  • Java Stop Server Thread

    - by ikurtz
    the following code is server code in my app: private int serverPort; private Thread serverThread = null; public void networkListen(int port){ serverPort = port; if (serverThread == null){ Runnable serverRunnable = new ServerRunnable(); serverThread = new Thread(serverRunnable); serverThread.start(); } else { } } public class ServerRunnable implements Runnable { public void run(){ try { //networkConnected = false; //netMessage = "Listening for Connection"; //networkMessage = new NetworkMessage(networkConnected, netMessage); //setChanged(); //notifyObservers(networkMessage); ServerSocket serverSocket = new ServerSocket(serverPort, backlog); commSocket = serverSocket.accept(); serverSocket.close(); serverSocket = null; //networkConnected = true; //netMessage = "Connected: " + commSocket.getInetAddress().getHostAddress() + ":" + //commSocket.getPort(); //networkMessage = new NetworkMessage(networkConnected, netMessage); //setChanged(); //notifyObservers(networkMessage); } catch (IOException e){ //networkConnected = false; //netMessage = "ServerRunnable Network Unavailable"; //System.out.println(e.getMessage()); //networkMessage = new NetworkMessage(networkConnected, netMessage); //setChanged(); //notifyObservers(networkMessage); } } } The code sort of works i.e. if im attempting a straight connection both ends communicate and update. The issue is while im listening for a connection if i want to quit listening then the server thread continues running and causes problems. i know i should not use .stop() on a thread so i was wondering what the solution would look like with this in mind? EDIT: commented out unneeded code.

  • Changing the admin edit window display values

    - by Henri
    I have a database table with e.g. a weight value e.g. CREATE TABLE product ( id SERIAL NOT NULL, product_name item_name NOT NULL, . . weight NUMERIC(7,3), -- the weight in kg . . CONSTRAINT PK_product PRIMARY KEY (id) ); This results is the model: class Product(models.Model): . weight = models.DecimalField(max_digits=7, decimal_places=3, blank=True, null=True) . I store the weight in kg's, i.e. 1 kg is stores as 1, 0.1 kg or 100g is stored as 0.1 To make it easier for the user, I display the weight in the Admin list display in grams by specifying: def show_weight(self): if self.weight: weight_in_g = self.weight * 1000 return '%0f' % weight_in_g So if a product weighs e.g. 0.5 kg and is stored in the database as such, the admin list display shows 500 Is there also a way to alter the number shown in the 'Change product' window. This window now shows the value extracted from the database, i.e. 0.5. This will confuse a user when I tell him with the help_text to enter the number in g, while seeing the number of kgs. Before saving the product I override save as follows: def save(self): if self.weight: self.weight = self.weight / 1000 This converts the number entered in grams to kgs.

  • How can I load txt file from internet into my jsf app?

    - by Elena
    Hi all! It's me again) I have another problem. I want to load file (for example - txt) from web. I tried to use the next code in my managed bean: public void run() { try { URL url = new URL(this.filename); URLConnection connection = url.openConnection(); bufferedReader = new BufferedReader(new InputStreamReader(connection.getInputStream())); if (bufferedReader == null) { return; } System.out.println("wwwwwwwwwwwwwwwwwwwww"); String str = bufferedReader.readLine(); System.out.println("qqqqqqqqqqqqqqqqqqqqqqq = " + str); while (bufferedReader.readLine() != null) { System.out.println("---- " + bufferedReader.readLine()); } } catch(MalformedURLException mue) { System.out.println("MalformedURLException in run() method"); mue.printStackTrace(); } catch(IOException ioe) { System.out.println("IOException in run() method"); ioe.printStackTrace(); } finally { try { bufferedReader.close(); } catch(IOException ioe) { System.out.println("UOException wile closing BufferedReader"); ioe.printStackTrace(); } } } public String doFileUpdate() { String str = FacesContext.getCurrentInstance().getExternalContext().getRequestServletPath(); System.out.println("111111111111111111111 str = " + str); str = "http://narod.ru/disk/20957166000/test.txt.html";//"http://localhost:8080/sfront/files/test.html"; System.out.println("222222222222222222222 str = " + str); FileUpdater fileUpdater = new FileUpdater(str); fileUpdater.run(); return null; } But the BufferedReader returns the html code of the current page, where i am trying to call managed bean's method. It's very strange thing - I have googled and none have had this problem. Maybe I do something wrong, maybe there us a simplest way to load file into web (jsf) app not using net API. Any ideas? Thanks very much for help! With best wishes)

