  • Struts2 + jQuery Autocompletion (Solved, with DOJO :) )

    - by Luigi 1982
    I used the jQuery autocompletion for my Struts2 application. Pratically, my action made a list of strings that jQuery use. This is the script: $().ready(function() { $("#tag").autocomplete("/myAction/Action", { multiple : true, autoFill : true, minChars:1 }); }); During typing appear the box with the suggestions. The problem is that the box render another value, exactly render the code of my JSP ( links to CSS for the autocomplete plug-in). How can I solve this? This is my JSP: <html> <head> <script src="<%=request.getContextPath()%>/scripts/jquery-latest.js"></script> <link rel="stylesheet" href="<%=request.getContextPath()%>/scripts/main.css" type="text/css" /> <link rel="stylesheet" href="<%=request.getContextPath()%>/scripts/jquery.autocomplete.css" type="text/css" /> <script type="text/javascript" src="<%=request.getContextPath()%>scripts/jquery.bgiframe.min.js"></script> <script type="text/javascript" src="/<%=request.getContextPath()%>/query.dimensions.js"></script> <script type="text/javascript" src="<%=request.getContextPath()%>/scripts/jquery.autocomplete.js"></script> <script type="text/javascript"> $().ready(function() { $("#tag").autocomplete("/myAction/Action", { multiple : true, autoFill : true, minChars:1 }); }); </script> </head> <body> <s:form action="Action" theme="simple"> <s:iterator value="elencoMateriali" var="asd"> <s:property value="#asd" escape="false"/> </s:iterator> <s:textfield id="tag" name="tagField" label="tag" /> </s:form> </body>

  • Delivery of JMS message before the transaction is committed

    - by ewernli
    Hi, I have a very simple scenario involving a database and a JMS in an application server (Glassfish). The scenario is dead simple: 1. an EJB inserts a row in the database and sends a message. 2. when the message is delivered with an MDB, the row is read and updated. The problem is that sometimes the message is delivered before the insert has been committed in the database. This is actually understandable if we consider the 2 phase commit protocol: 1. prepare JMS 2. prepare database 3. commit JMS 4. ( tiny little gap where message can be delivered before insert has been committed) 5. commit database I've discussed this problem with others, but the answer was always: "Strange, it should work out of the box". My questions are then: How could it work out-of-the box? My scenario sounds fairly simple, why isn't there more people with similar troubles? Am I doing something wrong? Is there a way to solve this issue correctly? Here are a bit more details about my understanding of the problem: This timing issue exist only if the participant are treated in this order. If the 2PC treats the participants in the reverse order (database first then message broker) that should be fine. The problem was randomly happening but completely reproducible. I found no way to control the order of the participants in the distributed transactions in the JTA, JCA and JPA specifications neither in the Glassfish documentation. We could assume they will be enlisted in the distributed transaction according to the order when they are used, but with an ORM such as JPA, it's difficult to know when the data are flushed and when the database connection is really used. Any idea?

  • Scrolling screen upward to expose TextView above keyboard

    - by Matt Winters
    I think I'm missing something obvious and would appreciate an answer. I have a view with a 2-section grouped tableView, each section having one row and a textView, the heights of the rows 335 and 140. This allows for a box with nicely rounded corners to type text into when the keyboard appears (140 height section) and when the keyboard is dismissed, a nice box to read more text (notes); most of the time, use is without the keyboard. I also added a toolbar at the bottom of the screen to scroll up above the keyboard. A button on the toolbar dismisses the keyboard. This last part works fine with the keyboard going up and down using a notification and the following code in a keyboardWillShow method: [UIView beginAnimations:@"showKeyboardAnimation" context:nil]; [UIView setAnimationDuration:0.50]; self.view.frame = CGRectMake(self.view.frame.origin.x, self.view.frame.origin.y, self.view.frame.size.width, self.view.frame.size.height - 216); [UIView commitAnimations]; But with the above code, the 2 sections of the tableView remain unscrolled, only the toolbar and the keyboard move. With the following code (found both in previous posts), both the toolbar and the tableView sections move. [UIView beginAnimations:nil context:NULL]; [UIView setAnimationDuration:0.50]; CGRect rect = self.view.frame; rect.origin.y -= 216; self.view.frame = rect; [UIView commitAnimations]; Now I know that I have to tweak the numbers to get the everything as I want it but my first question is what is substantively different between the 2 sets of code that the sections move in the 2nd but not in the 1st? The toolbar also moves with the 2nd code. The second question is, am I going to be able to scroll the smaller height section from off the screen to above the keyboard while at the same time moving the toolbar up just 216? Thanks

