  • How to avoid session sharing provided by IE8 programatically in java/j2ee application ?

    - by Idiot
    Microsoft, in an effort to make Internet Explorer 8 "more stable" and “faster”, have changed the underlying architecture of the browser and introduced a function called "Loosely-Coupled IE" (LCIE) which works on session sharing across TAB and new instances. But session sharing may be fatal when some one is trying to do two different things at a time with the same application, e.g. like someone want to book one forward journey ticket and one return ticket at a time, at that time he will book 2 same tickets what he has not intended to. PROBABLE SOLUTION ON IT While creating new window Instead of creating by clicking on icon or Ctrl+N we should use File - New Session it will not happen. You can make a registry change on the client PC - adding the following. [HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Main] “TabProcGrowth" = dword : 00000000 Will disable "Loosely Couple IE8"; IE8 then works as previous versions of IE. But how i will do it programatically ?

  • Android: trouble updating to Android SDK Tools, revision 7.

    - by Arhimed
    Currently I have Android SDK 2.1 (+ tools revision 4). I'd like to upgrade to Android SDK 2.2. When I try to do it I'm informed I need to upgrade Android SDK Tools to revision 7 first. So I agree, the process starts and then I get an error: -= warning! =- A folder failed to be renamed or moved. On Windows this typically means that a program Is using that Folder (for example Windows Explorer or your anti-virus software.) Please momentarily deactivate your anti-virus software. Please also close any running programs that may be accessing the directory 'D:\Install\Programming\android-sdk-working-dir\android-sdk_r04-windows\android-sdk-windows\too!s'. When ready, press YES to try again. Downloading Android SDK Tools, revision 7 Installing Android SDK Tools, revision 7 Failed to rename directory D:\Install\Programming\android-sdk-working-dir\android-sdk_r04-windows\android-sdk-windows\tools to D:\Install\Programming\android-sdk-working-dir\android-sdk_r04-windows\android-sdk-windows\temp\ToolPackage.old01. I am aware of http/https and antivirus issues. So I disactivated my AV. I also closed any application that might hold a handle to the folder. Eclipse is also closed (I start the manager via command line). However I still get the same error. Looks like the only app that can hold a handle to the folder is the manager itself, because its starting directory is the one the error complains about ('\tools'). I am on Win XP Pro + SP3. Does anyone have an idea?

  • Is there a way to avoid putting the Perl version number into the "use lib" line for Perl modules in

    - by Kinopiko
    I am trying to install some Perl modules into a non-standard location, let's call it /non/standard/location. In the script which uses the module, it seems to be necessary to specify a long directory path including the version of Perl, like so: #!/usr/local/bin/perl use lib '/non/standard/location/lib/perl5/site_perl/5.8.9/'; use A::B; Is there any use lib or other statement which I can use which is not so long and verbose, and which does not include the actual version of Perl, in order that I don't have to go back and edit this out of the program if the version of Perl is upgraded?

  • How to avoid visual artifacts when hosting WPF user controls within a WinForms MDI app?

    - by jpierson
    When hosting WPF user controls within a WinForms MDI app there is a drawing issue when you have multiple forms that overlap each other that causes very distinct visual artifacts. These artifacts are mostly visible after dragging one child form over another one that also hosts WPF content or by allowing the edges of the child form to be clipped by the main MDI parent when dragging it around. After the drag and drop of the child form is completed the artifacts stay around gernally but I've found that setting focus to a different application's window and then refocusing back on to my application window that it is redrawn and all is good again until the child forms are moved once again. Please see the image below which demonstrates the problem. Since many at Microsoft insist that the WinForms MDI is already a complete solution for MDI even when dealing with WPF I find it hard to believe any of them have ever actually tried creating a mostly WPF app that utilizes WinForms MDI otherwise it would be hard to recommend while keeping a straignt face. I'm hoping to either come up with proof that this solution truly is not acceptable or possibly find a way to overcome this and a few other specific issues.

  • Extend linq-to-sql partial class to avoid writing a property?

    - by Curtis White
    I have a linq-to-sql class. I have a property "Password" for which I want to call the underlying ASP.NET Membership provider. Thus, I do not want this property written out directly but via my own code. I basically want to create a facade/proxy for this property such that I may use the underlying membership provider or a custom stored procedure. I want to accomplish without modifying the LINQ-TO-SQL designer generated code, if at all possible.

  • I'm referencing an WiX extension in a WiX library project -- how do I avoid having to reference this

    - by arathorn
    I'm referencing a WiX extension in a WiX library project. This WiX library project is itself referenced by my main WiX MSI project. Why does the main project have to also reference the WiX extension, even though it doesn't directly need it? I'd like to keep my wixlib's as self-contained as possible, so that other projects that use them don't need to know about their inner workings. I'm using latest stable release of WiX (3.0.x).

  • How do I avoid a repetitive subquery JOIN in SQL?

