  • Django: Named URLs / Same Template, Different Named URL

    - by TheLizardKing
    I have a webapp that lists all of my artists, albums and songs when the appropriate link is clicked. I make extensive use of generic views (object_list/detail) and named urls but I am coming across an annoyance. I have three templates that pretty much output the exact same html that look just like this: {% extends "base.html" %} {% block content %} <div id="content"> <ul id="starts-with"> {% for starts_with in starts_with_list %} <li><a href="{% url song_list_x starts_with %}">{{ starts_with|upper }}</a></li> {% endfor %} </ul> <ul> {% for song in songs_list %} <li>{{ song.title }}</li> {% endfor %} </ul> </div> {% endblock content %} My artist and album template look pretty much the same and I'd like to combine the three template's into one. The fact that my variables start with song can easily be changed to the default obj. It's my <ul id="starts-with"> named url I don't know how to correct. Obviously I want it to link to a specific album/artist/song using the named urls in my urls.py but I don't know how to make it context aware. Any suggestions? urlpatterns = patterns('tlkmusic.apps.tlkmusic_base.views', # (r'^$', index), url(r'^artists/$', artist_list, name='artist_list'), url(r'^artists/(?P<starts_with>\w)/$', artist_list, name='artist_list_x'), url(r'^artist/(?P<artist_id>\d+)/$', artist_detail, name='artist_detail'), url(r'^albums/$', album_list, name='album_list'), url(r'^albums/(?P<starts_with>\w)/$', album_list, name='album_list_x'), url(r'^songs/$', song_list, name='song_list'), url(r'^songs/(?P<starts_with>\w)/$', song_list, name='song_list_x'), )

  • Cannot hide a UIButton - Please help!

    - by Neurofluxation
    Hey again, I have the following code: visitSite.hidden = YES; For some reason, when I click a UIButton and call this piece of code, the visitSite button does not hide. The code is within this block: -(IBAction)welcomeButtonPressed:(id)sender { [UIButton beginAnimations:@"welcomeAnimation" context:NULL]; [UIButton setAnimationDuration:1.5]; [UIButton SetAnimationDidStopSelector:@selector(nowHideThisSiteButton:finished:context:)]; [UIButton setAnimationTransition:UIViewAnimationTransitionCurlUp forView:self.view cache:YES]; ((UIView *)sender).hidden = YES; [UIButton commitAnimations]; } and the stop selector below: -(void)nowHideThisSiteButton:(NSString *)animationID finished:(BOOL *)finished context:(void *)context { visitSite.hidden = YES; } I've also tried [visitSite setHidden:YES]; and that fails as well. ALSO I've noticed that the setAnimationDidStopSelector does not get called at all. Also, visitSite (when NSLogged) equals: <UIButton: 0x1290f0; frame = (0 0; 320 460); opaque = NO; autoresize = RM+BM; layer = <CALayer: 0x1290f0>> visitSite.hidden (when NSLogged) equals: NULL Any more ideas? :(

  • Save has_and_belongs_to_many link in basic RoR app

    - by Stéphane V
    I try to learn the has_and_belongs_to_many relationship between my 2 fresh new and simple models Product and Author, where a Product can have many authors and where author can have a lots of products. I wrote this : class Author < ActiveRecord::Base has_and_belongs_to_many :products end class Product < ActiveRecord::Base has_and_belongs_to_many :authors end In the partial form of view for the products, I have : <p>Products</p> <%= collection_select(:product, :author_ids, @authors, :id, :name, :prompt => " ", :multiple => true) %> but when I hit the update button, I get this strange message I can't resolve myself : NoMethodError in ProductsController#update undefined method `reject' for "1":String Rails.root: /home/stephane/www/HABTM Application Trace | Framework Trace | Full Trace app/controllers/products_controller.rb:63:in block in update' app/controllers/products_controller.rb:62:inupdate' Request Parameters: {"utf8"="✓", "_method"="put", "authenticity_token"="2GlTssOFjTVZ9BikrIFgx22cdTOIJuAB70liYhhLf+4=", "product"={"title"="Le trésor des Templiers", "original_title"="", "number"="1", "added_by"="", "author_ids"="1"}, "commit"="Update Product", "id"="1"} What's wrong ? Is there a problem with :product_ids... I saw on internet I had to pu a "s" but I'm not sure of what it represents.... How can I link the table authors_products to the key which is given back by the drop-down menu ? (here "author_ids"="1") Thx !

