  • guide for creating addins for Visual Studio 2010?

    - by JMarsch
    Hello: 2 questions actuall: Is there a good comprensive guide out there for creating add-ins for Visual Studio? Here's a weird specific problem -- I'm trying to get my add-in to load. The code that the wizard stubs into the OnConnect method will add it to the toolbar, but only if it passes this "if" statement: if (connectMode == ext_ConnectMode.ext_cm_UISetup) The problem is that connectMode never seems to equal ext_cm_UISetup. It always seems to equal ext_cm_AfterStartup, and My AddIn never appears on the toolbar. I could cheat and short-circuit the if, but since Visual Studio put that code there, I bet it's right, and I have something else wrong. According to the docs, the value should only ever be ext_cm_UISetup once -- the first time VS encounters the addin. So I probably need to somehow make VS forget about the add-in, but I can't find anywhere to do that. And by the way, isn't that exceptionally delicate? The reason I'm in this pickle is because I happened to get an exception on the first try, so now I can never try again?? Can't be right.

  • Why doesn't ${locale} resolve in my <compc> Ant task?

    - by user165462
    I've seen a number of examples, e.g. here, where people are including locale resource bundles by referencing the locale attribute in the element. For some reason this doesn't work for me. Here's what I have for the task: <compc output="${deploy.dir}/myfrmwrk.swc" locale="en_US"> <source-path path-element="${basedir}/src/main/flex"/> <include-sources dir="${basedir}/src/main/flex" includes="*" /> <include-libraries file="${basedir}/libs"/> <compiler.external-library-path dir="${FLEX_HOME}/frameworks/libs/player/9" append="true"> <include name="playerglobal.swc"/> </compiler.external-library-path> <compiler.library-path dir="${FLEX_HOME}/frameworks" append="true"> <include name="libs"/> <include name="locale/${locale}"/> </compiler.library-path> <load-config filename="${basedir}/fb3config.xml" /> </compc> This fails with a bunch of errors of the form: [compc] Error: could not find source for resource bundle ... I can make it build with this one change: <include name="locale/en_US"/> The configuration file generated by Flex Builder 3 actually renders this as "locale/{locale}" (notice the $ is missing). I've tried that as well with the same (failing) results. For now, I'm doing OK directly injecting en_US as we won't be doing localization bundles for quite some time, but I will eventually need to get this working. Also, it bugs me that I can't make it work the way that it SHOULD work!

  • Run Jmol applet using apache server

    - by user1144004
    I am a newbie in using apache and jmol. I am trying to run a jmol applet in python using apache server. Because of strict folder arrangement restrictions in jmol (html and model files should be present inside jmol folder), I had to move the default htdocs and cgi-bin folder inside jmol folder by editing the "httd.conf" file. Now the new location of htdocs folder is "Apache2.2/jmol/htdocs" and of cgi-bin folder is "Apache2.2/jmol/cgi-bin". Now I've put my "start.html" file in the htdocs folder which has the jmol applet tag. It takes "CA150.XYZ" file which is also placed in the same folder. On running this "start.html" file through apache server, nothing happens. It even doesn't give any error, it just shows a blank page. But if I try to run "start.html" without apache server, jmol applet do get executed and runs successfully. What am I doing wrong? Any idea? Here is my "start.html" file <head> <title>Simple example</title> <script src="../Jmol.js" type="text/javascript"></script> </head> <body> <form> <script type="text/javascript"> jmolInitialize("../"); jmolApplet(200,"load CA150.XYZ"); </script> </form> </body>

  • gcc compilations (sometimes) result in cpu underload

    - by confusedCoder
    I have a larger C++ program which starts out by reading thousands of small text files into memory and storing data in stl containers. This takes about a minute. Periodically, a compilation will exhibit behavior where that initial part of the program will run at about 22-23% CPU load. Once that step is over, it goes back to ~100% CPU. It is more likely to happen with O2 flag turned on but not consistently. It happens even less often with the -p flag which makes it almost impossible to profile. I did capture it once but the gprof output wasn't helpful - everything runs with the same relative speed just at low cpu usage. I am quite certain that this has nothing to do with multiple cores. I do have a quad-core cpu, and most of the code is multi-threaded, but I tested this issue running a single thread. Also, when I run the problematic step in multiple threads, each thread only runs at ~20% CPU. I apologize ahead of time for the vagueness of the question but I have run out of ideas as to how to troubleshoot it further, so any hints might be helpful. UPDATE: Just to make sure it's clear, the problematic part of the code does sometimes (~30-40% of the compilations) run at 100% CPU, so it's hard to buy the (otherwise reasonable) argument that I/O is the bottleneck

