  • Windows 7 boot error

    - by jason
    I am running windows 7 professional, everything was working fine until I installed a software driver clearner suggested by nvidia customer service and I cleaned only nvidia graphic driver installation since then my windows does not work at all. I can access everything from startup repair, did lots of time repair but nothing happened. System restore does not work it says c: drive is not available, its 100% there and I can access every file from command prompt. Almost two days passed and I applied every solution discussed on several forums, now only thing left is either install fresh windows (Which i really don't want to do) or update windows (which windows does not let me to do, it says I have to update it from windows) My question is there any way to update (not fresh/custom installation) windows from command prompt? P.s: Safe mode, safe mode command nothing works except startup repair option. I ran sfc /scannow no problem found. I also removed all attached hardwares. Any help would be greatly appreciated.

  • Updating GeForce 9200 driver on Vista (64-bit) yields installer failed

    - by weka
    OK, so I have a Windows Vista... more specifically this: http://www.newegg.com/Product/Product.aspx?Item=N82E16883103182 a Acer Aspire AX3200-U3600A Desktop. I have DirectX 11 and I am trying to update my drivers... During the update of the latest one: GeForce 306.23 Driver my screen flashes a bit and goes black. This is standard when updating GRAPHIC DRIVERS. Then... my screen shifts 50 pixels or so to the left... OFFSCREEN. Not even Auto Image Adjust will fix the screen back... Then after that happens, I get this: Help, please? I just want to update my graphic drivers....

  • Windows 7 - all usb devices go to sleep im idle mode

    - by dvdx
    A strange thing happened after a few updates to the system: Intel rapid storage SSD firmware update Intel Ethernet adapter update GPU Intel update When the computer turns off the screen (after 5 min), an unknown time later, all the USB devices stop working. Sound card Mouse Keybord etc. I can't turn them back on, so I can't wake up the screen or do anything except turn the computer off and back on. I checked my power save profile and all is OK there. I changed in the Device Manager, the Allow USB to sleep in all the hubs. How can I fix this??

  • EXC_BAD_ACCESS error when box2d joint is destroyed

    - by colilo
    When I destroy the weldJoint in the update method (see below) I get an EXC_BAD_ACCESS error pointing to the line world->DestroyJoint(weldJoint); in the update method below: -(void) update: (ccTime) dt { int32 velocityIterations = 8; int32 positionIterations = 1; // Instruct the world to perform a single step of simulation. It is // generally best to keep the time step and iterations fixed. world->Step(dt, velocityIterations, positionIterations); // using the iterator pos over the set std::set<BodyPair *>::iterator pos; for(pos = bodiesForJoints.begin(); pos != bodiesForJoints.end(); ++pos) { b2WeldJointDef weldJointDef; BodyPair *bodyPair = *pos; b2Body *bodyA = bodyPair->bodyA; b2Body *bodyB = bodyPair->bodyB; weldJointDef.Initialize(bodyA, bodyB, bodyA->GetWorldCenter()); weldJointDef.collideConnected = false; weldJoint = (b2WeldJoint*) world->CreateJoint(&weldJointDef); // Free the structure we allocated earlier. free(bodyPair); // Remove the entry from the set. bodiesForJoints.erase(pos); } for(b2Body *b = world->GetBodyList(); b; b=b->GetNext()) { if (b->GetUserData() != NULL) { CCSprite *mainSprite = (CCSprite*)b->GetUserData(); if (mainSprite.tag == 1) { mainSprite.position = CGPointMake( b->GetPosition().x * PTM_RATIO, b->GetPosition().y * PTM_RATIO); CGPoint mainSpritePosition = mainSprite.position; if (mainSprite.isMoved) { world->DestroyJoint(weldJoint); } } } } } In the HelloWorldLayer.h I set the weldJoint with the assign property. Am I destroying the joint in the wrong way? I would really appreciate any help. Thanks

  • Pushing new mailbox limits for Exchange 2003 accounts

    - by Dobler
    There is this problem that I have every time I set up an account for a user on Exchange 2003. After I update the Mailbox limit to unlimited in the Exchange tab in the user preferences it does not seem to update right away. I remember reading somewhere that it takes several hours for the change to update in the database. I also remember typing in some terminal command that pushed the new updates immediately. What is that command, and why is it so difficult to find the answer to this problem on Google?

  • If and else condition not working properly in xna [closed]

    - by user1090751
    I am developing chess like game and i wanted to show error message if user try to place any player inside the box which is not empty. For example in certain place if there is empty then the object(2d object) is placed else it should show error message. However in my program it is showing message everytime i.e when i place object on empty place then also it is showing error message. Please see the below code: protected override void Update(GameTime gameTime) { // Allows the game to exit if (GamePad.GetState(PlayerIndex.One).Buttons.Back == ButtonState.Pressed) this.Exit(); // TODO: Add your update logic here for (int i = 0; i < 25; i++) { MouseState mouseState; mouseDiBack = false; mouseState = Mouse.GetState(); if (new Rectangle(mouseState.X, mouseState.Y, 1, 1).Intersects(rect_arr[i])) { background_color_arr[i] = Color.Red; } else { background_color_arr[i] = Color.White; } if (new Rectangle(mouseState.X, mouseState.Y, 1, 1).Intersects(rect_arr[i]) && (mouseState.LeftButton == ButtonState.Pressed)) { if (boxes[i] != "goat" && boxes[i] != "tiger") { place = i; if (turn == "goat") { boxes[i] = "goat"; turn = "tiger"; } else { boxes[i] = "tiger"; turn = "goat"; } } else { errMsg = "This " + i + " block is not empty to place " + turn + ". Please select empty block!!"; } } } base.Update(gameTime); }

