  • How can I reuse my javascript code between client and server?

    - by Chris Farmer
    I have some javascript code that includes an ANTLR-generated lexer and parser, and some associated syntax tree evaluation functionality. This code runs in the browser in my web app to support users who author code snippets which process scientific data. Now I'd like to do some additional background processing on the server using the same generated parser. I would prefer not to have to re-implement this stuff in C# and have multiple bits of code that did the exact same thing. Performance isn't as critical to me as eliminating duplication, since this is a background process. So, how can I call into my javascript code from C#? And how can I format my script so that it plays nicely with my .NET web app?

  • Windows Azure worker roles: One big job or many small jobs?

    - by Ryan Elkins
    Is there any inherent advantage when using multiple workers to process pieces of procedural code versus processing the entire load? In other words, if my workflow looks like this: Get work from queue0 and do A Store result from A in queue1 Get result from queue 1 and do B Store result from B in queue2 Get result from queue2 and do C Is there an inherent advantage to using 3 workers who each do the entire process themselves versus 3 workers that each do a part of the work (Worker 1 does 1 & 2, worker 2 does 3 & 4, worker 3 does 5). If we only care about working being done (finished with step 5) it would seem that it scales the same way (once you're using at least 3 workers). Maybe the big job is better because workers with that setup have less bottleneck issues?

  • IPhone Dev: Activate the view of a tabBar button

    - by Alex N Sanchez
    Hi, I have an application that has a tabBar that handles all the views. In the first view I have a login process. When that process finishes I want to go automatically to the second tabBar view without making the user to click in its respective tabBar button. All I've got until now is to highlight the button with this: myTabBar.selectedItem = [myTabBar.items objectAtIndex:1]; But I have no idea about how to bring the second view related to that button to the front, automatically. Until now the user has to press the button when it gets lighted (selected). Any idea about how to do this? Is it possible? It would be much appreciated. Thanks.

  • BizTalk and SQL: Alternatives to the SQL receive adapter. Using Msmq to receive SQL data

    - by Leonid Ganeline
    If we have to get data from the SQL database, the standard way is to use a receive port with SQL adapter. SQL receive adapter is a solicit-response adapter. It periodically polls the SQL database with queries. That’s only way it can work. Sometimes it is undesirable. With new WCF-SQL adapter we can use the lightweight approach but still with the same principle, the WCF-SQL adapter periodically solicits the database with queries to check for the new records. Imagine the situation when the new records can appear in very broad time limits, some - in a second interval, others - in the several minutes interval. Our requirement is to process the new records ASAP. That means the polling interval should be near the shortest interval between the new records, a second interval. As a result the most of the poll queries would return nothing and would load the database without good reason. If the database is working under heavy payload, it is very undesirable. Do we have other choices? Sure. We can change the polling to the “eventing”. The good news is the SQL server could issue the event in case of new records with triggers. Got a new record –the trigger event is fired. No new records – no the trigger events – no excessive load to the database. The bad news is the SQL Server doesn’t have intrinsic methods to send the event data outside. For example, we would rather use the adapters that do listen for the data and do not solicit. There are several such adapters-listeners as File, Ftp, SOAP, WCF, and Msmq. But the SQL Server doesn’t have methods to create and save files, to consume the Web-services, to create and send messages in the queue, does it? Can we use the File, FTP, Msmq, WCF adapters to get data from SQL code? Yes, we can. The SQL Server 2005 and 2008 have the possibility to use .NET code inside SQL code. See the SQL Integration. How it works for the Msmq, for example: ·         New record is created, trigger is fired ·         Trigger calls the CLR stored procedure and passes the message parameters to it ·         The CLR stored procedure creates message and sends it to the outgoing queue in the SQL Server computer. ·         Msmq service transfers message to the queue in the BizTalk Server computer. ·         WCF-NetMsmq adapter receives the message from this queue. For the File adapter the idea is the same, the CLR stored procedure creates and stores the file with message, and then the File adapter picks up this file. Using WCF-NetMsmq adapter to get data from SQL I am describing the full set of the deployment and development steps for the case with the WCF-NetMsmq adapter. Development: 1.       Create the .NET code: project, class and method to create and send the message to the MSMQ queue. 2.       Create the SQL code in triggers to call the .NET code. Installation and Deployment: 1.       SQL Server: a.       Register the CLR assembly with .NET (CLR) code b.      Install the MSMQ Services 2.       BizTalk Server: a.       Install the MSMQ Services b.      Create the MSMQ queue c.       Create the WCF-NetMsmq receive port. The detailed description is below. Code .NET code … using System.Xml; using System.Xml.Linq; using System.Xml.Serialization;   //namespace MyCompany.MySolution.MyProject – doesn’t work.