  • Cursor while loop returning every value but the last

    - by LordSnoutimus
    Hello, I am using a while loop to iterate through a cursor and then outputing the longitude and latitude values of every point within the database. For some reason it is not returning the last (or first depending on if I use Cursor.MoveToLast) set of longitude and latitude values in the cursor. Here is my code: public void loadTrack() { SQLiteDatabase db1 = waypoints.getWritableDatabase(); Cursor trackCursor = db1.query(TABLE_NAME, FROM, "trackidfk=1", null, null, null,ORDER_BY); trackCursor.moveToFirst(); while (trackCursor.moveToNext()) { Double lat = trackCursor.getDouble(2); Double lon = trackCursor.getDouble(1); //overlay.addGeoPoint( new GeoPoint( (int)(lat*1E6), (int)(lon*1E6))); System.out.println(lon); System.out.println(lat); } } From this I am getting: 04-02 15:39:07.416: INFO/System.out(10551): 3.0 04-02 15:39:07.416: INFO/System.out(10551): 5.0 04-02 15:39:07.416: INFO/System.out(10551): 4.0 04-02 15:39:07.416: INFO/System.out(10551): 5.0 04-02 15:39:07.416: INFO/System.out(10551): 5.0 04-02 15:39:07.416: INFO/System.out(10551): 5.0 04-02 15:39:07.416: INFO/System.out(10551): 4.0 04-02 15:39:07.416: INFO/System.out(10551): 4.0 04-02 15:39:07.416: INFO/System.out(10551): 3.0 04-02 15:39:07.416: INFO/System.out(10551): 3.0 04-02 15:39:07.416: INFO/System.out(10551): 2.0 04-02 15:39:07.416: INFO/System.out(10551): 2.0 04-02 15:39:07.493: INFO/System.out(10551): 1.0 04-02 15:39:07.493: INFO/System.out(10551): 1.0 7 Sets of values, where I should be getting 8 sets.

  • How make this special many2many fields validation using Django ORM?

    - by e-satis
    I have the folowing model: class Step(models.Model): order = models.IntegerField() latitude = models.FloatField() longitude = models.FloatField() date = DateField(blank=True, null=True) class Journey(models.Model): boat = models.ForeignKey(Boat) route = models.ManyToManyField(Step) departure = models.ForeignKey(Step, related_name="departure_of", null=True) arrival = models.ForeignKey(Step, related_name="arrival_of", null=True) I would like to implement the following check: # If a there is less than one step, raises ValidationError. routes = tuple(self.route.order_by("date")) if len(routes) <= 1: raise ValidationError("There must be at least two setps in the route") # save the first and the last step as departure and arrival self.departure = routes[0] self.arrival = routes[-1] # departure and arrival must at least have a date if not (self.departure.date or self.arrival.date): raise ValidationError("There must be an departure and an arrival date. " "Please set the date field for the first and last Step of the Journey") # departure must occurs before arrival if not (self.departure.date > self.arrival.date): raise ValidationError("Departure must take place the same day or any date before arrival. " "Please set accordingly the date field for the first and last Step of the Journey") I tried to do that by overloading save(). Unfortunately, Journey.route is empty in save(). What's more, Journey.id doesn't exists yet. I didn't try django.db.models.signals.post_save but suppose it will fail because Journey.route is empty as well (when does this get filled anyway?). I see a solution in django.db.models.signals.m2m_changed but there are a lot of steps (thousands), and I want to avoid to perform an operation for every single of them.

