• NHibernate's automatic (dirty checking) update behaviour - turning it off

  - by Andrew Bullock

  I've just discovered that if I get an object from an NHibernate session and change a property on object, NHibernate will automatically update the object on commit without me calling Session.Update(myObj)! I can see how this could be helpful, but as default behaviour it seems crazy! How can I stop this happening? Is this default NHib behaviour or something coming from Fluent NHibs AutoPersistenceModel? If there's no way to stop this, what do I do? Unless I'm missing the point this behaviour seems to create a right mess, violating my UoW. Im using NHibernate 2.0.1.4 and a Fluent NHib build from 18/3/2009 Edit, is this guy right with his answer? Edit: I've also read that overriding an Event Listener could be a solution to this. However, IDirtyCheckEventListener.OnDirtyCheck isn't called in this situation. Does anyone know which listener I need to override? Thanks Andrew

• How to update the InnoSetup Wizard GUI status text from PascalScript code

  - by mkva

  Hi I execute a lot of custom actions in my InnoSetup script in the CurStepChanged(ssPostInstall) PascalScripting event handler. As these actions take some time to finish, I'd like to update the InnoSetup Wizard GUI status text and tell the user what is going on behind the scenes. Something similar that is possible in the [Run] section using the "StatusMsg" parameter. I know that I could use the TOutputProgressWizardPage/CreateOutputProgressPage(), and I did in a previous project, but it's a bit too much overkill to my liking... Is there a simpler possibility to update the InnoSetup Wizard GUI status text from PascalScripting code with the same effect as the StatusMsg parameter?

• only update certain model attributes using Backbone.js

  - by Drew Dara-Abrams

  With Backbone, I'm trying to update and save to the server just one attribute: currentUser.save({hide_explorer_tutorial: 'true'}); but I don't want to send all the other attributes. Some of them are actually the output of methods on the server-side and so they are not actually true attributes with setter functions. Currently I'm using unset(attribute_name) to remove all the attributes that I don't want to update on the server. Problem is those attributes are then no longer available for local use. Suggestions on how to only save certain attributes to the server?

• MessageBox if Recordset Update is Successful

  - by Paolo Bernasconi

  In Access 2007, I have a form to add a new contact to a table: RecSet.AddNew RecSet![Code_Personal] = Me.txtCodePersonal.Value RecSet![FName] = Me.TxtFName.Value RecSet![LName] = Me.txtLName.Value RecSet![Tel Natel] = Me.txtNatTel.Value RecSet![Tel Home] = Me.txtHomeTel.Value RecSet![Email] = Me.txtEmail.Value RecSet.Update This has worked so far, and the contact has successfully been aded. But I'm having two problems: I want to display a messagebox to tell the user the contact was successfully added If the contact was not successfully added because A contact with this name already exists A different issue Then display a message box "Contact already exists" or "error occured" respectively. My idea of doing this is: If recSet.Update = true Then MsgBox "Paolo Bernasconi was successfully added" Else if RecSet![FName] & RecSet![LName] 'already exist in table MsgBox "Contact already exists" Else MsgBox "An unknown error occured" I know this code is wrong, and obviously doesn't work, but it's just to give you an idea of what I'm trying to achieve. Thanks for all your help in advance.

• Manually updating FF Add-ons

  - by cpp_fanatic

  My application installs my Firefox add-on (by copying an my.xpi to [FF_inst_dir]\extensions). This application interact with my FF add-on. This application periodically has updates (.xpi with new version). When my application is updating it does next: Remove folder and content [FF_inst_dir]\extensions\MyExtension Copy new my.xpi to [FF_inst_dir]\extensions However, when I restart FF I see: FF ask me about install add-on. I agree. FF remove my.xpi (it's ok) FF remove folder and content [FF_inst_dir]\extensions\MyExtension I think that FF try to remove old plugin. Thus, I havn't installed plugin. How it can be installed correct?

• SOAP web service evolution

  - by Thilo

  Are there any guidelines/tutorials as to how to handle the evolution of a SOAP web service? I can see that changing existing methods or types would probably not work, but can I just add new methods, complex types, enumeration values without breaking existing clients?

• PLS-00103: Encountered the symbol "end-of-file" in simple update block

  - by rageingnonsense

  Hello, The following Oracle statement: DECLARE ID NUMBER; BEGIN UPDATE myusername.terrainMap SET playerID = :playerID,tileLayout = :tileLayout WHERE ID = :ID END; Gives me the following error: ORA-06550: line 6, column 15: PL/SQL: ORA-00933: SQL command not properly ended ORA-06550: line 3, column 19: PL/SQL: SQL Statement ignored ORA-06550: line 6, column 18: PLS-00103: Encountered the symbol "end-of-file" when expecting one of the following: ( begin case declare end exception exit for goto if loop mod null pragma raise return select update while with <an identifier> <a double-quoted> I am pretty much at a loss. This appears to be a rather simple statement. If it helps any, I had a similar statement that performed an INSERT which used to work, but today has been giving me the same message.

