• Disabling FileSystemWatcher for specific updates?

  - by chaiguy

  Does anyone have any ideas how I can reliably disable a FileSystemWatcher object when my application makes changes to the files in the directory, so that I am only watching for external changes to the directory? I've tried setting EnableRaisingEvents to false immediately before performing a write and setting it back to true immediately after, but it seems this method is not reliable, and occasionally I still get the event firing. The only other thing I can think of is to wait a small amount of time after performing the write to let the OS finish up the modification of the directory before re-enabling the FSW, but that seems hackish and I don't like it. To add to the problem, the directory consists of potentially many files, the identities of which are beyond my knowledge and control, so I can't just wait for the event to fire for a specific file and then ignore it. There could be any number of FSW events firing after a single modification (because of the potentially many files getting updated).

• I Clean Solution'd my Winform App and now it's broken...

  - by Refracted Paladin

  I have a Winform App that uses a 3rd Party Library of Controls, DevExpress. I also created a bunch of Controls myself, extending those controls. Everything has been working fine when all of a sudden I opened VS today and on the Design Page all my extended controls were missing. I then tried rebuilding to no avail. Then I tried Cleaning and Rebuilding and made it even worse. Now I have tons(520) of erros stating things like -- Error 179 The name 'datBirthDate' does not exist in the current context D:\Documents\Visual Studio 2008\Projects\MatrixReloaded\MatrixReloaded\Controls\Member\ucGeneral.cs 339 17 MatrixReloaded also if I try to open a form or user control in Design Mode I first get this -- could not find type, "MyType" please make sure that the assembly that contains this type is referenced and then, if I click Ignore and Continue I get this for all Forms and Contros when I try and look at them in Design Mode -- Exception of type System.OutOfMemoryException was thrown Help!?!? When I googled I came across mostly references to VS 2003...I am on 2008 sp1.

• TabItems from View collection

  - by byte

  I am using MVVM. I have a tab control. I will have a collection of items. I want to display each of this item in the collection as a tab item. The view in each tab item is different and may have its own viewmodel. How do I achieve this? E.g. I have 3 items in the collection. The Tab item template contains an ItemControl. I would like to now have 3 Tabs created and the ItemControls inside each tabitem may be showing different views. One way I could do is have a single view and viewmodel for each item. Now based on some condition the View will display different UI elements and behave differently. But I am afraide this will make the view quite complex over a period of time.

• Reload external javascript after asynchronous postback via UpdatePanel

  - by Protector one

  I have an external javascript on my page, e.g. something like: <script src="http://foo.com/script.js" type="text/javascript"></script> and an UpdatePanel somewhere. The script writes some content, and does this from within an anonymous javascript function in the js file. I.e., there is something like this in the script: (function(){document.write('content');})(); Whenever the UpdatePanel is updated through asynchronous postback, everything the script did (or any javascript on my page, for that matter) is made undone. For normal javascript, I would just use: Sys.WebForms.PageRequestManager.getInstance().add_endRequest(myFunction) to redo all that, but since the function in the script source file is anonymous and called upon definition, I'm SOL! Any ideas? Note: the external js source is from another domain and its content is out of my control.

• Cross Theaded Calls - Many controls Heavy GUI Application after .net 1.1 2.0 upgrade- best way ??

  - by keepsmilinyaar

  I have recently upgraded a .net1.1 solution to .net2.0. AS this is a very heavy GUI appilcation with loads of controls and many multithreaded operations that update the GUI. While these operations worked seamlessly in .net1.1 it is throwing up Cross Threaded Illegal operations after the upgrade. Considering the fact that tehre are numerous grids, buttons and status labels that need to be updated via these multi threaded operations, I decided to code for checking the InvokeRequired solution, however doing that for every control would probably not be the best way to go about it. I was wondering if you could suggest a better way of how I can go about it or propose any OOPS based class structure that I could code around to make the code look better. Please do let me know if my question is unclear. Thanks in advance

• Testing Java Classes with JMeter

  - by Martin Dürrmeier

  I'd like to test a Java Service Call. My first attempt was to use the "Java Request Sampler" The docu says This sampler lets you control a java class that implements the JavaSamplerClient interface. I'm not sure how to get the org.apache.jmeter.protocol.java.sampler.JavaSamplerClient Interface as there is no Maven Artifact nor provided binaries on the JMeter side. Just a JMeter Maven Plugin (which is not what I'm looking for). I could install the needed binaries in my local Maven Repository, I Just don't know where they are available. Wondering if anybody at all is using the "Java Request Sampler" ? P.S. Maybe I should try the JUnit Sampler

• Cross-platform GUI toolkits with WPF-style composition capabilities

  - by Alexey Romanov

  A huge advantage of WPF over, say, WinForms is its composability. To quote Programming WPF: One level up, WPF provides its “content model,” which allows any control to host any group of other controls. You don’t have to build special BitmapButton or IconComboBox classes; you put as many images, shapes, videos, 3D models, or whatever into a Button (or a ComboBox, ListBox, etc.) as suit your fancy. Are there any cross-platform GUI frameworks (preferably with Java bindings) out there which also let you do this?

