  • Anything wrong with this php code?

    - by Hwang
    1st I have to say I know nothing bout php. I was actually doing my AS3 guest-book and through parts of tutorials from Activetut, I managed to come out a flash guest-book. So the problem now I'm facing is the guest-book could only inject 1 XML data and it will always clear off the old 1, while the flash is still caching on the old XML files. I'd found some other tutorials(which I think its quite hard since i dunno anything about php) and comparing to the php code I'm using, it seems to be extremely short. I have no idea what the code does, so currently I'm not sure whether the problems came from the php or my AS3. <?php if (isset($GLOBALS["HTTP_RAW_POST_DATA"])){ $xml = $GLOBALS["HTTP_RAW_POST_DATA"]; $file = fopen("wish.xml","wb"); fwrite($file, $xml); fclose($file); } ?> and below is my correct XML format: <WISHES> <WISH> <NAME>Test</NAME> <EMAIL>[email protected]</EMAIL> <DATENTIME>2/3/10</DATENTIME> <MESSAGE>Dummy Message</MESSAGE> </WISH> <WISH> <NAME>Test</NAME> <EMAIL>[email protected]</EMAIL> <DATENTIME>2/3/10</DATENTIME> <MESSAGE>Dummy Message</MESSAGE> </WISH> </WISHES> So anyone kind to explain what that php code does? cause it replace my XML with: <WISH> <NAME>Test</NAME> <EMAIL>[email protected]</EMAIL> <DATENTIME>2/3/10</DATENTIME> <MESSAGE>Dummy Message</MESSAGE> </WISH>

  • Visual Studio 2010 Formatting

    - by Rosarch
    I have plenty of experience with Eclipse, and now I'm trying out Visual Studio 2010. I find its formatting somewhat counter-intuitive. Here are some things I'm trying to figure out: Is there a way to select all text and format/indent it properly, like SHIFT+A SHIFT+I in Eclipse? Why is it that when I type a line like if (n == 0) {, as soon as I type the opening brace, the text cursor is moved to the beginning of the line? Is this some productivity speedup I'm failing to see? When I hit ENTER after the aforementioned line, I'd like the closing brace to be put in place automatically for me. How can I do this? I've looked for hotkey documentation, and it's helped a bit, but this still feels clunky to me.

  • Grouping with operands question

    - by Filip
    I have a table: mysql> desc kursy_bid; +-----------+-------------+------+-----+---------+-------+ | Field | Type | Null | Key | Default | Extra | +-----------+-------------+------+-----+---------+-------+ | datetime | datetime | NO | PRI | NULL | | | currency | varchar(6) | NO | PRI | NULL | | | value | varchar(10) | YES | | NULL | | +-----------+-------------+------+-----+---------+-------+ 3 rows in set (0.01 sec) I would like to select some rows from a table, grouped by some time interval (can be one day) where I will have the first row and the last row of the group, the max(value) and min(value). I tried: select datetime, (select value order by datetime asc limit 1) open, (select value order by datetime desc limit 1) close, max(value), min(value) from kursy_bid_test where datetime > '2009-09-14 00:00:00' and currency = 'eurpln' group by month(datetime), day(datetime), hour(datetime); but the output is: | open | close | datetime | max(value) | min(value) | +--------+--------+---------------------+------------+------------+ | 1.4581 | 1.4581 | 2009-09-14 00:00:05 | 4.1712 | 1.4581 | | 1.4581 | 1.4581 | 2009-09-14 01:00:01 | 1.4581 | 1.4581 | As you see open and close is the same (but they shouldn't be). What should be the query to do what I want?

