• Getting Database Data to the client side.

  - by Toby Allen

  I'm sure this has been asked a million times, but what is the accepted approach to this? I have been writing php code for a while and up until recently I only copied+pasted javascript code, but now with help from YUI I've begun to understand javascript and want to use it more in an existing web app I have. I want to get various amounts of data from databases etc to the clientside javascript. I have access to this data in my php pages when loading. What is the correct way to get this data to my client side script. Generate clientside javascript in my php or smarty template files inserting the data where I need it? Use an Ajax call to retrieve the information I need from a php file - returning JSON data? Generate a JSON data construct of the data needed by the page and either return it via a script inclusion or dumping it to the generated page? Something really obvious I haven't thought of.

• how to load c# object side by side

  - by mamu

  We have serialized value of some objects persisted. Now we want to make substantial changes to some objects. So what i want to do is load older version of object using old assembly then deserialize and serialize again with newer version of the object. I can have convert method which can transform old object to new one. i have been converting object on fly on deserializer but in this case it's almost new object with same name.

• how close a connection from server side that created by ajax from client side

  - by saeid

  I have this sample php code: <?php function response($a) { @ob_end_clean(); header("Connection: close"); ob_start(); echo $a; $length = ob_get_length(); header("Content-Length: $length"); ob_end_flush(); flush(); } response("test1"); sleep(5); echo "test2"; ?> now I make a connection to server from client by ajax. now I want to server only send "test1" to me and then close the connection. but connection not closed and wait 5 seconds and send me "test1 test2" !! this is response headers from server to me : X-Powered-By: PHP/5.3.27 Connection: close Vary: Accept-Encoding,User-Agent Content-Encoding: gzip Cache-Control: private, no-cache, no-store, ------revalidate, no-transform Transfer-Encoding: chunked Content-Type: text/html in response headers I do not see Content-Length header. is problem for this ?? or if not what I must do now for solving problem ??

• Change object on client side or on server side

  - by Polina Feterman

  I'm not sure what is the best practice. I have some big and complex objects (NOT flat). In that object I have many related objects - for example Invoice is the main class and one of it's properties is invoiceSupervisor - a big class by it's own called User. User can also be not flat and have department property - also an object called Department. For example I want create new Invoice. First way: I can present to client several fields to fill in. Some of them will be combos that I will need to fill with available values. For example available invoiceSupervisors. Then all the chosen values I can send to server and on server I can create new Invoice and assign all chosen values to that new Invoice. Then I will need to assign new supervisor I will pull the chosen User by id that user picked up on server from combobox. I might do some verification on the User such as does the user applicable to be invoice supervisor. Then I will assign the User object to invoiceSupervisor. Then after filling all properties I will save the new invoice. Second way: In the beginning I can call to server to get a new Invoice. Then on client I can fill all chosen values , for example I can call to server to get new User object and then fill it's id from combobox and assign the User as invoiceSupervisor. After filling the Invoice object on client I can send it to server and then the server will save the new invoice. Before saving server can run some validations as well. So what is the best approach - to make the object on client and send it to server or to collect all values from client and to make a new object on server using those values ?

• Issue creating side-by-side slideshows with jQuery

  - by JShweky

  I'm trying to create a site with 2 slideshows. I've tweaked and re-tweaked the JS and Jquery numerous times. Sometimes one slideshow works perfectly and the other cycles between one picture, other times both work but are out of sync, or the fadeIn doesn't seem to be applied to the second slideshow, or in some variations one slideshow stays frozen on the initial image and just remains static. Anyway, I created a JS Fiddle (link at bottom) and apparently my code is at least free of typos. JS is below, the rest is on the JS Fiddle. Any help would be greatly appreciated. $(document).ready(function () { $(".slider #1").fadeIn(1000); $(".slider #1").delay(2000).fadeOut(1000); var sc = $(".slider img").size(); var count = 2; setInterval(function () { $(".slider #" + count).fadeIn(1000); $(".slider #" + count).delay(2000).fadeOut(1000); if (count === sc) { count = 1; } else { count++; } }, 3500); $(".sliderTwo #7").fadeIn(1000); $(".sliderTwo #7").delay(2000).fadeOut(1000); var sc2 = 12; var count2 = 7; setInterval(function () { $(".sliderTwo #" + count2).fadeIn(1000); $(".sliderTwo #" + count2).delay(2000).fadeOut(1000); if (count2 === sc2) { count2 = 7; } else { count2++; } }, 3500); }); http://jsfiddle.net/gg4PL/

• Are closures with side-effects considered "functional style"?

