• WPF DataGrid adding extra "ghost" row

  - by hs2d

  Hei, In my application i'm using DataGrid to show some data. To get everything working with threading i'm using AsyncObservableCollection as DataContext of DataGrid. When my application starts it looks for files in some folders and updates AsyncObservableCollection. Now here's where things go bad, when i start the application for some reason i get 2 rows with same data in DataGrid even if there is one item in collection. If i add a delay(Thread.Sleep() 50ms minimum) before executing loading files method then DataGrid show everything correctly (no extra row). Have anybody encountered something similar or is there something else i should try? Thanks in advance!

• jQuery autocomplete works with a local string but not when the same String is called off the server

  - by Ankur

  This is related to the question I asked at http://stackoverflow.com/questions/2802948/how-to-make-an-ajax-call-immediately-on-document-loading My code is: $(document).ready(function(){ $.ajax({ type: "GET", url: "../AutoComplete", success: function(data) { var dataArray = data; alert(dataArray); $("#example").autocomplete(dataArray); } }); }); The value that is printed in the alert is: "Manuscript|Text|Information Object|Basketball|Ball|Sporting Equipment|Tarantula|Spider|Australian Spider|Cricket Player|Medieval Artefact|Person|Sportsperson|Leonardo Da Vinci|Country|Language|Inventor|Priest|Electronics Manufacturer|Object|letter|Artefact|governance model|Organism|Animal".split("|"); If instead I do this: $(document).ready(function(){ $.ajax({ type: "GET", url: "../AutoComplete", success: function(data) { var dataArray = "Manuscript|Text|Information Object|Basketball|Ball|Sporting Equipment|Tarantula|Spider|Australian Spider|Cricket Player|Medieval Artefact|Person|Sportsperson|Leonardo Da Vinci|Country|Language|Inventor|Priest|Electronics Manufacturer|Object|letter|Artefact|governance model|Organism|Animal".split("|"); alert(dataArray); $("#example").autocomplete(dataArray); } }); }); It works fine?

• How to best deal with photos passed to IFilter?

  - by sharptooth

  I'm implementing an IFilter for indexing image formats. One problem is photos - many users have tons of photos, photos are huge and loading and searching for text on them is time consuming. Yes, sometimes people use cameras instead of scanners for digitizing documents, but the potential problems IMO far outweight the possibility of encountering a document digitized with a photo camera. So my implementation will not extract text from photos at all. What should the IFilter do once it detects that a given file is a photo image - indicate an error or return empty text?

• How to implement arrays in an interpreter?

  - by Ray

  I have managed to write several interpreters including Tokenizing Parsing, including more complicated expressions such as ((x+y)*z)/2 Building bytecode from syntax trees Actual bytecode execution What I didn't manage: Implementation of dictionaries/lists/arrays. I always got stuck with getting multiple values into one variable. My value structure (used for all values passed around, including variables) looks like this, for example: class Value { public: ValueType type; int integerValue; string stringValue; } Works fine with integers and strings, but how could I implement arrays? (From now on with array I mean arrays in my experimental language, not in C++) How can I fit the array concept into the Value class above? Is it possible? How should I make arrays able to be passed around just as you could pass around integers and strings in my language, using the class above? Accessing array elements or memory allocation wouldn't be the problem, I just don't know how to store them.

• How to block the UI during asynchronous operations in WPF

  - by mcintyre321

  We have a WPF app (actually a VSTO WPF app). On certain controls there are multiple elements which, when clicked, load data from a web service and update the UI. Right now, we carry out these web requests synchronously, blocking the UI thread until the response comes back. This prevents the user clicking around the app while the data is loading, potentially putting it into an invalid state to handle the data when it is returned. Of course the app becomes unresponsive if the request takes a long time. Ideally, we'd like to have the cancel button active during this time, but nothing else. Is there a clever way of doing this, or will we have to switch the requests to execute asynchronously using backgroundworker and write something that disables all the controls apart from the cancel button while a request is in progress?

• How to make a legacy webapp spring aware at the container level for bean autowire into Servlets?