  • Extension Method for copying properties form object to another, with first attempt

    - by James
    Hi All, Im trying to write an extension method that I can use to copy values from one object property to another object of a different type, as long as the property names and types match exactly. This is what I have: public static T CopyFrom<T>(this T toObject, object fromObject) { var fromObjectType = fromObject.GetType(); var fromProperties = fromObjectType.GetProperties(); foreach (PropertyInfo toProperty in toObject.GetType().GetProperties()) { PropertyInfo fromProperty = fromObjectType.GetProperty(toProperty.Name); if (fromProperty != null) // match found { // check types var fromType = fromProperty.PropertyType.UnderlyingSystemType; var toType = toProperty.PropertyType.UnderlyingSystemType; if (toType.IsAssignableFrom(fromType)) { toProperty.SetValue(toObject, fromProperty.GetValue(fromObject, null), null); } } } return toObject; } This is working great for non boxed types, but Nullable<T> returns false when I call toType.IsAssignableFrom(fromType) because its type is Nullable<T> and is not the underlying type T. I read here that GetType() should unbox the Nullable<T> so it returns T but if I call that on PropertyInfo.PropertyType I get ReflectedMemberInfo and not the type T im looking for. I think im missing something obvious here, so I thought I would throw it open to SO to get some advice. Anyone have any ideas? Thanks, Jamee

  • 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

  • Entity framework memory leak after detaching newly created object

    - by Tom Peplow
    Hi, Here's a test: WeakReference ref1; WeakReference ref2; TestRepositoryEntitiesContainer context; int i = 0; using (context = GetContext<TestRepositoryEntitiesContainer>()) { context.ObjectMaterialized += (o, s) => i++; var item = context.SomeEntities.Where(e => e.SomePropertyToLookupOn == "some property").First(); context.Detach(item); ref1 = new WeakReference(item); var newItem = new SomeEntity {SomePropertyToLookupOn = "another value"}; context.SomeEntities.AddObject(newItem); ref2 = new WeakReference(newItem); context.SaveChanges(); context.SomeEntities.Detach(newItem); newItem = null; item = null; } context = null; GC.Collect(); Assert.IsFalse(ref1.IsAlive); Assert.IsFalse(ref2.IsAlive); First assert passes, second fails... I hope I'm missing something, it is late... But it appears that detaching a fetched item will actually release all handles on the object letting it be collected. However, for new objects something keeps a pointer and creates a memory leak. NB - this is EF 4.0 Anyone seen this before and worked around it? Thanks for your help! Tom

  • Generate jpeg compressed Tiff using RGB colorspace (using Java + JAI)

    - by nOiSe gaTe
    I'm trying to make tiled pyramidal tiffs from master tiff images using Java (JAI 1.1.3 + imageIO). The problem is: I NEED to make tiff files compressed in jpeg with RGB photometric interpretation and no matter what I try, the image still faces YCbCr photometric interpretation. Note: if I change compression type (eg. LZW or Deflate) I can get RGB colorspace but, as I said, I need jpeg compression. Except this detail the tiled PTiff I create it's ok, so I think it's better to focus the attention on simple compression step (uncompressed tiff -- jpeg tiff) this may be a basic example (removing any check to make it more readable) // reading MASTER BufferedImage img = ImageIO.read(uncompressedTiff); ImageOutputStream ios=null; ImageWriter writer=null; ios = ImageIO.createImageOutputStream(outFile); Iterator <ImageWriter> writers = ImageIO.getImageWritersByFormatName("tiff"); writer = writers.next(); // saving and compression params writer.setOutput(ios); ImageWriteParam param = writer.getDefaultWriteParam(); param.setCompressionMode(ImageWriteParam.MODE_EXPLICIT); param.setCompressionType("JPEG"); param.setCompressionQuality(0.8f); param.setTilingMode(ImageWriteParam.MODE_EXPLICIT); param.setTiling(256, 256, 0, 0); IIOMetadata metadata = getWriteMD(writer, param); // writing writer.write(metadata, new IIOImage(img, null, metadata), param); in getWriteMD method: .... TIFFTag photoInterp = base.getTag(BaselineTIFFTagSet.TAG_PHOTOMETRIC_INTERPRETATION); TIFFField fieldPhotoInter = new TIFFField(photoInterp, BaselineTIFFTagSet.PHOTOMETRIC_INTERPRETATION_RGB); .... here is the full version of getWriteMD()

  • Show me your Linq to SQL architectures!