  - by Giorgio

  Many modern programming languages support some concept of closure, i.e. of a piece of code (a block or a function) that Can be treated as a value, and therefore stored in a variable, passed around to different parts of the code, be defined in one part of a program and invoked in a totally different part of the same program. Can capture variables from the context in which it is defined, and access them when it is later invoked (possibly in a totally different context). Here is an example of a closure written in Scala: def filterList(xs: List[Int], lowerBound: Int): List[Int] = xs.filter(x => x >= lowerBound) The function literal x => x >= lowerBound contains the free variable lowerBound, which is closed (bound) by the argument of the function filterList that has the same name. The closure is passed to the library method filter, which can invoke it repeatedly as a normal function. I have been reading a lot of questions and answers on this site and, as far as I understand, the term closure is often automatically associated with functional programming and functional programming style. The definition of function programming on wikipedia reads: In computer science, functional programming is a programming paradigm that treats computation as the evaluation of mathematical functions and avoids state and mutable data. It emphasizes the application of functions, in contrast to the imperative programming style, which emphasizes changes in state. and further on [...] in functional code, the output value of a function depends only on the arguments that are input to the function [...]. Eliminating side effects can make it much easier to understand and predict the behavior of a program, which is one of the key motivations for the development of functional programming. On the other hand, many closure constructs provided by programming languages allow a closure to capture non-local variables and change them when the closure is invoked, thus producing a side effect on the environment in which they were defined. In this case, closures implement the first idea of functional programming (functions are first-class entities that can be moved around like other values) but neglect the second idea (avoiding side-effects). Is this use of closures with side effects considered functional style or are closures considered a more general construct that can be used both for a functional and a non-functional programming style? Is there any literature on this topic? IMPORTANT NOTE I am not questioning the usefulness of side-effects or of having closures with side effects. Also, I am not interested in a discussion about the advantages / disadvantages of closures with or without side effects. I am only interested to know if using such closures is still considered functional style by the proponent of functional programming or if, on the contrary, their use is discouraged when using a functional style.

• How to place rooms proceduraly (rule based) on in a game word

  - by gardian06

  I am trying to design the algorithm for my level generation which is a rule driven system. I have created all the rules for the system. I have taken care to insure that all rooms make sense in a grid type setup. for example: these rooms could make this configuration The logic flow code that I have so far Door{ Vector3 position; POD orient; // 5 possible values (up is not an option) bool Open; } Room{ String roomRule; Vector3 roomPos; Vector3 dimensions; POD roomOrient; // 4 possible values List doors<Door>; } LevelManager{ float scale = 18f; List usedRooms<Room>; List openDoors<Door> bool Grid[][][]; Room CreateRoom(String rule, Vector3 position, POD Orient){ place recieved values based on rule fill in other data } Vector3 getDimenstions(String rule){ return dimensions of the room } RotateRoom(POD rotateAmount){ rotate all items in the room } MoveRoom(Room toBeMoved, POD orientataion, float distance){ move the position of the room based on inputs } GenerateMap(Vector3 size, Vector3 start, Vector3 end){ Grid = array[size.y][size.x][size.z]; Room floatingRoom; floatingRoom = Room.CreateRoom(S01, start, rand(4)); usedRooms.Add(floatingRoom); for each Door in floatingRoom.doors{ openDoors.Add(door); } // fill used grid spaces floatingRoom = Room.CreateRoom(S02, end, rand(4); usedRooms.Add(floatingRoom); for each Door in floatingRoom.doors{ openDoors.Add(door); } Vector3 nRoomLocation; Door workingDoor; string workingRoom; // fill used grid spaces // pick random door on the openDoors list workingDoor = /*randomDoor*/ // get a random rule nRoomLocation = workingDoor.position; // then I'm lost } } I know that I have to make sure for convergence (namely the end is reachable), and to do this until there are no more doors on the openDoors list. right now I am simply trying to get this to work in 2D (there are rules that introduce 3D), but I am working on a presumption that a rigorous algorithm can be trivially extended to 3D. EDIT: my thought pattern so far is to take an existing open door and then pick a random room (restrictions can be put in later) place that room's center at the doors location move the room in the direction of the doors orientation half the rooms dimension w/respect to that axis then test against the 3D array to see if all the grid points are open, or have been used, or if there is even space to put the room (caseEdge) if caseEdge (which can also occur in between rooms) then put the door on a toBeClosed list, and remove it from the open list (placing a wall or something there). then to do some kind of test that both the start, and the goal are connected, and reachable from each other (each room has nodes for AI, but I don't want to "have" to pull those out to accomplish this). but this logic has the problem for say the U, or L shaped rooms in my example, and then I also have a problem conceptually if the room needs to be rotated.