• MemoryStream, XmlTextWriter and Warning 4 CA2202 : Microsoft.Usage

  - by rasx

  The Run Code Analysis command in Visual Studio 2010 Ultimate returns a warning when seeing a certain pattern with MemoryStream and XmlTextWriter. This is the warning: Warning 7 CA2202 : Microsoft.Usage : Object 'ms' can be disposed more than once in method 'KinteWritePages.GetXPathDocument(DbConnection)'. To avoid generating a System.ObjectDisposedException you should not call Dispose more than one time on an object.: Lines: 421 C:\Visual Studio 2010\Projects\Songhay.DataAccess.KinteWritePages\KinteWritePages.cs 421 Songhay.DataAccess.KinteWritePages This is the form: static XPathDocument GetXPathDocument(DbConnection connection) { XPathDocument xpDoc = null; var ms = new MemoryStream(); try { using(XmlTextWriter writer = new XmlTextWriter(ms, Encoding.UTF8)) { using(DbDataReader reader = CommonReader.GetReader(connection, Resources.KinteRssSql)) { writer.WriteStartDocument(); writer.WriteStartElement("data"); do { while(reader.Read()) { writer.WriteStartElement("item"); for(int i = 0; i < reader.FieldCount; i++) { writer.WriteRaw(String.Format("<{0}>{1}</{0}>", reader.GetName(i), reader[i].ToString())); } writer.WriteFullEndElement(); } } while(reader.NextResult()); writer.WriteFullEndElement(); writer.WriteEndDocument(); writer.Flush(); ms.Position = 0; xpDoc = new XPathDocument(ms); } } } finally { ms.Dispose(); } return xpDoc; } The same kind of warning is produced for this form: XPathDocument xpDoc = null; using(var ms = new MemoryStream()) { using(XmlTextWriter writer = new XmlTextWriter(ms, Encoding.UTF8)) { using(DbDataReader reader = CommonReader.GetReader(connection, Resources.KinteRssSql)) { //... } } } return xpDoc; By the way, the following form produces another warning: XPathDocument xpDoc = null; var ms = new MemoryStream(); using(XmlTextWriter writer = new XmlTextWriter(ms, Encoding.UTF8)) { using(DbDataReader reader = CommonReader.GetReader(connection, Resources.KinteRssSql)) { //... } } return xpDoc; The above produces the warning: Warning 7 CA2000 : Microsoft.Reliability : In method 'KinteWritePages.GetXPathDocument(DbConnection)', object 'ms' is not disposed along all exception paths. Call System.IDisposable.Dispose on object 'ms' before all references to it are out of scope. C:\Visual Studio 2010\Projects\Songhay.DataAccess.KinteWritePages\KinteWritePages.cs 383 Songhay.DataAccess.KinteWritePages In addition to the following, what are my options?: Supress warning CA2202. Supress warning CA2000 and hope that Microsoft is disposing of MemoryStream (because Reflector is not showing me the source code). Rewrite my legacy code to recognize the wonderful XDocument and LINQ to XML.

• Using EnterCriticalSection in Thread to update VCL label

  - by user257188

  I'm new to threads. I'm using a 3rd party library that uses threads which at times call a procedure I've provided. How do I update update a TLabel.Caption from my procedure when its called by the thread? If I've called InitializeCriticalSection elsewhere, is it as simple as EnterCriticalSection(CritSect); GlobalVariable := 'New TLabel.Caption'; LeaveCriticalSection(CritSect); And then in my main thread: EnterCriticalSection(CritSect); Label1.Caption:= 'New TLable.Caption'; LeaveCriticalSection(CritSect); But, how do I get the main thread code to be called? The thread can use SendMessage? Or is there some better/easier way (.OnIdle could check a flag set by the thread?) Thanks.

