• Weird Issues with WPMU I Can't Figure Out

  - by HollerTrain

  I know I should post this on the WPMU forum, but no one writes me back and I'm just trying to find a larger audience hoping you have run into this issue as well. I have built a WPMU site for a client, and I am able to upload media into the Media Library and within a Post or Page perfectly. I thought my job was finished, yet the client can't upload any media at all. I'm located in Kentucky, they are located in New England (if that even matters). I had the client record their process of uploading as I thought they were simply not following my instructions for uploading, yet they are doing everything correctly. When uploading a file it goes through the process of allowing them to select a file and it says it uploads it, yet when it is finished uploading nothing is in the Media Library or in the Post. Video of the client trying to upload in Media Manager (http://www.screencast.com/users/CatherineWeber/folders/Jing/media/945d33fa-a752-45fd-9bc1-f76fc5a1814a) Video of the client trying to upload within a Post (http://www.screencast.com/users/CatherineWeber/folders/Jing/media/b5c60e25-f0b5-40c0-a820-c2fc9eb00906) Asking the client to disable Flash Uploader didn't work :( Yet, I can login to the WPMU site, access their blog's backend and can easily upload a ton of files. I am so lost at to what the issue is here. I am running version 2.8.4a, and will try to upgrade to latest release hoping this will fix things.

• lnk2019 error in very simple c++ program

  - by Erin

  I have tried removing various parts and building, but nothing makes the lnk2019 error go away, or even produces any normal errors. Everything is in the one file at the moment (it won't be later when it is finished). The program has three lists of words and makes a jargon phrase out of them, and you are supposed to be able to add words, remove words, view the lists, restore defaults, save changes to file, and load changes from file. #include "stdafx.h" #include <iostream> #include <string.h> using namespace std; const int maxlist = 20; string adj1[maxlist], adj2[maxlist], noun[maxlist]; void defaultlist(int list) { if(list == 1) { adj1[0] = "green"; adj1[1] = "red"; adj1[2] = "yellow"; adj1[3] = "blue"; adj1[4] = "purple"; int i = 5; while(i != maxlist) { adj1[i] = ""; i = i + 1; } } if(list == 2) { adj2[0] = "shiny"; adj2[1] = "hard"; adj2[2] = "soft"; adj2[3] = "spiky"; adj2[4] = "furry"; int i = 5; while(i != maxlist) { adj2[i] = ""; i = i + 1; } } if(list == 3) { noun[0] = "cat"; noun[1] = "dog"; noun[2] = "desk"; noun[3] = "chair"; noun[4] = "door"; int i = 5; while(i != maxlist) { noun[i] = ""; i = i + 1; } } return; } void printlist(int list) { if(list == 1) { int i = 0; while(!(i == maxlist)) { cout << adj1[i] << endl; i = i + 1; } } if(list == 2) { int i = 0; while(!(i == maxlist)) { cout << adj2[i] << endl; i = i + 1; } } if(list == 3) { int i = 0; while(!(i == maxlist)) { cout << noun[i] << endl; i = i + 1; } } return; } string makephrase() { int num1 = rand()%maxlist; int num2 = rand()%maxlist; int num3 = rand()%maxlist; int num4 = rand()%1; string word1, word2, word3; if(num4 = 0) { word1 = adj1[num1]; word2 = adj2[num2]; } else { word1 = adj2[num1]; word2 = adj1[num2]; } word3 = noun[num3]; return word1 + " ," + word2 + " " + word3; } string addword(string word, int list) { string result; if(list == 1) { int i = 0; while(!(adj1[i] == "" || i == maxlist)) { i = i + 1; } if(i == maxlist) result = "List is full.

