIT: Also, I just noticed that if I use g&abc123&abc123 it prints g&abc123. Any suggestions?

  • Passing a WHERE clause for a Linq-to-Sql query as a parameter

    - by Mantorok
    Hi all This is probably pushing the boundaries of Linq-to-Sql a bit but given how versatile it has been so far I thought I'd ask. I have 3 queries that are selecting identical information and only differ in the where clause, now I know I can pass a delegate in but this only allows me to filter the results already returned, but I want to build up the query via parameter to ensure efficiency. Here is the query: from row in DataContext.PublishedEvents join link in DataContext.PublishedEvent_EventDateTimes on row.guid equals link.container join time in DataContext.EventDateTimes on link.item equals time.guid where row.ApprovalStatus == "Approved" && row.EventType == "Event" && time.StartDate <= DateTime.Now.Date.AddDays(1) && (!time.EndDate.HasValue || time.EndDate.Value >= DateTime.Now.Date.AddDays(1)) orderby time.StartDate select new EventDetails { Title = row.EventName, Description = TrimDescription(row.Description) }; The code I want to apply via a parameter would be: time.StartDate <= DateTime.Now.Date.AddDays(1) && (!time.EndDate.HasValue || time.EndDate.Value >= DateTime.Now.Date.AddDays(1)) Is this possible? I don't think it is but thought I'd check out first. Thanks

  • How to maintain a persistant network-connection between two applications over a network?

    - by John
    I was recently approached by my management with an interesting problem - where I am pretty sure I am telling my bosses the correct information but I really want to make sure I am telling them the correct stuff. I am being asked to develop some software that has this function: An application at one location is constantly processing real-time data every second and only generates data if the underlying data has changed in any way. On the event that the data has changed send the results to another box over a network Maintains a persistent connection between the both machines, altering the remote box if for some reason the network connection went down From what I understand, I imagine that I need to do some reading on doing some sort of TCP/IP socket-level stuff. That way if the connection is dropped the remote location will be aware that the data it has received may be stale. However management seems to be very convinced that this can be accomplished using SOAP. I was under the impression that SOAP is more or less a way for a client to initiate a procedure from a server and get some results via the HTTP protocol. Am I wrong in assuming this? I haven't been able to find much information on how SOAP might be able to solve a problem like this. I feel like a lot of people around my office are using SOAP as a buzzword and that has generated a bit of confusion over what SOAP actually is - and is capable of. Any thoughts on how to accomplish this task would be appreciated!

  • Java Swing custom shapes (2D Graphics)

    - by juFo
    I need to draw custom shapes. Now when a user clicks on several points on the panel I create a shape using a polygon. public void mouseClicked(MouseEvent e) { polygon.addPoint(e.getX(), e.getY()); repaint(); } But I don't know if this is the best way to draw custom shapes. It should be possible to edit a drawn shape: resize change its fill color change the stroke color copy/paste it move a single point of the polygon ... I have seen people creating an own class implementing the Shape class and using a GeneralPath. But again I have no idea if this is a good way. Now I can create my own shape with a polygon (or with a GeneralPath) but I have no clue how to attach all the edit functions to my own shape (the edit functions I mean the resize, move, etc from above). I hope somebody could show me a way to do this or maybe write a little bit of code to demonstrate this. Thanks in advance!!

  • How do the operators < and > work with pointers?

    - by Øystein
    Just for fun, I had a std::list of const char*, each element pointing to a null-terminated text string, and ran a std::list::sort() on it. As it happens, it sort of (no pun intended) did not sort the strings. Considering that it was working on pointers, that makes sense. According to the documentation of std::list::sort(), it (by default) uses the operator < between the elements to compare. Forgetting about the list for a moment, my actual question is: How do these (, <, =, <=) operators work on pointers in C++ and C? Do they simply compare the actual memory addresses? char* p1 = (char*) 0xDAB0BC47; char* p2 = (char*) 0xBABEC475; e.g. on a 32-bit, little-endian system, p1 p2 because 0xDAB0BC47 0xBABEC475? Testing seems to confirm this, but I thought it'd be good to put it on StackOverflow for future reference. C and C++ both do some weird things to pointers, so you never really know...

