  • How to connect to SqlExpress for Entity Framework using Visual Studio 2010 Express?

    - by Mike
    Hi everyone, I'm trying to use the Visual Studio 2010 Express editions to set up an ASP.NET MVC 2 Web Application using SqlExpress + Entity Framework as the data access. I have both the "C# Edition" and "Web Developer Edition" installed. If I try to add a data source using the "C# edition", I'm missing the "Microsoft SQL Server" data source type. but Visual Studio 2008 Professional has it. as noted by another StackOverflow question, the "Web Developer Edition" has this. However, the Web Developer Edition doesn't support the Entity Framework items: . I'd want to stick with only the Express Editions. Is my use case one that Microsoft forgot about? What can I do here to use SqlExpress + MVC 2 + Entity Framework? Thanks! -Mike

  • Transforming TT files in MsBuild

    - by Phill Duffy
    I need to build a DSL Solution using MsBuild and want to be able to transform the TT files, I have tried the guide on http://msdn.microsoft.com/en-us/library/ee847423(VS.100).aspx but I am getting the following errors: Failed to resolve include text for file:{0} and also Loading the include file '{0}' returned a null or empty string. There is a page on MSDN which has these issues and there resolutions : http://msdn.microsoft.com/en-us/library/bb126242(VS.100).aspx but don't really give me enough information to resolve the issue. One thing to note in the error it has the following path: Error 72 Failed to resolve include text for file:C:\source\XXXXXXXX\Dsl\GeneratedCode\Dsl\ToolboxHelper.tt.

  • Microsoft Team Foundation Equivalent stack.

    - by Nix
    I am looking for a free alternative to TFS. What would be the best alternative stack(source control, bug tracking, project management/planning, wiki, automated builds (ci))? Keeping in mind that it would be nice if they all integrated well. For example, it would be nice to be able to link bugs to source control, and then be able to link to a project plan and then be able to automate building. I do not have issues with using Microsoft project to manage project planing. I know i would like to use these....: SVN TeamCity NUnit But i am struggling to find a good Wiki/Project Planning/Bug tracking, that would integrate well. Any questions let me know.

  • How to Use the Signature Editor in Outlook 2013

    - by Lori Kaufman
    The Signature Editor in Outlook 2013 allows you to create a custom signature from text, graphics, or business cards. We will show you how to use the various features of the Signature Editor to customize your signatures. To open the Signature Editor, click the File tab and select Options on the left side of the Account Information screen. Then, click Mail on the left side of the Options dialog box and click the Signatures button. For more details, refer to one of the articles mentioned above. Changing the font for your signature is pretty self-explanatory. Select the text for which you want to change the font and select the desired font from the drop-down list. You can also set the justification (left, center, right) for each line of text separately. The drop-down list that reads Automatic by default allows you to change the color of the selected text. Click OK to accept your changes and close the Signatures and Stationery dialog box. To see your signature in an email, click Mail on the Navigation Bar. Click New Email on the Home tab. The Message window displays and your default signature is inserted into the body of the email. NOTE: You shouldn’t use fonts that are not common in your signatures. In order for the recipient to see your signature as you intended, the font you choose also needs to be installed on the recipient’s computer. If the font is not installed, the recipient would see a different font, the wrong characters, or even placeholder characters, which are empty square boxes. Close the Message window using the File tab or the X button in the upper, right corner of the Message window. You can save it as a draft if you want, but it’s not necessary. If you decide to use a font that is not common, a better way to do so would be to create a signature as an image, or logo. Create your image or logo in an image editing program making it the exact size you want to use in your signature. Save the image in a file size as small as possible. The .jpg format works well for pictures, the .png format works well for detailed graphics, and the .gif format works well for simple graphics. The .gif format generally produces the smallest files. To insert an image in your signature, open the Signatures and Stationery dialog box again. Either delete the text currently in the editor, if any, or create a new signature. Then, click the image button on the editor’s toolbar. On the Insert Picture dialog box, navigate to the location of your image, select the file, and click Insert. If you want to insert an image from the web, you must enter the full URL for the image in the File name edit box (instead of the local image filename). For example, http://www.somedomain.com/images/signaturepic.gif. If you want to link to the image at the specified URL, you must also select Link to File from the Insert drop-down list to maintain the URL reference. The image is inserted into the Edit signature box. Click OK to accept your changes and close the Signatures and Stationery dialog box. Create a new email message again. You’ll notice the image you inserted into the signature displays in the body of the message. Close the Message window using the File tab or the X button in the upper, right corner of the Message window. You may want to put a link to a webpage or an email link in your signature. To do this, open the Signatures and Stationery dialog box again. Enter the text to display for the link, highlight the text, and click the Hyperlink button on the editor’s toolbar. On the Insert Hyperlink dialog box, select the type of link from the list on the left and enter the webpage, email, or other type of address in the Address edit box. You can change the text that will display in the signature for the link in the Text to display edit box. Click OK to accept your changes and close the dialog box. The link displays in the editor with the default blue, underlined text. Click OK to accept your changes and close the Signatures and Stationery dialog box. Here’s an example of an email message with a link in the signature. Close the Message window using the File tab or the X button in the upper, right corner of the Message window. You can also insert your contact information into your signature as a Business Card. To do so, click Business Card on the editor’s toolbar. On the Insert Business Card dialog box, select the contact you want to insert as a Business Card. Select a size for the Business Card image from the Size drop-down list. Click OK. The Business Card image displays in the Signature Editor. Click OK to accept your changes and close the Signatures and Stationery dialog box. When you insert a Business Card into your signature, the Business Card image displays in the body of the email message and a .vcf file containing your contact information is attached to the email. This .vcf file can be imported into programs like Outlook that support this format. Close the Message window using the File tab or the X button in the upper, right corner of the Message window. You can also insert your Business Card into your signature without the image or without the .vcf file attached. If you want to provide recipients your contact info in a .vcf file, but don’t want to attach it to every email, you can upload the .vcf file to a location on the internet and add a link to the file, such as “Get my vCard,” in your signature. NOTE: If you want to edit your business card, such as applying a different template to it, you must select a different View other than People for your Contacts folder so you can open the full contact editing window.