• exception message getting lost in IIOP between glassfish domains

  - by Michael Borgwardt

  I'm running two glassfish v2 domains containing stateless session EJBs. In a few cases, an EJB in one domain has to call one in the other. My problem is that when the called EJB aborts with an exception, the caller does not receive the message of the exception and instead reports an internal error that is not helpful at all in diagnosing the problem. What happens seems to be this: At the transport layer, a org.omg.CORBA.portable.ApplicationException is created,which already loses all detail information about the exception except its class. Inside com.sun.jts.CosTransactions.TopCoordinator.get_txcontext(), the status of the transaction ass rolled back causes a org.omg.CosTransactions.Unavailable to be thrown, which gets wrapped and passed around a few times and eventually results into this error being displayed to the user: org.omg.CORBA.INVALID_TRANSACTION: vmcid: 0x0 minor code: 0 completed: No at com.sun.jts.CosTransactions.CurrentTransaction.sendingRequest(CurrentTransaction.java:807) at com.sun.jts.CosTransactions.SenderReceiver.sending_request(SenderReceiver.java:139) at com.sun.jts.pi.InterceptorImpl.send_request(InterceptorImpl.java:344) at com.sun.corba.ee.impl.interceptors.InterceptorInvoker.invokeClientInterceptorStartingPoint(InterceptorInvoker.java:271) at com.sun.corba.ee.impl.interceptors.PIHandlerImpl.invokeClientPIStartingPoint(PIHandlerImpl.java:348) at com.sun.corba.ee.impl.protocol.CorbaClientRequestDispatcherImpl.beginRequest(CorbaClientRequestDispatcherImpl.java:284) at com.sun.corba.ee.impl.protocol.CorbaClientDelegateImpl.request(CorbaClientDelegateImpl.java:184) at com.sun.corba.ee.impl.presentation.rmi.StubInvocationHandlerImpl.privateInvoke(StubInvocationHandlerImpl.java:186) at com.sun.corba.ee.impl.presentation.rmi.StubInvocationHandlerImpl.invoke(StubInvocationHandlerImpl.java:152) at com.sun.corba.ee.impl.presentation.rmi.bcel.BCELStubBase.invoke(BCELStubBase.java:225) Is there anything I can do here to preserve information about the actual cause of the problem?

• Parsing a blackberry .ipd file

  - by galaxywatcher

  I recently lost my Blackberry. When I discovered it was gone very shortly afterwards and called it, the sim card had already been removed. I ain't seeing that Blackberry again. Ok. I am out $300, but at least my data is backed up. I had an older working Blackberry fortunately and I got a new sim card and proceeded to restore my data using Blackberry Desktop Manager. 7000+ emails, hundreds of autotext entries, sms messages, calendar events, all backing up. Looking good. Lo and behold! My Address Book contacts refuse to back up? I try advanced, and it is greyed out as an option to restore. Far more frustrating than losing my bberry in the first place is wrangling with software that defies human logic. Ok, now I guess I will have to enter all 327 names by hand. That is, if I can read the .ipd file. I have tried the free version of ABC Amber Blackberry editor, but when I open the .ipd file, the contacts just do not show up. I am beginning to feel like the gods are conspiring against me. Then I found this: http://jabide.com/2009/03/parse-blackberry-ipd-files/ He posted a perl script that claims to extract the files. I copied and pasted the code and it did list all the different databases in my .ipd file, I was elated that a cool solution like this was published. I followed the instructions and garbled data with some discernible ascii was sent to standard output unlike a .csv file like he said it would. This is enough to make a grown man cry. Does anyone out there have a solution to extract my address book contacts from an .ipd file?

• How do I improve this design for dealing with intersecting date ranges and resolving date range conf

  - by derdo

  I am working on some code that deals with date ranges. I have pricing activities that have a starting-date and an end-date to set a certain price for that range. There are multiple pricing activities with intersecting date ranges. What I ultimately need is the ability to query valid prices for a date range. I pass in (jan1,jan31) and I get back a list that says jan1--jan10 $4 , jan11--jan19 $3 jan20--jan31 $4. There are priorities between pricing activities. Some type of pricing activities have high priority, so they override other pricing activities and for certain type of pricing activities lowest price wins etc. I currently have a class that holds these pricing activities and keeps a resolved pricing calendar. As I add new pricing activities I update the resolved calendar. As I write more tests/code, it started to get very complicated with all the different cases (pricing activities intersecting in different ways). I am ending up with very complicated code where I am resolving a newly added pricing activity. See AddPricingActivity() method below. Can anybody think of a simpler way to deal with this? Could there be similar code somewhere out there? Public class PricingActivity() { DateTime startDate; DateTime endDate; Double price; Public bool StartsBeforeEndsAfter (PricingActivity pAct) { // pAct covers this pricing activity } Public bool StartsMiddleEndsAfter (PricingActivity pAct){ // early part of pAct Itersects with later part of this pricing activity } //more similar methods to cover all the combinations of intersecting } Public Class PricingActivityList() { List<PricingActivity> activities; SortedDictionary<Date, PricingActivity> resolvedPricingCalendar; Public void AddPricingActivity(PricingActivity pAct) { //update the resolvedCalendar //go over each activity and find intersecting ones //update the resolved calendar correctly //depending on the type of the intersection //this part is getting out of hand….. } }

• How to run R through PHP with exec?