  • Getting hover text with selenium in java

    - by BinaryEmpire
    I am trying to figure out how to get the product availability text from a page like http://www.walmart.com/browse/TV-Video/TVs/_/N-96v3? (once a store has been selected) I selected 76574 as my zipcode and went to the "In My Store" tab The code I have now is WebElement hoverElement = driver.findElement(By.xpath(".//*[@id='Body_15992428']/span")); WebElement hidden = driver.findElement(By.xpath(".//*[@id='slapInfo_NoVariant_15992428']/div")); Actions builder = new Actions(driver); builder.clickAndHold(hoverElement).build().perform(); System.out.println(hidden.getText()); **Edit: I tried profile.setEnableNativeEvents(false); and the text is now displayed in the automated browser window. I still cannot get to the text I want though. It does not throw an exception, only displays nothing because the driver thinks its still hidden. Any one know how to fix this? I keep getting Exception in thread "main" org.openqa.selenium.InvalidElementStateException: Cannot perform native interaction: Could not load native events component. Even after I do profile.setEnableNativeEvents(true); Are there any other ways I can get the hidden text, or what am I doing wrong here? Additionally while I was inspecting the code with firebug, I saw that there is this code <script type="text/javascript"> WALMART.$(document).ready(function(){ WALMART.$('#Body_15992428').hover(function(){ WALMART.$('#SeeStoreAvailBubble').wmBubble('update',WALMART.$('#bubbleMsgUpdate_15992428').html()); }); }); </script> I dont really know how to do things directly with javascript but is there is any way of getting the message text directly from that with a javascript executor?

  • 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.

  • Encode_JSON Errors in Lasso 8.6.2 After Period of Time

    - by ATP_JD
    We are in the process of converting apps from Lasso 8 to Lasso 9, and as an intermediate step, have upgraded from 8.5.5 to 8.6.2 (which runs alongside 9 on our new box, in different virtual hosts). I am finding that with 8.6.2 we are getting a slew of errors on pages that call encode_json. The weird thing with these errors is that they don't start happening until some period of time after the site starts. Then, some hours later, all encode_json calls begin to fail with error messages like this: An error occurred while processing your request. Error Information Error Message: No tag, type or constant was defined under the name "?????????????????" with arguments: array: (pair: (-find)=([\x{0020}-\x{21}\x{23}-\x{5b}\x{5d}-\x{10fff}])), (r) at: onCompare with params: 'r' at: JSON with params: 'reload', -Options=array: (-Internal) at: JSON with params: @map: (reload)=(false), (tcstring)=(LZU), (timestring)=(10:42 AM&nbsp;&nbsp;&nbsp;1442Z) at: [...].lasso with params: 'pageloadtime'='1383038310' on line: 31 at position: 1 Error Code: -9948 (Yes, those Chinese(?) characters are in the error message.) I have removed the 8.5.5 encode_json tag from LassoStartup, so we are using the correct built-in method. The encode_json method fails for any and all parameters I throw at it from simple strings to arrays of maps. Upon restarting the site, encode_json resumes working for an hour or two, seemingly depending on load. On 8.5.5, we don't have this problem. Does anyone have experience with this issue? Any advice regarding trying the 8.5.5 tag swap encode_json to see if I can override the built-in method? Maybe it will work better? Thanks in advance for your time and assistance. -Justin

  • SQL Query to separate data into two fields

    - by Phillip
    I have data in one column that I want to separate into two columns. The data is separated by a comma if present. This field can have no data, only one set of data or two sets of data saperated by the comma. Currently I pull the data and save as a comma delimited file then use an FoxPro to load the data into a table then process the data as needed then I re-insert the data back into a different SQL table for my use. I would like to drop the FoxPro portion and have the SQL query saperate the data for me. Below is a sample of what the data looks like. Store Amount Discount 1 5.95 1 5.95 PO^-479^2 1 5.95 PO^-479^2 2 5.95 2 5.95 PO^-479^2 2 5.95 +CA8A09^-240^4,CORDRC^-239^7 3 5.95 3 5.95 +CA8A09^-240^4,CORDRC^-239^7 3 5.95 +CA8A09^-240^4,CORDRC^-239^7 In the data above I want to sum the data in the amount field to get a gross amount. Then pull out the specific discount amount which is located between the carat characters and sum it to get the total discount amount. Then add the two together and get the total net amount. The query I want to write will separate the discount field as needed, see store 2 line 3 for two discounts being applied, then pull out the value between carat characters.