Creating the WCF-NetMsmq receive port I will not go through this step in all details. It is straightforward. URI for this receive location should be 'net.msmq://localhost/private/myapp.myqueue'. Notes ·         The biggest problem is usually on the step the “Registering the CLR assembly”. It is hard to predict where are the assemblies from the assembly list, what version should be used, x86 or x64. It is pity of such “rude” integration of the SQL with .NET. ·         In couple cases the new WCF-NetMsmq port was not able to work with the queue. Try to replace the WCF- NetMsmq port with the WCF-Custom port with netMsmqBinding. It was working fine for me. ·         To test how messages go through the queue you can turn on the Journal /Enabled option for the queue. I used the QueueExplorer utility to look to the messages in Journal. The Computer Management can also show the messages but it shows only small part of the message body and in the weird format. The QueueExplorer can do the better job; it shows the whole body and Xml messages are in good color format.

  • Asp.Net MVC2 TekPub Starter Site methodology question

    - by Pino
    Ok I've just ran into this and I was only supposed to be checking my emails however I've ended up watching this (and not far off subscribing to TekPub). http://tekpub.com/production/starter Now these app is a great starting point, but it raises one issue for me and the development process I've been shown to follow (rightly or wrongly). There is no conversion from the LinqToSql object when passing data to the view. Are there any negitives to this? The main one I can see is with validation, does this cause issues when using MVC's built in validation as this is somthing we use extensivly. Because we are using the built in objects generated by LinqToSql how would one go about adding validation, like [Required(ErrorMessage="Name is Required")] public string Name {get;set;} Interested to understand the benifits of this methodology and any negitives that, should we take it on, experiance through the development process.

  • ModalPopupExtender OnShow Event

    - by Thomas
    When clicking a button, I have a ModalPopupExtender (Panel) that gets displayed. I can't seem to trigger any event during that process. Adding an event to the button that opens the ModalPopupExtender doesnt work, as it never triggers. Adding the button as a trigger in my UpdatePanel also doesnt work. Scenario: I have a gridview with a button outside of the gridview. Clicking the button opens up a ModalPopupExtender which needs to display the checkboxes clicked on the gridview. I have the code to get the checkboxes clicked on the Gridview, however I cant seem to use an event during the process of opening the ModalPopupExtender.

  • jQuery Form Processing With PHP to MYSQL Database Using $.ajax Request

    - by FrustratedUser
    Question: How can I process a form using jQuery and the $.ajax request so that the data is passed to a script which writes it to a database? Problem: I have a simple email signup form that when processed, adds the email along with the current date to a table in a MySQL database. Processing the form without jQuery works as intended, adding the email and date. With jQuery, the form submits successfully and returns the success message. However, no data is added to the database. Any insight would be greatly appreciated! <!-- PROCESS.PHP --> <?php // DB info $dbhost = '#'; $dbuser = '#'; $dbpass = '#'; $dbname = '#'; // Open connection to db $conn = mysql_connect($dbhost, $dbuser, $dbpass) or die ('Error connecting to mysql'); mysql_select_db($dbname); // Form variables $email = $_POST['email']; $submitted = $_POST['submitted']; // Clean up function cleanData($str) { $str = trim($str); $str = strip_tags($str); $str = strtolower($str); return $str; } $email = cleanData($email); $error = ""; if(isset($submitted)) { if($email == '') { $error .= '<p class="error">Please enter your email address.</p>' .