  • Python/numpy tricky slicing problem

    - by daver
    Hi stack overflow, I have a problem with some numpy stuff. I need a numpy array to behave in an unusual manner by returning a slice as a view of the data I have sliced, not a copy. So heres an example of what I want to do: Say we have a simple array like this: a = array([1, 0, 0, 0]) I would like to update consecutive entries in the array (moving left to right) with the previous entry from the array, using syntax like this: a[1:] = a[0:3] This would get the following result: a = array([1, 1, 1, 1]) Or something like this: a[1:] = 2*a[:3] # a = [1,2,4,8] To illustrate further I want the following kind of behaviour: for i in range(len(a)): if i == 0 or i+1 == len(a): continue a[i+1] = a[i] Except I want the speed of numpy. The default behavior of numpy is to take a copy of the slice, so what I actually get is this: a = array([1, 1, 0, 0]) I already have this array as a subclass of the ndarray, so I can make further changes to it if need be, I just need the slice on the right hand side to be continually updated as it updates the slice on the left hand side. Am I dreaming or is this magic possible? Update: This is all because I am trying to use Gauss-Seidel iteration to solve a linear algebra problem, more or less. It is a special case involving harmonic functions, I was trying to avoid going into this because its really not necessary and likely to confuse things further, but here goes. The algorithm is this: while not converged: for i in range(len(u[:,0])): for j in range(len(u[0,:])): # skip over boundary entries, i,j == 0 or len(u) u[i,j] = 0.25*(u[i-1,j] + u[i+1,j] + u[i, j-1] + u[i,j+1]) Right? But you can do this two ways, Jacobi involves updating each element with its neighbours without considering updates you have already made until the while loop cycles, to do it in loops you would copy the array then update one array from the copied array. However Gauss-Seidel uses information you have already updated for each of the i-1 and j-1 entries, thus no need for a copy, the loop should essentially 'know' since the array has been re-evaluated after each single element update. That is to say, every time we call up an entry like u[i-1,j] or u[i,j-1] the information calculated in the previous loop will be there. I want to replace this slow and ugly nested loop situation with one nice clean line of code using numpy slicing: u[1:-1,1:-1] = 0.25(u[:-2,1:-1] + u[2:,1:-1] + u[1:-1,:-2] + u[1:-1,2:]) But the result is Jacobi iteration because when you take a slice: u[:,-2,1:-1] you copy the data, thus the slice is not aware of any updates made. Now numpy still loops right? Its not parallel its just a faster way to loop that looks like a parallel operation in python. I want to exploit this behaviour by sort of hacking numpy to return a pointer instead of a copy when I take a slice. Right? Then every time numpy loops, that slice will 'update' or really just replicate whatever happened in the update. To do this I need slices on both sides of the array to be pointers. Anyway if there is some really really clever person out there that awesome, but I've pretty much resigned myself to believing the only answer is to loop in C.

  • Persistence classes in Qt

    - by zarzych
    Hi, I'm porting a medium-sized CRUD application from .Net to Qt and I'm looking for a pattern for creating persistence classes. In .Net I usually created abstract persistence class with basic methods (insert, update, delete, select) for example: public class DAOBase<T> { public T GetByPrimaryKey(object primaryKey) {...} public void DeleteByPrimaryKey(object primaryKey) {...} public List<T> GetByField(string fieldName, object value) {...} public void Insert(T dto) {...} public void Update(T dto) {...} } Then, I subclassed it for specific tables/DTOs and added attributes for DB table layout: [DBTable("note", "note_id", NpgsqlTypes.NpgsqlDbType.Integer)] [DbField("note_id", NpgsqlTypes.NpgsqlDbType.Integer, "NoteId")] [DbField("client_id", NpgsqlTypes.NpgsqlDbType.Integer, "ClientId")] [DbField("title", NpgsqlTypes.NpgsqlDbType.Text, "Title", "")] [DbField("body", NpgsqlTypes.NpgsqlDbType.Text, "Body", "")] [DbField("date_added", NpgsqlTypes.NpgsqlDbType.Date, "DateAdded")] class NoteDAO : DAOBase<NoteDTO> { } Thanks to .Net reflection system I was able to achieve heavy code reuse and easy creation of new ORMs. The simplest way to do this kind of stuff in Qt seems to be using model classes from QtSql module. Unfortunately, in my case they provide too abstract an interface. I need at least transactions support and control over individual commits which QSqlTableModel doesn't provide. Could you give me some hints about solving this problem using Qt or point me to some reference materials? Update: Based on Harald's clues I've implemented a solution that is quite similar to the .Net classes above. Now I have two classes. UniversalDAO that inherits QObject and deals with QObject DTOs using metatype system: class UniversalDAO : public QObject { Q_OBJECT public: UniversalDAO(QSqlDatabase dataBase, QObject *parent = 0); virtual ~UniversalDAO(); void insert(const QObject &dto); void update(const QObject &dto); void remove(const QObject &dto); void getByPrimaryKey(QObject &dto, const QVariant &key); }; And a generic SpecializedDAO that casts data obtained from UniversalDAO to appropriate type: template<class DTO> class SpecializedDAO { public: SpecializedDAO(UniversalDAO *universalDao) virtual ~SpecializedDAO() {} DTO defaultDto() const { return DTO; } void insert(DTO dto) { dao->insert(dto); } void update(DTO dto) { dao->update(dto); } void remove(DTO dto) { dao->remove(dto); } DTO getByPrimaryKey(const QVariant &key); }; Using the above, I declare the concrete DAO class as following: class ClientDAO : public QObject, public SpecializedDAO<ClientDTO> { Q_OBJECT public: ClientDAO(UniversalDAO *dao, QObject *parent = 0) : QObject(parent), SpecializedDAO<ClientDTO>(dao) {} }; From within ClientDAO I have to set some database information for UniversalDAO. That's where my implementation gets ugly because I do it like this: QMap<QString, QString> fieldMapper; fieldMapper["client_id"] = "clientId"; fieldMapper["name"] = "firstName"; /* ...all column <-> field pairs in here... */ dao->setFieldMapper(fieldMapper); dao->setTable("client"); dao->setPrimaryKey("client_id"); I do it in constructor so it's not visible at a first glance for someone browsing through the header. In .Net version it was easy to spot and understand. Do you have some ideas how I could make it better?