  • Array: mathematical sequence

    - by VaioIsBorn
    An array of integers A[i] (i 1) is defined in the following way: an element A[k] ( k 1) is the smallest number greater than A[k-1] such that the sum of its digits is equal to the sum of the digits of the number 4* A[k-1] . You need to write a program that calculates the N th number in this array based on the given first element A[1] . INPUT: In one line of standard input there are two numbers seperated with a single space: A[1] (1 <= A[1] <= 100) and N (1 <= N <= 10000). OUTPUT: The standard output should only contain a single integer A[N] , the Nth number of the defined sequence. Input: 7 4 Output: 79 Explanation: Elements of the array are as follows: 7, 19, 49, 79... and the 4th element is solution. I tried solving this by coding a separate function that for a given number A[k] calculates the sum of it's digits and finds the smallest number greater than A[k-1] as it says in the problem, but with no success. The first testing failed because of a memory limit, the second testing failed because of a time limit, and now i don't have any possible idea how to solve this. One friend suggested recursion, but i don't know how to set that. Anyone who can help me in any way please write, also suggest some ideas about using recursion/DP for solving this problem. Thanks.

  • WPF Databinding problem

    - by costin
    Hi, I'm new to WPF and I have some difficulties when I'm trying to populate a ListView with a list of custom objects. internal class ApplicationCode { public int Code { get; set; } public IEnumerable<string> InstrumentCodes { get; set; } } I have a list of ApplicationCode which I set to ItemsSource to a ListView. I need to display the ApplicationCode.Code as a string and for the rest of the columns a check box which can be checked/unchecked depending if the column name is contained in the InstrumentCodes collection. In order to set the check box I use a converter on databinding: <DataTemplate x:Key="InstrumentCodeTemplate"> <CheckBox IsEnabled="False" IsChecked="{Binding Mode=OneTime, Converter={StaticResource InstrumentSelectionConverter}}" /> </DataTemplate> The problem I have is because I can't know which is the current column at the time of cell data binding and I can't set the ConverterParameter. public object Convert(object value, Type targetType, object parameter, CultureInfo culture) { ApplicationCode appCode = value as ApplicationCode; return appCode != null && appCode.InstrumentCodes.Contains(parameter.ToString()); } There is a way to find out the column index or name? Or there is another way to solve this problem?

  • How to get the sending email address from outlook 2007

    - by Naresh
    I am working on outlook add-in project using Visual studio 2008 for MS Outlook 2007 in C#. Here I am explaining my problem... I got multiple accounts (3 Accounts) with my outlook 2007. I need to get accounts form Account box in New Mail Message window. When we click New Mail Message, a new window will appear from which we can send a new mail. Here (On this window) we can see Account Dropdown (Left side) under the Send Button. If we have multiple accounts with outlook, we can see all the accounts in Account Drop Down if we click on Account Box. If we click on the particular email, a right mark will appear to that Email Account and a message can bee seen on the top of the Send button is "This message will be sent via [email protected]". So, I want to get these email accounts into a string and that particular email account (which has right mark) into another string. I got these 3 email accounts into a string. But, I am not getting the particular email account(which has the right mark when we send a new email). I am using this code.... using Outlook = Microsoft.Office.Interop.Outlook; using Office = Microsoft.Office.Core; using Microsoft.Office.Interop.Outlook; Outlook._Application myOutlookApp = new Outlook.Application(); Outlook.Accounts myAccounts = myOutlookApp.Session.Accounts; foreach (Outlook.Account account in myAccounts) { string emailAddress = account.SmtpAddress; } I am able to get all the accounts from the above code..But, I just want to get the email address which we will use for sending an email at that particular moment..