    - by Brad Heller
    I've been using Linq to SQL for a new implementation that I've been working on. I have about 5000 lines of code and am a little ways from a solid demo. I've been pretty satisfied with Linq to SQL so far -- the tools are excellent and pretty painless and it allows you to get a DAL up and running quickly. That said, there are some major draw backs that I just keep hitting over and over again. Namely how to handle separation of concerns between my DAL and my business layer and juggling that with different data contexts. Here is the architecture I've been using: My repositories do all my data access and they return Linq to SQL objects. Each of my Linq to SQL objects implements an IDetachable interface. A typical implementation looks like this: partial class PaymentDetail : IDetachable { #region IDetachable Members public bool IsAttached { get { return PropertyChanging != null; } } public void Detach() { if (IsAttached) { PropertyChanged = null; PropertyChanging = null; Transaction.Detach(); } } #endregion } Every time I do a DAL operation in my repository I "detach" when I'm done with the object (and it should theoretically detach from any child objects) to remove the DataContext's context. Like I said, this works pretty well, but there are some edge cases that seem to be a big pain in the ass. For instance, my Transaction object has many PaymentDetails. Even when there are no PaymentDetails in that collection it's still attached to the DataContext's context! Thus, if I try to update (I update by Attach()ing to the object and then SubmitChanges()) I get that dreaded "An attempt has been made to Attach or Add an entity that is not new, perhaps having been loaded from another DataContext. This is not supported." message. Anyway, I'm starting to doubt that this technology was a good gamble. Has anyone got a decent architecture that they're willing to share? I'd really love to use this technology but I feel like I spend 1/3 of my time just debugging is retarded quirks!

  • Does using ReadDirectoryChangesW require administrator rights?

    - by Alex Jenter
    The MSDN says that using ReadDirectoryChangesW implies the calling process having the Backup and Restore priviliges. Does this mean that only process launched under administrator account will work correctly? I've tried the following code, it fails to enable the required privileges when running as a restricted user. void enablePrivileges() { enablePrivilege(SE_BACKUP_NAME); enablePrivilege(SE_RESTORE_NAME); } void enablePrivilege(LPCTSTR name) { HANDLE hToken; DWORD status; if (::OpenProcessToken(::GetCurrentProcess(), TOKEN_ADJUST_PRIVILEGES, &hToken)) { TOKEN_PRIVILEGES tp = { 1 }; if( ::LookupPrivilegeValue(NULL, name, &tp.Privileges[0].Luid) ) { tp.Privileges[0].Attributes = SE_PRIVILEGE_ENABLED; BOOL result = ::AdjustTokenPrivileges(hToken, FALSE, &tp, 0, NULL, NULL); verify (result != FALSE); status = ::GetLastError(); } ::CloseHandle(hToken); } } Am I doing something wrong? Is there any workaround for using ReadDirectoryChangesW from a non-administrator user account? It seems that the .NET's FileSystemWatcher can do this. Thanks!

  • Help Needed With AJAX Script

    Hello All I am working on an AJAX script but am having difficulties. First, here is the script: var xmlHttp; function GetXmlHttpObject(){ var objXMLHttp=null if (window.XMLHttpRequest){ objXMLHttp=new XMLHttpRequest() } else if (window.ActiveXObject){ objXMLHttp=new ActiveXObject("Microsoft.XMLHTTP") } return objXMLHttp } function retrieveData(){ var jBossServer = new Array(); jBossServer[0] = "d01"; jBossServer[1] = "d02"; jBossServer[2] = "p01"; jBossServer[3] = "p02"; for(var i=0; i<jBossServer.length; i++){ xmlHttp = GetXmlHttpObject(); if (xmlHttp == null){ alert ("Something weird happened ..."); return; } var url="./retrieveData.php"; url = url + "?jBossID=" + jBossServer[i]; url = url + "&sid=" + Math.random(); xmlHttp.open("GET",url,true); xmlHttp.onreadystatechange = updateMemory; xmlHttp.send(null); } } function updateMemory(){ if (xmlHttp.readyState == 4 || xmlHttp.readyState == "complete"){ aggregateArray = new Array(); aggregateArray = xmlHttp.responseText.split(','); for(var i=0; i<aggregateArray.length; i++){ alert(aggregateArray[i]); } return; } } The "retrieveData.php" page will return data that looks like this: d01,1 MB,2 MB,3 MB They relate to my 4 servers d01, d02, p01, and p02 (dev and prod). What I am doing is scraping the memory information from http://127.0.0.1:8080/web-console/ServerInfo.jsp I want to save code so I attempted to put the AJAX xmlHttp call into a loop, but I don't think it is working. All I ever get back is the information for "p02" four times. Am I able to do what I want or do I need four different functions for each server (i.e., xmlHttpServer01, xmlHttpServer02, xmlHttpServer03, xmlHttpServer04)? Thank you all for reading, have a good day. :)

