  • asp.net mvc Ajax.BeginForm clone.

    - by denis_n
    Hello, I'm using asp.net mvc ajax. The partial view is using Ajax.BeginForm (just an example): <div id="divPlaceholder"> <% using (Ajax.BeginForm(new AjaxOptions { UpdateTargetId = "divPlaceholder" })) { %> ... asp.net mvc controls and validation messages <input type="submit" value="Save" /> <% } %> </div> After update, if validation fails, the html is: <div id="divPlaceholder"> <div id="divPlaceholder"> ...form </div> </div> I don't like that the returned html is inserted, instead it should replace original div. Probably on POST I should not render <div> around form in partial view or render the div without id. What else can I do in this situation? I was thinking that maybe I should write a helper, something like Ajax.DivBeginForm, which will render form inside div on GET and hide the div on POST. Can somebody provide a good advice how to write such helper (Ajax.DivBeginForm)? I'd like it to work with using keyword: <% using (Ajax.DivBeginForm(new AjaxOptions { UpdateTargetId = "myId" })) { ... }%>

  • PHP/MySQL - Working with two databases, one shared and one local to an instance of application

    - by Extrakun
    The situation: Using a off-the-shelf PHP application, I have to add in a new module for extra functionality. Today, it is made known that eventually four different instances of the application are to be deployed, but the data from the new functionality is to be shared among those 4 instances. Each instance should still have their own database for users, content and etc. So the data for the new functionality goes into a 'shared' database. The data for the application (user login, content, uploads) go into a 'local' database To make things more complex, the new module I am writing will fetch data from the local DB and the shared DB at the same time. A re-write of the base application will take too long. I only have control over the new module which I am writing. The ideal solution: Is there a way to encapsulate 2 databases into one name using MySQL? I do not wish to switch DB connections or specifically name the DB to query from inside my SQL statements. The application uses a DB wrapper, so I am able to change it somehow so I can invisibly attempt to read/write to two different DB. What is the best way to handle this problem?

  • Writing datatable to database file, one record at a time in C#

    - by Kevin
    Hi! I want to write a C# program that will read a row from a datatable (named loadDT) and update a database file (named Forecasts.mdb). My datatable looks like this (each day's value is a number representing kilowatts usage forecast): Hour Day1 Day2 Day3 Day4 Day5 Day6 Day7 1 519 520 524 498 501 476 451 My database file looks like this: Day Hour KWForecast 1 1 519 2 1 520 3 1 524 ... and so on. Basically, I want to be able to read one row from the datatable, and then extrapolate that out to my database file, one record at a time. Each row from the datatable will result in seven records written to the database file. Any ideas on how to go about this? I can connect to my database, the connection string works, and I can update and delete from the database. I just can't wrap my head around how to do this one record at a time. Thanks in advance for any help and advice.

  • Python's asyncore to periodically send data using a variable timeout. Is there a better way?

    - by Nick Sonneveld
    I wanted to write a server that a client could connect to and receive periodic updates without having to poll. The problem I have experienced with asyncore is that if you do not return true when dispatcher.writable() is called, you have to wait until after the asyncore.loop has timed out (default is 30s). The two ways I have tried to work around this is 1) reduce timeout to a low value or 2) query connections for when they will next update and generate an adequate timeout value. However if you refer to 'Select Law' in 'man 2 select_tut', it states, "You should always try to use select() without a timeout." Is there a better way to do this? Twisted maybe? I wanted to try and avoid extra threads. I'll include the variable timeout example here: #!/usr/bin/python import time import socket import asyncore # in seconds UPDATE_PERIOD = 4.0 class Channel(asyncore.dispatcher): def __init__(self, sock, sck_map): asyncore.dispatcher.__init__(self, sock=sock, map=sck_map) self.last_update = 0.0 # should update immediately self.send_buf = '' self.recv_buf = '' def writable(self): return len(self.send_buf) > 0 def handle_write(self): nbytes = self.send(self.send_buf) self.send_buf = self.send_buf[nbytes:] def handle_read(self): print 'read' print 'recv:', self.recv(4096) def handle_close(self): print 'close' self.close() # added for variable timeout def update(self): if time.time() >= self.next_update(): self.send_buf += 'hello %f\n'%(time.time()) self.last_update = time.time() def next_update(self): return self.last_update + UPDATE_PERIOD class Server(asyncore.dispatcher): def __init__(self, port, sck_map): asyncore.dispatcher.__init__(self, map=sck_map) self.port = port self.sck_map = sck_map self.create_socket(socket.AF_INET, socket.SOCK_STREAM) self.bind( ("", port)) self.listen(16) print "listening on port", self.port def handle_accept(self): (conn, addr) = self.accept() Channel(sock=conn, sck_map=self.sck_map) # added for variable timeout def update(self): pass def next_update(self): return None sck_map = {} server = Server(9090, sck_map) while True: next_update = time.time() + 30.0 for c in sck_map.values(): c.update() # <-- fill write buffers n = c.next_update() #print 'n:',n if n is not None: next_update = min(next_update, n) _timeout = max(0.1, next_update - time.time()) asyncore.loop(timeout=_timeout, count=1, map=sck_map)

