  • Does binarywriter.flush() also flush the underlying filestream object?

    - by jacob sebastian
    I have got a code snippet as follows: Dim fstream = new filestream(some file here) dim bwriter = new binarywriter(fstream) while not end of file read from source file bwriter.write() bwriter.flush() end while The question I have is the following. When I call bwriter.flush() does it also flush the fstream object? Or should I have to explicitly call fstream.flush() such as given in the following example: while not end of file read from source file bwriter.write() bwriter.flush() fstream.flush() end while A few people suggested that I need to call fstream.flush() explicitly to make sure that the data is written to the disk (or the device). However, my testing shows that the data is written to the disk as soon as I call flush() method on the bwriter object. Can some one confirm this?

  • Why does Google's closure library not use real private members?

    - by Thor Thurn
    I've been a JavaScript developer for a while now, and I've always thought that the correct way to implement private members in JavaScript is to use the technique outlined by Doug Crockford here: http://javascript.crockford.com/private.html. I didn't think this was a particularly controversial piece of JavaScript wisdom, until I started using the Google Closure library. Imagine my surprise... the library makes no effort to use Crockford-style information hiding. All they do is use a special naming convention and note "private" members in the documentation. I'm in the habit of assuming that the guys at Google are usually on the leading edge of software quality, so what gives? Is there some downside to following Mr. Crockford's advice that's not obvious?

  • SQL Server Compact 'Data Directory' macro in Connection String - more info needed

    - by codeulike
    So, as described on this msdn page, when you define a Connection String for SQL Server Compact 3.5, you can use the "Data Directory" macro, like this: quote from this msdn page: Data Directory Support SQL Server Compact 3.5 now supports the Data Directory macro. This means that if you add the string |DataDirectory| (enclosed in pipe symbols) to a file path, it will resolve to the path of the database. For example, consider the connection string: "Data Source= c:\program files\MyApp\Mydb.sdf" When using Data Directory, you can instead use the following connection string: "Data Source = |DataDirectory|\Mydb.sdf" For more information, see How to: Deploy a SQL Server Compact 3.5 Database with an Application. However, the 'for more information' link on msdn doesn't actually give any more information. So my question is: How does the |Data Directory| macro translate at run time? For WinForm apps, it seems to just give the location of the executable. Or is it more complicated than that?

  • Error details in embedded IronPython

    - by Achim
    Hi, I'm executing IronPython in my application. A script produces an UnboundNameException with the message "name 'source' is not defined". Because the script is correct in my opinion I would need more error information, but I'm not able to get them from the exception. The exception itself seems not to contain any information about line number of the source of the exception or something like this. I searched on Google, but all available information seems to be outdated. The Data dictionary of my exception is empty which means that Data["PythonExceptionInfo"] does not exist. The file version of my IronPython assembly is 2.0.20209.0 Any hint how to get more error details? cheers, Achim

  • Find height of ContextMenuStrip before showing it

    - by Nailuj
    I have a ContextMenuStrip (ctMenuMassEdit) that I want to display when left-clicking a button (btnMassEdit). I want the ContextMenuStrip to be displayed above the button, i.e. position (0,-ContextMenuStrip.Height) relative to the button: private void btnMassEdit_Click(object sender, EventArgs e) { ctMenuMassEdit.Show(btnMassEdit, new Point(0, -ctMenuMassEdit.Height)); } However, the Height property is 0 the first time the button is clicked (I assume the ContextMenuStrip isn't created before it is shown the first time), and the result is that the ContextMenuStrip appears on top of the button. The 2nd time I click the button however, it appears in the correct position, so the basic of my logic is at least correct. I tried adding the following before showing the ContextMenuStrip, but it didn't work as hoped: if (!ctMenuMassEdit.Created) { ctMenuMassEdit.CreateControl(); } So, is there a way I can create the ContextMenuStrip before showing it the first time, so I have the correct Height property? I could of course use the hack of showing it, hiding it and showing it again, but that doesn't seem really neat...

