  • jQuery validator not working in unit testing

    - by Dbugger
    I have this small HTML file: <html> <head></head> <body> <form id='MyForm'> <input type='text' required /> <input type='submit' /> </form> <script src="/js/jquery-1.9.0.js"></script> <script src="/js/jquery.validate.js"></script> <script> var validator = $("#MyForm").validate(); alert(validator.form()); </script> </body> </html> This alerts me with "false", which is the expected behaviour. The problem comes when I go to unit testing, with js-test-driver: TestCase("MyTests", { setUp: function() { this.myform = "<form id='MyForm'><input type='text' required /><input type='submit' /></form>"; this.validator = $(this.myform).validate(); jstestdriver.console.log("Does the form validate? " + this.validator.form()); }, test_empty: function() { }, }); This code returns me the string Does the form validate? true This is a simplified version of my project of course, but the point is that I dont seem to be able to unit test the validation module im developing, since the jQuery validate plugin doesnt seem to work. What am I missing?

  • Why doesn't every class in the .Net framework have a corresponding interface?

    - by Thorsten Lorenz
    Since I started to develop in a test/behavior driven style, I appreciated the ability to mock out every dependency. Since mocking frameworks like Moq work best when told to mock an interface, I now implement an interface for almost every class I create b/c most likely I will have to mock it out in a test eventually. Well, and programming to an interface is good practice, anyways. At times, my classes take dependencies on .Net classes (e.g. FileSystemWatcher, DispatcherTimer). It would be great in that case to have an interface, so I could depend on an IDispatcherTimer instead, to be able to pass it a mock and simulate its behavior to see if my system under test reacts correctly. Unfortunately both of above mentioned classes do not implement such interfaces, so I have to resort to creating adapters, that do nothing else but inherit from the original class and conform to an interface, that I then can use. Here is such an adapter for the DispatcherTimer and the corresponding interface: using System; using System.Windows.Threading; public interface IDispatcherTimer { #region Events event EventHandler Tick; #endregion #region Properties Dispatcher Dispatcher { get; } TimeSpan Interval { get; set; } bool IsEnabled { get; set; } object Tag { get; set; } #endregion #region Public Methods void Start(); void Stop(); #endregion } /// <summary> /// Adapts the DispatcherTimer class to implement the <see cref="IDispatcherTimer"/> interface. /// </summary> public class DispatcherTimerAdapter : DispatcherTimer, IDispatcherTimer { } Although this is not the end of the world, I wonder, why the .Net developers didn't take the minute to make their classes implement these interfaces from the get go. It puzzles me especially since now there is a big push for good practices from inside Microsoft. Does anyone have any (maybe inside) information why this contradiction exists?

  • C# UserControl Validation

    - by Barry
    Hi, I have a UserControl with a Tab Control containing three tabs. Within the tabs are multiple controls - Datetimepickers, textboxes, comboboxes. There is also a Save button which when clicked, calls this.ValidateChildren(ValidationConstraints.Enabled) Now, I click save and a geniune validation error occurs. I correct the error and then click save again - valdiation errors occur on comboboxes on a different tab. If I navigate to this tab and click save, everything works fine. How can this be? I haven't changed any values in the comboboxes so how can the fail validation then pass validation? The comboboxes are bound to a dataset with their selectedValue and Text set. I just don't understand what is happening here. This behaviour also occurs for some textboxes too. The validation rule is that they have to be a decimal - the default value is zero, which is allowed. The same thing happens, they fail validation the first time - I make no changes, click save again and they pass validation. If you need any further information please let me know thanks Barry

  • Regex: Use start of line/end of line signs (^ or $) in different context

    - by fgysin
    While doing some small regex task I came upon this problem. I have a string that is a list of tags that looks e.g like this: foo,bar,qux,garp,wobble,thud What I needed to do was to check if a certain tag, e.g. 'garp' was in this list. (What it finally matches is not really important, just if there is a match or not.) My first and a bit stupid try at this was to use the following regex: [^,]garp[,$] My idea was that before 'garp' there should either be the start of the line/string or a comma, after 'garp' there should be either a comma or the end of the line/string. Now, it is instantly obvious that this regex is wrong: Both ^ and $ change their behaviour in the context of the character class [ ]. What I finally came up with is the following: ^garp$|^garp,|,garp,|,garp$ This regex just handles the 4 cases one by one. (Tag at beginning of list, in the center, at the end, or as the only element of the list.) The last regex is somehow a bit ugly in my eyes and just for funs sake I'd like to make it a bit more elegant. Is there a way how the start of line/end of line characters (^ and $) can be used in the context of character classes?