• ASP.NET MVC2: Client-side validation not working with Start.js

  - by Shaggy13spe

  Ok, this is strange. I would hope it's something I'm doing wrong and not that MS has two technologies that simply don't work together. (UPDATE: See bottom of post for Script tag order in HEAD section) I'm trying to use the dataView template and client-side validation. If I include a reference to: <script src="http://ajax.microsoft.com/ajax/beta/0911/Start.js" type="text/javascript"></script> by itself, the dataview template works fine. but if I put in the following references: <script src="http://ajax.microsoft.com/ajax/jquery.validate/1.7/jquery.validate.min.js" type="text/javascript"></script> <script src="../../Scripts/MicrosoftAjax.js" type="text/javascript"></script> <script src="../../Scripts/MicrosoftMvcAjax.js" type="text/javascript"></script> <script src="../../Scripts/MicrosoftMvcValidation.js" type="text/javascript"></script> then I get the following error: > Error: Type._registerScript is not a > function Source File: > http://ajax.microsoft.com/ajax/beta/0911/MicrosoftAjaxTemplates.js > Line: 1 and: > Error: Sys.get("$listings") is null > Source File: > http://localhost:12370/Listings Line: > 76 Here's the code calling the dataview: $(document).ready(function () { LoadMap(); Sys.require([Sys.components.dataView, Sys.scripts.jQuery], function() { $("#listings").dataView(); Sys.get("$listings").set_data(listings.Data); updateMap(listings.Data); }); }); I would really appreciate any help with this one. Thanks! UPDATE: I've tried moving around the order of the last 4 script tags, but to no avail.

• Server side aggregation using Spring MVC Controllers

  - by Venu

  Hi! We have a web site with multiple pages each with lot of AJAX calls. All the Ajax calls go to a data proxy layer written in Spring 3 MVC application. In order to reduce the load on the server we are planning to aggregate calls on the client and send to the proxy layer. For ex: we have two calls /controller1/action1 and /controller2/action2 in different controllers. I want to write an aggregate controller and call it from the client instead of making two calls to the individual controllers. Something like /aggregatecontroller/aggregate (and we will post the information regarding which calls are being aggregated and required parameters). Is there any way we can call another controller/action from a controller/action and get output? The flow will be something like this: a. Call /aggregatecontroller/aggregate with info regd call1 and call2 b. aggregate action understands that it needs to aggregate call1 and call2 c. it calls /controller1/action1 and gets the response d. it calls /controller2/action2 and gets the response e. it merges both in a json response and sends it back to browser. Please let me know if you have any suggestion regd how to do this or if you think there is a better approach to do the server side aggregation. Thanks for your time.

• Client side page call/scrape?