  - by dkar

  I am going to ask something, that I know that it has been asked already some times. But since, all of the past posts are quite old and none of them answer my problem..I try again. I am completely new in R language and relative new in php. What I want to do is to use the exec() function from php in order to execute a R script. Most of the people here will start talking about rapache, rserve and I don't know what else..but since I am not familiar with all these technologies, I prefer just using exec. The code I will show here is working just fine when I run it with Rscript from the terminal. # R script png("temp.png") plot(5,5) dev.off() But when I try to run it either with Rscript or with R CMD BATCH from PHP, like this: echo exec("Rscript my_rscript.R"); //OR //echo exec("R CMD BATCH my_rscript.R"); I get nothing back. I have checked if exec() function is available and if it works. Everything is ok with this. I read also, that I might have to change the permissions of the webserver...but I don't know how to do this in mamp. I hope I am clear with my problem and someone can help. Thanks Dimitris

• Understanding Hibernate saveOrUpdate

  - by Stephano

  The books that I've read regarding hibernate are, at best, reference tomes. They very seldom have good code examples, so I tend to use online resources for those needs. However, I've always had a problem understanding the basic idea of hibernate persistence. I've read the books and understand the concepts, but in practice, I often see results that I don't understand. Perhaps you all can help, as you have in the past. Let's look at a simple example of a dog and a cat that are friends. This isn't a rare occurrence. It also has the benefit of being much more interesting than my business case. We want a function called "saveFriends" that takes a dog name and a cat name. We'll save the Dog and then the Cat. For this example to work, the cat is going to have a reference back to the dog. I understand this isn't an ideal example, but it's cute and works for our purposes. FriendService.java public int saveFriends(String dogName, String catName) { Dog fido = new Dog(); Cat felix = new Cat(); fido.name = dogName; fido = animalDao.saveDog(fido); felix.name = catName; [ex.A]felix.friend = fido; [ex.B]felix.friend = animalDao.getDogByName(dogName); animalDao.saveCat(felix); } AnimalDao.java (extends HibernateDaoSupport) public Dog saveDog(Dog dog) { getHibernateTemplate().saveOrUpdate(dog); return dog } public Cat saveCat(Cat cat) { getHibernateTemplate().saveOrUpdate(cat); return cat; } public Dog getDogByName(String name) { return (Dog) getHibernateTemplate().find("from Dog where name=?", name).get(0); } Now, assume for a minute that I would like to use either example A or example B to save my friend. Is one better than the other to use? I'll understand if neither of those examples work, but please explain why.

• Why are changes to coffeescript files not being compiled when my Rails 3.2.0 app is in development mode?

  - by ben

  Normally, any changes I make to .js.coffee files in my Rails 3.2.0 app in development mode take effect when I refresh the page. All of a sudden, this is not happening. If I do rake assets:precompile, then the changes are shown, but then if I do rake assets:clean they go back to not being shown. What is causing this? Edit: Restarting the server makes the changes show. Why isn't this happening automatically as before? Edit: Here is my development.rb Myapp::Application.configure do # Settings specified here will take precedence over those in config/application.rb # In the development environment your application's code is reloaded on # every request. This slows down response time but is perfect for development # since you don't have to restart the web server when you make code changes. config.cache_classes = false # Log error messages when you accidentally call methods on nil. config.whiny_nils = true # Show full error reports and disable caching config.consider_all_requests_local = true config.action_controller.perform_caching = false # Don't care if the mailer can't send config.action_mailer.raise_delivery_errors = false # Print deprecation notices to the Rails logger config.active_support.deprecation = :log # Only use best-standards-support built into browsers config.action_dispatch.best_standards_support = :builtin # Raise exception on mass assignment protection for Active Record models config.active_record.mass_assignment_sanitizer = :strict # Log the query plan for queries taking more than this (works # with SQLite, MySQL, and PostgreSQL) config.active_record.auto_explain_threshold_in_seconds = 0.5 # Do not compress assets config.assets.compress = false # Expands the lines which load the assets config.assets.debug = true config.action_mailer.default_url_options = { :host => 'localhost:3000' } config.log_level = :warn end

• How do I reference an unsigned assembly from a VSTO Word Doc project?

