  • Copy data from different worksheet to a master worksheet but no duplicates

    - by sam
    hi all, i want to clarify my initial question for a possible solutions from any savior out there. Say i have 3 excel sheets one for each user for data entry located in separate workbooks to avoid excel share workbook problems. I also have a master sheet in another workbook where i want individual data enter on those sheets precisely sheets 1 should copy to the next available row of sheet 1 in the master sheet as the users enter them. i need a vba code that can copy each record without copying a duplicate row in the master sheet but highlight the duplicate row and lookup the initial record in a master sheet and return the name of the Imputer looking up the row say column ( I) where each user sign there initials after every row of entry like below. All 4 worksheets are formatted as below: lastname account cardno. type tran amount date location comments initials JAME 65478923 1975 cash 500 4/10/2010 miles st. this acct is resolve MLK BEN 52436745 1880 CHECK 400 4/12/2010 CAREY ST Ongoing investigation MLK JAME 65478923 1975 cash 500 4/10/2010 miles st. this acct is resolve MLK I need the vba to recognize duplicates only if the account number and the card number matches the initial records. So if the duplicates exist a pop up message should be display that a duplicates exist and return the initial Imputer say MLK in COLUMN( I) to any user inputting in the individual worksheets other than warehouse sheets (master). So please any idea will be appreciated.

  • Is there any way to access files in your source tree in Android?

    - by Chris Thompson
    Hi all, This is a bit unorthodox but I'm trying to figure out if there's a way to access files stored in the src tree of my applications apk in Android. I'm trying to use i-Jetty (Jetty implementation for Android) and rather than use it as a separate application and manually download my war file, I'd rather just bake i-jetty in. However, in order to use (easily) standard html/jsp I need to be able to give it a document root, preferably within my application's apk file. I know Android specifically works to prevent you from accessing (freely) the stuff on the actual system so this may not be possible, but I'm thinking it might be possible to access something within the apk. One option to work around this would be to have all of the files stored in the res directory and then copy them to the sdcard on startup but this wouldn't allow me to automatically remove the files on uninstall. To give you an idea of what I've tried, currently, the html files are stored in org.webtext.android Context rootContext = new Context(server_, "/", Context.SESSIONS); rootContext.setResourceBase("org/webtext/webapp"); Returns a 404 error. final URL url = this.getClassLoader().getResource("org/webtext/webapp"); Context html = new WebAppContext(url.toExternalForm(), "/"); Blows up with a NullPointerException because no URL is returned from the getResource call. Any thoughts would be greatly appreciated! Thanks, Chris

  • iPhone UIView Animation Disables UIButton Subview

    - by bensnider
    So I've got a problem with buttons and animations. Basically, I'm animating a view using the UIView animations while also trying to listen for taps on the button inside the view. The view is just as large as the button, and the view is actually a subclass of UIImageView with an image below the button. The view is a subview of a container view placed in Interface Builder with user interaction enabled and clipping enabled. All the animation and button handling is done in this UIImageView subclass, while the startFloating message is sent from a separate class as needed. If I do no animation, the buttonTapped: message gets sent correctly, but during the animation it does not get sent. I've also tried implementing the touchesEnded method, and the same behavior occurs. UIImageView subclass init (I have the button filled with a color so I can see the frame gets set properly, which it does): - (id)initWithImage:(UIImage *)image { self = [super initWithImage:image]; if (self != nil) { // ...stuffs UIButton *tapBtn = [UIButton buttonWithType:UIButtonTypeCustom]; tapBtn.frame = CGRectMake(0, 0, self.frame.size.width, self.frame.size.height); [tapBtn addTarget:self action:@selector(buttonTapped:) forControlEvents:UIControlEventTouchUpInside]; tapBtn.backgroundColor = [UIColor cyanColor]; [self addSubview:tapBtn]; self.userInteractionEnabled = YES; } return self; } Animation method that starts the animation (if I don't call this the button works correctly): - (void)startFloating { [UIView beginAnimations:@"floating" context:nil]; [UIView setAnimationDelegate:self]; [UIView setAnimationCurve:UIViewAnimationCurveLinear]; [UIView setAnimationDuration:10.0f]; self.frame = CGRectMake(self.frame.origin.x, -self.frame.size.height, self.frame.size.width, self.frame.size.height); [UIView commitAnimations]; } So, to be clear: Using the UIView animation effectively disables the button. Disabling the animation causes the button to work. The button is correctly sized and positioned on screen, and moves along with the view correctly.