  • Jenkins slave jobs failing on "Unexpected termination of channel"

    - by Clark Wright
    I am currently seeing a set of errors across my builds. Is this expected behaviour if you loose Jenkins (say to a box crash, or a kill -9)? Or is there something worse going on (like a bad network connection)? The stack and error is: FATAL: hudson.remoting.RequestAbortedException: java.io.IOException: Unexpected termination of the channel hudson.remoting.RequestAbortedException: hudson.remoting.RequestAbortedException: java.io.IOException: Unexpected termination of the channel at hudson.remoting.Request.call(Request.java:149) at hudson.remoting.Channel.call(Channel.java:681) at hudson.remoting.RemoteInvocationHandler.invoke(RemoteInvocationHandler.java:158) at $Proxy175.join(Unknown Source) at hudson.Launcher$RemoteLauncher$ProcImpl.join(Launcher.java:861) at hudson.Launcher$ProcStarter.join(Launcher.java:345) at hudson.tasks.CommandInterpreter.perform(CommandInterpreter.java:82) at hudson.tasks.CommandInterpreter.perform(CommandInterpreter.java:58) at hudson.tasks.BuildStepMonitor$1.perform(BuildStepMonitor.java:19) at hudson.model.AbstractBuild$AbstractRunner.perform(AbstractBuild.java:703) at hudson.model.Build$RunnerImpl.build(Build.java:178) at hudson.model.Build$RunnerImpl.doRun(Build.java:139) at hudson.model.AbstractBuild$AbstractRunner.run(AbstractBuild.java:473) at hudson.model.Run.run(Run.java:1410) at hudson.model.FreeStyleBuild.run(FreeStyleBuild.java:46) at hudson.model.ResourceController.execute(ResourceController.java:88) at hudson.model.Executor.run(Executor.java:238) Caused by: hudson.remoting.RequestAbortedException: java.io.IOException: Unexpected termination of the channel at hudson.remoting.Request.abort(Request.java:273) at hudson.remoting.Channel.terminate(Channel.java:732) at hudson.remoting.Channel$ReaderThread.run(Channel.java:1157) Caused by: java.io.IOException: Unexpected termination of the channel at hudson.remoting.Channel$ReaderThread.run(Channel.java:1133) Caused by: java.io.EOFException at java.io.ObjectInputStream$BlockDataInputStream.peekByte(ObjectInputStream.java:2554) at java.io.ObjectInputStream.readObject0(ObjectInputStream.java:1297) at java.io.ObjectInputStream.readObject(ObjectInputStream.java:351) at hudson.remoting.Channel$ReaderThread.run(Channel.java:1127)

  • Reference for proper handling of PID file on Unix

    - by bignose
    Where can I find a well-respected reference that details the proper handling of PID files on Unix? On Unix operating systems, it is common practice to “lock” a program (often a daemon) by use of a special lock file: the PID file. This is a file in a predictable location, often ‘/var/run/foo.pid’. The program is supposed to check when it starts up whether the PID file exists and, if the file does exist, exit with an error. So it's a kind of advisory, collaborative locking mechanism. The file contains a single line of text, being the numeric process ID (hence the name “PID file”) of the process that currently holds the lock; this allows an easy way to automate sending a signal to the process that holds the lock. What I can't find is a good reference on expected or “best practice” behaviour for handling PID files. There are various nuances: how to actually lock the file (don't bother? use the kernel? what about platform incompatibilities?), handling stale locks (silently delete them? when to check?), when exactly to acquire and release the lock, and so forth. Where can I find a respected, most-authoritative reference (ideally on the level of W. Richard Stevens) for this small topic?

  • Encoding issue - 2nd band of ISO-8859-1 values do not get encoded?