  - by Gishu

  I created a new project in VS2008. Project type Visual C# > Office > 2007 > Word 2007 Document Added some code.. got Word to do a few jumps through some custom hoops.. all fine. Now I need to reference another assembly (CopyLocal as false) which is not signed. So I add the project reference. Now the project will not build complaining error MSB3188: Assembly 'X.dll' must be strong signed in order to be marked as a prerequisite. The error code page is concise (now accustomed to this) Been googling and reading posts ever since.. No Luck. How do I get around this ? Or is the hidden commandment that all references (for VSTO?) must be strong named / signed. I cannot sign 'X.dll' and be done with it because it is a binary that I don't control also it depends on another bunch of unsigned dlls.. can't set off a chain sign reaction. Update: Solved the build issue by turning CopyLocal=True. But this meant dumping the referenced X.DLL and all its dependencies into the bin\debug folder... Ughh! Tried creating a subfolder called bin\debug\refExecs and referencing X.dll CopyLocal=false from there. The error message was back.

• Sending jQuery.ajax data simultaneous to a form submit

  - by dscher

  I have a bit of a conundrum. I have a form which has numerous fields. There is one field for links where you enter a link, click an add button, and the link(using jQuery) gets added to a link_array. I want this array to be sent via the jQuery.ajax method when the form is submitted. If I send the link_array using $.ajax like this: $.ajax({ type: "POST", url: "add_stock", dataType: "json", data: { "links": link_array } }); when the add link button is selected the data goes no problem to the correct place and gets put in the db correctly. If I bind the above function to the submit form button using $(#stock_form).submit(..... then the rest of the form data is sent but not the link_array. I can obviously pass the link array back into a hidden field in HTML but then I'd have to unpack the array into comma separate values and break the comma-separated string apart in PHP. It just seems 100X easier to unpack the Javascript array in PHP without an other fuss. So, how is it that you can send an array from javascript using $.ajax concurrent to the rest of the $_POST data in HTML? Please note that I'm using Kohana 3.0 framework but really that shouldn't make a difference, what I want to do is add this js array to the $_POST array that is already going. Thanks!

• How to avoid game rendering component circular references?

  - by CodexArcanum

  I'm working on a simple game design, and I wanted to break up my game objects into more reusable components. But I'm getting stuck on how exactly to implement the design I have in mind. Here's an example: I have a Logger object, whose job is simply to store a list of messages and render them to screen. You know, logging. Originally the Logger just held the list, and the game loop rendered it's contents. Then I moved the rendering logic into the Logger.Draw() method, and now I want to move it further into a LoggerRenderer object. In effect, I want to have the game loop call RenderAll, which will then call Logger.Render, which will in turn call the LoggerRenderer.Render and finally output the text. So the Logger needs to contain a Renderer object, but the Renderer needs access to the Logger's state (the message queue) in order to render. How do I resolve that? Should I be passing in the message queue and other state information explicitly to the Render method? Or should the game loop be calling the Renderer directly and it links back to the logger, but the RenderAll method never actually sees the logger object itself? This feels kind of like Command pattern, but I'm botching it up terribly.

