  • SQL Server 2005 Error "The user does not have permission to perform this action" - clears up after r

    - by Sylvia
    We're getting the error "The user does not have permission to perform this action" during times of heavy load (regularly, when a trim job occurs). The error clears up when the service accessing sql server is restarted, so it's obviously not a real permissions problems. There's a possibility that the problem is occurring when we're trying to query dm_tran_active_transactions and sys.dm_tran_session_transactions. Any ideas of good places to start looking? thanks for any insights...

  • jqgrid and django models

    - by Andrew Gee
    Hi, I have the following models class Employee(Person): job = model.Charfield(max_length=200) class Address(models.Model): street = models.CharField(max_length=200) city = models.CharField(max_length=200) class EmpAddress(Address): date_occupied = models.DateField() date_vacated = models.DateField() employee = models.ForeignKey() When I build a json data structure for an EmpAddress object using the django serialzer it does not include the inherited fields only the EmpAddress fields. I know the fields are available in the object in my view as I can print them but they are not built into the json structure. Does anyone know how to overcome this? Thanks Andrew

  • Java unchecked method invocation

    - by Sam
    I'm trying to setup a multithreaded application using SQLite4java, and everything is working fine. However, according to the getting started tutorial I am meant to create an object of type "object" and in order to return a value of null (due to use of generic types). Here is the suggested code: queue.execute(new SQLiteJob<Object>() { protected Object job(SQLiteConnection connection) throws SQLiteException { // this method is called from database thread and passed the connection connection.exec(...); return null; } }); Source The following example code I created produces the same error: error: test.java:9: warning: [unchecked] unchecked method invocation: <T,J>execute(J) in com.almworks.sqlite4java.SQLiteQueue is applied to (query<java.lang.Integer>) queue.execute(new query<Integer>()); test.java: import com.almworks.sqlite4java.*; import java.util.ArrayList; import java.io.File; class test{ public static void main(String[] args){ File f = new File("file.db"); SQLiteQueue queue = new SQLiteQueue(f); queue.execute(new query<Integer>()); } } query.java: import com.almworks.sqlite4java.SQLiteException; import com.almworks.sqlite4java.SQLiteJob; import com.almworks.sqlite4java.SQLiteConnection; import com.almworks.sqlite4java.SQLiteStatement; import java.util.ArrayList; class query<T> extends SQLiteJob{ protected ArrayList<Integer> job(SQLiteConnection connection) throws SQLiteException{ ArrayList<Integer> ints = new ArrayList<Integer>(); //DB Stuff return ints; } } I have read a lot about how this particular message appears when people fail to specify a type for an ArrayList. However, I am not attempting to cast the object or do anything with it. It is merely a mechanism implemented by the library developers in order to return a null. I do not believe this to be an issue relating directly to the library, which is why I'm asking this on StackOverflow. I believe it all comes down to my lack of experience with generic types. I've already spent a few hours on this and don't feel like I am getting anywhere. How do I stop the warning?

  • Parameters and Ranges of Values

    - by Randy Minder
    I need to create a report in Crystal 2008 and I've haven't developed a report using Crystal in many years. When the user runs the report, I want them to be able to enter a start date and end date. I assume I can do this by using parameters. My question is this. Can I do this with a single parameter value or will it require two parameter values? Ideally what I would like to do is to allow the user to enter a start and end date in one parameter/prompt combination. Is this possible? Thanks - Randy

