  • Recreating http request with cURL incl. files

    - by Toby
    I consistently get the error 'failed creating formpost data' from the below code, the same thing works perfectly on my local testing server, but on my shared host it throws the error. The sample part is just to simulate building the array with both files and non-file data. Essentially all I'm trying to do here is redirect the same http request to another server, but I'm running into so many troubles. $count=count($_FILES['photographs']['tmp_name']); $file_posts=array('samplesample' => 'ladeda'); for($i=0;$i<$count;$i++) { if(!empty($_FILES['photographs']['name'][$i])) { $fn = genRandomString(); $file_posts[$fn] = "@".$_FILES['photographs']['tmp_name'][$i]; } } $ch = curl_init(); curl_setopt($ch,CURLOPT_URL,"http://myurl/wp-content/plugins/autol/rec.php"); curl_setopt($ch,CURLOPT_USERAGENT, "Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)"); curl_setopt($ch,CURLOPT_HEADER,TRUE); curl_setopt($ch,CURLOPT_POST,TRUE); curl_setopt($ch,CURLOPT_POSTFIELDS,$file_posts); curl_exec($ch); print curl_error($ch); curl_close($ch);

  • Can't get jQuery to get focus on cloned input fields

    - by Rebel1Moon
    I have a page that needs to create dynamic form fields as often as the user needs, and I am trying to use Ajax to tie it in to my database for faster form entry and to prevent user typos. So, I have put my Ajax returned data into popup div, the user selects, then the form field is filled in. The problem comes on the cloned fields. They don't seem to want to bring up the popup div when focused. I am thinking it is something to do with when they get created/added to the DOM. Here is my JS that creates the clones: $(document).ready(function() { var regex = /^(.*)(\d)+$/i; var cloneIndex = $(".clonedInput").length; $("button.clone").live("click", function(){ $(this).parents(".clonedInput").clone() .appendTo("#course_container") .attr("id", "clonedInput" + cloneIndex) .find("*").each(function() { var id = this.id || ""; var match = id.match(regex) || []; if (match.length == 3) { this.id = match[1] + (cloneIndex); } }); cloneIndex++; numClones=cloneIndex-1; //alert("numClones "+numClones); }); Here is where I expect to be able to get focus on the correct cloned field and call the popup. The baker_equiv0 id is original code, whereas baker_equiv1 is the first clone. $('#baker_equiv0').focus(function() { \\ THIS CODE WORKS $('.popup').fadeIn(500); $('#results').empty(); // document.enter_data.baker_equiv1.value="test"; THIS LINE WORKS //alert("numClones "+numClones); }); $('#baker_equiv1').focus(function() { // THIS DOESN'T EVER FIRE alert("numClones "+numClones); $('.popup').fadeIn(500); $('#results').empty(); }); Here is the HTML with the form: <label for="baker_equiv" class="">Baker Equivalent: <span class="requiredField">*</span></label> <input type="text" class="cinputsa" name="baker_equiv[]" id="baker_equiv0" size="8" ONKEYUP="get_equiv(this.value);"> If I put this in the HTML code above, it works fine: onfocus="alert(this.id)" I'd also be interested in how to adjust the JS code to work based on the id array created rather than having to copy code for each potential set of fields clones, i.e., baker_equiv[] rather than baker_equiv0, baker_equiv1, etc. Thanks all!

  • Suggest an alternative way to organize/build a database solution.

