  • Javascript to take a screenshot of a website without using ActiveX

    - by Jourkey
    I have a JS app that an user interacts with. I need to save the appearance of the interface at the current time, crop out the part that I need (or only shot the part that I need by specifying the div), and send it back to the server. Clearly any external services would not be able to do this, I need a javascript (or flash) script that can save the screen appearance. Is this possible? Thanks. Also, as the comment below says, I cannot use Active X.

  • GUI and Threading

    - by cam
    Isn't there a better way to handle GUI (WinForms) from another thread than creating a delegate for every single method I need to use? It seems like there would be a better way. Here's the current code I use for every single GUI method: private delegate void SetStatusTextDelegate(string set_text); public void SetStatusText(string set_text) { if (status_prog.InvokeRequired) { status_prog.Invoke(new SetStatusTextDelegate(SetStatusText), set_text); } else { status_prog.Text = set_text; } }

  • User Defined Exceptions with JMX

    - by Daniel
    I have exposed methods for remote management in my application server using JMX by creating an MXBean interface, and a class to implement it. Included in this interface are operations for setting attributes on my server, and for getting the current value of attributes. For example, take the following methods: public interface WordManagerMXBean { public void addWord(String word); public WordsObject getWords(); public void removeWord(String word); } The WordsObject is a custom, serializable class used to retrieve data about the state of the server. Then I also have a WordManager class that implements the above interface. I then create a JMX agent to manage my resource: MBeanServer mbs = ManagementFactory.getPlatformMBeanServer(); ObjectName wordManagerName = new ObjectName("com.example:type=WordManager"); mbs.registerMBean(wordManager, wordManagerName); I have created a client that invokes these methods, and this works as expected. However, I would like to extend this current configuration by adding user defined exceptions that can be sent back to my client. So I would like to change my interface to something like this: public interface WordManagerMXBean { public void addWord(String word) throws WordAlreadyExistsException; public WordsObject getWords(); public void removeWord(String word); } My WordAlreadyExistsException looks like this: public class WordAlreadyExistsException extends Exception implements Serializable { private static final long serialVersionUID = -9095552123119275304L; public WordAlreadyExistsException() { super(); } } When I call the addWord() method in my client, I would like to get back a WordAlreadyExistsException if the word already exists. However, when I do this, I get an error like this: java.rmi.UnmarshalException: Error unmarshaling return; nested exception is: java.lang.ClassNotFoundException: com.example.WordAlreadyExistsException The WordAlreadyExistsException, the WordsObject and the WordManagerMXBean interface are all in a single jar file that is available to both the client and the server. If I call the getWords() method, the client has no difficulty handling the WordsObject. However, if a user defined exception, like the one above, is thrown, then the client gives the error shown above. Is it possible to configure JMX to handle this exception correctly in the client? Following some searching, I noticed that there is an MBeanException class that is used to wrap exceptions. I'm not sure if this wrapping is performed by the agent automatically, or if I'm supposed to do the wrapping myself. I tried both, but in either case I get the same error on the client. I have also tried this with both checked and unchecked exceptions, again the same error occurs. One solution to this is to simply pass back the error string inside a generic error, as all of the standard java exceptions work. But I'd prefer to get back the actual exception for processing by the client. Is it possible to handle user defined exceptions in JMX? If so, any ideas how?

  • how to remove empty tags in input xml

    - by SGB
    My java module gets a huge input xml from a mainframe. Unfortunately, the mainframe is unable to skip optional elements when it is not a leaf node, with the result that I get a LOT of empty tags in my input : So, <pre><code><SSN>111111111</SSN> <Employment> <Current> <Address> <line1/> <line2/> <line3/> <city/> <state/> <country/> </Address> <Phone> <phonenumber/> <countryCode/> </Phone> </Current> <Previous> <Address> <line1/> <line2/> <line3/> <city/> <state/> <country/> </Address> <Phone> <phonenumber/> <countryCode/> </Phone> </Previous> </Employment> <MaritalStatus>Single</MaritalStatus> </code></pre> should be <SSN>111111111</SSN> <MaritalStatus>Single</MaritalStatus> I use jaxb to unmarshall the input xml string that the mainframe sends it. Is there a clean/ easy way to remove all the empty group tags, or do I have to do this manuall in the code for each element. I have over 35 elements in my input xml, so I would love to it if jaxb itself had a way of doing this automatically? Thanks, SGB

  • If we don't like it for the presentation layer, then why do we tolerate it for the behavior layer?

    - by greim
    Suppose CSS as we know it had never been invented, and the closest we could get was to do this: <script> // this is the page's stylesheet $(document).ready(function(){ $('.error').css({'color':'red'}); $('a[href]').css({'textDecoration':'none'}); ... }); </script> If this was how we were forced to write code, would we put up with it? Or would every developer on Earth scream at browser vendors until they standardized upon CSS, or at least some kind of declarative style language? Maybe CSS isn't perfect, but hopefully it's obvious how it's better than the find things, do stuff method shown above. So my question is this. We've seen and tasted of the glory of declarative binding with CSS, so why, when it comes to the behavioral/interactive layer, does the entire JavaScript community seem complacent about continuing to use the kludgy procedural method described above? Why for example is this considered by many to be the best possible way to do things: <script> $(document).ready(function(){ $('.widget').append("<a class='button' href='#'>...</div>"); $('a[href]').click(function(){...}); ... }); </script> Why isn't there a massive push to get XBL2.0 or .htc files or some kind of declarative behavior syntax implemented in a standard way across browsers? Is this recognized as a need by other web development professionals? Is there anything on the horizon for HTML5? (Caveats, disclaimers, etc: I realize that it's not a perfect world and that we're playing the hand we've been dealt. My point isn't to criticize the current way of doing things so much as to criticize the complacency that exists about the current way of doing things. Secondly, event delegation, especially at the root level, is a step closer to having a declarative behavior layer. It solves a subset of the problem, but it can't create UI elements, so the overall problem remains.)

  • authentication winform + asp

    - by user156144
    I am building a desktop application that needs to update current user's status frequently. This status will be available as RSS feed. In order to do this, I think I can create a asp.net folder and secure it using form authentication. When the desktop application written as winform in c# needs to update status, it can set WebRequest.Credentials and upload data. Is there any better way of doing this? Thanks

  • django redirect url containing id

    - by dana
    hello, i want to add in my settings.py a declaration like: LOGIN_REDIRECT_URL='^private_profile/(?P<id>\d+)/$' #or LOGIN_REDIRECT_URL='/accounts/private_profile/id/' so that when the user with the id 1, for example,is logging in, he will be redirected to LOGIN_REDIRECT_URL='/accounts/private_profile/1/' but both alternatives, LOGIN_REDIRECT_URL='^private_profile/(?P<id>\d+)/$' #or LOGIN_REDIRECT_URL='/accounts/private_profile/id/' are wrong, because in my browser i don't see the current user id, where am i wrong? Thanks

  • C# - Extract Zip with file listing

    - by fonix232
    I would like to extract a pre-set zip file WITHOUT an external library to a given folder, and I would like to inform the user about the current percent of extraction (with a simple progressBar and a percent label) and the currently extracted file. Is this possible somehow? It is important to do not use any other library. (For updating all the labels and progressBar, I use a separate backgroundWorker)
