• "CB Monitor Windows" proccess blocks XP shutdown

  - by Shiki

  I've got a home server. Simple, low-power-consumption Intel Atom based PC built by me. It runs XP since Win7 was an overkill for this poor thing. Everything was OK, always used Avast! antivirus + Spybot. However, it stopped shutting down after a while. Few days ago I noticed a "CB Monitor Windows" proccess is blocking this (didn't quit from rdp after sending the shutdown command). What is this proccess? How can I disable/remove it? Tried Malwarebytes, found ONE malware, removed it, did a reboot, no change. Avast is up-to-date, Spybot is the same. What could I do?

• Joomla + CB (Community Builder) + Google Apps

  I started wondering today if it would be possible to integrate Joomla+CB with Google apps. If that would be possible we could have one great product! The first thing that I would want to integrate is the logon-process, one login for Joomla+Google apps. Then it would be great to have some Google apps modules: - your latest e-mails - your next calendar entries - your google talk buddies online/offline - your most recent docs and spreadsheets

• iTextSharp everything works but getting strange error when opening pdf document

  - by Dmitris

  Hello everybody, I am using iTextSharp to create my PDF document on the fly. Everything works fine, and i get no errors in the code; however, when i open created PDF it gives me error saying that document will be not displayed properly because it contain errors. Here is the code bellow that gives me a problem: public class pdfevents : PdfPageEventHelper { public override void OnEndPage(PdfWriter writer, Document document) { base.OnEndPage(writer, document); PdfContentByte cb = writer.DirectContent; cb.BeginText(); cb.SetTextMatrix(20, document.GetBottom(-30)); BaseFont bf = BaseFont.CreateFont(BaseFont.TIMES_ROMAN, BaseFont.CP1252, BaseFont.NOT_EMBEDDED); cb.SetFontAndSize(bf, 10); //thats is the piece of code that makes problems //if i remove it then document displays without error cb.MoveTo(15F, document.GetBottom(-15)); cb.SetLineWidth(0.5F); cb.LineTo(document.GetRight(0), document.GetBottom(-15)); cb.Stroke(); cb.ShowText(DateTime.Now.ToLongDateString()); int n = writer.PageNumber; cb.SetTextMatrix(document.GetRight(20), document.GetBottom(-30)); cb.ShowText(" - " + n + " - "); cb.EndText(); } } If i remove following lines : //thats is the piece of code that makes problems //if i remove it then document displays without error cb.MoveTo(15F, document.GetBottom(-15)); cb.SetLineWidth(0.5F); cb.LineTo(document.GetRight(0), document.GetBottom(-15)); Then i am getting no error opening generated PDF, otherwise i can open PDF and see the document and it's content including the line. However, then i get error that document been generated with error. Can somebody tell me what is wrong ? Thanks in advance. cb.Stroke();

• How to write comments to explain the "why" behind the callback function when the function and parameter names are insufficient for that?

  - by snowmantw

  How should I approach writing comments for callback functions? I want to explain the "why" behind the function when the function and parameter names are insufficient to explain what's going on. I have always wonder why comments like this can be so ordinary in documents of libraries in dynamic languages: /** * cb: callback // where's the arguments & effects? */ func foo( cb ) Maybe the common attitude is "you can look into source code on your own after all" which pushes people into leaving minimalist comments like this. But it seems like there should be a better way to comment callback functions. I've tried to comment callbacks in Haskell way: /** * cb: Int -> Char */ func foo(cb) And to be fair, it's usually neat enough. But it gets into trouble when I need to pass some complex structure. The problem being partly due to the lack of type system: /** * cb: Int -> { err: String -> (), success: () -> Char } // too long... */ func foo(cb) Or I have tried this too: /** * cb: Int -> { err: String -> (), * success: () -> Char } // better ? */ func bar(cb) The problem is that you may put the structure in somewhere else, but you must give it a name to reference it. But then when you name a structure you're about to use immediately looks so redundant: // Somewhere else... // ResultCallback: { err: String -> (), success: () -> Char } /** * cb: Int -> ResultCallback // better ?? */ func foo(cb) And it bothers me if I follow the Java-doc like commenting style since it still seems incomplete. The comments don't tell you anything that you couldn't immediately see from looking at the function. /** * @param cb {Function} yeah, it's a function, but you told me nothing about it... * @param err {Function} where should I put this callback's argument ?? * Not to mention the err's own arguments... */ func foo(cb) These examples are JavaScript like with generic functions and parameter names, but I've encountered similar problems in other dynamic languages which allow complex callbacks.