  • can a OOM be caused by not finding enough contiguous memory?

    - by raticulin
    I start some java code with -Xmx1024m, and at some point I get an hprof due to OOM. The hprof shows just 320mb, and give me a stack trace: at java.util.Arrays.copyOfRange([CII)[C (Arrays.java:3209) at java.lang.String.<init>([CII)V (String.java:215) at java.lang.StringBuilder.toString()Ljava/lang/String; (StringBuilder.java:430) ... This comes from a large string I am copying. I remember reading somewhere (cannot find where) what happened is these cases is: process still has not consumed 1gb of memory, is way below even if heap still below 1gb, it needs some amount of memory, and for copyOfRange() it has to be continuous memory, so even if it is not over the limit yet, it cannot find a large enough piece of memory on the host, it fails with an OOM. I have tried to look for doc on this (copyOfRange() needs a block of continuous memory), but could not find any. The other possible culprit would be not enough permgen memory. Can someone confirm or refute the continuous memory hypothesis? Any pointer to some doc would help too.

  • Help me understand entity framework 4 caching for lazy loading

    - by Chris
    I am getting some unexpected behaviour with entity framework 4.0 and I am hoping someone can help me understand this. I am using the northwind database for the purposes of this question. I am also using the default code generator (not poco or self tracking). I am expecting that anytime I query the context for the framework to only make a round trip if I have not already fetched those objects. I do get this behaviour if I turn off lazy loading. Currently in my application I am breifly turning on lazy loading and then turning it back off so I can get the desired behaviour. That pretty much sucks, so please help. Here is a good code example that can demonstrate my problem. Public Sub ManyRoundTrips() context.ContextOptions.LazyLoadingEnabled = True Dim employees As List(Of Employee) = context.Employees.Execute(System.Data.Objects.MergeOption.AppendOnly).ToList() 'makes unnessesary round trip to the database, I just loaded the employees' MessageBox.Show(context.Employees.Where(Function(x) x.EmployeeID < 10).ToList().Count) context.Orders.Execute(System.Data.Objects.MergeOption.AppendOnly) For Each emp As Employee In employees 'makes unnessesary trip to database every time despite orders being pre loaded.' Dim i As Integer = emp.Orders.Count Next End Sub Public Sub OneRoundTrip() context.ContextOptions.LazyLoadingEnabled = True Dim employees As List(Of Employee) = context.Employees.Include("Orders").Execute(System.Data.Objects.MergeOption.AppendOnly).ToList() MessageBox.Show(employees.Where(Function(x) x.EmployeeID < 10).ToList().Count) For Each emp As Employee In employees Dim i As Integer = emp.Orders.Count Next End Sub Why is the first block of code making unnessesary round trips?

  • Print a string that contains a certain pattern in Java

    - by jjpotter
    I am trying to find a regular expression within a line of a .csv file, so I can eventually save all the matches to another file, and lose all the other junk. So a line in my file might look like: MachineName,User,IP,VariableData,Location The VariableData is what I want to match, and if there's a match, print the line. I am using a pattern for this because I only want 3 out of 10 of variations of VariableData, and out of those 3, they are numbered differently(example, "pc104, pccrt102, pccart65"). I am trying to do this using the Scanner Class and keeping it simple as possible so I can understand it. Here is where I was heading with this...(the pattern isn't complete, just have it like this for testing). import java.io.File; import java.util.Scanner; import java.util.regex.Pattern; public class pcv { public static void main(String[] args) { File myFile = new File("c:\\temp\\report.csv"); Pattern myPat = Pattern.compile("pc"); try{ Scanner myScan = new Scanner(myFile); while(myScan.hasNext()){ if(myScan.hasNext(myPat)){ System.out.println("Test"); } } }catch(Exception e){ } } } This code loops, im guessing the .hasNext() methods are resetting themselves. I've played around with the Matcher class a little bit, but only found a way to match the expression but not get the whole line. My other throught was maybe somehow count the line that contains the pattern, then go back and print the line that corresponds to the counts.