  • Cancel outlook meeting requests via MailMessage in C#

    - by BTmuney
    I'm creating an application using the ASP.NET MVC 1 framework in C#, where I have users that register for events. Upon registering, I create an outlook meeting request public string BuildMeetingRequest(DateTime start, DateTime end, string attendees, string organizer, string subject, string description, string UID, string location) { System.Text.StringBuilder sw = new System.Text.StringBuilder(); sw.AppendLine("BEGIN:VCALENDAR"); sw.AppendLine("VERSION:2.0"); sw.AppendLine("METHOD:REQUEST"); sw.AppendLine("BEGIN:VEVENT"); sw.AppendLine(attendees); sw.AppendLine("CLASS:PUBLIC"); sw.AppendLine(string.Format("CREATED:{0:yyyyMMddTHHmmssZ}", DateTime.UtcNow)); sw.AppendLine("DESCRIPTION:" + description); sw.AppendLine(string.Format("DTEND:{0:yyyyMMddTHHmmssZ}", end)); sw.AppendLine(string.Format("DTSTAMP:{0:yyyyMMddTHHmmssZ}", DateTime.UtcNow)); sw.AppendLine(string.Format("DTSTART:{0:yyyyMMddTHHmmssZ}", start)); sw.AppendLine("ORGANIZER;CN=\"NAME\":mailto:" + organizer); sw.AppendLine("SEQUENCE:0"); sw.AppendLine("UID:" + UID); sw.AppendLine("LOCATION:" + location); sw.AppendLine("SUMMARY;LANGUAGE=en-us:" + subject); sw.AppendLine("BEGIN:VALARM"); sw.AppendLine("TRIGGER:-PT720M"); sw.AppendLine("ACTION:DISPLAY"); sw.AppendLine("DESCRIPTION:Reminder"); sw.AppendLine("END:VALARM"); sw.AppendLine("END:VEVENT"); sw.AppendLine("END:VCALENDAR"); return sw.ToString(); } And once built, I use MailMessage, with an alternate view to send out the meeting request: meetingInfo = BuildMeetingRequest(start, end, attendees, organizer, subject, description, UID, location); System.Net.Mime.ContentType mimeType = new System.Net.Mime.ContentType("text/calendar; method=REQUEST"); AlternateView ICSview = AlternateView.CreateAlternateViewFromString(meetingInfo,mimeType); MailMessage message = new MailMessage(); message.To.Add(to); message.From = new MailAddress(from); message.AlternateViews.Add(ICSview); SmtpClient client = new SmtpClient(); client.Send(message); When users get the email in outlook, it shows up as a meeting request, as opposed to a normal email. This works well for sending out updates to the meeting request as well. The only problem that I am having is that I do not know the proper format for sending out a cancellation. I've attempted to examine some meeting request cancellations in text editors and can't seem to pinpoint the difference in the format between cancelling/creating. Any help on this is greatly appreciated.

  • Scala actors: receive vs react

    - by jqno
    Let me first say that I have quite a lot of Java experience, but have only recently become interested in functional languages. Recently I've started looking at Scala, which seems like a very nice language. However, I've been reading about Scala's Actor framework in Programming in Scala, and there's one thing I don't understand. In chapter 30.4 it says that using react instead of receive makes it possible to re-use threads, which is good for performance, since threads are expensive in the JVM. Does this mean that, as long as I remember to call react instead of receive, I can start as many Actors as I like? Before discovering Scala, I've been playing with Erlang, and the author of Programming Erlang boasts about spawning over 200,000 processes without breaking a sweat. I'd hate to do that with Java threads. What kind of limits am I looking at in Scala as compared to Erlang (and Java)? Also, how does this thread re-use work in Scala? Let's assume, for simplicity, that I have only one thread. Will all the actors that I start run sequentially in this thread, or will some sort of task-switching take place? For example, if I start two actors that ping-pong messages to each other, will I risk deadlock if they're started in the same thread? According to Programming in Scala, writing actors to use react is more difficult than with receive. This sounds plausible, since react doesn't return. However, the book goes on to show how you can put a react inside a loop using Actor.loop. As a result, you get loop { react { ... } } which, to me, seems pretty similar to while (true) { receive { ... } } which is used earlier in the book. Still, the book says that "in practice, programs will need at least a few receive's". So what am I missing here? What can receive do that react cannot, besides return? And why do I care? Finally, coming to the core of what I don't understand: the book keeps mentioning how using react makes it possible to discard the call stack to re-use the thread. How does that work? Why is it necessary to discard the call stack? And why can the call stack be discarded when a function terminates by throwing an exception (react), but not when it terminates by returning (receive)? I have the impression that Programming in Scala has been glossing over some of the key issues here, which is a shame, because otherwise it's a truly excellent book.