    - by bstack
    Hello, I want to send the pound sign character i.e. '£' encoded as ISO-8859-1 across the wire. I perform this by doing the following: var _encoding = Encoding.GetEncoding("iso-8859-1"); var _requestContent = _encoding.GetBytes(requestContent); var _request = (HttpWebRequest)WebRequest.Create(target); _request.Headers[HttpRequestHeader.ContentEncoding] = _encoding.WebName; _request.Method = "POST"; _request.ContentType = "application/x-www-form-urlencoded; charset=iso-8859-1"; _request.ContentLength = _requestContent.Length; _requestStream = _request.GetRequestStream(); _requestStream.Write(_requestContent, 0, _requestContent.Length); _requestStream.Flush(); _requestStream.Close(); When I put a breakpoint at the target, I expect to receive the following: '%a3', however I receive '%u00a3' instead. ISO-8859-1 is divided into 2 groups of characters: (ref: http://en.wikipedia.org/wiki/ISO_8859-1) The lower range 20 to 7E - is where all characters seem to be encoded correctly The higher range A0 to FF - is where all characters seem to encode to their Unicode equivalent value As '£' is in higher range A0 to FF, it gets encoded to %u00a3. In fact when I use the first few characters of the higher range A0 to FF i.e. '¡¢£¤¥¦§¨©ª«¬®', I get '%u00a1%u00a2%u00a3%u00a4%u00a5%u00a6%u00a7%u00a8%u00a9%u00aa%u00ab%u00ac%u00ae'. This behaviour is consistent. The question I have is why do characters in the higher range A0 to FF get encoded to their unicode value - and not to their equivalent ISO-8859-1 value? Help would be greatly appreciated... Billy

  • Starting CLI application programmatically does not work depending on arguments

    - by Daniel Beck
    I try to start plink.exe (PuTTY Link, the command line utility/version of PuTTY) from a C# application to establish an SSH reverse tunnel, but it does no longer work as soon as I pass the correct parameters. What does that mean? The following works as expected: it opens a command line window, displays that I forgot to pass the password for the -pw argument quits, and shows the prompt. I know it got the arguments, since it specifically requests the one thing I did not provide. Uri uri = omitted; ProcessStartInfo info = new ProcessStartInfo(); info.FileName = "cmd"; info.Arguments = "/k \"C:\\Program Files (x86)\\PuTTY\\plink.exe\" -R 3389:" + uri.Host + ":" + uri.Port + " -N -l username -pw"; // TODO pwd Process p = Process.Start(info); I tried the same think with calling plink.exe directly instead of cmd.exe /k, but the window closes immediately, which is unfortunate for bug-hunting. BUT when I pass a password in the arguments, plink.exe displays the program help (showing available parameters) and quits: Uri uri = omitted; ProcessStartInfo info = new ProcessStartInfo(); info.FileName = "cmd"; info.Arguments = "/k \"C:\\Program Files (x86)\\PuTTY\\plink.exe\" -R 3389:" + uri.Host + ":" + uri.Port + " -N -l username -pw secretpassword"; Process p = Process.Start(info); No indication of missing parameters. Both the cmd /k and plink.exe variants do not work (the latter closes immediately, so no information regarding different behaviour). When I launch the application from the Windows 7 Start Menu launcher with the identical parameters, it opens a cmd.exe window and establishes the connection as requested. What's wrong? Is there a way plink.exe notices it's not running in a real shell? If yes, how can I circumvent it, like the Start Menu "prompt" does? I hope this question is right on SO, since it, though specifically for a single application, revolves around launching it successfully programmatically.

  • theoretical and practical matrix multiplication FLOP

    - by mjr
    I wrote traditional matrix multiplication in c++ and tried to measure and compare its theoretical and practical FLOP. As I know inner loop of MM has 2 operation therefore simple MM theoretical Flops is 2*n*n*n (2n^3) but in practice I get something like 4n^3 + number of operation which is 2 i.e. 6n^3 also if I just try to add up only one array a[i][j]++ practical flops then calculate like 3n^3 and not n^3 as you see again it is 2n^3 +1 operation and not 1 operation * n^3 . This is in case if I use 1D array in three nested loops as Matrix multiplication and compare flop, practical flop is the same (near) the theoretical flop and depend exactly as the number of operation in inner loop.I could not find the reason for this behaviour. what is the reason in both case? I know that theoretical flop is not the same as practical one because of some operations like load etc. system specification: Intel core2duo E4500 3700g memory L2 cache 2M x64 fedora 17 sample results: Matrix matrix multiplication 512*512 Real_time: 1.718368 Proc_time: 1.227672 Total flpops: 807,107,072 MFLOPS: 657.429016 Real_time: 3.608078 Proc_time: 3.042272 Total flpops: 807,024,448 MFLOPS: 265.270355 theoretical flop: 2*512*512*512=268,435,456 Practical flops= 6*512^3 =807,107,072 Using 1 dimensional array float d[size][size]:512 or any size for (int j = 0; j < size; ++j) { for (int k = 0; k < size; ++k) { d[k]=d[k]+e[k]+f[k]+g[k]+r; } } Real_time: 0.002288 Proc_time: 0.002260 Total flpops: 1,048,578 MFLOPS: 464.027161 theroretical flop: *4n^2=4*512^2=1,048,576* practical flop : 4n^2+overhead (other operation?)=1,048,578 3 loop version: Real_time: 1.282257 Proc_time: 1.155990 Total flpops: 536,872,000 MFLOPS: 464.426117 theoretical flop:4n^3 = 536,870,912 practical flop: *4n^3=4*512^3+overheads(other operation?)=536,872,000* thank you

