  • Choosing between ExtJS and YUI based on application parameters.

    - by Kabeer
    Hello. I need help in taking call to choose between Ext JS and YUI libraries. Here are the key factors I have derived from my application requirements & development process: Complex, windows forms like controls Widgets, Layouts, Utilities Inter widget communication Easy to extend Easy to learn Intuitive & concise coding Strong exception handling Active support / community To update with upcoming technologies (HTML5, etc.) Skins & Themes to be easy to change Skins & Themes to support variety (a text box for different context to appear differently) Support & Utilities for standard protocols (XmlHttp, JSON) Good performance (responsive) Cost is not crucial, but I don't mind saving :)

  • How do you localize/internationalize an MVC Controller when using a SQL based localization provider?

    - by EBarr
    Hopefully this isn't too silly of a question. In MVC there appears to be plenty of localization support in the views. Once I get to the controller, however, it becomes murky. Using meta:resourcekey="blah" is out, same with <%$ Resources:PageTitle.Text%. ASP.NET MVC - Localization Helpers -- suggested extensions for the Html helper classes like Resource(this Controller controller, string expression, params object[] args). Similarly, Localize your MVC with ease suggested a slightly different extension like Localize(this System.Web.UI.UserControl control, string resourceKey, params object[] args) None of these approaches works while in a controller. I put together the below function and I'm using the controllers full class name as my VirtualPath. But I'm new to MVC and assume there's a better way. public static string Localize (System.Type theType, string resourceKey, params object[] args) { string resource = (HttpContext.GetLocalResourceObject(theType.FullName, resourceKey) ?? string.Empty).ToString(); return mergeTokens(resource, args); } Thoughts? Comments?

  • How to generate a compiler error based on an attribute being missing in C#?

    - by RodH257
    I create a number of add-ins for the Revit Structure API. Each tool has to habe a class which implements the interface IExternalCommand. In the latest version of Revit, for your tool to work you need to have two attributes on the class that implements that interface: [Regeneration(RegenerationOption.Manual)] [Transaction(TransactionMode.Automatic)] The values in brackets can change, but there must be something there. Often I am finding myself forgetting to put the attributes on, then when it comes to runtime it crashes. Is there any way in Visual Studio 2010 to add a compiler warning or error saying that if your class implements that interface it must have those 2 attributes? I have resharper if that helps. Can anyone point me into the right direction?

  • How do I solve an unresolved external when using C++ Builder packages (with TForm based classes)?

    - by José Renato
    Hi, i'm working with Bulder C++ 6 and 2010, and i'm having this problem: http://stackoverflow.com/questions/2727001/how-do-i-solve-an-unresolved-external-when-using-c-builder-packages But, the difference here is that i'm using a FORM compiled inside the package, so, take the example above, but in addition i'm including a form classe, like TForm2: class TForm2 : public TForm { __published: // IDE-managed Components TButton *Button1; void __fastcall Button1Click(TObject *Sender); private: // User declarations public: // User declarations __fastcall TForm2(TComponent* Owner); }; //--------------------------------------------------------------------------- extern PACKAGE TForm2 *Form2; //--------------------------------------------------------------------------- So, when i'm trying to use this class in any project the linker stops and give me the unresolved external error. When i got that error i tried to include the word PACKAGE, like this: class PACKAGE TForm2 But, when i tried to compile the PACKAGE, the compiler stops with the unresolved external error: [ILINK32 Error] Error: Unresolved external '__fastcall Forms::TCustomForm::~TCustomForm()' referenced from c:\projects\UNIT2.OBJ How can i solve this problem? PS.: Sorry about the bad English.

  • Use PHP to create a DOC file on a Unix Box based on an HTML webform selection

    - by Gerald Oakham
    Hello, I have an HTML file which contains a webform with multiple questions which have a YES / NO responses. If the question has a YES answer, I would like a predefined ( per question ) section of text to be written to a DOC file on the server, but only AFTER the submit button has been pressed ( this way, if the user changes their mind and changes an answer form YES to NO, I won't have to re-write the doc ). When the user has clicked Submit, The file should be presented as a download. Any Ideas

