• Building Visual studio like application, need inputs..

  - by akjoshi

  Hi, I am working on a Visual studio like application i.e. hava a tolbox, an editor and property grid similar to VS. ser can drag and drop the controls(custom and third party) to the editor window and perform operations like resize, move, align, group etc.; Properties of that control needs to be displayed in property grid and user can update them from there. As per my current understanding I will have to extend the Canvas to create my own editor and and Interface for controls which it supports; Each supported control will have to implemnt this interface so that it can be placed in our editor. Something similar to this - http://www.codeproject.com/KB/WPF/WPFDiagramDesigner_Part4.aspx Looking forward for any kind of help, comment or links.

• Re-Apply currency formatting to a UITextField on a change event

  - by Jim Aldes

  Howdy all, I'm working with a UITextField that holds a localized currency value. I've seen lots of posts on how to work with this, but my question is: how do I re-apply currency formatting to the UITextField after every key press? I know that I can set up and use a currency formatter with: NSNumberFormatter *currencyFormatter = [[NSNumberFormatter alloc] init]; [currencyFormatter setNumberStyle:NSNumberFormatterCurrencyStyle]; ... [currencyFormatter stringFromNumber:...]; but I don't know how to hook it up. For instance, if the value in the field reads "$12,345" and the user taps the "6" key, then the value should change to "$123,456". Which callback is the "correct" one to do this in (should I use textField:shouldChangeCharactersInRange:replacementString: or a custom target-action) and how do I use the NSNumberFormatter to parse and re-apply formatting to the UITextField's text property? Any help would be much appreciated! Thanks!

• Better Alternative to Case Statement

  - by Kyle Rozendo

  Hi All, I currently have a switch statement that runs around 300 odd lines. I know this is not as giant as it can get, but I'm sure there's a better way to handle this. The switch statement takes an Enum that is used to determine certain properties that pertain to logging. Right now the problem sets in that it is very easy to leave out an enumeration value and that it will not be given a value as it is not in the switch statement. Is there an option one can use to ensure that every enumeration is used and given a custom set of values it needs to do its job? Thanks, Kyle

• Listening and firing events with Javascript and maybe jQuery

  - by at

  In my Javascript and Flex applications, users often perform actions that I want other Javascript code on the page to listen for. For example, if someone adds a friend. I want my Javascript app to then call something like triggerEvent("addedFriend", name);. Then any other code that was listening for the "addedFriend" event will get called along with the name. Is there a built-in Javascript mechanism for handling events? I'm ok with using jQuery for this too and I know jQuery makes extensive use of events. But with jQuery, it seems that its event mechanism is all based around elements. As I understand, you have to tie a custom event to an element. I guess I can do that to a dummy element, but my need has nothing to do with DOM elements on a webpage. Should I just implement this event mechanism myself?

• LLBLGEN: Linq to LLBGEN don't work

  - by StreamT

  I want to make custom select from the database table using Linq. We use LLBGEN as ORM solution. I can't do LINQ query to Entities Collection Class unless I call GetMulti(null) method of it. Is it possible to do LINQ query to LLBGEN without extracting all table first? BatchCollection batches = new BatchCollection(); BatchEntity batch = batches.AsQueryable() .Where(i => i.RegisterID == 3) .FirstOrDefault(); // Exception: Sequence don't contains any elements batches = new BatchCollection(); batches.GetMulti(null); // I don't want to extract the whole table. BatchEntity batch = batches.AsQueryable() .Where(i => i.RegisterID == 3) .FirstOrDefault(); //Works fine

• Change Casing in WCF Service Reference

  - by Eric J.

  I'm creating a service reference to a web service written in Java. The generated classes now follow the Java casing convention used in the web service, for example class names are camelCase rather than PascalCase. Is there a way to get the desired casing from the service reference? CLARIFICATION: With WSE based services, one could modify the generated Reference.cs to provide .NET standard casing and use XmlElementAttribute to map to the Java naming presented by the external web service, like this: [System.Xml.Serialization.XmlElementAttribute("resultType", Form=System.Xml.Schema.XmlSchemaForm.Unqualified)] [System.Runtime.Serialization.DataMember] public virtual MyResultType ResultType { ... } Not terribly maintenance-friendly without writing custom code to either generate the proxy code or modify it after it's been generated. What I'm after is one or more options to present a WCF generated client proxy to calling applications using the .NET casing conventions, achieving the same as I did previously with WSE. Hopefully with less manual effort.

