  • How to listen for file system changes MAC - kFSEventStreamCreateFlagWatchRoot

    - by Cocoa Newbie
    Hi All, I am listening for Directory and disk changes in a COCOA project using FSEvents. I need to get events when a root folder is renamed or deleted. So, I passed kFSEventStreamCreateFlagWatchRoot while creating the FSEventStream.But even if I delete or rename the root folder I am not getting corresponding FSEventStreamEventFlags. Any idea what could possibly be the issue. I am listening for changes in a USB mounted device. I used both FSEventStreamCreate and FSEventStreamCreateRelativeToDevice. One thing I notices is when I try with FSEventStreamCreate I get the following error message while creating FSEventStream: (CarbonCore.framework) FSEventStreamCreate: watch_all_parents: error trying to add kqueue for fd 7 (/Volumes/NO NAME; Operation not supported) But with FSEventStreamCreateRelativeToDevice there are no errors but still not getting kFSEventStreamEventFlagRootChanged in event flags. Also, while creation using FSEventStreamCreateRelativeToDevice apple say's if I want to listen to root path changes pass emty string "". But I am not able to listen to root path changes by passing empty string. But when I pass "/" it works. But even for "/" I do not get any proper FSEventStreamEventFlags. I am pasting the code here: -(void) subscribeFileSystemChanges:(NSString*) path { PRINT_FUNCTION_BEGIN; // if already subscribed then unsubscribe if (stream) { FSEventStreamStop(stream); FSEventStreamInvalidate(stream); /* will remove from runloop */ FSEventStreamRelease(stream); } FSEventStreamContext cntxt = {0}; cntxt.info = self; CFArrayRef pathsToWatch = CFArrayCreate(NULL, (const void**)&path, 1, NULL); stream = FSEventStreamCreate(NULL, &feCallback, &cntxt, pathsToWatch, kFSEventStreamEventIdSinceNow, 1, kFSEventStreamCreateFlagWatchRoot ); FSEventStreamScheduleWithRunLoop(stream, CFRunLoopGetCurrent(), kCFRunLoopDefaultMode); FSEventStreamStart(stream); } call back function: static void feCallback(ConstFSEventStreamRef streamRef, void* pClientCallBackInfo, size_t numEvents, void* pEventPaths, const FSEventStreamEventFlags eventFlags[], const FSEventStreamEventId eventIds[]) {? char** ppPaths = (char**)pEventPaths; int i; for (i = 0; i < numEvents; i++) { NSLog(@"Event Flags %lu Event Id %llu", eventFlags[i], eventIds[i]); NSLog(@"Path changed: %@", [NSString stringWithUTF8String:ppPaths[i]]); } } Thanks a lot in advance.

  • what does this code do?

    - by bstullkid
    It looks like this just sends a ping, but whats the point of that when you can just use ping? int main (int argc, char *argv[]) { unsigned int pid = 0; char buffer[2]; char *args[] = { "/bin/ping", "-c", "5", NULL, NULL }; if (argc != 2) return 0; args[3] = strdup(argv[1]); for (;;) { gets(buffer); /* FTW */ if (buffer[0] == 0x6e) break; switch (pid = fork()) { case -1: printf("Error Forking\n"); exit(255); case 0: execvp(args[0], args); exit(1); default: break; } } return 255; }

  • Programming style: should you return early if a guard condition is not satisfied?

    - by John Topley
    One thing I've sometimes wondered is which is the better style out of the two shown below (if any)? Is it better to return immediately if a guard condition hasn't been satisfied, or should you only do the other stuff if the guard condition is satisfied? For the sake of argument, please assume that the guard condition is a simple test that returns a boolean, such as checking to see if an element is in a collection, rather than something that might affect the control flow by throwing an exception. // Style 1 public SomeType aMethod() { SomeType result = null; if (!guardCondition()) { return result; } doStuffToResult(result); doMoreStuffToResult(result); return result; } // Style 2 public SomeType aMethod() { SomeType result = null; if (guardCondition()) { doStuffToResult(result); doMoreStuffToResult(result); } return result; }