• Android animation's first frame is applied too early on ImageView

  - by Robert

  I have the following View setup in one of my Activities: <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/photoLayout" android:layout_width="fill_parent" android:layout_height="fill_parent"> <ImageView android:id="@+id/photoImageView" android:src="@drawable/backyardPhoto" android:layout_width="fill_parent" android:layout_height="fill_parent" android:gravity="center" android:scaleType="centerInside" android:padding="45dip" > </ImageView> </LinearLayout> Without an animation set, this displays just fine. However I want to display a very simple animation. So in my Activity's onStart override, I have the following: @Override public void onStart() { super.onStart(); mPhotoImageView = (ImageView) findViewById(R.id.photoImageView); float offset = -25; int top = mPhotoImageView.getTop(); TranslateAnimation anim1 = new TranslateAnimation( Animation.ABSOLUTE, 0, Animation.ABSOLUTE, 0, Animation.ABSOLUTE, top, Animation.ABSOLUTE, offset); anim1.setInterpolator(new AnticipateInterpolator()); anim1.setDuration(1500); anim1.setStartOffset(5000); TranslateAnimation anim2 = new TranslateAnimation( Animation.ABSOLUTE, 0, Animation.ABSOLUTE, 0, Animation.ABSOLUTE, offset, Animation.ABSOLUTE, top); anim2.setInterpolator(new BounceInterpolator()); anim2.setDuration(3500); anim2.setStartOffset(6500); mBouncingAnimation = new AnimationSet(false); mBouncingAnimation.addAnimation(anim1); mBouncingAnimation.addAnimation(anim2); mPhotoImageView.setAnimation(mBouncingAnimation); } The problem is that when the Activity displays for the first time, the initial position of the photo is not in the center of the screen with padding around. It seems like the first frame of the animation is loaded already. Only after the animation is completed, does the photoImageView "snap" back to the intended location. I've looked and looked and could not find how to avoid this problem. I want the photoImageView to start in the center of the screen, and then the animation to happen, and return it to the center of the screen. The animation should happen by itself without interaction from the user.

• SmartGwt DateItem useTextField=true - how to make text entry field UNeditable

  - by Paul

  Since I can't figure out how to solve my problem presented here I'm thinking for the moment at a temporary solution. I have a smartgwt DateItem widget: DateItem date = new DateItem("Adate"); date.setWidth(120); date.setWrapTitle(false); date.setAttribute("useTextField", true); date.setAttribute("inputFormat", "yyyy/MM/dd"); date.setAttribute("displayFormat", "toJapanShortDate"); Because the attribute useTextField is set to true we can see the text entry field. How can I make this text entry field to be uneditable. Actually I want to have only the possibility to choose the date from calendar and not to change it manually. Resolved - the issue exposed above - thanks to @RAS user. TextItem textItem = new TextItem(); textItem.setAttribute("readOnly", true); date.setAttribute("textFieldProperties", textItem); Related link But I have now another issue: The date chooser won't show the date on the text field but Today's date. For example, enter 30/05/2009 on the text field, go to another field, then come back on click on the date chooser and the selected day will be Today's date instead on June 30th, 2009. Which is the reason for this? Can this be solved? Also let's say I let to the user to opportunity to manually modify the date - can I put some validators on it? Thank you.

• Duck type testing with C# 4 for dynamic objects.

  - by Tracker1

  I'm wanting to have a simple duck typing example in C# using dynamic objects. It would seem to me, that a dynamic object should have HasValue/HasProperty/HasMethod methods with a single string parameter for the name of the value, property, or method you are looking for before trying to run against it. I'm trying to avoid try/catch blocks, and deeper reflection if possible. It just seems to be a common practice for duck typing in dynamic languages (JS, Ruby, Python etc.) that is to test for a property/method before trying to use it, then falling back to a default, or throwing a controlled exception. The example below is basically what I want to accomplish. If the methods described above don't exist, does anyone have premade extension methods for dynamic that will do this? Example: In JavaScript I can test for a method on an object fairly easily. //JavaScript function quack(duck) { if (duck && typeof duck.quack === "function") { return duck.quack(); } return null; //nothing to return, not a duck } How would I do the same in C#? //C# 4 dynamic Quack(dynamic duck) { //how do I test that the duck is not null, //and has a quack method? //if it doesn't quack, return null }

• Is there any way to combine transparency and "ajax usability" with HTML templates

  - by Sam

  I'm using HTML_Template_Flexy in PHP but the question should apply to any language or template library. I am outputting a list of relatively complex objects. In the beginning I just iterated over a list of the objects and called a toHtml method on them. When I was about to have my layout designer look over the template I noticed that it was too opaque and that he would have ended up looking through and/or editing many additional php source files to see what really gets generated by the toHtml method. So I extracted most of the HTML strings in the php classes up to the template which made for one clear file where you can see the whole page structure at once. However this causes problems when you want to add an object to the list using javascript. Then I have to keep the old toHtml method and maintain both the main template and the html strings at the same time, so I can output just the HTML for a new object that should be added to the page. So I'm back to the idea of using smaller templates for the objects that make up the page, but I was wondering if there was some easy way of having my cake and eating it too by having one template that shows the whole page but also the mini-templates for smaller objects on the page. Edit: Yes, updating the page is not a problem at all. My concern is with having both maintainability and transparency of the template files. If I have one single template for the whole page, then I must maintain mini-templates of the objects that are shown on the page. If I just have the mini-templates and include them from the higher-level template it becomes more difficult to look at the top-level html and imagine what the end result will look like.