  • How can I get SQL Server transactions to use record-level locks?

    - by Joe White
    We have an application that was originally written as a desktop app, lo these many years ago. It starts a transaction whenever you open an edit screen, and commits if you click OK, or rolls back if you click Cancel. This worked okay for a desktop app, but now we're trying to move to ADO.NET and SQL Server, and the long-running transactions are problematic. I found that we'll have a problem when multiple users are all trying to edit (different subsets of) the same table at the same time. In our old database, each user's transaction would acquire record-level locks to every record they modified during their transaction; since different users were editing different records, everyone gets their own locks and everything works. But in SQL Server, as soon as one user edits a record inside a transaction, SQL Server appears to get a lock on the entire table. When a second user tries to edit a different record in the same table, the second user's app simply locks up, because the SqlConnection blocks until the first user either commits or rolls back. I'm aware that long-running transactions are bad, and I know that the best solution would be to change these screens so that they no longer keep transactions open for a long time. But since that would mean some invasive and risky changes, I also want to research whether there's a way to get this code up and running as-is, just so I know what my options are. How can I get two different users' transactions in SQL Server to lock individual records instead of the entire table? Here's a quick-and-dirty console app that illustrates the issue. I've created a database called "test1", with one table called "Values" that just has ID (int) and Value (nvarchar) columns. If you run the app, it asks for an ID to modify, starts a transaction, modifies that record, and then leaves the transaction open until you press ENTER. I want to be able to start the program and tell it to update ID 1; let it get its transaction and modify the record; start a second copy of the program and tell it to update ID 2; have it able to update (and commit) while the first app's transaction is still open. Currently it freezes at step 4, until I go back to the first copy of the app and close it or press ENTER so it commits. The call to command.ExecuteNonQuery blocks until the first connection is closed. public static void Main() { Console.Write("ID to update: "); var id = int.Parse(Console.ReadLine()); Console.WriteLine("Starting transaction"); using (var scope = new TransactionScope()) using (var connection = new SqlConnection(@"Data Source=localhost\sqlexpress;Initial Catalog=test1;Integrated Security=True")) { connection.Open(); var command = connection.CreateCommand(); command.CommandText = "UPDATE [Values] SET Value = 'Value' WHERE ID = " + id; Console.WriteLine("Updating record"); command.ExecuteNonQuery(); Console.Write("Press ENTER to end transaction: "); Console.ReadLine(); scope.Complete(); } } Here are some things I've already tried, with no change in behavior: Changing the transaction isolation level to "read uncommitted" Specifying a "WITH (ROWLOCK)" on the UPDATE statement