  • Alter Table Filestream runs even if IF statement is false

    - by Allison
    I am writing a script to update a database to add Filestream capability. The script needs to be able to be run multiple times without erroring. This is what I currently have IF ((select count(*) from sys.columns a inner join sys.objects b on a.object_id = b.object_id inner join sys.default_constraints c on c.parent_object_id = a.object_id where a.name = 'evidence_data' and b.name='evidence' and c.name='DF__evidence_evidence_data') = 0) begin ALTER TABLE evidence SET ( FILESTREAM_ON = AnalysisFSGroup ) ALTER TABLE evidence ALTER COLUMN id ADD ROWGUIDCOL; end GO The first time I run this against the database it works fine. The second time when the if statement should be false it throws an error saying "Cannot add FILESTREAM filegroup or partition scheme since table 'evidence' has a FILESTREAM filegroup or partition scheme already." If I put a simple select into the if statement and take out the alter table filestream on line it functions correctly and does not perform the if statement. So esentially it is always running the alter table filestream on statement even if the if statement is false. Any thoughts or suggestions would be great. Thanks.

  • Are there commercially deployed and used .NET CAS (Code Access Security) based applications?

    - by Dinis Cruz
    I've seen a couple threads here on SO that ask about what CAS is and how to use it.My specific is specifically focused on real-world usages of CAS. For example: DotNetNuke did some efforts in the past to be able to run under Medium Trust: is that still true? what is the % of DNN that run in partial trust (i.e. not full trust)? what & of DNN modules run in partial trust?) Sharepoint defaults to a Partially-Trusted environment on dlls executed from the bin folder: How many 'commercially' available WebParts can run in this bin folder (without changing the policy)? The key here is to be able to point to CAS success stories, so that other companies feel that they should also invest in writing CAS-enabled apps

  • Possible to view T-SQL syntax of a stored proc-based SqlCommand?

    - by mconnley
    Hello! I was wondering if anybody knows of a way to retrieve the actual T-SQL that is to be executed by a SqlCommand object (with a CommandType of StoredProcedure) before it executes... My scenario involves optionally saving DB operations to a file or MSMQ before the command is actually executed. My assumption is that if you create a SqlCommand like the following: Using oCommand As New SqlCommand("sp_Foo") oCommand.CommandType = CommandType.StoredProcedure oCommand.Parameters.Add(New SqlParameter("@Param1", "value1")) oCommand.ExecuteNonQuery() End Using It winds up executing some T-SQL like: EXEC sp_Foo @Param1 = 'value1' Is that assumption correct? If so, is it possible to retrieve that actual T-SQL somehow? My goal here is to get the parsing, etc. benefits of using the SqlCommand class since I'm going to be using it anyway. Is this possible? Am I going about this the wrong way? Thanks in advance for any input!

  • Should I distinguish OpenIDs based on protocol prefix or not? http vs https

    - by Joannes Vermorel
    I have implemented a straightforward OpenID support for my ASP.NET app with DotNetOpenAuth. Yet I recently realized that the implementation was treating http://johndoe.example.com/ as a distinct user compared to https://johndoe.example.com. This lead to quite a few confused users. I am unsure what to do at this point. Is this a bug or a feature? Indeed, I can consider this behavior as a feature: if the user specifies the HTTPS, the user might not want the system to accept HTTP auth in the first place. On the other hand: if the user specifies HTTPS out of sheer cluelessness (the casual web visitor is clueless concerning the purpose of the "S" part), then rejecting it's authentication attempt is confusing. What is considered as the best practice?

  • Possible to load an Enum based on a string name?

    - by Cooter
    OK, I don't think the title says it right... but here goes: I have a class with about 40 Enums in it. i.e: Class Hoohoo { public enum aaa : short { a = 0, b = 3 } public enum bbb : short { a = 0, b = 3 } public enum ccc : short { a = 0, b = 3 } } Now say I have a Dictionary of strings and values, and each string is the name of above mentioned enums: Dictionary<string,short>{"aaa":0,"bbb":3,"ccc":0} I need to change "aaa" into HooBoo.aaa to look up 0. Can't seem to find a way to do this since the enum is static. Otherwise I'll have to write a method for each enum to tie the string to it. I can do that but thats mucho code to write. Thanks, Cooter

  • How to convert none-Latin-based encoded text into UTF-8, or make them coexist on same page?