  • Javascript Getting Objects to Fallback to One Another

    - by Ian
    Here's a ugly bit of Javascript it would be nice to find a workaround. Javascript has no classes, and that is a good thing. But it implements fallback between objects in a rather ugly way. The foundational construct should be to have one object that, when a property fails to be found, it falls back to another object. So if we want a to fall back to b we would want to do something like: a = {sun:1}; b = {dock:2}; a.__fallback__ = b; then a.dock == 2; But, Javascript instead provides a new operator and prototypes. So we do the far less elegant: function A(sun) { this.sun = sun; }; A.prototype.dock = 2; a = new A(1); a.dock == 2; But aside from elegance, this is also strictly less powerful, because it means that anything created with A gets the same fallback object. What I would like to do is liberate Javascript from this artificial limitation and have the ability to give any individual object any other individual object as its fallback. That way I could keep the current behavior when it makes sense, but use object-level inheritance when that makes sense. My initial approach is to create a dummy constructor function: function setFallback(from_obj, to_obj) { from_obj.constructor = function () {}; from_obj.constructor.prototype = to_obj; } a = {sun:1}; b = {dock:2}; setFallback(a, b); But unfortunately: a.dock == undefined; Any ideas why this doesn't work, or any solutions for an implementation of setFallback? (I'm running on V8, via node.js, in case this is platform dependent)

  • Maven3 Issues with building a multi-module enterprise project

    - by Sujit K
    I just migrated from Maven2 to Maven3 and I'm able to build each module individually or all the modules in one shot by calling mvn clean install. However, in Maven2, since we have multi-module enterprise project, we build multiple ear's and each ear is built as its own module with its own child pom. To build an individual ear with its dependents, the below command works fine in Maven2 but not in Maven3. Let me explain the issue in Maven3 a bit later. mvn -pl ear_module -rf first_dependent_module -am clean install In Maven2 when the reactor lists the build order, I see first_dependent_module second_dependent_module ear_module End of the day I have my ear module also part of the reactor which is how it should be. The reason we call -rf is we don't want to delete the target folder at the main ${project.basedir} (so not to delete the output created in target from building the other ear modules). With Maven3, however, this is all I see when the reactor lists the build order: first_dependent_module second_dependent_module Maven3 totally ignores the argument (ear_module) set to -pl flag to be also built after its dependents have been. Not sure what I'm missing here. Any help/tips would be greatly appreciated. P.S: The build I'm making is similar to the one below.... Build specific module in multi-module project Thanks, SK

  • How do I update the UI during an event using ASP.NET?

    - by Phil Hale
    I'm a bit stuck with a problem. I feel like the solution should be fairly straight forward but I'm completely out of ideas for some reason. Here's the problem. I've got a user control with a couple of buttons. Think of them as 'On' and 'Off'. When either button is clicked an async method is called. If the method is successful an event is fired. Within the event I want to update the enabled property of the two buttons so that only a single button is clickable at any one time. The problem is that any changes I make to the properties are not shown on screen because the postback is already complete. I tried wrapping the buttons in an UpdatePanel but I get an "Update method can only be called on UpdatePanel with ID 'xxxx' before Render' error. I understand why the problem occurs but I can't think of a solution. Help! Ideally what I'd like to do is simply call a method within the event that will update the UI, but I don't know if that's possible.

  • Insert Stored Procedure does not Create Database Record

I am trying to insert a new record from my signup.aspx page. My SQLDataSource is as follows: <asp:SqlDataSource runat="server" ID="dsAddMember" ConnectionString="rmsdbuser" InsertCommandType="StoredProcedure" InsertCommand="Pro_members_Insert" ProviderName="System.Data.SqlClient"> The click handler for btnSave is as follows: Protected Sub btnSave_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btnSave.Click Try dsAddMember.DataBind() Catch ex As Exception End Try End Sub When I run this page, signup.aspx, provide required fields and click submit, the page simply reloads and the database table does not reflect the newly-inserted record. Questions: 1. How do I catch the error messages that might be returned from the sproc? 2. Please advise how to change signup.aspx so that the insert occurs. Thanks, Sid