  • Different setter behavior between DbContext and ObjectContext

    - by Paul
    (This is using EntityFramework 4.2 CTP) I haven't found any references to this on the web yet, although it's likely I'm using the wrong terminology while searching. There's also a very likely scenario where this is 100% expected behavior, just looking for confirmation and would rather not dig through the tt template (still new to this). Assuming I have a class with a boolean field called Active and I have one row that already has this value set to true. I have code that executes to set said field to True regardless of it's existing value. If I use DbContext to update the value to True no update is made. If I use ObjectContext to update the value an update is made regardless of the existing value. This is happening in the exact same EDMX, all I did was change the code generation template from DbContext to EntityObject. Update: Ok, found the confirmation I was looking for...consider this a dupe...next time I'll do MOAR SEARCHING! Entity Framework: Cancel a property change if no change in value ** Update 2: ** Problem: the default tt template wraps the "if (this != value)" in the setter with "if (iskey), so only primarykey fields receive this logic. Solution: it's not the most graceful thing, but I removed this check...we'll see how it pans out in real usage. I included the entire tt template, my changes are denoted with "**"... //////// //////// Write SimpleType Properties. //////// private void WriteSimpleTypeProperty(EdmProperty simpleProperty, CodeGenerationTools code) { MetadataTools ef = new MetadataTools(this); #> /// <summary> /// <#=SummaryComment(simpleProperty)#> /// </summary><#=LongDescriptionCommentElement(simpleProperty, 1)#> [EdmScalarPropertyAttribute(EntityKeyProperty= <#=code.CreateLiteral(ef.IsKey(simpleProperty))#>, IsNullable=<#=code.CreateLiteral(ef.IsNullable(simpleProperty))#>)] [DataMemberAttribute()] <#=code.SpaceAfter(NewModifier(simpleProperty))#><#=Accessibility.ForProperty(simpleProperty)#> <#=MultiSchemaEscape(simpleProperty.TypeUsage, code)#> <#=code.Escape(simpleProperty)#> { <#=code.SpaceAfter(Accessibility.ForGetter(simpleProperty))#>get { <#+ if (ef.ClrType(simpleProperty.TypeUsage) == typeof(byte[])) { #> return StructuralObject.GetValidValue(<#=code.FieldName(simpleProperty)#>); <#+ } else { #> return <#=code.FieldName(simpleProperty)#>; <#+ } #> } <#=code.SpaceAfter(Accessibility.ForSetter((simpleProperty)))#>set { <#+ **//if (ef.IsKey(simpleProperty)) **//{ if (ef.ClrType(simpleProperty.TypeUsage) == typeof(byte[])) { #> if (!StructuralObject.BinaryEquals(<#=code.FieldName(simpleProperty)#>, value)) <#+ } else { #> if (<#=code.FieldName(simpleProperty)#> != value) <#+ } #> { <#+ PushIndent(CodeRegion.GetIndent(1)); **//} #> <#=ChangingMethodName(simpleProperty)#>(value); ReportPropertyChanging("<#=simpleProperty.Name#>"); <#=code.FieldName(simpleProperty)#> = <#=CastToEnumType(simpleProperty.TypeUsage, code)#>StructuralObject.SetValidValue(<#=CastToUnderlyingType(simpleProperty.TypeUsage, code)#>value<#=OptionalNullableParameterForSetValidValue(simpleProperty, code)#>, "<#=simpleProperty.Name#>"); ReportPropertyChanged("<#=simpleProperty.Name#>"); <#=ChangedMethodName(simpleProperty)#>(); <#+ //if (ef.IsKey(simpleProperty)) //{ PopIndent(); #> } <#+ //} #> } }

  • With NHibernate, how can I add a child object when updating a parent object?

    - by BMZ
    I have a simple Parent/Child relationship between a Person object and an Address object. The Person object exists in the DB. After doing a Get on the Person, I add a new Address object to the Address sub-object list of the parent, and do some other updates to the Person object. Finally, I do an Update on the Person object. With a SQL trace window, I can see the update to the Person object to the Person table and the Insert of the Address record to the Address table. The issue is that, after the update is performed, the AddressId (primary key on the Address object) is still set to 0, which is what it defaults to when you first initialize the Address object. I have verified that when I do an Add, this value is set correctly. Is this a known issue when trying to add sub-objects as part of an NHibernate UPDATE? Sample code and mapping files are below Thanks <hibernate-mapping xmlns="urn:nhibernate-mapping-2.2"> <class name="BusinessEntities.Wellness.Person,BusinessEntities.Wellness" table="Person" lazy="true" dynamic-insert="true" dynamic-update="false"> <id name="Personid" column="PersonID" type="int"> <generator class="native" /> </id> <version type="binary" generated="always" name="RecordVersion" column="`RecordVersion`"/> <property type="int" not-null="true" name="Customerid" column="`CustomerID`" /> <property type="AnsiString" not-null="true" length="9" name="Ssn" column="`SSN`" /> <property type="AnsiString" not-null="true" length="30" name="FirstName" column="`FirstName`" /> <property type="AnsiString" not-null="true" length="35" name="LastName" column="`LastName`" /> <property type="AnsiString" length="1" name="MiddleInitial" column="`MiddleInitial`" /> <property type="DateTime" name="DateOfBirth" column="`DateOfBirth`" /> <bag name="PersonAddresses" inverse="true" lazy="true" cascade="all"> <key column="PersonID" /> <one-to-many class="BusinessEntities.Wellness.PersonAddress,BusinessEntities.Wellness" / </bag> </class> </hibernate-mapping> <hibernate-mapping xmlns="urn:nhibernate-mapping-2.2"> <class name="BusinessEntities.Wellness.PersonAddress,BusinessEntities.Wellness" table="PersonAddress" lazy="true" dynamic-insert="true" dynamic-update="false"> <id name="PersonAddressId" column="PersonAddressID" type="int"> <generator class="native" /> </id> <version type="binary" generated="always" name="RecordVersion" column="`RecordVersion`" /> <property type="AnsiString" not-null="true" length="1" name="AddressTypeid" column="`AddressTypeID`" /> <property type="AnsiString" not-null="true" length="60" name="AddressLine1" column="`AddressLine1`" /> <property type="AnsiString" length="60" name="AddressLine2" column="`AddressLine2`" /> <property type="AnsiString" length="60" name="City" column="`City`" /> <property type="AnsiString" length="2" name="UsStateId" column="`USStateID`" /> <property type="AnsiString" length="5" name="UsPostalCodeId" column="`USPostalCodeID`" /> <many-to-one name="Person" cascade="none" column="PersonID" /> </class> </hibernate-mapping> Person newPerson = new Person(); newPerson.PersonName = "John Doe"; newPerson.SSN = "111111111"; newPerson.CreatedBy = "RJC"; newPerson.CreatedDate = DateTime.Today; personDao.AddPerson(newPerson); Person updatePerson = personDao.GetPerson(newPerson.PersonId); updatePerson.PersonAddresses = new List<PersonAddress>(); PersonAddress addr = new PersonAddress(); addr.AddressLine1 = "1 Main St"; addr.City = "Boston"; addr.State = "MA"; addr.Zip = "12345"; updatePerson.PersonAddresses.Add(addr); personDao.UpdatePerson(updatePerson); int addressID = updatePerson.PersonAddresses[0].AddressId;