  • 50 sequences in one line

    - by user343934
    I have Muttiple sequence alignment (clustal) file and i want to read this file and arrange sequences in a such a way that in looks more clear and precise in order. I am doing this from biopython using AlignIO object. My codes like this alignment = AlignIO.read("opuntia.aln", "clustal") print "Number of rows: %i" % len(align) for record in alignment: print "%s - %s" % (record.id, record.seq) My Output-- http://i48.tinypic.com/ae48ew.jpg , it looks messy and long scrolling. What i want to do is print only 50 sequences in each line and continue till the end of alignment file. I wish to have output like this---http://i45.tinypic.com/4vh5rc.jpg from --http://www.ebi.ac.uk/Tools/clustalw2/, sorry two links are just a text due to my reputation. Any suggestions, algorithm and sample code is appreciated Thanks in advance Br,

  • Track mass email campaigns

    - by daeliur
    Litmus released an email analytics service last month (may 2010). See here: http://litmusapp.com/email-analytics They boast a very cool "read rate" tracking: they can track normal reads, Skims, and Glanced/Deleted. How can they track skims and glanced/deleted? This to me seems impossible :) They also track forwards and prints. Prints are easy (they include a css @media print query with a bg image). But forwards? I think this might be a combo between subsequent opens and different IPs/reffering URLs. However, this means that if I open my mail and re-read it from another computer, it counts as a forward. Any ideas on this one? To summarize: Litmus Email Analytics says they can track email reads, skims, glanced/deleted, prints and forwards. How do they do it (skims, glanced/deleted and forwards)?

  • Why is floating point byte swapping different from integer byte swapping?

    - by CJ
    I have a binary file of doubles that I need to load using C++. However, my problem is that it was written in big-endian format but the fstream operator will then read the number wrong because my machine is little-endian. It seems like a simple problem to resolve for integers, but for doubles and floats the solutions I have found won't work. How can I (or should I) fix this? I read this as a reference for integer byte swapping: http://stackoverflow.com/questions/105252/how-do-i-convert-between-big-endian-and-little-endian-values-in-c

  • Some clarification needed about synchronous versus asynchronous asio operations

    - by Old newbie
    As far as I know, the main difference between synchronous and asynchronous operations. I.e. write() or read() vs async_write() and async_read() is that the former, don't return until the operation finish -or error-, and the last ones, returns inmediately. Due the fact that the asynchronous operations are controlled by an io_service.run() that does not finish until the controlled operations has finalized. It seems to me that in sequencial operations as those involved in TCP/IP connections with protocols such as POP3, in which the operaton is a sequence such as: C: <connect> S: Ok. C: User... S: Ok. C: Password S: Ok. C: Command S: answer C: Command S: answer ... C: bye S: <close> The difference between synchronous/asynchronous opperatons does not make much sense. Of course, in both operations there is allways the risk that the program flow stops indefinitely by some circunstance -there the use of timers-, but I would like know some more authorized opinions in this matter. I must admit that the question is rather ill-defined, but I like hear some advices about when use one or other, because I've problems in debugging with MS Visual Studio, asynchronous SSL operations in a POP3 client in wich I'm working now -about some of who surely I would write here soon-, and sometimes think that perhaps is a bad idea use asynchronous in this. Not to say that I'm an absolute newbie with this librarys, that additionally to the difficult with the idioma, and some obscure concepts in the STL, must suffer the brevity of the asio documentation.

  • Java Socket Disconnect Reporting vs. C# Disconnection

    - by ikurtz
    in C# when a sockets connection is terminated the other node is informed of this before terminating the link thus the remaning node can update the connection status. in Java when i terminate a communication link the other node keeps reporting the connection as valid. do i need to implement a read cycle (makes sense) that reports the connection as lost when it recieves a -1 during read (in C# this is 0 i think)? thank you for your insight. EDIT: thanks to you both. as i suspected and mentioned in my post that an additional check is required to confirm the connected state of a connection.

  • Parsing files with python

    - by iHeartDucks
    My input file is going to be something like this key "value" key "value" ... the above lines repeat What I do is read the file contents, populate an object with the data and return it. There are only a set number of keys that can be present in the file. Since I am a beginner in python, I feel that my code to read the file is not that good My code is something like this ObjInstance = CustomClass() fields = ['key1', 'key2', 'key3'] for field in fields: for line in f: if line.find(field) >= 0: if pgn_field == 'key1': objInstance.DataOne = get_value_using_re(line) elif pgn_field == 'key2': objInstance.DataTwo = get_value_using_re(line) return objInstance; The function "get_value_using_re" is very simple, it looks for a string in between the double quotes and returns it. I fear that I will have multiple if elif statements and I don't know if this is the right way or not. Am I doing the right thing here?