  • How can I avoid garbage collection delays in Java games? (Best Practices)

    - by Brian
    I'm performance tuning interactive games in Java for the Android platform. Once in a while there is a hiccup in drawing and interaction for garbage collection. Usually it's less than one tenth of a second, but sometimes it can be as large as 200ms on very slow devices. I am using the ddms profiler (part of the Android SDK) to search out where my memory allocations come from and excise them from my inner drawing and logic loops. The worst offender had been short loops done like, for(GameObject gob : interactiveObjects) gob.onDraw(canvas); where every single time the loop was executed there was an iterator allocated. I'm using arrays (ArrayList) for my objects now. If I ever want trees or hashes in an inner loop I know that I need to be careful or even reimplement them instead of using the Java Collections framework since I can't afford the extra garbage collection. That may come up when I'm looking at priority queues. I also have trouble where I want to display scores and progress using Canvas.drawText. This is bad, canvas.drawText("Your score is: " + Score.points, x, y, paint); because Strings, char arrays and StringBuffers will be allocated all over to make it work. If you have a few text display items and run the frame 60 times a second that begins to add up and will increase your garbage collection hiccups. I think the best choice here is to keep char[] arrays and decode your int or double manually into it and concatenate strings onto the beginning and end. I'd like to hear if there's something cleaner. I know there must be others out there dealing with this. How do you handle it and what are the pitfalls and best practices you've discovered to run interactively on Java or Android? These gc issues are enough to make me miss manual memory management, but not very much.

  • Django & google openid authentication with socialauth

    - by Zayatzz
    Hello I am trying to use django-socialauth (http://github.com/uswaretech/Django-Socialauth) for authenticating users for my django project. This is firs time working with openid and i've had to figure out how exactly this open id works. I have more or less understood it, by now, but there are few things that elude me. The authentication process starts when the request is put together in in django-socialauth.openid_consumer.views.begin. I can see that the outgoing authentication request is more or less something like this: https://www.google.com/accounts/o8/ud?openid.assoc_handle=AOQobUckRThPUj3K1byG280Aze-dnfc9Iu6AEYaBwvHE11G0zy8kY8GZ& openid.ax.if_available=fname& openid.ax.mode=fetch_request& openid.ax.required=email& openid.ax.type.email=http://axschema.org/contact/email& openid.ax.type.fname=http://example.com/schema/fullname& openid.claimed_id=http://specs.openid.net/auth/2.0/identifier_select& openid.identity=http://specs.openid.net/auth/2.0/identifier_select& openid.mode=checkid_setup&openid.ns=http://specs.openid.net/auth/2.0& openid.ns.ax=http://openid.net/srv/ax/1.0& openid.ns.sreg=http://openid.net/extensions/sreg/1.1& openid.realm=http://localhost/& openid.return_to=http://localhost/social/gmail_login/complete/?janrain_nonce=2010-03-20T11%3A19%3A44ZPZCjNc&openid.sreg.optional=postcode,country,nickname,email This is lot like 2nd example here: http://code.google.com/apis/accounts/docs/OpenID.html#Samples The problem is, that the request, i get back, is nothing like the corresponding example from code.google.com (look at the 3rd example in example responses. Response dict i get is like this: { 'openid.op_endpoint': 'https://www.google.com/accounts/o8/ud', 'openid.sig': 'QWMa4x4ruMUvSCfLwKV6CZRuo0E=', 'openid.ext1.type.email': 'http://axschema.org/contact/email', 'openid.return_to': 'http://localhost/social/gmail_login/complete/?janrain_nonce=2010-03-20T17%3A54%3A06ZHV4cqh', 'janrain_nonce': '2010-03-20T17:54:06ZHV4cqh', 'openid.response_nonce': '2010-03-20T17:54:06ZdC5mMu9M_6O4pw', 'openid.claimed_id': 'https://www.google.com/accounts/o8/id?id=AItOghawkFz0aNzk91vaQWhD-DxRJo6sS09RwM3SE', 'openid.mode': 'id_res', 'openid.ns.ext1': 'http://openid.net/srv/ax/1.0', 'openid.signed': 'op_endpoint,claimed_id,identity,return_to,response_nonce,assoc_handle,ns.ext1,ext1.mode,ext1.type.email,ext1.value.email', 'openid.ext1.value.email': '[email protected]', 'openid.assoc_handle': 'AOQobUfssTJ2IxRlxrIvU4Xg8HHQKKTEuqwGxvwwuPR5rNvag0elGlYL', 'openid.ns': 'http://specs.openid.net/auth/2.0', 'openid.identity': 'https://www.google.com/accounts/o8/id?id=AItOawkghgfhf1FkvaQWhD-DxRJo6sS09RwMKjASE', 'openid.ext1.mode': 'fetch_response'} The socialauth itself has been built to accept my email address this way: elif request.openid and request.openid.ax: email = request.openid.ax.get('email') And obviously this fails. Why i am asking all this is, that perhaps i am doing something wrong and my outgoing request is wrong? Or am i doing all correctly and should change the socialaouth module to accept info in a new way and then commit the change? Alan