  • Using CallExternalMethodActivity/HandleExternalEventActivity in StateMachine

    - by AngrySpade
    I'm attempting to make a StateMachine execute some database action between states. So I have a "starting" state that uses CallExternalMethodActivity to call a "BeginExecuteNonQuery" function on an class decorated with ExternalDataExchangeAttribute. After that it uses a SetStateActivity to change to an "ending" state. The "ending" state uses a HandleExternalEventActivity to listen to a "EndExecuteNonQuery" event. I can step through the local service, into the "BeginExecuteNonQuery" function. The problem is that the "EndExecuteNonQuery" is null. public class FailoverWorkflowController : IFailoverWorkflowController { private readonly WorkflowRuntime workflowRuntime; private readonly FailoverWorkflowControlService failoverWorkflowControlService; private readonly DatabaseControlService databaseControlService; public FailoverWorkflowController() { workflowRuntime = new WorkflowRuntime(); workflowRuntime.WorkflowCompleted += workflowRuntime_WorkflowCompleted; workflowRuntime.WorkflowTerminated += workflowRuntime_WorkflowTerminated; ExternalDataExchangeService dataExchangeService = new ExternalDataExchangeService(); workflowRuntime.AddService(dataExchangeService); databaseControlService = new DatabaseControlService(); workflowRuntime.AddService(databaseControlService); workflowRuntime.StartRuntime(); } ... } ... public void BeginExecuteNonQuery(string command) { Guid workflowInstanceID = WorkflowEnvironment.WorkflowInstanceId; ThreadPool.QueueUserWorkItem(delegate(object state) { try { int result = ExecuteNonQuery((string)state); EndExecuteNonQuery(null, new ExecuteNonQueryResultEventArgs(workflowInstanceID, result)); } catch (Exception exception) { EndExecuteNonQuery(null, new ExecuteNonQueryResultEventArgs(workflowInstanceID, exception)); } }, command); } What am I doing wrong with my implementation? -Stan

  • Using Build Manager Class to Load ASPX Files and Populate its Controls

    - by Sandhurst
    I am using BuildManager Class to Load a dynamically generated ASPX File, please note that it does not have a corresponding .cs file. Using Following code I am able to load the aspx file, I am even able to loop through the control collection of the dynamically created aspx file, but when I am assigning values to controls they are not showing it up. for example if I am binding the value "Dummy" to TextBox control of the aspx page, the textbox remains empty. Here's the code that I am using protected void Page_Load(object sender, EventArgs e) { LoadPage("~/Demo.aspx"); } public static void LoadPage(string pagePath) { // get the compiled type of referenced path Type type = BuildManager.GetCompiledType(pagePath); // if type is null, could not determine page type if (type == null) throw new ApplicationException("Page " + pagePath + " not found"); // cast page object (could also cast an interface instance as well) // in this example, ASP220Page is a custom base page System.Web.UI.Page pageView = (System.Web.UI.Page)Activator.CreateInstance(type); // call page title pageView.Title = "Dynamically loaded page..."; // call custom property of ASP220Page //pageView.InternalControls.Add( // new LiteralControl("Served dynamically...")); // process the request with updated object ((IHttpHandler)pageView).ProcessRequest(HttpContext.Current); LoadDataInDynamicPage(pageView); } private static void LoadDataInDynamicPage(Page prvPage) { foreach (Control ctrl in prvPage.Controls) { //Find Form Control if (ctrl.ID != null) { if (ctrl.ID.Equals("form1")) { AllFormsClass cls = new AllFormsClass(); DataSet ds = cls.GetConditionalData("1"); foreach (Control ctr in ctrl.Controls) { if (ctr is TextBox) { if (ctr.ID.Contains("_M")) { TextBox drpControl = (TextBox)ctr; drpControl.Text = ds.Tables[0].Rows[0][ctr.ID].ToString(); } else if (ctr.ID.Contains("_O")) { TextBox drpControl = (TextBox)ctr; drpControl.Text = ds.Tables[1].Rows[0][ctr.ID].ToString(); } } } } } } }

  • Why does a conditional not affect query speed?