  • Unicode data from NSData to NSString

    - by Jeff
    So if I have NSData from an HTTP request, then I do something like this: NSString *test = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding]; This will result in null if the data contains weird unicode data (title is from reddit): {"title":"click..¦¦me..and..then¦¦________ ¦¦check¦¦_.your...¦¦.__...¦¦____ ¦¦....¦¦¦¦¦¦¦¦¦¦¦¦¦¦....¦¦____ ¦¦¦¦¦¦....¦¦¦¦¦¦....¦¦¦¦¦¦____ ¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦____ ....¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦______ ........¦¦..._recently....¦¦________ ....¦¦....viewed....links....¦¦_____"}, How would I convert the data to a string? Ideally, it would best if the string wasn't null so I could parse it as JSON, but even a lossy conversion is fine with me in these cases. I'm not familiar with unicode (naive American I am), so any enlightenment about that would be a nice bonus :)

  • Same data being returned by linq for 2 different executions of a stored procedure?

    - by Paul
    Hello I have a stored procedure that I am calling through Entity Framework. The stored procedure has 2 date parameters. I supply different argument in the 2 times I call the stored procedure. I have verified using SQL Profiler that the stored procedure is being called correctly and returning the correct results. When I call my method the second time with different arguments, even though the stored procedure is bringing back the correct results, the table created contains the same data as the first time I called it. dtStart = 01/08/2009 dtEnd = 31/08/2009 public List<dataRecord> GetData(DateTime dtStart, DateTime dtEnd) { var tbl = from t in db.SP(dtStart, dtEnd) select t; return tbl.ToList(); } GetData((new DateTime(2009, 8, 1), new DateTime(2009, 8, 31)) // tbl.field1 value = 45450 - CORRECT GetData(new DateTime(2009, 7, 1), new DateTime(2009, 7, 31)) // tbl.field1 value = 45450 - WRONG 27456 expected Is this a case of Entity Framework being clever and caching? I can't see why it would cache this though as it has executed the stored procedure twice. Do I have to do something to close tbl? using Visual Studio 2008 + Entity Framework. I also get the message "query cannot be enumerated more than once" a few times every now and then, am not sure if that is relevant? FULL CODE LISTING namespace ProfileDataService { public partial class DataService { public static List<MeterTotalConsumpRecord> GetTotalAllTimesConsumption(DateTime dtStart, DateTime dtEnd, EUtilityGroup ug, int nMeterSelectionType, int nCustomerID, int nUserID, string strSelection, bool bClosedLocations, bool bDisposedLocations) { dbChildDataContext db = DBManager.ChildDataConext(nCustomerID); var tbl = from t in db.GetTotalConsumptionByMeter(dtStart, dtEnd, (int) ug, nMeterSelectionType, nCustomerID, nUserID, strSelection, bClosedLocations, bDisposedLocations, 1) select t; return tbl.ToList(); } } } /// CALLER List<MeterTotalConsumpRecord> _P1Totals; List<MeterTotalConsumpRecord> _P2Totals; public void LoadData(int nUserID, int nCustomerID, ELocationSelectionMethod locationSelectionMethod, string strLocations, bool bIncludeClosedLocations, bool bIncludeDisposedLocations, DateTime dtStart, DateTime dtEnd, ReportsBusinessLogic.Lists.EPeriodType durMainPeriodType, ReportsBusinessLogic.Lists.EPeriodType durCompareToPeriodType, ReportsBusinessLogic.Lists.EIncreaseReportType rptType, bool bIncludeDecreases) { ///Code for setting properties using parameters.. _P2Totals = ProfileDataService.DataService.GetTotalAllTimesConsumption(_P2StartDate, _P2EndDate, EUtilityGroup.Electricity, 1, nCustomerID, nUserID, strLocations, bIncludeClosedLocations, bIncludeDisposedLocations); _P1Totals = ProfileDataService.DataService.GetTotalAllTimesConsumption(_StartDate, _EndDate, EUtilityGroup.Electricity, 1, nCustomerID, nUserID, strLocations, bIncludeClosedLocations, bIncludeDisposedLocations); PopulateLines() //This fills up a list of objects with information for my report ready for the totals to be added PopulateTotals(_P1Totals, 1); PopulateTotals(_P2Totals, 2); } void PopulateTotals(List<MeterTotalConsumpRecord> objTotals, int nPeriod) { MeterTotalConsumpRecord objMeterConsumption = null; foreach (IncreaseReportDataRecord objLine in _Lines) { objMeterConsumption = objTotals.Find(delegate(MeterTotalConsumpRecord t) { return t.MeterID == objLine.MeterID; }); if (objMeterConsumption != null) { if (nPeriod == 1) { objLine.P1Consumption = (double)objMeterConsumption.Consumption; } else { objLine.P2Consumption = (double)objMeterConsumption.Consumption; } objMeterConsumption = null; } } } }

