• CCSprite following a sequence of CGPoints

  - by pgb

  I'm developing a line drawing game, similar to Flight Control, Harbor Master, and others in the appstore, using Cocos2D. For this game, I need a CCSprite to follow a line that the user has drawn. I'm storing a sequence of CGPoint structs in an NSArray, based on the points I get in the touchesBegin and touchesMoved messages. I now have the problem of how to make my sprite follow them. I have a tick method, that is called at the framerate speed. In that tick method, based on the speed and current position of the sprite, I need to calculate its next position. Is there any standard way to achieve this? My current approach is calculate the line between the last "reference point" and the next one, and calculate the next point in that line. The problem I have is when the sprite "turns" (moves from one segment of the line to another). Any hint will be greatly appreciated.

• WPF command/click argument

  - by Joel Barsotti

  So I have a background in ASP.NET where a button could have a click handler or a command handler and then a command argument. That pattern was great for when you had a bunch of buttons that basically needed to execute the same block of code with only a slightly different argument. Is there a collary in WPF? From what I've seen of the Command in WPF is that it revolves around an action that is independent of the control that invokes it (and still doesn't provide a way to provide an argument). Which is not really what I need.

• How significant is the bazaar performance factor?

  - by memodda

  I hear all this stuff about bazaar being slower than git. I haven't used too much distributed version control yet, but in Bazaar vs. Git on the bazaar site, they say that most complaints about performance aren't true anymore. Have you found this to be true? Is performance pretty much on par now? I've heard that speed can affect workflow (people are more likely to do good thing X if X is fast). What specific cases does performance currently affect workflow in bazaar vs other systems (especially git), and how? I'm just trying to get at why performance is of particular importance. Usually when I check something in or update it, I expect it to take a little while, but it doesn't matter. I commit/update when I have a second, so it doesn't interfere with my productivity. But then I haven't used DVCS yet, so maybe that has something to do with it?

• Is writing eSQL database agnostic?

  - by Robert Koritnik

  Using EF we can use LINQ to read data which is rather simple (especialy using fluent calls), but we have less control unless we write eSQL on our own. Is writing eSQL database actually data store independant code? So if we decide to change data store, can the same statements still be used? Is writing eSQL strings in your code pose any serious security threats similar to writing TSQL statements in plain strings? So we moved to SPs. Could we still mode eSQL scripts outside of code as well and use some other technique to make them a bit more secure?

• TFSBuild.Proj and Manual SQL Server Work Help?

  - by ScSub

  Using the VS 2008 GDR update, I have created a database project. I have created a SQL Server deployment package. I have created a database unit test. Using some wizards, the stuff got into my tfsbuild.proj file so near the end of the automated build process a database is created. I lack a little control of the whole process, I now see. What I would like to do is manually deploy the DB, run 3 custom scripts against the DB, and then manually start the DB unit test. I have other non-DB unit tests that already run. I do not want to use VSMDI or ordered unit test stuff because in out multi-developer environment it gets messy. Help!

• WPF tabcontrol styling

  - by BrettRobi

  I've got a UI with a fairly standard look and feel. It has a column of icons on the left side which when clicked open a different user control on the right side. Currently I'm using separate controls for the selection icons and the usercontrol containment. I'm having strange focus issues that I am tired of trying to mitigate and am wondering if I could style a tabcontrol to look like my UI (under the assumption a tabcontrol would not have focus issues when navigating tabs). Here is a screenshot of the basic UI. The styling is mostly about how to get the tabcontrols page selection to look like my column of icons. Anyone want to throw their hat in the ring as to how I might accomplish this with a tabcontrol? My xaml is pretty weak at this point.

• How can I bind a winforms Opacity to a TrackBar (slider)

  - by Allen

  I've got a winform with a BindingSource that has an int property named Opacity in its DataSource. I also have a TrackBar on the winform that I want to use to control the Opacity of the winform. I've bound the Value property on the TrackBar to the Opacity and that functions just fine, sliding the TrackBar will change the variable from TrackBar.Minimum (0) to TrackBar.Maximum (1). I've also bound the Opacity property of the winform to this value, however, since the TrackBar's values only go from Minimum to Maximum in +/-1 rather than +/- .1 or so (like Opacity does), it doesn't properly fade the winform. Instead, 0 will turn it opaque and 1 will turn it fully visible. I need a way to work within the architecture described above, but get the TrackBar to change its value from 0 to 1 in defined increments smaller than 1.