  • Preloading Winforms

    - by msarchet
    I am currently working on a project where we have a couple very control heavy user controls that are being used inside a MDI Controller. This is a Line of Business app and it is very data driven. The problem that we were facing was the aforementioned controls would load very very slowly, we dipped our toes into the waters of multi-threading for the control loading but that was not a solution for a plethora of reasons. Our solution to increasing the performance of the controls ended up being to 'pre-load' the forms onto a hidden window, create a stack of the existing forms, and pop off of the stack as the user requested a form. Now the current issue that I'm seeing that will arise as we push this 'fix' out to our testers, and the ultimately our users is this: Currently the 'hidden' window that contains the preloaded forms is visible in task manager, and can be shut down thus causing all of the controls to be lost. Then you have to create them on the fly losing the performance increase. Secondly, when the user uses up the stack we lose the performance increase (current solution to this is discussed below). For the first problem, is there a way to hide this window from task manager, perhaps by creating a parent form that encapsulates both the main form for the program and the hidden form? Our current solution to the second problem is to have an inactivity timer that when it fires checks the stacks for the forms, and loads a new form onto the stack if it isn't full. However this still has the potential of causing a hang in the UI while it creates the forms. A possible solutions for this would be to put 'used' forms back onto the stack, but I feel like there may be a better way.

  • Make an image transparent in IE to show non-transparent background

    - by Select0r
    Hi, I'm trying to get this thing to work in IE (any version - works in FF, Opera, Safari, Chrome ...): I have a DIV with a background-image. The DIV also contains an image that should be transparent onMouseOver. The expected behaviour now is that the DIV-background would shine through the transparent image (which it does in all browsers but IE). Instead it looks like the image is getting transparent but on a white background, I can't see the DIV's background through the image. Here's some code: <div><a href="#" class"dragItem"><img /></a></div> And some CSS: .dojoDndItemOver { cursor : pointer; filter : alpha(opacity = 50); opacity : 0.5; -moz-opacity : 0.5; -khtml-opacity : 0.5; } .dragItem:hover { filter : alpha(opacity = 30); opacity : 0.3; -moz-opacity : 0.3; -khtml-opacity : 0.3; background : none; } All of this is embedded in a Dojo Drag-n-Drop-system, so dojoDndItemOver will automatically be set to the DIV on MouseOver, dragItem is set to the href around the image (using the same class on the image directly doesn't work at all as IE doesn't support "hover" on other items that href). Any ideas? Or is it an IE-speciality to just "simulate" transparency on images by somehow just greying them out instead of providing real transparency and showing whatever is beneath?

  • Right to Left UI in iPhone (Hebrew)

    - by Reflog
    Hello, I'm struggling in creating a RTL UI in iPhone application. The framework doesn't seem to have any support for RTL languages. The only thing is the alignment inside labels, which is nice, but it conflicts with other controls behaviour. The question is: Is there a working code for a RTL TableView? Something that would handle the disclosure buttons to be on the left, section titles to be right aligned, index view to be left aligned? As far as I understand I cannot move the index view of the tableview, i have to overlay some custom control... Any suggestions/pointers/examples? p.s. this is not a duplication of this question: http://stackoverflow.com/questions/1677988/right-to-left-alignment-for-uitableview since what I am looking for is a deeper customization, not just a new type of CellView. (Update: Mar 10) For now - I've removed support for indexView from the tableView at all, implemented the cells as custom views by myself (with disclosure buttons on the left), and customized the header/footer of the table as well. the only thing that is left is the Index View. Thanks in advance!