• Update configSource of XML element in web.config using Powershell by passing in Parameters

  - by Howard

  I am trying to figure out a way to update my web.config for different environments by updating the configSource for the appSettings element in the web.config. Here are the way I know how to do it. $xml.get_DocumentElement().appSettings.configSource = $replaced_test The problem is that I want one base script where I can pass in different nodes to the script that I want to change and update but I am not sure how to do it. For example, I want to be able to call a powershell script like this changeWebConfig.ps1 nodeToChange newValueofNode I hope this was clear enough. This is the code I have now. $webConfigPath = "C:\web.config" # Get the content of the config file and cast it to XML $xml = [xml](get-content $webConfigPath) #this was the trick I had been looking for $root = $xml.get_DocumentElement()."system.serviceModel".client.configSource = $replace # Save it $xml.Save($webConfigPath)

• Connect sortable lists together and update SQL using jQuery UI

  - by rebellion

  I'm using jQuery UI's sortable lists to sort items in a todo list, and the reordering of the lists works like a charm. I have several UL lists for each todo category, i.e. Design, Development, etc. I want to be able to move an item from one category to another, and jQuery UI's sortable lists plugin allows me to do this with the connectWith option parameter. But I can't seem to find how to update the database as well. The todo database table has a field for a reference to the category which is laying in it's own table. This is the current code: $('.sortable').sortable({ axis: 'y', opacity: .5, cancel: '.no-tasks', connectWith: '.sortable', update: function(){ $.ajax({ type: 'POST', url: basepath + 'task/sort_list', data: $(this).sortable('serialize') }); } }); Do I need to add another value to the AJAX's data parameter, or do the sortable plugin this for me in the serialize function?

• Appending Dataset in Core Data execution of Update through iTuneStore

  - by Yoon Lee

  So I have completed my code work. This is first time releasing the app through iTuneStore. Current state of reading Core Data (.sqlite) file is already prefetched (already has information like apple's 'Reciepie' program). Assuming I have successfully released through apple store, and decide to update my application to existing users. Say I have sqlite contents but it contains bit more information than previous SQLite file under same structure. Question 1. Every time update held to the existing user, does it removes previous ones and move new updated application? Question 2. if it is not, then HOW can I append the existing sql value?

• C# Win Forms Auto-Updating Controls

  Hello! I have a datagridview and a combobox which get populated randomly with data. However, the new data is never displayed automatically. Someone mentioned the idea of invalidating the control to force the application to redraw it and thus iterate through the contents and populate the control with the new data. Does anyone know which is the best method for implementing auto-updating controls in windows forms applications? help greatly appreciated, regards.

• C# ProgressBar design pattern

  - by MadSeb

  Hi, I'm working on a database upgrader application. The upgrader updates the schema of a database ( adds new columns, renames columns , adds new tables, new views to an existing database by executing SQL statements ). When a user wants to upgrade from version 1.0 to 2.0 , "Upgrader" objects are taken from an object factory and the "Execute" method of each "Upgrader" is called. The GUI of the application has a progress bar and each time an upgrader object performs a SQL statement the progress bar gets incremented. while (!version.Equal(CurrentVersion)) { IUpgrader myUpgrader = UpgraderFactory.GetUpgrader(version); myUpgrader.Execute(UpgradedFile,progressbar); version.Increment(); } My question is very simple : how should the upgrader object communicate with the progressbar. In the code above, the upgrader object is given direct access to the progressbar but I'm wondering if some better way of doing this or better design pattern exists. Regards, Seb

• JavaFX: Update of ListView if an element of ObservableList changes

  - by user1828169

  I would like to display a list of persons (coded in POJOS, and containing a name and surname property) using a JavaFX ListView control. I created the ListView and added the list of persons as an ObservableList. Everything works fine if I delete or add a new person to the ObservableList, but changes in the POJO do not trigger an update of the ListView. I have to remove and add the modified POJO from the ObservableList to trigger the update of the ListView. Is there any possibility to display changes in POJOS without the workaround described above?

• Update Rule in Temporal difference

  - by Betamoo

  The update rule TD(0) Q-Learning: Q(t-1) = (1-alpha) * Q(t-1) + (alpha) * (Reward(t-1) + gamma* Max( Q(t) ) ) Then take either the current best action (to optimize) or a random action (to explorer) Where MaxNextQ is the maximum Q that can be got in the next state... But in TD(1) I think update rule will be: Q(t-2) = (1-alpha) * Q(t-2) + (alpha) * (Reward(t-2) + gamma * Reward(t-1) + gamma * gamma * Max( Q(t) ) ) My question: The term gamma * Reward(t-1) means that I will always take my best action at t-1 .. which I think will prevent exploring.. Can someone give me a hint? Thanks

• How to update a table row with save button using .ajax

  - by Randall

  I have a table which has one row and only one cell will be editable. I have accomplished this with the following code. $("td#effEndDate").click(function() { if (!$(this).hasClass("edit")) { var value = jQuery.trim($(this).html()); $(this).html("<input id=\"txtEdit\" type=\"text\" value=\"" + value + "\" />"); $(this).addClass("edit"); $("#txtEdit").focus(); } }); Now this is the part where i'm stuck. After the field is updated a save button must be clicked to call the proper .ajax method to update the database. But how can I compare the previous value to the current value on a button press? Since i'm not using the onblur property where I could have saved the old value and passed it to the update function.