  • Testing a method used from an abstract class

    - by Bas
    I have to Unit Test a method (runMethod()) that uses a method from an inhereted abstract class to create a boolean. The method in the abstract class uses XmlDocuments and nodes to retrieve information. The code looks somewhat like this (and this is extremely simplified, but it states my problem) namespace AbstractTestExample { public abstract class AbstractExample { public string propertyValues; protected XmlNode propertyValuesXML; protected string getProperty(string propertyName) { XmlDocument doc = new XmlDocument(); doc.Load(new System.IO.StringReader(propertyValues)); propertyValuesXML= doc.FirstChild; XmlNode node = propertyValuesXML.SelectSingleNode(String.Format("property[name='{0}']/value", propertyName)); return node.InnerText; } } public class AbstractInheret : AbstractExample { public void runMethod() { bool addIfContains = (getProperty("AddIfContains") == null || getProperty("AddIfContains") == "True"); //Do something with boolean } } } So, the code wants to get a property from a created XmlDocument and uses it to form the result to a boolean. Now my question is, what is the best solution to make sure I have control over the booleans result behaviour. I'm using Moq for possible mocking. I know this code example is probably a bit fuzzy, but it's the best I could show. Hope you guys can help.

  • Static Vs Non-Static Method Performance C#

    - by dotnetguts
    Hello All, I have few global methods declared in public class in my asp.net web application. I have habbit of declaring all global methods in public class in following format public static string MethodName(parameters) { } I want to know how it would impact on performance point of view? 1) Which one is Better? Static Method or Non-Static Method? 2) Reason why it is better? Following link shows Non-Static methods are good because, static methods are using locks to be Thread-safe. The always do internally a Monitor.Enter() and Monitor.exit() to ensure Thread-safety. http://bytes.com/topic/c-sharp/answers/231701-static-vs-non-static-function-performance And Following link shows Static Methods are good static methods are normally faster to invoke on the call stack than instance methods. There are several reasons for this in the C# programming language. Instance methods actually use the 'this' instance pointer as the first parameter, so an instance method will always have that overhead. Instance methods are also implemented with the callvirt instruction in the intermediate language, which imposes a slight overhead. Please note that changing your methods to static methods is unlikely to help much on ambitious performance goals, but it can help a tiny bit and possibly lead to further reductions. http://dotnetperls.com/static-method I am little confuse which one to use?

  • caching previous return values of procedures in scheme

    - by Brock
    In Chapter 16 of "The Seasoned Schemer", the authors define a recursive procedure "depth", which returns 'pizza nested in n lists, e.g (depth 3) is (((pizza))). They then improve it as "depthM", which caches its return values using set! in the lists Ns and Rs, which together form a lookup-table, so you don't have to recurse all the way down if you reach a return value you've seen before. E.g. If I've already computed (depthM 8), when I later compute (depthM 9), I just lookup the return value of (depthM 8) and cons it onto null, instead of recursing all the way down to (depthM 0). But then they move the Ns and Rs inside the procedure, and initialize them to null with "let". Why doesn't this completely defeat the point of caching the return values? From a bit of experimentation, it appears that the Ns and Rs are being reinitialized on every call to "depthM". Am I misunderstanding their point? I guess my question is really this: Is there a way in Scheme to have lexically-scoped variables preserve their values in between calls to a procedure, like you can do in Perl 5.10 with "state" variables?

