  • Installing Tangible T4 Editor in VS 2010 RC

    - by Stomp
    I installed the (free) Tangible T4 Editor from the VS Gallery, and shut down/restarted VS. I run on XP under an Administrator account. VS Extension Manager indicates that the editor is installed and enabled. Here is my problem: When I do Add New Item (as in the video here), I don't see any of the Tangible templates. What have I missed? (BTW, I looked around some more, found the T4 Toolbox, installed that, and still see no new templates for Tangible or the toolbox). Thanks!

But if I open this page inside VS2008 in browser mode this control starts to do unexpected actions. It's the Telerik RadEditor for Sharepoint v. 5.3.2.0.

  • Teradata equivalent of persisted computed column (in SQL Server)

    - by Cade Roux
    We have a few tables with persisted computed columns in SQL Server. Is there an equivalent of this in Teradata? And, if so, what is the syntax and are there any limitations? The particular computed columns I am looking at conform some account numbers by removing leading zeros - an index is also created on this conformed account number: ACCT_NUM_std AS ISNULL(CONVERT(varchar(39), SUBSTRING(LTRIM(RTRIM([ACCT_NUM])), PATINDEX('%[^0]%', LTRIM(RTRIM([ACCT_NUM])) + '.' ), LEN(LTRIM(RTRIM([ACCT_NUM]))) ) ), '' ) PERSISTED With the Teradata TRIM function, the trimming part would be a little simpler: ACCT_NUM_std AS COALESCE(CAST(TRIM(LEADING '0' FROM TRIM(BOTH FROM ACCT_NUM))) AS varchar(39)), '' ) I guess I could just make this a normal column and put the code to standardize the account numbers in all the processes which insert into the table. We did this to put the standardization code in one place.

  • In .NET, Why Can I Access Private Members of a Class Instance within the Class?

    - by AMissico
    While cleaning some code today written by someone else, I changed the access modifier from Public to Private on a class variable/member/field. I expected a long list of compiler errors that I use to "refactor/rework/review" the code that used this variable. Imagine my surprise when I didn't get any errors. After reviewing, it turns out that another instance of the Class can access the private members of another instance declared within the Class. Totally unexcepted. Is this normal? I been coding in .NET since the beginning and never ran into this issue, nor read about it. I may have stumbled onto it before, but only "vaguely noticed" and move on. Can anyone explain this behavoir to me? I would like to know the "why" I can do this. Please explain, don't just tell me the rule. Am I doing something wrong? I found this behavior in both C# and VB.NET. The code seems to take advantage of the ability to access private variables. Sincerely, Totally Confused Class Jack Private _int As Integer End Class Class Foo Public Property Value() As Integer Get Return _int End Get Set(ByVal value As Integer) _int = value * 2 End Set End Property Private _int As Integer Private _foo As Foo Private _jack As Jack Private _fred As Fred Public Sub SetPrivate() _foo = New Foo _foo.Value = 4 'what you would expect to do because _int is private _foo._int = 3 'TOTALLY UNEXPECTED _jack = New Jack '_jack._int = 3 'expected compile error _fred = New Fred '_fred._int = 3 'expected compile error End Sub Private Class Fred Private _int As Integer End Class End Class

  • In VB.net websites, VS2008 ALWAYS uses space indentation for new files

    - by Jez
    So, I've changed my settings in Tools | Options | Text Editor, for All Languages, Basic, and C#, to having Block indenting, and 'Keep tabs'. I've also tried this with Smart indenting too. Now, although once I start editing a file, its auto indentation is done with tabs, when I create a new web form in my ASP.net website, VS2008 insists on creating the initial code with space indentation. So for example, I'll get an aspx.vb file for my new page like so: Partial Class Admin_Index Inherits System.Web.UI.Page End Class Note that the 'Inherits' line is SPACE-indented, even though I have the text editor settings set to keep tabs. Is there any way I can make the default created files indented with tabs, not spaces? Or is VS just too stubborn? :-) By the way, please don't just respond and say this is petty as I can quickly change that one line of indentation to using a tab. I know this, but I have a software team that find it irritating as we have an SVN hook that prevents checkins if there's any space-indentation. It would be very useful if any newly-created files have tab indentation from the start, rather than us having to change it every time.