  • How to determine if a file will be logically moved or physically moved.

    - by Frederic Morin
    The facts: When a file is moved, there's two possibilities: The source and destination file are on the same partition and only the file system index is updated The source and destination are on two different file system and the file need to be moved byte per byte. (aka copy on move) The question: How can I determine if a file will be either logically or physically moved ? I'm transferring large files (700+ megs) and would adopt a different behaviors for each situation. Edit: I've already coded a moving file dialog with a worker thread that perform the blocking io call to copy the file a meg at a time. It provide information to the user like rough estimate of the remaining time and transfer rate. The problem is: how do I know if the file can be moved logically before trying to move it physically ?

  • how to souce a csh script in bash to set the enviroment

    - by Daniel
    We have oracle running on Solaris, and the shell is by default CSH. So the login script set the oracle_home,oracle_sid in csh also. But I don't like csh and want to use bash to do my work. So how to source the csh login script in bash? e.g, the following is what in the .cshrc file. And when use bash, I'd like use these variables. One way is to copy the variables again and use bash command, such as export ORACLE_SID=TEST. But doing so will let us to maintain two copy of the files. And when we change the database name, or upgrade the database, I need to maintian the bash login file seperately. It's nice to just use something like source .cshr in bash, but it doesn't work. setenv ORACLE_SID TEST setenv ORACLE_HOME /oracle/TEST/home/products/10204 setenv EPC_DISABLED TRUE setenv MANPATH /usr/local/man:/usr/share/man setenv EDITOR vi setenv LD_LIBRARY_PATH $ORACLE_HOME/lib:/usr/sfw/lib/64 setenv NLS_LANG AMERICAN_AMERICA.UTF8 setenv NLS_DATE_FORMAT "DD-MON-RR"

  • Microsoft Quotation

    - by Asad Jibran Ahmed
    I don't know if this is the right place to ask this question, but I honestly have exhausted my self searching for the last hour. I am looking for a quotation made about Microsofts software. It goes something along the lines of: "They may make 2nd grade crappy software, but by God they know how to design interfaces" It was by a somewhat popular open source personality about the lack of good interface design in open source software. Does any one know the exact quotation? It will be a great help if someone can point me in the right direction.