• Windows System Tray icons - controlling position

  - by Jamo

  I have a few old apps I've written (in Delphi) which for various reasons use a system tray icon. Most are using AppControls TacTrayIcon or some other similar component. Here's my question: How does one control the position of a tray icon? (i.e. where it is, say, relative to the system time -- 1st position/"slot", 2nd position/"slot", etc). I recall seeing a demo (C#, if memory serves) that allowed the user to "shift icon to the left" and "shift icon to the right", but don't recall how it was done. I'd like to allow the user to select what position they want to icon to appear in, for Windows 2000 - Windows 7. (I understand Windows 7 handles system tray stuff a little differently, but haven't tested that out yet). Thanks for any and all help.

• NSStepper ignores current NSTextField value

  - by JanX2

  I have the same initial problem as described in Integrate NSStepper with NSTextField: I need to have a NSTextField working with a NSStepper as being one control so that I can edit an integer value either by changing it directly on the text field or using the stepper up/down arrows. Using bindings as commented on by carlosb results in a usable UI. However, in the initial question carlosb describes the following: Problem is that if I edit the text field then click the stepper again it will forget about the value I manually edited and use the stepper's internal value. This is why I am posting a variation on this question again. carlosb's use of bindings doesn't solve this problem. This happens in both the current project I am working on and a test project I have created. The test project can be found at GitHub. You can download it there (even without git) via the "Download Source" button in the top right. Is there a clean way to solve this issue?

• What CI server and Configuration Management tools I should use

  - by Bera

  Hi ! What CI server and Configuration Management tools I should use together for a truly development and deploy maintenance. There isn't the de facto rails sustainable environment, is there? Some assumptions: • code control version ok - git (de facto tool) • test framework ok - whatever (rspec is my choice) • code coverage and analysis ok - whatever (metric-fu, for example) • server stack ok - (Passenger for example) • issue tracker (RedMine) • etc, ... I'm want to play if integrity and moonshine projects, for me it's a good for beginning, isn't it? What do you think about this? Thanks, Bruno

• php nested include behavior

  - by nute

  In many places in my code, I do things like: file1.php: <?php include('../file2.php'); file2.php: <?php include('anotherdirectory/file3.php'); Depending on the server or settings I try this on, it either sets the relative paths from the "includer" or from the "includee". This is really confusing. So file1 might try to include "../anotherdirectory/file3.php" or it might try "anotherdirectory/file3.php". What settings dictate this behavior? I want to have control over this...

• Examples of when to use PageAsyncTask (Asynchronous asp.net pages)

  - by Tony_Henrich

  From my understanding from reading about ASP.NET asynchronous pages, the method which executes when the asynchronous task begins ALWAYS EXECUTES between the prerender and the pre-render Complete events. So because the page's controls' events run between the page's load and prerender events, is it true that whatever the begin task handler (handler for BeginAsync below) produces, it can't be used in the controls' events? So for example, if the handler gets data from a database, the data can't be used in any of the controls' postback events? Would you bind data to a data control after prerender? PageAsyncTask pat = new PageAsyncTask(BeginAsync, EndAsync, null, null, true); this.RegisterAsyncTask(pat);

• Configuring Team System Code Analysis via a FxCop rules file

  - by Ian G

  Is there anyway to configure the code analysis rules in Visual Studio Team System to match those in an FxCop configuration file and keep them in sync automatically? Not all the developers on the team have TS so keeping the rules we are currently running in an FxCop file is required so everyone can run the same set, but it would nice for those with to be able to run them in the IDE. We're introducing static analysis to an existing project so turning on everything now isn't a useful option. (We are not using Foundation Server for source control, if that makes any difference.)