• iTextSharp Creating a Footer Page # of #

  - by Rob

  Hi, I'm trying to create a footer on each of the pages in a PDF document using iTextSharp in the format Page # of # following the tutorial on the iText pages and the book. Though I keep getting an exception on cb.SetFontAndSize(helv, 12); - object reference not set to an object. Can anyone see the issue? Code is below. Thanks, Rob public class MyPdfPageEventHelpPageNo : iTextSharp.text.pdf.PdfPageEventHelper { protected PdfTemplate total; protected BaseFont helv; private bool settingFont = false; public override void OnOpenDocument(PdfWriter writer, Document document) { total = writer.DirectContent.CreateTemplate(100, 100); total.BoundingBox = new Rectangle(-20, -20, 100, 100); helv = BaseFont.CreateFont(BaseFont.HELVETICA, BaseFont.WINANSI, BaseFont.NOT_EMBEDDED); } public override void OnEndPage(PdfWriter writer, Document document) { PdfContentByte cb = writer.DirectContent; cb.SaveState(); string text = "Page " + writer.PageNumber + " of "; float textBase = document.Bottom - 20; float textSize = 12; //helv.GetWidthPoint(text, 12); cb.BeginText(); cb.SetFontAndSize(helv, 12); if ((writer.PageNumber % 2) == 1) { cb.SetTextMatrix(document.Left, textBase); cb.ShowText(text); cb.EndText(); cb.AddTemplate(total, document.Left + textSize, textBase); } else { float adjust = helv.GetWidthPoint("0", 12); cb.SetTextMatrix(document.Right - textSize - adjust, textBase); cb.ShowText(text); cb.EndText(); cb.AddTemplate(total, document.Right - adjust, textBase); } cb.RestoreState(); } public override void OnCloseDocument(PdfWriter writer, Document document) { total.BeginText(); total.SetFontAndSize(helv, 12); total.SetTextMatrix(0, 0); int pageNumber = writer.PageNumber - 1; total.ShowText(Convert.ToString(pageNumber)); total.EndText(); } }

• Combobox having values but not showing text

  - by ras

  hi, I'm using GWT-EXT combobox. My problem is when I render the combobox, it's having as many rows as it has values but all the rows are empty means text is not shown. Here's my code. Combobox cb = new Combobox(); cb.setForceSelection(true); cb.setMinChars(1); cb.setWidth(200); cb.setStore(store); // Store is perfectly loaded in combobox cb.setDisplayField("ReportName"); cb.setMode(ComboBox.LOCAL); cb.setTriggerAction(ALL); cb.setEmptyText("--Select--"); cb.setLoadingText("Searching..."); cb.setTypeAhead(true); cb.setSelectOnFocus(true); All other code is working fine. I'm sure for one thing that this problem is related to one of the functions of Combobox. Thanks in advance.

• How can I solve the same problems a CB-architecture is trying to solve without using hacks? [on hold]

  - by Jefffrey

  A component based system's goal is to solve the problems that derives from inheritance: for example the fact that some parts of the code (that are called components) are reused by very different classes that, hypothetically, would lie in a very different branch of the inheritance tree. That's a very nice concept, but I've found out that CBS is often hard to accomplish without using ugly hacks. Implementations of this system are often far from clean. But I don't want to discuss this any further. My question is: how can I solve the same problems a CBS try to solve with a very clean interface? (possibly with examples, there are a lot of abstract talks about the "perfect" design already). Here's an example I was going for before realizing I was just reinventing inheritance again: class Human { public: Position position; Movement movement; Sprite sprite; // other human specific components }; class Zombie { Position position; Movement movement; Sprite sprite; // other zombie specific components }; After writing that I realized I needed an interface, otherwise I would have needed N containers for N different types of objects (or to use boost::variant to gather them all together). So I've thought of polymorphism (move what systems do in a CBS design into class specific functions): class Entity { public: virtual void on_event(Event) {} // not pure virtual on purpose virtual void on_update(World) {} virtual void on_draw(Window) {} }; class Human { private: Position position; Movement movement; Sprite sprite; public: virtual void on_event(Event) { ... } virtual void on_update(World) { ... } virtual void on_draw(Window) { ... } }; class Zombie { private: Position position; Movement movement; Sprite sprite; public: virtual void on_event(Event) { ... } virtual void on_update(World) { ... } virtual void on_draw(Window) { ... } }; Which was nice, except for the fact that now the outside world would not even be able to know where a Human is positioned (it does not have access to its position member). That would be useful to track the player position for collision detection or if on_update the Zombie would want to track down its nearest human to move towards him. So I added const Position& get_position() const; to both the Zombie and Human classes. And then I realized that both functionality were shared, so it should have gone to the common base class: Entity. Do you notice anything? Yes, with that methodology I would have a god Entity class full of common functionality (which is the thing I was trying to avoid in the first place).

