  • PrintingPermissionLevel, SafePrinting, and restrictions

    - by Steve Cooper
    There is a PrintingPermission attribute in the framework which takes a PrintingPermissionLevel enumeration with one of these values; NoPrinting: Prevents access to printers. NoPrinting is a subset of SafePrinting. SafePrinting: Provides printing only from a restricted dialog box. SafePrinting is a subset of DefaultPrinting. DefaultPrinting: Provides printing programmatically to the default printer, along with safe printing through semirestricted dialog box. DefaultPrinting is a subset of AllPrinting. AllPrinting: Provides full access to all printers. The documentation is really sparse, and I wondered if anyone can tell me more about the SafePrinting option. What does the documentation mean when it says "Provides printing only from a restricted dialog box." I have no idea what this means. Can anyone shed any light? This subject is touched in the MS certification 70-505: TS: Microsoft .NET Framework 3.5, Windows Forms Application Development and so I'm keen to find out more.

  • Create a modifiable string literal in C++

    - by Anne
    Is it possible to create a modifiable string literal in C++? For example: char* foo[] = { "foo", "foo" }; char* afoo = foo[0]; afoo[2] = 'g'; // access violation This produces an access violation because the "foo"s are allocated in read only memory (.rdata section I believe). Is there any way to force the "foo"s into writable memory (.data section)? Even via a pragma would be acceptable! (Visual Studio compiler) I know I can do strdup and a number of other things to get around the problem, but I want to know specifically if I can do as I have asked. :)

  • What is the best strategy for a streaming screen capture application ?

    - by The_AlienCoder
    Ok Ive figured out how to do a screen capture of my desktop using Windows Media Encoder 9 + SDK and saving it as a movie on my hardrive. But now I want to take my project further and stream a realtime screen capture of my desktop . The idea is that users accessing my asp.net website will be able to view whatever Im doing on my desktop in real time via the video streaming from my computer. I really dont need the source code just the best strategy, procedure and server requirements.How will users access the streaming video on my website? Will it work on my godaddy shared hosting account or at what point will I need an upgrade? Will I be saving the stream to a file on the server for users to access or is there a way to stream directly ? I just need someone to point me in the right direction...

  • Mount remote drive by port forwarding

    - by Anushka
    I have a windows 7 computer at home and a remote windows XP machine with an external USB drive attached to it. I would like to be able to copy files to and from home/the remote USB drive. The problem is that the only way of contacting the work computer is by first sshing into a different remote linux machine as there is a firewall that prevents direct internet connection. I can see two possible solutions but I don't know how to do them. Set up winscp using ssh port forwarding via the linux box so that I can copy to and from the two windows machines. I assume that I would need to run an ssh server on the XP machine as well to do this? Mounting the remote USB drive on the remote windows machine from the home XP machine via ssh port forwarding again via the linux box. Does anyone know how to do either solution?

  • DB management for Heroku apps

    - by zetarun
    Hi all, I'm fairly new to both Rails and Heroku but I'm seriously thinking of using it as a platform to deploy my Ruby/Rails applications. I want to use all the power of Heroku, so I prefer the "embedded" PostgreSQL managed by Heroku instead of the addon for Amazon RDS for MySQL, but I'm not so confident without the possibility to access my data in a SQL client... I know that in a well made app you have no need to access DB, but there are some situations (add rows to a config table, see data not mapped in a view, update some columns for debugging issues, performance monitoring, running queries for reporting, etc.) when this can be good... How do you solve this problem? What's you experience in a real life app powered by Heroku? Thanks!

  • PHP and Java interoperablity

    - by Jack
    I am working on windows using tomcat 6 and PHP/Java Bridge. I know how to access a Java file from PHP but how do we do it the other way i.e accessing PHP from Java <?php require_once("java\Java.inc"); $systemInfo = new Java("java.lang.System"); print "Total seconds since January 1, 1970: ".$systemInfo->currentTimeMillis(); ?> Also how do I access Java classes that are created by me. Do I write a CLASSPATH env variable or change the php.ini config file?

  • which MVC for coldfusion?

    - by mrjayviper
    newbie to MVC here. so please be gentle. I want to move one of our existing apps (currently located in http://www.companywebsitegoeshere.com/myapp1) to MVC. As can be seen in the URL, there are many apps running in the website which I intend to move at some stage. I don't have write access to the wwwroot (/var/www/html in my case) and the webserver is used by multiple developers across the company. I'm hoping I can have the MVC framework core files/folders + my app all located in in 1 subfolder. In the case of myapp1, all the filers and folders will be inside /var/www/html/myapp1 subfolder. Can you please point me to the right direction (links/guides/docs/videos/etc)? I've looked at several like cfwheels/mach-ii/fw1 but they seemed requires wwwroot access. Thanks! :)

  • Does a dedicated video card improve HTML5 websites, Skype or Flash games performance?