  • best practices - multiple functions vs single function with switch case

    - by Amit
    I have a situation where I need to perform several small (but similar) tasks. I can think of two ways to achieve this. First Approach: function doTask1(); function doTask2(); function doTask3(); function doTask4(); Second Approach: // TASK1, TASK2, ... TASK4 are all constants function doTask(TASK) { switch(TASK) { case TASK1: // do task1 break; case TASK2: // do task2 break; case TASK3: // do task3 break; case TASK4: // do task4 break; } } A few more tasks may be added in future (though the chances are rare. but this cannot be ruled out) Please suggest which of the two approaches (or if any other) is a best practice in such a situation.

  • Is it possible to run my Windows Form application in Windows CE platform?

    - by Fakhrul
    I am new in Windows CE development and never done it yet. Need some advise from the expert in here. In our current project, we are developing a client-server application. The client side is using a windows form application that are base on Windows XP OS while the server is a web base application. This question are related to the client application (Windows Form). This application are using Sql Server Express Edition for data storage. The data is stored in XML object format. It also can transfer a data from client to server via web service. It also interact with hardware such as Magnetic Stripe Reader, Contactless Smart Card Reader, and a thermal printer. Most of the communication between hardware device and systems are base on Serial Port. It is use standard app.config for the configuration and is a multi threaded application. There is a new requirement to use a Handheld device which is use a Windows CE platform. This handheld included the required equipment such as Contactless Smart Card Reader, Printer and Magnetic Stripe Reader. Instead of developing a new client application, is it possible to me to convert my current application that are base on Windows XP to Windows CE? If yes, how can I do that? If no, is it any other brilliant suggestion to do this? Thanks in advance. Software Engineer

  • C# / Winforms - Visually remove button click event

    - by Wayne Koorts
    .NET newbie alert Using Visual C# 2008 Express Edition I have accidentally created a click event for a button. I then deleted the automatically-created method code, which resulted in an error saying that the function, which had now been referenced in the form loading code, could no longer be found. Deleting the following line from the Form1.Designer.cs file's InitializeComponent() function... this.btnCopy.Click += new System.EventHandler(this.btnCopy_Click); ... seems to do the trick, however, it makes me feel very dirty because of the following warning at the beginning of the #region: /// Required method for Designer support - do not modify /// the contents of this method with the code editor. I haven't been able to find a way to do this using the form designer, which I assume is the means implied by this warning. What is the correct way to do this?

  • Switch from Microsofts STL to STLport

    - by Laserallan
    Hi! I'm using quite much STL in performance critical C++ code under windows. One possible "cheap" way to get some extra performance would be to change to a faster STL library. According to this post STLport is faster and uses less memory, however it's a few years old. Has anyone made this change recently and what were your results?

  • How to restrict access to a class's data based on state?

    - by Marcus Swope
    In an ETL application I am working on, we have three basic processes: Validate and parse an XML file of customer information from a third party Match values received in the file to values in our system Load customer data in our system The issue here is that we may need to display the customer information from any or all of the above states to an internal user and there is data in our customer class that will never be populated before the values have been matched in our system (step 2). For this reason, I would like to have the values not even be available to be accessed when the customer is in this state, and I would like to have to avoid some repeated logic everywhere like: if (customer.IsMatched) DisplayTextOnWeb(customer.SomeMatchedValue); My first thought for this was to add a couple interfaces on top of Customer that would only expose the properties and behaviors of the current state, and then only deal with those interfaces. The problem with this approach is that there seems to be no good way to move from an ICustomerWithNoMatchedValues to an ICustomerWithMatchedValues without doing direct casts, etc... (or at least I can't find one). I can't be the first to have come across this, how do you normally approach this? As a last caveat, I would like for this solution to play nice with FluentNHibernate :) Thanks in advance...