  • ASP.NET Applications Requests/Sec suddenly jumps to a value of about 70 million/sec. on 8 core web

    - by Subhrajit Roy
    We are doing performance testing of an ASP.NET web application with VSTS 2008. We start with 2000 users and slowly ramp up to 5000 users (reaches this user load at around 2.5 hours after the tests start, after this we stay at this user load). The total test duration is of about 6 hours During these runs we have found that the counter Requests/Sec (under category ASP.NET applications) suddenly spikes to a values of 36-72 millions !!!. This keeps on happening intermittently i.e we see this issue once in every 3 performance runs that we give on the same application. In our testing environment we have 4 web servers and interestingly enough we have found that this issue occurs only in the 8 core web servers. Summarizing ... Issue : The counter Requests/Sec (under category ASP.NET Applications) suddenly jumps to a value of about 70 million/sec. on 8 core web servers. This results in an increase in SQL server connections opened by the application. Response time goes for a toss. Error rates also show similar behaviour. However the counter ISAPI Extention Requests/sec does not show any abnormal increase. The graph of this counter almost overlaps with that of counter Requests/Sec till the time of the appearance of the spike.When the spike appears , this counter (ISAPI Extention Requests/sec) actually shows a drop. Test Settings : Performance test run with Visual Studio Team System 2008. Soak test run for 6 hours. Maximum user load 5000 users. This is load is attained at about 2.5 hours into the run and mainted for remaining duration.(i.e for around 3.5 more hrs) This issue is reproducible though happens intermittently. (i.e occurs one in three or four runs) Test Environment : Web site deployed on 4 Web Servers (Windows Server 2003). Of these 2 are 4 core machines and the remaining 2 are 8 core ones. .NET Framework 3.5 SP1 installed on all 4 web servers. Application hosted on IIS 6.0 run in Worker process isolation mode.

  • HTML - Correct way of coding a checkbox with a Label.

    - by egarcia
    I've been using formtastic in order to generate HTML forms on rails applications. My question, however, is really HTML-related. Today I found a strange behaviour on the way formtastic generates checkboxes (fields of type :boolean on formtastic lingo). The rest of the fields (non-checkboxes) are generated this way: <li> <label for="my_textbox_field">My TextBox</label> <input id="my_textbox_field" type="text" ... > </li> Checkboxes, however, are enclosed inside their <label> tags completely - like this: <li> <label for="my_boolean_field"> <input id="my_boolean_field" type="checkbox" ... > This is my boolean field </label> </li> Formtastic phylosophy seems to be based on the Learning to Love Forms presentation. In effect, on slide 36 of that presentation this structure is suggested for checkboxes. I guess in the presentation itself the presenter explained why this was done, but it is not written on the slides. Can anyone tell me why enclosing checkboxes inside their <label> tag might be a good idea, as opposed to putting them outside, like with textboxes?

  • Keyword to SQL search

    - by jdelator
    Use Case When a user goes to my website, they will be confronted with a search box much like SO. They can search for results using plan text. ".net questions", "closed questions", ".net and java", etc.. The search will function a bit different that SO, in that it will try to as much as possible of the schema of the database rather than a straight fulltext search. So ".net questions" will only search for .net questions as opposed to .net answers (probably not applicable to SO case, just an example here), "closed questions" will return questions that are closed, ".net and java" questions will return questions that relate to .net and java and nothing else. Problem I'm not too familiar with the words but I basically want to do a keyword to SQL driven search. I know the schema of the database and I also can datamine the database. I want to know any current approaches there that existing out already before I try to implement this. I guess this question is for what is a good design for the stated problem. Proposed My proposed solution so far looks something like this Clean the input. Just remove any special characters Parse the input into chunks of data. Break an input of "c# java" into c# and java Also handle the special cases like "'c# java' questions" into 'c# java' and "questions". Build a tree out of the input Bind the data into metadata. So convert stuff like closed questions and relate it to the isclosed column of a table. Convert the tree into a sql query. Thoughts/suggestions/links?

  • LINQ to SQL - Left Outer Join with multiple join conditions

    - by dan
    I have the following SQL which I am trying to translate to LINQ: SELECT f.value FROM period as p LEFT OUTER JOIN facts AS f ON p.id = f.periodid AND f.otherid = 17 WHERE p.companyid = 100 I have seen the typical implementation of the left outer join (ie. into x from y in x.DefaultIfEmpty() etc.) but am unsure how to introduce the other join condition ('AND f.otherid = 17') EDIT Why is the 'AND f.otherid = 17' condition part of the JOIN instead of in the WHERE clause? Because f may not exist for some rows and I still want these rows to be included. If the condition is applied in the WHERE clause, after the JOIN - then I don't get the behaviour I want. Unfortunately this: from p in context.Periods join f in context.Facts on p.id equals f.periodid into fg from fgi in fg.DefaultIfEmpty() where p.companyid == 100 && fgi.otherid == 17 select f.value seems to be equivalent to this: SELECT f.value FROM period as p LEFT OUTER JOIN facts AS f ON p.id = f.periodid WHERE p.companyid = 100 && AND f.otherid = 17 which is not quite what I'm after.