  • Combine 3 select fields and validate as one in my User model in ruby on rails 3

    - by Psychonetics
    Ok I have 3 select boxes for selecting date of birth. I have constants setup in my User model to provide months, years etc.. Anyway I can successfully validate these select boxes separately. What I want to do is combine the :day, :month and :year and store in :birthday and validate the whole date as one so I can return 1 error rather than 3 separate ones. Also doing this will make it easier to store the validated date in my birthday field in my database. Part of my form <td> <%= f.input :day, :required => false, :label => "Birthday: " , :prompt => "Day", :collection => User::DAYS %></td> <td> <%= f.input :month, :label => false, :prompt => "Month", :collection => User::MONTHS %> </td> <td> <%= f.input :year, :label => false, :prompt => "Year", :collection => User::YEAR_RANGE %> </td> Part of User model MONTHS = ["January", 1], ["February", 2], ["March", 3], ["April", 4], ["May", 5], ["June", 6], ["July", 7], ["August", 8], ["September", 9], ["October", 10], ["November", 11], ["December", 12] # finish this DAYS = 1..31 # finish this START_YEAR = Time.now.year - 106 END_YEAR = Time.now.year YEAR_RANGE = START_YEAR..END_YEAR class User < ActiveRecord::Base attr_accessor :day, :month, :year validates_presence_of :day, :message = 'What day in a month was you born?' validates_presence_of :month, :message = 'What month was you born?' validates_presence_of :year, :message = 'What is your year of birth?' end

  • JAXB - Beans to XSD or XSD to beans?

    - by bajafresh4life
    I have an existing data model. I would like to express this data model in terms of XML. It looks like I have two options if I'm to use JAXB: Create an XSD that mirrors my data model, and use xjc to create binding objects. Marshalling and unmarshalling will involve creating a "mapping" class that would take my existing data objects and map them to the objects that xjc created. For example, in my data model I have a Doc class, and JAXB would create another Doc class with basically the same exact fields, and I would have to map from my Doc class to xjc's Doc class. Annotate my existing data model with JAXB annotations, and use schemagen to generate an XSD from my annotated classes. I can see advantanges and disadvantages of both approaches. It seems that most people using JAXB start with the XSD file. It makes sense that the XSD should be the gold standard truth, since it expresses the data model in a truly cross-platform way. I'm inclined to start with the XSD first, but it seems icky that I have to write and maintain a separate mapping class that shuttles data in between my world and JAXB world. Any recommendations?

  • Array: mathematical sequence

    - by VaioIsBorn
    An array of integers A[i] (i 1) is defined in the following way: an element A[k] ( k 1) is the smallest number greater than A[k-1] such that the sum of its digits is equal to the sum of the digits of the number 4* A[k-1] . You need to write a program that calculates the N th number in this array based on the given first element A[1] . INPUT: In one line of standard input there are two numbers seperated with a single space: A[1] (1 <= A[1] <= 100) and N (1 <= N <= 10000). OUTPUT: The standard output should only contain a single integer A[N] , the Nth number of the defined sequence. Input: 7 4 Output: 79 Explanation: Elements of the array are as follows: 7, 19, 49, 79... and the 4th element is solution. I tried solving this by coding a separate function that for a given number A[k] calculates the sum of it's digits and finds the smallest number greater than A[k-1] as it says in the problem, but with no success. The first testing failed because of a memory limit, the second testing failed because of a time limit, and now i don't have any possible idea how to solve this. One friend suggested recursion, but i don't know how to set that. Anyone who can help me in any way please write, also suggest some ideas about using recursion/DP for solving this problem. Thanks.

  • Place the business logic in Java Beans?

    - by Lirik
    I was reading this page and I found the following statement: MVC in Java Server Pages Now that we have a convenient architucture to separate the view, how can we leverage that? Java Server Pages (JSP) becomes more interesting because the HTML content can be separated from the Java business objects. JSP can also make use of Java Beans. The business logic could be placed inside Java Beans. If the design is architected correctly, a Web Designer could work with HTML on the JSP site without interfering with the Java developer. Interestingly in my textbook I pulled the following quote: In the MVC architecture... the original request is always handled by a servlet. The servlet invokes the business logic and data access code and creates beans to represent the results (that’s the model). Then, the servlet decides which Java Server Page is appropriate to present those particular results and forwards the request there (the JSP is the view). The servlet decides what business logic code applies and which JSP should present the results (the servlet is the controller). The two statements seem slightly contradicting. What is the best way to use beans: should we place business logic in them or should we only place results in them? Are there ways in which beans are inadequate for representing a model?

  • MS-Access: What could cause one form with a join query to load right and another not?