  • Zend php memory memory_limit

    - by RepDetec
    All, I am working on a Zend Framework based web application. We keep encountering out of memory errors on our dev server: Allowed memory size of XXXX bytes exhausted (tried YYYY... We keep increasing memory_limit in php.ini, but it is now up over 1000 megs. What is a normal memory_limit value? What are the usual suspects in php/Zend for running out of memory? We are using the Propel ORM. Thanks for all of the help! Update I cannot reproduce this error in my windows environment. If I set memory_limit low (say 16M), I get the same error, but the "tried to allocate" amount is always something reasonable. For example: (tried to allocate 13344 bytes) If I set the memory very low on the (Fedora 9) server (such as 16M), I get the same thing. consistent, reasonable out of memory errors. However, even when the memory limit is set very high on our server (128M, for example), maybe once a week, I will get an crazy huge memory error: (tried to allocate 1846026201 bytes). I don't know if that might shed any more light onto what is going on. We are using propel 1.5. It sounds like the actual release is going to come out later this month, but it doesn't look like anyone else is having this problem with it anyway. I don't know that Propel is the problem. We are using Zend Server with php 5.2 on the Linux box, and 5.3 locally. Any more ideas? I have a ticket out to get Xdebug installed on the Linux box. Thanks, -rep

  • How to organize the work when project needs to be re-implemented due to poor code quality?

    - by Dmitriy Nagirnyak
    Hi, I have joined a very small where one main developer has been buiding the web app (.NET 4.0) during ~6 months. The project should be delivered within next 2 months. After first look at the code I can say that I would never allow it to go to production (things like catch { }, not tests at all with WebForms etc). So the code quality is incredibly low. My task is to improve that and still deliver the solution. So I plan to start with unit testing and MVC2 reimplementing most of the functionality (though using some of the existing code). I estimate that I will need about 6 weeks to catch up with the current progress and be on te same functionality level as the application will be in 6 months. The problem is that the main developer who has been working on the project does not seem to be very 'professional' and skillful (he seems to be really starting in IT and many basic things are unknown to him). It will take significant amount of time and effort to educate him how to do the proper testing, development and apply some patterns. I am ready to take responsibility for the reimplemnting the application but at the same time I don't want the main developer to be on idle but as he won't be able to significantly contribute to the better-world project at this stage I am not sure what would the best way to keep productivity high for both of us. Currently I think following solution is good enough: He proceeds doing what he does until I will catch up with him and then start working on a new project together. The problem is that of course this approach is not very productive as one developer will do better-world project while the other will proceed with what he did, effectively doing similar tasks. Can you suggest how we could better organise the work together in order to be most efficient for the overall project? Thanks, Dmitriy.

  • Cloning items in a listbox c#

    - by Jenny
    I have 2 list boxes and want to be able to copy selected items from one to the other how ever many times I want. Ive managed to do this but I have buttons on the 2nd list box that allow me to go up and down..Now when theres to items in the second list box that are the same (e.g "gills" and "gills") it doesnt behave normally and crashes. Is there a way in which I can get them to act as seperate items in the 2nd listbox? code private void buttonUp_Click(object sender, EventArgs e) { object selected = listBox2.SelectedItem; int index = list2.Items.IndexOf(selected); listBox2.Items.Remove(selected); listBox2.Items.Insert(index - 1, selected); listBox2.SetSelected(index - 1, true); } private void buttonAdd_Click(object sender, EventArgs e) { DataRowView selected = (DataRowView)listBox1.SelectedItem; string item = selected["title"].ToString(); listBox2.Items.Add(item); } It works fine when i havnt got duplicates but when i do they just jump around randomly when i press up/down. (ive not included down as its pretty much the same as up)

  • Should I be relying on WebTests for data validation?