  • Background job with status in rails

    - by pepernik
    Hey. I would like to upload a file and then parse it. Because parsing can take up to 10min I installed delayed_job plugin and called parsing function through send_later function. I have to mention that this is an AJAX app. Imagine that you press an AJAX button that starts upload and after that the source is imported into the database. During the process I want to show the progress bar or message (importing...) and when it completes the task status changes to done. My question is: What is the best way to check for status of the process. What would you do? My idea is to have another controller actions "status" which look into the database and provide the right status.

  • PHP form validation question?

    - by GeNx
    I have a form that validates the email address and I want to be able to place echo '<p class="error">Please enter a valid email address!</p>'; anywhere on the web page without having to put the validation process within the html? Or should I include the validation process in the HTML form? Here is the php code. if (preg_match ('/^[\w.-]+@[\w.-]+\.[A-Za-z]{2,6}$/', $_POST['email'])) { $email = mysqli_real_escape_string($mysqli, strip_tags($_POST['email'])); } else { echo '<p class="error">Please enter a valid email address!</p>'; }

  • GetDC() DllImport for x64 apps

    - by devdept
    If you make a little research on the internet you'll see many DLLImport styles for this user32.dll function: HDC GetDC(HWND hWnd); The question is: what type is more appropriate for .NET x64 apps (either compiled with the Platform target as AnyCPU on a x64 machine or specifically as x64)? IntPtr for example grows to a size of 8 on a x64 process, can this be a problem? Is uint more appropriate than Uint64? What is the size of the pointers this function uses when used in a x64 process? The DLL is called user32.dll does it work as 32bit or 64bit on a x64 operating system? [DllImport("user32.dll",EntryPoint="GetDC")] public static extern IntPtr GetDC(IntPtr hWnd); public static extern uint GetDC(uint hWnd); public static extern int GetDC(int hWnd); Thanks!

  • OS memory allocation addresses

    - by user1777914
    Quick curious question, memory allocation addresses are choosed by the language compiler or is it the OS which chooses the addresses for the memory asked? This is from a doubt about virtual memory, where it could be quickly explained as "let the process think he owns all the memory", but what happens on 64 bits architectures where only 48 bits are used for memory addresses if the process wants a higher address? Lets say you do a int a = malloc(sizeof(int)); and you have no memory left from the previous system call so you need to ask the OS for more memory, is the compiler the one who determines the memory address to allocate this variable, or does it just ask the OS for memory and it allocates it on the address returned by it?

  • msvcrt: memory usage goes wild, but not under debugger

    - by al_miro
    I have a C++ code compiled with Intel compiler, 32bit, in MS VC6 mode, so using either msvcrt.dll or msvcrtd.dll. The process makes heavy memory allocation and deallocation. I monitor the memory usage with WMI and look at VirtualSize and WorkingSetSize. with debug runtime (msvcrtd.dll): virtual constant 1.7GB, working constant 1.2GB with non-debug runtime (msvcrt.dll): virtual raising 1.7-- 2.1GB, working raising 1.2-1.4GB with non-debug runtime but under debugger (windbg): virtual constant 1.7GB, working constant At 2.1 GB virtual the process is crashing (as expected). But why would the virtual usage increase only with (non-debug) msvcrt.dll and only if not under debugger? In all cases compilation flags are identical, only runtime libs are different.

  • Make MySQL database replication always use the most free node?

    - by Chad Johnson
    We started using Multi-Master Replication Manager for MySQL, and I am wondering whether it is possible to to treat this setup like multi-symmetric processing: a process pops off the process queue, and the node (in this case a server) that is most free is selected for the job. It seems that what happens is, the service switches to a slave ONLY when it mysqld crashes or goes away. Is there a way to make database replication for MySQL act in more of a distributed manner? Maybe there is other software besides MMM that can do this? Is there a way to switch the reader role to another server whene mysqld slows down (rather than just when it fails)?

  • Avoiding exceptions when uploading files in laravel

    - by occam98
    I've got a file upload field (attachment1) in a form that may or may not have a file uploaded in it when I process the form in laravel. When I'm trying to process the page, this line generates an exception: Input::upload('attachment1',path('storage').'attachments/'.$name); Here is the text of the exception: Message: Call to a member function move() on a non-object it seems that I need to check in advance to see if 'attachment1' has a file, and I found that the function Input::has_file('attachment1') is supposed to tell me whether or not 'attachment1' has a file, but even when I submit an empty form, it returns true. Also, from reading documentation, it seems that Input::upload is supposed to just return false when trying to upload a non-existant file, so why does it produce this exception instead, and how can I fix it?

