  • 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.

  • Rails 2.3.4 Vs Rails 3 + Book - Beginner in RoR

    - by zengr
    Hi, I have started with Ruby and Rails development and I am a Java developer from the last 2 years (student). I am in for two things: Learn Ruby Make my website on ROR I have Agile Web Development with Rails, 2nd Edition. So, here are my questions: How is the Agile Web Development with Rails book to start with, where I don't know anything about Ruby and proficient with Java. What is the difference between 2nd and 3rd edition? People say the changes are irrelevant for a starter, how far is that statement correct? Should I start with Rails 2.3.4 or Rails 3 (around the corner)?

  • Practices for Foreground/Background threads in .NET

    - by Andrei Taptunov
    I work with in-house legacy communication framework which exposes some high level abstractions. These abstractions are wrappers with some logic around .NET threads. When I looked at code I've noticed that some abstractions are wrappers around foreground threads while others are wrappers around background threads. The sad thing is that I don't see any logic why in some cases foreground threads are used and background in other cases. Are there any guidelines or patterns & practices when it's better to choose one over another on server side and client side (I believe there should be some difference)?

  • java.net.SocketException: Software caused connection abort: socket write error

    - by npinti
    Hi guys, I am trying to send an image from a Java desktop application to a J2ME application. The problem is that I am getting this exception: java.net.SocketException: Software caused connection abort: socket write error I have looked around on the net, and although this problem is not that rare, I was unable to find a concrete solution. I am transforming the image into a byte array before transferring it. These are the methods found on the desktop application and on the J2ME respectively public void send(String ID, byte[] serverMessage) throws Exception { //Get the IP and Port of the person to which the message is to be sent. String[] connectionDetails = this.userDetails.get(ID).split(","); Socket sock = new Socket(InetAddress.getByName(connectionDetails[0]), Integer.parseInt(connectionDetails[1])); OutputStream os = sock.getOutputStream(); for (int i = 0; i < serverMessage.length; i++) { os.write((int) serverMessage[i]); } os.flush(); os.close(); sock.close(); } private void read(final StreamConnection slaveSock) { Runnable runnable = new Runnable() { public void run() { try { DataInputStream dataInputStream = slaveSock.openDataInputStream(); int inputChar; StringBuffer results = new StringBuffer(); while ( (inputChar = dataInputStream.read()) != -1) { results.append((char) inputChar); } dataInputStream.close(); slaveSock.close(); parseMessage(results.toString()); results = null; } catch(Exception e) { e.printStackTrace(); Alert alertMsg = new Alert("Error", "An error has occured while reading a message from the server:\n" + e.getMessage(), null, AlertType.ERROR); alertMsg.setTimeout(Alert.FOREVER); myDisplay.setCurrent(alertMsg, resultScreen); } } }; new Thread(runnable).start(); } I am sending the message across a LAN, and I have no problems when I send short text messages instead of images. Also, I used wireshark and it seems that the desktop application is only sending part of the message. Any help would be highly appreciated. Also, everything works on the J2ME simulator. Thanks.

  • Using "Show values as" option in Excel 2007 pivot table when source is SSAS cube?

    - by Brad
    I have an Excel 2007 pivot table showing "Year" across the top and "Month" down the side. What I am trying to do is represent the values as "% Difference" from the same month of the previous year. (Ex. If Jan-07 is $100,000 and Jan-08 is $120,000, I would like Jan-08 to show '20%'). However, every time I try to do this (using the "Show values as" tab of Value Field Settings) all of my numbers go to '#N/A'. Is there a way to do this using an Analysis Services cube as the data source? When I do this exact same thing using data on a different sheet as the data source for the pivot table, it works fine. Thanks in advance for any insight into this.

  • MVVM- How would I go about propagating settings between my main view-model (and other view-models) a

    - by Justin
    I am building a settings dialog for my application and right now all of the settings correspond with settings on the main view-model, but as I add more view's and view-models some may not. I need to know what the best practice is for loading the current settings into the settings dialog and then saving the settings to thier corresponding view-models if the user clicks okay. I will not be using the Properties.Settings.Default system to store settings since I want my application to be as portable as possible and this would store user scoped settings in the directory: C:\Users\ username \Local Settings\Application Data\ ApplicationName Instead of in my application's directory. In case it makes any difference I am using the MVVM Light Toolkit by Laurent Bugnion.