    - by Karl
    Hi In SQL Server 2008: I have one table, and I want to do something along the following lines: SELECT T1.stuff, T2.morestuff from ( SELECT code, date1, date2 from Table ) as T1 INNER JOIN ( SELECT code, date1, date2 from Table ) as T2 ON T1.code = T2.code and T1.date1 = T2.date2 The two subqueries are exactly identical. Is there any way I can do this without repeating the subquery script? Thanks Karl

  • In Python epoll can I avoid the errno.EWOULDBLOCK, errno.EAGAIN ?

    - by davyzhang
    I wrote a epoll wrapper in python, It works fine but recently I found the performance is not not ideal for large package sending. I look down into the code and found there's actually a LOT of error Traceback (most recent call last): File "/Users/dawn/Documents/workspace/work/dev/server/sandbox/single_point/tcp_epoll.py", line 231, in send_now num_bytes = self.sock.send(self.response) error: [Errno 35] Resource temporarily unavailable and previously silent it as the document said, so my sending function was done this way: def send_now(self): '''send message at once''' st = time.time() times = 0 while self.response != '': try: num_bytes = self.sock.send(self.response) l.info('msg wrote %s %d : %r size %r',self.ip,self.port,self.response[:num_bytes],num_bytes) self.response = self.response[num_bytes:] except socket.error,e: if e[0] in (errno.EWOULDBLOCK,errno.EAGAIN): #here I printed it, but I silent it in normal days #print 'would block, again %r',tb.format_exc() break else: l.warning('%r %r socket error %r',self.ip,self.port,tb.format_exc()) #must break or cause dead loop break except: #other exceptions l.warning('%r %r msg write error %r',self.ip,self.port,tb.format_exc()) break times += 1 et = time.time() I googled it, and says it caused by temporarily network buffer run out So how can I manually and efficiently detect this error instead it goes to exception phase? Because it cause to much time to rasie/handle the exception.

  • AJAX: how to get progress feedback in web apps, and to avoid timeouts on long requests?

    - by David Dombrowsky
    This is a general design question about how to make a web application that will receive a large amount of uploaded data, process it, and return a result, all without the dreaded spinning beach-ball for 5 minutes or a possible HTTP timeout. Here's the requirements: make a web form where you can upload a CSV file containing a list of URLs when the user clicks "submit", the server fetches the file, and checks each URL to see if its alive, and what the title tag of the page is. the result is a downloadable CSV file containing the URL, and the result HTTP code the input CSV can be very large ( 100000 rows), so the fetch process might take 5-30 minutes. My solution so far is to have a spinning javascript loop on the client site, which queries the server every second to determine the overall progress of the job. This seems kludgy to me, and I'm hesitant to accept this as the best solution. I'm using perl, template toolkit, and jquery, but any solution using any web technology would be acceptable.

  • How to avoid OLEDB converting "."s into "#"s in column names?

    - by Andrew Miner
    I'm using the ACE OLEDB driver to read from an Excel 2007 spreadsheet, and I'm finding that any '.' character in column names get converted to a '#' character. For example, if I have the following in a spreadsheet: Name Amt. Due Due Date Andrew 12.50 4/1/2010 Brian 20.00 4/12/2010 Charlie 1000.00 6/30/2010 the name of the second column would be reported as "Amt# Due" when read with the following code: OleDbConnection connection = new OleDbConnection( "Provider=Microsoft.ACE.OLEDB.12.0; Data Source={0}; " + "Extended Properties=\"Excel 12.0 Xml;HDR=YES;FMT=Delimited;IMEX=1\""); OldDbCommand command = new OleDbCommand("SELECT * FROM MyTable", connection); OleDbReader dataReader = command.ExecuteReader(); System.Console.WriteLine(dataReader.GetName(1)); I've read through all the documentation I can find and I haven't found anything which even mentions that this will happen. Has anyone run into this before? Is there a way to fix this behavior?

  • In what case does IE8 block Javascript and how to avoid it ?

    - by e-satis
    I got a web site using jQuery, jQuery Tools and some handcrafted JS running performing graphical enhancements. While it's running smooth on FF, Safari and Chrome, IE blocks the script execution : There is nothing particularly more dangerous on this code than, let's say, on Netvibes. Why is even talking about activeX ? I'm using JS. And how can I prevent that ? I don't want my user to click on "I allow this website" to work. It would be like putting a big red absolute DIV reading "Live quick and never come back".

  • How to avoid using duplicate savepoint names in nested transactions in nested stored procs?