  • Why JPA injection not works on @PersistentUnit

    - by Dewfy
    Hello colleagues! It is continues of question ( http://stackoverflow.com/questions/2570976/struts-2-bean-is-not-created ) I'm using struts2 + toplink in my very simple web application under Tomcat. On the page I would like use iteration tag. That is why I've declared some factory (SomeFactory) that resolves collection of entities (Entity). Per article: http://download-uk.oracle.com/docs/cd/B32110_01/web.1013/b28221/usclient005.htm#CIHCEHHG the only thing I need is declaration: @PersistenceContext(unitName="name_in_persistence_xml") public class SomeFactory { @PersistenceUnit(unitName="name_in_persistence_xml") EntityManagerFactory emf; public EntityManager getEntityManager() { assert(emf != null); //HERE every time it is null return emf.createEntityManager(); } public Collection<Entity> getAll() { return getEntityManager().createNamedQuery("Entity.findAll").getResultList(); } } What is wrong? May be i miss something in web.xml? How to pre-init toplink for web application to allow injection happen?

I need that 5 records to display after join..... How can I do it?

  • How to get numpad out of "mouse emulation" mode?

    - by Jonik
    My numeric keypad has somehow got into a "mouse emulation" mode where the number keys just move the mouse pointer around (2 = down; 8 = up, 6 = right, etc). Anyone know how to make it work normally again? None of the other numpad keys work either (I first noticed the whole thing when Ctrl + ÷ (numpad division sign) no longer produced "line comment" in IntelliJ IDEA). Toggling num lock doesn't affect this (though the indicator LED works as usual). I'm using GNOME on Lucid Lynx (10.4).

  • Create a nested list

    - by sico87
    How would I create a nested list, I currently have this public function getNav($cat,$subcat){ //gets all sub categories for a specific category if(!$this->checkValue($cat)) return false; //checks data $query = false; if($cat=='NULL'){ $sql = "SELECT itemID, title, parent, url, description, image FROM p_cat WHERE deleted = 0 AND parent is NULL ORDER BY position;"; $query = $this->db->query($sql) or die($this->db->error); }else{ //die($cat); $sql = "SET @parent = (SELECT c.itemID FROM p_cat c WHERE url = '".$this->sql($cat)."' AND deleted = 0); SELECT c1.itemID, c1.title, c1.parent, c1.url, c1.description, c1.image, (SELECT c2.url FROM p_cat c2 WHERE c2.itemID = c1.parent LIMIT 1) as parentUrl FROM p_cat c1 WHERE c1.deleted = 0 AND c1.parent = @parent ORDER BY c1.position;"; $query = $this->db->multi_query($sql) or die($this->db->error); $this->db->store_result(); $this->db->next_result(); $query = $this->db->store_result(); } return $query; } public function getNav($cat=false, $subcat=false){ //gets a list of all categories form this level, if $cat is false it returns top level nav if($cat==false || strtolower($cat)=='all-products') $cat='NULL'; $ds = $this->data->getNav($cat, $subcat); $nav = $ds ? $ds : false; $html = ''; //create html if($nav){ $html = '<ul>'; //var_dump($nav->fetch_assoc()); while($row = $nav->fetch_assoc()){ $url = isset($row['parentUrl']) ? $row['parentUrl'].'/'.$row['url'] : $row['url']; $current = $subcat==$row['url'] ?