  • Problems with CGI wrapper for PHP

    - by user205878
    I'm having a bugger of a time with a CGI wrapper for PHP. I know very little about CGI and PHP as CGI. Here's what I know about the system: Solaris 10 on a 386 Suhosin PHP normally running as CGI, with cgiwrap (http://cgiwrap.sourceforge.net/). I am not able to find an example wrapper.cgi on the server to look at. Shared hosting (virtual host), so I don't have access to Apache config. But the admins are not helpful. Switching hosts is not an option. Options directive cannot be overridden in .htaccess (ExecCGI, for example). .htaccess: AddHandler php-handler .php Action php-handler "/bin/test.cgi" ~/public_html/bin/test.cgi: #!/usr/bin/sh # Without these 2 lines, I get an Internal Server Error echo "Content-type: text/html" echo "" exec "/path/to/php-cgi" 'foo.php'; /bin/foo.php: <?php echo "this is foo.php!"; Output of http://mysite.com/bin/test.cgi: X-Powered-By: PHP/5.2.11 Content-type: text/html echo "Content-type: text/html" echo "" exec "/path/to//php-cgi" 'foo.php'; Output of http:/ /mysite.com/anypage.php: X-Powered-By: PHP/5.2.11 Content-type: text/html echo "Content-type: text/html" echo "" exec "/path/to//php-cgi" 'foo.php'; The things I note are: PHP is being executed, as noted by the X-Powered-By ... header. The source of /bin/test.cgi is output in the results. No matter what I put as the second argument of exec, it isn't passed to the php binary. I've tried '-i' to get phpinfo, '-v' to get the version... When I execute test.cgi via the shell, I get the expected results (the argument is passed to php, and it is reflected in the output). Any ideas about how to get this to work? UPDATE It appears that the reason the source of the test.cgi was appearing was due to errors. Anytime fatal error occurred, either within the cgi itself or with the command being executed by exec, it would cause the source of the cgi to appear. Within test.cgi, I can get the proper output with exec "/path/to/php-cgi" -h (I get the same thing as I would from CLI).

  • How can I copy files with timestamps between 2 times and preserve the directory structure

    - by brushwood
    I want to copy files that have timestamps from the time the script begins to run and a hour previous. So I am basically trying to emulate robocopy but with minage and maxage going down to the exact time rather than days. So far I have this in powershell: $now = Get-Date $previousHour = $now.AddHours(-1) "Copying files from $previousHour to $now" function DoCopy ($source, $destination) { $fileList = gci $source -Recurse foreach ($file in $fileList) { if($file.LastWriteTime -lt $now -and $file.LastWriteTime -gt $previousHour) { #Do the copy } } } DoCopy "C:\test" "C:\test2" but if I try to do the copy like that, it copies all the files directly into the destination folder rather than the subfolders.enter code here

  • Programmatic use of ARP

    - by sizzzzlerz
    I have a need for some C or C++ code, compilable under Linux, to be able to take a list of IP addresses of some arbitrary number of remote hosts machines and obtain a ethernet MAC address for each one. These host machines may be on the same subnet or they could be on a different subnet behind a router. Its OK if the MAC address of some or all of the remote hosts is the address of the interface on the router. Ultimately, I want to hand off the IP address and MAC address to an FPGA who will use these pieces of information to format and send UDP/IP packets over ethernet to the hosts. Obviously, the FPGA will also be given its own MAC address and IP address to fill in the source MAC and source IP addresses in the packets. Is there some code I can be pointed to that can create and broadcast ARP packets to these remote machines and receive back the ARP response packets such that the destination MAC addresses can be extracted?

  • NSZombieEnabled breaking working code?

    - by Gordon Fontenot
    I have the following method in UIImageManipulation.m: +(UIImage *)scaleImage:(UIImage *)source toSize:(CGSize)size { UIImage *scaledImage = nil; if (source != nil) { UIGraphicsBeginImageContext(size); [source drawInRect:CGRectMake(0, 0, size.width, size.height)]; scaledImage = UIGraphicsGetImageFromCurrentImageContext(); UIGraphicsEndImageContext(); } return scaledImage; } I am calling it in a different view with: imageFromFile = [UIImageManipulator scaleImage:imageFromFile toSize:imageView.frame.size]; (imageView is a UIImageView allocated earlier) This is working great in my code. I resizes the image perfectly, and throws zero errors. I also don't have anything pop up under build - analyze. But the second I turn on NSZombieEnabled to debug a different EXC_BAD_ACCESS issue, the code breaks. Every single time. I can turn NSZombieEnabled off, code runs great. I turn it on, and boom. Broken. I comment out the call, and it works again. Every single time, it gives me an error in the console: -[UIImage release]: message sent to deallocated instance 0x3b1d600. This error doesn't appear if `NSZombieEnabled is turned off. Any ideas? --EDIT-- Ok, This is killing me. I have stuck breakpoints everywhere I can, and I still cannot get a hold of this thing. Here is the full code when I call the scaleImage method: -(void)setupImageButton { UIImage *imageFromFile; if (object.imageAttribute == nil) { imageFromFile = [UIImage imageNamed:@"no-image.png"]; } else { imageFromFile = object.imageAttribute; } UIImage *scaledImage = [UIImageManipulator scaleImage:imageFromFile toSize:imageButton.frame.size]; UIImage *roundedImage = [UIImageManipulator makeRoundCornerImage:scaledImage :10 :10 withBorder:YES]; [imageButton setBackgroundImage:roundedImage forState:UIControlStateNormal]; } The other UIImageManipulator method (makeRoundCornerImage) shouldn't be causing the error, but just in case I'm overlooking something, I threw the entire file up on github here. It's something about this method though. Has to be. If I comment it out, it works great. If I leave it in, Error. But it doesn't throw errors with NSZombieEnabled turned off ever.