  • Recover lost code from compiled apk

    - by AlexRamallo
    I have an issue here..and its making me really nervous. I was working on this game, and it was going great, so I took a copy of it on my laptop to work do some work while away from my computer. long story short, hard-drive failure + poor back ups led to me losing a very important class. Is there a way to decompile the apk to retrieve the bit of code that was lost? It isn't overly complicated or sophisticated, its just that its impossible to re-write it without reading every. single. line. of. code. in the entire application since it initializes a LOT of classes and loads a bunch of stuff in a specific way. With a quick google search I was able to find apktool, which decompiles it into a bunch of .smali files, which I don't think were designed for human reading. All I need to recover is one very big method in the class. I found the smali file that contains it and I think I found the line where it starts. something like .method public declared-synchronized load(Lcom/X/X/game/X;)I Anyone help would be appreciated since I would have to scrap the entire game without this method.

  • Refresh Div with Jquery at fixed time

    - by Ben C
    I've got a php script that tells me when the next bus is due, and at the moment I'm refreshing this into a div, using jquery, every minute or so. Now, because I know the time at which the data will change (after the bus has come), I want it to refresh the div at this time (or just after, doesn't really matter). I should point out that I'm fairly new to js, but this is what I've got so far: var nextbustime = $('#bus').contents(); var nextbustime = new Date(nextbustime); var now = new Date(); var t = nextbustime.getTime() - now.getTime(); var refreshId = setTimeout(function() { $('#bus').fadeOut("slow").load('modules/bus.php?randval='+ Math.random()).fadeIn("slow"); }, t); The div is loaded originally with a php include. Naturally, what I've done doesn't work at all. Do I need some loops going on? Do I need to refresh the time calculator? Please please help! Thanks in advance...

  • sendto is returning ENOBUF

    - by user338159
    Hi, I am currently running an old system on Tru64 which involves lots of UDP sockets using the sendto() function. The sockets are used in our code to send messages to/from various processes and then eventually on to a thick client app that is connected remotely. Occasionally the socket to the thick client gets stuck, this can cause some of these messages to get built up. My question is how can I determine the current buffer size, and how do I determine the maximum message buffer. The code below gives a snippet of how I set up the port and use the sendto function. /* need to adjust the maximum size we can send on this / / as it needs to be able to cope with the biggest / / messages we send / lenlen = sizeof(len) ; / allow double for when the system is under load */ len = 2 * C_MAX_MESSAGE_DATA_SIZE ; lpos_setsockopt(FATAL, msg_socket,SOL_SOCKET, SO_SNDBUF, &len, lenlen, &error_no) ; result = sendto( msg_socket, (char *)message, (int)message_len, flags, dest_addr, addrlen); Note. We have ported this application to Linux and the problem does not seem to appear there. Any help would be greatly appreciated. Regards

  • mscomctl.ocx on my dev machine gives me problems since security patch of MS

    - by Bronzato
    I am busy on this problem since 2 days ago and hope someone can get me out of it. I have Excel 2010 (full install 944Mb) on my Windows 8 computer. It works well. But when I modify my workbook (containing a ListView version 6.0) I am not able to run it on my client's computer. I get the error: Could Not Load An Object. Not Available on This Machine. Even it works well on my dev machine. The reason is: Microsoft applied a Security Patch (near august 2012 I think) on mscomctl.ocx and my Excel 2010 installation files (downloaded not long ago) contains the new version of mscomctl.ocx. The clients using my Excel file don't apply the security patch at this moment. Se everytime I publish my Excel file to client's computers (from my dev environment), I reference the new mscomctl.ocx. That's the problem. I already try to get the old mscomctl.ocx from client's computer and copy & register it on my dev machine but then I got errors (Class not registered, ...) when I create a userform and drag a listview on it. So: mscomctl.ocx on client's machine is version 6.1.98.13 from 2008. mscomctl.ocx on my dev machine is version 6.1.98.34 from 2012. My question: Does someone have an idea how to proceed to have a usable version of mscomctl.ocx on my dev machine? Thank you very much.