  • .NET and XML: How can I read nested namespaces (<abc:xyz:name attr="value"/>)?

    - by Entrase
    Suppose there is an element in XML data: <abc:xyz:name attr="value"/> I'm trying to read it with XmlReader. The problem is that I get XmlException that says The ‘:’ character, hexadecimal value 0x3A, cannot be included in a name I have already declared "abc" namespace. I have also tried adding "abc:xyz" and "xyz" namespaces. But this doesn't help at all. I could replace some text before parsing but there may be some more elegant solution. So what should I do? Here is my code: XmlReaderSettings settings = new XmlReaderSettings() NameTable nt = new NameTable(); XmlNamespaceManager nsmgr = new XmlNamespaceManager(nt); nsmgr.AddNamespace("abc", ""); nsmgr.AddNamespace("xyz", ""); XmlParserContext context = new XmlParserContext(null, nsmgr, null, XmlSpace.None); // So this reader can't read <abc:xyz:name attr="value"/> XmlReader reader = XmlReader.Create(path, settings, context);“

  • forcing Management Studio to use alter table instead of drop/recreate

    - by marco
    Hi! I'm wondering if is there a way to force MSSQL Management Studio to produce a script like this: ALTER TABLE Mytable ADD MyCol bit NOT NULL CONSTRAINT MyColDefault DEFAULT 0 WITH VALUES ALTER TABLE [dbo].Mytable ALTER COLUMN MyCol2 int NULL GO when I alter a very simple property of a column on a table. If I do this in the designer and ask for the produced script, the script doesn't do such simple tasks, but instead copies all the data in a tmp table, drops the original table, renames the tmp table with the original table name. And, of course, drops and recreates every constraint and relationships. Is there any option I can change to change this behaviour? Or, this may be possible, is there some danger I don't see in using the simple ALTER TABLE above? thanks.

  • HttpWebRequest possibly slowing website

    - by Steven Smith
    Using Visual studio 2012, C#.net 4.5 , SQL Server 2008, Feefo, Nopcommerce Hey guys I have Recently implemented a new review service into a current site we have. When the change went live the first day all worked fine. Since then though the sending of sales to Feefo hasnt been working, There are no logs either of anything going wrong. In the OrderProcessingService.cs in Nop Commerce's Service, i call a HttpWebrequest when an order has been confirmed as completed. Here is the code. var email = HttpUtility.UrlEncode(order.Customer.Email.ToString()); var name = HttpUtility.UrlEncode(order.Customer.GetFullName().ToString()); var description = HttpUtility.UrlEncode(productVariant.ProductVariant.Product.MetaDescription != null ? productVariant.ProductVariant.Product.MetaDescription.ToString() : "product"); var orderRef = HttpUtility.UrlEncode(order.Id.ToString()); var productLink = HttpUtility.UrlEncode(string.Format("myurl/p/{0}/{1}", productVariant.ProductVariant.ProductId, productVariant.ProductVariant.Name.Replace(" ", "-"))); string itemRef = ""; try { itemRef = HttpUtility.UrlEncode(productVariant.ProductVariant.ProductId.ToString()); } catch { itemRef = "0"; } var url = string.Format("feefo Url", login, password,email,name,description,orderRef,productLink,itemRef); var request = (HttpWebRequest)WebRequest.Create(url); request.KeepAlive = false; request.Timeout = 5000; request.Proxy = null; using (var response = (HttpWebResponse)request.GetResponse()) { if (response.StatusDescription == "OK") { var stream = response.GetResponseStream(); if(stream != null) { using (var reader = new StreamReader(stream)) { var content = reader.ReadToEnd(); } } } } So as you can see its a simple webrequest that is processed on an order, and all product variants are sent to feefo. Now: this hasnt been happening all week since the 15th (day of the implementation) the site has been grinding to a halt recently. The stream and reader in the the var content is there for debugging. Im wondering does the code redflag anything to you that could relate to the process of website? Also note i have run some SQL statements to see if there is any deadlocks or large escalations, so far seems fine, Logs have also been fine just the usual logging of Bots. Any help would be much appreciated! EDIT: also note that this code is in a method that is called and wrapped in A try catch UPDATE: well forget about the "not sending", thats because i was just told my code was rolled back last week