  • [Qt/C++] Need help in optimizing a drawing code ...

    - by Ahmad
    Hello all ... I needed some help in trying to optimize this code portion ... Basically here's the thing .. I'm making this 'calligraphy pen' which gives the calligraphy effect by simply drawing a lot of adjacent slanted lines ... The problem is this: When I update the draw region using update() after every single draw of a slanted line, the output is correct, in the sense that updates are done in a timely manner, so that everything 'drawn' using the pen is immediately 'seen' the drawing.. however, because a lot (100s of them) of updates are done, the program slows down a little when run on the N900 ... When I try to do a little optimization by running update after drawing all the slanted lines (so that all lines are updated onto the drawing board through a single update() ), the output is ... odd .... That is, immediately after drawing the lines, they lines seem broken (they have vacant patches where the drawing should have happened as well) ... however, if I trigger a redrawing of the form window (say, by changing the size of the form), the broken patches are immediately fixed !! When I run this program on my N900, it gets the initial broken output and stays like that, since I don't know how to enforce a redraw in this case ... Here is the first 'optimized' code and output (partially correct/incorrect) void Canvas::drawLineTo(const QPoint &endPoint) { QPainter painter(&image); painter.setPen(QPen(Qt::black,1,Qt::SolidLine,Qt::RoundCap,Qt::RoundJoin)); int fx=0,fy=0,k=0; qPoints.clear(); connectingPointsCalculator2(qPoints,lastPoint.x(),lastPoint.y(),endPoint.x(),endPoint.y()); int i=0; int x,y; for(i=0;i<qPoints.size();i++) { x=qPoints.at(i).x(); y=qPoints.at(i).y(); painter.setPen(Qt::black); painter.drawLine(x-5,y-5,x+5,y+5); **// Drawing slanted lines** } **//Updating only once after many draws:** update (QRect(QPoint(lastPoint.x()-5,lastPoint.y()-5), QPoint(endPoint.x()+5,endPoint.y()+5)).normalized()); modified = true; lastPoint = endPoint; } Image right after scribbling on screen: http://img823.imageshack.us/img823/8755/59943912.png After re-adjusting the window size, all the broken links above are fixed like they should be .. Here is the second un-optimized code (its output is correct right after drawing, just like in the second picture above): void Canvas::drawLineTo(const QPoint &endPoint) { QPainter painter(&image); painter.setPen(QPen(Qt::black,1,Qt::SolidLine,Qt::RoundCap,Qt::RoundJoin)); int fx=0,fy=0,k=0; qPoints.clear(); connectingPointsCalculator2(qPoints,lastPoint.x(),lastPoint.y(),endPoint.x(),endPoint.y()); int i=0; int x,y; for(i=0;i<qPoints.size();i++) { x=qPoints.at(i).x(); y=qPoints.at(i).y(); painter.setPen(Qt::black); painter.drawLine(x-5,y-5,x+5,y+5); **// Drawing slanted lines** **//Updating repeatedly during the for loop:** update(QRect(QPoint(x-5,y-5), QPoint(x+5,y+5)).normalized());//.adjusted(-rad,-rad,rad,rad)); } modified = true; int rad = (myPenWidth / 2) + 2; lastPoint = endPoint; } Can anyone see what the issue might be ?