    - by Hamish Grubijan
    We are using Visual Studio 2010, but this was first conceived with VS2003. I will forward the best suggestions to my team. The current setup almost makes me vomit. It is a C# solution with most projects containing .sql files. Because we support Microsoft, Oracle, and Sybase, and so home-brewed a pre-processor, much like C preprocessor, except that substitutions are performed by a home-brewed C# program without using yacc and tools like that. #ifdefs are used for conditional macro definitions, and yeah - macros are the way this is done. A macro can expand to another macro or two, but this should eventually terminate. Only macros have #ifdef in them - the rest of the SQL-like code just uses these macros. Now, the various configurations: Debug, MNDebug, MNRelease, Release, SQL_APPLY_ALL, SQL_APPLY_MSFT, SQL_APPLY_ORACLE, SQL_APPLY_SYBASE, SQL_BUILD_OUTPUT_ALL, SQL_COMPILE, as well as 2 more. Also: Any CPU, Mixed Platforms, Win32. What drives me nuts is having to configure it correctly as well as choosing the right one out of 12 x 3 = 36 configurations as well as having to substitute database name depending on the type of database: config, main, or gateway. I am thinking that configuration should be reduced to just Debug, Release, and SQL_APPLY. Also, using 0, 1, and 2 seems so 80s ... Finally, I think my intention to build or not to build 3 types of databases for 3 types of vendors should be configured with just a tic tac toe board like: XOX OOX XXX In this case it would mean build MSFT+CONFIG, all SYBASE, and all GATEWAY. Still, the overall thing which uses a text file and a pre-processor and many configurations seems incredibly clunky. It is year 2010 now and someone out there is bound to have a very clean and/or creative tool/solution. The only pro would be that the existing collection of macros has been well tested. Have you ever had to write SQL that would work for several vendors? How did you do it? SqlVars.txt (Every one of 30 users makes a copy of a template and modifies this to suit their needs): // This is the default parameters file and should not be changed. // You can overwrite any of these parameters by copying the appropriate // section to override into SqlVars.txt and providing your own information. //Build types are 0-Config, 1-Main, 2-Gateway BUILD_TYPE=1 REMOVE_COMMENTS=1 // Login information used when applying to a Microsoft SQL server database SQL_APPLY_MSFT_version=SQL2005 SQL_APPLY_MSFT_database=msftdb SQL_APPLY_MSFT_server=ABC SQL_APPLY_MSFT_user=msftusr SQL_APPLY_MSFT_password=msftpwd // Login information used when applying to an Oracle database SQL_APPLY_ORACLE_version=ORACLE10g SQL_APPLY_ORACLE_server=oradb SQL_APPLY_ORACLE_user=orausr SQL_APPLY_ORACLE_password=orapwd // Login information used when applying to a Sybase database SQL_APPLY_SYBASE_version=SYBASE125 SQL_APPLY_SYBASE_database=sybdb SQL_APPLY_SYBASE_server=sybdb SQL_APPLY_SYBASE_user=sybusr SQL_APPLY_SYBASE_password=sybpwd ... (THIS GOES ON)

  • Windows Service Start-Up Error 1069

    - by Gavin
    Hello, I am installing a new windows service coded in C# on a server. I installed the service fine on the server, but once i manually start up the service on a server, with the same login credentials that our other services use, i get the fatal error message notification: "Could not start the %service name% on Local Computer. Error 1069: The Service did not start due to a logon failure." I looked in the event log and i got a 7038 and 7000 event id error in that order. 7038 event id message: "The %service name% service was unable to log on as %login% with the currently configured password due to the following error: Logon failure: unknown user name or bad password. To ensure that the service is configured properly, use the Services snap-in in Microsoft Management Console (MMC)." 7000 event id message: "The %service name% service failed to start due to the following error: The service did not start due to a logon failure. " I have other services that are using the same exact login account and they work fine. Is there something simple I could be missing? Thanks

  • Objective-C Definedness

    - by Dan Ray
    This is an agonizingly rookie question, but here I am learning a new language and framework, and I'm trying to answer the question "What is Truth?" as pertains to Obj-C. I'm trying to lazy-load images across the network. I have a data class called Event that has properties including: @property (nonatomic, retain) UIImage image; @property (nonatomic, retain) UIImage thumbnail; in my AppDelegate, I fetch up a bunch of data about my events (this is an app that shows local arts event listings), and pre-sets each event.image to my default "no-image.png". Then in the UITableViewController where I view these things, I do: if (thisEvent.image == NULL) { NSLog(@"Going for this item's image"); UIImage *tempImage = [UIImage imageWithData:[NSData dataWithContentsOfURL: [NSURL URLWithString: [NSString stringWithFormat: @"http://www.mysite.com/content_elements/%@_image_1.jpg", thisEvent.guid]]]]; thisEvent.image = tempImage; } We never get that NSLog call. Testing thisEvent.image for NULLness isn't the thing. I've tried == nil as well, but that also doesn't work.

  • Expose webservice directly to webclients or keep a thin server-side script layer in between?