  • SDK for writing DVD's

    - by Matt Warren
    I need to add DVD writing functionality to an application I'm working on. However it needs to be able to write out files that are being grabbed "live" from a camera, over a long period of time. I can't wait until all the files are captured before I start writing them to the DVD, I need to write them out in chunks as I go along. I've looked at IMAPI v2, but the main problems seems to be that you need to point it to all the files you plan to write out to disk before you start the burning process. I know it has to concept of "sessions", which means you can write to the DVD in several parts, before you finally "close" it. But I was wondering if there were any other DVD writing SDK's that allow you to be constantly writing files to a DVD and in particular files that are only in memory. It would be more efficient if I didn't have to write the captured images out to hard before they are burned to DVD. The solution needs to work under .NET on Windows XP and vista

  • Grouping Months of a particular Time span together using DateTime.

    - by Calibre2010
    public static string TimeLine2(this HtmlHelper helper, string myString2) { StringBuilder myString3 = new StringBuilder(); DateTime start = new DateTime(2010, 1, 1); DateTime end = new DateTime(2011, 12, 12); myString3.Append("<table>"); myString3.Append("<tr>"); for (DateTime date = start; date <= end; date = date.AddDays(1)) { DayOfWeek dw = date.DayOfWeek; var g = date.Month; var sun = " "; switch (dw) { case DayOfWeek.Sunday: sun = "S"; break; case DayOfWeek.Monday: sun = "M"; break; case DayOfWeek.Tuesday: sun = "T"; break; case DayOfWeek.Wednesday: sun = "W"; break; case DayOfWeek.Thursday: sun = "T"; break; case DayOfWeek.Friday: sun = "F"; break; case DayOfWeek.Saturday: sun = "S"; break; } myString3.Append("<td>" + sun + " " + g + "</td>"); } myString3.Append("</tr>"); myString3.Append("<tr>"); for (DateTime date = start; date <= end; date = date.AddDays(1)) { var f = date.Day; myString3.Append("<td>" + f + "</td>"); } myString3.Append("</tr>"); myString3.Append("</table>"); return myString3.ToString(); } Basically, what I have here is a few loops showing all the days of the week and also all the days in a month. This is all placed inside of a table, so you get MTWTFSSMT W T F S S M M TWTFSSM 12345678910 11 12 13 14 + + to 31 1234567 I'm trying to code a way in which I can split all of these days of the week and days in months so that my code returns each month with all its days in the month and all its days of the week, not just all my months between my timeSpan but splits them so MAY MTWTFSSMTWTFSSMTWTFSSMTWTFSSMTWTF 12345678 JUNE MTWTFSSMTWTFSSMTWTFSSMTWTFSSMTWTF 123456789

  • Getting clusters of rows close together in time

    - by Mike
    I have a table basically like so ID | ItemID | Start | End | --------------------------------------------------------------- 1 234 10/20/09 8:34:22 10/20/09 8:35:10 2 274 10/20/09 8:35:30 10/20/09 8:36:27 3 272 10/21/09 12:15:00 10/21/09 12:17:00 4 112 10/21/09 12:20:14 10/21/09 12:21:21 5 15 10/21/09 12:22:39 10/21/09 12:24:15 There are two "clusters" of entries here, 1-2 and 3-5 separated by a gap in time, specifically 30 minutes is what I'm interested in. What I would like is the first and last rows of the cluster of entries. This is fairly easy to achieve by retrieving all the rows and looping through them in order of start time, but I'd like to have it in SQL if possible. I'm using SQL Server 2008, thanks.