    - by Alexander Kahoun
    I have a suite of web tests created for a web service. I use it for testing a particular input method that updates a SQL Database. The web service doesn't have a way to retrieve the data, that's not its purpose, only to update it. I have a validator that validates the response XML that the web service generates for each request. All that works fine. It was suggested by a teammate that I add data validation so that I check the database to see the data after the initial response validator runs and compare it with what was in the input request. We have a number of services and libraries that are separate from the web service I'm testing that I can use to get the data and compare it. The problem is that when I run the web test the data validation always fails even when the request succeeds. I've tried putting the thread to sleep between the response validation and the data validation but to no avail; It always gets the data from before the response validation. I can set a break point and visually see that the data has been updated in the DB, funny thing is when I step through it in debug with the breakpoint it does validate successfully. Before I get too much more into this issue I have to ask; Is this the purpose of web tests? Should I be able to validate data through service calls in this manner or am I asking too much of a web test and the response validation is as far as I should go?

  • jquery: prepopulating autocomplete fields

    - by David Tildon
    I'm using the tokenizing autocomplete plugin for jquery ( http://loopj.com/2009/04/25/jquery-plugin-tokenizing-autocomplete-text-entry ). I mostly use Ruby, and I'm really unfamiliar with javascript, though. My basic setup looks like this, and works fine for a new, blank form: $(document).ready(function () { $("#tag_ids_field").tokenInput("/tags", { queryParam: "search" }); }); The problem comes when I try to prepopulate it, like for an edit page. I'm trying to do something like this (where the "#tag_ids_field" text box contains the JSON when the page is loaded - that way is just cleaner on the application side of things). $(document).ready(function () { var tags = $("#tag_ids_field").html(); $("#tag_ids_field").tokenInput("/tags", { queryParam: "search", prePopulate: tags }); }); However, when the page loads I see that it's just filled with hundreds of entries that read 'undefined'. I get this even if I take the JSON output that Rails provides and try sticking it right in the .js file: $(document).ready(function () { $("#tag_ids_field").tokenInput("/tags", { queryParam: "search", prePopulate: "[{\"id\":\"44\",\"name\":\"omnis sit impedit et numquam voluptas enim\"},{\"id\":\"515\",\"name\":\"deserunt odit id doloremque reiciendis aliquid qui vel\"},{\"id\":\"943\",\"name\":\"exercitationem numquam possimus quasi iste nisi illum\"}]" }); }); That's obviously not a solution, I just tried it out of frustration and I get the same behavior. My two questions: One, why are my text boxes being filled with "undefined" tags when I try to prepopulate, and how can I get them to prepopulate successfully? Two, I'm planning on having many autocomplete fields like this on the same page (for when several records are edited at once - they all query the same place). How can I make each autocomplete field take it's prepopulated values from it's own textbox? Something like (applying these settings to all input boxes with a certain class, not just the one of a particular id): $(document).ready(function () { $(".tag_ids_field").tokenInput("/tags", { queryParam: "search", prePopulate: (the contents of that particular ".tag_ids_field" input box) }); });

  • Program Structure Design Tools? (Top Down Design)

    - by Lee Olayvar
    I have been looking to expand my methodologies to better involve Unit testing, and i stumbled upon Behavioral Driven Design (Namely Cucumber, and a few others). I am quite intrigued by the concept as i have never been able to properly design top down, only because keeping track of the design gets lost without a decent way to record it. So on that note, in a mostly language agnostic way, are there any useful tools out there i am (probably) unaware of? Eg, i have often been tempted to try building flow charts for my programs, but i am not sure how much that will help, and it seems a bit confusing to me how i could make a complex enough flow chart to handle the logic of a full program, and all its features.. ie, it just seems like flow charts would be limiting in the design scheme.. or possibly grow to an unmaintainable scale. BDD methods are nice, but with a system that is so tied to structure, tying into the language and unit testing seems like a must (for it to be worth it) and it seems to be hard to find something to work well with both Python and Java (my two main languages). So anyway.. on that note, any comments are much appreciated. I have searched around on here and it seems like top down design is a well discussed topic, but i haven't seen too much reference to tools themselves, eg, flow chart programs, etc. I am on Linux, if it matters (in the case of programs).