    - by max
    Hi, I'm developing a REST webservice (Java, Jersey). The people I'm doing this for want to directly access the webservice via Javascript. Some instinct tells me this is not a good idea, but I cannot really explain that instinct. My natural approach would have been to have the webservice do the real logic and database access, but also have some (relatively thin) server-side script layer (e.g. in PHP). Clients would talk to the PHP layer which in turn would talk to the webservice. (The webservice would be pretty local to the apache/PHP server and implicitly trust calls from the script layer. The script layer would take care of session management.) (Btw, I am not talking about just hiding the webservice behind an Apache which simply redirects calls.) But as I find myself at a lack of words/arguments to explain my instinct, I wonder whether my instinct is right - note that while I have been developing all kinds of software in all kinds of languages and frameworks for like 17 years, this is the first time I develop a webservice. So my question is basically: what are your opinions? Are there any standard setups? Is my instinct totally wrong? Or partially? ;P Many thanks, Max PS: I might add a few bits of information about the planned usage of the whole application: will be accessed by different kinds of users, partly general public, partly privileged thus, all major OS/browser combinations can be expected as clients however, writing the client is not my responsibility will potentially have very high load/traffic logic of webservice will later be massively expanded for another product which is basically a superset of the functionality of the current project there is a significant likelihood that at some point an API should be exposed which can be used by 3rd party developers - obviously, with some restrictions at some point, the public view of the product should become accessible via smartphones, too (in other words, maybe a customized version of the site to adapt to the smaller display and different input methods)

  • Forms blank when rendering a partial when using a collection of objects. Help!

    - by dustmoo
    Alright, I know my title is a little obscure but it best describes the problem I am having. Essentially, I have a list of users, and want to be able to edit their information in-line using AJAX. Since the users are showing up in rows, I am using a partial to render the data and the forms (which will be hidden initially by the ajax), however, when the rows are rendered currently only the last item has it's form's fields populated. I suspect this has something to do with the fact that all the form fields have the same id's and it is confusing the DOM. But I don't know how to make sure the id's are unique. Here is a small example: In my view: <%= render :partial => 'shared/user', :collection => @users %> My partial (broke down to just the form) note that I am using the local variable "user" <% form_for user, :html => {:multipart => true} do |f| -%> <%= f.label :name, "Name*" %> <%= f.text_field :title, :class => "input" %> <%= f.label :Address, "Address" %> <%= f.text_field :address, :class => "input" %> <%= f.label :description, "Description*" %> <%= f.text_area :description, :class => "input" %> <% end -%> When the html is rendered each form has a unique id (for the id of the user) but the elements themselves all have the same id, and only the last user form is actually getting populated with values. Does anyone have any ideas?? :) Thanks in advance!

  • Django templatetag "order of processing"

    - by Jason Persampieri
    I am trying to write a set of template tags that allow you to easily specify js and css files from within the template files themselves. Something along the lines of {% requires global.css %}, and later in the request, {% get_required_css %}. I have this mostly working, but there are a couple of issues. We'll start with the 'timing' issues. Each template tag is made up of two steps, call/init and render. Every call/init happens before any render procedure is called. In order to guarantee that all of the files are queued before the {% get_required_css %} is rendered, I need to build my list of required files in the call/init procedures themselves. So, I need to collect all of the files into one bundle per request. The context dict is obviously the place for this, but unfortunately, the call/init doesn't have access to the context variable. Is this making sense? Anyone see a way around this (without resorting to a hack-y global request object)? Another possibility to store these in a local dict but they would still need to be tied to the request somehow... possibly some sort of {% start_requires %} tag? But I have no clue how to make that work either.

  • Scalable way to store files on server (PHP)?

    - by Nathaniel Bennett
    I'm creating my first web application - a really simplistic online text editor. What I need to do is find the best way to store text based files - a lot of them. These text files can be past 10,000 words in size (text words not computer words.) in essence I want the text documents to be limitless in size. I was thinking about storing the text files in my MySQL database - but thought there was a better way. Instead I'm planing on storing the text files in XML based format in a directory on my server. The rows in the database define the name of the xml based text file and the user who created the text along with basic metadata. An ID is generated using a V4 GUID generator , which gives the text an id and stores the text in the "/store" directory on my server. The text definitions in my server contain this id, and the android app I'm developing gets the contents of the text file by retrieving the text definition and then downloading the text to the local device using the GUID in the text definition. I just think this is a botch job? how can I improve this system? There has been cases of GUID colliding. I don't want this to happen. A "slim" possibility isn't good enough - I need to make sure there is absolutely no chance in a GUID collision. I was planning on checking the database for texts that have the same id before storing the text with a particular id - I however believe with over 20,000 pieces of text in my database this would take an long time and produce unneeded stress on the server. How can I make GUID safe? What happens when a GUID collides? The server backend is going to be written in PHP.