  • Lose changed data in session

    - by user150528
    Our asp.net 2.0 application has a very long process (synchronized) before sending response back to client. I observed that a second request, exactly same the initial one, was sent after client IE8 waited response for a long period of time while our application was still processing the first request. I use page session with predefined key to store a flag when the initial request arrives and then starts long process while client IE waits for the response, so if second request comes in, our application checks the session value. After our application sets the session flag and starts processing, I use Fiddler “Abort Session” to abort the initial request, right away the second request (same as the first one) is sent automatically, but session value set earlier seems no longer exist. Any thoughts?

    I've downloaded a patch from some site and trying to apply it (twisted, python web framework). Several hunks failed. How do I automate manual patching process using vim? Details: I'm trying to automate the process of applying failed hunks. Many tiny changes, each about adding/removing 1-2 chars. Difficult to see. I Have to create two new temporary files and :diffthis them manually to see the difference. Yes, outside VCS. I can imagine a neat way to deal with it using git, but I would prefer to avoid creating git repo for that.

  • Does anyone know a better alternative to MS Excel's Solver?

    - by tundal45
    My company has to crunch a lot of data and part of the process involves running the solver and plotting a graph through resulting data points. Obviously there is a lot of copy and paste involved and the whole process is shaky, error prone and all round cluster-fudge. I was wondering if there was an alternative to the solver that can be used so that even if we have to use excel to plot the final graph, there will be a lot less data that needs to be copied and pasted back and forth. It would be great especially if the tool could be easily integrated into a .NET application but I am open to suggestions that may require a little bit of code-fu to get this to work. Thanks!

  • glibc backtrace - can't redirect output to file

    - by Jason Antman
    Hi, I'm in the process of debugging a C program (that I didn't write). I have all of the internal debugging tools (a whole bunch of printf's) enabled, and I wrote a small PHP script that uses proc_open() and just grabs both stdout and stderr, and time-coordinates them in one file. At the moment, the binary is dieing with a realloc() error that's caught by glibc, and a glibc backtrace is printed, beginning with: *** glibc detected *** /sbin/rsyslogd: realloc(): invalid next size: 0x00002ace626ac910 *** Here's the thing I don't understand: I've confirmed that the PHP script is catching both stdout and stderr from the binary's process and writing them to the correct files, but this backtrace is still printed to the console. Where is this coming from? Is there some magical output channel other than stdout and stderr? Any ideas on how I go about capturing this backtrace to a file, or sending it out with stderr? Thanks, Jason

    I'm having trouble using Process.Start with Firefox. I want to start a new instance of Firefox in a minimized window. The following works fine with Internet Explorer, notepad, etc.: ProcessStartInfo p = new ProcessStartInfo(); p.FileName = "iexplore.exe"; p.Arguments = "http://www.google.com"; p.WindowStyle = ProcessWindowStyle.Minimized; Process.Start(p); This opens IE in a new, minimized window. Good, just what I want. If I try the exact same thing but instead supply Firefox in the p.FileName, it opens Firefox in a "normal" window, rather than minimized. I've tried various changes to arguments, also have tried examining my local Firefox settings (under Tools/Options) with no luck. I'm sure I'm just missing something simple, but can't figure out what it is. If anyone can help me with getting Firefox opened in a minimized state it would be greatly appreciated!

  • Automate paster create -t plone3_buildout

    - by roopesh
    I want to automate the process of plone3_buildout. Explanation: The default(the one I use) way of building a plone site is using paster, like so: paster create -t plone3_buildout This asks me a few questions and then create a default buildout for the site. What I want: I want to automate this process using buildout. My buildout will execute this paster command, feed in my preconfigured values to the paster. I haven't found a recipe which can do this. If someone has an idea of how to do this, please share the info. If there is a recipe which can feed values to interactive commands(with known output, like with plone3_buildout command), that would be useful too.
