• FxCop CA2000 Warning in UserControls

  - by esjr

  Running FxCop on a WebProject that contains a UserControl will result in a CA2000 Warning (Call System.IDisposable.Dispose on object) for every ServerControl (Label, TextBox,...) in that UserControl. I understand why this would happen. Replacing the 'offending' ServerControls with a PlaceHolder and then adding the Controls in code (Using...End Using) might be a way around that, but it is not always an option.But, if they are not 'kosher' why have ServerControls you can drop in your ascx/aspx in the first place ?Am I missing something ? If, like in my case, you inherit a sizeable collection of fairly complex UserControls, do I now add every 'offending' Control to the GlobalSupperssions file (that's a lot of mind numbing right-clicking) ?I do not want to suppress all CA2000 warnings since it makes perfect sense to fix them, but not in the case of ServerControls in UserControls.

• Drupal 6 - Including a module form in a view

  - by espais

  I'm making use of the Favorites module, in order to allow my users to favorite nodes they like. Currently, I know that there is a block available for listing out the favorites, along with the 'Add to favorites' button at the top of this list. What I'd like to do is generate the form which includes the button, and include it within each node that I generate. I'd gotten it hacked up and quickly working by copying the generated form and placing it in my views-view--fields-.tpl.php template, however I believe that doing it this way goes against the thought behind Drupal, and probably introduces security issues with the form_id and form_token being hand-written. I've attempted to call the get_form function, and have passed it the form_id that I found in the generated form code, however I can't get Drupal to recognize it. From some Googling I've noticed that generating module forms programmatically may require a hook, but I haven't been able to find any good examples of this. What is the best way to go about creating this form?

• Unable to use Client Application Services with custom MembershipProvider.

  - by Shimmy

  Hi, I have a Windows-Forms Application that I configured to use with an ASP.NET Service that is an Authentication service using a custom MembershipProvider. When I call Membership.CreateUser in the Windows Application a NotSupportedException is thrown telling: "Specified method is not supported.". I tried creating a web page in the website and test the MembershipProvider, everything works just fine when woeking from within the website. Any ideas or link for how to use custom (not SqlMembershipProvider) MembershipProvider will be really appreciated! Edit: The method ValidateUser does work. The overriden CreateUser doesn't work I tried Override Sub CreateUser(.......) As MembershipUser Return New User() End Sub But I still get the same excetption as before.

• fb:request-form in iframe redirects away from facebook

  - by IkimashoZ

  I have an <fb:requestform> in an iFrame Facebook app. I have set target="_parent", so that the callback will target the parent iFrame and not itself, which seems to work as expected. But, instead of my desired file loading, I get redirected to my server. Checking the response of the requestform's POST in Firebug revealed this: <script type="text/javascript"> top.location.href = "http://www.facebook.com/login.php?api_key=***&v=1.0&req_perms=&next=http%3A%2F%2F***"; </script> I have already had this same problem when sending jQuery AJAX requests to update various elements in an iFrame. I solved the problem by making sure my headers contain P3P: CP="CAO PSA OUR". That is indeed set for this call as well (can be seen clearly in Firebug), but I still get redirected to facebook.com/login.php.

• How do I change JAVASCRIPT_DEFAULT_SOURCES for my application?

  - by Adam Lassek

  When you call javascript_include_tag :defaults you usually get: prototype.js, effects.js, dragdrop.js, and controls.js. These are stored in a constant in ActionView::Helpers::AssetTagHelper called 'JAVASCRIPT_DEFAULT_SOURCES`. My application uses jQuery, so I want to replace the Prototype references with something more useful. I added an initializer with these lines, based on the source code from jRails: ActionView::Helpers::AssetTagHelper::JAVASCRIPT_DEFAULT_SOURCES = %w{ jquery-1.4.min jquery-ui jquery.cookie } ActionView::Helpers::AssetTagHelper::reset_javascript_include_default But when I do this, I get: warning: already initialized constant JAVASCRIPT_DEFAULT_SOURCES during startup. What's the correct way of changing this value? In the source code it checks for the constant before setting it, but apparently that happens before it runs the initializer scripts. The Rails 3.0 release will provide much greater flexibility with choice of JS libraries, so I guess this is a problem with an expiration date.