  • git repository sync between computers, when moving around?

    - by Johan
    Hi Let's say that I have a desktop pc and a laptop, and sometimes I work on the desktop and sometimes I work on the laptop. What is the easiest way to move a git repository back and forth? I want the git repositories to be identical, so that I can continue where I left of at the other computer. I would like to make sure that I have the same branches and tags on both of the computers. Thanks Johan Note: I know how to do this with SubVersion, but I'm curious on how this would work with git. If it is easier, I can use a third pc as classical server that the two pc:s can sync against. Note: Both computers are running Linux. Update: So let's try XANI:s idea with a bare git repo on a server, and the push command syntax from KingCrunch. In this example there is two clients and one server. So let's create the server part first. ssh user@server mkdir -p ~/git_test/workspace cd ~/git_test/workspace git --bare init So then from one of the other computers I try to get a copy of the repo with clone: git clone user@server:~/git_test/workspace/ Initialized empty Git repository in /home/user/git_test/repo1/workspace/.git/ warning: You appear to have cloned an empty repository. Then go into that repo and add a file: cd workspace/ echo "test1" > testfile1.txt git add testfile1.txt git commit testfile1.txt -m "Added file testfile1.txt" git push origin master Now the server is updated with testfile1.txt. Anyway, let's see if we can get this file from the other computer. mkdir -p ~/git_test/repo2 cd ~/git_test/repo2 git clone user@server:~/git_test/workspace/ cd workspace/ git pull And now we can see the testfile. At this point we can edit it with some more content and update the server again. echo "test2" >> testfile1.txt git add testfile1.txt git commit -m "Test2" git push origin master Then we go back to the first client and do a git pull to see the updated file. And now I can move back and forth between the two computers, and add a third if I like to.

  • Have a clickable button on top of a combobox in WPF

    - by Travyguy9
    I can get a button to appear and be clickable in the drop down list of a combo box, but I cannot get the selected combo box item (the drop list is closed) to have the button be clickable. It always skips the button click and just opens the drop down list. I basically want the Button_Click event handler that I setup to be called once it is clicked. Here is my sample combo box that shows the button but is not clickable once it is in the selected item: <ComboBox x:Name="MyCombo" Width="200" Height="30" ItemsSource="{Binding ListCombo}"> <ComboBox.Resources> <DataTemplate DataType="{x:Type local:ComboItemClass}"> <StackPanel Orientation="Horizontal"> <TextBlock Text="{Binding Path=SampleText}" Width="120" /> <Button Width="20" Content="..." Click="Button_Click"/> </StackPanel> </DataTemplate> </ComboBox.Resources> </ComboBox>

  • Find telephonenumbers - finding number with and without an phone extension

    - by nWorx
    Hello there I've a table with about 130 000 records with telephonenumbers. The numbers are all formated like this +4311234567. The numbers always include international country code, local area code and then the phonenumber and sometimes an extension. There is a webservice which checks for the caller's number in the table. That service works already. But now the client wants that also if someone calls from a company which number is already in the database but not his extension, that the service will return some result. Example for table. **id** | **telephonenumber** | **name** | 1 | +431234567 | company A | 2 | +431234567890 | employee in company A | 3 | +4398765432 | company b now if somebody from company A calls with a different extension for example +43123456777, than it should return id1. But the problem is, that I don't know how many digits the extensions have. It could have 3,4 or more digits. Are there any patterns for string kind of matchings? The data is stored in a sql2005 database. Thanks

  • How to change database connection without compiling, using JBoss Seam?

    - by MLB
    Hi there: I am developing a web site in Eclipse using JBoss Seam 1.2. My site uses a database (named ALregcli) hosted in a MySQL server. That database has only one table named trazasfallos. The server I am using is local (localhost). When I deploy the site in an "X HOST", the MySQL server it is not in the same computer... the server is in an "Y HOST", so, the connection will not be stablished to the database. I was changing the Context.xml, but it didn't work. The only way it worked was changing the host to connect to in the Context.xml and "recompiling" all the project. Then, it generates the new version of the compiled class trazasfallos.class, and this is the file I have to overwrite for connecting to a new database server. The point is that I want to make the change without "recompiling" anything... Maybe there is a way to make only a "text change" and it will work (maybe in a .xml file)... but I don't know how to do it!! The question is: how to change the connection to the database without recompiling anything in the site?? I am sorry about my English, I am from Cuba.

