  • Is it good to use .settings for storing controls text data?

    - by Zenya
    In my WinForms applications I often put the controls text data (form title, labels texts, button captions, etc.) into a .settings (feature automatically generated by Visual Studio - based on the ApplicationSettingsBase class). In particular, Add a form or a control. In Solution Explorer add a new string item into the application scope of the settings file. Bind the control text property with the corresponding item of the settings file (through the property binding). Good point of this is that all my text data is collected in one place and easy to check and edit. Also it is convenient when I want to use the same text for several controls. However, I haven't heard that somebody uses the .settings such way. In tutorials for creating multilingual applications, for example, it is recommended to enter texts directly into the control property. So, is it good practice to use .settings for storing controls text data? Brief conclusion from the answers: Storing controls text data in the .settings is not common practice.

  • Client App with WCF to consume ASMX

    - by BDotA
    I have a webservice with .NET 1.1 (old school ASMX) and I am creating a client app to connect to it and use its services. From what I remember from the last time I had used Visual studio -which was 2003 version!- I can add a WebReference to it and easily use it. Tried it . it still works. but it looks like things have changed in 2008 and now we also have WCF. so I can add it as a Service Reference. but with this new method I could not find a way to create an Instance object to the ASMX service and call its methods... how do we accomplish the same thing with WCF?

  • Haxe app and Gtk-WARNING on linux servers

    - by Cambiata
    Hi! I'm trying a Haxe-compiled solution called FAR (Flash Archiver) created by Edwin Van Rijkom (http://code.google.com/p/vanrijkom-flashlibs/) wich uses a command-line tool for creating compressed archives. When running the FAR tool locally on my ubuntu laptop, everything works fine. When running remotely (terminal as Root) on my Ubuntu and Debian servers, it gives the following error: Gtk-WARNING **: cannot open display: I've tried to reach Edvin about this, but no response so far. Maybe it has something to do with installation or user rights on the server? Any clue?

  • Using a variable as identifier in a json array

    - by Robbert van den Bogerd
    Hi folks! I'm wondering if it is possible to use assigned variables as identifier in a json array. When I tried this, I was getting some unexpected results: (Code is simplified, parameters are passed in a different way) var parameter = 'animal'; var value = 'pony'; Util.urlAppendParameters (url, {parameter : value}); Util.urlAppendParameters = function(url, parameters) { for (var x in parameters) { alert(x); } } Now the alert popup says: 'parameter' instead of 'animal'. I know I could use a different method (creating an array and assigning every parameter on a new line), but I want to keep my code compact. So my question is: Is it possible to use a variable as an identifier in the json array, and if so, could you please tell me how? Thanks in advance!

  • Java: using endpoint to publish webservice to tomcat server

    - by Will
    hi all, i am creating a simple SOAP web service. i am to ensure that it runs on a tomcat web service. im trying to implement this with JAX-WS (see code) my question is: does the Endpoint.publish use the tomcat server to host this or is it a mini glassfish kind of server? should i be extending UnicastRemoveObject or something similiar instead? ideally it would be able to be packaged into a .WAR and dropped in the directory and just work. It doesn't seem to work with my installed tomcat server as is because it says the port is already in use. I'm using Ubuntu karmic with the tomcat6 package installed, it could also be my user doesnt have permissions to publish to the running tomcat on 8080 i hope this question is clear enough sample code: @WebService public class UserAttributes { public static void main(String[] args) { UserAttributes instance = new UserAttributes(); Endpoint.publish("http://localhost:8082/WebServices/userattributes", instance); } public string Hello() { return "Hello World"; } }

  • Depth First Search Basics

    - by cam
    I'm trying to improve my current algorithm for the 8 Queens problem, and this is the first time I'm really dealing with algorithm design/algorithms. I want to implement a depth-first search combined with a permutation of the different Y values described here: http://en.wikipedia.org/wiki/Eight_queens_puzzle#The_eight_queens_puzzle_as_an_exercise_in_algorithm_design I've implemented the permutation part to solve the problem, but I'm having a little trouble wrapping my mind around the depth-first search. It is described as a way of traversing a tree/graph, but does it generate the tree graph? It seems the only way that this method would be more efficient only if the depth-first search generates the tree structure to be traversed, by implementing some logic to only generate certain parts of the tree. So essentially, I would have to create an algorithm that generated a pruned tree of lexigraphic permutations. I know how to implement the pruning logic, but I'm just not sure how to tie it in with the permutation generator since I've been using next_permutation. Is there any resources that could help me with the basics of depth first searches or creating lexigraphic permutations in tree form?