  • Showing ImageView next to TextView in a ListView

    - by KDEx
    So I have a listview that is displaying correctly. When the item is "turned on" the text is white and when it's turned off it's grey. That part all functions great. However when I add the ImageView into the mix I get a null pointer exception. I don't understand why. I've tried using bitmaps as well and get the same problem. Here is some code: @Override public void bindView(View view, Context context, Cursor cursor) { TextView rRule = (TextView) view.findViewById(R.id.rule_text); TextView rType = (TextView) view.findViewById(R.id.rule_type); ImageView iChecked = (ImageView) view.findViewById(R.id.checkBox); String ruleName = cursor.getString(1); int ruleType = cursor.getInt(2); String ruleEnabled = cursor.getString(3); switch (ruleType) { /*...some irrelevant code */ } if (ruleEnabled.equals("true")) { rRule.setTypeface(null, Typeface.BOLD); rRule.setTextColor(Color.WHITE); iChecked.setVisibility(View.VISIBLE); //line 271 } else if (ruleEnabled.equals("false")) { rRule.setTypeface(null, Typeface.NORMAL); rRule.setTextColor(Color.GRAY); iChecked.setVisibility(View.GONE); } rRule.setText(ruleName); } Per request the error log: (Sorry was under the impression null pointers dont say anything helpful..I know the error is the imageview) 06-29 10:29:02.777: E/AndroidRuntime(29516): FATAL EXCEPTION: main 06-29 10:29:02.777: E/AndroidRuntime(29516): java.lang.NullPointerException 06-29 10:29:02.777: E/AndroidRuntime(29516): at com.company.app.DefaultRulesList$RulesAdapter.bindView(DefaultRulesList.java:271) 06-29 10:29:02.777: E/AndroidRuntime(29516): at com.company.app.DefaultRulesList$RulesAdapter.newView(DefaultRulesList.java:284) 06-29 10:29:02.777: E/AndroidRuntime(29516): at android.widget.CursorAdapter.getView(CursorAdapter.java:246) 06-29 10:29:02.777: E/AndroidRuntime(29516): at android.widget.AbsListView.obtainView(AbsListView.java:2033) 06-29 10:29:02.777: E/AndroidRuntime(29516): at android.widget.ListView.makeAndAddView(ListView.java:1772) 06-29 10:29:02.777: E/AndroidRuntime(29516): at android.widget.ListView.fillDown(ListView.java:672) 06-29 10:29:02.777: E/AndroidRuntime(29516): at android.widget.ListView.fillFromTop(ListView.java:732) 06-29 10:29:02.777: E/AndroidRuntime(29516): at android.widget.ListView.layoutChildren(ListView.java:1625) 06-29 10:29:02.777: E/AndroidRuntime(29516): at android.widget.AbsListView.onLayout(AbsListView.java:1863) 06-29 10:29:02.777: E/AndroidRuntime(29516): at android.view.View.layout(View.java:11278) 06-29 10:29:02.777: E/AndroidRuntime(29516): at android.view.ViewGroup.layout(ViewGroup.java:4224) 06-29 10:29:02.777: E/AndroidRuntime(29516): at android.widget.LinearLayout.setChildFrame(LinearLayout.java:1628) 06-29 10:29:02.777: E/AndroidRuntime(29516): at android.widget.LinearLayout.layoutVertical(LinearLayout.java:1486) 06-29 10:29:02.777: E/AndroidRuntime(29516): at android.widget.LinearLayout.onLayout(LinearLayout.java:1399) 06-29 10:29:02.777: E/AndroidRuntime(29516): at android.view.View.layout(View.java:11278) 06-29 10:29:02.777: E/AndroidRuntime(29516): at android.view.ViewGroup.layout(ViewGroup.java:4224) 06-29 10:29:02.777: E/AndroidRuntime(29516): at android.widget.FrameLayout.onLayout(FrameLayout.java:431) 06-29 10:29:02.777: E/AndroidRuntime(29516): at android.view.View.layout(View.java:11278) 06-29 10:29:02.777: E/AndroidRuntime(29516): at android.view.ViewGroup.layout(ViewGroup.java:4224) 06-29 10:29:02.777: E/AndroidRuntime(29516): at android.widget.LinearLayout.setChildFrame(LinearLayout.java:1628) 06-29 10:29:02.777: E/AndroidRuntime(29516): at android.widget.LinearLayout.layoutVertical(LinearLayout.java:1486) 06-29 10:29:02.777: E/AndroidRuntime(29516): at android.widget.LinearLayout.onLayout(LinearLayout.java:1399) 06-29 10:29:02.777: E/AndroidRuntime(29516): at android.view.View.layout(View.java:11278) 06-29 10:29:02.777: E/AndroidRuntime(29516): at android.view.ViewGroup.layout(ViewGroup.java:4224) 06-29 10:29:02.777: E/AndroidRuntime(29516): at android.widget.FrameLayout.onLayout(FrameLayout.java:431) 06-29 10:29:02.777: E/AndroidRuntime(29516): at android.view.View.layout(View.java:11278) 06-29 10:29:02.777: E/AndroidRuntime(29516): at android.view.ViewGroup.layout(ViewGroup.java:4224) 06-29 10:29:02.777: E/AndroidRuntime(29516): at android.view.ViewRootImpl.performTraversals(ViewRootImpl.java:1489) 06-29 10:29:02.777: E/AndroidRuntime(29516): at android.view.ViewRootImpl.handleMessage(ViewRootImpl.java:2442) 06-29 10:29:02.777: E/AndroidRuntime(29516): at android.os.Handler.dispatchMessage(Handler.java:99) 06-29 10:29:02.777: E/AndroidRuntime(29516): at android.os.Looper.loop(Looper.java:137) 06-29 10:29:02.777: E/AndroidRuntime(29516): at android.app.ActivityThread.main(ActivityThread.java:4424) 06-29 10:29:02.777: E/AndroidRuntime(29516): at java.lang.reflect.Method.invokeNative(Native Method) 06-29 10:29:02.777: E/AndroidRuntime(29516): at java.lang.reflect.Method.invoke(Method.java:511) 06-29 10:29:02.777: E/AndroidRuntime(29516): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:784) 06-29 10:29:02.777: E/AndroidRuntime(29516): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:551) 06-29 10:29:02.777: E/AndroidRuntime(29516): at dalvik.system.NativeStart.main(Native Method) Code for iChecked (where the id is called) <ImageView android:id="@+id/checkBox" android:padding="2dip" android:layout_width="wrap_content" android:layout_height="wrap_content" android:background="@android:drawable/checkbox_on_background"/>

