  • How can I log and retrieve error messages from a client-side desktop app?

    - by KeyboardMonkey
    Update: The service-based answers below are most likely the way to go, I am also curious to see if there are any out-the-box solutions anyone has tried in the field. Our system uses a client-server architecture, and with more clients using it I'm thinking of better ways to log client application errors, and get them sent to us. Currently we just show a simple error message, with a button that preps an email (with the default system email client) and the clients send this on to our support address. This contains extra info like the stack trace. We also tried saving errors to a network share in the company, but I'm not too keen on that archaic solution either. Now there are only two businesses that refer to clients as users, and I'm sure some of ours support both lifestyles, as they just ignore the email button, and sends a full screen-shot wrapped nicely in a word document. Some factors I'm thinking of include A solution to log errors, like the contrived one above, A robust solution; Logging to a SQL database won't work; if that fails too, then what? Is at least semi-automated, preferably to the point where the logs reach my side. It copes with load, our client base is growing and the current solution, and our inboxes, won't hold up. Minimise installing extra 3rd party components on clients, I want to keep the SPOF to a min. I'd love to hear about any experience or suggestions you have on how I can implement such a solution. System Details It's a Microsoft .Net 2 based system with a SQL backend. Some users work remotely over the net, so network shares aren't always available (unless they VPN, which is awesomely slow at any rate). We have users across different companies, their DB's are hosted on-site. We have remote access to 90% of them.

  • cocoa - making a UIImageView class act like a UIButton

    - by Mike
    For some reason that will take too much time to explain, I have to create a UIImageView based class that has some properties of a button. Imagine a class like the UISwitch (no I cannot base my class on the UISwitch) with two states, on and off. WHen the user selects one state, it runs a method like a button that was clicked and the method receives the sender id. I have already the class more or less working. The class is based on UIImageView. I am having difficulties to understand the following. WHen I create a new button I have a line that is like [myButton addTarget:self action:NSSelectorFromString(myMethod) forControlEvents:UIControlEventTouchUpInside]; This line defines a target and an action to run when the button is triggered. I my case I would need something like [myObject addTarget:self action:myMethod ifState:1] //or another thing ifState:2 I have no idea what kind of code I should put on the class to make this work. Remember that as a button the class should send the "sender" information to identify the object which triggered the action... Can you guys, transcendental gurus help? thanks for any help!

  • Is there any danger in calling free() or delete instead of delete[]? [closed]

    - by Matt Joiner
    Possible Duplicate: ( POD )freeing memory : is delete[] equal to delete ? Does delete deallocate the elements beyond the first in an array? char *s = new char[n]; delete s; Does it matter in the above case seeing as all the elements of s are allocated contiguously, and it shouldn't be possible to delete only a portion of the array? For more complex types, would delete call the destructor of objects beyond the first one? Object *p = new Object[n]; delete p; How can delete[] deduce the number of Objects beyond the first, wouldn't this mean it must know the size of the allocated memory region? What if the memory region was allocated with some overhang for performance reasons? For example one could assume that not all allocators would provide a granularity of a single byte. Then any particular allocation could exceed the required size for each element by a whole element or more. For primitive types, such as char, int, is there any difference between: int *p = new int[n]; delete p; delete[] p; free p; Except for the routes taken by the respective calls through the delete-free deallocation machinery?

  • jQuery changing fields to substring of related field

    - by Katherine
    Another jquery calculation question. I've this, which is sample code from the plugin site that I am playing with to get this working: function recalc(){ $("[id^=total_item]").calc( "qty * price", { qty: $("input[name^=qty_item_]"), price: $("input[name^=price_item_]"), }, function (s){ return s.toFixed(2);}, function ($this){ var sum = $this.sum(); $("#grandTotal").val( // round the results to 2 digits sum.toFixed(2) ); } ); } Changes in the price fields cause the totals to update: $("input[name^=price_item_]").bind("keyup", recalc); recalc(); Problem is I won't know the value of the price fields, they will be available to me only as a substring of values entered by the user, call it 'itemcode'. There will be a variable number of items, based on a php query. I've come up with this to change the price based on the itemcode: $("input[name^='itemcode_item_1']").keyup(function () { var codeprice = this.value.substring(2,6); $("input[name^='price_item_1']").val(codeprice); }); $("input[name^='itemcode_item_2']").keyup(function () { var codeprice = this.value.substring(2,6); $("input[name^='price_item_2']").val(codeprice); }); However while it does that, it also stops the item_total from updating. Also, I feel there must be a way to not need to write a numbered function for each item on the list. However when I just use $("input[name^='itemcode_item_']") updating any itemcode field updates all price fields, which is not good. Can anyone point me in the right direction? I know I am a bit clueless here, but javascript of any kind is not my thing.