• iTextSharp 5.0 Footer is not displaying

  - by Rick Make

  I am trying to create a simple footer that would display on the bottom of each page of the pdf document. I created a class that inherits from PdfPageEventHelper and it is set properly because the OnEndPage() method is called. But my temporary footer is not displaying. Is there something wrong that I am doing in my OnEndPage() method: public override void OnEndPage(PdfWriter writer, Document document) { base.OnEndPage(writer, document); int pageN = writer.PageNumber; String text = "Page " + pageN + " of "; float len = bf.GetWidthPoint(text, 8); Rectangle pageSize = document.PageSize; cb.SetRGBColorFill(100, 100, 100); cb.BeginText(); cb.SetFontAndSize(bf, 8); cb.SetTextMatrix(pageSize.GetLeft(40), pageSize.GetBottom(30)); cb.ShowText(text); cb.EndText(); cb.AddTemplate(template, pageSize.GetLeft(40) + len, pageSize.GetBottom(30)); cb.BeginText(); cb.SetFontAndSize(bf, 8); cb.ShowTextAligned(PdfContentByte.ALIGN_RIGHT, "Printed On " + PrintTime.ToString(), pageSize.GetRight(40), pageSize.GetBottom(30), 0); cb.EndText(); }

• itextsharp PdfCopy and landscape pages

  - by Andreas Rehm

  I'm using itextsharp to join mutiple pdf documents and add a footer. My code works fine - except for landscape pages - it isn't detecting the page rotation - the footer is not centerd for landscape: public static int AddPagesFromStream(Document document, PdfCopy pdfCopy, Stream m, bool addFooter, int detailPages, string footer, int footerPageNumOffset, int numPages, string pageLangString, string printLangString) { CreateFont(); try { m.Seek(0, SeekOrigin.Begin); var reader = new PdfReader(m); // get page count var pdfPages = reader.NumberOfPages; var i = 0; // add pages while (i < pdfPages) { i++; // import page with pdfcopy var page = pdfCopy.GetImportedPage(reader, i); // get page center float posX; float posY; var rotation = page.BoundingBox.Rotation; if (rotation == 0 || rotation == 180) { posX = page.Width / 2; posY = 0; } else { posX = page.Height / 2; posY = 20f; } var ps = pdfCopy.CreatePageStamp(page); var cb = ps.GetOverContent(); // add footer cb.SetColorFill(BaseColor.WHITE); var gs1 = new PdfGState {FillOpacity = 0.8f}; cb.SetGState(gs1); cb.Rectangle(0, 0, document.PageSize.Width, 46f + posY); cb.Fill(); // Text cb.SetColorFill(BaseColor.BLACK); cb.SetFontAndSize(baseFont, 7); cb.BeginText(); // create text var pages = string.Format(pageLangString, i + footerPageNumOffset, numPages); cb.ShowTextAligned(PdfContentByte.ALIGN_CENTER, printLangString, posX, 40f + posY, 0f); cb.ShowTextAligned(PdfContentByte.ALIGN_CENTER, footer, posX, 28f + posY, 0f); cb.ShowTextAligned(PdfContentByte.ALIGN_CENTER, pages, posX, 20f + posY, 0f); cb.EndText(); ps.AlterContents(); // add page to new pdf pdfCopy.AddPage(page); } // close PdfReader reader.Close(); // return number of pages return i; } catch (Exception e) { Console.WriteLine(e); return 0; } } How do I detect the page rotation (e.g. landscape) format in this case? The given example works for PdfReader but not for PdfCopy. Edit: Why do I need PdfCopy? I tried copying a word pdf export. Some word hyperlinks will not work when you try to copy pages with PdfReader. Only PdfCopy transfers all needed page informations. Edit: (SOLVED) You need to use reader.GetPageRotation(i);