  • Excel VBA Userform Combobox problem

    - by Marc
    I'm having difficulties with a Combobox in a userform in an Excel document. The combobox either doesn't appear in the userform, or the combobox remains blank, and when I enter any character in it, the list of items appears, but 2 or 3 times, instead of just once. When I select an item, the chosen item doesn't appear in the box. It seems as if Excel^picks one at random, and whichever item I choose from the list, it's always the same one that ends up being displayed in the box. Can anyone help me on this one? Thanks a lot!!! This is the code I used: Private Sub ComboBox1_Change() Select Case ComboBox1.Text Case "Een nieuwe start" Case "Alles heeft zijn tijd" Case "De wereld aan je voeten" Case "Een levend boek" Case "Drempels" Case "Kerstmis" Case "Confituur of choco" Case "Hoe groot is de hemel?" Case "Ongelovige Thomas" Case "Feesten" Case "Er is er één jarig!" Case "Eén van hart" Case "Ervoor gaan" Case "Groen gras" Case "RELatie" Case "Vele plaatjes" Case "Iedereen fan" Case "Schattenjacht" Case "Lichtbakens" Case "Rijke Luis" Case "Hemel op aarde" Case "Op bezoek" Case Else End Select End Sub Private Sub UserForm1_Initialize() ComboBox1.Clear ComboBox1.AddItem "Een nieuwe start" ComboBox1.AddItem "Alles heeft zijn tijd" ComboBox1.AddItem "De wereld aan je voeten" ComboBox1.AddItem "Een levend boek" ComboBox1.AddItem "Drempels" ComboBox1.AddItem "Kerstmis" ComboBox1.AddItem "Confituur of choco" ComboBox1.AddItem "Hoe groot is de hemel?" ComboBox1.AddItem "Ongelovige Thomas" ComboBox1.AddItem "Feesten" ComboBox1.AddItem "Er is er één jarig!" ComboBox1.AddItem "Eén van hart" ComboBox1.AddItem "Ervoor gaan" ComboBox1.AddItem "Groen gras" ComboBox1.AddItem "RELatie" ComboBox1.AddItem "Vele plaatjes" ComboBox1.AddItem "Iedereen fan" ComboBox1.AddItem "Schattenjacht" ComboBox1.AddItem "Lichtbakens" ComboBox1.AddItem "Rijke Luis" ComboBox1.AddItem "Hemel op aarde" ComboBox1.AddItem "Op bezoek" ComboBox1.Text = ComboBox1.List(0) End Sub

  • log4j vs. System.out.println - logger advantages?

    - by wishi_
    Hi! I'm newly using log4j in a project. A fellow programmer told me that using System.out.println is considered bas style and that log4j is something like standard for logging matters nowadays. We do lots of JUnit testing - System.out stuff turns out to be harder to test. Therefore I began utilizing log4j for a Console controller class, that's just handling commandline parameters. // some logger config org.apache.log4j.BasicConfigurator.configure(); Logger logger = LoggerFactory.getLogger(Console.class); Category cat = Category.getRoot(); Seems to work: logger.debug("String"); Produces: 1 [main] DEBUG project.prototype.controller.Console - String I got two questions regarding this: From my basic understanding using this logger should provide me comfortable options to write a logfile with timestamps - instead of spamming the console - if debug mode is enabled at the logger? Why is System.out.println harder to test? I searched stackoverflow and found a testing recipe. So I wonder what kind of advantage I really get by using log4j.

  • WatiN NativeElement.GetElementBounds() - What is the unit of measurement?

    - by Brian Schroer
    When I'm testing with WatiN, I like to save screenshots. Sometimes I don't really need a picture of the whole browser window though - I just want a picture of the element that I'm testing. My attempt to save a picture of an element with the code below resulted in a picture of a block box, because elementBounds.Top points to a pixel position way past the bottom of the screen. The elementBounds.Width and .Height values also appear to be about half what they should be. Is this a WatiN bug, or are these properties in a different unit of measure that I have to convert to pixels somehow? public static void SaveElementScreenshot (WatiN.Core.IE ie, WatiN.Core.Element element, string screenshotPath) { ScrollIntoView(ie, element); ie.BringToFront(); var ieClass = (InternetExplorerClass) ie.InternetExplorer; Rectangle elementBounds = element.NativeElement.GetElementBounds(); int left = ieClass.Left + elementBounds.Left; int top = ieClass.Top + elementBounds.Top; int width = elementBounds.Width; int height = elementBounds.Height; using (var bitmap = new Bitmap(width, height)) { using (Graphics graphics = Graphics.FromImage(bitmap)) { graphics.CopyFromScreen (new Point(left, top), Point.Empty, new Size(width, height)); } bitmap.Save(screenshotPath, ImageFormat.Jpeg); } }