  • Schemas and tables versus user-ids in a single table using PostgreSQL

    - by gvkv
    I'm developing a web app and I've come to a fork in the road with respect to database structure and I don't know which direction to take. I have a database with user information that I can structure one of two ways. The first is to create a schema and a set of tables for each user (duplicating the structure for each user) and the second is to create a single set of tables and query information based on user-id. Suppose 100000 users. Here are my questions: Considering security, performance, scalability and administration where does each choice lie? Would the answers change for 1000000 or 10000? Is there a set of best practices that lead to one choice or the other? It seems to me that multiple schemas are more secure since it's trivial to restrict user privileges but what about performance and scalability? Administration seems like a wash since dumping (and restoring) lots of schemas isn't any more difficult than dumping a few.

  • Providing multi-version databases for backward compatibility for production applications/databases.

    - by JavaRocky
    How can I manage multiple versions of a database easily? I have some data (as views as selects for data originating in tables from other schemas), which other database may reference using various means including database synonyms & links. I wish to provide a sort of interface/guarantee in-case future for applications/databases which use this data. All of this is for in the event i need to update the views for correctness or applicability inside my database. How can i achieve this in a maintained, controlled and easy way? I am using Oracle 10g if that matters.

  • How do I get ELMAH to work with SQL Server (permission problems)

    - by Gary McGill
    I've got ELMAH working on my (Cassini) development server, and was quite happy with it, but now that I'm trying to move everything to my production server (IIS7), the honeymoon looks like being over. I've got past the "gotcha" with IIS7, which frankly could have been better highlighted in the documentation, and if I just use the in-memory log then it works. However, I'm trying to get it to use the SQL Server log (as I do on my development system), and I'm getting an error along the lines of: The EXECUTE permission was denied on the object ELMAH_GetErrorsXml Well, fine. I know how to grant database permissions, but I'm really struggling to understand which user and which stored procs/tables I need to grant access to. The thing that's really confusing me is that I didn't have to do anything like this to get it to work on my development server. The only difference I can see is that on my development server it seems to connect as NT AUTHORITY\IUSR, whereas on my production server it seems to connect as NT AUTHORITY\NETWORK SERVICE. (It's just using a trusted connection so I've not explicitly configured it to do that - I presume it's to do with the web server). UPDATE: I've since established that because I'm using Cassini, it was actually logging in as me (an admin) and not IUSR, which explains why I didn't get any permission problems. On my development server, the IUSR account is a member of the public database role, and has access to the required database (again as "public"). There's no explicit granting of object-level permissions. [See update above - this is irrelevant]. On my production server, I've added NETWORK SERVICE in exactly the same way (public database role, explicit access to the database as "public"). Yet, I get this permission error. Why?!! [See update above - the only reason I don't get a permission error is because I'm running as an admin]. And, of course, if the fact that it works locally is just "luck", I will need to know which SPs/tables to grant access to. My guess would be all 3 SPs and not the table, but it would be good (again) to see some documentation that makes this explicit.

  • ASP.Net Custom Field From Query In DataSet

    - by boruchsiper
    I added a new query to a table adapter in a DataSet. This query adds another field to the query whcih is a sum from another table. Here is the full query: SELECT (SELECT COUNT(donationID) AS Expr1 FROM Donations AS da WHERE (dn.donorID = donorID)) AS Count, Solicitor, address1, address2, city, companyName, country, donorID, email, first, last, phoneHome, phoneMobile, phoneWork, state, webURL, zip, (select sum(amount) from Donations as dna where dna.donorID = dn.donorID) as SumDonations FROM Donors AS dn order by last The new field is represented in the last part of the query: (select sum(amount) from Donations as dna where dna.donorID = dn.donorID) as SumDonations I can preview the data in the xsd but the last field "SumDonations" is not showing up as a field I can add to my gridview. I rebuilt the website but no luck. What am I missing?