  • Accessing HttpRequest from Global.asax via a page

    - by Polymorphix
    I'm trying to get a property (ImpersonatePersonId) from a page in global.asax but get a HttpException saying 'Request is not available in this context'. I've been searching for some documentation on where in the pipeline the request is accessible, but as far as I can see all Microsoft can produce of documentation is one-liners like "PostRequestHandlerExecute: Occurs when the ASP.NET event handler finishes execution." which really doesn't give me much... I've tried placing the call in both Pre and PostRequestHandlerExceute but with the same result. I wonder if anyone with experience in this would be so kind as to tell me where the Request object is available. My code from global asax is below. ICanImpersonate page = HttpContext.Current.Handler as ICanImpersonate; ImpersonatedUser impersonatePerson = page != null ? page.ImpersonatePersonId : null; Response.Filter = new TagRewriter(Response, new TagProcessor(Context, impersonatePerson).Process); What I want to do is rewrite some HTML based on some request parameters.

  • How can I determine if a file I want to read from actually exists?

    - by Imray
    I'm learning Java, and I'm trying to write a program that can read from a .ser file, which I've already created with a writeTo method. I want to know a given file exists in the system before I tell the program to read from it. My code looks like this: public boolean readFromSerializedFile(String fileName){ FileInputStream fileInStream = null; ObjectInputStream objectInStream = null; try{ fileInStream = new FileInputStream(fileName); objectInStream = new ObjectInputStream(fileInStream); Is there a simple way I can determine if the file with the name of the parameter exists in the root directory (or wherever else specified)?