  • Simple .HTACCESS Passing Variables

    - by Willie Murray III
    Let's says I have a classifieds site which has a URL structure similar to the one which I have listed below: Ex. http://takarat.com/openclassifieds/?category=iphone&location=tennessee This is what shows up when I click "tennessee" as the location and then click on "iphone" as the category. Now let's say this site has a search box and I wanted a URL which comes up after using this search box to show up as opposed to the previous URL. Let's say that whenever I search for the word "iphone" while WITHIN the iphone CATEGORY the following link shows up: Iphone SEARCH Ex. http://takarat.com/openclassifieds/?s=iphone&category=iphone&location=tennessee Ok, I want THAT iphone SEARCH to come up whenever anyone clicks Tennessee Iphone..How would I do this [by the way, I want this to be dynamic so that I can use the code for different combinations of locations and products etc..I want the code to use the CATEGORY name to conduct the search basically]? I believe that this will involve "Passing varibles" from the original link... I am new to programming so I may have my terminology wrong. Any help would be appreciated. Thanks in advance.

  • How do I grant a site's applet an AllPermission privilege?

    - by nahsra
    I'd like to specify certain applets to run with java.security.AllPermission on my computer (for debugging and security testing). However, I don't want to enable all applets that I run to have this permission. So, editing my user Java policy file (which I have ensured is the correct policy file through testing), I try to put this value: grant codeBase "http://host_where_applet_lives/-" { permission java.security.AllPermission; }; This value fails when the applet tries to do something powerful (create a new Thread, in my case). However, when I put the following value: grant { permission java.security.AllPermission; }; The applet is able to perform the powerful operation. The only difference is the lack of a codeBase attribute. An answer to a similar question asked here [1] seemed to suggest (but never show or prove) that AccessController.doPrivileged() calls may be required. To me, this sounds wrong as I don't need that call when I grant the permissions to all applets (the second example I showed). Even if this is a solution, littering the applets I run with AccessController.doPrivileged() calls is not easy or necessarily possible. To top it off, my tests show that this just doesn't work anyway. But I'm happy to hear more ideas around it.

  • Formatting inline many-to-many related models presented in django admin

    - by Jonathan
    I've got two django models (simplified): class Product(models.Model): name = models.TextField() price = models.IntegerField() class Invoice(models.Model): company = models.TextField() customer = models.TextField() products = models.ManyToManyField(Product) I would like to see the relevant products as a nice table (of product fields) in an Invoice page in admin and be able to link to the individual respective Product pages. My first thought was using the admin's inline - but django used a select box widget per related Product. This isn't linked to the Product pages, and also as I have thousands of products, and each select box independently downloads all the product names, it quickly becomes unreasonably slow. So I turned to using ModelAdmin.filter_horizontal as suggested here, which used a single instance of a different widget, where you have a list of all Products and another list of related Products and you can add\remove products in the later from the former. This solved the slowness, but it still doesn't show the relevant Product fields, and it ain't linkable. So, what should I do? tweak views? override ModelForms? I Googled around and couldn't find any example of such code...

  • Wordpress Custom Posts

    - by codedude
    I'm having a serious problem with custom post types in Wordpress. I made a post type called "Sermons". I then add a meta box with some text fields and echo out the results onto the web page. But here's my problem. The first time when you add a "Sermon", it works fine and the meta box fields output correctly. However, when I try to edit one of the meta boxes and do not edit the others, (say after I closed the web browser I remembered that I needed to add something to the fields,) the fields that were not edited become blank and the content in them is erased...not good at all. So, just to simplify this: the first time the meta boxes are filled they work fine. However, when editing the post for the second time, the fields that are not filled out, but left as they were, become blank upon saving the post. Help...I'm not too much of a developer so I'm not exactly sure how to fix this...(it was hard enough getting the meta fields to work.) (If you want the actual code used, please tell me and I will add is somewhere.