  • Unable to access index for repository error?

    - by Tommy O'Dell
    I've just created a package (RTIO) and a package repository (Q:/Integrated Planning/R), which is a company network drive. I've put my package into the folder: Q:/Integrated Planning/R/bin/windows/contrib/2.15.1/RTIO_0.1-2.zip As per Dirk's instructions in this SO, I've run the following commands: > setwd("Q:/Integrated Planning/R/bin/windows/contrib/2.15.1") > tools::write_PACKAGES(".", type="win.binary") > list.files() [1] "PACKAGES" "PACKAGES.gz" "RTIO_0.1-2.zip" > With the code below, I've added the local repository to my list of repos (and I'll get other users to do the same): options(repos = c(getOption("repos"), RioTintoIronOre = "Q:/Integrated Planning/R")) And now trying to install my package I get an error: > install.packages("RTIO") Installing package(s) into ‘C:/Program Files/R/R-2.15.1/library’ (as ‘lib’ is unspecified) Warning in install.packages : unable to access index for repository Q:/Integrated Planning/R/bin/windows/contrib/2.15 Warning in install.packages : unable to access index for repository Q:/Integrated Planning/R/bin/windows/contrib/2.15 Warning in install.packages : unable to access index for repository Q:/Integrated Planning/R/bin/windows/contrib/2.15 Warning in install.packages : package ‘RTIO’ is not available (for R version 2.15.1) What does unable to access index for repository tell me? And how can I fix it? What I'm really looking to do is to do, under Windows and with RStudio as the IDE, is to let other internal R users add this package repo such that they're able to run commands like install.packages("RTIO") or update.packages() (and presumably use the IDE to manage packages via the GUI)?

  • Eror while showing returned value on parent window from chield (Dialog box) window using JSF Trinida

    - by Navnath
    Hi There, I am using Myfaces and Trinidad tld's for page design. In that, I am trying to implement Dialog box which will going to open on button click with tacking some value from parent window and return result to Parent window. Now the problem is I can send value to Dialog box and also get return from dialog box successfully, but there is problem to show return value on Parent window because parent window is not reflecting that value and ask for refresh page. When I refresh page, it again open the pop up, i.e. it resending the previous request. Here is my return code. private UIXInput input; public UIXInput getInput() { return input; } public void setInput(UIXInput input) { this.input = input; } public void returned(ReturnEvent event) { if (event.getReturnValue() != null) { getInput().setValue(event.getReturnValue()); RequestContext afContext = RequestContext.getCurrentInstance(); afContext.addPartialTarget(getInput()); } } Next is I have bind input variable with field which need to reflect return value. Here is .jspx code. I have download Trinidad dialog code and try to run on local system, but it not showing any dialog box. But once I remove partialSubmit="true" attribute from comment button which shows dialog box, Then I can see dialog box. Is this attribute making an above error? I hope I have explain my problem clearly. Please...Please let me know any any kind of solution, suggestion. I have spend almost a week to resolve this issue, but.......didn't succeed. Thank You in advance, Navnath Kumbhar.

  • JQM dialog is opening in new page instead of dialog

    - by K D
    Thank you for taking the time to read my question. I'm trying to get a dialog box to open using Jquery mobile. I followed the documentation and used the data-rel="dialog" notation along with the data-transition="pop". Instead of a dialog appearing on the same page, I get a brand new page with the dialog appearing. Can someone kindly assist me on how to fix this functionality. Here is my code for the initial main page: <article> <ul data-role="listview" data-split-icon="star" data-split-theme="d" data-inset="true"> <li><a href="#black_seed_desc" data-rel="dialog" ><img src="black_seed.jpg"/> <h3>Black Seed Oil</h3> </a> <a href="#black_seed_purchase" data-rel="dialog" data-transition="pop">Purchase Black Seed Oil</a> </li> </ul> </article> Here is my code for the dialog page: <div data-role="dialog" id="black_seed_purchase" data-theme="c"> <section data-role="content"> <h1>Purchase Black Seed Oil?</h1> <p>By purchasing Black Seed Oil you will receive an email receipt copy sent to you for your reference.</p> <a href="#purchase_blackseed" data-inline="true" data-corners="true" data-rel="back" data-role="button" data-shadow="true" data-iconshadow="true" data-wrapperrels="span"> <span> <span>Buy: $49.99</span> <span>&nbsp;</span> </span> </a> <a href="#" data-role="button" data-rel="back" data-inline="true" data-corners="true" data-wrapperrels="span" data-shadow="true" data-iconshawdow="true"> <span> Cancel </span> </a> </section> </div> Here is a working example. http://jsfiddle.net/Gajotres/w3ptm/?