  • Facebook Connect Login redirecting in Chrome and Safari

    - by Lobe
    I am having a problem with Facebook Connect that I can't seem to get my head around. A user clicks on the fb-login button, the pop up appears and they authenticate, the pop up closes and the on-login function is called. This happens in IE and Firefox as is expected. However in Chrome and Safari, the pop up redirects to the canvas url and doesn't close. Also the on-login function isn't called. I have googled and it seems to be something to do with the xd-receiver.htm file, however it seems weird that it is working in IE and Firefox but not Chrome or Safari. Thanks The facebook javascript <script src="http://static.ak.connect.facebook.com/js/api_lib/v0.4/FeatureLoader.js.php/en_US" type="text/javascript"></script> <script type="text/javascript">FB.init("xxxxxxxxxxxxxxxxxx","xd_receiver.htm");</script> And the button <fb:login-button v="2" size="large" onlogin='window.location = "http://www.xxxxxxxxxx.com/development/redirect.php?size=large";'>Connect</fb:login-button> Obviously with Appid and domain hidden. Any ideas? EDIT: After a bit more playing around it turned out that I didn't have my base domain set in Facebook settings. Why it works in some browsers and not others beats me, however it works now. Thanks NSD for your suggestion.

  • Installing Mercurial on Windows Apache XAMPP Tutorial

    - by Tim Dellas
    After asking this question (http://stackoverflow.com/questions/2675764/xampp-mercurial-installation-on-windows-apache-hgwebdir-cgi-script-error) and reading though the whole internet including this question (http://stackoverflow.com/questions/644322/how-do-i-get-mercurials-hgwebdir-working-on-windows) and all its links for about 10 hours, I seem to not be able to find a solution. I begun with this tutorial http://mercurial.selenic.com/wiki/HgWebDirStepByStep ... and I really don't want to install ancient versions of Mercurial. I got my windows-apache to run Python scripts, CGI-Scripts, publish them in the wild, but hgwebdir just won't work. Question 1: Can someone please enrich his personal blog with a tutorial on how to install MERCURIAL on a WINDOWS XAMPP installation and make it visible to the world? I guarantee a lot of pageviews, as this is not a trivial problem. And this would sincerely help a lot of other people I guess. Question 2: For example, even after browsing half a day through everywhere, I just cannot find out, which version of python I need to pair with the freshest version of mercurial, and I get the "magic number is wrong"-error. This would be my question, if noone has time to make up a nice blogpost. Sorry for being a bit frustrated.

  • Django: Serving a Download in a Generic View

    - by TheLizardKing
    So I want to serve a couple of mp3s from a folder in /home/username/music. I didn't think this would be such a big deal but I am a bit confused on how to do it using generic views and my own url. urls.py url(r'^song/(?P<song_id>\d+)/download/$', song_download, name='song_download'), The example I am following is found in the generic view section of the Django documentations: http://docs.djangoproject.com/en/dev/topics/generic-views/ (It's all the way at the bottom) I am not 100% sure on how to tailor this to my needs. Here is my views.py def song_download(request, song_id): song = Song.objects.get(id=song_id) response = object_detail( request, object_id = song_id, mimetype = "audio/mpeg", ) response['Content-Disposition'= "attachment; filename=%s - %s.mp3" % (song.artist, song.title) return response I am actually at a loss of how to convey that I want it to spit out my mp3 instead of what it does now which is to output a .mp3 with all of the current pages html contained. Should my template be my mp3? Do I need to setup apache to serve the files or is Django able to retrieve the mp3 from the filesystem(proper permissions of course) and serve that? If it do need to configure Apache how do I tell Django that? Thanks in advanced. These files are all on the HD so I don't need to "generate" anything on the spot and I'd like to prevent revealing the location of these files if at all possible. A simple /song/1234/download would be fantastic.

  • How can I help fellow students struggling in programming classes?

    - by David Barry
    I'm a computer science student finishing up my second semester of programming classes. I've enjoyed them quite a bit, and learned a lot, but it seems other students are struggling with the concepts and assignments more than I am. When an assignment is due, the inevitable group email comes out the day or two before with people needing some help either with a specific part of the problem, or sometimes people just seem to have a hard time knowing where to start. I'd really like to be able to help out, but I have a hard time thinking of the right way to give them help without giving them the answer. When I'm having trouble understanding a concept, a code snippet can go along way to helping me, but at the same time if it makes a lot of sense, it can be difficult to think of another way to go about it. Plus the Academic Integrity section of each assignment is always looming overhead warning against sharing code with others. I've tried using pseudo code to help give others an idea on program flow, leaving them to figure out how to implement certain aspects of it, but I didn't get too much feedback and don't know how much it actually helped them out, or if it just confused them further. So I'm basically looking to see if anyone has experience with this, or good ways that I can help out other students to nudge them in the right direction or help them think about the problem in the right way.