    Hey, my app parses numerous txt files in a directory that are almost all formatted identically, then inserts the values into columns of my sql db. However, there are a few files that the app has come across where a value is 'blank' instead of '0.0', so the application fails stating that it cannot convert that value to numeric. Is there a way I could change the following code to say what says AND also add 'IF value is blank, then import 0.0 instead? foreach (SqlParameter parameter in insertCommand.Parameters) { parameter.Value = null; } string[] values = line.Split(new[] { ',' }); for (int i = 0; i < values.Length - 1; i++) { // if (i = "" || i = null) continue; SqlParameter param = insertCommand.Parameters[i]; if (param.DbType == DbType.Decimal) { decimal value; param.Value = decimal.TryParse(values[i], out value) ? value : 0; } else { param.Value = values[i]; } }

  • Using Full-Text Search in SQL Server 2005 across multiple tables, columns

    - by crisgomez
    Hi, I have a problem, I created a full text search query which return a record(s), in which the paramater I have supplied match(es) in every fields(full-text indexed) of multiple tables. The problem is , when the user.id is equal to ceritification.AId it returns a records eventhough it was not satisfied with the parameter supplied. For this example I supplied a value "xandrick" which return an Id=184, but the problem is it returns two ids which is 184 and 154.What is the best way to return an ID(s) that satisfied of the supplied given value?

  • Is multi-level polymorphism possible in SQLAlchemy?

    - by Jace
    Is it possible to have multi-level polymorphism in SQLAlchemy? Here's an example: class Entity(Base): __tablename__ = 'entities' id = Column(Integer, primary_key=True) created_at = Column(DateTime, default=datetime.utcnow, nullable=False) entity_type = Column(Unicode(20), nullable=False) __mapper_args__ = {'polymorphic_on': entity_type} class File(Entity): __tablename__ = 'files' id = Column(None, ForeignKey('entities.id'), primary_key=True) filepath = Column(Unicode(255), nullable=False) file_type = Column(Unicode(20), nullable=False) __mapper_args__ = {'polymorphic_identity': u'file', 'polymorphic_on': file_type) class Image(File): __mapper_args__ = {'polymorphic_identity': u'image'} __tablename__ = 'images' id = Column(None, ForeignKey('files.id'), primary_key=True) width = Column(Integer) height = Column(Integer) When I call Base.metadata.create_all(), SQLAlchemy raises the following error: NotImplementedError: Can't generate DDL for the null type IntegrityError: (IntegrityError) entities.entity_type may not be NULL. This error goes away if I remove the Image model and the polymorphic_on key in File. What gives? (Edited: the exception raised was wrong.)

  • Using system Sound to play sounds

    - by Shoaibi
    Here is the code: -(void)stop { NSLog(@"Disposing Sounds"); AudioServicesDisposeSystemSoundID (soundID); //AudioServicesRemoveSystemSoundCompletion (soundID); } static void completionCallback (SystemSoundID mySSID, void* myself) { NSLog(@"completion Callback"); } - (void) playall: (id) sender { [self stop]; AudioServicesAddSystemSoundCompletion (soundID,NULL,NULL, completionCallback, (void*) self); OSStatus err = kAudioServicesNoError; NSString *aiffPath = [[NSBundle mainBundle] pathForResource:@"slide1" ofType:@"m4a"]; NSURL *aiffURL = [NSURL fileURLWithPath:aiffPath]; err = AudioServicesCreateSystemSoundID((CFURLRef) aiffURL, &soundID); AudioServicesPlaySystemSound (soundID); NSLog(@"Done Playing"); } Output: Disposing Sounds Done Playing In actual no sound gets play at all and completion call back isn't called as well. Any idea what could be wrong here? I want to stop any previous sound before playing current.

  • MySQL hangs if connection comes from outside the LAN

    - by Subito
    I have a MySQL Server operating just fine if I access him from his local LAN (192.168.100.0/24).