  - by Silvre

  Here is the problem: I have a web application - a frequently changing notification system - that runs on a series of local computers. The application refreshes every couple of seconds to display the new information. The computers only display info, and do not have keyboards or ANY input device. The issue is that if the connection to the server is lost (say updates are installed and a server must be rebooted), a page not found error is displayed). We must then either reboot all computers that are running this app, OR add a keyboard and refresh the browser, OR try to access each computer remotely and refresh the browser. None of these are good options and result in a lot of frustration. I cannot change the actual application OR server environment. So what I need is some way to test the call to the application, and if an error is returned or it times out, continue trying every minute or so until the connection is reestablished. My idea is to create a client-side page scraper, that makes a JS request to the application (which displays basic HTML), and can run locally on the machine, no server required. If the scrape returns the correct content, it displays it. If not it continues to request the page until the actual page content is returned. Is this possible? What is the best way to do it?

• Client-side user custom CSS single file for overriding multiple domains

  - by Cawas

  This is for using in Safari, though it could probably be used on Firefox as well. In Chrome you have to add a plugin anyway (which generally allow for custom CSS per domain), and Opera already allows this to be done without needing any CSS. But while it's for customizing on the client-side, it's also a pure CSS question. So I'm using no plugins here. So, again, I got a custom CSS code (easily) working for all domains. Now I want to get specify CSS code for each domain. All with just 1 CSS file that's being loaded by Safari. Over the web and googling, I've found two ways to supposedly do this, but none actually worked. They're both documented on userstyles.com: @-moz-document domain("your-domain.com") { }. This would be perfect, since I can have several tags like that and just choose which style will be loaded for which domain. It just doesn't work. @namespace is quite confusing and I've tried every variation I could think of. None worked.

• Different routing rules for a particular user using firewall mark and ip rule

  - by Paul Crowley

  Running Ubuntu 12.10 on amd64. I'm trying to set up different routing rules for a particular user. I understand that the right way to do this is to create a firewall rule that marks the packets for that user, and add a routing rule for that mark. Just to get testing going, I've added a rule that discards all packets as unreachable: # ip rule 0: from all lookup local 32765: from all fwmark 0x1 unreachable 32766: from all lookup main 32767: from all lookup default With this rule in place and all firewall chains in all tables empty and policy ACCEPT, I can still ping remote hosts just fine as any user. If I then add a rule to mark all packets and try to ping Google, it fails as expected # iptables -t mangle -F OUTPUT # iptables -t mangle -A OUTPUT -j MARK --set-mark 0x01 # ping www.google.com ping: unknown host www.google.com If I restrict this rule to the VPN user, it seems to have no effect. # iptables -t mangle -F OUTPUT # iptables -t mangle -A OUTPUT -j MARK --set-mark 0x01 -m owner --uid-owner vpn # sudo -u vpn ping www.google.com PING www.google.com (173.194.78.103) 56(84) bytes of data. 64 bytes from wg-in-f103.1e100.net (173.194.78.103): icmp_req=1 ttl=50 time=36.6 ms But it appears that the mark is being set, because if I add a rule to drop these packets in the firewall, it works: # iptables -t mangle -A OUTPUT -j DROP -m mark --mark 0x01 # sudo -u vpn ping www.google.com ping: unknown host www.google.com What am I missing? Thanks!

• Problem with network policy rule in Network Policy Server

  - by Robert Moir

  Trying to configure RADIUS for a college network, and have run into the following frustration: I can't set an "AND" condition for group membership of authenticated objects in the network policy rules, e.g. I'm trying to create a NPS rule that says, essentially "IF user is a member of [list of user groups] And is authenticating from a computer in [wireless computer group] then allow access. The screenshot above is the rule I am having trouble with. It does not work as written. The rule underneath it, which is identical in every aspect except the conditions rule, does work. I've tried changing the non-working rule to define each set of groups as "Windows group" rather than specifically as machine and user groups, with no change. With the "faulty" rule enabled and the working one disabled, any attempt to login with a valid account from a machine that is in the wireless computers group gives a 6273 audit event in the windows event log: Reason code 66 - "the user attempted to use an authentication method that is not enabled on the matching network policy". Disabling the "faulty" rule, enabling the other rule and logging in with the same account and computer works just fine.

• client side validation in ascx files (user controls) for asp.net mvc

  hi, I have a logOn forn in ascx files and I render it as partial. How I can add a clinet side validation to this form, have any idea ?