  • reset TextView scroll to top

    - by JayAvon
    Okay well I apologize for how sloppy this code is, but I still cant figure out how to post a code tag on here correctly. So I am making an Android application (Java) and i have a scrolling text field. If the user scrolls a long row down and stays at the end when they click the next row and if it is short, it will be scrolled down on that element too even though it may be a 1 line(and non scrollable) row. I was wondering if there is any way I can call something to right after txtLvlInfo.setText to reset the x-scroll value to 0 or something so it is always reset to the top of the content, long or short. Thanks for any help with this and please let me know if I need to clarify more. TextView txtLvlInfo = (TextView) findViewById(R.id.txtLevelInfo); txtLvlInfo.setMovementMethod(new ScrollingMovementMethod()); switch (v.getId()){ case R.id.row1: txtLvlInfo.setText("1: My text view is only two lines max and so I set it to scroll, if the user clicks row2 to load that text while having me scrolled down they have to click and pull to drag back down to the top of text view 2 row."); break; case R.id.row2: txtLvlInfo.setText("I only fill line 1 of the two."); break; android:textColor="#052027" android:text="" android:id="@+id/txtLevelInfo" android:scrollbars="vertical" android:layout_alignParentLeft="true" android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_toRightOf="@+id/minimizeBtn" android:layout_marginRight="38dip"

  • Help me refactor my World Cup Challenge Script

    - by kylemac
    I am setting up a World Cup Challenge between some friends, and decided to practice my Ruby and write a small script to automate the process. The Problem: 32 World Cup qualifiers split into 4 tiers by their Fifa ranking 8 entries Each entry is assigned 1 random team per tier Winner takes all :-) I wrote something that suffices yet is admittedly brute force. But, in my attempt to improve my Ruby, I acknowlege that this code isn't the most elegant solution around - So I turn to you, the experts, to show me the way. It may be more clear to check out this gist - https://gist.github.com/91e1f1c392bed8074531 My Current (poor) solution: require 'yaml' @teams = YAML::load(File.open('teams.yaml')) @players = %w[Player1 Player2 Player3 Player4 Player5 Player6 Player7 Player8] results = Hash.new players = @players.sort_by{rand} players.each_with_index do |p, i| results[p] = Array[@teams['teir_one'][i]] end second = @players.sort_by{rand} second.each_with_index do |p, i| results[p] << @teams['teir_two'][i] end third = @players.sort_by{rand} third.each_with_index do |p, i| results[p] << @teams['teir_three'][i] end fourth = @players.sort_by{rand} fourth.each_with_index do |p, i| results[p] << @teams['teir_four'][i] end p results I am sure there is a better way to iterate through the tiers, and duplicating the @players object ( dup() or clone() maybe?) So from one Cup Fan to another, help me out.

  • initWithContentsOfURL seems to have issues with "long" URLs

    - by samsam
    Hi there I'm facing a rather strange Issue when trying to load data from an XML-Webservice. The webservice allows me to pass separated identifiers within the URL-Request. It is therefore possible for the URL to become rather long (240 characters). If I open said URL in firefox the response arrives as planned, if I execute the following code xmlData remains empty. NSString *baseUrl = [[NSString alloc] initWithString:[[[[kSearchDateTimeRequestTV stringByReplacingOccurrencesOfString:@"{LANG}" withString:appLanguageCode] stringByReplacingOccurrencesOfString:@"{IDENTIFIERS}" withString:myIdentifiers] stringByReplacingOccurrencesOfString:@"{STARTTICKS}" withString:[NSString stringWithFormat:@"%@", [[startTime getTicks] descriptionWithLocale:nil]]] stringByReplacingOccurrencesOfString:@"{ENDTICKS}" withString:[NSString stringWithFormat:@"%@", [[endTime getTicks] descriptionWithLocale:nil]]]]; NSLog(baseUrl); //looks good, if openend in browser, returnvalue is ok urlRequest = [NSURL URLWithString:baseUrl]; NSString *xmlData = [NSString stringWithContentsOfURL:urlRequest encoding:NSUTF8StringEncoding error:&err]; //err is nil, therefore i guess everything must be ok... :( NSLog(xmlData); //nothing... is there any sort of URL-Length restriction, does the same problem happened to anyone of you as well? whats a good workaround? thanks for your help sam