• SWT Composite consructor throws IllegalArgumentException on a non-null argument

  - by Alexey Romanov

  This piece of code (in Scala) val contents = { assert(mainWindow.detailsPane != null) new Composite(mainWindow.detailsPane, SWT.NONE) } throws an exception: Exception occurred java.lang.IllegalArgumentException: Argument not valid at org.eclipse.swt.SWT.error(Unknown Source) at org.eclipse.swt.SWT.error(Unknown Source) at org.eclipse.swt.SWT.error(Unknown Source) at org.eclipse.swt.widgets.Widget.error(Unknown Source) at org.eclipse.swt.widgets.Widget.checkParent(Unknown Source) at org.eclipse.swt.widgets.Widget.<init>(Unknown Source) at org.eclipse.swt.widgets.Control.<init>(Unknown Source) at org.eclipse.swt.widgets.Scrollable.<init>(Unknown Source) at org.eclipse.swt.widgets.Composite.<init>(Unknown Source) at main.scala.NodeViewPresenter$NodeViewImpl.<init>(NodeViewPresenter.scala:41) According to the documentation, IllegalArgumentException should only be thrown when the parent is null, but I am checking for that. detailsPane is a CTabFolder. Can anybody say why this could happen?

• Loop background images using jQuery

  - by da5id

  I'm trying to get the back-ground image of a legacy div (by which I mean it already has a background image, which I cannot control & thus have to initially over-write) to smoothly rotate indefinitely. Here's what I have so far: var images = [ "/images/home/19041085158.jpg", "/images/home/19041085513.jpg", "/images/home/19041085612.jpg" ]; var counter = 0; setInterval(function() { $(".home_banner").css('backgroundImage', 'url("'+images[counter]+'")'); counter ++; if (counter == colours.length) { counter = 0; } }, 2000); Trouble is, it's not smooth (I'm aiming for something like the innerfade plugin), and it's not indefinite (it only runs once through the array). All help greatfully appreciated :)

• How can I use a config-file in Expression Blend 4?

  - by sofri

  Hi, while trying to use the "InfoStrat"-Bing-Maps-Control in Expression Blend 4 for my Surface Application, I get the error message: "Mixed mode assembly is built against version v2.0.50527 of the runtime and cannot be loaded in the 4.0 runtime without additional configuration information" I already found out that I need to write this configfile: <configuration> <startup useLegacyV2RuntimeActivationPolicy="true"> <supportedRuntime version="v4.0"/> </startup> </configuration> But Expression Blend doesn't seem to recognize that it is there. So how can I solve this problem?

• Play Video on Safari iTouch

  - by dave cohen

  I have a web site that opens iframe for video on page, page uses ajax to pull in videos from selected menu. As expected and understood, on iTouch after selecting video it shows a play button, which brings up video in another screen. However, when the video completes, it returns browser to page prior to one where video was played from. Sequence: - open Page1 - go to Page2 which offers videos to play, in iframe - play video - video completes, returns to Page1, not Page2!! Only happens on iTouch, so must be issue with how control is returned on video completion. Any suggestions? If this is not a known problem, I can work up example (currently, need account on site). Thanks Dave

• Java's ThreadPoolExecutor equivalent for C#?

  - by chillitom

  Hi Guys, I used to make good use of Java's ThreadPoolExecutor class and have yet to find a good equivalent in C#. I know of ThreadPool.QueueUserWorkItem which is useful in many cases but no good if you want to control the number of threads assigned to a task or have multiple individual queues for different task types. For example I liked to use a ThreadPoolExecutor with a single thread to guarantee sequential execution of asynchronous calls.. Is there an easy way to do this in C#? Is there a non-static thread pool implementation? Thanks, T.

• Why would the first call to a KVC setter have an NSTextField instance as the argument?

  - by Stephen

  If I have a NSTextField bound through an NSObjectController to a model object, I would expect the setter of the model object to be called with an NSString as the argument, but instead, I receive the instance of the control that I am bound too the first time I am called. - (NSString *)property { NSLog(@"returning property"); return property; } - (void)setProperty:(NSString *)string { NSLog(@"recieved %@", string) } - (id) init { if (self = [super init]) { property = [[NSString alloc] initWithString:@"value"]; } NSLog(@"property is %@",property"); return self; } (The program doesn't run if you try anything in setProperty, because it tries to send NSString messages to string - which might be an NSTextField.) Console Output: 2010-05-12 14:19:14.096 Trouble[13108:10b] property is enter value 2010-05-12 14:19:14.100 Trouble[13108:10b] recieved <NSTextField: 0x1025210> 2010-05-12 14:19:14.106 Trouble[13108:10b] returning property

• How a servlet can get the absolute path to a file outside of the servlet?