  • Primefaces tabview: set the active index on tab change

    - by Virgi
    I've got a tab view that contains two tab. When I switch from tab 1 to tab 2, I'm calling some code that executes a validation and updates some values. Depending on the result of this validation, I would like to stay on tab 1, or go to tab 2, and refresh the tabs' content. My tabview: <h:form id="form"> <p:tabView id="tabview" activeIndex="#{ctrl.idx}" dynamic="true" cache="false"> <p:ajax event="tabChange" listener="#{ctrl.doStuff}" update=":form:tabview"/> <p:tab title="Tab 1" id="t1"> <h:panelGrid columns="1" cellpadding="10"> <h:outputText value="#{ctrl.s1}"/> </h:panelGrid> </p:tab> <p:tab title="Tab 2" id="t2"> <h:panelGrid columns="1" cellpadding="10"> <h:outputText value="#{ctrl.s2}"/> </h:panelGrid> </p:tab> </p:tabView> </h:form> My test code that simly changes the values: public void doStuff() { s1 = String.valueOf(Math.random()); s2 = String.valueOf(Math.random()); } I thought that changing the active tab index in my method would be enough, like that: public void doStuff() { // ... idx = 0; } On tabChange event, the method is called but the tabview components goes to the clicked tab, ignoring the idx new value. I thought adding an update attribute to p:ajax would render the whole tabview but only the tabs and/or the tabs' content is re rendered. And weirdest of all, if I change update=":form:tabview" to update=":form" or update="@form", I only receive the tab's content in the ajax response - the component disappears from the page! My bean is viewscoped, I'm using Primefaces 3.5, JSF 2.1 and Tomcat 7. Any idea? Thanks.

  • ASP.NET MVC 2 JQuery POST not displaying the model state errors

    - by Oshan
    Hello, I have been using asp.net mvc for a bit (but I'm still a beginer). I want to have the ability to update two views as a result of a jquery postback. Basically I have a list and a details view. The details view is presented using a jquery popup (using jquery-UI popup). I only want to update the list if the details save is successful (i.e. there are no validation errors on the details view). However, if there are any validation errros in the details view, I want to update the details view so that the user sees the validation errors. so I thought in my controller, I return a JsonResult instead of a View. [HttpPost] public ActionResult SavePersonInfo(Person p) { if(ModelState.Valid) { return View("PersonList"); } return Json({Error = true, View = PartialView("PersonDetails", p)}); } As you can see if there are no errors I return the person list view, but if there are any validation errors, I have return the details view. The reason that I'm returning a JsonResult is I need to tell my view there is an error so that the view (jquery) knows which section to update (as in whether to update the person list 'div' or the popup dialog 'div'). So, in my view, the jquery is as follows (please assume that there is a form for entering in the person details and "SubmitPersonForm();" function is called upon clicking on the "Save" button): <script type="text/javascript> $('#btnSave').click(function (event) { onBegin(); $.ajax( { type: "POST", url: "/Person/Save", data: $('form').serialize(), success: function (result) { if(result.Error) { $('#dvDetails').html($(result).View)); } else { $('#dvPersonList').html($result); } } }); }); </script> So the problem that I have now, is that when there is a validation error, I do see the correct, 'div' being updated, but I lose the asp.net mvc validation messages. I do not see any validation errors in red, as if ASP.NET MVC is completely ignored them. However, my ModelState does have those errros, just not displayed in the details view. I do have valication summary and Html.ValidationFor(m = ...) statements put in my details view. Could someone tell me why I'm not seeing the validation errors? although I'm using a JSonResult, I do use the right property which is a valid view when I render the 'dvDetails'. Am I doing something that I'm not suppose to in asp.net mvc? Btw I'm using asp.net mvc2 RC with Visual Studio 2010 RC. Thank you.

  • How to show server errors in Rails 2.3.5 with JSON and jQuery

    - by Fortuity
    I've got in-place editing on a page in my app (using Rails 2.3.5 and jQuery). I want to know how to display an error on the page when the update fails. I'm using ajax (an XMLHttpRequest) to save an update to a Comment object. The controller has an update method like this: def update @comment = Comment.find(params[:id]) respond_to do |format| # if @comment.update_attributes!(params[:comment]) if false #deliberately forcing a fail here to see what happens format.json { render :nothing => true } else format.json { render :json => @comment.errors, :status => :unprocessable_entity } end end end In Firebug, I can see the server returns a "422" (an appropriate validation error status code). But it's a response to an XMLHttpRequest so there is no redirect to an error page. I think I actually want to do this: format.json { render :json => @comment.errors} or maybe this: format.json {render :json => { :status => :error, :message => "Could not be saved" }.to_json, :status => 400 } and trigger some Javascript function that iterates through (and displays) any errors. I'm using a rails plugin http://github.com/janv/rest_in_place/ to implement the in-place editing. It doesn't appear to have any callback function to handle a failure. What are my options? Can I write some Javascript to respond to a failure condition without hacking the plugin? Do I have to hack the rest_in_place plugin to handle a failure condition? Is there a better plugin (for Rails or jQuery) that handles in-place editing, including failure conditions? UPDATE This post from Peter Bui (http://paydrotalks.com/posts/45-standard-json-response-for-rails-and-jquery) was helpful in showing how to handle an error message from the server using XMLHttpRequest.status. I looked at his implementation of a blog using ajax (http://github.com/paydro/talks). I'm surprised at the complexity required to handle a simple error condition. Usually Rails has all the goodness baked in but it seems server errors with JSON are out of scope. Can that be? I also looked at grimen's validatious-on-rails (http://github.com/grimen/validatious-on-rails/) which accommodates models validations when ajax XMLHttpRequest is used. It's not clear to me how I'd use it to handle the general case of a "save" failing when validations succeed. P.S. Please vote me up... so I can use more than one HTML link when I ask my question :-)