• game speed problem

  HI..I made a little game.But this game works on every computer with different speed.I think it is about resolution.I used every thing in paintcomponent.and If I change screen size the game goes slower or faster.And if i run this game on another computer wich has different resolution it also works different. This is my game http://rapidshare.com/files/364597095/ShooterGame.2.6.0.jar and here code public class Shooter extends JFrame implements KeyListener, Runnable { JFrame frame = new JFrame(); String player; Font startFont, startSubFont, timerFont,healthFont; Image img; Image backGround; Graphics dbi; URL url1 = this.getClass().getResource("Images/p2.gif"); URL url2 = this.getClass().getResource("Images/p3.gif"); URL url3 = this.getClass().getResource("Images/p1.gif"); URL url4 = this.getClass().getResource("Images/p4.gif"); URL urlMap = this.getClass().getResource("Images/zemin.jpg"); Player p1 = new Player(5, 150, 10, 40, Color.GREEN, url3); Computer p2 = new Computer(750, 150, 10, 40, Color.BLUE, url1); Computer p3 = new Computer(0, 0, 10, 40, Color.BLUE, url2); Computer p4 = new Computer(0, 0, 10, 40, Color.BLUE, url4); ArrayList<Bullets> b = new ArrayList<Bullets>(); ArrayList<CBullets> cb = new ArrayList<CBullets>(); Thread sheap; boolean a, d, w, s; boolean toUp, toDown; boolean GameOver; boolean Level2; boolean newGame, resart, pause; int S, E; int random; int cbSpeed = 0; long timeStart, timeEnd; int timeElapsed; long GameStart, GameEnd; int GameScore; int Timer = 0; int timerStart, timerEnd; public Shooter() { sheap = new Thread(this); sheap.start(); startFont = new Font("Tiresias PCFont Z", Font.BOLD + Font.ITALIC, 32); startSubFont = new Font("Tiresias PCFont Z", Font.BOLD + Font.ITALIC, 25); timerFont = new Font("Tiresias PCFont Z", Font.BOLD + Font.ITALIC, 16); healthFont = new Font("Tiresias PCFont Z", Font.BOLD + Font.ITALIC, 16); setTitle("Shooter 2.5.1"); setBounds(350, 250, 800, 600); // setResizable(false); setBackground(Color.black); setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); addKeyListener(this); a = d = w = s = false; toUp = toDown = true; GameOver = true; newGame = true; Level2 = false; S = E = 0; setVisible(true); } public void paint(Graphics g) { img = createImage(getWidth(), getHeight()); dbi = img.getGraphics(); paintComponent(dbi); g.drawImage(img, 0, 0, this); } public void paintComponent(Graphics g) { repaint(); timeStart = System.currentTimeMillis(); backGround = Toolkit.getDefaultToolkit().getImage(urlMap); g.drawImage(backGround, 0, 0, null); g.setColor(Color.red); g.setFont(healthFont); g.drawString("" + player + " Health : " + p1.health, 30, 50); g.setColor(Color.red); g.drawString("Computer Health : " + (p2.health + p3.health + p4.health), 600, 50); g.setColor(Color.BLUE); g.setFont(timerFont); g.drawString("Time : " + Timer, 330, 50); if (newGame) { g.setColor(Color.LIGHT_GRAY); g.setFont(startFont); g.drawString("Well Come To Shoot Game", 200, 190); g.drawString("Press ENTER To Start", 250, 220); g.setColor(Color.LIGHT_GRAY); g.setFont(startSubFont); g.drawString("Use W,A,S,D and Space For Fire", 200, 250); g.drawString("GOOD LUCK", 250, 280); newGame(); } if (!GameOver) { for (Bullets b1 : b) { b1.draw(g); } for (CBullets b2 : cb) { b2.draw(g); } update(); // Here MOvements for Player and For Fires } if (p1.health <= 0) { g.setColor(p2.col); g.setFont(startFont); g.drawString("Computer Wins ", 200, 190); g.drawString("Press Key R to Restart ", 200, 220); GameOver = true; } else if (p2.health <= 0 && p3.health <= 0 && p4.health <= 0) { g.setColor(p1.col); g.setFont(startFont); g.drawString(""+player+" Wins ", 200, 190); g.drawString("Press Key R to Resart ", 200, 220); GameOver = true; g.setColor(Color.MAGENTA); g.drawString(""+player+"`s Score is " + Timer, 200, 120); } if (Level2) { if (p3.health >= 0) { p3.draw(g); for (CBullets b3 : cb) { b3.draw(g); } } else { p3.x = 1000; } if (p4.health >= 0) { p4.draw(g); for (CBullets b4 : cb) { b4.draw(g); } } else { p4.x = 1000; } } if (p1.health >= 0) { p1.draw(g); } if (p2.health >= 0) { p2.draw(g); } else { p2.x = 1000; } } public void update() { if (w && p1.y > 54) { p1.moveUp(); } if (s && p1.y < 547) { p1.moveDown(); } if (a && p1.x > 0) { p1.moveLeft(); } if (d && p1.x < 200) { p1.moveRight(); } random = 1 * (int) (Math.random() * 100); if (random > 96) { if (p2.health >= 0) { CBullets bo = p2.getCBull(); bo.xVel =-1-cbSpeed; cb.add(bo); } if (Level2) { if (p3.health >= 0) { CBullets bo1 = p3.getCBull(); bo1.xVel = -2-cbSpeed; cb.add(bo1); } if (p4.health >= 0) { CBullets bo2 = p4.getCBull(); bo2.xVel = -4-cbSpeed; cb.add(bo2); } } } if (S == 1) { if (p1.health >= 0) { Bullets bu = p1.getBull(); bu.xVel = 5; b.add(bu); S += 1; } } //Here Also Problem ..