  • How to add share menu item to Gallery by code

    - by Anthony
    I know how to implement this issue by Menuifest.xml, see also: Google Android Developer Group related issue But my question is how to add share menu of Gallery by java code not Menuifest.xml. My code is as below: public class MyActivity extends Activity { private static final String TAG = "MyActivity"; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); IntentFilter intentFilter = new IntentFilter(); intentFilter.addAction(Intent.ACTION_SEND); intentFilter.addCategory(Intent.CATEGORY_DEFAULT); try { intentFilter.addDataType("image/*"); } catch (MalformedMimeTypeException e) { Log.e(TAG, e.toString()); } Intent x = registerReceiver(new BroadcastReceiver() { public void onReceive(Context context, Intent intent) { Log.d(TAG, "Received intent "+intent); intent.setComponent(new ComponentName(context, Uploader.class)); startActivity(intent); } }, intentFilter); if (x==null) Log.i(TAG, "failed to regist a receiver"); else Log.i(TAG, "registed a receiver successfully"); // ... But registerReceiver always return null, and there is no menu added to Gallery's Share. Thank you. Anthony Xu

  • Writing XML in different character encodings with Java

    - by Roman Myers
    I am attempting to write an XML library file that can be read again into my program. The file writer code is as follows: XMLBuilder builder = new XMLBuilder(); Document doc = builder.build(bookList); DOMImplementation impl = doc.getImplementation(); DOMImplementationLS implLS = (DOMImplementationLS) impl.getFeature("LS", "3.0"); LSSerializer ser = implLS.createLSSerializer(); String out = ser.writeToString(doc); //System.out.println(out); try{ FileWriter fstream = new FileWriter(location); BufferedWriter outwrite = new BufferedWriter(fstream); outwrite.write(out); outwrite.close(); }catch (Exception e){ } The above code does write an xml document. However, in the XML header, it is an attribute that the file is encoded in UTF-16. when i read in the file, i get the error: "content not allowed in prolog" this error does not occur when the encoding attribute is manually changed to UTF-8. I am trying to get the above code to write an XML document encoded in UTF-8, or successfully parse a UTF-16 file. the code for parsing in is DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance(); DocumentBuilder loader = factory.newDocumentBuilder(); Document document = loader.parse(filename); the last line returns the error.

  • Why is it assumed that send may return with less than requested data transmitted on a blocking socke

    - by Ernelli
    The standard method to send data on a stream socket has always been to call send with a chunk of data to write, check the return value to see if all data was sent and then keep calling send again until the whole message has been accepted. For example this is a simple example of a common scheme: int send_all(int sock, unsigned char *buffer, int len) { int nsent; while(len 0) { nsent = send(sock, buffer, len, 0); if(nsent == -1) // error return -1; buffer += nsent; len -= nsent; } return 0; // ok, all data sent } Even the BSD manpage mentions that ...If no messages space is available at the socket to hold the message to be transmitted, then send() normally blocks... Which indicates that we should assume that send may return without sending all data. Now I find this rather broken but even W. Richard Stevens assumes this in his standard reference book about network programming, not in the beginning chapters, but the more advanced examples uses his own writen (write all data) function instead of calling write. Now I consider this still to be more or less broken, since if send is not able to transmit all data or accept the data in the underlying buffer and the socket is blocking, then send should block and return when the whole send request has been accepted. I mean, in the code example above, what will happen if send returns with less data sent is that it will be called right again with a new request. What has changed since last call? At max a few hundred CPU cycles have passed so the buffer is still full. If send now accepts the data why could'nt it accept it before? Otherwise we will end upp with an inefficient loop where we are trying to send data on a socket that cannot accept data and keep trying, or else? So it seems like the workaround, if needed, results in heavily inefficient code and in those circumstances blocking sockets should be avoided at all an non blocking sockets together with select should be used instead.