    I'm trying to create a site that requires login. Its entirely designed in silverlight. So my first page, home.xaml loads in mysite.aspx and it basically has a login page. AFter login, the user is redirected to another page user.aspx. in that page, i've embedded another silverlight control called nav.xaml. so now when user.aspx loads it is supposed to load a silverlight control. i've programmed app.xaml.vb such that it loads nav.xaml in the rootlayout when the page requesting is user.aspx. but for some reason its not working. my app.xaml.vb code: Private Sub Application_Startup(ByVal o As Object, ByVal e As StartupEventArgs) Handles Me.Startup If e.InitParams.ContainsKey("ReqPage") Then If e.InitParams("ReqPage") = "userpage" Then Me.RootVisual = New Nav() End If Else Me.RootVisual = New Home() End If End Sub in IE, half of the nav.xaml is rendered. but in firefox nothing is rendered. so wats going on exactly? pls help!

  • C#: at design time, how can I reliably determine the type of a variable that is declared using var?

    - by Cheeso
    I'm working on a completion (intellisense) facility for C# in emacs. The idea is, if a user types a fragment, then asks for completion via a particular keystroke combination, the completion facility will use .NET reflection to determine the possible completions. Doing this requires that the type of the thing being completed, be known. If it's a string, it has a set of known methods; if it's an Int32, it has a separate set of methods, and so on. Using semantic, a code lexer/parser package available in emacs, I can locate the variable declarations, and their types. Given that, it's straightforward to use reflection to get the methods and properties on the type, and then present the list of options to the user. The problem arrives when the code uses var in the declaration. How can I reliably determine the actual type used, when the variable is declared with the var keyword? Just to be clear, I don't need to determine it at runtime. I want to determine it at "Design time". So far the best idea I have is: extract the declaration statement, eg var foo = "a string value"; concatenate a statement foo.GetType(); dynamically compile the resulting C# fragment it into a new assembly load the assembly into a new AppDomain, run the framgment and get the return type. unload and discard the assembly This sounds awfully heavyweight, for each completion request in the editor. Any better ideas out there?

  • Setting Image.Source doesn't update when loading from a resource.

    - by ChrisF
    I've got this definition in my XAML: <Image Name="AlbumArt" Source="/AlbumChooser2;component/Resources/help.png" /> The image is display OK on startup. In my code I'm looking for mp3's to play and I display the associated album art in this Image. Now if there's no associated image I want to display a "no image" image. So I've got one defined and I load it using: BitmapImage noImage = new BitmapImage( new Uri("/AlbumChooser2;component/Resources/no_image.png", UriKind.Relative)); I've got a helper class that finds the image if there is one (returning it as a BitmapImage), or returns null if there isn't one: if (findImage.Image != null) { this.AlbumArt.Source = findImage.Image; // This works } else { this.AlbumArt.Source = noImage; // This doesn't work } In the case where an image is found the source is updated and the album art gets displayed. In the case where an image isn't found I don't get anything displayed - just a blank. I don't think that it's the setting of AlbumArt.Source that's wrong, but the loading of the BitmapImage. If I use a different image it works, but if I recreate the image it doesn't work. What could be wrong with the image?

  • 3 questions about JSON-P format.

    - by Tristan
    Hi, I have to write a script which will be hosted on differents domains. This script has to get information from my server. So, stackoverflow's user told me that i have to use JSON-P format, which, after research, is what i'm going to do. (the data provided in JSON-P is for displaying some information hosted on my server on other website) How do I output JSON-P from my server ? Is it the same as the json_encode function from PHP How do i design the tree pattern for the output JSON-P (you know, like : ({"name" : "foo", "id" : "xxxxx", "blog" : "http://xxxxxx.com"}); can I steal this from my XML output ? (http://bit.ly/9kzBDP) Each time a visitor browse a website on which my widget is it'll make a request on my server, requesting the JSON-P data to display on the client side. It'll increase dramatically the CPU load (1 visitor on the website who will have the script = 1 SQL request on my server to output data), so is there any way to 'caching' the JSON-P information output to refresh it only one or twice a day and stores it into a 'file' (in which extension?). BUT on the other hand i would say that requesting the JSON-P data directly (without caching it) is a plus, because, websites which will integrates the script only want to display THEIR information and not the whole data. So, making a script with something like that: jQuery.getJSON("http://www.something.com/json-p/outpout?filter=5&callback=?", function(data) { ................); }); Where filter= the information the website wants to display What do you think ? Thank you very much ;)