  • Webdav -- GET on a directory

    - by Joe Cannatti
    I am beginning to build a tool that uses WebDAV. I am having trouble wrapping my head around something here. I think I am missing something conceptual. I can use PUT's to add files to the server. I can use GET's to read files from the server, but when I try to use GET on a directory I get a 403:Forbidden. I am using basic authentication. My code in MacRuby is as follows Net::HTTP.start('localhost') do |http| res = Net::HTTP::Get.new('http://localhost/webdav/') res.basic_auth 'jcannatti', 'webdav' http.request res end this returns <Net::HTTPForbidden 403 Forbidden readbody=true> however this Net::HTTP.start('localhost') do |http| res = Net::HTTP::Put.new('http://localhost/webdav/gorilla.txt') res.body = "testetsetest" res.basic_auth 'jcannatti', 'webdav' http.request res end returns <Net::HTTPCreated 201 Created readbody=true> What should happen when calling a GET on a WebDAV directory when everything is working correctly? thanks

  • Video playback on VideoView disappears after going back from another Activity

    - by pixel
    I have two Activities: one with VideoView and the second one. I start watching a video in the first Activity, then during playback I start second Activity. After going back to first Activity I can hear sound but see no picture. My Video Layout: <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent"> <VideoView android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_weight="1" android:id="@+id/videoView" android:layout_gravity="center" /> <ListView android:layout_width="fill_parent" android:layout_height="125dp" android:id="@+id/ListView" /> </LinearLayout> Do you have any ideas why video doesn't appear?

  • Connect to internet with Qt for symbian

    - by Martin
    I'm creating a Qt Symbian application and need to connect to internet. In some way I need to let the user choose a connection when the app starts. I could use Qt Mobility to get it working but when Nokia approves I wan't do publish my application on Ovi Store. As the Qt Mobility is not included in Qt 4.6 it might be a problem to publish my app later. So for this reason I'm thinking of using native APIs instead. The idea is to use: qt_SetDefaultIap() to set the connection on start. I have been looking at this to actually understand what it is doing. If I have two connections that the app could use, one with WIFI and one through mobile internet, which one will qt_SetDefaultIap() choose? And can I in some way with native api make the user choose a connection on start up? (qt_SetDefaultIap seems to just set a default connection on its own, without user choice) Thanks!

  • Confused about using SpringMVC Vs JEE project in Netbeans

    - by Sanju
    Hi all, I want to start a my first JEE project. I have read a lot that springMVC framework is a good choice (never used though) My earlier experience with java is not much. only some small app development using Netbeans. so I have some experience using Netbeans. but I see that I can start a JEE project in Netbeans. so what kind of framework netbeans is using underneath. PS: My understanding of framework (e.g. SpringMVC) is that you follow rule of framework to configure your app. and then framework take care or linking your View, controller and model. so if i am using netbeans, do i need to take care of linking of my MVC by myself?

  • Silence output from SimpleXMLRPCServer

    - by Corey Goldberg
    I am running an xml-rpc server using SimpleXMLRPCServer from the stdlib. My code looks something like this: import SimpleXMLRPCServer import socket class RemoteStarter: def start(self): return 'foo' rs = RemoteStarter() host = socket.gethostbyaddr(socket.gethostname())[0] port = 9000 server = SimpleXMLRPCServer.SimpleXMLRPCServer((host, port)) server.register_instance(rs) server.serve_forever() every time the 'start' method gets called remotely, the server prints an access line like this: <server_name> - - [10/Mar/2010 13:06:20] "POST /RPC2 HTTP/1.0" 200 - I can't figure out a way to silence the output so it doesn't print these access lines to stdout. anyone?