  • Problems playing multiple sounds using AVPlayer (NOT AVAudioPlayer)

    - by myetter37
    I'm trying to play a background song in my iPhone game and also have sound effects, using the AVFoundation framework and AVPlayerItem. I've scoured the Internet for help with AVPlayerItem and AVPlayer but I'm only finding stuff about AVAudioPlayer. The background song plays fine, but when the character jumps, I have 2 problems: 1) On the initial jump ([player play] inside jump method), the jump sound effect interrupts the background music. 2) If I try to jump again, the game crashes with the error "AVPlayerItem cannot be associated with more than one instance of AVPlayer" My professor told me to create a new instance of AVPlayer for each sound I want to play, so I'm confused. I'm doing data driven design, so my sound files are listed in a .txt and then loaded into a NSDictionary. Here's my code: - (void) storeSoundNamed:(NSString *) soundName withFileName:(NSString *) soundFileName { NSURL *assetURL = [[NSURL alloc] initFileURLWithPath:[[NSBundle mainBundle] pathForResource:soundName ofType:soundFileName]]; AVURLAsset *mAsset = [[AVURLAsset alloc] initWithURL:assetURL options:nil]; AVPlayerItem *mPlayerItem = [AVPlayerItem playerItemWithAsset:mAsset]; [soundDictionary setObject:mPlayerItem forKey:soundName]; NSLog(@"Sound added."); } - (void) playSound:(NSString *) soundName { // from .h: @property AVPlayer *mPlayer; // from .m: @synthesize mPlayer = _mPlayer; _mPlayer = [[AVPlayer alloc] initWithPlayerItem:[soundDictionary valueForKey:soundName]]; [_mPlayer play]; NSLog(@"Playing sound."); } If I move this line from the second method into the first: _mPlayer = [[AVPlayer alloc] initWithPlayerItem:[soundDictionary valueForKey:soundName]]; The game does not crash, and the background song will play perfectly, but the jump sound effect does not play, even though the console is showing "Playing sound." on each jump. Thank you

  • Alternative native api for Process.Start

    - by Akash Kava
    Ok this is not duplicate of "http://stackoverflow.com/questions/2065592/alternative-to-process-start" because my question is something different here. I need to run a process and wait till execution of process and get the output of console. There is way to set RedirectStandardOutput and RedirectStandardError to true, however this does not function well on some machines, (where .NET SDK is not installed), only .NET runtime is installed, now it works on some machines and doesnt work on some machines so we dont know where is the problem. I have following code, ProcessStartInfo info = new ProcessStartInfo("myapp.exe", cmd); info.CreateNoWindow = true; info.UseShellExecute = false; info.RedirectStandardError = true; info.RedirectStandardOutput = true; Process p = Process.Start(info); p.WaitForExit(); Trace.WriteLine(p.StandardOutput.ReadToEnd()); Trace.WriteLine(p.StandardError.ReadToEnd()); On some machines, this will hang forever on p.WaitForExit(), and one some machine it works correctly, the behaviour is so random and there is no clue. Now if I can get a real good workaround for this using pinvoke, I will be very happy.

  • Is android's motion event handling accurate??

    - by Peterdk
    Bug I have a weird bug in my piano app. Sometimes keys (and thus notes) hang. I did a lot of debugging and narrowed it down to what looks like androids inaccuracy of motion event handling: DEBUG/(2091): ACTION_DOWN A4 DEBUG/(2091): KeyDown: A4 DEBUG/(2091): ACTION_MOVE A4 => A4 DEBUG/(2091): ACTION_MOVE ignoring DEBUG/(2091): ACTION_MOVE A4 => A4 DEBUG/(2091): ACTION_MOVE ignoring DEBUG/(2091): ACTION_MOVE A4 => A4 DEBUG/(2091): ACTION_MOVE ignoring DEBUG/(2091): ACTION_UP B4 //HOW CAN THIS BE???? DEBUG/(2091): KeyUp: B4 DEBUG/(2091): Stream is null, can't stop DEBUG/(2091): Hanging Note: A4 X=240-287 EventX=292 Y=117-200 EventY=164 DEBUG/(2091): KeyUp Note: B4 X=288-335 EventX=292 Y=117-200 EventY=164 Clearly it can be seen here that out of nowhere I suddenly have an ACTION_UP for another note. Shouldn't I definitely get a ACTION_MOVE first? As shown in the end of the log, it's definitely not an error in region detection, since the ACTION_UP event is clearly in the B4 region. Logging Implementation details Every onTouchEvent() call is logged, so the log is accurate. The relevant pseudo-code for the ACTION_MOVE logging is: Key oldKey = Key.get(event.getHistoricalX(), event.getHistoricalY()); Key newKey = Key.get(event.getX(), event.getY()); Question Is this normal behaviour for Android (the jumping in coordinates)? Am I missing something?