  • Reconnect to GPRS from J2ME

    - by ouzz
    Dear All, I have a little problem. I have developed a midlet application that call some webservices through internet. I'm using cell phones with GPRS connection. For some time it runs as I wanted, run the apps, call the webservices through the GPRS, it returns the result, call the webservices again, and so on. But say, I call the webservices and after the apps return the result I needed, I left it for a while. The next time I continue to access the webservices, the apps takes a while to connect through the GPRS. In nokia, it is marked with a G in a box. In SE it is marked with a glowing globe. This 'G' in the box or the glowing globe will appear after a while or won't appear at all, but the apps is still trying to connect to the internet. Does it come from my apps or it come from the cell phone? And could I know [or the apps knows] that at the moment the apps tries to connect the GPRS is ready? Thanks a lot for your responses...

  • Version control for PHP Developement

    - by Vinod Mohan
    Hello, I have been hearing a lot about the advantages of using a version control system and would like to try one. I was doing freelance web development in PHP for the past 2 years, two months back I hired two more programmer to help me. I will be hiring one more person soon. We maintain 4 websites, all of which are my own, which are continuously being edited by one of us. I learned PHP by myself and have never worked in any other firms. Hence I am new to version control, unit testing and all. Currently, we have development servers on our workstations. When we edit a particular section of a site, we download the code for that particular section (say /news/ or /movies/ or /wallpapers/ ) from the production server to the dev server, makes the changes locally and uploads to the production server (no code review / testing). Because of this, our dev server is always out of date from our prod server. Occasionally, this also create problem when one of us forgets to download the latest copy from prod and overwrites the last change. I know this is very very foolish, but currently our prod server is the only copy that has all the updates and latest changes. Can anyone please suggest which is the best version control system for me? I am more interested in distributed version control, since we don't have a central backup for all our code. I read about Mercurial and Git and found that Mercurial is used in several large open source projects by Mozilla, Sun, Symbian etc. So which one do you think is better for me? Not only version control, if there are any other package that I can use to make my current setup better, please mention that too :) Thanks and Regards, Vinod Mohan

  • mercurial: how to synchronize mq patches from a master repo as mq patches to a set of clone repos

    - by dim
    I have to run a dozen of different build tests on a code base maintained in a mercurial repository. I don't want to run serially these tests on same repository because they modify a set of common files and I want to run them in parallel on different machines. Also, after all tests are run I want to have access to latest test results from those test work areas. Currently I'm cloning the master repository a dozen of times and run in each clone one different test. Before each test execution I do a pull/update/purge preparation sequence in order to start the test on latest clean state. That's good for me. I'm also preparing new changes using mq extension that I would test on all clones as above before committing them. For testing some ready candidate mq patches I want somehow to deploy/synchronize them to be available in test clones and apply those ready for testing using some guard before running the test. Did anybody do this synchronization before? What's the most simple way to do it? Do I need to have versioned mq patches for that?

  • RadAjaxManager problem when showing/hiding control on page loading

    - by Lukasz Lysik
    I have the webform with dropdown list, label and textbox. Like below: <asp:DropDownList ID="ddlTest" runat="server" AutoPostBack="true"> </asp:DropDownList> <asp:Label ID="lblTest" runat="server" Text="Some text"> </asp:Label> <asp:TextBox ID="edtTest" runat="server"> </asp:TextBox> I want to show/hide label and text box depending on the value selected on dropdown list. So I've added RadAjaxManader: <rad:RadAjaxManager ID="RadAjaxManager1" runat="server"> <AjaxSettings> <rad:AjaxSetting AjaxControlID="ddlTest"> <UpdatedControls> <rad:AjaxUpdatedControl ControlID="lblTest" /> <rad:AjaxUpdatedControl ControlID="edtTest" /> </UpdatedControls> </rad:AjaxSetting> </AjaxSettings> </rad:RadAjaxManager> and procedure "SetupVisibility" which takes value from the dropdown list, does some walidations and desides whether to show or hide the label and the text box. When I use the procedure like this: Protected Sub ddlTest_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles ddlTest.SelectedIndexChanged SetupVisibility() End Sub it works good, but now I want to call SetupVisibility when the page is loaded: Protected Sub Page_Init(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Init SetupVisibility() End Sub The problem occurs in such a scenario: SetupVisibility() hides textbox and label while page is loaded. I change value on ddlTest dropdown list. SetupVisibility() wants to show textbox and label, but then I get the error: Microsoft JScript - runtime error: Cannot update control with ID: ctl00_CPH1_lblTest. The control does not exist. Where is the problem?