• Javascript self contained sandbox events and client side stack

  - by amnon

  I'm in the process of moving a JSF heavy web application to a REST and mainly JS module application . I've watched "scalable javascript application architecture" by Nicholas Zakas on yui theater (excellent video) and implemented much of the talk with good success but i have some questions : I found the lecture a little confusing in regards to the relationship between modules and sandboxes , on one had to my understanding modules should not be effected by something happening outside of their sandbox and this is why they publish events via the sandbox (and not via the core as they do access the core for hiding base libary) but each module in the application gets a new sandbox ? , shouldn't the sandbox limit events to the modoules using it ? or should events be published cross page ? e.g. : if i have two editable tables but i want to contain each one in a different sandbox and it's events effect only the modules inside that sandbox something like messabe box per table which is a different module/widget how can i do that with sandbox per module , ofcourse i can prefix the events with the moduleid but that creates coupling that i want to avoid ... and i don't want to package modules toghter as one module per combination as i already have 6-7 modules ? while i can hide the base library for small things like id selector etc.. i would still like to use the base library for module dependencies and resource loading and use something like yui loader or dojo.require so in fact i'm hiding the base library but the modules themself are defined and loaded by the base library ... seems a little strange to me libraries don't return simple js objects but usualy wrap them e.g. : u can do something like $$('.classname').each(.. which cleans the code alot , it makes no sense to wrap the base and then in the module create a dependency for the base library by executing .each but not using those features makes a lot of code written which can be left out ... and implemnting that functionality is very bug prone does anyonen have any experience with building a front side stack of this order ? how easy is it to change a base library and/or have modules from different libraries , using yui datatable but doing form validation with dojo ... ? some what of a combination of 2+4 if u choose to do something like i said and load dojo form validation widgets for inputs via yui loader would that mean dojocore is a module and the form module is dependant on it ? Thanks .

• How to update off screen bitmap in a surfaceview thread

  - by DKDiveDude

  I have a Surfaceview thread and an off canvas texture bitmap that is being generated (changed), first row (line), every frame and then copied one position (line) down on regular surfaceview bitmap to make a scrolling effect, and I then continue to draw other things on top of that. Well that is what I really want, however I can't get it to work even though I am creating a separate canvas for off screen bitmap. It is just not scrolling at all. I other words I have a memory bitmap, same size as Surfaceview canvas, which I need to scroll (shift) down one line every frame, and then replace top line with new random texture, and then draw that on regular Surfaceview canvas. Here is what I thought would work; My surfaceChanged where I specify bitmap and canvasses and start thread: @Override public void surfaceCreated(SurfaceHolder holder) { intSurfaceWidth = mSurfaceView.getWidth(); intSurfaceHeight = mSurfaceView.getHeight(); memBitmap = Bitmap.createBitmap(intSurfaceWidth, intSurfaceHeight, Bitmap.Config.ARGB_8888); memCanvas = new Canvas(memCanvas); myThread = new MyThread(holder, this); myThread.setRunning(true); blnPause = false; myThread.start(); } My thread, only showing essential middle running part: @Override public void run() { while (running) { c = null; try { // Lock canvas for drawing c = myHolder.lockCanvas(null); synchronized (mSurfaceHolder) { // First draw off screen bitmap to off screen canvas one line down memCanvas.drawBitmap(memBitmap, 0, 1, null); // Create random one line(row) texture bitmap memTexture = Bitmap.createBitmap(imgTexture, 0, rnd.nextInt(intTextureImageHeight), intSurfaceWidth, 1); // Now add this texture bitmap to top of off screen canvas and hopefully bitmap memCanvas.drawBitmap(textureBitmap, intSurfaceWidth, 0, null); // Draw above updated off screen bitmap to regular canvas, at least I thought it would update (save changes) shifting down and add the texture line to off screen bitmap the off screen canvas was pointing to. c.drawBitmap(memBitmap, 0, 0, null); // Other drawing to canvas comes here } finally { // do this in a finally so that if an exception is thrown // during the above, we don't leave the Surface in an // inconsistent state if (c != null) { myHolder.unlockCanvasAndPost(c); } } } } For my game Tunnel Run. Right now I have a working solution where I instead have an array of bitmaps, size of surface height, that I populate with my random texture and then shift down in a loop for each frame. I get 50 frames per second, but I think I can do better by instead scrolling bitmap.