    I have two databases (SQL Server 2005) with the same table schemes. I need to copy data from source table to destination with some modification of data along the way. And if destination table already contains some data, then rows from source table should not override, but be added to the destination table. In our project we use LLBLGen and LINQ to LLBLGen to as ORM solution.

  • How to get full control of umask/PAM/permissions?

    - by plua
    OUR SITUATION Several people from our company log in to a server and upload files. They all need to be able to upload and overwrite the same files. They have different usernames, but are all part of the same group. However, this is an internet server, so the "other" users should have (in general) just read-only access. So what I want to have is these standard permissions: files: 664 directories: 771 My goal is that all users do not need to worry about permissions. The server should be configured in such a way that these permissions apply to all files and directories, newly created, copied, or over-written. Only when we need some special permissions we'd manually change this. We upload files to the server by SFTP-ing in Nautilus, by mounting the server using sshfs and accessing it in Nautilus as if it were a local folder, and by SCP-ing in the command line. That basically covers our situation and what we aim to do. Now, I have read many things about the beautiful umask functionality. From what I understand umask (together with PAM) should allow me to do exactly what I want: set standard permissions for new files and directories. However, after many many hours of reading and trial-and-error, I still do not get this to work. I get many unexpected results. I really like to get a solid grasp of umask and have many question unanswered. I will post these questions below, together with my findings and an explanation of my trials that led to these questions. Given that many things appear to go wrong, I think that I am doing several things wrong. So therefore, there are many questions. NOTE: I am using Ubuntu 9.10 and therefore can not change the sshd_config to set the umask for the SFTP server. Installed SSH OpenSSH_5.1p1 Debian-6ubuntu2 < required OpenSSH 5.4p1. So here go the questions. 1. DO I NEED TO RESTART FOR PAM CHANGS TO TAKE EFFECT? Let's start with this. There were so many files involved and I was unable to figure out what does and what does not affect things, also because I did not know whether or not I have to restart the whole system for PAM changes to take effect. I did do so after not seeing the expected results, but is this really necessary? Or can I just log out from the server and log back in, and should new PAM policies be effective? Or is there some 'PAM' program to reload? 2. IS THERE ONE SINGLE FILE TO CHANGE THAT AFFECTS ALL USERS FOR ALL SESSIONS? So I ended up changing MANY files, as I read MANY different things. I ended up setting the umask in the following files: ~/.profile -> umask=0002 ~/.bashrc -> umask=0002 /etc/profile -> umask=0002 /etc/pam.d/common-session -> umask=0002 /etc/pam.d/sshd -> umask=0002 /etc/pam.d/login -> umask=0002 I want this change to apply to all users, so some sort of system-wide change would be best. Can it be achieved? 3. AFTER ALL, THIS UMASK THING, DOES IT WORK? So after changing umask to 0002 at every possible place, I run tests. ------------SCP----------- TEST 1: scp testfile (which has 777 permissions for testing purposes) server:/home/ testfile 100% 4 0.0KB/s 00:00 Let's check permissions: user@server:/home$ ls -l total 4 -rwx--x--x 1 user uploaders 4 2011-02-05 17:59 testfile (711) ---------SSH------------ TEST 2: ssh server user@server:/home$ touch anotherfile user@server:/home$ ls -l total 4 -rw-rw-r-- 1 user uploaders 0 2011-02-05 18:03 anotherfile (664) --------SFTP----------- Nautilus: sftp://server/home/ Copy and paste newfile from client to server (777 on client) TEST 3: user@server:/home$ ls -l total 4 -rwxrwxrwx 1 user uploaders 3 2011-02-05 18:05 newfile (777) Create a new file through Nautilus. Check file permissions in terminal: TEST 4: user@server:/home$ ls -l total 4 -rw------- 1 user