  • Firefox 3.6 and CSS difference from previous versions of Firefox 3.5 and back?

    - by American Yak
    So, in upgrading to Firefox 3.6, the CSS broke on input boxes. The padding has increased -- it might also be the font-size is somehow behaving different. Wondering if anyone else has seen this problem yet. Can't quite figure it out. HTML CODE: <form> <fieldset> <label for="inputField">Label</label> <input type="text" id="inputField" /> </fieldset> </form> CSS CODE: form fieldset label { display:block; font-size:1.2em; font-weight:bold; padding:12px 9px; } #jumptoBox fieldset input { background: url("../images/input.png") no-repeat scroll left top transparent; font-size: 1.2em; padding: 4px 5px 16px; width: 99px; height: 29px; } (Image dimensions: 109 width x 34 height) So one thing to note, the fix (as outlined below) includes removing the height, or at least setting it to auto, and then compensating for it by using padding (a fix that bothers me on many levels, but we'll set that aside for now). BUT webkit seems to have its own problems with this now, since it wants to center the text vertically (ignoring any evidence of line-height) according to the height of everything. In other words, if you want the text vertically closer to the top, I haven't been able to figure out a way to do that. Ideas?

  • Finding a 3rd party QWidget with injected code & QWidget::find(hwnd)

    - by David Menard
    Hey, I have a Qt Dll wich I inject into a third-party Application using windows detours library: if(!DetourCreateProcessWithDll( Path, NULL, NULL, NULL, TRUE, CREATE_DEFAULT_ERROR_MODE | CREATE_SUSPENDED, NULL, NULL, &si, &pi, "C:\\Program Files\\Microsoft Research\\Detours Express 2.1\\bin\\detoured.dll", "C:\\Users\\Dave\\Documents\\Visual Studio 2008\\Projects\\XOR\\Debug\\XOR.dll", NULL)) and then I set a system-wide hook to intercept window creation: HHOOK h_hook = ::SetWindowsHookEx(WH_CBT, (HOOKPROC)CBTProc, Status::getInstance()->getXORInstance(), 0); Where XOR is my programs name, and Status::getInstance() is a Singleton where I keep globals. In my CBTProc callback, I want to intercept all windows that are QWidgets: HWND hwnd= FindWindow(L"QWidget", NULL); which works well, since I get a corresponding HWND (I checked with Spy++) Then, I want to get a pointer to the QWidget, so I can use its functions: QWidget* q = QWidget::find(hwnd); but here's the problem, the returned pointer is always 0. Am I not injecting my code into the process properly? Or am I not using QWidget::find() as I should? Thanks, Dave EDIT:If i change the QWidget::find() function to an exported function of my DLL, after setting the hooks (so I can set and catch a breakpoint), QWidgetPrivate::mapper is NULL.

  • What are the drawbacks of using PHP to create variables in my CSS stylesheet?

    - by Greg
    One significant drawback of CSS is that one can't use variables. For example, I'd like to use variables to control the location of imported CSS, and it would be awesome to create variables for colors that are used repeatedly in a design. One approach is to use a PHP file for the CSS stylesheet. In other words, create a "style.php" with... <?php header("Content-type: text/css"); ?> ...at the top of the file, and then link to it using... <link href="style.php" rel="stylesheet" type="text/css" /> ...in any file that uses these styles. So what's the catch? I think it might be performance -- I did a few quick experiments in Firefox/Firebug and as one would expect, the CSS stylesheet is cached, but the PHP stylesheet isn't. So we're paying the price of an additional GET. The other annoying thing is that TextMate does not syntax highlight properly for CSS in a .php file. Are there other drawbacks? Have you used this approach, and if so, would you recommend it?