• HTML client-side portable file generation - no external resources or server calls

  - by awashburn

  I have the following situation: I have set up a series of Cron jobs on an internal company server to run various PHP scripts designed to check data integrity. Each PHP script queries a company database, formats the returned query data into an HTML file containing one or more <tables>, and then mails the HTML file to several client emails as an attachment. From my experience, most of the PHP scripts generate HTML files with only a few tables, however there are a few PHP scripts the create HTML files with around 30 tables. HTML files have been chosen as the distribution format of these scans because HTML makes it easy to view many tables at once in a browser window. I would like to add the functionality for the clients to download a table in the HTML file as a CSV file. I anticipate clients using this feature when they suspect a data integrity issue based on the table data. It would be ideal for them to be able to take the table in question, export the data out to a CSV file, and then study it further. Because need for exporting the data to CSV format is at the discretion of the client, unpredictable as to what table will be under scrutiny, and intermittently used I do not want to create CSV files for every table. Normally creating a CSV file wouldn't be too difficult, using JavaScript/jQuery to preform DOM traversal and generate the CSV file data into a string utilizing a server call or flash library to facilitate the download process; but I have one limiting constraint: The HTML file needs to be "portable." I would like the clients to be able to take their HTML file and preform analysis of the data outside the company intranet. Also it is likely these HTML files will be archived, so making the export functionality "self contained" in the HTML files is a highly desirable feature for the two previous reasons. The "portable" constraint of CSV file generation from a HTML file means: I cannot make a server call. This means ALL the file generation must be done client-side. I want the single HTML file attached to the email to contain all the resources to generate the CSV file. This means I cannot use jQuery or flash libraries to generate the file. I understand, for obvious security reasons, that writing out files to disk using JavaScript isn't supported by any browser. I don't want to create a file without the user knowledge; I would like to generate the file using JavaScript in memory and then prompt the user the "download" the file from memory. I have looked into generating the CSV file as a URI however, according to my research and testing, this approach has a few problems: URIs for files are not supported by IE (See Here) URIs in FireFox saves the file with a random file name and as a .part file As much as it pains me, I can accept the fact the IE<=v9 won't create a URI for files. I would like to create a semi-cross-browser solution in which Chrome, Firefox, and Safari create a URI to download the CSV file after JavaScript DOM traversal compiles the data. My Example Table: <table> <thead class="resulttitle"> <tr> <th style="text-align:center;" colspan="3"> NameOfTheTable</th> </tr> </thead> <tbody> <tr class="resultheader"> <td>VEN_PK</td> <td>VEN_CompanyName</td> <td>VEN_Order</td> </tr> <tr> <td class='resultfield'>1</td> <td class='resultfield'>Brander Ranch</td> <td class='resultfield'>Beef</td> </tr> <tr> <td class='resultfield'>2</td> <td class='resultfield'>Super Tree Produce</td> <td class='resultfield'>Apples</td> </tr> <tr> <td class='resultfield'>3</td> <td class='resultfield'>John's Distilery</td> <td class='resultfield'>Beer</td> </tr> </tbody> <tfoot> <tr> <td colspan="3" style="text-align:right;"> <button onclick="doSomething(this);">Export to CSV File</button></td> </tr> </tfoot> </table> My Example JavaScript: <script type="text/javascript"> function doSomething(inButton) { /* locate elements */ var table = inButton.parentNode.parentNode.parentNode.parentNode; var name = table.rows[0].cells[0].textContent; var tbody = table.tBodies[0]; /* create CSV String through DOM traversal */ var rows = tbody.rows; var csvStr = ""; for (var i=0; i < rows.length; i++) { for (var j=0; j < rows[i].cells.length; j++) { csvStr += rows[i].cells[j].textContent +","; } csvStr += "\n"; } /* temporary proof DOM traversal was successful */ alert("Table Name:\t" + name + "\nCSV String:\n" + csvStr); /* Create URI Here! * (code I am missing) */ /* Approach 1 : Auto-download * downloads CSV data but: * In FireFox downloads as randomCharacers.part instead of name.csv * In Chrome downloads without prompting the user * In Safari opens the files in browser (textfile) */ //var hrefData = "data:text/csv;charset=US-ASCII," + encodeURIComponent(csvStr); //document.location.href = hrefData; /* Approach 2 : Right-Click Save As... */ var hrefData = "data:text/csv;charset=US-ASCII," + encodeURIComponent(csvStr); var fileLink = document.createElement("a"); fileLink.href = hrefData; fileLink.innerHTML = "download"; parentTD = inButton.parentNode; parentTD.appendChild(fileLink); parentTD.removeChild(inButton); } </script> I am looking for an example solution in which the above example table can be downloaded as a CSV file: using a URI the user is prompted to save the file the default filename is the name of the table. code works as described in modern versions of FireFox, Safari, & Chrome I have added a <script> tag with the DOM traversal function doSomething(). The real help I need is with formatting the URI to what I want within the doSomething() function.