  • Objective-C respondsToSelector question.

    - by Holli
    From what I have learned so far: In Objective-C you can send any message to any object. If the object does implement the right method it will be executed otherwise nothing will happen. This is because before the message is send Objective-C will perform respondsToSelector. I hope I am right so far. I did a little program for testing where an action is invoked every time a slider is moved. Also for testing I set the sender to NSButton but in fact it is an NSSlider. Now I asked the object if it will respond to setAlternateTitle. While a NSButton will do and NSSlider will not. If I run the code and do respondsToSelector myself it will tell me the object will not respond to that selector. If I test something else like intValue, it will respond. So my code is fine so far. - (IBAction)sliderDidMove:(id)sender { NSButton *slider = sender; BOOL responds = [slider respondsToSelector:@selector(setAlternateTitle)]; if(responds == YES) { NSLog(@"YES"); } else { NSLog(@"NO"); } [slider setAlternateTitle:@"Hello World"]; } But when I actually send the setAlternateTitle message the program will crash and I am not exactly sure why. Shouldn't it do a respondsToSelector before sending the message?

  • How to Display a Bmp in a RTF control in VB.net

    - by Gerolkae
    I Started with this C# Question I'm trying to Display a bmp image inside a rtf Box for a Bot program I'm making. This function is supposed to convert a bitmap to rtf code whis is inserted to another rtf formatter srtring with additional text. Kind of like Smilies being used in a chat program. For some reason the output of this function gets rejected by the RTF Box and Vanishes completly. I'm not sure if it the way I'm converting the bmp to a Binary string or if its tied in with the header tags 'returns the RTF string representation of our picture Public Shared Function PictureToRTF(ByVal Bmp As Bitmap) As String Dim stream As New MemoryStream() Bmp.Save(stream, System.Drawing.Imaging.ImageFormat.Bmp) Dim bytes As Byte() = stream.ToArray() Dim str As String = BitConverter.ToString(bytes, 0).Replace("-", String.Empty) 'header to string we want to insert Using g As Graphics = Main.CreateGraphics() xDpi = g.DpiX yDpi = g.DpiY End Using Dim _rtf As New StringBuilder() ' Calculate the current width of the image in (0.01)mm Dim picw As Integer = CInt(Math.Round((Bmp.Width / xDpi) * HMM_PER_INCH)) ' Calculate the current height of the image in (0.01)mm Dim pich As Integer = CInt(Math.Round((Bmp.Height / yDpi) * HMM_PER_INCH)) ' Calculate the target width of the image in twips Dim picwgoal As Integer = CInt(Math.Round((Bmp.Width / xDpi) * TWIPS_PER_INCH)) ' Calculate the target height of the image in twips Dim pichgoal As Integer = CInt(Math.Round((Bmp.Height / yDpi) * TWIPS_PER_INCH)) ' Append values to RTF string _rtf.Append("{\pict\wbitmap0") _rtf.Append("\picw") _rtf.Append(Bmp.Width.ToString) ' _rtf.Append(picw.ToString) _rtf.Append("\pich") _rtf.Append(Bmp.Height.ToString) ' _rtf.Append(pich.ToString) _rtf.Append("\wbmbitspixel24\wbmplanes1") _rtf.Append("\wbmwidthbytes40") _rtf.Append("\picwgoal") _rtf.Append(picwgoal.ToString) _rtf.Append("\pichgoal") _rtf.Append(pichgoal.ToString) _rtf.Append("\bin ") _rtf.Append(str.ToLower & "}") Return _rtf.ToString End Function