  • WPF - expander Collapsed event being triggered by child controls with validation

    - by Shaboboo
    I have an expander that contains an ItemsControl. The items in the itemsControl are templated, some have textboxes in them, others have checkboxes. Both have bindings that cause validation. The styling and validation is working as expected. The problem is when I first expand the expander and cause a change to either control, the expander collapses again, this is not what I want. If I repeat this a second time this does not happen. I'm not sure what is triggering this strange behaviour. I've tried setting the focus to the itemsControl when the expander expands with no luck. What is differnt the second time it's expanded? Could it be the validation? Any Ideas? XAML: <Expander Header="{Binding SubSectionName}" Padding="0" > <ItemsControl ItemsSource="{Binding ConfigSubSectionSettings}" ItemTemplateSelector="{StaticResource Settings_Selector}" /> </Expander> <!-- Templates selected by the ItemTemplateSelector --> <DataTemplate x:Key="subSection_Bool"> <StackPanel Orientation="Horizontal"> <TextBlock x:Name="lbl" Text="{Binding SubSectionName}" > <CheckBox x:Name="chk" IsChecked="{Binding BoolValue, ValidatesOnDataErrors=True}" VerticalAlignment="Center" Margin="2" > </StackPanel > </DataTemplate> <DataTemplate x:Key="subSection_Text"> <StackPanel Orientation="Horizontal"> <TextBlock x:Name="lbl" Text="{Binding SubSectionName}" /> <TextBox x:Name="txt" VerticalAlignment="Center" Text="{Binding StringValue, ValidatesOnDataErrors=True}" /> </StackPanel> </DataTemplate>

  • How to effectively use WorkbookBeforeClose event correctly?

    - by Ahmad
    On a daily basis, a person needs to check that specific workbooks have been correctly updated with Bloomberg and Reuters market data ie. all data has pulled through and that the 'numbers look correct'. In the past, people were not checking the 'numbers' which led to inaccurate uploads to other systems etc. The idea is that 'something' needs to be developed to prevent the use from closing/saving the workbook unless he/she has checked that the updates are correct/accurate. The numbers look correct action is purely an intuitive exercise, thus will not be coded in any way. The simple solution was to prompt users prior to closing the specific workbook to verify that the data has been checked. Using VSTO SE for Excel 2007, an Add-in was created which hooks into the WorkbookBeforeClose event which is initialised in the add-in ThisAddIn_Startup private void wb_BeforeClose(Xl.Workbook wb, ref bool cancel) { //.... snip ... if (list.Contains(wb.Name)) { DailogResult result = MessageBox.Show("some message", "sometitle", MessageBoxButtons.YesNo); if (result != DialogResult.Yes) { cancel = true; // i think this prevents the whole application from closing } } } I have found the following ThisApplication.WorkbookBeforeSave vs ThisWorkbook.Application.WorkbookBeforeSave which recommends that one should use the ThisApplication.WorkbookBeforeClose event which I think is what I am doing since will span all files opened. The issue I have with the approach is that assuming that I have several files open, some of which are in my list, the event prevents Excel from closing all files sequentially. It now requires each file to be closed individually. Am I using the event correctly and is this effective & efficient use of the event? Should I use the Application level event or document level event? Is there a way to prevent the above behaviour? Any other suggestions are welcomed VS 2005 with VSTO SE