  • CSS style to create an HTML with an image on left and input text boxes on right that fills all space

    - by dafi
    I need to create an HTML page (a JqueryUI dialog but this isn't the problem) containing an image on left (size is fixed to 75x75) and on right some input text boxes, input boxes must resize to all remaining space. You can see an example at http://img683.imageshack.us/img683/5412/19483174.jpg The problem is that when I resize the dialog controls move under image as shown at http://img510.imageshack.us/img510/4817/44749696.jpg How can I resolve this problem in all browser and if possible using only CSS? Below I show my HTML code and the CSS I'm using HTML code <div id="dialog-form" title="Modify Post"> <form action=""> <fieldset> <img id="dialog-modify-thumb" src="http://dummyimage.com/75x75/000/fff" alt="" width="75" height="75"/> <div id="dialog-modify-controls"> <label for="dialog-modify-caption">Caption</label> <input type="text" name="dialog-modify-caption" id="dialog-modify-caption"/> <br/> <label for="dialog-modify-tags">Tags</label> <input type="text" name="dialog-modify-tags" id="dialog-modify-tags"/> <br/> <label for="dialog-modify-publish-date">Publish Date</label> <input type="text" name="dialog-modify-publish-date" id="dialog-modify-publish-date"/> </div> </fieldset> </form> </div> The CSS #dialog-modify-thumb { margin-right: 3px; border: 1px solid; display: block; float:left; } #dialog-form input[type='text'] { width: 100%; } #dialog-modify-controls { float: right; width:100%; }

  • VB .Net - Reflection: Reflected Method from a loaded Assembly executes before calling method. Why?

    - by pu.griffin
    When I am loading an Assembly dynamically, then calling a method from it, I appear to be getting the method from Assembly executing before the code in the method that is calling it. It does not appear to be executing in a Serial manner as I would expect. Can anyone shine some light on why this might be happening. Below is some code to illustrate what I am seeing, the code from the some.dll assembly calls a method named PerformLookup. For testing I put a similar MessageBox type output with "PerformLookup Time: " as the text. What I end up seeing is: First: "PerformLookup Time: 40:842" Second: "initIndex Time: 45:873" Imports System Imports System.Data Imports System.IO Imports Microsoft.VisualBasic.Strings Imports System.Reflection Public Class Class1 Public Function initIndex(indexTable as System.Collections.Hashtable) As System.Data.DataSet Dim writeCode As String MessageBox.Show("initIndex Time: " & Date.Now.Second.ToString() & ":" & Date.Now.Millisecond.ToString()) System.Threading.Thread.Sleep(5000) writeCode = RefreshList() End Function Public Function RefreshList() As String Dim asm As System.Reflection.Assembly Dim t As Type() Dim ty As Type Dim m As MethodInfo() Dim mm As MethodInfo Dim retString as String retString = "" Try asm = System.Reflection.Assembly.LoadFrom("C:\Program Files\some.dll") t = asm.GetTypes() ty = asm.GetType(t(28).FullName) 'known class location m = ty.GetMethods() mm = ty.GetMethod("PerformLookup") Dim o as Object o = Activator.CreateInstance(ty) Dim oo as Object() retString = mm.Invoke(o,Nothing).ToString() Catch Ex As Exception End Try return retString End Function End Class

  • Automatic multi-page multi-column flowing text with QtWebkit (HTML/CSS/JS -> PDF)

    - by Peter Boughton
    I have some HTML documents that are converted to PDF, using software that renders using QtWebkit (not sure which version). Currently, the documents have specific tags to split into columns and pages - so whenever the wording changes, it is a manual time-consuming process to move these tags so that the columns and pages fit. Can anyone provide a way to have text auto-wrapped into the next column/page (as appropriate) when it reaches the bottom of the current container? Any HTML, CSS or JS supported by QtWebkit is ok (assuming it works in the PDF converter). (I have tested the webkit-column-* in CSS3 and it appears QtWebkit does not support this.) To make things more exciting, it also needs to: - put a header at the top of each page, with page X of Y numbering; - if an odd number of pages, add a blank page at the end (with no header); - have the ability to say "don't break inside this block" or "don't break after this header" I have put some quick example initial markup and target markup to help explain what I'm trying to do. (The actual documents are far more complicated than that, but I need a simple proof-of-concept before I attack the real ones.) Any suggestions? Update: I've got a partially working solution using Aaron's "filling up" suggestion - I'll post more details in a bit.