  • jQuery DOM element creation vs innerHTML

    - by Mohammad
    While having one of my questions answered, cletus mentioned that when creating elements in jQuery it's better to use direct DOM element creation, instead of innerHTML. I tried googling it but I wasn't able to find a good article with comparisons. I've provided this code bellow as an example and I was wondering if someone could help me rewrite it in direct DOM element creation form in hope that i would also learn the difference afterwards. var img = $(this); img.append('<p class="cap"><a href="'+img.parent().attr('href')+'">'+ img.attr('title')+'</p></a>'); Thanks so much.

  • Sharing ASP.NET State databases between multiple apps

    - by MikeWyatt
    Is it better for a collection of ASP.NET web apps to share the same session database, or should each one have its own? If there is no significant difference, having a single database would be preferable due to easier maintenance. Background My team has an assortment of ASP.NET web apps, all written in either Monorail 1.1 or ASP.NET MVC 1.0. Each app currently uses a dedicated session state database. I'm working on adding a new site to that list, and am debating whether I should create another new session database, or just share an existing one with another app.

  • Does anyone know of a code change management tool that can highlight code changes in Visual Studio?

    - by Leejo
    Hey all, I am trying to find a tool that can highlight code changes in Visual Studio so they can be easily found and reviewed. Below are some requirements for what we are looking for... Identify and use a difference highlighting tool that meets the following criteria: • can highlight areas that need to be reviewed • there is a place to enter comments • retains line numbering from code • preference for doing within IDE Issue addressed: Hard to see what was changed in code - changes not identified. Coders do not provide administrators diffs. No tool that does a nice job to identify differences. Daunting/time consuming to provide a good diff. When highlighting differences was provided, loss of line numbers was a substantial issue (was worse).

  • Unit testing with django-celery?

    - by Jason Webb
    I am trying to come up with a testing methodology for our django-celery project. I have read the notes in the documentation, but it didn't give me a good idea of what to actually do. I am not worried about testing the tasks in the actual daemons, just the functionality of my code. Mainly I am wondering: How can we bypass task.delay() during the test (I tried setting CELERY_ALWAYS_EAGER = True but it made no difference)? How do we use the test settings that are recommended (if that is the best way) without actually changing our settings.py? Can we still use manage.py test or do we have to use a custom runner? Overall any hints or tips for testing with celery would be very helpful.

  • Impersonation and Delegation

    - by Samuel Kim
    I am using impersonation is used to access file on UNC share as below. var ctx = ((WindowsIdentity)HttpContext.Current.User.Identity).Impersonate(); string level = WindowsIdentity.GetCurrent().ImpersonationLevel); On two Windows 2003 servers using IIS6, I am getting different impersonation levels: Delegation on one server and Impersonation on the other server. This causes issues where I am unable to access the UNC share on the server with 'Impersonation' level. What could be causing this difference? I searched through machine.config and IIS settings for the app pool, site and virtual directories - but aren't able to find the cause of this problem.

  • Design of Business Layer

    - by Adil Mughal
    Hi, We are currently revamping our architecture and design of application. We have just completed design of Data Access Layer which is generic in the sense that it works using XML and reflection to persist data. Any ways now we are in the phase of designing business layer. We have read some books related to Enterprise Architecture and Design so we have found that there are few patterns that can be applied on business layer. Table Pattern and Domain Model are example of such patterns. Also we have found Domain Driven Design as well. Earlier we decided to build Entities against table objects. But we found that there is difference in Entities and Value Objects when it comes to DDD. For those of you who have gone through such design. Please guide me related to pattern, practice and sample. Thank you in advance! Also please feel free to discuss if you didn't get any point of mine.