  • Sending Email to a specific address without requiring user to specify their mail server details

    - by sgmoore
    Can anyone recommend a simple and reliable method of sending email notifications and possibly log files attachments from a C# program without requiring the installer or the user to configure the program by specifying server details and email addresses etc. (Mainly because they won't know the details, but also because they could change) The program will normally be run as a service of a Windows Server, but can be run on a client. I tried connecting to our own mail server and sending a email to myself, but some ISP's are blocking Port 25 on all servers but their own, so that method isn't working reliably. Tried sending email through gmail but that was less successful as the port they used was blocked by firewalls. Ditto webservices connecting on weird ports. Trying to use the local smptservice but did not work either. It would be nice, but not essential if it was not dependant on my own Internet connection/Servers. (Don't mind them being delayed, but prefer them not to get lost). Are there any webservices on http/https that allow you to do this sort of thing? TIA

  • Sorting a list of numbers with modified cost

    - by David
    First, this was one of the four problems we had to solve in a project last year and I couldn’t find a suitable algorithm so we handle in a brute force solution. Problem: The numbers are in a list that is not sorted and supports only one type of operation. The operation is defined as follows: Given a position i and a position j the operation moves the number at position i to position j without altering the relative order of the other numbers. If i j, the positions of the numbers between positions j and i - 1 increment by 1, otherwise if i < j the positions of the numbers between positions i+1 and j decreases by 1. This operation requires i steps to find a number to move and j steps to locate the position to which you want to move it. Then the number of steps required to move a number of position i to position j is i+j. We need to design an algorithm that given a list of numbers, determine the optimal (in terms of cost) sequence of moves to rearrange the sequence. Attempts: Part of our investigation was around NP-Completeness, we make it a decision problem and try to find a suitable transformation to any of the problems listed in Garey and Johnson’s book: Computers and Intractability with no results. There is also no direct reference (from our point of view) to this kind of variation in Donald E. Knuth’s book: The art of Computer Programing Vol. 3 Sorting and Searching. We also analyzed algorithms to sort linked lists but none of them gives a good idea to find de optimal sequence of movements. Note that the idea is not to find an algorithm that orders the sequence, but one to tell me the optimal sequence of movements in terms of cost that organizes the sequence, you can make a copy and sort it to analyze the final position of the elements if you want, in fact we may assume that the list contains the numbers from 1 to n, so we know where we want to put each number, we are just concerned with minimizing the total cost of the steps. We tested several greedy approaches but all of them failed, divide and conquer sorting algorithms can’t be used because they swap with no cost portions of the list and our dynamic programing approaches had to consider many cases. The brute force recursive algorithm takes all the possible combinations of movements from i to j and then again all the possible moments of the rest of the element’s, at the end it returns the sequence with less total cost that sorted the list, as you can imagine the cost of this algorithm is brutal and makes it impracticable for more than 8 elements. Our observations: n movements is not necessarily cheaper than n+1 movements (unlike swaps in arrays that are O(1)). There are basically two ways of moving one element from position i to j: one is to move it directly and the other is to move other elements around i in a way that it reaches the position j. At most you make n-1 movements (the untouched element reaches its position alone). If it is the optimal sequence of movements then you didn’t move the same element twice.

  • When may I ask a question to fellow developers? (Rules before asking questions).