    - by Kiewic
    I have read that having a dedicated video card (GPU) improves performance if you use your computer to play video games. I guess to make this happen, video games or apps must be using especial libraries designed to share the workload with the GPU, maybe Direct X or OpenGL, I don't know. Am I wrong? So, can HTML5 websites, Adobe Illustrator, Flash games (Zynga games), Skype or Netflix benefit from a dedicated video card? I usually do the previous activities simultaneously. Should I consider changing from an integrated video card to a dedicated card if I want to improve performance? Thanks.

  • Is there an equivalent to C++'s "friend class" in Java?

    - by Ricket
    In C++ there is a concept of a "friend", which has access to a class's private variables and functions. So if you have: class Foo { friend class Bar; private: int x; } then any instance of the class Bar can modify any Foo instance's x member, despite it being private, because Bar is a friend of Foo. Now I have a situation in Java where this functionality would come in handy. There are three classes: Database, Modifier, Viewer. The Database is just a collection of variables (like a struct). Modifier should be "friends" with Database; that is, it should be able to read and write its variables directly. But Viewer should only be able to read Database's variables. How is this best implemented? Is there a good way to enforce Viewer's read-only access of Database?

  • Crash when checking BOF property of pessimistic locked ADO recordset

    - by Patrick
    Bit of an odd one for you: I've got two connections to a database, on one I've opened a _RecordsetPtr with a pessimistic lock. I can no longer send an UPDATE command on the other connection. I can send a SELECT command on the second connection and data is returned. If I use a read only lock then there are no problems however when I use a pessimistic lock on the second connection as well I can check the State == adStateOpen but the program hangs when I test the BOF property! If I don't test the BOF property and try to call moveNext on the second connection the software hangs If I do neither of these I am able to access the data via the second connection but trying to access the data from the first connection causes the software to hang. Any one seen anything similar as I'm a bit stuck? EDIT : it wasn't hanging, someone had put a 30 minute timeout on the connection and I wasn't waiting that long while testing...

  • "private" directory not accessible in Apache

    - by janeden
    The directory private lives under my DocumentRoot, and despite its name, it should be accessible just like any other dir. But if I add the following RewriteRule to httpd.conf: RewriteRule ^/([^\.]+)$ /$1.html [L] Apache returns 403 for http://server/private/2201. The error log states client denied by server configuration: /private/2201.html If I then rename private to foo, or if I request 2201.html directly, the file is served: 127.0.0.1 - - [21/Nov/2011:10:24:45 +0100] "GET /private/2201 HTTP/1.1" 403 214 127.0.0.1 - - [21/Nov/2011:10:24:58 +0100] "GET /foo/2201 HTTP/1.1" 200 3068 127.0.0.1 - - [21/Nov/2011:10:27:39 +0100] "GET /private/2201.html HTTP/1.1" 200 3068 This is confusing. Is there any special rule for directories named private? If so – why does the direct request for 2201.html work (although the denied request seems to handle the same resource, at least according to the error log entry)?

  • How to run a command in a process that is not a child of the current process?

    - by amicitas
    I am having a library conflict issue with calling an external program from within a interpreted programming environment (IDL). The issue seems to be that since the program I am calling ends up as a child of IDL, libraries are not being reloaded. From within IDL I can launch sub-processes either directly or using a shell. Is there a good way that I can cause my program to be run without ending up as a child process? The only solution I have found so far is to use ssh localhost my_program. This works perfectly but I would like a more direct solution.

  • Chromium never stops loading iGoogle

    - by regulatethis
    I almost always keep a tab open on google.com/ig. Recently I've noticed that the "loading" animation for that tab never stops spinning, even though the page appears to be fully loaded. Even though there's no direct problem with this, I find the animation really distracting and to be honest it's driving me crazy. I've done a few things to try to figure this out. I've removed every single one of my gadgets (so my igoogle is blank), but that made no difference. I've disabled adblock and scriptno. nothing. I've watched the network console in developer tools to look for resources that haven't finished loading, but it looks like everything is done. I'm all out of ideas. For my sanity's sake, please help.

  • Netgear routers don't allow you to disable wireless admin??

    - by MousePad
    I just bought a new router, the NetGear WGR614. Nowhere in the settings can you disable the ability to administrate the router from a wireless connection, which opens it up to brute force attacks from outside the building. Furthermore, it doesn't require a direct connection to the router to admin either, you can admin it while you're connected to the Internet. This means it opens itself to the possibility of an attack from within the network. This is unbelievable to me. What am I missing? Can this be possible?

  • Adding a Jar to ext and using it in Eclipse

    - by Bob Breznak
    I am providing a client with a lab station image for a school program. There is a library that I'd like to directly add to the JRE so that students can use the library without needing to fiddle with adding the classpath. As this is a basic after school program, the goal is to just get students into programming with as little overhead additions as possible. At this point, I have the lib put into the jre/lib/ext and Eclipse is able to find it, however it will not allow access to any of the classes. I see it in the JRE System Library and the classes and packages are showing up there but when I go to use it, I am getting an "Access restriction" error. When I remove the JRE System Library then add it back in, everything works swimmingly. The library is accessible exactly as intended. Any ideas on how to resolve this?