  • Deadlock in ThreadPoolExecutor

    - by Vitaly
    Encountered a situation when ThreadPoolExecutor is parked in execute(Runnable) function while all the ThreadPool threads are waiting in getTask func, workQueue is empty. Does anybody have any ideas? The ThreadPoolExecutor is created with ArrayBlockingQueue, corePoolSize == maximumPoolSize = 4 [Edit] To be more precise, the thread is blocked in ThreadPoolExecutor.exec(Runnable command) func. It has the task to execute, but doesn't do it. [Edit2] The executor is blocked somewhere inside the working queue (ArrayBlockingQueue). [Edit3] The callstack: thread = front_end(224) at sun.misc.Unsafe.park(Native methord) at java.util.concurrent.locks.LockSupport.park(LockSupport.java:158) at java.util.concurrent.locks.AbstractQueuedSynchronizer.parkAndCheckInterrupt(AbstractQueuedSynchronizer.java:747) at java.util.concurrent.locks.AbstractQueuedSynchronizer.acquireQueued(AbstractQueuedSynchronizer.java:778) at java.util.concurrent.locks.AbstractQueuedSynchronizer.acquire(AbstractQueuedSynchronizer.java:1114) at java.util.concurrent.locks.ReentrantLock$NonfairSync.lock(ReentrantLock.java:186) at java.util.concurrent.locks.ReentrantLock.lock(ReentrantLock.java:262) at java.util.concurrent.ArrayBlockingQueue.offer(ArrayBlockingQueue.java:224) at java.util.concurrent.ThreadPoolExecutor.execute(ThreadPoolExecutor.java:653) at net.listenThread.WorkersPool.execute(WorkersPool.java:45) at the same time the workQueue is empty (checked using remote debug) [Edit4] Code working with ThreadPoolExecutor: public WorkersPool(int size) { pool = new ThreadPoolExecutor(size, size, IDLE_WORKER_THREAD_TIMEOUT, TimeUnit.SECONDS, new ArrayBlockingQueue<Runnable>(WORK_QUEUE_CAPACITY), new ThreadFactory() { @NotNull private final AtomicInteger threadsCount = new AtomicInteger(0); @NotNull public Thread newThread(@NotNull Runnable r) { final Thread thread = new Thread(r); thread.setName("net_worker_" + threadsCount.incrementAndGet()); return thread; } }, new RejectedExecutionHandler() { public void rejectedExecution(@Nullable Runnable r, @Nullable ThreadPoolExecutor executor) { Verify.warning("new task " + r + " is discarded"); } }); } public void execute(@NotNull Runnable task) { pool.execute(task); } public void stopWorkers() throws WorkersTerminationFailedException { pool.shutdownNow(); try { pool.awaitTermination(THREAD_TERMINATION_WAIT_TIME, TimeUnit.SECONDS); } catch (InterruptedException e) { throw new WorkersTerminationFailedException("Workers-pool termination failed", e); } } }

  • a facebook app question

    - by Robert
    I have written a small app and put it on facebook. I got an application ID and secret. Then I wrote the following script to access my app (just as told on the facebook page). <?php require './src/facebook.php'; $facebook = new Facebook(array( 'appId' => 'xxxx', 'secret' => 'xxxx', 'cookie' => true, // enable optional cookie support )); try { $me = $facebook->api('/me'); } catch (FacebookApiException $e) { error_log($e); } if ($facebook->getSession()) { echo '<a href="' . $facebook->getLogoutUrl() . '">Logout</a>'; } else { echo '<a href="' . $facebook->getLoginUrl() . '">Login</a>'; } ?> Then I started running this script. It prompted me with the login link, then took me to the facebook login page. However, after I enter my facebook login details, I get this error page: Error. API Error Code: 100 API Error Description: Invalid parameter Error Message: next is not owned by the application. Could anyone help me a little bit please, I am really confused here about what's going on.