  - by Pete

  We have a legacy web application (not Spring based) and are looking for best practices to autowire some newer Spring configured (thread safe) service beans into instance variables in several of the legacy servlets. Rewriting every servlet to Spring MVC is out of scope. For testability, we do not want any Spring specific bean lookup code in the Servlets to look up beans by name or similar. Note that we are not concerned about web specific bean scopes such as session or request; all services are singleton scope. Below shows relevant code snippet MyServlet extends LegacyServletSuperclass { private MyThreadSafeServiceBean wantThisToBeAutowiredBySpring; .... }

• Disable animation when moving CALayers

  - by Sean Clark Hess

  The following code animates the movement, even though I didn't use beginAnimations:context. How do I get it to move without animating? This is a new iphone view project, and these are the only updates to it. // Implement viewDidLoad to do additional setup after loading the view, typically from a nib. - (void)viewDidLoad { [super viewDidLoad]; sublayer = [CALayer new]; sublayer.backgroundColor = [[UIColor redColor] CGColor]; sublayer.frame = CGRectMake(0, 0, 100, 100); [self.view.layer addSublayer:sublayer]; } - (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event { sublayer.position = [[touches anyObject] locationInView:self.view]; }

• Immutable Dot Net strings

  - by klork

  I usually define my string variables in vb.net as Dim f_sName as string=String.Empty f_sName = "foo" Given the immutable nature of strings in .net, is there a better way to initialize strings and deal with the "Variable 'f_sName ' is used before it has been assigned a value. A null reference exception could result at runtime." warning? Also for classes that do not have constructors which accept no arguments such as System.Net.Sockets.NetworkStream, what is the best way to define and initialize a variable of that type? All comments are highly appreciated. Thanks

• In Prism (CAL), how can I RegisterPresenterWithRegion instead of RegisterViewWithRegion

  - by Edward Tanguay

  I have a module in a Prism application and in its initialize method I want to register a presenter instead of a view with a region, i.e. I want to do this: PSEUDO-CODE: regionManager.RegisterPresenterWithRegion( "MainRegion", typeof(Presenters.EditCustomerPresenter)); instead of loading a view like this: regionManager.RegisterViewWithRegion( "MainRegion", typeof(Views.EditCustomerView)); The presenter would of course bring along its own view and ultimately register this view in the region, but it would allow me to bind the presenter to the view in the presenter's constructor instead of binding the two together in XAML (which is more of a decoupled MVVM pattern which I want to avoid here). How can I add a Presenter to a Region instead of a view? namespace Client.Modules.CustomerModule { [Module(ModuleName = "CustomerModule")] public class CustomerModule : IModule { private readonly IRegionManager regionManager; public CustomerModule(IRegionManager regionManager) { this.regionManager = regionManager; } public void Initialize() { regionManager.RegisterViewWithRegion("MainRegion", typeof(Views.EditCustomerView)); } } }

• String concatenation produces incorrect output in Python?

  - by Brian

  I have this code: filenames=["file1","FILE2","file3","fiLe4"] def alignfilenames(): #build a string that can be used to add labels to the R variables. #format goal: suffixes=c(".fileA",".fileB") filestring='suffixes=c(".' for filename in filenames: filestring=filestring+str(filename)+'",".' print filestring[:-3] #now delete the extra characters filestring=filestring[-1:-4] filestring=filestring+')' print "New String" print str(filestring) alignfilenames() I'm trying to get the string variable to look like this format: suffixes=c(".fileA",".fileB".....) but adding on the final parenthesis is not working. When I run this code as is, I get: suffixes=c(".file1",".FILE2",".file3",".fiLe4" New String ) Any idea what's going on or how to fix it?

• C# - Hiding ListViewItem based on a filter

  - by fonix232

  I want to hide some items based on a text filter in a ListView. Basically the listview loads the items from a text file, and I don't want it to be read and/or written when the user searches the list. The search is done in a combobox's KeyDown event, but there is no "Visible" property of the ListViewItem. Is there any easy way to do this, WITHOUT re-reading the file? (as it is an XML file, and it could even contain thousands of items, it would be hard to search efficiently and even let the user use the application, as the search would take for minutes (mostly with the loading)).