  • Dynamic adding of usercontrols not showing control on page

    - by Phil
    I am trying to insert a user control dynamically into my default.aspx page via the following method in the page_init: Dim control As UserControl = LoadControl("~\Modules\Content.ascx") Controls.Add(control) When I run the page there is no sign of the usercontrol. Am I using the correct code to insert the usercontrol? Is there an alternative method of insertion available? Does the fact that the usercontrol has a page_load make a difference? Do I need to register the control in my aspx page at design time? Thanks in advance for any assistance you can offer.

  • Getting the starting shortcut in c#

    - by Flores
    Lets say that I have an executable and when it is started I want to know how it's started. I.e. I would like to know if it is started with a shortcut or directly. With this: string test = Environment.GetCommandLineArgs()[0]; I can get the path of the executable, but this is always the same, even if it's started by a shortcut. Lets say my executable is named c:\text.exe and I start it directly, then test = 'c:\test.exe' If I create a shortcut i.e. c:\shortcut.lnk (with target c:\test.exe) I want test to be 'c:\shortcut.exe' but it is 'c:\test.exe' I strongly suspect this to be impossible because the OS handles the shortcut part and the executable never can see the difference, but maybe someone has a creative idea?

  • When to use buildout:eggs and when to install via zc.recipe.egg ?

    - by chiggsy
    There seem to be more than one way to install eggs into a buildout. Way 1: [buildout] ... eggs = eggname othereggname ... Way 2: [buildout] ... parts = eggs [eggs] recipe = zc.recipe.egg eggs = eggname = othereggname Both ways work. ( variation on way 2 would be to install each requirement as a separate part. ) What is the difference between these 2 methods? For my projects, I'm using buildout with djangorecipe and mr.developer.

  • WCF - Network Cost

    - by Mubashar Ahmad
    Dear Devs I have a wcf service deployed on IIS with basicHttpBinding and aspNetCompatibilityEnabled=true I have a test client as well which invokes multiple service functions simultaneously. To check the performance of service call on client and server I calculated the Avg time it takes to complete a service request on client(in proxy code) and on server as well. after a test of 8 hrs (server and client were on the same machine) i came to know that average response time on client is around 34ms where as the Avg execution time on server is around 3ms so the difference is 31ms. I would like to know why every call is taking 31ms is it justified? and how can i reduce this?

  • close fails on database connections (managed connection cleanup fails) in websphere 7 but not in web

    - by mete
    I have a simple method (used in a web application through servlets) that gets a connection from a JNDI name and issues a select statement (get connection, issue select, return result, close the connection etc. in finally). Due to other methods in the application the connection is set as autocommit=false. This method works normally in websphere 6.1 as well as in glassfish and weblogic. However, in websphere 7, it receives cleanup failed error when I close the connection because, it says, the connection is still in a transaction. Because I was not updating anything I did not commit or rollback the connection in this method (which can be wrong). If I add commit before closing the connection, it works. My question is why it works in websphere 6.1 (and other containers) and why not in websphere 7 ? What can be the cause of this difference ?

  • similarity between strings - sql server 2005

    - by csetzkorn
    Hi, I am looking for a simple way (UDF?) to establish the similarity between strings. The SOUNDEX and DIFFERENCE function do not seem to do the job. Similarity should be based on number of characters in common (order matters). For example: Spiruroidea sp. AM-2008 and Spiruroidea gen. sp. AM-2008 should be recognised as similar. Any pointers would be very much appreciated. Thanks. Christian

  • 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.