  • Spring transaction demarcation causes new Hibernate session despite use of OSIV

    - by Kelly Ellis
    I'm using Hibernate with OpenSessionInViewInterceptor so that a single Hibernate session will be used for the entire HTTP request (or so I wish). The problem is that Spring-configured transaction boundaries are causing a new session to be created, so I'm running into the following problem (pseudocode): Start in method marked @Transactional(propagation = Propagation.SUPPORTS, readOnly = false) Hibernate session #1 starts Call DAO method to update object foo; foo gets loaded into session cache for session #1 Call another method to update foo.bar, this one is marked @Transactional(propagation = Propagation.REQUIRED, readOnly = false) Transaction demarcation causes suspension of current transaction synchronization, which temporarily unbinds the current Hibernate session Hibernate session #2 starts since there's no currently-existing session Update field bar on foo (loading foo into session cache #2); persist to DB Transaction completes and method returns, session #1 resumes Call yet another method to update another field on foo Load foo from session cache #1, with old, incorrect value of bar Update field foo.baz, persist foo to DB foo.bar's old value overwrites the change we made in the previous step Configuration looks like: <bean name="openSessionInViewInterceptor" class="org.springframework.orm.hibernate3.support.OpenSessionInViewInterceptor" autowire="byName"> <property name="flushModeName"> <value>FLUSH_AUTO</value> </property> </bean> <bean id="txManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <property name="dataSource" ref="myDataSource" /> </bean> <bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"> <property name="useTransactionAwareDataSource" value="true" /> <property name="mappingLocations"> <list> <value>/WEB-INF/xml/hibernate/content.hbm.xml</value> </list> </property> <property name="lobHandler"> <ref local="oracleLobHandler" /> </property> <!--property name="entityInterceptor" ref="auditLogInterceptor" /--> <property name="hibernateProperties" ref="HibernateProperties" /> <property name="dataSource" ref="myDataSource" /> </bean> I've done some debugging and figured out exactly where this is happening, here is the stack trace: Daemon Thread [http-8080-1] (Suspended (entry into method doUnbindResource in TransactionSynchronizationManager)) TransactionSynchronizationManager.doUnbindResource(Object) line: 222 TransactionSynchronizationManager.unbindResource(Object) line: 200 SpringSessionSynchronization.suspend() line: 115 DataSourceTransactionManager(AbstractPlatformTransactionManager).doSuspendSynchronization() line: 620 DataSourceTransactionManager(AbstractPlatformTransactionManager).suspend(Object) line: 549 DataSourceTransactionManager(AbstractPlatformTransactionManager).getTransaction(TransactionDefinition) line: 372 TransactionInterceptor(TransactionAspectSupport).createTransactionIfNecessary(TransactionAttribute, String) line: 263 TransactionInterceptor.invoke(MethodInvocation) line: 101 ReflectiveMethodInvocation.proceed() line: 171 JdkDynamicAopProxy.invoke(Object, Method, Object[]) line: 204 $Proxy14.changeVisibility(Long, ContentStatusVO, ContentAuditData) line: not available I can't figure out why transaction boundaries (even "nested" ones - though here we're just moving from SUPPORTS to REQUIRED) would cause the Hibernate session to be suspended, even though OpenSessionInViewInterceptor is in use. When the session is unbound, I see the following in my logs: [2010-02-16 18:20:59,150] DEBUG org.springframework.transaction.support.TransactionSynchronizationManager Removed value [org.springframework.orm.hibernate3.SessionHolder@7def534e] for key [org.hibernate.impl.SessionFactoryImpl@693f23a2] from thread [http-8080-1]

When clicking on links in a main nav, the url is updated properly, but when links are loaded dynamically with ajax, the url address function breaks. I have made 'click' events live, allowing for content to be loaded via dynamically loaded links, but I can't seem to make the address event listener live, but this seems to be the only way to make this work. Is my syntax wrong if I change this : $.address.change(function(event) { to this: $.address.live('change', function(event) { or does the live method not work with this plugin?

  • DataRelation Insert and ForeignKey

    - by Steve
    Guys, I have a winforms application with two DataGridViews displaying a master-detail relationship from my Person and Address tables. Person table has a PersonID field that is auto-incrementing primary key. Address has a PersonID field that is the FK. I fill my DataTables with DataAdapter and set Person.PersonID column's AutoIncrement=true and AutoIncrementStep=-1. I can insert records in the Person DataTable from the DataGridView. The PersonID column displays unique negative values for PersonID. I update the database by calling DataAdapter.Update(PersonTable) and the negative PersonIDs are converted to positive unique values automatically by SQL Server. Here's the rub. The Address DataGridView show the address table which has a DataRelation to Person by PersonID. Inserted Person records have the temporary negative PersonID. I can now insert records into Address via DataGridView and Address.PersonID is set to the negative value from the DataRelation mapping. I call Adapter.Update(AddressTable) and the negative PersonIDs go into the Address table breaking the relationship. How do you guys handle primary/foreign keys using DataTables and master-detail DataGridViews? Thanks! Steve EDIT: After more googling, I found that SqlDataAdapter.RowUpdated event gives me what I need. I create a new command to query the last id inserted by using @@IDENTITY. It works pretty well. The DataRelation updates the Address.PersonID field for me so it's required to Update the Person table first then update the Address table. All the new records insert properly with correct ids in place! Adapter = new SqlDataAdapter(cmd); Adapter.RowUpdated += (s, e) => { if (e.StatementType != StatementType.Insert) return; //set the id for the inserted record SqlCommand c = e.Command.Connection.CreateCommand(); c.CommandText = "select @@IDENTITY id"; e.Row[0] = Convert.ToInt32( c.ExecuteScalar() ); }; Adapter.Fill(this); SqlCommandBuilder sb = new SqlCommandBuilder(Adapter); sb.GetDeleteCommand(); sb.GetUpdateCommand(); sb.GetInsertCommand(); this.Columns[0].AutoIncrement = true; this.Columns[0].AutoIncrementSeed = -1; this.Columns[0].AutoIncrementStep = -1;