  • How to make dynamically generated .net service client read configuration from another location than

    - by Bryan
    Hi, I've currently written code to use the ServiceContractGenerator to generate web service client code based on a wsdl, and then compile it into an assembly in memory using the code dom. I'm then using reflection to set up the binding, endpoint, service values/types, and then ultimately invoke the web service method based on xml configuration that can be altered at run time. This all currently works fine. However, the problem I'm currently running into, is that I'm hitting several exotic web services that require lots of custom binding/security settings. This is forcing me to add more and more configuration into my custom xml configurations, as well as the corresponding updates to my code to interpret and set those binding/security settings in code. Ultimately, this makes adding these 'exotic' services slower, and I can see myself eventually reimplementing the 'system.serviceModel' section of the web or app.config file, which is never a good thing. My question is, and this is where my lack of experience .net and C# shows, is there a way to define the configuration normally found in the web.config or app.config 'system.serviceModel' section somewhere else, and at run time supply this to configuration to the web service client? Is there a way to attach an app.config directly to an assembly as a resource or any other way to supply this configuration to the client? Basically, I'd like attach an app.config only containing a 'system.serviceModel' to the assembly containing a web service client so that it can use its configuration. This way I wouldn't need to handle every configuration under the sun, I could let .net do it for me. Fyi, it's not an option for me to put the configuration for every service in the app.config for the running application. Any help would be greatly appreciated. Thanks in advance! Bryan

  • Advice for Windows XP Scripting, WSH versus PowerShell

    - by Greg Graham
    After much experience scripting in the Unix/Linux open-source world, using languages such as Bourne Shell, Perl, Python, and Ruby, I now find myself needing to do some Windows XP admin scripting. It appears that the legacy environment is Windows Script Host (WSH), which can use various scripting languages, but the primary language is VBScript, and is based on COM objects. However, the future appears to be Windows PowerShell, which is based on .NET. I haven't done Basic since Applesoft in the 70s, so I'm not keen on learning VBScript, although I did learn enough to write a small script to mount network drives. If I'm going to spend time to really learn this, I'm leaning towards investing my time in the .NET PowerShell environment, if it truly is the future. I did some C# Windows Forms programming a couple of years ago, so I have some exposure to .NET, which also makes PowerShell attractive. Understanding that no one has a crystal ball to predict the future of Microsoft, I would like hear from anyone who is a PowerShell user and thinks it's worthwhile, or if there is anyone that knows of serious drawbacks to PowerShell, and recommends that I stay away from it. Update: I ended up using WSH/VBScript for a particular script that I am installing as a startup script on user's Windows XP workstations. All I have to do is copy it to their Startup folder, and I'm done. However, I only learned enough WSH to accomplish this one job. I am glad to see that PowerShell is the future, and when I have more complicated scripting tasks, I'll to turn PowerShell.

In PageHeader.ascx, i have an asp.net substitution control, where i want to show some links based on the logged in user. <%@ Control Language="C#" AutoEventWireup="true" CodeBehind="PageHeader.ascx.cs" Inherits="MyProject.Lib.UserControls.PageHeader1" %> <div class="headerRow"> <div class="headerLogo"> <a href="Default.aspx"><img src="Lib/Images/header.gif" alt=""></a> </div> <div id="divHeaderMenu" runat="server"> <asp:Substitution ID="subLinks" runat="server" MethodName="GetUserProfileHeaderLinks" /> </div> </div><!--headerRow--> In my ascx.cs file,i have a static method which will return a string based on whether the used logged in or not using session public static string GetUserProfileHeaderLinks(HttpContext context) { string strHeaderLinks = string.Empty; // check session and return string return strHeaderLinks; } But Still the page shows the same content for both logged in user and Guest user. My objective is to to have the Page being cached except the content inside the substitution control. Any idea how to achieve this ? Thanks in advance