  • Record video file with 'thumbnail' image in Windows phone 8

    - by Deepak
    I'm trying to create a video capturing application store video file with 'thumbnail' image in Windows phone 8. I got some hint from the following link : How to get the thumbnail of a recorded video - windows phone 8?. But the result is quite annoying. I think there is some problem with the function. void captureSource_CaptureImageCompleted(object sender, CaptureImageCompletedEventArgs e) { using (IsolatedStorageFile isoStore = IsolatedStorageFile.GetUserStoreForApplication()) { WriteableBitmap wb = e.Result; string fileName = "CameraMovie.jpg"; if (isoStore.FileExists(fileName)) isoStore.DeleteFile(fileName); IsolatedStorageFileStream file = isoStore.CreateFile(fileName); Extensions.SaveJpeg(wb, file, wb.PixelWidth, wb.PixelHeight, 0, 85); file.Close(); captureSource.Stop(); fileSink.CaptureSource = null; fileSink.IsolatedStorageFileName = null; } } e.Result has some invalid data in it.while i bind it to an image control it shows some annoying image. Anyone please help me.

  • I have to select the checkbox two times to check/uncheck in jTable

    - by 117526709403775781607
    I have a jTable code i intend to use, but the problem with it is that when i click on the checkbox once it doesn't select/deselect it, instead i have to click twice. But if i select any other cell in the row except the one containing the checkbox the purpose is solved. HERE IS MY CODE : public class TableSelectionTest extends JFrame implements ListSelectionListener { private final int COLUMN_COUNT = 5; private TblModel model; public TableSelectionTest() { initialize(); setDefaultCloseOperation(EXIT_ON_CLOSE); pack(); } private void initialize() { List data = new ArrayList(); for (int i = 0; i < 10; i++) { Object record[] = new Object[COLUMN_COUNT]; record[0] = Boolean.FALSE; for (int j = 1; j < COLUMN_COUNT; j++) { record[j] = new Integer(j); } data.add(record); } model = new TblModel(data); JTable table = new JTable(model); table.getSelectionModel().setSelectionMode(ListSelectionModel.SINGLE_SELECTION); table.getSelectionModel().addListSelectionListener (this); JScrollPane scroll = new JScrollPane(table); getContentPane().add(scroll, BorderLayout.CENTER); } public static void main(String[] args) { TableSelectionTest f = new TableSelectionTest(); f.show(); } class TblModel extends AbstractTableModel { private List data; public TblModel(List data) { this.data = data; } public int getColumnCount() { return COLUMN_COUNT; } public int getRowCount() { return data == null ? 0 : data.size(); } public void setValueAt(Object value, int rowIndex, int columnIndex) { getRecord(rowIndex)[columnIndex] = value; super.fireTableCellUpdated(rowIndex, columnIndex); } public Object getValueAt(int rowIndex, int columnIndex) { return getRecord(rowIndex)[columnIndex]; } public boolean isCellEditable(int rowIndex, int columnIndex) { if(columnIndex == 0) return true; else return false; } public Class getColumnClass(int columnIndex) { if (data == null || data.size() == 0) { return Object.class; } Object o = getValueAt(0, columnIndex); return o == null ?

  • C# implicit conversions and == operator

    - by Arnis L.
    Some code for context: class a { } class b { public a a{get;set;} public static implicit operator a(b b) { return b.a; } } a a=null; b b=null; a = b; //compiler: cannot apply operator '==' to operands of type tralala... bool c = a == b; Is it possible to use == operator on different type instances, where one can implicitly convert to another? What did i miss? Edit: If types must be the same calling ==, then why int a=1; double b=1; bool c=a==b; works?

  • WCF Web/ServiceHost - Singletons and initialisation

    - by Kyle
    I have some Service class which is defined as InstanceContextMode.Single, and is well known in the hosting application. (The host creates an instance, and passes that to the WebServiceHost) Hosting app:WebServiceHost host = null; SomeService serviceInstance = new SomeService("text", "more text"); host = new WebServiceHost(serviceInstance, baseUri); Problem: When I go to use the variables initialised when the service is created (ie, when a call is made to the service), they are either null or empty... Am I wrong in assuming that as the instance being initialised in the hosting application is used for each request to the WebServiceHost? Any pointers here would be great.