• Pagination For SMS in Android specifically

  - by Priyank

  Hi. I had a pagination related question posted earlier. Here I went through the posted answers and suggested choices and I realized that to implement pagination in an application I could still write db level queries and ensure that I could implement pagination, even if in a crude form. However I have few follow up questions now: I am trying to show SMS from a content provider. Suppose I don't want to use content provider; can I access SMS table in database through my application. Aoes android's security framework allow that? How do people generally handle pagination problems in android, related to content that they are not storing but instead are fetching through content providers. (Android's own or custom) Isn't this a bigger problem. I am surprised to find so little text online about it.

• iphone OCMockObject and unit-testing a class that inherits from NSURLConnection

  - by Justin Galzic

  I want to unit test the custom init method of a class that inherits from NSURLConnection -- how would I do this if the init of my testable class invokes NSURLConnection's initWithRequest? I'm using OCMock and normally, I can mock objects that are contained within my test class. For this inheritance scenario, what's the best approach to do this? - (void)testInit { id urlRequest = [OCMockObject mockForClass:[NSURLRequest class]]; MyURLConnectionWrapper *conn = [[MyURLConnectionWrapper alloc] initWithRequest:urlRequest delegate:self someData:extraneousData]; } My class is implemented like this: @interface MyURLConnectionWrapper : NSURLConnection { } - (id)initWithRequest:(NSURLRequest *)request delegate:(id)delegate someData:(NSString *)fooData @end @implementation MyURLConnectionWrapper - (id)initWithRequest:(NSURLRequest *)request delegate:(id)delegate someData:(NSString *)fooData { if (self = [super initWithRequest:request delegate:delegate]) { // do some additional work here } return self; } Here's the error I get: OCMockObject[NSURLRequest]: unexpected method invoked: _CFURLRequest

• Scrambling URLS for dynamic data

  - by ggonsalv

  What is the best method to obfuscate the urls created in Dynamic Data? eg \Products\List.aspx?ProductId=2 could become \Products\List.aspx?x=UHJvZHVjdElkPTI= where "ProductId=2" is base 64 encoded to prevent casual snooping on \Products\List.aspx?ProductId=3 \Products\List.aspx?ProductId=4 etc...? I will probably have to inherit from an existing object and override some function The question is which object and what function GetActionPath of the Metamodel object seems interesting, but how does the DynamicRoute "{table}/{Action}.aspx" play in into it... Right now on Asp.net 1.1 site I use an custom implementation of the following code. http://www.mvps.org/emorcillo/en/code/aspnet/qse.shtml It is HTTPModule that uses regular expression to rewrite all the querystrings and also with reflection changes the Querystring collection with decoded values. So where is the hook to affect the change.

• In a distributed environment, how can I configure log4j to log to different files for each JVM insta

  - by Renan Mozone

  My application runs on IBM WebSphere 6.1 Network Deployment. The application have several JSP files and Java classes. Today each host have only one JVM instance but my intention is to start another instance on each host. How can I configure log4j to log to different files for each JVM instance in the same host? I thought of using variable substitution on log4j XML configuration file but it only works with system properties. So, it is safe and recommended to set a custom system property just to store the JVM name? Anyone knows another strategy to achieve this in a 'elegant' way?

• What should I use for the filepath if I'm developing from my desktop?

  - by codeninja

  I'm having an extremely difficulty time getting the flowplayer to show up and the worst part is I have no idea what is wrong because I'm not getting any error messages! I have an external javascript file: C:/desktop/mysite/js/jq/plugins.js calling $f() from: C:/desktop/mysite/thirdparty/flowplayer/flowplayer.js the swf files also live there... I'm working on file/desktop (no localhost or webserver) $(video.id).flowplayer("thirdparty/flowplayer/flowplayer-3.1.15.swf", { clip:{ .... }, // min Flash version version:[9,115], // older versions will see a custom message onFail:function(){ alert("Failed!"); }, onError:function(errCode,errMsg){ alert(errCode+errMsg); } }); I don't know what path to use for the SWFs to get them to load, is the path relative to the javascript (plugins.js) that calls $f() or is it relative to the path of the flowplayer.js ?? bangs head on wall

• Adjust a Control Template and still respect the Theme of the OS?