  • One Model to Rule Them All - VS2010 UML, ADO.NET Entity Data Model, and T4

    - by Eric J.
    I worked on a fairly large project a while back where we modeled the classes in Enterprise Architect and generated the (partial) POCO classes (complete with model-driven business rule validations), persistence (NHibernate mapping file) and DDL. Based on certain model attributes we could flag alternate generation strategies or indicate that a particular portion would be entirely hand-coded. There was a good deal of initial investment, but it paid large dividends over the lifetime of a 15 developer, 3 year project. I'm investigating doing something similar with the current Microsoft technology stack. The place I'm stuck is that class modeling is done with the VS 2010 UML tools, but logical data modeling is done with Entity Data Modeler. Is it a reasonable path to use VS 2010 UML as the "single source of truth" and code generate the edmx files based on the class model? That's the inverse of the common path to create the entity model and use a POCO generator to generate classes. However, a good class model can be used to generate much more than just the properties so I tend to view it as a better choice than the entity model.

  • iPhone app doesn't build crash reports

    - by BankStrong
    My app formerly created useful crash logs. I synced my iPhone in the past and found crash logs in library/logs/CrashReporter About a month ago, my app stopped creating crash reports. When I first discovered this problem, I assumed it was due to memory corruption (a possibility in my app). I just created a new project and added a crash to it. // Implement viewDidLoad to do additional setup after loading the view, // typically from a nib. - (void)viewDidLoad { NSMutableArray *array = [[NSMutableArray alloc] init]; [array removeObjectAtIndex:-1]; [super viewDidLoad]; } This app does not create a crash report either. Ideas I've started to explore: My phone is corrupted (tried restoring - somehow I brought it to the state from a few months ago) My XCode is corrupt (tried reinstalling, but current download demands Snow Leopard - and I can't upgrade to Snow Leopard online). This seems possible - I may have messed with device support around a month ago (similar to http://stackoverflow.com/questions/1224867/does-iphone-os-3-0-1-ruin-your-development-phone ) The location for crash logs has somehow moved. Suggestions?

  • Software development metrics and reporting

    - by David M
    I've had some interesting conversations recently about software development metrics, in particular how they can be used in a reasonably large organisation to help development teams work better. I know there have been Stack Overflow questions about which metrics are good to use - like this one, but my question is more about which metrics are useful to which stakeholders, and at what level of aggregation. As an example, my view is that code coverage is a useful metric in the following ways (and maybe others): For a team's own internal use when combined with other measurements. For facilitating/enabling/mentoring teams, where it might be instructive when considered on a team-by-team basis as a trend (e.g. if team A and B have coverage this month of 75 and 50, I'd be more concerned with team A than B if the previous month they'd had 80 and 40). For senior management when presented as an aggregated statistic across a number of teams or a whole department. But I don't think it's useful for senior management to see this on a team-by-team basis, as this encourages artifical attempts to bolster coverage with tests that merely exercise, rather than test, code. I'm in an organisation with a couple of levels in its management hierarchy, but where the vast majority of managers are technically minded and able (with many still getting their hands dirty). Some of the development teams are leading the way in driving towards agile development practices, but others lag, and there is now a serious mandate from the top for this to be the way the organisation works. A couple of us are starting a programme to encourage this. In this sort of an organisation, what sort of metrics do you think are useful, to whom, why, and at what level of aggregation? I don't want people to feel their performance is being assessed based on a metric that they can artificially influence; at the same time, the senior management are going to want some sort of evidence that progress is being made. What advice or caveats can you provide based on experience in your own organisations? EDIT We are definitely wanting to use metrics as a tool for organisational improvement not as a tool for individual performance measurement.