  Hi, I have a small front end to a webshop. All customers that go through my website and buy an item from the webshop I get back 5% of the amount. I need to find a way af tracking the customers i forward from my webshop to the other webshop. And then get the webshop to reply to me when the purchase has been made. In my webshop i have made a small page: collect.aspx that requests and saves the values passed in the querystring, something like this pseudo code: string orderid = Request["orderid"]; string amount = Request["amount"]; ..save to database On the webshop i forward customers to i get to insert a javascript on the last page in the purchase flow. I have tried a lot of things but it seems that the only thing that works is to fool the browser into thinking im referring a javascript, like this: <script type="text/javascript" src="http://domain.com/mypage.aspx?orderid=4&amount=45/> I saw how other trackers did their bit, and this seems to be the general way of doing it. With this script however, i get all the orders, i only want to log those that belong tome, those who entered through my website. Here is my big problem, how to do this? I added a cookie when the user opens my page, and i want to check for this cookie again when the purchase page make the callback. It weems that i cant get the cookie from the browser when it makes the "" call. This is really buggin me now. Could anyone please tell me how this is generally done, this tracking. And what am i missing in regards to this cookie thing? All ideas on how to do this is very welcome.

• PHP database simulation

  - by Emdiesse

  I have a PHP script that works by calling items from a database based upon the time they were placed in there and it deletes them if they are older than 5 minutes. Basically, I want to now simulate what would happen if this database was being updated regularly. So I was considering sticking in some code that loads an XML file then goes through and parses that into the database based upon the time data located within a node of the xml data... but the problem there is I want it to continually loop through an enter this data so it'll never actually run the other processes So I was thinking of having another PHP script do that that could do this independantly of the php script that is going to display this data... In theory: I am looking to have a button that I can press and it will then run some php code to load up an XML file from a directory on my web server and then iterate though the data sending the data, to a database, based upon the time within a node in the PHP script and when the script was first called So back to my page that displayed the data... if I continually hit refresh it will contain different results each time because data is being added by the other process and this php script removes the older data when it is refreshed Any information on this? Is there a way I can silently, and safely, run a php script without it being loaded into a browser... like a thread!?

• window.location.href not working in Safari when using onkeypress

  - by insanepaul

  I'm using an asp textbox and a search button. In Safari if I click the search button i get redirected to the search results page using javascript window.location.href. But strangely the same javascript will not redirect to the page if I press return in the textbox. Using the alert function I can see that window.location.href has the the correct url and the location bar at the top changes from the search page(default.aspx) to the search results url however when I click OK to the alert box the url at the top reverts back to the default.aspx page. It works on ie7/8/firefox/chrome but not safari. Here is my javascript,cs and aspx code: function submitSearchOnEnter(e) { var CodeForEnter = 13; var codeEnteredByUser; if (!e) var e = window.event; if (e.keyCode) codeEnteredByUser = e.keyCode; else if (e.which) codeEnteredByUser = e.which; if (codeEnteredByUser == CodeForEnter) RedirectToSearchPage(); } function RedirectToSearchPage() { var searchText = $get('<%=txtHeaderSearch.ClientID%>').value if (searchText.length) { window.location.href = "Search.aspx?searchString=" + searchText; } } protected void Page_Load(object sender, EventArgs e) { txtHeaderSearch.Attributes.Add("onkeypress", "submitSearchOnEnter(event)"); } <asp:Panel ID="pnlSearch" runat="server" DefaultButton="lnkSearch"> <asp:TextBox ID="txtHeaderSearch" runat="server" CssClass="searchBox"></asp:TextBox> <asp:LinkButton ID="lnkSearch" OnClientClick="RedirectToSearchPage(); return false;" CausesValidation="false" runat="server" CssClass="searchButton"> SEARCH </asp:LinkButton> </asp:Panel> I've tried return false; which doesn't allow me to enter any characters in the search box. I've spent ages online trying to find a solution. Maybe it has something to do with setTimeout or setTimeInterval but it didn't work unless i did it wrong.