  - by bitbonk

  In WPF how do I modifiy the template for a standard control in a way that it will respect the current Theme of the Operating System later on? If I just "edit a copy" of the template in blend, it will just give me the template of the currently running theme. Is this correct? So when I apply the modified template and run the app on different themes it will always look the same. For custom controls and even for data templates the problem is similar. How do I provide a template that respects all possible themes of the OS?

• Huge EAR deployment

  - by bozo

  Hello all, I'm trying to figure out how to deploy a huge (40-50 MB) EAR file to the server through a rather slow VPN connection. The EAR contains EJB and WAR projects created in Glassfish, and 90% of the file size is from external dependency libraries used. Has anyone came up with a strategy for elegant deployment to production system from Netbeans, where the deployment (over the network) is done only for what is really needed (i.e. just one WAR, not the entire EAR, or just one lib, not the entire libraries subproject). Related to the first point, how to separate external dependency libs from project in Netbeans, so that the project compiles on development machine, but when the EAR/WAR/EJB is created it does not contain all the dependency JARs, which are making it huge. Perhaps we need to write custom ant script? Start using maven? Thank you all for kind answers, Bozo

• Keep an object for the time the connection is running in ASP.NET

  - by vtortola

  Hi, I'm developing a web service with ASP.NET, is not an .asmx or WCF, it's a custom one, so I'm working with the Http classes (context, request, response, etc..). Session is disabled. I'm working with my own handler and module. I'd like to keep a object alive and accessible for the time the connection is alive. I mean, a request enters, I assign a DbCommand to it and that connection will use that command as long is doing things, when that connection is ended, the object should be disposed. I've thought, that I can add it to my IPrincipal implementation, then when the connection is authenticated in the module and the user retrieved, I can add that DbCommand to the IPrincipal, so I can retrieve it from wherever I want in the code, and after in the module EndRequest event, I can dispose it, but I don't know if there is a better approach to do this. What do you think? cheers

• Using info.plist for storing target-specific values for a multi-target app

  - by andybee

  I have a multi-target iPhone app which currently includes a header file with constant definitions that are conditionally included at build time depending on which target is being built. However, I was wondering if it might be better to instead include this information in the info.plist for the build, as this generally holds target-specific meta, so logically seems more appropriate. Therefore, my questions are: Is it acceptable to include custom (non-Apple defined) keys in the info.plist file? Is this a suitable place to include meta for the app which changes between targets?

• MembershipProvider user id

  - by niao

  Greetings, I wrote a custom MembershipProvider for my asp.net mvc application. I get the user as follows: public override MembershipUser GetUser(string username, bool userIsOnline) { using (CPersistanceManager pm = new CPersistanceManager()) { pm.EnsureConnectionOpen(); MembershipUser membershipUser = null; COperator oper = pm.OperatorRepository.Get(username); membershipUser = new MembershipUser(ApplicationName, oper.Username, oper.ROWGUID, oper.Email, string.Empty, string.Empty, oper.IsActive, false, DateTime.Today, DateTime.Today, DateTime.Today, DateTime.Today, DateTime.Today ); return membershipUser; } } how can I then retrieve logged user id (rowguid) in any controller?

• UITableView resizing rows problem

  - by Vin

  Hi All, Hope to get solution to this problem. I have been stuck on it since a long time now. I have a a tableView which has custom labels drawn upon the cell using CGRect. I receive the data from a web service in arrays. Initially i display a line of data on the cells. When the user selects a cell, I call reloadsRowAtIndexPath to increase the height of selected row. In the process, cellForRowAtIndexPath gets called again. I keep track of this by a flag, and when cellForRowAtIndexPath gets called again, I display the two more lines of data from arrays, on the cell. What i am getting is all overlapping data on one other. I tried to remove already placed labels in didSelectRowAtIndexPath, but to no avail. Please help me on this Thanks in advance.

• netsh http add urlacl problem

  - by BadCat914

  I'm trying to set up some ports from a WIX installer. For WinXP we use httpcfg in a custom action and this works fine. For Win7, we're trying: netsh http add urlacl url=http://127.0.0.1/8346/ user="NT AUTHORITY\Authenticated Users" sddl="D:(A;;GX;;;AU)" The WIX installer correctly executes this statement and sets up the ports - FOR THE ADMINISTRATOR who runs the .msi. Users with lesser priviliges cannot access these ports. I need to set it up for all users on the machine, but I've tried about everything I can think of with no luck. Something I find odd is that the Admin user can see the assigned ports using netstat -a, but they do not appear at all using netsh http show urlacl...is that an indicator of something wrong?