  • C#, Can I check on a lock without trying to acquire it?

    - by Biff MaGriff
    Hello, I have a lock in my c# web app that prevents users from running the update script once it has started. I was thinking I would put a notification in my master page to let the user know that the data isn't all there yet. Currently I do my locking like so. protected void butRefreshData_Click(object sender, EventArgs e) { Thread t = new Thread(new ParameterizedThreadStart(UpdateDatabase)); t.Start(this); //sleep for a bit to ensure that javascript has a chance to get rendered Thread.Sleep(100); } public static void UpdateDatabase(object con) { if (Monitor.TryEnter(myLock)) { Updater.RepopulateDatabase(); Monitor.Exit(myLock); } else { Common.RegisterStartupScript(con, AlreadyLockedJavaScript); } } And I do not want to do if(Monitor.TryEnter(myLock)) Monitor.Exit(myLock); else //show processing labal As I imagine there is a slight possibility that it might display the notification when it isn't actually running. Is there an alternative I can use? Edit: Hi Everyone, thanks a lot for your suggestions! Unfortunately I couldn't quite get them to work... However I combined the ideas on 2 answers and came up with my own solution.

  • Where to prompt for required file location at start of Win Forms application

    - by Murph
    I have an application that uses a file to store its data. I store the location of the file in the app settings so have two tests at startup: Do I have a setting for the file and Does the file (if I have a setting) exist If I fail either test I want to prompt the user for the file location - the mechanics of the are not the problem, I can read and write the app settings, fire off dialogs and otherwise request the data. If the user refuses to choose a file (or at least a file location) I want to exit the app. My problem is where to do this i.e. at what point in the flow of code. In an ideal world you start the app, show a splash screen, load the main form and run from there... I'm looking for a general pattern that allows me to slot the test for parameters into the right place so that I can prompt the user for whatever (and allowing that I have to worry about the fact that my splash screen is currently topmost for my app). I appreciate that this is a bit vague so will update this with code as we go along.

  • Getting started with workflows in sharepoint 2010

    - by Thomas Stock
    Hi, I'm a beginning sharepoint developer asked to implement the following scenario in sharepoint 2010. We're a bit lost on the best approach to get started.. I'm really struggling to find the best practise solution. This is the flow: A user can make a request with a title and a description. A mail gets sent to the representative with a link to a form. A representative can approve or reject the request. If approved: A mail gets sent to Board with a link to form If rejected: A mail gets sent to the user with the message that it has been rejected. when the request was approved by the representative, the board can approve or reject the request. A mail gets sent to the user and the representative with the descision of the board. So the list has the following fields: Request title Request description Representative approval Representative description Board approval Board description The user should see the following form: Request title (editable) Request description (editable) The representative should see the following form: Request title (read-only) Request description (read-only) Representative approval (editable) Representative description (editable) The Board should see the following form: Request title (read-only) Request description (read-only) Representative approval (read-only) Representative description (read-only) Board approval (editable) Board description (editable) My questions: What tool is most appropriate for making the forms? Infopath? SPD? VS2010? How do I handle rights to make sure only the board can access the board edit form? What kind of workflow do I use? When do I start the workflow(s)? What do I use to develop the workflow(s)? How do I handle rights when showing the listview with all requests? How can I build the links in the mails sent to the different groups. Thanks in advance for any advice.

  • Problems with string parameter insertion into prepared statement

    - by c0d3x
    Hi, I have a database running on an MS SQL Server. My application communicates via JDBC and ODBC with it. Now I try to use prepared statements. When I insert a numeric (Long) parameter everything works fine. When I insert a string parameter it does not work. There is no error message, but an empty result set. WHERE column LIKE ('%' + ? + '%') --inserted "test" -> empty result set WHERE column LIKE ? --inserted "%test%" -> empty result set WHERE column = ? --inserted "test" -> works But I need the LIKE functionality. When I insert the same string directly into the query string (not as a prepared statement parameter) it runs fine. WHERE column LIKE '%test%' It looks a little bit like double quoting for me, but I never used quotes inside a string. I use preparedStatement.setString(int index, String x) for insertion. What is causing this problem? How can I fix it? Thanks in advance.