    Hello, I'm writing an application that has a scrollable image (used to display a map). The map background consists of several tiles (premade from a big JPG file), that I draw on a Graphics object. I also use a cache (Hashtable), to prevent from having to create every image when I need it. I don't keep everything in memory, because that would be too much. The problem is that when I'm scrolling through the map, and I need an image that wasn't cached, it takes about 60-80 ms to create it. Depending on screen resolution, tile size and scroll direction, this can occur multiple times in one scroll operation (for different tiles). In my case, it often happens that this needs to be done 4 times, which introduces a delay of more than 300 ms, which is extremely noticeable. The easiest thing for me would be that there's some way to speed up the creation of Images, but I guess that's just wishful thinking... Besides that, I suppose the most obvious thing to do is to load the tiles predictively (e.g. when scrolling to the right, precache the tiles to the right), but then I'm faced with the rather difficult task of thinking up a halfway decent algorithm for this. My actual question then is: how can I best do this predictive loading? Maybe I could offload the creation of images to a separate thread? Other things to consider? Thanks in advance.

  • Using the standard OBJECT tag, how can I display a java applet with automatic prompts to install Java and with fallback content?

    - by CB
    This is the code i'm currently using: (note - %s is replaced on the server side) <!--[if !IE]>--> <object type="application/x-java-applet" width="300" height="300" > <!--<![endif]--> <!--[if IE]> <object classid="clsid:8AD9C840-044E-11D1-B3E9-00805F499D93" codebase="http://java.sun.com/update/1.6.0/jinstall-6u22-windows-i586.cab" type="application/x-java-applet" width="300" height="300" > <!--><!-- <![endif]--> <param name="codebase" value="/media/vnc/" > <param name="archive" value="TightVncViewer.jar" /> <param name="code" value="com.tightvnc.vncviewer.VncViewer" /> <param name="port" value="%s" /> <param name="Open New Window" value="yes" /> </object> When Java is installed, this works perfectly in both IE and Firefox. When Java is not installed, IE and Firefox both correctly prompt for an autodownload of Java 1.6 from the codebase line. (IE via the activex url given firefox via the Plugin Finder Service) Now, suppose I want fallback content to be shown if the plugin isn't installed, say a simple message like "Get Java". From reading the specs, i'd assume this should not change the plugin finding prompt - that is, rendering the fallback should be seen as a failure to render the object tag. Thus, I should still get the plugin finder service prompting me to install Java. Instead, simply adding a single character to the innerHTML of the object element causes Firefox to no longer prompt. Test this by visiting data:text/html,<object type='application/x-java-applet'>Java failed to load</object>. How can I keep firefox prompting to install Java while providing fallback content? URL to test Firefox's Java Plugin Finder Service: data:text/html,<object type='application/x-java-applet'/>

  • Is there a project setting that controls getting to Game Center's Sandbox?

    - by CBGraham
    This is different from the others; it's cool. I know that your Bundle Identifier needs to match your iTunes Connect's version. I know you need to make a new AppleID through your dev app and not through Game Center. Most people get this fixed when they force quit their app and game center and launch theirs first. I am not one of those people. If I take the GKTapper tutorial and use my game's Bundle Identifier as the only change, things are good. On launch, it asks me if I want to use an existing or make a new account. But more importantly, it says * Sandbox *. (Before I log in, mind you; this is not an account problem at all.) Once inside I can see my achievements. If I load my game, I has a sad. On launch I get the same dialog, but it does not say Sandbox. My game is two weeks away from being done after many long months. Moving everything in to a new project is possible, but a pain. So the question is: What magic setting does GKTapper or a new project have that my game that I started in June does not that lets you get to Game Center's Sandbox?

  • 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)