uploaders 0 2011-02-05 18:06 newfile (600) I mean... WHAT just happened here?! We should get 644 every single time. Instead I get 711, 777, 600, and then once 644. And the 644 is only achieved when creating a new, blank file through SSH, which is the least probable scenario. So I am asking, does umask/pam work after all? 4. SO WHAT DOES IT MEAN TO UMASK SSHFS? Sometimes we mount a server locally, using sshfs. Very useful. But again, we have permissions issues. Here is how we mount: sshfs -o idmap=user -o umask=0113 user@server:/home/ /mnt NOTE: we use umask = 113 because apparently, sshfs starts from 777 instead of 666, so with 113 we get 664 which is the desired file permission. But what now happens is that we see all files and directories as if they are 664. We browse in Nautilus to /mnt and: Right click - New File (newfile) --- TEST 5 Right click - New Folder (newfolder) --- TEST 6 Copy and paste a 777 file from our local client --- TEST 7 So let's check on the command line: user@client:/mnt$ ls -l total 8 -rw-rw-r-- 1 user 1007 3 Feb 5 18:05 copyfile (664) -rw-rw-r-- 1 user 1007 0 Feb 5 18:15 newfile (664) drw-rw-r-- 1 user 1007 4096 Feb 5 18:15 newfolder (664) But hey, let's check this same folder on the server-side: user@server:/home$ ls -l total 8 -rwxrwxrwx 1 user uploaders 3 2011-02-05 18:05 copyfile (777) -rw------- 1 user uploaders 0 2011-02-05 18:15 newfile (600) drwx--x--x 2 user uploaders 4096 2011-02-05 18:15 newfolder (711) What?! The REAL file permissions are very different from what we see in Nautilus. So does this umask on sshfs just create a 'filter' that shows unreal file permissions? And I tried to open a file from another user but the same group that had real 600 permissions but 644 'fake' permissions, and I could still not read this, so what good is this filter?? 5. UMASK IS ALL ABOUT FILES. BUT WHAT ABOUT DIRECTORIES? From my tests I can see that the umask that is being applied also somehow influences the directory permissions. However, I want my files to be 664 (002) and my directories to be 771 (006). So is it possible to have a different umask for directories? 6. PERHAPS UMASK/PAM IS REALLY COOL, BUT UBUNTU IS JUST BUGGY? On the one hand, I have read topics of people that have had success with PAM/UMASK and Ubuntu. On the other hand, I have found many older and newer bugs regarding umask/PAM/fuse on Ubuntu: https://bugs.launchpad.net/ubuntu/+source/gdm/+bug/241198 https://bugs.launchpad.net/ubuntu/+source/fuse/+bug/239792 https://bugs.launchpad.net/ubuntu/+source/pam/+bug/253096 https://bugs.launchpad.net/ubuntu/+source/sudo/+bug/549172 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=314796 So I do not know what to believe anymore. Should I just give up? Would ACL solve all my problems? Or do I have again problems using Ubuntu? One word of caution with backups using tar. Red Hat /Centos distributions support acls in the tar program but Ubuntu does not support acls when backing up. This means that all acls will be lost when you create a backup. I am very willing to upgrade to Ubuntu 10.04 if that would solve my problems too, but first I want to understand what is happening.

  • Inferring using Jena

    - by Mikae Combarado
    InfModel infmodel = ModelFactory.createInfModel(reasoner, m); Resource vegetarian = infmodel.getResource(source + "Vegetarian"); Resource margherita = infmodel.getResource(source + "Example-Margherita"); if (infmodel.contains(margherita, RDF., vegetarian)) { System.out.println("Margherita is a memberOf Vegetarian pizza"); } The example given above is formed by formal pizza.owl. In this owl, Example-Margherita is an individual of Margherita class. So, it is already written in owl file. However, the problem is that the reasoner should infer that margherita-example should be also an vegetarian pizza. Could anyone please give an example that shows how to find an individual's possible inferred classes like in Protege ?(Protege correctly infers that Example-Margherita is a Vegetarian Pizza. However, I can't infer programmatically)

  • 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; } } }

  • 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?