  • Javscript closure questions

    - by Shuchun Yang
    While I was reading the book Javascript: The Good Parts. I can not understand the piece of code bellow: We can generalize this by making a function that helps us make memoized functions. The memoizer function will take an initial memo array and the fundamental function. It returns a shell function that manages the memo store and that calls the fundamental function as needed. We pass the shell function and the function's parameters to the fundamental function: var memoizer = function (memo, fundamental) { var shell = function (n) { var result = memo[n]; if (typeof result !== 'number') { result = fundamental(shell, n); memo[n] = result; } return result; }; return shell; }; We can now define fibonacci with the memoizer, providing the initial memo array and fundamental function: var fibonacci = memoizer([0, 1], function (test, n) { return test(n - 1) + test(n - 2); }); My question is what is the test function? When does it get defined and invoked? It seems very confusing to me. Also I think this statement: memo[n] = result; is useless. Please correct if I am wrong.

  • jQuery - dynamic variables?

    - by user331884
    Newbie question. Given the following html. <div id="mycontainer1" class="container"> <input type="text" class="name"/> <input type="text" class="age"/> </div> <div id="mycontainer2" class="container"> <input type="text" class="name"/> <input type="text" class="age"/> <input type="text" class="address"/> </div> I'm trying to create a function where I can pass an element id and an array that contains the classes of the input values I want to get. So for example, var inputClasses = ['name','age']; getInputValue('#myContainer1', inputClasses); function getInputValue(elem, arr) { var temp = {}; $(elem).each(function() { // need a way to map items in array to variables // but how do I do this dynamically? var nameValue = $(this).find('.name').val(); var ageValue = $(this).find('.age').val(); });

  • J2ME web service client

    - by Wasim
    Hi all , I started to use the Netbeans 6.8 web service client wizard . I created a web service (.Net web service) witch return an object Data. The Data class , contains fileds with many types : int , string , double , Person object and array of Person object. I created the J2ME client code through the wizard and every thing seems ok . I see in the Netbeans project the service and the stub . When I try to call my web service method , say Data GetData() ; Then I have a problem with parsing the returned data from the web service and the client data object . As follows : After finishing to call the web service method , in the stub code : public Data helloWorld() throws java.rmi.RemoteException { Object inputObject[] = new Object[] { }; Operation op = Operation.newInstance( _qname_operation_HelloWorld, _type_HelloWorld, _type_HelloWorldResponse ); _prepOperation( op ); op.setProperty( Operation.SOAPACTION_URI_PROPERTY, "http://tempuri.org/HelloWorld" ); Object resultObj; try { resultObj = op.invoke( inputObject ); } catch( JAXRPCException e ) { Throwable cause = e.getLinkedCause(); if( cause instanceof java.rmi.RemoteException ) { throw (java.rmi.RemoteException) cause; } throw e; } return Data_fromObject((Object[])resultObj); } private static Data Data_fromObject( Object obj[] ) { if(obj == null) return null; Data result = new Data(); result.setIntData(((Integer )obj[0]).intValue()); result.setStringData((String )obj[1]); result.setDoubleData(((Double )obj[2]).doubleValue()); return result; } I debug the code and in Run time resultObj has one element witc is an array of the Data object , so in parsing the values in the Data_fromObject method it expect many cells like we see in the code obj[0] , obj[1] , obj [2] but in realtime it has obj[0][0] , obj[0][1] , obj[0][2] What can be the problem , how can check the code generation issue ? Is it a problem with the web service side. Please help. Thanks in advance...