  • Strategies for Error Handling in .NET Web Services

    - by Jarrod
    I have a fairly substantial library of web services built in .NET that I use as a data model for our company web sites. In most .NET applications I use the Global ASAX file for profiling, logging, and creating bug reports for all exceptions thrown by the application. Global ASAX isn't available for web services so I'm curious as to what other strategies people have come up with to work around this limitation. Currently I just do something along these lines: <WebMethod()> _ Public Function MyServiceMethod(ByVal code As Integer) As String Try Return processCode(code) Catch ex As Exception CustomExHandler(ex) 'call a custom function every time to log exceptions Return errorObject End Try End Function Anybody have a better way of doing things besides calling a function inside the Catch?

  • maximum string length quota error consuming WCF webservice from Biztalk.

    - by TygerKrash
    I'm getting this error message "The Maximum string content length quota (8192) has been exceeded while reading XML data. This quotea may be increased by changing the MaxStringContentLength property on the XmlDictionaryReaderQuotas object used when creating the XML reader" In the one of my orchestrations that consumes a wcf webservice (stacktrace indicates the receive shape is where the issue is), It is likely that the response is very large. looking at some of the other questions with this error message the solution is to change a WCF bindings setting in the configuration file. However I can't find these configuration settings when I'm using biztalk. They don't seem to be generated anywhere, should I be trying to add them to BTSNTSVc.exe.config. Any suggestions welcome.

  • Integration Testing an Entire *Existing* Application (w/ automatic execution of test suite)

    - by Ev
    Hi there, I have just joined a team working on an existing Java web app. I have been tasked with creating an automated integration test suite that should run when developers commit to our continuous integration server (TeamCity), which automatically deploys to our staging server - so really the tests will be run against our staging web app server. I have read a lot of stuff about automated integration testing with frameworks like Watir, Selenium and RWebSpec. I have created tests in all of these and while I prefer Watir, I am open to anything. The thing that hasn't become clear to me is how to create an entire test suite for an application, and how to have that suite execute in it's entirety upon execution of some script. I can happily create individual tests of varying complexity, but there is a gap in my knowledge about how to tie everything together into something useful. Does anyone have any advice on how to create a full test suite and have it execute automatically? Thanks!

  • Self updating application install with WIX?

    - by Brian ONeil
    I am writing an application that needs to be installed on a large number of desktops and also needs to update itself. We are looking at WIX for creating the installation. I have used ClickOnce and it is not a good solution for this install. WIX seems to fit, but there is no good process for auto update that I have found. I have looked at ClickThrough, but it doesn't seem ready for prime time yet. Does anyone have another good solution to use with WIX (or maybe another install program) to auto update an application install?

  • Shutting Down SSH Tunnel in Paramiko Programatically

    - by PlaidFan
    We are attempting to use the paramiko module for creating SSH tunnels on demand to arbitrary servers for purposes of querying remote databases. We attempted to use the forward.py demo that ships with paramiko but the big limitation is there does not seem to be an easy way to close an SSH tunnel and the SSH connection once the socket server is started up. The limitation we have is that we cannot activate this from a shell and then kill the shell manually to stop the listner. We need to open the SSH connection, tunnel, perform some actions through the tunnel, close the tunnel, and close the SSH connection within python. I've seen references to a server.shutdown() method but it isn't clear how to implement it correctly. Any help would be greatly appreciated...

  • What's the official Microsoft way to track counts of dynamic controls to be reconstructed upon Postback?

    - by John K
    When creating dynamic controls based on a data source of arbitrary and changing size, what is the official way to track exactly how many controls need to be rebuilt into the page's control collection after a Postback operation (i.e. on the server side during the ASP.NET page event lifecycle) specifically the point at which dynamic controls are supposed to be rebuilt? Where is the arity stored for retrieval and reconstruction usage? By "official" I mean the Microsoft way of doing it. There exist hacks like Session storage, etc but I want to know the bonafide or at least Microsoft-recommended way. I've been unable to find a documentation page stating this information. Usually code samples work with a set of dynamic controls of known numbers. It's as if doing otherwise would be tougher. Update: I'm not inquiring about user controls or static expression of declarative controls, but instead about dynamically injecting controls completely from code-behind, whether they be mine, 3rd-party or built-in ASP.NET controls.