• Combo box in a scrollable panel causing problems

  - by Dennis

  I have a panel with AutoScroll set to true. In it, I am programmatically adding ComboBox controls. If I add enough controls to exceed the viewable size of the panel a scroll bar appears (so far so good). However, if I open one of the combo boxes near the bottom of the viewable area the combo list isn't properly displayed and the scrollable area seems to be expanded. This results in all of the controls being "pulled" to the new bottom of the panel with some new blank space at the top. If I continue to tap on the drop down at the bottom of the panel the scrollable area will continue to expand indefinitely. I'm anchoring the controls to the left, right and top so I don't think anchoring is involved. Is there something obvious that could be causing this? Update: It looks like the problem lies with anchoring the controls to the right. If I don't anchor to the right then I don't get the strange behavior. However, without right anchoring the control gets cut off by the scroll bar. Here's a simplified test case I built that shows the issue: public Form1() { InitializeComponent(); Panel panel = new Panel(); panel.Size = new Size(80, 200); panel.AutoScroll = true; for (int i = 0; i < 10; ++i) { ComboBox cb = new ComboBox(); cb.Anchor = AnchorStyles.Left | AnchorStyles.Right | AnchorStyles.Top; cb.Items.Add("Option 1"); cb.Items.Add("Option 2"); cb.Items.Add("Option 3"); cb.Items.Add("Option 4"); cb.Location = new Point(0, i * 24); panel.Controls.Add(cb); } Controls.Add(panel); } If you scroll the bottom of the panel and tap on the combo boxes near the bottom you'll notice the strange behavior.

• Is it possible to order by a composite key with JPA and CriteriaBuilder

  - by Kjir

  I would like to create a query using the JPA CriteriaBuilder and I would like to add an ORDER BY clause. This is my entity: @Entity @Table(name = "brands") public class Brand implements Serializable { public enum OwnModeType { OWNER, LICENCED } @EmbeddedId private IdBrand id; private String code; //bunch of other properties } Embedded class is: @Embeddable public class IdBrand implements Serializable { @ManyToOne private Edition edition; private String name; } And the way I am building my query is like this: CriteriaBuilder cb = em.getCriteriaBuilder(); CriteriaQuery<Brand> q = cb.createQuery(Brand.class).distinct(true); Root<Brand> root = q.from(Brand.class); if (f != null) { f.addCriteria(cb, q, root); f.addOrder(cb, q, root, sortCol, ascending); } return em.createQuery(q).getResultList(); And here are the functions called: public void addCriteria(CriteriaBuilder cb, CriteriaQuery<?> q, Root<Brand> r) { } public void addOrder(CriteriaBuilder cb, CriteriaQuery<?> q, Root<Brand> r, String sortCol, boolean ascending) { if (ascending) { q.orderBy(cb.asc(r.get(sortCol))); } else { q.orderBy(cb.desc(r.get(sortCol))); } } If I try to set sortCol to something like "id.edition.number" I get the following error: javax.ejb.EJBException: java.lang.IllegalArgumentException: Unable to resolve attribute [id.name] against path Any idea how I could accomplish that? I tried searching online, but I couldn't find a hint about this... Also would be great if I could do a similar ORDER BY when I have a @ManyToOne relationship (for instance, "id.edition.number")

• Juju Zookeeper & Provisioning Agent Not Deployed

  - by Keith Tobin

  I am using juju with the openstack provider, i expected that when i bootstrap that zookeeper and provisioning agent would get deployed on the bootstrap vm in openstack. This dose not seem to be the case. the bootstrap vm gets deployed but it seems that nothing gets deployed to the VM. See logs below, I may be missing something, also how is it possible to log on the bootstrap vm. Could I manual deploy, if so what do I need to do.