  • VS2010 method comment block pretty format.

    - by camelCase
    I have just installed the lastest RC of VS2010, which for me represents a shift from VS2008. A new comment formatting feature that I was looking forward to appears to be missing. About 6 months ago I read a Scott Gu blog post that mentioned a new VS2010 feature that would format /// style method comment blocks into more readable formatted regions inline with other code. The Scott Gu blog did not provide a screen shot but I was expecting the VS2010 editor to remove the XML tags from the /// method comment block and render just the essential text comment. Was this feature pulled during the Beta, or is there an option switch urking somewhere?

  • ObjectContext ConnectionString Sqlite

    - by codegarten
    I need to connect to a database in Sqlite so i downloaded and installed System.Data.SQLite and with the designer dragged all my tables. The designer created a .cs file with public class Entities : ObjectContext and 3 constructors: 1st public Entities() : base("name=Entities", "Entities") this one load the connection string from App.config and works fine. App.config <connectionStrings> <add name="Entities" connectionString="metadata=res://*/Db.TracModel.csdl|res://*/Db.TracModel.ssdl|res://*/Db.TracModel.msl;provider=System.Data.SQLite;provider connection string=&quot;data source=C:\Users\Filipe\Desktop\trac.db&quot;" providerName="System.Data.EntityClient" /> </connectionStrings> 2nd public Entities(string connectionString) : base(connectionString, "Entities") 3rd public Entities(EntityConnection connection) : base(connection, "Entities") Here is the problem, i already tried n configuration, already used EntityConnectionStringBuilder to make the connection string with no luck. Can you please point me in the right direction!? EDIT(1) How can i construct a valid connection string?!

  • Why is it bad to use boolean flags in databases? And what should be used instead?

    - by David Chanin
    I've been reading through some of guides on database optimization and best practices and a lot of them suggest not using boolean flags at all in the DB schema (ex http://forge.mysql.com/wiki/Top10SQLPerformanceTips). However, they never provide any reason as to why this is bad. Is it a peformance issue? is it hard to index or query properly? Furthermore, if boolean flags are bad, what should you use to store boolean values in a database? Is it better to store boolean flags as an integer and use a bitmask? This seems like it would be less readable.

  • VS2008 on Win7 64-Bit: Debugging a Windows Service

    - by Richard
    Hi all, I'm trying to debug a Windows Service using VS2008 on Win7 64-Bit. The problem I'm having is that none of my breakpoints are being hit, regardless of which build configuration I choose: x86, x64 or AnyCPU. Using "Attach to Process" after the service has started, none of the breakpoints are hit - yet the IDE doesn't inform me that they won't be hit (by making the solid red circle and outline, for instance) - it simply seems to act as if the breakpoints weren't even there. Can anyone point me in the right direction here? Thanks /Richard.

  • not sure if this is my mistake ~~ vs2010 Add Service Reference fails

    - by gerryLowry
    https://tbe.taleo.net/MANAGER/dispatcher/servlet/rpcrouter the above is from Taleo's API guide. I'm trying to create a WCF Client (e.g.: " Creating Your First WCF Client" http://channel9.msdn.com/shows/Endpoint/Endpoint-Screencasts-Creating-Your-First-WCF-Client/ ) The tbe.taleo... link is from Taleo's API documentation. Likely my understanding is flawed. My assumption is that when the link from Taleo is entered into the vs2010 "Add Service Reference" dialog and GO is clicked, then vs2010 should retrieve a proper WSDL/SOAP envelope back from the Taleo link. That does not happen; instead an error occurs. Fiddler2 (http://fiddler2.com) displays the status code 500 "HTTP/1.1 500 Internal Server Error". [FULL DETAILS BELOW] "WcfTestClient.exe" gives a similar error: [WcfTestClient DETAILS BELOW] QUESTION: is it me, or is the Taleo link flawed?