  • Logging exceptions to database in NServiceBus

    - by IGoor
    If an exception occurs in my MessageHandler I want to write the exception details to my database. How do I do this? Obviously, I cant just catch the exception, write to database, and rethrow it since NSB rollbacks all changes. (IsTransactional is set to true) I tried adding logging functionality in a seperate handler, which I caledl using SendLocal if an exception occured, but this does not work: public void Handle(MessageItem message) { try { DoWork(); } catch(Exception exc) { Bus.SendLocal(new ExceptionMessage(exc.Message)); throw; } } I also tried using Log4Net with a custom appender, but this also rolled back. Configure.With() .Log4Net<DatabaseAppender>(a => a.Log = "Log") appender: public class DatabaseAppender : log4net.Appender.AppenderSkeleton { public string Log { get; set; } protected override void Append(log4net.Core.LoggingEvent loggingEvent) { if (loggingEvent.ExceptionObject != null) WriteToDatabase(loggingEvent.ExceptionObject); } } Is there anyway to log unhandled exceptions in the messagehandler when IsTransactional is true? Thanks in advance.

  • hibernate formula with column

    - by coolguy
    I have a table with a column that will be encrypted by a trigger after the record is inserted. When I read the column, I need to apply a decrypt function in the hibernate domain class. While saving the object, the value of the column will be saved as such. While reading the column, apply a database function on the read data. @Formula and @Column annotation cannot be applied to an attribute in the entity class. How do I achieve this functionality without using one attribute for saving and another one with @Formula for reading it?

  • Move options between multiple lists

    - by Martha
    We currently have a form with the standard multi-select functionality of "here are the available options, here are the selected options, here are some buttons to move stuff back and forth." However, the client now wants the ability to not just select certain items, but to also categorize them. For example, given a list of books, they want to not just select the ones they own, but also the ones they've read, the ones they would like to read, and the ones they've heard about. (All examples fictional.) Thankfully, a selected item can only be in one category at a time. I can find many examples of moving items between listboxes, but not a single one for moving items between multiple listboxes. To add to the complication, the form needs to have two sets of list+categories, e.g. a list of movies that need to be categorized in addition to the aforementioned books. EDIT: Having now actually sat down to try to code the non-javascripty bits, I need to revise my question, because I realized that multiple select lists won't really work from the "how do I inform the server about all this lovely new information" standpoint. So the html code is now a pseudo-listbox, i.e. an unordered list (ul) displayed in a box with a scrollbar, and each list item (<li>) has a set of five radio buttons (unselected/own/read/like/heard). My task is still roughly the same: how to take this one list and make it easy to categorize the items, in such a way that the user can tell at a glance what is in what category. (The pseudo-listbox has some of the same disadvantages as a multi-select listbox, namely it's hard to tell what's selected if the list is long enough to scroll.) The dream solution would be a drag-and-drop type thing, but at this point even buttons would be OK. Another modification (a good one) is that the client has revised the lists, so the longest is now "only" 62 items long (instead of the many hundreds they had before). The categories will still mostly contain zero, one, or two selected items, possibly a couple more if the user was overzealous. As far as OS and stuff, the site is in classic asp (quit snickering!), the server-side code is VBScript, and so far we've avoided the various Javascript libraries by the simple expedient of almost never using client-side scripting. This one form for this one client is currently the big exception. Give 'em an inch and they want a mile... Oh, and I have to add: I suck at Javascript, or really at any C-descendant language. Curly braces give me hives. I'd really, really like something I can just copy & paste into my page, maybe tweak some variable names, and never look at it again. A girl can dream, can't she? :) [existing code deleted because it's largely irrelevant.]

  • ASP.NET: How to get same validators control to be both client-side and server-side

    - by harrije
    Hello, For the ASP.NET validator controls, I want to use both client-side validation for the user experience and server-side validation to guard against hackers. ASP.NET documentation leads me to believe that if EnableClientScript="True" then there will be no server-side validation if client-side validation is possible for the user agent. To get server-side validation, the documentation says use EnableClientScript="False", which bypasses client-side validation altogether. Am I misunderstanding how the validator controls work? I ask because it seems obvious that many developers would want both client and server side validation together, and I find it hard to believe both together is not possible with one of the standard validation controls. If I am understanding the ASP.NET documentation correctly, then I can find only two options: Use two validator controls exactly the same except for their ID and EnableClientScript properties. Obviously ugly for maintaining two controls almost the same. Write some code behind to check if postback then invoke the Validate method on the validator group. Why write code behind if there a way to be automatic from the control? Is there a way to do so using a single validator control with no code behind? Thanks in advance for your input.