    - by Telos
    I have a stored procedure that was taking a "long" period of time to execute. The query only needs to return data in one case, so I figured I could check for that case and just return before hitting the actual query. The only problem is that it still takes the same amount of time to execute with an if statement. I have verified that the code inside the if is not executing, and that if I replace the complex query with a simple select the speed is fine... so now I'm confused. Why is the query being slowed down by code that doesn't get executed when the conditional is false? Here's the query itself: ALTER PROCEDURE [dbo].[pr_cbc_GetCokeInfo] @pa_record int, @pb_record int AS BEGIN SET NOCOUNT ON; declare @ticketRec int SELECT @ticketRec = TicketRecord FROM eservice_live..v_sdticket where TicketRecord=@pa_record AND serviceCompanyID = 1139 AND @pb_record IS NULL if @ticketRec IS NULL return select record = null, doc_ref = @pa_record, memo_type = 'I', memo = 'Bottler: ' + isnull(Bottler, '') + ' ' + 'Sales Loc: ' + isnull(SalesLocation, '') + ' ' + 'Outlet Desc: ' + isnull(OutletDesc, '') + ' ' + 'City: ' + isnull(OutletCity, '') + ' ' + 'EquipNo: ' + isnull(EquipNo, '') + ' ' + 'SerialNo: ' + isnull(SerialNo, '') + ' ' + 'PhaseNo: ' + isnull(cast(PhaseNo as varchar(255)), '') + ' ' + 'StaticIP: ' + isnull(StaticIP, '') + ' ' + 'Air Card: ' + isnull(AirCard, '') FROM eservice_live..v_SDExtendedInfoField ef JOIN eservice_live..CokeSNList csl ON ef.valueText=csl.SerialNo where ef.docType='CLH' AND ef.docref = @ticketRec AND ef.ExtendedDocNumber=5 SET NOCOUNT OFF; END

  • Image Masking Problem

    - by Adnan Sohail
    Hi I am doing image masking. First I was using C*GImageMaskCreate()* function for masking but now I am using your solution which you had posted for masking. My problem is it works fine on simulator but on device it is not transparent and it gives rectangle of mask image at background. The following is my code. Now tell me what I have to do? Thanks. CGContextRef mainViewContentContext; CGColorSpaceRef colorSpace; UIImage *orgImage=[UIImage imageNamed:@"orgimage.png"]; CGImageRef img = [orgImage CGImage]; colorSpace = CGColorSpaceCreateDeviceRGB(); mainViewContentContext = CGBitmapContextCreate (NULL, width, height, 8, 0, colorSpace, kCGImageAlphaPremultipliedLast); CGColorSpaceRelease(colorSpace); if (mainViewContentContext==NULL) return NULL; CGRect subImageRect; CGImageRef tileImage; subImageRect = CGRectMake(xCord,yCord,width,height); tileImage = CGImageCreateWithImageInRect(img,subImageRect); CGImageRef maskImage = mask_image.CGImage; CGContextClipToMask(mainViewContentContext, CGRectMake(0, 0, width, height), maskImage); CGContextDrawImage(mainViewContentContext, CGRectMake(0, 0, width, height), tileImage); CGImageRef mainViewContentBitmapContext = CGBitmapContextCreateImage(mainViewContentContext); CGContextRelease(mainViewContentContext); UIImage *theImage = [UIImage imageWithCGImage:mainViewContentBitmapContext]; CGImageRelease(mainViewContentBitmapContext);