  • SQL Structure of DB table with different types of columns

    - by Dmitry Dvornikov
    I have a problem with the optimization of the structure of the database. I'll try to explain it exactly. I create a project, where we can add different values??, but this values must have different types of the columns in the database (eg, int, double , varchar). What is the best way to store the different types of values ??in the database. In the project I'm using Propel 1.6. The point is availability to add value with 'int', 'varchar' and other columns types, to search the table was efficient. In total, I have two ideas. The first is to create a table of "value", which will have columns: "id ", "value_int", "value_double", "value_varchar", etc - with the corresponding column types. Depending on the type of values??, records will be saved with the value in the appropriate column (the rest will be NULL). The second solution is to create separate tables such as "value_int", "value_varchar" etc. There would be columns: "id", "value", which correspond to the relevant types of "value" (ie, such as int, varchar, etc). I must admit that I do not believe any of the above solutions, originally I was thinking about one table "value", where the column would be a "text" type - but this solution would probably be even worse. I would like to know your opinion on this topic, maybe something else would be better. Thanks in advance. EDIT: For example : We have three tables: USER: [table of users] * id * name FIELD: [table of profile fields - where the column 'type' is the type of field, eg int or varchar) * id * type * name VALUE : * id * User_id - ( FK user.id ) * Field_id - ( FK field.id ) * value So we have in each row an user in USER table, and the profile is stored in the VALUE table. Bit each profile field may have a different type (column 'type' in the FIELD table), and based on that I would want this value to add to the appropriate column of the appropriate type.

  • Android: ProgressDialog doesn't show

    - by Select0r
    Hi, I'm trying to create a ProgressDialog for an Android-App (just a simple one showing the user that stuff is happening, no buttons or anything) but I can't get it right. I've been through forums and tutorials as well as the Sample-Code that comes with the SDK, but to no avail. This is what I got: btnSubmit.setOnClickListener(new View.OnClickListener() { public void onClick(View view) { (...) ProgressDialog pd = new ProgressDialog(MyApp.this); pd.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL); pd.setMessage("Working..."); pd.setIndeterminate(true); pd.setCancelable(false); // now fetch the results (...long time calculations here...) // remove progress dialog pd.dismiss(); I've also tried adding pd.show(); and messed around with the parameter in new ProgressDialog resulting in nothing at all (except errors that the chosen parameter won't work), meaning: the ProgressDialog won't ever show up. The app just keeps running as if I never added the dialog. I don't know if I'm creating the dialog at the right place, I moved it around a bit but that, too, didnt't help. Maybe I'm in the wrong context? The above code is inside private ViewGroup _createInputForm() in MyApp. Any hint is appreciated, Greetings, Select0r

  • Using the Queue class in Python 2.6

    - by voipme
    Let's assume I'm stuck using Python 2.6, and can't upgrade (even if that would help). I've written a program that uses the Queue class. My producer is a simple directory listing. My consumer threads pull a file from the queue, and do stuff with it. If the file has already been processed, I skip it. The processed list is generated before all of the threads are started, so it isn't empty. Here's some pseudo-code. import Queue, sys, threading processed = [] def consumer(): while True: file = dirlist.get(block=True) if file in processed: print "Ignoring %s" % file else: # do stuff here dirlist.task_done() dirlist = Queue.Queue() for f in os.listdir("/some/dir"): dirlist.put(f) max_threads = 8 for i in range(max_threads): thr = Thread(target=consumer) thr.start() dirlist.join() The strange behavior I'm getting is that if a thread encounters a file that's already been processed, the thread stalls out and waits until the entire program ends. I've done a little bit of testing, and the first 7 threads (assuming 8 is the max) stop, while the 8th thread keeps processing, one file at a time. But, by doing that, I'm losing the entire reason for threading the application. Am I doing something wrong, or is this the expected behavior of the Queue/threading classes in Python 2.6?