  • Java file searching problem

    - by Infinity
    Hello guys! I need to search a file for a word and return the whole line and the line number with this word, then edit the line and write back to the file. Maybe the line number isn't necesary to edit a line in a file. I `was reading after seraching with regexp and opening the filechannel of the file, but I can't get the line number. Maybe there are other better ways to do this. Can you help me how to start this?

  • Cross domain AJAX requests using JQuery and YQL

    - by nav
    Hi , I need to use YQL (Yahoo Query Language) to perform a cross domain ajax request then bind the XML response into a JSON object and retrieve a value from the XML. The link shows how this is done using the YQL service as a proxy for cross domain requests: http://ajaxian.com/archives/using-yql-as-a-proxy-for-cross-domain-ajax For example I'm trying to load the request below: http://query.yahooapis.com/v1/public/yql?q=select%20woeid%20from%20geo.places%20where%20text%20%3D%20%22London%2C%20UK%2C%20UK%22&format=xml After which I need to grab the WOEID value from the XML content returned. Is there a way to use similar code to query the XML data returned? Thanks alot

  • Can't interact with children of an itemRenderer in Flex 4 Gumbo

    - by BlueDude
    I thought this would be pretty easy but I'm running into all sorts of problems with this. I have an ItemRenderer with a an image and two labels. I want to assign separate mouse events to the image and two labels. It seems like the item renderer is treated like a single interactive piece and I haven't found a way to override that. I couldn't even disable the default rollover effect so I had to style the rollOverColor to match my background. Can anyone provide a solution? <s:DataGroup id="browserDataGroup" dataProvider="{model.userBoardList}" verticalCenter="0" left="10" rollOverColor="0x424242" itemRenderer="edu.xxxxx.components.board.BrowserItemRenderer"> <!--itemrenderer code below --> <s:ItemRenderer xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark" xmlns:mx="library://ns.adobe.com/flex/halo" xmlns:ns="library://ns.adobe.com/flex/mx" buttonMode="true" useHandCursor="true" mouseChildren="true"> <s:states> <s:State name="up"/> <s:State name="over"/> </s:states> <s:layout> <s:VerticalLayout gap="2"/> </s:layout> <s:Group> <ns:Image id="image" source="{data.thumbnail}" addedEffect="Fade" completeEffect="Fade" removedEffect="Fade" width="130" height="89" horizontalCenter="0" verticalCenter="0"/> <s:Rect id="imageRect" width="130" height="89"> <s:stroke> <s:SolidColorStroke color="0xFFFFFF" joints="miter" pixelHinting="true"/> </s:stroke> </s:Rect> </s:Group> <s:Label text="{data.title}" color="0xFFFFFF" fontWeight="bold"/> <s:Group> <s:layout> <s:HorizontalLayout gap="3"/> </s:layout> <s:Label text="Edit" color="0xFFFFFF" click="trace('edit');" textDecoration.up="underline" textDecoration.over="none"/> <s:Label text="|" color="0xFFFFFF"/> <s:Label text="Delete" color="0xFFFFFF" click="trace('delete');" textDecoration.up="underline" textDecoration.over="none"/> </s:Group> </s:ItemRenderer>