  • Looking for ideas how to refactor my (complex) algorithm

    - by _simon_
    I am trying to write my own Game of Life, with my own set of rules. First 'concept', which I would like to apply, is socialization (which basicaly means if the cell wants to be alone or in a group with other cells). Data structure is 2-dimensional array (for now). In order to be able to move a cell to/away from a group of another cells, I need to determine where to move it. The idea is, that I evaluate all the cells in the area (neighbours) and get a vector, which tells me where to move the cell. Size of the vector is 0 or 1 (don't move or move) and the angle is array of directions (up, down, right, left). This is a image with representation of forces to a cell, like I imagined it (but reach could be more than 5): Let's for example take this picture: Forces from lower left neighbour: down (0), up (2), right (2), left (0) Forces from right neighbour : down (0), up (0), right (0), left (2) sum : down (0), up (2), right (0), left (0) So the cell should go up. I could write an algorithm with a lot of if statements and check all cells in the neighbourhood. Of course this algorithm would be easiest if the 'reach' parameter is set to 1 (first column on picture 1). But what if I change reach parameter to 10 for example? I would need to write an algorithm for each 'reach' parameter in advance... How can I avoid this (notice, that the force is growing potentialy (1, 2, 4, 8, 16, 32,...))? Can I use specific design pattern for this problem? Also: the most important thing is not speed, but to be able to extend initial logic. Things to take into consideration: reach should be passed as a parameter i would like to change function, which calculates force (potential, fibonacci) a cell can go to a new place only if this new place is not populated watch for corners (you can't evaluate right and top neighbours in top-right corner for example)

  • Android : Bitmap save to location

    - by Chrispix
    I am working on a function to download an image from a web server, redisplay it on the screen, and if the user wishes to keep the image, save it on the SD card in a certain folder. Is there an easy way to take a bitmap and just save it to the SD card in a folder of my choice? My issue is that I can download the image, display it on screen as a Bitmap. The only way I have been able to find to save an image to a particular folder is to use FileOutputStream, but that requires a byte array. I am not sure how to convert (if this is even the right way) from Bitmap to byte array, so I can use a Fileoutput stream to write the data. The other option I have is it use MediaStore : MediaStore.Images.Media.insertImage(getContentResolver(), bm, barcodeNumber + ".jpg Card Image", barcodeNumber + ".jpg Card Image"); Which works fine to save to SD card, but does not allow you to customize the folder. Any assistance would be very much appreciated. Thank you in advance.

  • Scalable / Parallel Large Graph Analysis Library?

    - by Joel Hoff
    I am looking for good recommendations for scalable and/or parallel large graph analysis libraries in various languages. The problems I am working on involve significant computational analysis of graphs/networks with 1-100 million nodes and 10 million to 1+ billion edges. The largest SMP computer I am using has 256 GB memory, but I also have access to an HPC cluster with 1000 cores, 2 TB aggregate memory, and MPI for communication. I am primarily looking for scalable, high-performance graph libraries that could be used in either single or multi-threaded scenarios, but parallel analysis libraries based on MPI or a similar protocol for communication and/or distributed memory are also of interest for high-end problems. Target programming languages include C++, C, Java, and Python. My research to-date has come up with the following possible solutions for these languages: C++ -- The most viable solutions appear to be the Boost Graph Library and Parallel Boost Graph Library. I have looked briefly at MTGL, but it is currently slanted more toward massively multithreaded hardware architectures like the Cray XMT. C - igraph and SNAP (Small-world Network Analysis and Partitioning); latter uses OpenMP for parallelism on SMP systems. Java - I have found no parallel libraries here yet, but JGraphT and perhaps JUNG are leading contenders in the non-parallel space. Python - igraph and NetworkX look like the most solid options, though neither is parallel. There used to be Python bindings for BGL, but these are now unsupported; last release in 2005 looks stale now. Other topics here on SO that I've looked at have discussed graph libraries in C++, Java, Python, and other languages. However, none of these topics focused significantly on scalability. Does anyone have recommendations they can offer based on experience with any of the above or other library packages when applied to large graph analysis problems? Performance, scalability, and code stability/maturity are my primary concerns. Most of the specialized algorithms will be developed by my team with the exception of any graph-oriented parallel communication or distributed memory frameworks (where the graph state is distributed across a cluster).

  • How to replace openSSL calls with C# code?