  • IIS7 + ASP.NET MVC Client Caching Headers Not Working

    - by Tobin Harris
    Hey folks I've deployed an ASP.NET MVC app on IIS7 and Windows Server 2008. I've read posts on here, and around the web, but can't get the darn client-side caching to work. I'm trying to cache everything in the /Content folder. So far I've select that folder in IIS manager, and set the appropriate HTTP Response Headers (under Common Headers). I've also checked the web.config file in the /Content folder and the values there are being set. All resources in /Content come back with this (from FireBug): Cache-Control no-cache, no-store, must-revalidate Pragma no-cache Content-Type image/png Expires -1 Last-Modified Sun, 11 Oct 2009 19:01:40 GMT Accept-Ranges bytes Etag "f318d643a54aca1:0" Server Microsoft-IIS/7.0 X-Powered-By ASP.NET Date Sun, 11 Oct 2009 20:40:01 GMT Content-Length 620 Note the Cache-Control and Expires values for this static image being requested. The site is currently compiled in Debug (this will change), but surely that wouldn't make a difference? Obviously I'm overlooking something, any ideas would be appreciated. Thanks

  • Grouping timestamps by interval between timestamps, then calculating from group MySQL

    - by Emile
    To put this question into context, I'm trying to calculate "time in app" based on an event log. Assume the following table: user_id event_time 2 2012-05-09 07:03:38 3 2012-05-09 07:03:42 4 2012-05-09 07:03:43 2 2012-05-09 07:03:44 2 2012-05-09 07:03:45 4 2012-05-09 07:03:52 2 2012-05-09 07:06:30 I'd like to get the difference between the highest and lowest event_time from a set of timestamps that are within 2 minutes of eachother (and grouped by user). If a timestamp is outside of a 2 minute interval from the set, it should be considered a part of another set. Desired output: user_id seconds_interval 2 7 (because 07:03:45 - 07:03:38 is 7 seconds) 3 0 (because 07:03:42) 4 9 (because 07:03:52 - 2012-05-09 07:03:43) 2 0 (because 07:06:30 is outside 2 min interval of 1st user_id=2 set) This is what I've tried, although I can't group on seconds_interval (even if I could, I'm not sure this is the right direction): SELECT (max(tr.event_time)-min(tr.event_time)) as seconds_interval FROM some_table tr INNER JOIN TrackingRaw tr2 ON (tr.event_time BETWEEN tr2.event_time - INTERVAL 2 MINUTE AND tr2.event_time + INTERVAL 2 MINUTE) GROUP BY seconds_interval

  • Should I typecast in PHP when defining my vars?

    - by Borislav
    I am sorry if this is more of a theory question then a real life problem but it is a real life situation for me. We were commenting on the way PHP works with vars and how memory heavy it is on the server due to its "mixed vars" and something occured to me - why not typecast right from the start? So I guess my quesion is: Whould it make any difference for the server load if all you PHP vars were"pre-casted"? Example: protected $_id; VS protected (int) $_id;

  • How do I create a reusable WF sequential workflow?

    - by djgiard
    I have two customers that have the same workflow (Create file -transport file - wait for response - send response to internal team); however the implementation of each step is different for each customer. For example, one customer requires a flat file to be sent via SFTP, while the other customer requires an XML file to be sent via FTP. I'd like to create a sequential workflow, using Microsoft Workflow Foundation (WF) and reuse this workflow for multiple vendors. Each action's call to an external module can use the same interface, but a different concrete implementation. However, I'm unfamiliar with WF and I'm not sure how to implement this. Can someone point me to the proper way to use this pattern? Will it make a difference whether I choose WF 3.5 or WF 4.0? Thank you.

  • Should I use `!IsGood` or `IsGood == false`?

    - by chills42
    I keep seeing code that does checks like this if (IsGood == false) { DoSomething(); } or this if (IsGood == true) { DoSomething(); } I hate this syntax, and always use the following syntax. if (IsGood) { DoSomething(); } or if (!IsGood) { DoSomething(); } Is there any reason to use '== true' or '== false'? Is it a readability thing? Do people just not understand Boolean variables? Also, is there any performance difference between the two?

  • How can I equalize the heights of text input fields?

    - by David
    What is the best way to equalize the height of my <select..> elements and my <input type="text"..> elements? It's proving difficult because of differences in box-sizing models. Google Chrome's user agent stylesheet has this: select { -webkit-box-sizing: border-box; } ..whereas other text input fields use the content box model. Why the difference? Should I perhaps make all of my text-based input fields use the border-box model? BTW, I'm using standards-compliant mode (by using <!DOCTYPE html>).