• Java: How do you access a sub-object of an object with no "getXXX" method to that sub-object

  - by Daxon

  I'll explain with pictures from Eclipse Debugger I have an Class called "FieldContext", (I can't edit it, it's compiled in the Java OVal API) Within "FieldContext" on the eclipse variable tab are "CompileTimeType" and "field" Q1 Is there a legend for the icons in the variables tab? like what the red box with the "F" means + yellow diamond boxes? Now I want to access the fields inside the "field" object (RedBox) .. preferably "name" But the "FieldContext" does not have a "getField()" method, yet it has a "getCompileTimeType()" method. Q2 So is there anyway to get that field object being a "SerializableField" Class from the "FieldContext"? If eclipse debugger can see/get/edit them then I hope I can do the same in Java.

• "autotest/rails [...] doesn't [...] exist. Aborting"

  - by Ethan

  I'm finding that autotest has stopped working... $ autotest loading autotest/rails Autotest style autotest/rails doesn't seem to exist. Aborting. According to this blog post, the common reason for this error is that people don't have the autotest-rails gem installed. However, I definitely have that installed: autotest-rails (4.1.0) ZenTest (4.1.4, 4.1.3, 4.1.1, 4.0.0, 3.11.1, 3.11.0, 3.10.0, 3.9.3, 3.9.2) I haven't installed any new gems today or yesterday, though I might have done a gem update yesterday. Another issue I saw mentioned was incompatibility with Ruby 1.9, but I'm using MRI Ruby 1.8.6.

• How can I use my multiple cored dedicated server to run my java application?

  - by Delta

  I have a game built in a java environment and I use JVM. I have 4 cores @ 2.4Ghz and my server is only using one of those cores... I've tried and searched and I still have no guides to setup multiple cores to run the game like, say 1 core for running the character saving + loading, and 1 core for the server itself, and 1 core for a helper to help other cores that need more power. I don't even know if this is possible but this is all in java the operating machine is windows server 2003 and I've tried so hard I just don't know what to do. May someone please help me! Thank you so much!

• show definition (browse) in *.pdb of *.dll file

  - by ala

  I have built a Library project (DLL) in .NET. And sometimes I use the DLL along with its PDB file as a reference in some other projects. Now in the new project, I cant browse through the code of the DLL to debug. I can only see the definitions of class/methods/variables. That's by using "show definition" by browsing through the "class view" However, only in case of an exception I the contents of the DLL opens and I could see the entire code of the DLL from the new project. How could I see the contents (code) of the DLL before an exception occur?

• Generating an array of functions?

  - by Wordpressor

  I have a few PHP files filled with multiple functions. Let's call them functions1.php, functions2.php, functions3.php: function function_something( $atts ) { extract( something_atts( array( 'foo' => 'bar', 'bar' => 'foo, ), $atts ) ); return 'something'; } I'm loading these files within all_functions.php like this: require_once('functions1.php'); require_once('functions2.php'); require_once('functions3.php'); I'm wondering if it's possible to create an array of all these functions and their attributes? I'm thinking about something like: function my_functions() { require_once('functions1.php'); require_once('functions2.php'); require_once('functions3.php'); } And then some foreach loop, but I'm not sure how should it look like after all. I know this probably looks tricky, but I'm just curious if I'm able to list all my WordPress shortcodes without PHP's Reflection API :)

• When are reference files(dlls) loaded?

  - by Daniel

  I wrote a program that makes a reference to Microsoft.Web.Administration.dll, which is not present on Windows Server 2003. The program checks for the os and does not reference the dll if the os is 2003. if(OSVersion == WindowsServer2003) //do the job without referencing the Microsoft.Web.Administration.<br> else if(OSVersion == WindowsServer2008) //reference the Microsoft.Web.Administration.dll file.<br> When I tested this program on Windows Server 2003, an error occured telling me it couldn't locate the Microsoft.Web.Administration.dll. But when I separated the if-else block into 2 different methods as below, and the error did not occur. if(OSVersion == WindowsServer2003) //do the job without referencing the Microsoft.Web.Administration.<br> else if(OSVersion == WindowsServer2008) //DoIt2008Style(); So I wanted to know about reference file loading time in more detail. could you point me to some resources?

• reading 2 lines from IniFile

  - by Lakkerw

  Trying again. On advice, adding the piece of code that I do understand. I am fine with the fact that I have to save 4 bits of information in two lines like so: IniFile.WriteString('TestSection','Name','Country'); IniFile.WriteString('TestSection','City','Street'); My question is more about loading this information back into the form. If in my IniFile I have saved for example the following code [TestSection] John=Uk London=barlystreet Mike=Spain Madrid=eduardostrata Emma=USA New York=1st Avenue Made up information in the IniFile. Added through the code above. Now my question is: How could I load for example, when I type in an edit box Mike, the rest of the belonging information.(Spain, Madrid,eduardostrata).