• Winforms controls and "generic" events handlers. How can I do this?

  - by Yanko Hernández Alvarez

  In the demo of the ObjectListView control there is this code (in the "Complex Example" tab page) to allow for a custom editor (a ComboBox) (Adapted to my case and edited for clarity): EventHandler CurrentEH; private void ObjectListView_CellEditStarting(object sender, CellEditEventArgs e) { if (e.Column == SomeCol) { ISomeInterface M = (e.RowObject as ObjectListView1Row).SomeObject; //(1) ComboBox cb = new ComboBox(); cb.Bounds = e.CellBounds; cb.DropDownStyle = ComboBoxStyle.DropDownList; cb.DataSource = ISomeOtherObjectCollection; cb.DisplayMember = "propertyName"; cb.DataBindings.Add("SelectedItem", M, "ISomeOtherObject", false, DataSourceUpdateMode.Never); e.Control = cb; cb.SelectedIndexChanged += CurrentEH = (object sender2, EventArgs e2) => M.ISomeOtherObject = (ISomeOtherObject)((ComboBox)sender2).SelectedValue; //(2) } } private void ObjectListView_CellEditFinishing(object sender, CellEditEventArgs e) { if (e.Column == SomeCol) { // Stop listening for change events ((ComboBox)e.Control).SelectedIndexChanged -= CurrentEH; // Any updating will have been down in the SelectedIndexChanged // event handler. // Here we simply make the list redraw the involved ListViewItem ((ObjectListView)sender).RefreshItem(e.ListViewItem); // We have updated the model object, so we cancel the auto update e.Cancel = true; } } I have too many other columns with combo editors inside objectlistviews to use a copy& paste strategy (besides, copy&paste is a serious source of bugs), so I tried to parameterize the code to keep the code duplication to a minimum. ObjectListView_CellEditFinishing is a piece of cake: HashSet<OLVColumn> cbColumns = new HashSet<OLVColumn> (new OLVColumn[] { SomeCol, SomeCol2, ...}; private void ObjectListView_CellEditFinishing(object sender, CellEditEventArgs e) { if (cbColumns.Contains(e.Column)) ... but ObjectListView_CellEditStarting is the problematic. I guess in CellEditStarting I will have to discriminate each case separately: private void ObjectListView_CellEditStarting(object sender, CellEditEventArgs e) { if (e.Column == SomeCol) // code to create the combo, put the correct list as the datasource, etc. else if (e.Column == SomeOtherCol) // code to create the combo, put the correct list as the datasource, etc. And so on. But how can I parameterize the "code to create the combo, put the correct list as the datasource, etc."? Problem lines are (1) Get SomeObject. the property NAME varies. (2) Set ISomeOtherObject, the property name varies too. The types vary too, but I can cover those cases with a generic method combined with a not so "typesafe" API (for instance, the cb.DataBindings.Add and cb.DataSource both use an object) Reflection? more lambdas? Any ideas? Any other way to do the same? PS: I want to be able to do something like this: private void ObjectListView_CellEditStarting(object sender, CellEditEventArgs e) { if (e.Column == SomeCol) SetUpCombo<ISomeInterface>(ISomeOtherObjectCollection, "propertyName", SomeObject, ISomeOtherObject); else if (e.Column == SomeOtherCol) SetUpCombo<ISomeInterface2>(ISomeOtherObject2Collection, "propertyName2", SomeObject2 ISomeOtherObject2); and so on. Or something like that. I know, parameters SomeObject and ISomeOtherObject are not real parameters per see, but you get the idea of what I want. I want not to repeat the same code skeleton again and again and again. One solution would be "preprocessor generics" like C's DEFINE, but I don't thing c# has something like that. So, does anyone have some alternate ideas to solve this?