  • DNS Problems (NIGHTMARES!) with BIND and Virtualmin

    - by Nyxynyx
    I have a webserver (Ubuntu 12.04 with LAMP) using Virtualmin / Webmin. Because I just moved from a Cpanel system, I am having a nightmare configuring the DNS! Using intoDNS.com, the failed reports are: Mismatched NS records WARNING: One or more of your nameservers did not return any of your NS records. DNS servers responded ERROR: One or more of your nameservers did not respond: The ones that did not respond are: 123.123.123.123 213.251.188.141x Multiple Nameservers ERROR: Looks like you have less than 2 nameservers. According to RFC2182 section 5 you must have at least 3 nameservers, and no more than 7. Having 2 nameservers is also ok by me. Missing nameservers reported by your nameserver You should already know that your NS records at your nameservers are missing, so here it is again: ns1.mydomain.com. sdns2.ovh.net. SOA record No valid SOA record came back! MX Records WWW A Record ERROR: I could not get any A records for www.mydomain.com! Step-by-Step of my Attempt In my domain registrar (Namecheap), I registered ns1.mydomain.com as a nameserver, pointing to the IP address of my web server which is running bind9. The domain is setup with DNS ns1.mydomain.com and sdns2.ovh.net. sdns2.ovh.net is a secondary DNS server (SLAVE and pointing mydomain.com to the IP address of my web server) Webserver domain: mydomain.com Webserver hostname: ns4000000.ip-123-123-123.net Webserver IP: 123.123.123.123 Under Virtualmin, I edited the default Virtual server template, BIND DNS records for new domains: ns1.mydomain.com Master DNS server hostname: ns1.mydomain.com Next I created a Virtual server using that server template. This is what I've done but its still not working! Any ideas?

  • How to keep views free of authorization logic in mvc?

    - by David Lay
    I have a view to display a list of items. The user can edit, delete or create new items, but according to their authorizations they may or may not be allowed to do some of this actions. I have the requirement to display only the actions which the current user is allowed to do, but I don't want to clutter the views with authorization if-else's Despise of being a very common requirement, I can't find a real satisfactory way of doing it. My best approach so far is to provide an overload to the Html.ActionLink extension method that takes the permission to ask for, but there are going to be more complex scenarios, like hiding entire blocks of html or switching a textbox for a label+hidden. Is there a better way to do this?