• How to Practically Split Values from CSV File into MySQL Database

  - by Ryan

  Let's suppose I have the following line in a CSV file (I removed the header row in this example): "500,000",2,50,2,90000 I have a PHP script read the CSV file, break the file into individual lines, and store each line in an array called $linearray. Then, I use a foreach loop to look at each line individually. Within the foreach loop, I break the line into separate variables using the following function: $line = str_replace("'","\'",$line); From here, I insert the values into separate columns within a MySQL database. The script works. The values are inserted into a database, but I run into a problem. I want: "500,000" | 2 | 50 | 2 | 90000 But I get this: "500 | 000" | 2 | 50 | 2 | 90000 The script isn't smart enough to understand it should skip commas within quotation marks. Do you know how I can alter my script to make sure I get the output I'm looking for? Thanks.

• Assigning a MVC Controller property from Asp.Net page

  - by JasonMHirst

  I don't know if I've understanding MVC correctly if my question makes no sense, but I'm trying to understand the following: I have some code on a controller that returns JSON data. The JSON data is populated based on a choice from a dropdown box on an Asp.Net page. I thought (incorrectly) that Session variables would be shared between the Asp.Net project and the MVC Project. What I'd like to do therefore (if this is possible), is to call a Sub on the MVC that sets a variable before the JSON query is run. I have the following: Sub SetCountryID(ByVal CountryID As Integer) Me.pCountrySelectedID = CountryID End Sub Which I can call by the following: Response.Write("http://localhost:7970/Home/SetCountryID/?CountryID=44") But this then results in a blank page - again obviouslly totally incorrect! Am I going about MVC the wrong way or do I still have a hell of a lot more learning to do? Is this even possible to do?

• Determine if a day of week and time fall in a custom weekend period

  - by Y Low

  I've been trying to come up with a method, that given a day of week and time of day, it will return if it falls under a custom weekend period. The weekend period is saved in 4 variables as follows: The day of week when it starts (0-6) The time of day when it starts (0-23) The day of week when it ends (0-6) The time of day when it ends (0-23) Based on these fields, the weekend period can be anything the user selected (even if it is well beyond a regular weekend) I've been banging this one for awhile but to no avail. I'm trying this in delphi but any language will do, as I'm looking for the algorithm and not the implementation.

• Get pointer to member function from within member function in C++

  - by Eli

  Currently in the program I am attempting to write I need to be able to get a pointer to a member function within a member function of the same class. The pointer needs to be passed to a function as a void (*)(). Example: //CallFunc takes a void (*)() argument class testClass { public: void aFunc2; void aFunc1; } void testClass:aFunc2(){ callFunc(this.*aFunc1); // How should this be done? } void testClass:aFunc1(){ int someVariable = 1; } I'm trying to do this in GCC 4.0.1. Also, the member function being called can't be static because it references non-static variables in the class that it is part of.

• How to partially update views in an app widget without rebuilding all the RemoteViews

  - by Gianni Costanzi

  I'm implementing an app widget and I'd like to be able to change the property of a single view in the widget layout, without rebuilding all the RemoteViews from scratch, which involves loading XML etc and which is not necessary in some circumstances.. Is there a way to say "update property X on view identified by a specific ID in the current widget layout"? I've seen that there is a partiallyUpdateAppWidget method in the AppWidgetManager class but I can't understand nor if it is meant for this purpose neither how it must be used.. Can you help me or point me to a useful link or example?

• Garbage collection - manually wiping EVERYTHING!

  - by Glycerine

  I have been building a game for a while (nearly done) - But the game needs a replay button and its a big task. I know the GC is dreadful in flash, but I wanted to know if there is a way to wipe EVERYTHING as if the flash app has just begun. Clearing memory, game data - I haven't to worry about game loading as its not really heavy on data. Everything pretty much lives in a DataModel - but I fear if I just clear the all variables, I'll have pockets of orphaned memory. Any forwarding idea would be great. cheers guys.