  - by WolfmanDragon

  We have been using System.getProperties("user.dir") to get the location of a properties file. Now that it has been deployed on Tomcat(via servlet), the System call is giving the location as tomcat and not at the location at where the properties file exist. How can we call the the properties file dynamically? Given: Tomcat is not the only way the app will be deployed We have no control on where the app may be placed. Relative paths will not work as that Vista is being used and Vista breaks relative paths. This must work on all OS, including(but not limited to) Linux, XP and Vista. EDIT I implied this, but in case I was not clear enough, I have no way of knowing the path String.

• E.cancel loop in Visual basic

  - by Ahmed

  I am making an server control application ( simple with some buttons to start/stop the server ) And when the user wants to close the application there will be prompted an confirm box. Private Sub Form1_FormClosing(sender As Object, e As FormClosingEventArgs) Handles Me.FormClosing Dim response As Integer response = MsgBox("Are you sure you want to stop the server", vbYesNo, "Stop Server ?") If response = vbYes Then Shell("cscript ""stop.vbs""", 1) Close() Else e.Cancel = True End If End Sub That is the code I have now. But when I start the application and close it with the X button or with "Close Window" I will be prompted with the question until I click on no, then it will close. It's a loop and it stops when you first click on yes then on no. Can someone help me with solving this ?

• How to pass an event to a method and then subscribe to it?

  - by Ryan Peschel

  Event Handler public void DeliverEvent(object sender, EventArgs e) { } #1: This Works public void StartListening(Button source) { source.Click += DeliverEvent; } #2: And so does this.. public void StartListening(EventHandler eventHandler) { eventHandler += DeliverEvent; } But in #2, you cannot call the method because if you try something like this: StartListening(button.Click); You get this error: The event 'System.Windows.Forms.Control.Click' can only appear on the left hand side of += or -= Is there any way around that error? I want to be able to pass the event and not the object housing the event to the StartListening method.

• Handling Data Hierarchies in code

  - by Miau

  Hi there So, say I have a string to parse with a given format that maps to a tree like data structure. The string is kinda similar to a folder path, and the structure is similar to a file structure, except its got some rules so for something@cat1@otherSomething you would get /something/cat1/otherSomething for something@cat2@otherSomething you would get /something/cat2/otherSomething other examples /OtherThing/cat1/otherSomething/Blah /OtherThing/cat4/otherSomething Where something, cat1, otherSomethign, etc are some sort of instances of ICategory There are certain rules that control what subcategories are valid and which subcategories are not acceptable, at the moment I m considering a heavy Object hierachy, but I know this is not a flexible solution, I d prefer the categories to be a bit more general but again, since there are rules about what can go next I m not sure how to do this. An example of a rule can be: OtherThing can only have subcategories cat1 and cat4 ( anything else is invalid) An option would be to use some sort of convention based aproach to instantiate a particular class given a subsection of the string(like cat4) but it seems a bit too complex, I m all ears Thanks

• Is there a cleaner way to Bind property to owner's DataContext?

  - by Dan Bryant

  I have some code that looks like this: <Expander Header="{Binding SelectedSlot.Name}" Visibility="{Binding ShowGroupSlot, Converter={StaticResource BooleanToVisibility}}"> <Controls:GroupPrototypeSlotControl Slot="{Binding DataContext.SelectedSlot, RelativeSource={RelativeSource Mode=FindAncestor, AncestorType={x:Type Expander}}}" /> </Expander> This works, but the ugliness of the Slot Binding bothers me. This is required because the GroupPrototypeSlotControl has a GroupPrototypeViewModel as its DataContext. If I simply use {Binding SelectedSlot}, it attempts to resolve it on the 'child' ViewModel, which fails. I get around this by explicitly looking at the DataContext of my parent control. Is there a cleaner way to do this type of binding?

• Silverlight - rebinding to a property?

  - by bplus

  Hello, I'm just getting started with silverlight. Basically I have a silverlight user control that has various dataGrids and a combobox, their item sources set to the properties of a custom plain c# object. My problem is that I have a dropdown list that when a user selects an item from the list a new row should appear in one of the grids. All I'm doing is handling the SelectionChanged event and adding a new item to to a list in my custom object and setting the itemsource for the grid again. This doesnt seem to work; no row is added to the dataGrid I have no idea how to force my grid to "rebind" to this property. I've been reading about dependency properties, are these what I need? Any pointers would be really appreciated.

• ASP.Net: Scheduled tasks in a shared environment.

  - by UpTheCreek

  This is really an extension of this question, which asked the best way to schedule tasks which need to be performed periodically within ASP.NET in a normal environment. However, I would like to ask this specifically for a Shared Hosting Environment (most of the answers to the previous question would not work in a shared environment as far as I know). One obvious solution would be to have a page which is responsible to performing the tasks on the hosted machine, and call this page from another machine (that you have full control over) using e.g. a windows scheduled task. This is a bit nasty though - are there any better approaches?