    - by Zwei Steinen
    I assigned a quite simple task to one junior developer today, and he kept pinging me EVERY 5 minutes for HOURS, asking STEP BY STEP, what to do. Whenever something went wrong, he simply copy&pasted the log and basically wrote, "An exception occurred. What should I do?" So I finally had to tell him, "If you want to be a developer, please start thinking a little bit. Read the error message. That's what they are for!". I also however, tell junior developers to ask questions before spending too much time trying to solve it themselves. This might sound contradictory, but I feel there is some kind of an implicit rule that distinguishes questions that should be asked fairly quickly and that should not (and I try to follow those rules when I ask questions..) So my question is, do you have any rules that you follow, or expect others to follow on asking questions? If so, what are they? Let me start with my own. If you have struggled for more than 90 min, you may ask that question (exceptions exists). If you haven't struggled for more than 15 min, you may not ask that question (if you are sure that the answer can not be found within 15 min, this rule does not have to apply). If it is completely out of your domain and you do not plan to learn that domain, you may ask that question after 15 min (e.g. if I am a java programmer and need to back up the DB, I may ask the DBA what procedure to follow after googling for 15 min). If it is a "local" question, whose answer is difficult to derive or for which resources is difficult to get (e.g. asking an colleague "what method xxx does" etc.), you may ask that question after 15 min. If the answer for it is difficult to derive, and you know that the other person knows the answer, you may ask the question after 15 min (e.g. asking a hibernate expert "What do I need to change else to make this work?". If the process to derive the answer is interesting and is a good learning opportunity, you may ask for hints but you may not ask for answers! What are your rules?

  • Silverlight logging out causes "Object reference not set to an instance"

    - by Alex
    I am using the Silverlight 4 Business Application Template. I've created a DomainDataSource in XAML like so: <riaControls:DomainDataSource x:Name="LogData" QueryName="GetLogs" AutoLoad="True" LoadSize="20" > <riaControls:DomainDataSource.DomainContext> <local:AdminDomainContext /> </riaControls:DomainDataSource.DomainContext> <riaControls:DomainDataSource.QueryParameters> <riaControls:Parameter ParameterName="UserLoginID" Value="{Binding Path=User.UserLoginID, Source={StaticResource WebContext}}" /> </riaControls:DomainDataSource.QueryParameters> </riaControls:DomainDataSource> The problem I'm experiencing is that whenever I log out, I get: Load operation failed for query 'GetLogs'. Object reference not set to an instance of an object. I assume that because I've logged out, User.UserLoginID is now null and is causing the exception. So... anybody know a good way for me to solve this? I don't really want to set the QueryParameter programmatically.

  • queued view updates not happening when performSelector afterDelay:0 used

    - by JosephH
    Hi all, I have an app that performs some calculations based on data arriving on a socket or local user interaction. I want to show an 'activity spinner' whilst the calculation happens. spinner = [[UIActivityIndiactorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhiteLarge]; [spinner setCenter:self.view.center]; [self.view addSubview:spinner]; [spinner startAnimating]; [self performSelector:@selector(doCalcs) withObject:nil afterDelay:0]; This works well, except in the case where the code is run as a result of a message arriving over the network. I'm using http://code.google.com/p/cocoaasyncsocket/ to handle sockets and the code is running in the onSocket:didReadData:withTag: method. 'doCalcs' takes a few seconds. The spinner doesn't appear whilst it's running. If I change afterDelay:0 to afterDelay:1 then the spinner does appear the whole time doCalcs is running, but with the downside that it takes an extra second. So it seems the code is all correct, but for whatever reason the spinner isn't getting a chance to get on screen before doCalcs runs. Any suggestions would be most welcome.