    - by fonix232
    Hey there again! Today I ran into a problem when I was making a new theme creator for chrome. As you may know, Chrome uses a "new" file format, called CRX, to manage it's plugins and themes. It is a basic zip file, but a bit modified: "Cr24" + derkey + signature + zipFile And here comes the problem. There are only two CRX creators, written in Ruby or Python. I don't know neither language too much (had some basic experience in Python though, but mostly with PyS60), so I would like to ask you to help me convert this python app to a C# code that doesn't depend on external programs. Also, here is the source of crxmake.py: #!/usr/bin/python # Cribbed from http://github.com/Constellation/crxmake/blob/master/lib/crxmake.rb # and http://src.chromium.org/viewvc/chrome/trunk/src/chrome/tools/extensions/chromium_extension.py?revision=14872&content-type=text/plain&pathrev=14872 # from: http://grack.com/blog/2009/11/09/packing-chrome-extensions-in-python/ import sys from array import * from subprocess import * import os import tempfile def main(argv): arg0,dir,key,output = argv # zip up the directory input = dir + ".zip" if not os.path.exists(input): os.system("cd %(dir)s; zip -r ../%(input)s . -x '.svn/*'" % locals()) else: print "'%s' already exists using it" % input # Sign the zip file with the private key in PEM format signature = Popen(["openssl", "sha1", "-sign", key, input], stdout=PIPE).stdout.read(); # Convert the PEM key to DER (and extract the public form) for inclusion in the CRX header derkey = Popen(["openssl", "rsa", "-pubout", "-inform", "PEM", "-outform", "DER", "-in", key], stdout=PIPE).stdout.read(); out=open(output, "wb"); out.write("Cr24") # Extension file magic number header = array("l"); header.append(2); # Version 2 header.append(len(derkey)); header.append(len(signature)); header.tofile(out); out.write(derkey) out.write(signature) out.write(open(input).read()) os.unlink(input) print "Done." if __name__ == '__main__': main(sys.argv) Please could you help me?

  • Best pattern for storing (product) attributes in SQL Server

    - by EdH
    We are starting a new project where we need to store product and many product attributes in a database. The technology stack is MS SQL 2008 and Entity Framework 4.0 / LINQ for data access. The products (and Products Table) are pretty straightforward (a SKU, manufacturer, price, etc..). However there are also many attributes to store with each product (think industrial widgets). These may range from color to certification(s) to pipe size. Every product may have different attributes, and some may have multiples of the same attribute (Ex: Certifications). The current proposal is that we will basically have a name/value pair table with a FK back to the product ID in each row. An example of the attributes Table may look like this: ProdID AttributeName AttributeValue 123 Color Blue 123 FittingSize 1.25 123 Certification AS1111 123 Certification EE2212 123 Certification FM.3 456 Pipe 11 678 Color Red 999 Certification AE1111 ... Note: Attribute name would likely come from a lookup table or enum. So the main question here is: Is this the best pattern for doing something like this? How will the performance be? Queries will be based on a JOIN of the product and attributes table, and generally need many WHEREs to filter on specific attributes - the most common search will be to find a product based on a set of known/desired attributes. If anyone has any suggestions or a better pattern for this type of data, please let me know. Thanks! -Ed

  • What is the most platform- and Python-version-independent way to make a fast loop for use in Python?

    - by Statto
    I'm writing a scientific application in Python with a very processor-intensive loop at its core. I would like to optimise this as far as possible, at minimum inconvenience to end users, who will probably use it as an uncompiled collection of Python scripts, and will be using Windows, Mac, and (mainly Ubuntu) Linux. It is currently written in Python with a dash of NumPy, and I've included the code below. Is there a solution which would be reasonably fast which would not require compilation? This would seem to be the easiest way to maintain platform-independence. If using something like Pyrex, which does require compilation, is there an easy way to bundle many modules and have Python choose between them depending on detected OS and Python version? Is there an easy way to build the collection of modules without needing access to every system with every version of Python? Does one method lend itself particularly to multi-processor optimisation? (If you're interested, the loop is to calculate the magnetic field at a given point inside a crystal by adding together the contributions of a large number of nearby magnetic ions, treated as tiny bar magnets. Basically, a massive sum of these.) # calculate_dipole # ------------------------- # calculate_dipole works out the dipole field at a given point within the crystal unit cell # --- # INPUT # mu = position at which to calculate the dipole field # r_i = array of atomic positions # mom_i = corresponding array of magnetic moments # --- # OUTPUT # B = the B-field at this point def calculate_dipole(mu, r_i, mom_i): relative = mu - r_i r_unit = unit_vectors(relative) #4pi / mu0 (at the front of the dipole eqn) A = 1e-7 #initalise dipole field B = zeros(3,float) for i in range(len(relative)): #work out the dipole field and add it to the estimate so far B += A*(3*dot(mom_i[i],r_unit[i])*r_unit[i] - mom_i[i]) / sqrt(dot(relative[i],relative[i]))**3 return B