• Problems saving a photo to a file

  - by Peter vdL

  Man, I am still not able to save a picture when I send an intent asking for a photo to be taken. Here's what I am doing: Make a URI representing the pathname android.content.Context c = getApplicationContext(); String fname = c.getFilesDir().getAbsolutePath()+"/parked.jpg"; java.io.File file = new java.io.File( fname ); Uri fileUri = Uri.fromFile(file); Create the Intent (don't forget the pkg name!) and start the activity private static int TAKE_PICTURE = 22; Intent intent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE ); intent.putExtra("com.droidstogo.boom1." + MediaStore.EXTRA_OUTPUT, fileUri); startActivityForResult( intent, TAKE_PICTURE ); The camera activity starts, and I can take a picture, and approve it. My onActivityResult() then gets called. But my file doesn't get written. The URI is: file:///data/data/com.droidstogo.boom1/files/parked.jpg I can create thumbnail OK (by not putting the extra into the Intent), and can write that file OK, and later read it back). Can anyone see what simple mistake I am making? Nothing obvious shows up in the logcat - the camera is clearly taking the picture. Thanks, Peter

• Installing applications OTA

  - by Ed Marty

  I have a system set up to download jad files on users' Blackberries, but it only works intermittently, and seemingly randomly. If the user clicks on the link within their BlackBerry browser, 95% of the time on the first try an error message will pop up saying there was an HTTP 500 error (which our server never returns). Viewing the details of this message within the blackberry browser, it says nothing but java.lang.nullpointerexception which, again, could not have come from our server (running apache/php). However, if the user clicks on the link a few more times, or navigates away and goes back to that page, it suddenly works. No change on the server, it just shows the application install screen. Unfortunately, this doesn't always work; sometimes the error 500 just keeps showing up. The link is rather long (containing an sha hash as a token as part of the URL), but I would think that a long URL would either always be broken or always work, not work intermittently. The link uses a php script to download the jad and cod files. Linking to the files directly rather than using the script seems to work more often (I haven't determined if that also ever has an error 500 or not), but I can't find any issues with the headers. The content type is set correctly and, like I said, if the headers were an issue, I'd think it would either always work or always break. Any clues?

• Microsoft OLE DB Provider for SQL Server error '80040e14' Could not find stored procedure

  - by BBlake

  I am migrating a classic ASP web app to new servers. The database back end is migrating from SQL Server 2000 to SQL Server 2008, and the app is moving from Win2000 x86 to Win2003R2 x64. I am getting the above error on every single stored procedure call within the application. I have verified: Yes, the SQL user is set up, using correct username and password Yes, the SQL user has execute permissions on the stored procedures in the database Yes, I have updated the TypeLib references to the new UUID Yes, I have logged into the database via SSMS with the SQL user id and it can see and execute the stored procedures just fine in SSMS, but not from the web app. Yes, the SQL user has the database set as its default database. The most frustrating thing is it works fine on the DEV server, but not on the production server. I have gone through every IIS setting 5 or 6 times and the web app is set up precisely the same in both environments. The only difference is the database server name in the connection string (DEV vs prod) EDIT: I have also tried pointing the prod web box at the dev database server and get the same error so I'm fairly sure the issue isn't on the database side.

• What version control system is best designed to *prevent* concurrent editing?

  - by Fred Hamilton

  We've been using CVS (with TortoiseCVS interface) for years for both source control and wide-ranging document control (including binaries such as Word, Excel, Framemaker, test data, simulation results, etc.). Unlike typical version control systems, 99% of the time we want to prevent concurrent editing - when a user starts editing a file, the pre-edit version of the file becomes read only to everyone else. Many of the people who will be using this are not programmers or even that computer savvy, so we're also looking for a system that let's people simply add documents to the repository, check out and edit a document (unless someone else is currently editing it), and check it back in with a minimum of fuss. We've gotten this to work reasonably well with CVS + TortoiseCVS, but we're now considering Subversion and Mercurial (and open to others if they're a better fit) for their better version tracking, so I was wondering which one supported locking files most transparently. For example, we'd like exclusive locking enabled as the default, and we want to make it as difficult as possible for someone to accidentally start editing a file that someone else has checked out. For example when someone checks out a file for editing, it checks with the master database first even if they have not recently updated their sandbox. Maybe it even won't let a user check out a document if it's off the network and can't check in with the mothership.