    I've got a very weird bug which I've yet to find a solution. UPDATE see solution below What I am trying to do is convert a full size picture into a 160x120 thumbnail. It works great with jpg and jpeg files of any size, but not with png. ImageMagick command: /opt/local/bin/convert '/WEBSERVER/images/img_0003-192-10.png' -thumbnail x320 -resize '320x<' -resize 50% -gravity center -crop 160x120+0+0 +repage -quality 91 '/WEBSERVER/thumbs/small_img_0003-192-10.png' PHP function (shortened) ... $cmd = "/opt/local/bin/convert '/WEBSERVER/images/img_0003-192-10.png' -thumbnail x320 -resize '320x<' -resize 50% -gravity center -crop 160x120+0+0 +repage -quality 91 '/WEBSERVER/thumbs/small_img_0003-192-10.png'"; exec($cmd, $output, $retval); $errors += $retval; if ($errors > 0) { die(print_r($output)); } When this function runs $retval equal 1 which means the convert command failed (thumbnail isn't created). This is where it gets interesting, if I run the exact same command in my shell, it works. wedbook:~ wedix$ /opt/local/bin/convert '/WEBSERVER/images/img_0003-192-10.png' -thumbnail x320 -resize '320x<' -resize 50% -gravity center -crop 160x120+0+0 +repage -quality 91 '/WEBSERVER/thumbs/small_img_0003-192-10.png' wedbook:~ wedix$ I've tried using different PHP function such as system, passthru but it didn't work.

  • when to use the abstract factory pattern?

    Hi: I want to know when we need to use the abstract factory pattern. Here is an example,I want to know if it is necessary.

    - by PlasmaFlux
    Hello Overflowers! Here's what's going on: I'm building an app (using PHP, jQuery, etc), part of which lets users edit various bits of a web page (Header, Footer, Main Content, Sidebar) using CKEditor. It's set up so that each editable bit has an "Edit Content" button in the upper right that, on click, launches an instance of CKEditor inside a jQuery-UI Dialog box. After the user is done editing, they can click an 'Update Changes' button that passes the edited content back off to the main page and closes the Dialog/CKeditor. It's all working magnificently, save for one thing. If someone inserts any JavaScript code, wrapped in 'script' tags, using either the Insert HTML Plugin for CKEditor or by going to 'Source' in CKEditor and placing the code in the source, everything seems okay until they click the 'Update Changes' button. The JavaScript appears to be inserting properly, but when 'Update Changes' is clicked, instead of the Dialog closing and passing the script back into the div where it belongs, what I get instead is an all-white screen with just the output of the JavaScript. For example, a simple 'Hello World' script results in a white screen with the string 'Hello World' in the upper left corner; for more intricate scripts, like an API call to, say Aweber, that generates a newsletter signup form, I get an all-white screen with the resulting form from the Aweber API call perfectly rendered in the middle of the screen. One of the most confusing parts is that, on these pages, if I click 'View Source', I get absolutely nothing. Blank emptiness. Here's all my code that handles the launching of the CKEditor instance inside the jQuery-UI Dialog, and the passing of the edited data back into its associated div on click of the 'Update Changes' button: $(function() { $('.foobar_edit_button') .button() .click(function() { var beingEdited = $(this).nextAll('.foobar_editable').attr('id'); var content = $(this).nextAll('.foobar_editable').html(); $('#foobar_editor').html(content); $('#foobar_editor').dialog( { open:function() { $(this).ckeditor(function() { CKFinder.SetupCKEditor( this, '<?php echo '/foobar/lib/editor/ckfinder/'; ?>' ); }); }, close:function() { $(this).ckeditorGet().destroy(); }, autoOpen: false, width: 840, modal: true, buttons: { 'Update Changes': function() { // TODO: submit changes to server via ajax once its completed: for ( instance in CKEDITOR.instances ) CKEDITOR.instances[instance].updateElement(); var edited_content = $('#foobar_editor').html(); $('#' + beingEdited).html(edited_content); $(this).dialog('close'); } } }); $('#foobar_editor').dialog('open'); }); }); I'm all sorts of confused. If anyone can point me in the right direction, it will be greatly appreciated. Thanks!