  • Run AppleScript with Elevated Privileges from Objective C

    - by cygnl7
    I'm attempting to execute an uninstaller (written in AppleScript) through AuthorizationExecuteWithPrivileges. I'm setting up my rights after creating an empty auth ref like so: char *tool = "/usr/bin/osascript"; AuthorizationItem items = {kAuthorizationRightExecute, strlen(tool), tool, 0}; AuthorizationRights rights = {sizeof(items)/sizeof(AuthorizationItem), &items}; AuthorizationFlags flags = kAuthorizationFlagDefaults | kAuthorizationFlagExtendRights | kAuthorizationFlagPreAuthorize | kAuthorizationFlagInteractionAllowed; status = AuthorizationCopyRights(authorizationRef, &rights, NULL, flags, NULL); Later I call: status = AuthorizationExecuteWithPrivileges(authorizationRef, tool, kAuthorizationFlagDefaults, (char *const *)args, NULL); On Snow Leopard this works fine, but on Leopard I get the following in syslog.log: Apr 19 15:30:09 hostname /usr/bin/osascript[39226]: OpenScripting.framework - 'gdut' event blocked in process with mixed credentials (issetugid=0 uid=501 euid=0 gid=20 egid=20) Apr 19 15:30:12: --- last message repeated 1 time --- ... Apr 19 15:30:12 hostname [0x0-0x2e92e9].com.example.uninstaller[39219]: /var/folders/vm/vmkIi0nYG8mHMrllaXaTgk+++TI/-Tmp-/TestApp_tmpfiles/Uninstall.scpt: Apr 19 15:30:12 hostname [0x0-0x2e92e9].com.example.uninstaller[39219]: execution error: «constant afdmasup» doesn’t understand the «event earsffdr» message. (-1708) After researching this for a few hours my first guess is that Leopard somehow doesn't want to do what I'm doing because it knows it's in a setuid situation and blocks calls that ask about user-specific things in the applescript. Am I going about this all wrong? I just want to run the equivalent of "sudo /usr/bin/osascript ..." Edit: FWIW, the first line that causes the "execution error" is: set userAppSupportPath to (POSIX path of (path to application support folder from user domain)) However, even with an empty script (on run argv, end run and that's it) I still get the 'gdut' message.

  • call lynx from jsp script

    - by Piero
    Hi, I have an execute(String cmd) in a jsp script that calls the exec method from the Runtime class. It works when I call a local command, like a php script stored on the server. for example: /usr/bin/php /path/to/php/script arg1 arg2 So I guess my execute command is ok, since it is working with that. Now when I try to call lynx, the text-based web browser, it does not work. If I call it in a terminal, it works fine: /usr/bin/lynx -dump -accept_all_cookies 'http://www.someurl.net/?arg1=1&arg2=2' But when I call this from my execute command, nothing happens... Any idea why? This is my execute method: public String execute(String cmd){ Runtime r = Runtime.getRuntime(); Process p = null; String res = ""; try { p = r.exec(cmd); InputStreamReader isr = new InputStreamReader(p.getInputStream()); BufferedReader br = new BufferedReader(isr); String line = null; //out.println(res); while ((line = br.readLine()) != null) { res += line; } p.waitFor(); } catch (Exception e) { res += e; } System.out.println(p.exitValue()); return res; }

  • How can I work around SQL Server - Inline Table Value Function execution plan variation based on par

    - by Ovidiu Pacurar
    Here is the situation: I have a table value function with a datetime parameter ,lest's say tdf(p_date) , that filters about two million rows selecting those with column date smaller than p_date and computes some aggregate values on other columns. It works great but if p_date is a custom scalar value function (returning the end of day in my case) the execution plan is altered an the query goes from 1 sec to 1 minute execution time. A proof of concept table - 1K products, 2M rows: CREATE TABLE [dbo].[POC]( [Date] [datetime] NOT NULL, [idProduct] [int] NOT NULL, [Quantity] [int] NOT NULL ) ON [PRIMARY] The inline table value function: CREATE FUNCTION tdf (@p_date datetime) RETURNS TABLE AS RETURN ( SELECT idProduct, SUM(Quantity) AS TotalQuantity, max(Date) as LastDate FROM POC WHERE (Date < @p_date) GROUP BY idProduct ) The scalar value function: CREATE FUNCTION [dbo].[EndOfDay] (@date datetime) RETURNS datetime AS BEGIN DECLARE @res datetime SET @res=dateadd(second, -1, dateadd(day, 1, dateadd(ms, -datepart(ms, @date), dateadd(ss, -datepart(ss, @date), dateadd(mi,- datepart(mi,@date), dateadd(hh, -datepart(hh, @date), @date)))))) RETURN @res END Query 1 - Working great SELECT * FROM [dbo].[tdf] (getdate()) The end of execution plan: Stream Aggregate Cost 13% <--- Clustered Index Scan Cost 86% Query 2 - Not so great SELECT * FROM [dbo].[tdf] (dbo.EndOfDay(getdate())) The end of execution plan: Stream Aggregate Cost 4% <--- Filter Cost 12% <--- Clustered Index Scan Cost 86%