• What's a good way to remove all of the subviews of a UIScrollView?

  - by Moshe

  I have a scroll view and I need to reload the contents often while my app is running. Right now, I'm using the following line of code to remove the subviews before adding them back again: [scrollView.subviews makeObjectsPerformSelector:@selector(removeFromSuperview)]; Should I be using the following instead? scrollView.subviews = nil; For some reason, the (first) above line of code seems to crash the app every 16 times it is run. Am I leaking memory somewhere? The following method takes an array of views, the scroller (which is a constant) and the direction. Edit: - (void)loadViews:(NSArray *)views IntoScroller:(UIScrollView *)scroller withDirection:(NSString *)direction{ //Set up the scrollView [scrollView.subviews makeObjectsPerformSelector:@selector(removeFromSuperview)]; if([direction isEqualToString:@"horizontal"]){ scrollView.frame = CGRectMake(0, 0, 1024, 768); scrollView.contentSize = CGSizeMake(scrollView.frame.size.width * [[NSNumber numberWithUnsignedInt:[views count]] floatValue], scrollView.frame.size.height); }else if([direction isEqualToString:@"vertical"]){ scrollView.frame = CGRectMake(0, 0, 1024, 768); scrollView.contentSize = CGSizeMake(scrollView.frame.size.width, scrollView.frame.size.height * [[NSNumber numberWithUnsignedInt:[views count]] floatValue]); } for (int i=0; i<[[NSNumber numberWithUnsignedInt:[views count]] intValue]; i++) { [[[views objectAtIndex:[[NSNumber numberWithInt:i] unsignedIntValue]] view] setFrame:scrollView.frame]; if([direction isEqualToString:@"horizontal"]){ [[[views objectAtIndex:[[NSNumber numberWithInt:i] unsignedIntValue]] view] setFrame:CGRectMake(i * [[views objectAtIndex:[[NSNumber numberWithInt:i] unsignedIntValue]] view].frame.size.width, 0, scrollView.frame.size.width, scrollView.frame.size.height)];//CGRectMake(i * announcementView.view.frame.size.width, -scrollView.frame.origin.x, scrollView.frame.size.width, scrollView.frame.size.height)]; }else if([direction isEqualToString:@"vertical"]){ [[[views objectAtIndex:[[NSNumber numberWithInt:i] unsignedIntValue]] view] setFrame:CGRectMake(0, i * [[views objectAtIndex:[[NSNumber numberWithInt:i] unsignedIntValue]] view].frame.size.height, scrollView.frame.size.width, scrollView.frame.size.height)]; } [scrollView addSubview:[[views objectAtIndex:[[NSNumber numberWithInt:i] unsignedIntValue]] view]]; } }

• PHP: Recursive array function

  - by Industrial

  Hi everybody, I want to create a function that returns the full path from a set node, back to the root value. I tried to make a recursive function, but ran out of luck totally. What would be an appropriate way to do this? I assume that a recursive function is the only way? Here's the array: Array ( [0] => Array ( [id] => 1 [name] => Root category [_parent] => ) [1] => Array ( [id] => 2 [name] => Category 2 [_parent] => 1 ) [2] => Array ( [id] => 3 [name] => Category 3 [_parent] => 1 ) [3] => Array ( [id] => 4 [name] => Category 4 [_parent] => 3 ) ) The result I want my function to output when getting full path of node id#4: Array ( [0] => Array ( [id] => 1 [name] => Root category [_parent] => ) [1] => Array ( [id] => 3 [name] => Category 3 [_parent] => 1 ) [2] => Array ( [id] => 4 [name] => Category 4 [_parent] => 3 ) ) The notoriously bad example of my recursive skills: function recursive ($id, $array) { $innerarray = array(); foreach ($array as $k => $v) { if ($v['id'] === $id) { if ($v['_parent'] !== '') { $innerarray[] = $v; recursive($v['id'], $array); } } } return $innerarray; } Thanks!