• t:commandSortHeader not being styled

  - by JBristow

  I've got the following JSF: <t:column styleClass="cb-status-column"> <f:facet name="header"> <t:commandSortHeader columnName="externalStatus" styleClass="cb-status-column"> Status </t:commandSortHeader> </f:facet> <h:outputText value="#{tx.externalStatus}" title="#{tx.externalStatus}"/> </t:column> Unfortunately, it renders like this: <th> <a href="#" onclick="return oamSubmitForm('transactionsTableForm','cb-activity-table:j_id131');" id="cb-activity-table:j_id131"> Status </a> </th> How do I get it to look like this: <th class="cb-status-column"> <a href="#" onclick="return oamSubmitForm('transactionsTableForm','cb-activity-table:j_id131');" id="cb-activity-table:j_id131"> Status </a> </th>

• CheckBox won't toggle in Android ListView with focusable="false"

  - by user3563124

  I'm creating a ListView with a custom Adapter for displaying my entries. Each row contains a checkbox, and my adapter contains the following code: CheckBox cb = (CheckBox) v.findViewById(R.id.item_sold); cb.setChecked(p.isSold); setupCheckboxListener(cb, v, position); ... private void setupCheckboxListener(CheckBox check, final View v, final int position) { check.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { CheckBox cb = (CheckBox) v; if (cb.isChecked()) { System.out.println("Should become false!"); cb.setChecked(false); } else { System.out.println("Should become true!"); cb.setChecked(true); } } }); My row XML file includes the following: <CheckBox android:id="@+id/item_sold" android:layout_width="0dp" android:layout_height="wrap_content" android:layout_weight="0.10" android:layout_gravity="center" android:gravity="center" android:focusable="false" android:clickable="false"/> But anytime I press one of the checkboxes, check.isChecked() returns true, even if the box is unchecked. I even checked to make sure that the checkboxes were distinct and weren't picking up just the last value/etc. Setting up the listeners inline instead of in a method doesn't seem to help, either. It's literally just the isChecked() condition that isn't working appropriately - it seems to always give me the inverse value. Setting an onClick on the row is not acceptable in this case because I need to allow row selection for something else. What could be causing this issue?

My code is: <script type="text/javascript" charset="utf-8" src="js/ChildBrowser.js"></script> <script> function onDeviceReady() { childbrowser = ChildBrowser.install(); var root = this; cb = window.plugins.childBrowser; if(cb != null) { cb.onLocationChange = function(loc){ root.locChanged(loc); }; cb.onClose = function(){root.onCloseBrowser(); }; cb.onOpenExternal = function(){root.onOpenExternal(); }; //cb.showWebPage(“http://google.com”); } } function onCloseBrowser() { console.log(“onCloseBrowser!”); } function locChanged(loc) { console.log(“locChanged!”); } function onOpenExternal() { alert(“onOpenExternal!”); } <body onLoad=”onBodyLoad()”> <a href=”#” onclick=’cb.showWebPage(“http://www.google.com”);’>Click Me</a>

• Joomla SMTP Configuration Issue

  - by msargenttrue

  I'm having an issue with the SMTP setup of my Joomla website when trying to send mass emails through the CB Mailing (Mass Email) extension. I receive this error: SMTP Error! The following recipients failed: Number of users to whom e-mail was sent: 0 (Total in list: 1) The old version of this websites mass emailer worked fine, however, in order to add Kunena Forum and maintain compatibility I had to make several upgrades to the site. Both the new version and old verson configurations are outlined below. Server for Website: Mac OS X Server 10.4.11, Apache 1.3.4.1, PHP 5.2.3, MySQL 4.1.22 Server for SMTP: Eudora Internet Mail Server 3.3.9 (EIMS Server X) New Configuration: Joomla 1.5.25, Community Builder 1.7.1, CB Paid Subscriptions (CB Subs) 1.2.2, CBMailing 2.3.4, Kunena Forum 1.7.0, Legacy 1.0 plug-in disabled Mail Settings (New Config): Mailer: SMTP Server Mail from: [email protected] From Name: CASPA Sendmail Path: /usr/sbin/sendmail SMTP Authentication: Yes SMTP Security: None SMTP Port: 25 SMTP Username: [email protected] SMTP Password: xxxxxxx SMTP Host: 209.48.40.194 Old Configuration (Working SMTP Configuration): Joomla 1.5.9, Community Builder 1.2, CB Paid Subscriptions (CB Subs) 1.0.3, CB Mailing 2.1, Legacy 1.0 plug-in enabled Mail Settings (Old Config): Mailer: SMTP Server Mail from: [email protected] From Name: CASPA Sendmail Path: /usr/sbin/sendmail SMTP Authentication: Yes SMTP Username: [email protected] SMTP Password: xxxxxxx SMTP Host: 209.48.40.194 (Notice how the older version of Joomla is missing the 2 fields: SMTP Security and SMTP Port) Thanks in advance!