• Convert C# event handling to VB.NET

  - by Quandary

  Question: The following C# code: public event RemoteAPI.NotifyCallback Notify { add { s_notify = value; } remove { Console.WriteLine("TODO : Notify remove."); } } How do I convert this to VB.NET ? It implements an interface: Public Interface ICallsToServer ''' <summary> ''' Function to call the server from the client ''' </summary> ''' <param name="n">Some number</param> ''' <returns>Some interesting text</returns> Function SomeSimpleFunction(ByVal n As Integer) As String ''' <summary> ''' Add or remove callback destinations on the client ''' </summary> Event Notify As NotifyCallback End Interface The VB.NET automatically generated code was: Public Event Notify(ByVal s As String) Implements RemoteAPI.ICallsToServer.Notify

• FOX toolkit, file concatentation

  - by Robb

  I'm using the FOX Toolkit and C++ to develop a GUI. I'm Having an issue with the FXFile::concat(...) command. The method looks like: FXFile::concat(const FXString & srcfile1, const FXString & srcfile2, const FXString & dstfile, FXbool overwrite = false And when I call it with the srcfile1 and dstfile being the same thing (because I need to simply add to srcfile1), the method does not work. dstfile is empty. Anyone have experience with FOX and this concatentation problem? I'm open to other suggestions as well, including boost.

• Caching view-port based Geo-queries

  - by friism

  I have a web app with a giant Google Map in it. As users pan and zoom around on the map, points are dynamically loaded through AJAX call which include the viewport bounds (NE and SW corner coordinates) and some other assorted parameters. How do I cache these request for points? The problem is that the parameters are highly variable and (worst) not discrete i.e. floats with a lots of decimal places. I'm using ASP.NET-MVC/C#/LINQ2SQL/SQL-Server but the problem is not tied to that platform. This is the signature of the the relevant method: [AcceptVerbs(HttpVerbs.Post)] public JsonResult Data(string date, string categories, string ne_lat, string ne_lng, string sw_lat, string sw_lng)

• Best placement for javascript in Asp.net MVC app that heavily uses partial views

  - by KallDrexx

  What is the best place for javascript that is specific to a partial view? For example, if I have a partial view (loaded via ajax call) with some divs and I want to turn those divs into an accordian, would it be better put the $("#section").accordion() in script tags inside of the partial view, or in a .js file in the function that retrieves that partial view and inserts it into the DOM? Obviously, common methods I will be keeping in a .js file, however I am more talking about javascript very specific to the partial view itself. Most things I find on the net seem to say to put all javascript into a separate .js but nothing addresses the idea of partial views.

• SQL Select Permissions

  - by Brandi

  I have a database that I need to connect to and select from. I have an SQL Login, let's call it myusername. When I use the following, no SELECT permission shows up: SELECT * FROM fn_my_permissions ('dbo.mytable', 'OBJECT') GO Several times I tried things like: USE mydatabase GO GRANT SELECT TO myusername GO GRANT SELECT ON DATABASE::mydatabase TO myusername GO GRANT SELECT ON mytable TO myusername GO It says the queries execute successfully, but there is never any difference in the first query. What simple thing am I missing to grant database level select permissions. As a note, I made double sure it was the correct user, correct database, and I have already tried granting table level select permissions. So far I keep getting the error: SELECT permission denied on object 'mytable', database 'mydatabase', schema 'dbo'. Any ideas what I'm missing? Thanks in advance.

• TFS Build Configuration Vs Test Manager

  - by Ben

  Hi, I have been tasked with setting up TFS 2010 for my company. After setting up TFS and configuring the basics (New collection, project, adding solution to souce control), i thought i would try out some unit testing with it. I configured the Build Controller and Agent for my solution and added in some basic unit tests. These ran ok and did exactly what i would expect (i broke the build then ran the Build Definition, and it showed me where the errors were). My question is, what advantages (apart from the "Black box call stack logger") does Test Manager have over the TFS builds? Is it worth the extra effort of setting that up and configuring it? Only knowing the basics of what Test Manager is, that may be a very naive question to ask, and i appoligise if it is. Thanks

• Typescript + requirejs: How to handle circular dependencies?

  - by Aymeric Gaurat-Apelli

  I am in the process of porting my JS+requirejs code to typescript+requirejs. One scenario I haven't found how to handle is circular dependencies. Require.js returns undefined on modules that are also dependent on the current and to solve this problem you can do: MyClass.js define(["Modules/dataModel"], function(dataModel){ return function(){ dataModel = require("Modules/dataModel"); ... } }); Now in typescript, I have: MyClass.ts import dataModel = require("Modules/dataModel"); class MyClass { dataModel: any; constructor(){ this.dataModel = require("Modules/dataModel"); // <- this kind of works but I lose typechecking ... } } How to call require a second time and yet keep the type checking benefits of typescript? dataModel is a module { ... }

• CodeIgniter - Post multiple arrays to controller

  - by Bobe

  I have a dynamically generated form that allows users to enter new data and edit existing data. When the form is submitted, it collates the input values and groups them according to whether they are new or not, the former being denoted by class="new-entry". So the function generates two arrays: updateData and insertData. Both arrays are of similar formats: [ 0: { 'id' = 1, 'value' = foo }, 1: { 'id' = 1, 'value' = 'bar' }, etc... ] I am combining them into a new array object to send via ajax to the controller: var postData = { 'update_data': updateData, 'insert_data': insertData }; Then in the ajax call: $.post(url, postData, function() { // some code }); However, in the controller, doing print_r($this->input->post()) or print_r($_POST) as a test only returns Array(). Even $this->input->post('update_data') returns nothing. How can I retrieve these arrays in the controller?