    - by Yallaa
    Good day, I have a script that scrapes the title/description of remote pages and prints those values into a corresponding charset=UTF-8 encoded page. Here is the problem, whenever a remote page is encoded with non-Latin characters encoding like (Arabic, Russian, Chinese, Japanese etc.) the imported values print as garbled text. I've tried passing those values through either iconv or mb_convert_encoding converters but without much success. Then, I tried detecting the remote encoding first, then change my presentation page's encoding into the remote one instead of the current utf-8, which works okay with the imported values, but the other existing utf-8 content of that language on the page gets garbled instead. Example: If I try to import those values from a Russian windows-1251 into my UTF-8 encoded page which has a mix English/Russian content. I change the imported non-utf-8 string into a utf-8 using either iconv or mb_convert_encoding. I tried: $RemoteValue = iconv($RemoteEncoding, 'UTF-8', $RemoteValue); or $RemoteValue mb_convert_encoding($RemoteValue, "UTF-8", $RemoteEncoding); or $RemoteValue mb_convert_encoding($RemoteValue, "UTF-8", "auto"); without success. If I detect that the remote page is windows-1251 encoded and I change my presentation page (which already has UTF-8 encoded mixed language content) to be similar to the remote page, then the japanese utf-8 content on the existing page gets garbled... Can 2 differently encoded strings coexist on the same page (ex. utf-8 & windows-1251)? Am I using the converters correctly? any hints as to why they don't work? Is there any better way to do this? Thank you for your help

  • Why should the "prime-based" hashcode implmentation be used instead of the "naive" one?

    - by Wilhelm
    I have seen that a prime number implmentation of the GetHashCode function is being recommend, for example here. However using the following code (in VB, sorry), it seems as if that implementation gives the same hash density as a "naive" xor implementation. If the density is the same, I would suppose there is the same probability of cllision in both implementations. Am I missing anything on why is the prime approach preferred? I am supossing that if the hash code is a byte I do not lose generality for the integer case. Sub Main() Dim XorHashes(255) As Integer Dim PrimeHashes(255) As Integer For i = 0 To 255 For j = 0 To 255 For k = 0 To 255 XorHashes(GetXorHash(i, j, k)) += 1 PrimeHashes(GetPrimeHash(i, j, k)) += 1 Next Next Next For i = 0 To 255 Console.WriteLine("{0}: {1}, {2}", i, XorHashes(i), PrimeHashes(i)) Next Console.ReadKey() End Sub Public Function GetXorHash(ByVal valueOne As Integer, ByVal valueTwo As Integer, ByVal valueThree As Integer) As Byte Return CByte((valueOne Xor valueTwo Xor valueThree) Mod 256) End Function Public Function GetPrimeHash(ByVal valueOne As Integer, ByVal valueTwo As Integer, ByVal valueThree As Integer) As Byte Dim TempHash = 17 TempHash = 31 * TempHash + valueOne TempHash = 31 * TempHash + valueTwo TempHash = 31 * TempHash + valueThree Return CByte(TempHash Mod 256) End Function

  • How can I work around SQL Server - Inline Table Value Function execution plan variation based on par

    - by Ovidiu Pacurar
    Here is the situation: I have a table value function with a datetime parameter ,lest's say tdf(p_date) , that filters about two million rows selecting those with column date smaller than p_date and computes some aggregate values on other columns. It works great but if p_date is a custom scalar value function (returning the end of day in my case) the execution plan is altered an the query goes from 1 sec to 1 minute execution time. A proof of concept table - 1K products, 2M rows: CREATE TABLE [dbo].[POC]( [Date] [datetime] NOT NULL, [idProduct] [int] NOT NULL, [Quantity] [int] NOT NULL ) ON [PRIMARY] The inline table value function: CREATE FUNCTION tdf (@p_date datetime) RETURNS TABLE AS RETURN ( SELECT idProduct, SUM(Quantity) AS TotalQuantity, max(Date) as LastDate FROM POC WHERE (Date < @p_date) GROUP BY idProduct ) The scalar value function: CREATE FUNCTION [dbo].[EndOfDay] (@date datetime) RETURNS datetime AS BEGIN DECLARE @res datetime SET @res=dateadd(second, -1, dateadd(day, 1, dateadd(ms, -datepart(ms, @date), dateadd(ss, -datepart(ss, @date), dateadd(mi,- datepart(mi,@date), dateadd(hh, -datepart(hh, @date), @date)))))) RETURN @res END Query 1 - Working great SELECT * FROM [dbo].[tdf] (getdate()) The end of execution plan: Stream Aggregate Cost 13% <--- Clustered Index Scan Cost 86% Query 2 - Not so great SELECT * FROM [dbo].[tdf] (dbo.EndOfDay(getdate())) The end of execution plan: Stream Aggregate Cost 4% <--- Filter Cost 12% <--- Clustered Index Scan Cost 86%

  • How do I select elements based on all their content in jQuery?