  • Translate ImageButton from C# to XAML

    - by Bill
    I worked out the C# code to create an ImageButton (below) that has three images (one base-image and two overlays) and three text boxes as the face of the button. I am inheriting from the Button class, which unfortunately includes several components that I didn't realize would surface until after coding and need to remove, namely the bright-blue surrounding border on IsMouseOver, and any visible borders between the buttons, as the buttons will end up in a wrapPanel and the borders need to be seamless. Now that the format has been worked out in C#, I expect that I need to translate to XAML so that I can create a ControlTemplate to get the functionality necessary, however I am not certain as to the process of translating from C# to XAML. Can anyone steer me in the right direction? public class ACover : Button { Image cAImage = null; Image jCImage = null; Image jCImageOverlay = null; TextBlock ATextBlock = null; TextBlock AbTextBlock = null; TextBlock ReleaseDateTextBlock = null; private string _TracksXML = ""; public ACover() { Grid cArtGrid = new Grid(); cArtGrid.Background = new SolidColorBrush(Color.FromRgb(38, 44, 64)); cArtGrid.Margin = new System.Windows.Thickness(5, 10, 5, 10); RowDefinition row1 = new RowDefinition(); row1.Height = new GridLength(225); RowDefinition row2 = new RowDefinition(); row2.Height = new GridLength(0, GridUnitType.Auto); RowDefinition row3 = new RowDefinition(); row3.Height = new GridLength(0, GridUnitType.Auto); RowDefinition row4 = new RowDefinition(); row4.Height = new GridLength(0, GridUnitType.Auto); cArtGrid.RowDefinitions.Add(row1); cArtGrid.RowDefinitions.Add(row2); cArtGrid.RowDefinitions.Add(row3); cArtGrid.RowDefinitions.Add(row4); ColumnDefinition col1 = new ColumnDefinition(); col1.Width = new GridLength(0, GridUnitType.Auto); cArtGrid.ColumnDefinitions.Add(col1); jCImage = new Image(); jCImage.Height = 240; jCImage.Width = 260; jCImage.VerticalAlignment = VerticalAlignment.Top; jCImage.Source = new BitmapImage(new Uri(Properties.Settings.Default.pathToGridImages + "jc.png", UriKind.Absolute)); cArtGrid.Children.Add(jCImage); cArtImage = new Image(); cArtImage.Height = 192; cArtImage.Width = 192; cArtImage.Margin = new System.Windows.Thickness(3, 7, 0, 0); cArtImage.VerticalAlignment = VerticalAlignment.Top; cArtGrid.Children.Add(cArtImage); jCImageOverlay = new Image(); jCImageOverlay.Height = 192; jCImageOverlay.Width = 192; jCImageOverlay.Margin = new System.Windows.Thickness(3, 7, 0, 0); jCImageOverlay.VerticalAlignment = VerticalAlignment.Top; jCImageOverlay.Source = new BitmapImage(new Uri( Properties.Settings.Default.pathToGridImages + "jc-overlay.png", UriKind.Absolute)); coverArtGrid.Children.Add(jCImageOverlay); ATextBlock = new TextBlock(); ATextBlock.Foreground = new SolidColorBrush(Color.FromRgb(173, 176, 198)); ATextBlock.Margin = new Thickness(10, -10, 0, 0); cArtGrid.Children.Add(ATextBlock); AlTextBlock = new TextBlock(); AlTextBlock.Margin = new Thickness(10, 0, 0, 0); AlTextBlock.Foreground = new SolidColorBrush(Color.FromRgb(173, 176, 198)); cArtGrid.Children.Add(AlTextBlock); RDTextBlock = new TextBlock(); RDTextBlock.Margin = new Thickness(10, 0, 0, 0); RDTextBlock.Foreground = new SolidColorBrush(Color.FromRgb(173, 176, 198)); cArtGrid.Children.Add(RDTextBlock); Grid.SetColumn(jCImage, 0); Grid.SetRow(jCImage, 0); Grid.SetColumn(jCImageOverlay, 0); Grid.SetRow(jCImageOverlay, 0); Grid.SetColumn(cArtImage, 0); Grid.SetRow(cArtImage, 0); Grid.SetColumn(ATextBlock, 0); Grid.SetRow(ATextBlock, 1); Grid.SetColumn(AlTextBlock, 0); Grid.SetRow(AlTextBlock, 2); Grid.SetColumn(RDTextBlock, 0); Grid.SetRow(RDTextBlock, 3); this.Content = cArtGrid; } public string A { get { if (ATextBlock != null) return ATextBlock.Text; else return String.Empty; } set { if (ATextBlock != null) ATextBlock.Text = value; } } public string Al { get { if (AlTextBlock != null) return AlTextBlock.Text; else return String.Empty; } set { if (AlTextBlock != null) AlTextBlock.Text = value; } } public string RD { get { if (RDTextBlock != null) return RDTextBlock.Text; else return String.Empty; } set { if (RDTextBlock != null) RDTextBlock.Text = value; } } public ImageSource Image { get { if (cArtImage != null) return cArtImage.Source; else return null; } set { if (cArtImage != null) cArtImage.Source = value; } } public string TracksXML { get { return _TracksXML; } set { _TracksXML = value; } } public double ImageWidth { get { if (cArtImage != null) return cArtImage.Width; else return double.NaN; } set { if (cArtImage != null) cArtImage.Width = value; } } public double ImageHeight { get { if (cArtImage != null) return cArtImage.Height; else return double.NaN; } set { if (cArtImage != null) cArtImage.Height = value; } } }

  • Cufon delay in WordPress, Mac/Safari/FF...