  • How to share a variable between two classes?

    - by Altefquatre
    How would you share the same object between two other objects? For instance, I'd like something in that flavor: class A { private string foo_; // It could be any other class/struct too (Vector3, Matrix...) public A (string shared) { this.foo_ = shared; } public void Bar() { this.foo_ = "changed"; } } ... // inside main string str = "test"; A a = new A(str); Console.WriteLine(str); // "test" a.Bar(); Console.WriteLine(str); // I get "test" instead of "changed"... :( I read there is some ref/out stuff, but I couldn't get what I'm asking here. I could only apply some changes in the methods scope where I was using ref/out arguments... I also read we could use pointers, but is there no other way to do it?

  • Converting an AnsiString to a Unicode String

    - by jrodenhi
    I'm converting a D2006 program to D2010. I have a value stored in a single byte per character string in my database and I need to load it into a control that has a LoadFromStream, so my plan was to write the string to a stream and use that with LoadFromStream. But it did not work. In studying the problem, I see an issue that tells me that I don't really understand how conversion from AnsiString to Unicode string works. Here is some code I am puzzling over: oStringStream := TStringStream.Create(sBuffer); sUnicodeStream := oPayGrid.sStream; //explicit conversion to unicode string iSize1 := StringElementSize(oPaygrid.sStream); iSize2 := StringElementSize(sUnicodeStream); oStringStream.WriteString(sUnicodeStream); When I get to the last line, iSize1 does equal 1 and iSize2 does equal 2, so that part is what I understood from my reading. But, on the last line, after I write the string to the stream, and look at the Bytes Property of the string, it shows this (the string starts as '16,159'): (49 {$31}, 54 {$36}, 44 {$2C}, 49 {$31}, 53 {$35}, 57 {$39} ... I was expecting that it might look something like (49 {$31}, 00 {$00}, 54 {$36}, 00 {$00}, 44 {$2C}, 00 {$00}, 49 {$31}, 00 {$00}, 53 {$35}, 00 {$00}, 57 {$39}, 00 {$00} ... I'm not getting the right results out of the LoadFromStream because it is reading from the stream two bytes at a time, but the data it is receiving is not arranged that way. What is it that I should do to give the LoadFromStream a well formed stream of data based on a unicode string? Thank you for your help.

  • Need Help finding an appropriate task asignment algoritm for a collage project involving coordinatin

    - by Trif Mircea
    Hello. I am a long time lurker here and have found over time many answers regarding jquery and web development topics so I decided to ask a question of my own. This time I have to create a c++ project for collage which should help manage the workflow of a company providing all kinds of services through in the field teams. The ideas I have so far are: client-server application; the server is a dispatcher where all the orders from clients get and the clients are mobile devices (PDAs) each team in the field having one a order from a client is a task. Each task is made up of a series of subtasks. You have a database with estimations on how long a task should take to complete you also know what tasks or subtasks each team on the field can perform based on what kind of specialists made up the team (not going to complicate the problem by adding needed materials, it is considered that if a member of a team can perform a subtask he has the stuff needed) Now knowing these factors, what would a good task assignment algorithm be? The criteria is: how many tasks can a team do, how many tasks they have in the queue, it could also be location, how far away are they from the place but I don't think I can implement that.. It needs to be efficient and also to adapt quickly is the human dispatcher manually assigns a task. Any help or leads would be really appreciated. Also I'm not 100% sure in the idea so if you have another way you would go about creating such an application please share, even if it just a quick outline. I have to write a theoretical part too so even if the ideas are far more complex that what i outlined that would be ok ; I'd write those and implement what I can.

  • Model-binding an object from the repository by several keys

    - by Anton
    Suppose the following route: {region}/{storehouse}/{controller}/{action} These two parameters region and storehouse altogether identify a single entity - a Storehouse. Thus, a bunch of controllers are being called in the context of some storehouse. And I'd like to write actions like this: public ActionResult SomeAction(Storehouse storehouse, ...) Here I can read your thoughts: "Write custom model binder, man". I do. However, the question is How to avoid magic strings within custom model binder? Here is my current code: public class StorehouseModelBinder : IModelBinder { readonly IStorehouseRepository repository; public StorehouseModelBinder(IStorehouseRepository repository) { this.repository = repository; } public object BindModel(ControllerContext controllerContext, ModelBindingContext bindingContext) { var region = bindingContext.ValueProvider.GetValue("region").AttemptedValue; var storehouse = bindingContext.ValueProvider.GetValue("storehouse").AttemptedValue; return repository.GetByKey(region, storehouse); } } If there was a single key, bindingContext.ModelName could be used... Probably, there is another way to supply all the actions with a Storehouse object, i.e. declaring it as a property of the controller and populating it in the Controller.Initialize.