    - by Gary McGill
    I have a pattern that I almost always follow, where if I need to wrap up an operation in a transaction, I do this: BEGIN TRANSACTION SAVE TRANSACTION TX -- Stuff IF @error <> 0 ROLLBACK TRANSACTION TX COMMIT TRANSACTION That's served me well enough in the past, but after years of using this pattern (and copy-pasting the above code), I've suddenly discovered a flaw which comes as a complete shock. Quite often, I'll have a stored procedure calling other stored procedures, all of which use this same pattern. What I've discovered (to my cost) is that because I'm using the same savepoint name everywhere, I can get into a situation where my outer transaction is partially committed - precisely the opposite of the atomicity that I'm trying to achieve. I've put together an example that exhibits the problem. This is a single batch (no nested stored procs), and so it looks a little odd in that you probably wouldn't use the same savepoint name twice in the same batch, but my real-world scenario would be too confusing to post. CREATE TABLE Test (test INTEGER NOT NULL) BEGIN TRAN SAVE TRAN TX BEGIN TRAN SAVE TRAN TX INSERT INTO Test(test) VALUES (1) COMMIT TRAN TX BEGIN TRAN SAVE TRAN TX INSERT INTO Test(test) VALUES (2) COMMIT TRAN TX DELETE FROM Test ROLLBACK TRAN TX COMMIT TRAN TX SELECT * FROM Test DROP TABLE Test When I execute this, it lists one record, with value "1". In other words, even though I rolled back my outer transaction, a record was added to the table. What's happening is that the ROLLBACK TRANSACTION TX at the outer level is rolling back as far as the last SAVE TRANSACTION TX at the inner level. Now that I write this all out, I can see the logic behind it: the server is looking back through the log file, treating it as a linear stream of transactions; it doesn't understand the nesting/hierarchy implied by either the nesting of the transactions (or, in my real-world scenario, by the calls to other stored procedures). So, clearly, I need to start using unique savepoint names instead of blindly using "TX" everywhere. But - and this is where I finally get to the point - is there a way to do this in a copy-pastable way so that I can still use the same code everywhere? Can I auto-generate the savepoint name on the fly somehow? Is there a convention or best-practice for doing this sort of thing? It's not exactly hard to come up with a unique name every time you start a transaction (could base it off the SP name, or somesuch), but I do worry that eventually there would be a conflict - and you wouldn't know about it because rather than causing an error it just silently destroys your data... :-(

  • How to avoid "The name 'ConfigurationManager' does not exist in the current context" error?

    - by 5YrsLaterDBA
    I am using VS2008. I have a project connect with a database and the connection string is read from App.config via ConfigurationManager. We are using L2E. Now I added a helper project, AndeDataViewer, to have a simple UI to display data from the database for testing/verification purpose. I don't want to create another set of Entity Data Model in the helper project. I just added all related files as a link in the new helper project. When I compile, I got the following error: Error 15 The name 'ConfigurationManager' does not exist in the current context C:\workspace\SystemSoftware\SystemSoftware\src\systeminfo\RuntimeInfo.cs 24 40 AndeDataViewer I think I may need to add another project setting/config related file's link to the helper project from the main project? There is no App.config file in the new helper project. But it looks I cannot add that file's link to the helper project. Any ideas?

  • Having a little trouble with this Java code. Beginner probably mixing some things with C#.

My question is, in Java do methods have to have static in order to use them even if they are in the same class?

  • For a primary key of an integral type, why is it important to avoid gaps ?

    - by Jacques René Mesrine
    I am generating a surrogate key for a table & due to my hi/lo algorithm, everytime you reboot/restart the machine, gaps may appear. T1: current hi = 10000000 (sequence being dished out .. 1 to 100) Assume that current sequence is 10000050 T2: restart system. T3: System gives out the next_hi as 10000100 (sequence being dished out now ranges from 101 to 200) T4: Next request for a key returns 100001001 From a primary key or indexing internals perspective, why is it important that there be no gaps in the sequences ? I'm asking this for a deeper understanding of mysql specifically. Thanks

  • Trouble with onscreen keyboard orientation in iPhone OpenGL ES application.

    - by Plumenator
    I need to take keyboard input in my OpenGL ES application, so I just created an empty UITextView and added it as a subview to the main window along with the view that presents my content. I use the UITextview to control the keyboard and it works fine in a single orientation. I then changed my code to support all orientations by rotating the OpenGL content myself based on UIDeviceOrientation notifications. To rotate the keyboard, I overrode the shouldAutoRotateInterfaceOrientation method in the UITextView's controller. But I still see that the keyboard does not rotate according to the orientation. Any clues?

    - by Patrick
    Im trying to use CURL to scrape the results from the page http://adlab.msn.com/Online-Commercial-Intention/Default.aspx My understanding, is that i visit this page, it places cookie info and sets a few variables.

  • How to avoid the "divide by zero" error in SQL?

    - by Henrik Staun Poulsen
    I hate this error message: Msg 8134, Level 16, State 1, Line 1 Divide by zero error encountered. What is the best way to write SQL code, so that I will never see this error message again? I mean, I could add a where clause so that my divisor is never zero. Or I could add a case statement, so that there is a special treatment for zero. Is the best way to use a NullIf clause? Is there better way, or how can this be enforced?