• Assembly reference in Silverlight class library and used only in xaml is not packaged in XAP

  - by Brandon Copeland

  I have a 3rd party library (A). That library is referenced in my Silverlight class library (B). That Silverlight class library is referenced in my Silverlight application (C). The 3rd party library is not explicitly referenced in the Silverlight application. It seems that "A" is added to my XAP if "A" is used in any class in "B" because of a chain in dependencies (C - B - A). This is the behavior I would expect and need. If "A" is never explicitly used in a C# class but only defined in Xaml, the assembly is not packaged to the XAP. Maybe "A" includes a control that is only used declaratively and never referenced otherwise. Is this behavior by design? Am I missing a property somewhere that controls this? I would prefer to not explicitly reference the third party library in my Silverlight application. What's to best practice to ensure all necessary assemblies are packaged in the XAP?

• VB.NET: How to know time for which system is idle?

  - by Daredev

  I'm making an application in which I'm implementing auto-monitor turn off when system is idle, i.e. when user is not interacting with the system. I found a link: http://www.codeproject.com/KB/system/SystemIdleTimerComponent.aspx it does provides the componenent to know when system is idle. But when I include: Public WM_SYSCOMMAND As Integer = &H112 Public SC_MONITORPOWER As Integer = &Hf170 <DllImport("user32.dll")> _ Private Shared Function SendMessage(hWnd As Integer, hMsg As Integer, wParam As Integer, lParam As Integer) As Integer End Function Private Sub button1_Click(sender As Object, e As System.EventArgs) SendMessage(Me.Handle.ToInt32(), WM_SYSCOMMAND, SC_MONITORPOWER, 2) End Sub It shows this error: Cross-thread operation not valid: Control 'Form1' accessed from a thread other than the thread it was created on.

• Delayed "rendering" of WPF/Silverlight Dependency Properties?

  - by Aardvark

  Is there a way to know the first time a Dependency Property is accessed through XAML binding so I can actually "render" the value of the property when needed? I have an object (class derived from Control) that has several PointCollection Dependency Properties that may contain 100's or 1000's of points. Each property may arrange the points differently for use in different types shapes (Polyline, Polygon, etc - its more complicated then this, but you get the idea). Via a Template different XAML objects use TemplateBinding to access these properties. Since my object uses a Template I never know what XAML shapes may be in use for my object - so I never know what Properties they may or may not bind to. I'd like to only fill-in these PointCollections when they are actually needed. Normally in .NET I'd but some logic in the Property's getter, but these are bypassed by XAML data binding. I need a WPF AND Silverlight compatible solution. I'd love a solution that avoids any additional complexities for the users of my object.

• Index was outside the bounds of the array. IndexOutOfRangeException in LINQ to SQL

  - by gtas

  Im getting this exception in the protected virtual void SendPropertyChanged(String propertyName) { if ((this.PropertyChanged != null)) { this.PropertyChanged(this, new PropertyChangedEventArgs(propertyName)); <---- HERE !!! } } of one recently table association i created, there lots of same associations around the database, and this happened in the 4 specific tables i added. Its 1...* relationship and association is Primary Table - Id (identity auto generated) Foreign PId column int not null. I just dont get it....Im using SqlMetal for generation, i regenerated the schema, rebuild, same. This is causing while inserting row in DevExpress XtraGrid, but i dont think this should be issue, same control with same functionality but for different tables works ok. I use grid's event for append value in a property when the entity creating. I disabled this but same again. Recreated the association. No change, exception occurs. Any ideas?

• Programmatic DNS

  - by Chad

  I'm a long time developer but not very experienced with DNS. Here's my problem: Our app launches servers on Amazon EC2 for clients. One client wants to use custom DNS's for every server launched instead of the normal long public DNS provided by AWS: for example server-5.demo.ourclient.com, server-6.demo.ourclient.com. What's the easiest/cleanest/best way to solve this challenge from inside our application that launches the servers and knows the Amazon public DNS? We can probably get control of demo.ourclient.com as well.... Are there nice hosted solutions with API's? Would we need to manage a DNS server for *.demo.ourclient.com? Thanks! Chad

• custom button MouseLeave event

  - by Jelle

  Hi, I made a custom button with some panels and pictureboxes. With the MouseEnter and MouseLeave I set the appropriate hover images like normal buttons. The problem is that if I move the mouse too fast over the control it sometimes doesn't trigger the MouseLeave event. This way the button is "locked" in hover state. screenshot problem: http://www.jesconsultancy.nl/images/screens/screen_prblm.png the button at the right is locked in "hover" state. How can i solve this? Thanks.