    - by luke
    Using cufon 'manually' not the plugin.... I have a delay on many page loads in Safari and FF on the Cufon enabled headings.... http://www.budewebdesign.com/haf Tried moving Cufon higher up (eg before wp_head() and the plugin code that calls, without any real effect. Some pages no problem but others just a long enough delay to be annoying. I'm not really keen on hiding the headings before the page load completes as is suggested elsewhere. If it loads without delay some of the time, I wonder if it can be made to 'all' of the time :) My connection speed is good. Thanks for any ideas on this.

  • capture flash key event "escape"

    - by P..
    I have a flash site that users can view full Screen video. the trouble is, I am making only the video player full screen (hiding the rest of the site behind it). my "toggle full screen" button works in that it reduces the video player back to normal size when the user toggles out of full screen back. but when the user hits the escape key, my flash script doesn't know that the video player should be reduced in size. it seems there's no way to capture the ESCAPE key as a key event. any ideas?

  • WPF Pass MenuItem selected as MethodParameter to ObjectDataProvider

    I am trying to pass Selected MenuItem's Text/Header string as the MethodParameter to my ObjectDataProvider.

  • Good implementations of reinforced learning?

    - by Paperino
    For an ai-class project I need to implement a reinforcement learning algorithm which beats a simple game of tetris. The game is written in Java and we have the source code. I know the basics of reinforcement learning theory but was wondering if anyone in the SO community had hands on experience with this type of thing. What would your recommended readings be for an implementation of reinforced learning in a tetris game? Are there any good open source projects that accomplish similar things that would be worth checking out? Thanks in advanced Edit: The more specific the better, but general resources about the subject are welcomed. Follow up: Thought it would be nice if I posted a followup. Here's the solution (code and writeup) I ended up with for any future students :). Paper / Code

  • GUI for Build Process

    - by sarah xia
    Hi All, I've just implemented build and deploy process which consists of java files, ant script and cmd files. In the process, a release manager will have to check out source, hit the build.cmd button and then carry a zip file over to a server. I am wondering if it is worthwhile to make a GUI for it? So that the release manager does not need to check out source manually for example? How do I start? I have quite limited knowledge of javax, but I very much like to learn. Thanks, Sarah

  • Changing an extention method from linq-to-sql to entity framework

    - by Jova
    I'm changing my project from working with Linq-to-SQL to working with Entity Framework. I have some extention methods that extend the classes created by LINQ and I'm wondering how to change them to work with the entities instead Here's an example. public static int GetPublishedArticlesCount(this Table<Article> source) { return GetPublishedArticles(source.Context as DataContext, null).Count(); } This method gets the number of published articles. Instead of using this Table<Article>, what should I use instead?

  • Force File Reload Before Build

    - by Byron Ross
    We have a tool that generates some code (.cs) files that are used to build the project. The tool is run during the pre-build step, but the files are updated in the solution only after the build, which means the build needs to be performed twice to clear the errors after a change to the input. Example: Modify Tool Input File Run Build Tool Runs and changes source file Build Fails Run Build Tool Runs and changes source file (but it doesn's actually change, because the input remains the same) Build Succeeds Any ideas how we can do away with the double build, and still let our tool be run from VS? Thanks guys!

  • How to stop flash content shine-through JQuery UI Dialog in FF Windows

    - by DEfusion
    I'm using the jQuery UI dialog box, in IE & FF on Windows I'm getting underlying flash content shining through the dialog box. I resolved this on IE by enabling the bgiframe option on the jQuery dialog window and changing the bgiframe script to apply to any windows browsers, however I'm still getting the shine-through on FF. Note that I can't know exactly where the flash content will be showing as it is usually flash widgets that users have added to pages, although I have thought about hiding the flash content temporarily while displaying the dialog box - is this the only option left to me?