• Strange thing about .NET 4.0 filesystem enumeration functionality

  - by codymanix

  I just read a page of "Whats new .NET Framework 4.0". I have trouble understanding the last paragraph: To remove open handles on enumerated directories or files Create a custom method (or function in Visual Basic) to contain your enumeration code. Apply the MethodImplAttribute attribute with the NoInlining option to the new method. For example: [MethodImplAttribute(MethodImplOptions.NoInlining)] Private void Enumerate() Include the following method calls, to run after your enumeration code: * The GC.Collect() method (no parameters). * The GC.WaitForPendingFinalizers() method. Why the attribute NoInlining? What harm would inlining do here? Why call the garbage collector manually, why not making the enumerator implement IDisposable in the first place? I suspect they use FindFirstFile()/FindNextFile() API calls for the imlementation, so FindClose() has to be called in any case if the enumeration is done.

• Mobile Safari iPhone Development - Multiple buttons in a row

  - by Thomas

  Hello all: I'm an iPhone developer, but new to web development. I've done some basic HTML websites and made one in iWeb as well. I'm trying to branch out to actual mobile development now, so I checked out Dashcode. Anyway, I'm trying to put a Call Button, Mail Button, and Map Button in horizontal alignment. I realize that I can add a Column Layout and have two buttons in a row, but that's the most I've gotten. Any ideas? Thanks! Thomas

• getting window screenshot windows API

  - by Oliver

  Hi, I am trying to make a program to work on top of an existing GUI to annotate it and provide extra calculations and statistical information. I want to do this using image recognition, as I have learned a fair amount about this in University using Matlab and similar things. I can get a handle to the window I want to perform image recognition on, but I don't know how to turn that handle into an image of that window, and all its visible child windows. I suppose I am looking for something like the screenshot function, but restricted to a single window. How would I go about doing this? I suppose I'd need something like a .bmp to mess about with. Also, it would have to be efficient enough that I could call it several times a second without my PC grinding to a halt. Hopefully this isn't an obvious question, I typed some things into google but didn't get anything related.

• How do you implement file drag-and-drop upload in Google Chrome?

  - by Chris R

  I've found several tutorials online about implementing file drag/drop with Firefox 3.6 (they involve using a FileReader object to get the file binary data). However, I cannot create a FileReader object in Chrome on Windows or Mac. Does anyone know what the API is to read and manipulate data from a drag-and-dropped file in Chrome? If I can get the binary data of the file, I already have the rest of the code to perform the upload. Note: I've also tried using the getAsBinary() function call on the file object of the drag event (event.dataTransfer.file) but I believe that is a Mozilla-specific function and not implemented in Chrome. Also, I'm not interested in a solution using google gears or one that requires a user to select files from a dialog. I'm specifically trying to implement a drag-and-drop file upload.

• How do i enable transactions

  - by acidzombie24

  I have a similar question of how to check if you are in a transaction. Instead of checking how do i allow nested transactions? I am using Microsoft SQL File Database with ADO.NET. I seen examples using tsql and examples starting transactions using begin and using transaction names. When calling connection.BeginTransaction i call another function pass in the same connection and it calls BeginTransaction again which gives me the exception SqlConnection does not support parallel transactions. It appears many microsoft variants allow this but i cant figure out how to do it with my .mdf file. How do i allow nested transactions with a Microsoft SQL File Database using C# and ADO.NET?

• Bind a users role to dropdown?

  - by Dynde

  Hi... I'm trying to bind a selected user's role to a dropdown-list. The purpose of this is to be able to change said user's role. I'm attempting this inside a formview hooked up to a linqdatasource which contains a row from the aspnet_User table. The dropdown list is hooked up to a linqdatasource of all the roles in the aspnet_Roles table (with DataValueField="RoleID", DataTextField="RoleName"). I figured it would be possible with something like: SelectedValue='<%# Bind("aspnet_UsersInRole[0].aspnet_Role.RoleID") %>' But this throws a parser exception, about the bind call not being correctly formatted. The roles are there, they show up when I remove the "SelectedValue" Can anyone point me in the right direction?