  • MSMQ on Win2008 R2 won’t receive messages from older clients

    - by Graffen
    Hi all I'm battling a really weird problem here. I have a Windows 2008 R2 server with Message Queueing installed. On another machine, running Windows 2003 is a service that is set up to send messages to a public queue on the 2008 server. However, messages never show up on the server. I've written a small console app that just sends a "Hello World" message to a test queue on the 2008 machine. Running this app on XP or 2003 results in absolutely nothing. However, when I try running the app on my Windows 7 machine, a message is delivered just fine. I've been through all sorts of security settings, disabled firewalls on all machines etc. The event log shows nothing of interest, and no exceptions are being thrown on the clients. Running a packet sniffer (WireShark) on the server reveals only a little. When trying to send a message from XP or 2003 I only see an ICMP error "Port Unreachable" on port 3527 (which I gather is an MQPing packet?). After that, silence. Wireshark shows a nice little stream of packets when I try from my Win7 client (as expected - messages get delivered just fine from Win7). I've enabled MSMQ End2End logging on the server, but only entries from the messages sent from my Win7 machine are appearing in the log. So somehow it seems that messages are being dropped silently somewhere along the route from XP or 2003 to my 2008 server. Does anyone have any clues as to what might be causing this mysterious behaviour? -- Jesper

  • Possible Data Execution Prevention problem in Windows 7

    - by Joel in Gö
    I have a serious problem with my .Net program. It calls a native dll, and then crashes instantly because it can't find a native method. This is behaviour we have seen before, whereby the C# compiler, in its infinite wisdom, sets the flag that the program is DEP compatible, even if it calls a native dll which patently is not. We have the standard workaround for this, where the flag is set to Not DEP Compatible in a post-build step, and this works fine. Everywhere except on my machine. I have Windows 7 32bit, and the program works fine on the Win 7 64bit machines that we have, as well as on Vista and XP; we have not yet been able to check on another Win7 32bit. However, on my machine the DataExecutionPolicy_SupportPolicy is 0, i.e. we have successfully switched DEP off. The dll in question also works fine when called from a native program. We are running out of ideas... any help would be much appreciated!

  • Snow Leopard & LSUIElement -> application not activating properly, window not "active" despite being

    - by Frank R.
    Hi, I'm running into a few problem with a background application that uses LSUIElement=1 to hide its dock item, menu bar and prevent it from appearing in the Command-Tab application switcher. It seems to be a Snow Leopard only problem. The application places an NSStatusItem in the menu bar and pops up a menu when clicked on. Selecting "Preferences..." should bring up an NSWindow with the preferences. The first thing that doesn't seem to work is that the Window does not get ordered in at the front, but appears behind all other application windows. I tried to fix this by calling [[NSApplication sharedApplication] activateIgnoringOtherApps: YES] but that didn't work. After a while I figured out that the menu is blocking the message to the run loop from being sent, so I wrote another method on the MainController and sent the message with a delay: [self performSelector:@selector(setFront:) withObject: [preferencesController window] afterDelay:1.0]; -(void)setFront: (id) theWindow { [[NSApplication sharedApplication]activateIgnoringOtherApps:YES]; [theWindow orderFrontRegardless]; [theWindow makeKeyWindow]; [[NSApplication sharedApplication] activateIgnoringOtherApps:YES]; } Note the send-every-possible-message-to-make-it-do-what-it-should-be-doing-approach. This works, kind-of, the window is brought to the front on top of all other windows from all apps, BUT most of the time it isn't active, meaning it's title bar is greyed out. Clicking on the title bar won't make the window active either. Clicking INSIDE of the window will make it active!? This all didn't seem to be a problem in Leopard; just calling activateIgnoringOtherApps and making the window key seemed to work just fine. In Snow Leopard there is a new API designed to replace LSUIElement that is supposed to emulate its behaviour: http://developer.apple.com/mac/library/releasenotes/cocoa/appkit.html I've played around with that, but it's SL-only and I haven't been able to get LSUIElement being set. Any help would be greatly appreciated!

  • IIS6 configuration for WCF/Silverlight

    - by Grayson Mitchell
    I am trying the simple senario of running a WCF service to return Active directory information on a user. (http://rouslan.com/2009/03/20-steps-to-get-together-windows-authentication-silverlight-and-wcf-service/) using Silverlight 4 & .net 4 However, I am being driven insane by trying to set this up in IIS. Currently I have my solution working in VS, but when I try to run the service in ISS a debug window tries to open... (and I can't get rid of it, is is complaining about the WCF call). <basicHttpBinding> <binding name="winAuthBasicHttpBinding"> <security mode="TransportCredentialOnly"> <transport clientCredentialType="Ntlm"/> </security> </binding> </basicHttpBinding> The Insanity: I have got the IIS to successfully call a WCF service (but can't reproduce), I have created 5 projects to try and get this working, but in my 5th I can't even browse the site (says it can't download silverlight application, but mime type are setup). My next step is to install Server2008 on a test machine and try IIS7... as all the various walkthrough's I have found just dont seem to work in IIS6.