  • Method interception in PHP 5.*

    - by Rolf
    Hi everybody, I'm implementing a Log system for PHP, and I'm a bit stuck. All the configuration is defined in an XML file, that declares every method to be logged. XML is well parsed and converted into a multidimensionnal array (classname = array of methods). So far, so good. Let's take a simple example: #A.php class A { public function foo($bar) { echo ' // Hello there !'; } public function bar($foo) { echo " $ù$ùmezf$z !"; } } #B.php class B { public function far($boo) { echo $boo; } } Now, let's say I've this configuration file: <interceptor> <methods class="__CLASS_DIR__A.php"> <method name="foo"> <log-level>INFO</log-level> <log-message>Transaction init</log-message> </method> </methods> <methods class="__CLASS_DIR__B.php"> <method name="far"> <log-level>DEBUG</log-level> <log-message>Useless</log-message> </method> </methods> </interceptor> The thing I'd like AT RUNTIME ONLY (once the XML parser has done his job) is: #Logger.php (its definitely NOT a final version) -- generated by the XML parser class Logger { public function __call($name,$args) { $log_level = args[0]; $args = array_slice($args,1); switch($method_name) { case 'foo': case 'far': //case ..... //write in log files break; } //THEN, RELAY THE CALL TO THE INITIAL METHOD } } #"dynamic" A.php class A extends Logger { public function foo($log_level, $bar) { echo ' // Hello there !'; } public function bar($foo) { echo " $ù$ùmezf$z !"; } } #"dynamic" B.php class B extends Logger { public function far($log_level, $boo) { echo $boo; } } The big challenge here is to transform A and B into their "dynamic" versions, once the XML parser has completed its job. The ideal would be to achieve that without modifying the code of A and B at all (I mean, in the files) - or at least find a way to come back to their original versions once the program is finished. To be clear, I wanna find the most proper way to intercept method calls in PHP. What are your ideas about it ??? Thanks in advance, Rolf

  • Best way to handle SQL Server fulltext index updates

    - by tlianza
    Hi all, I have a fulltext index which doesn't need to be immediately up-to-date, I'd like to spare myself the I/O (when I do bulk updates, I see a ton of I/O related to the index) and do the index updates during low usage times (nightly, perhaps even weekly). It seems there are two ways to go about this: Turn off change tracking (SET CHANGE_TRACKING OFF) and add a timestamp field to the indexed table, so that you can run alter fulltext index on <table> start INCREMENTAL population, or Enable change tracking, but set it to MANUAL, so that you can run alter fulltext index on <table> start UPDATE population when you need it updated. Is there a preferred method? I couldn't tell from this overview if there was a performance benefit one way or the other. Tom

  • Rails app is prepending tunnlr web address when using link helpers

    - by mathee
    I set up facebooker to tunnel my Ruby on Rails application. The issue is that I would like to test locally. That is, I don't want to have to start a tunnel every time I want to see my changes. Right now, when I start the application using ruby script/server (not calling rake facebooker:tunnel:background_start beforehand), links created by helpers (e.g., stylesheet_link_tag, javascript_include_tag, image_tag) are prepended with my tunnlr address: http://web1.tunnlr.com:myPort/. (For example, a CSS link looks like this in the page source: http://web1.tunnlr.com:myPort//stylesheets/appName.css?1234567890.) I don't want that functionality; I can't see my CSS or JavaScript changes without starting the tunnel first. I want the links to be relative to what's running on my machine, not the tunnel. So, stylesheet_link_tag should produce /stylesheets/appName.css?1234567890. Does anyone know why it's doing that in the first place and how to fix it? Thanks in advance.

  • How to optimize Dijkstra algorithm for a single shortest path between 2 nodes?

    - by Nazgulled
    Hi, I was trying to understand this implementation in C of the Dijkstra algorithm and at the same time modify it so that only the shortest path between 2 specific nodes (source and destination) is found. However, I don't know exactly what do to. The way I see it, there's nothing much to do, I can't seem to change d[] or prev[] cause those arrays aggregate some important data for the shortest path calculation. The only thing I can think of is stopping the algorithm when the path is found, that is, break the cycle when mini = destination when it's being marked as visited. Is there anything else I could do to make it better or is that enough? P.S: I just noticed that the for loops start at 1 until <=, why can't it start at 0 and go until <?