• a script translatable to JavaScript with callback-hell automatic avoider :-)

  - by m1uan

  I looking for "translator" for JavaScript like already is CoffeScript, which will be work for example with forEach (inspired by Groovy) myArray.forEach() -> val, idx { // do something with value and idx } translate to JavaScript myArray.forEach(function(val, idx){ // do something with value and idx }); or something more usefull... function event(cb){ foo()-> err, data1; bar(data1)-> err, data2; cb(data2); } the method are encapsulated function event(cb){ foo(function(err,data1){ bar(data1, function(err, data2) { cb(data2); }); }); } I want ask if similar "compiler" to JavaScript like this even better already doesn't exists? What would be super cool... my code in nodejs looks mostly like this :-) function dealer(cb){ async.parallel([ function(pcb){ async.watterfall([function(wcb){ first(function(a){ wcb(a); }); }, function(a, wcb){ thirt(a, function(c){ wcb(c); }); fourth(a, function(d){ // dealing with “a” as well and nobody care my result }); }], function(err, array_with_ac){ pcb(array_with_ac); }); }, function(pcb){ second(function(b){ pcb(b);}); }], function(err, data){ cb(data[0][0]+data[1]+data[0][1]); // dealing with “a” “b” and “c” not with “d” }); } but, look how beautiful and readable the code could be: function dealer(cb){ first() -> a; second() -> b; third(a) -> c; // dealing with “a” fourth(a) -> d; // dealing with “a” as well and nobody care about my result cb(a+b+c); // dealing with “a” “b” and “c” not with “d” } yes this is ideal case when the translator auto-decide, method need to be run as parallel and method need be call after finish another method. I can imagine it's works Please, do you know about something similar? Thank you for any advice;-)

• Passing Data thru NSTimer UserInfo

  - by zorro2b

  I a trying to pass data thru userInfo for an NSTimer call. What is the best way to do this? I am trying to use an NSDictionary, this is simple enough when I have objective c objects, but what about other data? I want to do something like this, which doesn't work as is: - (void) play:(SystemSoundID)sound target:(id)target callbackSelector:(SEL)selector { NSLog(@"pause ipod"); [iPodController pause]; theSound = sound; NSMutableDictionary *cb = [[NSMutableDictionary alloc] init]; [cb setObject:(id)&sound forKey:@"sound"]; [cb setObject:target forKey:@"target"]; [cb setObject:(id)&selector forKey:@"selector"]; [NSTimer scheduledTimerWithTimeInterval:0 target:self selector: @selector(notifyPause1:) userInfo:(id)cb repeats:NO]; }

• How to set variable before callback is called?

  - by user1995327

  I'm trying to design a webpage... I have a function that I call get all info needed for an idividuals home page. A snippet of the codes is: exports.getHomePageData = function(userId, cb) { var pageData = {}; pageData.userFullName = dbUtil.findNameByUserId(userId, function(err){ if (err) cb(err); }); pageData.classes = dbUtil.findUserClassesByUserId(userId, function(err){ if (err) cb(err); }); cb(pageData); } The problem I'm having is the cb(pageData) is being called before I even finish setting the elements. I've seen that people use the async library to solve this but I was wondering if there was any other way for me to do it without needing more modules... Thanks!

• In Perl, how can a subroutine get a coderef that points to itself?

  - by hillu

  For learning purposes, I am toying around with the idea of building event-driven programs in Perl and noticed that it might be nice if a subroutine that was registered as an event handler could, on failure, just schedule another call to itself for a later time. So far, I have come up with something like this: my $cb; my $try = 3; $cb = sub { my $rc = do_stuff(); if (!$rc && --$try) { schedule_event($cb, 10); # schedule $cb to be called in 10 seconds } else { do_other_stuff; } }; schedule_event($cb, 0); # schedule initial call to $cb to be performed ASAP Is there a way that code inside the sub can access the coderef to that sub so I could do without using an extra variable? I'd like to schedule the initial call like this. schedule_event( sub { ... }, 0); I first thought of using caller(0)[3], but this only gives me a function name, (__ANON__ if there's no name), not a code reference that has a pad attached to it.