• PLT Scheme Extracting field ids from structures

  - by Steve Knight

  I want to see if I can map PLT Scheme structure fields to columns in a DB. I've figured out how to extract accessor functions from structures in PLT scheme using the fourth return value of: (struct-type-info) However the returned procedure indexes into the struct using an integer. Is there some way that I can find out what the field names were at point of definition? Looking at the documentation it seems like this information is "forgotten" after the structure is defined and exists only via the generated-accessor functions: (<id>-<field-id> s). So I can think of two possible solutions: Search the namespace symbols for ones that start with my struct name (yuk); Define a custom define-struct macro that captures the ordered sequence of field-names inside some hash that is keyed by struct name (eek).

• jQuery-ui problem with modal dialog from ajax

  - by Intra

  Hi I have following setup index.html with <div id="container"</div using anchor method I load different html content into this container. My content contains div for modal dialog "dialog-form" and I initialise it with the custom function from the javascript included in index.html on successful ajax load using callback $.get("callback.php",query, function(data){ $("#container").html(data); initPos(); // here we run javascript to initialise modal dialog }); Everything is ok until user click other menu (we load different content) and after that again clicks menu with this modal dialog, so page loads again, we call script again (everything is ok yet), dialog opens, information from the dialog is submitted to server and on sucessful sumbit I want to close the dialog with ('#dialog-form').dialog('close');it worked first time, but no longer works because we initialised this dialog twice and using Firebug I can see two different instances of modal dialog with the same name. So, what is the right way to do the thing? Is there any way to close multiple dialogs with the same name or maybe we can kill all closed modal dialogs when user clicks different menu?

• SQL Server replication - how to sync tables from internal database to read-only website database

  - by frankadelic

  I have an internal SQL Server 2005 database "ADMIN_DATA" that is used by admin users. We would like to sync three of the database tables in ADMIN_DATA out to another SQL Server 2005 database "WEB_DATA", which is used by a public web app. WEB_DATA is read-only - only SELECT statements are allowed, while ADMIN_DATA is updated all the time. What is the best solution? How can this be accomplished with minimal custom coding and/or changes to database tables? Notes: ADMIN_DATA and WEB_DATA are different physical machines and on different subnets. The syncing operation doesn't need to be instantaneous.

• Looking for a good example usage of get_or _create in Django views and raising a Form error

  - by Rik Wade

  I am looking for a good example of how to achieve the following: I would like to use get_or_create to check whether an object already exists in my database. If it does not, then it will be created. If it does exist, then I will not create the new object, but need to raise a form error to inform the user that they need to enter different data (for example, a different username). The view contains: p, created = Person.objects.get_or_create( email = registration_form.cleaned_data['email'], defaults = { 'creationDate': datetime.datetime.now(), 'dateOfBirth': datetime.date(1970,1,1) }) So 'p' will contain the existing Person if it exists, or the new Person if not. I would like to act on the boolean value in 'created' in order to skip over saving the Person and re-display the registration_form and raise an appropriate form validation error. The alternative I'm considering is doing a check in a custom Form validation method to see whether a Person exists with the data in the provided 'email' field, and just raising a validation error.

• Alternative to udev functionality on OSX

  - by S1syphus

  I'm trying to create a custom file/check in check out script for external hardrives, however part of the script is from a Linux machine, which I have tested works fine, but uses udevinfo, OS X doesn't have udev, so is there anything that offers the same functionality? #!/bin/bash declare -a EXTERNAL_DISKS declare -a INTERNAL_DISKS for disk in /dev/[sh]d[a-z]; do eval `udevinfo -q env -n $disk` [ "$ID_BUS" = "usb" ] && EXTERNAL_DISKS=( ${EXTERNAL_DISKS[@]} $disk ) [ "$ID_BUS" = "scsi" ] && INTERNAL_DISKS=( ${INTERNAL_DISKS[@]} $disk ) done echo "Internal disks: ${INTERNAL_DISKS[@]}" echo "External disks: ${EXTERNAL_DISKS[@]}" Anybody know any alternatives? Or a way this could be accomplished on OSX using bash?

• Account preferences crashes on ListPreference