  • Using Application Settings and reading defaults from app.config

    - by Peter Goras
    Hi, I need to deploy a Windows Forms application using ClickOnce deployment. (VS2008, .NET 3.5) And I need to provide a configuration file for this app that any user can modify. For this reason, I am using Application Settings instead of standard appSetttings in app.config so I can separate the the user config from app config. see http://msdn.microsoft.com/en-us/library/ms228995(VS.80).aspx Creating a Settings.settings file using VS generated a class with hard-coded default values like this: [global::System.Configuration.DefaultSettingValueAttribute("blahblah")] public string MyProperty ... WTF? I want to read the default values from the app.config! So I created my own class deriving from ApplicationSettingsBase but I cannot get this to read values from the app.config. Any ideas?

  • Looking for an elegant way to store one-to-many relationship in coredata when order is important

    - by Eric Schweichler
    I've been trying to come up with a way to solve my problem, but every solution I can think of is messy and makes me want to retch. I have a one-to-many relationship, consisting of a Team object that can have many Member objects. When I built my data model using Xcode, I was given the default NSSet in which to store the member objects, Unfortunately Sets are not ordered and I need to preserve the order of the Member objects and I need to know if there are empty spaces between Members. I thought of Using an NSArray in place of the NSSet and creating a dummy Member object in my data store that I could use to mark vacant a spot between to Member objects, but that solution really feels like too much of a hack to me. Since I'll always have to filter out this dummy Member from any queries. An NSDictionary would be perfect as I could store the Member object references and their positions as Object-Key pairs, (taking care of both order and vacancies) but apparently CoreData does not support NSDictionary. Has anyone had a similar need, and devised a simple solution?

  • How to limit choice field options based on another choice field in django admin

    - by umnik700
    I have the following models: class Category(models.Model): name = models.CharField(max_length=40) class Item(models.Model): name = models.CharField(max_length=40) category = models.ForeignKey(Category) class Demo(models.Model): name = models.CharField(max_length=40) category = models.ForeignKey(Category) item = models.ForeignKey(Item) In the admin interface when creating a new Demo, after user picks category from the dropdown, I would like to limit the number of choices in the "items" drop-down. If user selects another category then the item choices should update accordingly. I would like to limit item choices right on the client, before it even hits the form validation on the server. This is for usability, because the list of items could be 1000+ being able to narrow it down by category would help to make it more manageable. Is there a "django-way" of doing it or is custom JavaScript the only option here?

  • How can I populate highchart jQuery plugin dynamically from MVC action?

    - by Anders Svensson
    I'm trying out the Highcharts jQuery plugin for creating charts of data in an MVC application. But I need to get the data for the function dynamically from an Action Method. How can I do that? Taking the example from the Highcharts site (http://highcharts.com/documentation/how-to-use): var chart1; // globally available $(document).ready(function() { chart1 = new Highcharts.Chart({ chart: { renderTo: 'chart-container-1', defaultSeriesType: 'bar' }, title: { text: 'Fruit Consumption' }, xAxis: { categories: ['Apples', 'Bananas', 'Oranges'] }, yAxis: { title: { text: 'Fruit eaten' } }, series: [{ name: 'Jane', data: [1, 0, 4] }, { name: 'John', data: [5, 7, 3] }] }); }); How can I get the data in there dynamically from the action method? Someone suggested I might use JSon, but couldn't specify how. If this is the case, I would really appreciate a simple and specific example, because I don't know much about JSon. Any help appreciated!

  • php, mySQL - how to create a table?

    - by user296516
    Hi guys, I have written a code that should check weather there is a table called imei.$addimei and, if not, create it... $userdatabase = mysqli_connect('localhost', 'root', 'marina', 'imei'); ... $result = mysqli_query($userdatabase, "SELECT * FROM imei".$addimei."" ); if ( !$result ) { echo('creating table...'); /// if no such table, make one! mysql_query ( $userdatabase, 'CREATE TABLE imei'.$addimei.'( ID int NOT NULL AUTO_INCREMENT, PRIMARY KEY(ID), EVENT varchar(15), TIME varchar(25), FLD1 varchar(35), FLD2 varchar(35), IP varchar(25), )' ); } Yet the CREATE TABLE somehow doesn't seem to work. Warning: mysql_query() expects parameter 1 to be string, object given in C:\xampp\xampp\htdocs\mobi\mainmenu.php on line 564 Any idea's what wrong? Thanks!