• Prevent Looping and Inefficient Rule Executions by C2B2

  This recipe, taken from the recently published Oracle SOA Suite 11g Performance Cookbook gives guidance on how to avoid rule executions that will loop, potentially indefinitely! We’ll use an inbound XML fact and a local RL fact as an example. Getting ready You’ll need access to a SOA composite containing an Oracle Business Rules component in JDeveloper to apply this recipe. We’ll assume you have an XSD schema with an input type RequestInput containing input and bonus String types, and output String value called output in a type ResponseOutput. These aren’t efficient but serve as an example. We’ll step through adding a rule to a composite and creating an RL fact. How to do it... Open a SOA composite. Right click on the Project and select Business Rules (Service Components), use the search box if it is not immediately available. Give the rule a name and click the green plus icon to add the RequestInput to the input and ResponseOutput to the output types. Read the complete article here.

• SWFUpload multiple files server-side handling

  - by Chau

  I need the user to be able to upload multiple files to my server, thus I am using the SWFUpload utility. SWFUpload sends the files one by one, and I need to store them all in the same temporary directory. My ASP.NET handler recieves the files one by one and I can store the file appropriately. My problem is: How do I know which files belong to the same upload? Rephrased, how do I connect the files in my handler?

• jGrowl with asp.net server side processing

  - by Mike

  Hi, Is it possible to create a new thread in asp.net to do some processing, and then upon completion, set a flag so that when the user requests the next page, I can insert some extra text or code to perform some notification? Or if it is possible to send some text to the browser after the request has completed? For example jGrowl would be great to have a notification after some processing has been performed. Thanks

• Client Side Includes on HTML pages

  - by Roy Rico

  Previously I had thought that there were only ways to get content from external URLs into your page. These 2 ways are use an IFRAME or Javascript to include it into your pages. I've just learned of a new way using the tag. <object type="text/html" frameborder="0" data="http://Server/URL/"></object> I have found some content online that confirms this ability, but it doesn't talk much about features such as Accessibility and SEO of the page. Does anyone have any experience with this? Is there any information available regarding using this method and how it effects Accessibility and SEO?

• Client side page permissions - Javascript / jquery / cookies / other?

  - by Ozaki

  TLDR Using plain HTML / Javascript. Want to block access to some pages (doesn't have to be super secure just to stop some peeking eyes). I thought of simply doing this by setting a cookie for each page they are allowed to visit with a value of true but thats a bit messy. Although it would work. Is there a way to set an array of values to a cookie so I can read the cookie and if a name of a page is in there then allow access with an IF statement or so on each of my pages. If they dont have the cookie just to replace my #content (entirepage) to "sorry no" etc. For example: $.cookie("Access","page1, page2, page3",{ expires: 1 }); Am already using JQuery, Jquery cookie. etc. I am up for anyway of doing this cookie idea is just an example So what do you think would be the best / most efficient way of managing this?