  • Environment variable in xcconfig won't expand in Settings.bundle/Root.plist

    - by AO
    I have defined my own environment variable in a .xcconfig file and based my configurations on that as described at http://www.silverchairsolutions.com/blog/2008/03/automating-cocoa-deployments-with-sparkle-and-xcode. My environment variable is indeed expanded in Info.plist but not in my Settings.bundle/Root.plist. Why won't it expand there? Root.plist looks like this: <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>Title</key> <string>${PRODUCT_NAME}</string> <key>PreferenceSpecifiers</key> <array> <dict> <key>DefaultValue</key> <string>${PRODUCT_NAME}</string> <key>Key</key> <string>version</string> <key>Title</key> <string>Version</string> <key>Type</key> <string>PSTitleValueSpecifier</string> </dict> <dict> <key>DefaultValue</key> <string></string> <key>Key</key> <string>atc</string> <key>Title</key> <string>ATC</string> <key>Type</key> <string>PSTitleValueSpecifier</string> </dict> </array>

  • Java NIO (Netty): How does Encryption or GZIPping work in theory (with filters)

    - by Tom
    Hello Experts, i would be very thankfull if you can explain to me, how in theory the "Interceptor/Filter" Pattern in ByteStreams (over Sockets/Channels) work (in Asynchronous IO with netty) in regard to encryption or compression of data. Given I have a Filter that does GZIPPING. How is this internally implemented? Does the Filter "collect" so many bytes form the channel, that this is a usefull number of bytes that can then be en/decoded? What is in general the minimal "blocksize(data to encode/decode in a chunk)" of socket based gzipping? Does this "blocksize" have to be negotiated in advance between server and client? What happens if the client does not send enough data to "fill" the blocksize (due to a network conquestion) but does not close the connection. Does this mean the other side will simply wait until it gets enough bytes to decode or until a timeout occoures...How is the Filter pattern the applied? The compression filter will de/compress the blocksize of bytes and then store them again in the same buffer would (in the case of netty) i normally be using the ChannelHanlderContext to pass the de/encoded data to the next filter?... Any explanations/links/tutorials (for beginners;-) will be very much appreciated to help me understand how for example encryption/compressing are implemented in socket based communication with filters/interceptor pattern. thank you very much tom

  • Setting ivar in objective-c from child view in the iPhone

    - by Ivan
    Hi there! Maybe a FAQ at this website. I have a TableViewController that holds a form. In that form I have two fields (each in it's own cell): one to select who paid (single selection), and another to select people expense is paid for (multiple selection). Both fields open a new TableViewController included in an UINavigationController. Single select field (Paid By) holds an object Membership Multiple select field (Paid For) holds an object NSMutableArray Both vars are being sent to the new controller identically the same way: mySingleSelectController.crSelectedMember = self.crPaidByMember; myMultipleSelectController.crSelectedMembers = self.crSelectedMembers; From Paid for controller I use didSelectAtIndexPath method to set a mutable array of Memberships for whom is paid: if ([[tableView cellForRowAtIndexPath:indexPath] accessoryType] == UITableViewCellAccessoryCheckmark) { [self.crSelectedMembers removeObject:[self.crGroupMembers objectAtIndex:indexPath.row]]; //... } else { [self.crSelectedMembers addObject:[self.crGroupMembers objectAtIndex:indexPath.row]]; //... } So far everything goes well. An mutable array (crSelectedMembers) is perfectly set from child view. But... I have trouble setting Membership object. From Paid By controller I use didSelectAtIndexPath to set Membership: [self setCrSelectedMember:[crGroupMembers objectAtIndex:indexPath.row]]; By NSlogging crSelectedMember I get the right selected member in self, but in parent view, to which ivar is pointed, nothing is changed. Am I doing something wrong? Cause I CAN call the method of crSelectedMembers, but I can't change the value of crSelectedMember.