  • Object reference error even when object is not null

    - by Shrewd Demon
    hi, i have an application wherein i have incorporate a "Remember Me" feature for the login screen. I do this by creating a cookie when the user logs in for the first time, so next time when the user visits the site i get the cookie and load the user information. i have written the code for loading user information in a common class in the App_Code folder...and all my pages inherit from this class. code for loading the user info is as follows: public static void LoadUserDetails(string emailId) { UsersEnt currentUser = UsersBL.LoadUserInfo(emailId); if (currentUser != null) HttpContext.Current.Session["CurrentUser"] = currentUser; } Now the problem is i get an "Object reference" error when i try to store the currentUser object in the session variable (even though the currentUser object is not null). However the password property in the currentUser object is null. Am i getting the error because of this...or is there some other reason?? thank you

  • WCF extensions without including the assembly version

    - by Marc Gravell
    As discussed here, I'm trying to add a WCF endpoint-extension; I've got it working, but I need to include the full assembly details: <extensions> <behaviorExtensions> <add name="protobuf" type="ProtoBuf.ServiceModel.ProtoBehaviorExtension, protobuf-net, Version=1.0.0.275, Culture=neutral, PublicKeyToken=257b51d87d2e4d67"/> </behaviorExtensions> </extensions> What I would like to do (to avoid issues when updating etc, especially for samples) is to include just the names: <add name="protobuf" type="ProtoBuf.ServiceModel.ProtoBehaviorExtension, protobuf-net"/> (which is what you might expect from standard assembly-naming conventions) However, if I do this, I get a big error: Parser Error Message: An error occurred creating the configuration section handler for system.serviceModel/behaviors: Extension element 'protobuf' cannot be added to this element. Verify that the extension is registered in the extension collection at system.serviceModel/extensions/behaviorExtensions. Is it possible (and if so: how) to add an extension without having to specify the assembly-version?

  • Office Interop addins installer?

    - by jimbojw
    I have three C# Solutions in Visual Stuido 2008, one each for Word, Excel and PowerPoint using interop to hook various events. In each Solution, I have exactly one class, the one created by default when using File - New - Project - Visual C# - Office - 2007. Now that I have my addins working properly, it's time to create an installer. I understand that I may also have to distribute the PIAs. I would like my installer to register itself such that it can be uninstalled via the normal Add/Remove Programs mechanism. My organization is somewhat standardized around WiX for creating installers, but I'm open to any suggestions. How do I produce an MSI or EXE capable of installing my addins? GUI/wizard for the installer is not necessary. I'm happy to RTFM - so far all the tutorials I've found only explain how to create the project and do some of the coding. Maybe I'm using the wrong search terms? Thanks in advance for any help!

  • Will SQL Server Partitioning increase performance without changing filegroups

    - by Tom
    Scenario I have a 10 million row table. I partition it into 10 partitions, which results in 1 million rows per partition but I do not do anything else (like move the partitions to different file groups or spindles) Will I see a performance increase? Is this in effect like creating 10 smaller tables? If I have queries that perform key lookups or scans, will the performance increase as if they were operating against a much smaller table? I'm trying to understand how partitioning is different from just having a well indexed table, and where it can be used to improve performance. Would a better scenario be to move the old data (using partition switching) out of the primary table to a read only archive table? Is having a table with a 1 million row partition and a 9 million row partition analagous (performance wise) to moving the 9 million rows to another table and leaving only 1 million rows in the original table?

  • Would this hack for per-object permissions in django work?

    - by Edward
    According to the documentation, a class can have the meta option permissions, described as such: Options.permissions Extra permissions to enter into the permissions table when creating this object. Add, delete and change permissions are automatically created for each object that has admin set. This example specifies an extra permission, can_deliver_pizzas: permissions = (("can_deliver_pizzas", "Can deliver pizzas"),) This is a list or tuple of 2-tuples in the format (permission_code, human_readable_permission_name). Would it be possible to define permissions at run time by: permissions = (("can_access_%s" % self.pk, / "Has access to object %s of type %s" % (self.pk,self.__name__)),) ?

  • BackgroundWorker and WebBrowser Control

    - by James Jeffery
    Is it possible/recommended to use background worker threads with the web browser control? I am creating a bot that searches google for keywords, then checks for sites in the first 10 pages to see if a site is ranked. The user can provide a maximum of 20 sites to check, and can use proxies. So ideally I'd like to have 5 threads working at once. Is it possible? I might have heard somewhere that there are problems with WebBrowser control and threads.

  • Tools for code snippet execution

    - by nzpcmad
    By "code snippet execution", I mean the ability to write a few lines of code, run and test it without having to fire up an IDE and create a dummy project. It's incredibly useful for helping people with a small code sample without creating a project, compiling everything cleanly, sending them the code snippet and deleting the project. I'm not asking about the best code snippets or a snippet editor or where to store snippets! For C#, I use Snippet Compiler. For Java, I use Eclipse Scrapbook. For LINQ, I use LINQPad. Any suggestions for other (better?) tools? e.g. is there one for Java that doesn't involve firing up Eclipse? What about C?