  • GD PHP Base64 Picture (png) error

    - by hogofwar
    This is part of my code: $con = mysql_connect("localhost","username","passs"); if (!$con) { die('Could not connect: ' . mysql_error()); } mysql_select_db("database", $con); if(mysql_num_rows(mysql_query("SELECT name FROM xbox_user WHERE name = '$user'"))){ // Code inside if block if userid is already there $result = mysql_query("SELECT name FROM xbox_user WHERE name = '$user'"); while($row = mysql_fetch_array($result)) { if ($row['date'] > $row['date']+100){ $src = imagecreatefrompng($result['XboxInfo']['TileUrl']); $base64= base64_encode(file_get_contents($result['XboxInfo']['TileUrl'])); $date = date("Ymd"); mysql_query("UPDATE xbox_user SET date = '$date' SET avatar = '$base64' WHERE name = '$user'"); }else{ $encode = $row['avatar']; //echo $encode; $rand = rand(1, 1337); file_put_contents('/tmp/'.$rand.'.png', base64_decode($row['avatar'])); //ERROR LINE $src = imagecreatefrompng('/tmp/'.$rand.'.png'); unlink('/tmp/'.$rand.'.png'); } } }else{ $src = imagecreatefrompng($result['XboxInfo']['TileUrl']); $base64= base64_encode(file_get_contents($result['XboxInfo']['TileUrl'])); $date = date("Ymd"); mysql_query("INSERT INTO xbox_user (name, avatar, date) VALUES ('$user', '$base64', '$date')"); } It comes up with multiple errors but I feel this one should be addressed first as the other could just be caused by the first error: Warning: imagecreatefrompng() [function.imagecreatefrompng]: '/tmp/628.png' is not a valid PNG file in /home/nah/public_html/experiment/xbox/draw3.php on line 60 It also does create an entry in my mysql DB

  • SharePoint Visual web part and Oracle connection problem

    - by Rishi
    Hi, I'm trying to build a "visual web part" for SharePoint 2010 which should connect to Oracle table and display records on SharePoint page.For development, Oracle 11g client (with ODP.net) ,SharePoint server 2010, Visual Studio 2010 and Oracle 10g express all running on my machine. First,I've written sample code in ASP.NET web app to connect my local Oracle table and display data in grid view and it works fine. My code is , OracleConnection con; try { // Connect string constr = "Data Source=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=localhost)(PORT=1521)))(CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=XE)));User Id=SYSTEM; Password=password"; con = new OracleConnection(constr); //Open database connection con.Open(); // Execute a SQL SELECT OracleCommand cmd = new OracleCommand("select * from T_ACTIONPOINTS WHERE AP_STATUS='Active' ", con); OracleDataReader dr = cmd.ExecuteReader(); GridView.DataSource = dr; GridView.DataBind(); GridView.AllowPaging = true; } catch (Exception e) { lblError.Text = e.Message; } Now, I'm trying to create new "SharePoint" visual web part project and using same code and deploying it on my local SP server. But when it runs , I get following error here is my solution explorer, It looks something wrong in compatibility.Can someone point me in right direction ?

  • Connect xampp to MongoDB

    - by Jhonny D. Cano -Leftware-
    Hello I have a xampp 1.7.3 instance running and a MongoDB 1.2.4 server on the same machine. I want to connect them, so I basically have been following this tutorial on php.net, it seems to connect but the cursors are always empty. I don't know what am I missing. Here is the code I am trying. The cursor-valid always says false. thanks <?php $m = new Mongo(); // connect try { $m->connect(); } catch (MongoConnectionException $ex) { echo $ex; } echo "conecta..."; $dbs = $m->listDBs(); if ($dbs == NULL) { echo $m->lastError(); return; } foreach($dbs as $db) { echo $db; } $db = $m->selectDB("CDO"); echo "elige bd..."; $col = $db->selectCollection("rep_consulta"); echo "elige col..."; $rangeQuery = array('id' => array( '$gt' => 100)); $col->insert(array('id' => 456745764, 'nombre' => 'cosa')); $cursor = $col->find()->limit(10); echo "buscando..."; var_dump($cursor); var_dump($cursor->valid()); if ($cursor == NULL) echo 'cursor null'; while($cursor->hasNext()) { $item = $cursor->current(); echo "en while..."; echo $item["nombre"].'...'; } ?> doing this by command line works perfect use CDO db.rep_consulta.find() -- lot of data here