  • â?? in my hmtl after purify

    - by mmcgrail
    I have a database the i am rebuilding the table structure was crap so I'm porting some of the data from one table to another. This data appears to have been copy past from MSO product so as I'm getting the data I clean it up with htmlpurifier and some alittle str_replace in php here the clean function function clean_html($html) { $config = HTMLPurifier_Config::createDefault(); $config->set('AutoFormat','RemoveEmpty',true); $config->set('HTML','AllowedAttributes','href,src'); $config->set('HTML','AllowedElements','p,em,strong,a,ul,li,ol,img'); $purifier = new HTMLPurifier($config); $html = $purifier->purify($html); $html = str_replace('&nbsp;',' ',$html); $html = str_replace("\r",'',$html); $html = str_replace("\n",'',$html); $html = str_replace("\t",'',$html); $html = str_replace(' ',' ',$html); $html = str_replace('<p> </p>','',$html); $html = str_replace(chr(160),' ',$html); return trim($html); } but when I put the results into my new table and out put them to the ckeditor I get those three characters. I then have a javascript function that is called to remove special characters from the content of the ckeditor too. it doesn't clean it either function remove_special(str) { var rExps=[ /[\xC0-\xC2]/g, /[\xE0-\xE2]/g, /[\xC8-\xCA]/g, /[\xE8-\xEB]/g, /[\xCC-\xCE]/g, /[\xEC-\xEE]/g, /[\xD2-\xD4]/g, /[\xF2-\xF4]/g, /[\xD9-\xDB]/g, /[\xF9-\xFB]/g, /\xD1/,/\xF1/g, "/[\u00a0|\u1680|[\u2000-\u2009]|u200a|\u200b|\u2028|\u2029|\u202f|\u205f|\u3000|\xa0]/g", /\u000b/g,'/[\u180e|\u000c]/g', /\u2013/g, /\u2014/g, /\xa9/g,/\xae/g,/\xb7/g,/\u2018/g,/\u2019/g,/\u201c/g,/\u201d/g,/\u2026/g]; var repChar=['A','a','E','e','I','i','O','o','U','u','N','n',' ','\t','','-','--','(c)','(r)','*',"'","'",'"','"','...']; for(var i=0; i<rExps.length; i++) { str=str.replace(rExps[i],repChar[i]); } for (var x = 0; x < str.length; x++) { charcode = str.charCodeAt(x); if ((charcode < 32 || charcode > 126) && charcode !=10 && charcode != 13) { str = str.replace(str.charAt(x), ""); } } return str; } Does anyone know off hand what I need to do to get rid of them. I think they may be some sort of quote

  • Zend dubugger in eclipse - timeout everytime

    - by jax
    I am running a virtual server in the US. I am trying to get my eclipse machine at home (outside the USA), to connect to the USA server. I have setup Zend on the server. When I run phpinfo() I get the following zend output. Note: 1.2.3.4 will be the external WAN IP address of my ADSL router at home. Directive Local Value Master Value zend_debugger.allow_hosts 127.0.0.1,1.2.3.4 127.0.0.1,1.2.3.4 zend_debugger.allow_tunnel no value no value zend_debugger.deny_hosts no value no value zend_debugger.expose_remotely always always zend_debugger.httpd_uid -1 -1 zend_debugger.max_msg_size 2097152 2097152 zend_debugger.tunnel_max_port 65535 65535 zend_debugger.tunnel_min_port 1024 1024 So zend looks like it is working ok on the server side. When I run a debug session and select 'Test Debugger' I get a timeout every time. I have already added dummy.php to the root folder of the server. In 'installed debuggers' I double clicked on Zend and have put my external WAN IP address. I noticed that the port is 10000, I also have webmin running on this port on the server, will there be a conflict?

  • Am I doing something wrong here (references in C++)?

    - by m4design
    I've been playing around with references (I'm still having issues in this regard). 1- I would like to know if this is an acceptable code: int & foo(int &y) { return y; // is this wrong? } int main() { int x = 0; cout << foo(x) << endl; foo(x) = 9; // is this wrong? cout << x << endl; return 0; } 2- Also this is from an exam sample: Week & Week::highestSalesWeek(Week aYear[52]) { Week max = aYear[0]; for(int i = 1; i < 52; i++) { if (aYear[i].getSales() > max.getSales()) max = aYear[i]; } return max; } It asks about the mistake in this code, also how to fix it. My guess is that it return a local reference. The fix is: Week & max = aYear[0]; Is this correct/enough?

  • Newbie - eclipse workflow (PHP development)

    - by engil
    Hi all - this is a bit of a newbie question but hoping I can get some guidance. I've been playing around with Eclipse for a couple months yet I'm still not completely comfortable with my setup and it seems like every time I install it to a new system I end up with different results. What I'm hoping to achieve is (I think) fairly standard. In my environment I'd like SVN (currently using Subclipse), FTP support (currently using Aptana plugin), debugging (going to use XDebug) and all the usual bells and whistles of development (code completion, refactoring, etc.) My biggest current issue is how to set up my environment to support both a 'development' and 'production' server. Optimally I would be able to work directly against the dev server (Eclipse on my Vista desktop against the VM Ubuntu dev server) and then push to production server (shared hosting). I'd prefer to work directly against the dev server (with no local project files, just using the Connections provided by Aptana) but I'm guessing this won't allow for code-completoin or all the other bells and whistles provided for development. Any thoughts? Kind of an open ended question, but maybe this could be an opportunity for some of you with a great deal of experience using Eclipse to describe your setups so people like me can get some insight into good ways to get set up.