  • Linq Query Help Needed

    - by Randy Minder
    Say I have the following LINQ queries: var source = from workflow in sourceWorkflowList select new { SubID = workflow.SubID, ReadTime = workflow.ReadTime, ProcessID = workflow.ProcessID, LineID = workflow.LineID }; var target = from workflow in targetWorkflowList select new { SubID = workflow.SubID, ReadTime = workflow.ReadTime, ProcessID = workflow.ProcessID, LineID = workflow.LineID }; var difference = source.Except(target); sourceWorkflowList and targetWorkflowList have the exact same column definitions. But they both contain more columns of data than what is shown in the queries above. Those are just the columns needed for this particular issue. difference contains all rows in sourceWorkflowList that are not contained in targetWorkflowList Now what I would like to do is to remove all rows from sourceWorkflowList that do not exist in difference. Could someone show me a query that would do this? Thanks very much - Randy

  • How can a component at designtime determine the project directory

    - by Heinz Z.
    Hello, I write a component which should store some information relative to the project directory. Every time a property of my component is changed it should write a file. So how can a component determine the current project directory at design time. Thanks in advance EDIT: I want to generate a delphi source file every time a property of my component is changed, so that I always get the latest version when I compile my code. Think of it as a kind of code generator. At the moment I set whole path and filename where the source should be stored but I prefer a relative path to the project (or the form/datamodule which contains my component) to make it easier to copy the project on different developer machines.

  • Uses of Erlang in Telecom

    - by user94154
    I'm a web developer and a college student majoring in telecommunications. This means I'm decent at programming and I know a little about telecom networks (at a high, non-technical level). I keep reading that Erlang is used all over the telecom industry (supposedly for its performance). I'm wondering if there's anyway I can combine my programming skills with my telecommunications major with Erlang. Is most of the Erlang/telecom stuff closed source? Are there any open source telecom projects written Erlang? UPDATE: sipwiz's comment makes me think in terms of a question larger than "uses of Erlang". How can I leverage a high-level understanding of telecom networks and the telecom regulatory environment with programming. I hope this hasn't veered too off-topic for SO.

  • Grid View Pagination.

    - by Wondering
    Dear All, I have a grid view and I want to implement Pagination functionality.This is working fine. protected DataSet FillDataSet() { string source = "Database=GridTest;Server=Localhost;Trusted_Connection=yes"; con = new SqlConnection(source); cmd = new SqlCommand("proc_mygrid", con); ds = new DataSet(); da = new SqlDataAdapter(cmd); da.Fill(ds); GridView1.DataSource = ds; GridView1.DataBind(); return ds; } protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e) { int newPagenumber = e.NewPageIndex; GridView1.PageIndex = newPagenumber; GridView1.DataSource = FillDataSet(); GridView1.DataBind(); } But the problem is for each pagination I have to call FillDataSet(); Is there any way to stop that.Any other coding approach? Thanks.

  • UIView Subview Does not autoresize on orientation change

    - by Jason
    In my iPhone app, I have a view controller with two views (essentially, a front & back view). The front view is the main UIView, and the back view is a secondary UIView which is added as a subview using [self.view addSubview:backView] when showing the back and [backView removeFromSuperview] when hiding it. However, when the orientation changes, I have the following issue: the main UIView (frontView) rotates & all of its elements resize properly, but the secondary/subview UIView (backView) does not rotate & all of its elements do not resize properly. Does anyone have suggestions on how to make the secondary UIView autoresize properly according to the rules I have set in Interface Builder?

  • bat file using winrar taking too long to run

    - by Jessie
    hi guys, i have this scripts which extracts all my folder's and files from my c:\projects locations and put its in winrar and transfers them to c:\backup\project for /f "delims==" %%D in ('DIR C:\projects /A /B /S') do ( "C:\Program Files\WinRAR\WinRAR.EXE" m -r "c:\backup\projects.rar" "%%D" ) i have also tried the below script which uses the same source c:\projects but put them in their own separate winrar folder like in the source then transfers the folders into my c:\backup. FOR /F "DELIMS==" %%D in ('DIR C:\projects /AD /B') DO ( "C:\Program Files\WinRAR\WinRAR.EXE" m -r "C:\Backup\%%D.rar" "%%D" ) my question is, my second scripts only takes two hours to run when my first script takes over 24 hours to run, is there any way to make my first script faster? if anything shouldn't my first script be faster?