• Using Git with VB6

  - by Gavin Schultz

  Our company has a large codebase in VB6, and we currently use VSS which, for all that we hate about it, at least integrates into the VB6 IDE. My own team, which is using .NET, are now looking into alternative SCMs like my personal favourite, Git. With Git Extensions, it seems we will be able to integrate Git commands into the Visual Studio IDE pretty well. However, the question has been asked: could Git be used for our VB6 codebase too? Of course I assume the files themselves would work fine in git repositories, but no doubt developers would complain if they had to use the command-line to do all their source control. But has anyone had any experience using VB6 and Git? Any integration available from within the VB6 IDE? Or is it perhaps not that much of a hassle to not have the IDE integration? And do I get a badge for being the first to create the absurd tag combination of [vb6] and [git]?

• How to test localized winforms application?

  - by Sun

  Background: I have created sample windows application for learning to implement localization. My each form has two RESX file. One for Bulgaria and one for French(Belgium). It has default culture English(XX) To test locally currently I am programmatically changing UICulture i.e. Thread.CurrentThread.CurrentUICulture = new CultureInfo("fr-BE"); And it works fine. Problem: How can I test without forcing the UI Culture programatically? I have tried changing Control Panel Regional Options Standard and Formats to French(Belgium). That made changes to DatePickerControl and now it display the dates French. However I can still see the Button text in English, where as if I test by injecting CultureInfo programmatically it changes to french. If I am able to change the standard and formats to French do I still need to Install Multilingual User Interface Pack (MUI)?

• Is it possible to create a generic Util Function to be used in Eval Page

  - by Nassign

  I am currently binding a Nullable bit column to a listview control. When you declare a list view item I need to handle the case when the null value is used instead of just true or false. <asp:Checkbox ID="Chk1" runat="server" Checked='<%# HandleNullableBool(Eval("IsUsed")) %>' /> Then in the page I add a HandleNullableBool() function inside the ASPX page. protected static bool HandleNullableBool(object value) { return (value == null) ? false : (bool)value; } This works fine but I need to use this in several pages so I tried creating a utility class with a static HandleNullableBool. But using it in the asp page does not work. Is there a way to do this in another class instead of the ASPX page? <asp:Checkbox ID="Chk1" runat="server" Checked='<%# Util.HandleNullableBool(Eval("IsUsed")) %>' />

• How to Force a Method Call on a Property or Method of an Object in PHP?

  - by Noah Goodrich

  In my View (using Zend_View so the the view is an object), I make calls to object properties and methods to populate the template like so: <?= $this->user->name ?> // Outputs John Doe <br/> <?= $this->user->getCompany()->name ?> // Outputs Acme <br/> <?= $this->method() ?> // Outputs foobar If I make it so that all property requests (like for 'user') go through __get() is there any way that I can catch the subsequent calls so that I can force a method call on the final outputted value? For example so that I could do automatic escaping of output. As I see it right now, I either have to escape the input as it goes into the database or use compiled templates like Smarty does, or switch to assigning every variable to the View object so that it has direct control to force escaping before outputting the data.

• IHierarchyData and IHierarchicalEnumerable in Winforms

  - by Jonathan

  Hi! Currently,I know how to do a lazy implementation of the loading procedure of the nodes in a treeview control, and read the related questions in stackoverflow, but I'm also reading about IHierarchyData and IHierarchicalEnumerable interfaces in asp.net (I didn't know to code asp.net) that allow to bind a collection to a treeview in order to display the items automatically. It would like to know if I can do the same in winforms and C#. I think that the interfaces previous mentioned are not available in winforms. Thanks.

• Back button loop with IFRAMES

  - by Tim Jackson

  In my (school) website we use Iframes to display class blogs (on blogger). This works well EXCEPT if the user then clicks on (say) a photo inside the iframe. Blogger (in this case) then displays the photo in the whole browser window and the back button loops; that is if the back button is hit, the browser (IE, FF, Chrome) stays on the same page. The only way out is for the user to jump back two pages (which many of our users don't know how to do). I've read a lot of posts on back buttons and iframes and there doesn't appear to be a simple solution. Bear in mind that I don't have control over the iframe content (so no embedded back buttons in the frame are possible). Ideas anyone?