  • Why does 'dd' not work for creating bootable USB?

    - by jdowner
    Recently I wanted to create a bootable USB of Linux mint. I found that there was a lot of conflicting advice/experience about whether the 'dd' command could be used to create a bootable USB. I decided to download an ISO and try. While dd definitely put the image on the USB stick it was not bootable. So my question is what is the magic ingredient that will make this work or why has this approach persisted if it does not work? This is the command I used, dd if=/mint/iso/image of=/dev/sdb1 oflag=direct

  • Download and locally store all emails from all mailboxes on Office365?

    - by scape
    We have a business that uses Office365 and we want to be able to save all the emails locally. I found a thread on Office365 community pertaining to this and basically it was stated that there is no direct way of accomplishing this. I am curious if anyone has considered this and if there is a good method for storing these emails locally, even if it's some nifty PowerShell programming. All I've come up with is having a master mailbox which can view all mailboxes, and just have it sync and archive locally to the computer. I have not tried this yet, as the storage file sounds like it will be huge, so this does not seem like a fantastic idea and I'm open to any suggestions!

  • Pass a parameter from one jsp to another using form.action

    - by Ntz
    I have an ID that I need in the next jsp once the user click a button. I am trying to do the following: FirstJSP.jsp: function getSecond() { var frm = document.getElementById("frm"); frm.action = "**second.jsp?id=myId;"** frm.submit(); } ... form id="frm" ..... input type="button" value="Next" onclick="getSecond()"/ ...... This code takes me to my second page, but if I tried to access the id, it gives me an error since the id is null. I access the id in the second page by: final Long passedId = Long.parseLong(request.getParameter("id")); I think I am not passing the parameter correctly, but I don't know how to do it. Any ideas? Thank you so much!

  • Change web service url for a suds client on runtime (keeping the wsdl)

    - by patanpatan
    Hi. First of all, my question is similar to this one But it's a little bit different. What we have is a series of environments, with the same set of services. For some environments (the local ones) we can get access to the wsdl, and thus generating the suds client. For external environment, we cannot access the wsdl. But being the same, I was hoping I can change just the URL without regenerating the client. I've tried cloning the client, but it doesn't work.

  • Java Sql Udate error, data type missmatch

    - by codo
    I have created a table in ms access. I have set the data type of ID to Auto Number in MS-access. In java when I try to update a record. the netBeans IDE gives me the error of " data type missmatch in criteria expression". But when I changed the ID number that was not in the table already it works well. The code is below. String sql = "Update table1 set price ='" + txtPrice.getText() + "', quantity='" + txtQuantity.getText() + "', description='" + txtDescription.getText() + "' where id= " + txtid.getText() + ""; try { pst = conn.prepareStatement(sql); pst.executeUpdate(); JOptionPane.showMessageDialog(null, "Updated"); UpdateJTable(); } catch (Exception e) { JOptionPane.showMessageDialog(null, e); }

  • Separating data from the UI code with Linq to SQL entities

    - by Sir Psycho
    If it's important to keep data access 'away' from business and presentation layers, what alternatives or approaches can I take so that my LINQ to SQL entities can stay in the data access layer? So far I seem to be simply duplicating the classes produced by sqlmetal, and passing those object around instead simply to keep the two layers appart. For example, I have a table in my DB called Books. If a user is creating a new book via the UI, the Book class generated by sqlmetal seems like a perfect fit although I'm tightly coupling my design by doing so.

  • Is it possible to have a .NET route that maps to the same place as a directory?

    - by Austin
    I'm building a CMS using WebForms on .NET 4.0 and have the following route that allows URLs like www.mysite.com/about to be mapped to the Page.aspx page, which looks up the dynamic content. routes.MapPageRoute("page", "{name}", "~/Page.aspx"); The problem is that I have a couple of folders in my project that are interfering with possible URLs. For example, I have a folder called "blog" where I store pages related to handling blog functionality, but if someone creates a page for their site called "blog" then navigating to www.mysite.com/blog gets the following error: 403 - Forbidden: Access is denied. You do not have permission to view this directory or page using the credentials that you supplied. Other similar URLs route correctly, but I think because .NET is identifying /blog as a physical location on the server it is denying directory access. Is there a way to tell IIS / .NET to only look for physical files instead of files and folders?

  • Reference variable to an object instantiated/initialized in another class in Java

    - by Alex
    The reason I'm asking is because I'm getting NullPointerException. I now this is very easy but I'm pretty new programming and find this a bit confusing. So say I have initialized an object in a class and want to access that same object from another class. Like now for instance I'm working on a small Chess game, in my model Game class I have an instance of Board, an object. Board, in turn, has an array of Squares. Square[][]. Game has board, board has Square[][]. Now if I want to access the Square[][] through the object board (in Game) of type Board. Do I just declare a variable with the same name and type or do I have to initialize it again? Board board OR Board board = new Board(); Note, I have already initialized board in the class Game so if I do it again, won't they be two totally different Board objects?