    I have a series of <div/>'s as follows: <div>.co.uk</div> <div>.com</div> <div>.gb.com</div> <div>.uk.com</div> <div>.net</div> How do I select just the divs containing .co.uk, .com, .net. If I use: $('div:contains(".co.uk"), div:contains(".com"), div:contains(".net")`) This causes the .gb.com and .uk.com divs to be selected as well.

  • What's a good pure-python, document-based and flat-file database engine?

    - by joe Simpson
    Hi, for development i'd love to have a flat file database with the requirements up in the title, but I don't seem to be able to find a database with these requirements. I can't seem to get MetaKit to work. I only need it to work on the development machine, but in the real world my product will have more data and needs more room and will need something better. Does anyone know of a database engine capable of this or do I need to just use python's pickle and load and save a file? Joe

  • How to calculate unbound column value based on value of bound colum in DatagGridView?

    - by Wodzu
    Hi. I have few columns in my DataGridView, one of them is an unbound column and the DataGridVIew is in VirtualMode. When CellValueNeeded event is called, I want to calculate value of Cells[0] basing on the value of Cells[2] which is in bounded column to the underlaying DataSource. This is how I try to do this: private void dgvItems_CellValueNeeded(object sender, DataGridViewCellValueEventArgs e) { e.Value = dgvItems.CurrentRow.Cells[2].Value * 5; //simplified example } However, I am getting System.StackOverflowException because it seams that call to dgvItems.CurrentRow.Cells[2].Value results in call to another CellValueNeeded event. And so on and so on... However Cells[2] is not an unbound column, so on common sense it should not result in recursive call unless getting value of any column(bound or unbound) firest that event... I can not use here SQL Expression and I can not precalculate e.Value in any SQL call. In real example Cells[2].Value is a key used in HashTable which will return a correct value for the Cells[0] (e.Value). What can I do?

  • Criteria API - How to get records based on collection count?

    - by Cosmo
    Hello Guys! I have a Question class in ActiveRecord with following fields: [ActiveRecord("`Question`")] public class Question : ObcykaniDb<Question> { private long id; private IList<Question> relatedQuestions; [PrimaryKey("`Id`")] private long Id { get { return this.id; } set { this.id = value; } } [HasAndBelongsToMany(typeof(Question), ColumnRef = "ChildId", ColumnKey = "ParentId", Table = "RelatedQuestion")] private IList<Question> RelatedQuestions { get { return this.relatedQuestions; } set { this.relatedQuestions = value; } } } How do I write a DetachedCriteria query to get all Questions that have at least 5 related questions (count) in the RelatedQuestions collection? For now this gives me strange results: DetachedCriteria dCriteria = DetachedCriteria.For<Question>() .CreateCriteria("RelatedQuestions") .SetProjection(Projections.Count("Id")) .Add(Restrictions.EqProperty(Projections.Id(), "alias.Id")); DetachedCriteria dc = DetachedCriteria.For<Question>("alias").Add(Subqueries.Le(5, dCriteria)); IList<Question> results = Question.FindAll(dc); Any ideas what I'm doing wrong?

  • How to port an Ajax CMS based on metadata in Asp.Net MVC?

    - by Maushu
    I'm maintaining a CMS where I have this feeling it was made in the age of dinosaurs (Asp.net 1.0?) and decided to upgrade it with Asp.Net MVC and jQuery. But I have some problems regarding the design/specifications of the CMS which I cannot change. The CMS The CMS uses JavaScript. Alot. As in "I don't load pages, I request new pages using Ajax and render the information using javascript" alot. Not to mention the animations, the weird horizontal apresentation of structures... anyways, besides the first page (that is the login page) every other "page" is just data requested from a WebService that comes with the website. Would MVC have any problems with this design? The Database The database is in a SQL Server 2k8 and, like the CMS, this part is also... interesting. Basically, the user can create data structures using metadata (and saved on the Structure table). These structures are saved on tables that are created (and regenerated when changed) at runtime using said metadata. I don't know how I would implement this part in MVC. The question is, can and should I convert this project to MVC? Any tips regarding the metadata and overuse of ajax?