  • UIActionSheet positioning problem

    - by Dave
    I need to display a pop with a UISwitch and a Done button when user taps on a button and save the state of the switch when the done button in the pop up is tapped. So I use UIActionSheet to do this - sheet = [[UIActionSheet alloc] initWithTitle:@"Switch Setting" delegate:self cancelButtonTitle:nil destructiveButtonTitle:nil otherButtonTitles:@"Done", nil]; theSwitch = [[UISwitch alloc] init]; [sheet addSubview:theSwitch]; [sheet showInView:self.view]; - (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex { if (buttonIndex == actionSheet.firstOtherButtonIndex) { theSwitch .on? NSLog(@"Switch is on") : NSLog(@"Switch if off"); } } All this works great. I have problem with positioning. Unfortunately, I don't have a screen shot at the moment to post here. But the switch appears at the very top on the same line with the Action Sheet title and then below that is the Done button. Please someone help me how to position the switch below the Title and increase the Action Sheet size so it looks neat. I need this asap. Thanks.

  • Help a C# developer understand: What is a monad?

    - by Charlie Flowers
    There is a lot of talk about monads these days. I have read a few articles / blog posts, but I can't go far enough with their examples to fully grasp the concept. The reason is that monads are a functional language concept, and thus the examples are in languages I haven't worked with (since I haven't used a functional language in depth). I can't grasp the syntax deeply enough to follow the articles fully ... but I can tell there's something worth understanding there. However, I know C# pretty well, including lambda expressions and other functional features. I know C# only has a subset of functional features, and so maybe monads can't be expressed in C#. However, surely it is possible to convey the concept? At least I hope so. Maybe you can present a C# example as a foundation, and then describe what a C# developer would wish he could do from there but can't because the language lacks functional programming features. This would be fantastic, because it would convey the intent and benefits of monads. So here's my question: What is the best explanation you can give of monads to a C# 3 developer? Thanks! (EDIT: By the way, I know there are at least 3 "what is a monad" questions already on SO. However, I face the same problem with them ... so this question is needed imo, because of the C#-developer focus. Thanks.)

  • Anyone tried boosting Windows performance by putting Swap File on a Flash drive?

    - by Clay Nichols
    Windows Vista introduced ReadyBoost which lets you use a Flash drive as a third (after RAM and HD) type of memory. It occurred to me that I could boost peformance on an old PC here w/ Win XP (32 bit, max'd at 4GB RAM) by putting it's swap file (page file) on a flash drive. (Now, before anyone comments: apparently Flash drives (10-30MB/s transfer rates) are slower than HDD (100+ MB/s) (I'm asking that as a separate question on this forum).

  • Can you share offline files cache with two user accounts?

    - by Joel Coehoorn
    I have a new laptop that I use for both home and work. It runs windows 7 ultimate, and is joined to the domain at work. It is okay to use this laptop for both work and personal activities, and I even have an account set up on the local machine in addition to the work domain account specifically for this to help keep the two separate. At home, I have a file server that I use to share files and printers with my wife's laptop, this new laptop, and my old desktop which will now become the family machine. My mp3 library is on there, among other things. What I want to do is use the windows Offline Files feature to keep a synced copy of my music library on the laptop. That part is easy. What's tricky is that I want to share this offline cache between both the local account on the laptop and my work domain account. I could do them both separately, but then I have two copies of a very large music library stored locally. This also means twice the sync burden, when the domain account is rarely connected to the file share. I really want to be able to sync from the local machine account only, and have the domain account be able to use the synced files. I know where the offline file cache is kept (\Windows\CSC) and I can find the cached files (not encrypted), but permissions on the cache are setup weird, and so using that cache directly is not trivial. Any ideas appreciated.

  • applet communication using post method

    - by mithun1538
    I have an applet that is communicating with a servlet. I am communicating with the servlet using POST method. My problem is how do I send parameters to the servlet. Using GET method, this is fairly simple ( I just append the parameters to the URL after a ?). But using POST method how do I send the parameters, so that in the servlet side, I can use the statement : message = req.getParameter("msg"); In the applet side, I establish POST method connection as follows : URL url = new URL(getCodeBase(), "servlet"); URLConnection con = url.openConnection(); con.setDoInput(true); con.setDoOutput(true); con.setUseCaches(false); con.setRequestProperty("Content-Type","application/octet-stream");