    - by Daniel Straight
    Form1 Form1 is bound to Table1. Table1 has an ID field. Form2 Form2 is bound to Table2 joined to Table1 on Table2.Table1_ID=Table1.ID Here is the SQL (generated by Access): SELECT Table2.*, Table1.[FirstFieldINeed], Table1.[SecondFieldINeed], Table1.[ThirdFieldINeed] FROM Table1 INNER JOIN Table2 ON Table1.ID = Table2.[Table1_ID]; Form2 is opened with this code in Form1: DoCmd.RunCommand acCmdSaveRecord DoCmd.OpenForm "Form2", , , , acFormAdd, , Me.[ID] DoCmd.Close acForm, "Form1", acSaveYes And when loaded runs: Me.[Table1_ID] = Me.OpenArgs When Form2 is loaded, fields bound to columns from Table1 show up correctly. Form3 Form3 is bound to Table3 joined to Table2 on Table3.Table2_ID=Table2.ID Here is the SQL (generated by Access): SELECT Table3.*, Table2.[FirstFieldINeed], Table2.[SecondFieldINeed] FROM Table2 INNER JOIN Table3 ON Table2.ID = Table3.[Table2_ID]; Form3 is opened with this code in Form2: DoCmd.RunCommand acCmdSaveRecord DoCmd.OpenForm "Form3", , , , acFormAdd, , Me.[ID] DoCmd.Close acForm, "Form2", acSaveYes And when loaded runs: Me.[Table2_ID] = Me.OpenArgs When Form3 is loaded, fields bound to columns from Table2 do not show up correctly. WHY? UPDATES I tried making the join query into a separate query and using that as my record source, but it made no difference at all. If I go to the query for Form3 and view it in datasheet view, I can see that the information that should be pulled into the form is there. It just isn't showing up on the form.

  • Use jquery to create a multidimensional array

    - by Simon M White
    I'd like to use jquery and a multidemensional array to show a random quote plus the name of the individual who wrote it as a separate item. I'll then be able to use css to style them differently. The quote will change upon page refresh. So far i have this code which combines the quote and the name and person who wrote it: $(document).ready(function(){ var myQuotes = new Array(); myQuotes[0] = "Lorem ipsum dolor sit amet, consectetur adipiscing elit. Donec in tortor mauris. Peter Jones, Dragons Den"; myQuotes[1] = "Curabitur interdum, nibh et fringilla facilisis, lacus ipsum pulvinar mauris, eu facilisis justo arcu eget diam. Duis id sagittis elit. Theo Pathetis, Dragons Den"; myQuotes[2] = "Vivamus purus purus, tincidunt et porttitor et, euismod sit amet urna. Etiam sollicitudin eros nec metus pretium scelerisque. James Caan, Dragons Den"; var myRandom = Math.floor(Math.random()*myQuotes.length); $('.quote-holder blockquote span').html(myQuotes[myRandom]); }); any help would be greatly appreciated.

  • Am I under risk of CSRF attacks in a POST form that doesn't require the user to be logged in?

    - by Monika Sulik
    I'm probably being a total noob here, but I'm still uncertain about what a CSRF (Cross-Site Request Forgery) attack is exactly. So lets look at three situations... 1) I have a POST form that I use to edit data on my site. I want this data to be edited only by users that are logged in. 2) I have a site, which can be used by both users who are logged in as well as guests. Parts of the site are for logged in users only, but there are also POST forms that can be used by all users - anonymous and not (for example a standard contact form). Should the contact form be safeguarded against CSRF attacks? 3) I have a site which doesn't have an authentication system at all (well, perhaps that's unrealistic, so lets say it has an admin site which is separate from the rest of it and the admin part is properly safeguarded). The main part of the site is only used by anonymous users. Do the POST forms on it need to be safeguarded? In the case of 1) the answer is clearly yes. But in the case of 2 and 3 I don't know (and is the difference between 2 and 3 even significant?).

  • Unit tests for deep cloning

    - by Will Dean
    Let's say I have a complex .NET class, with lots of arrays and other class object members. I need to be able to generate a deep clone of this object - so I write a Clone() method, and implement it with a simple BinaryFormatter serialize/deserialize - or perhaps I do the deep clone using some other technique which is more error prone and I'd like to make sure is tested. OK, so now (ok, I should have done it first) I'd like write tests which cover the cloning. All the members of the class are private, and my architecture is so good (!) that I haven't needed to write hundreds of public properties or other accessors. The class isn't IComparable or IEquatable, because that's not needed by the application. My unit tests are in a separate assembly to the production code. What approaches do people take to testing that the cloned object is a good copy? Do you write (or rewrite once you discover the need for the clone) all your unit tests for the class so that they can be invoked with either a 'virgin' object or with a clone of it? How would you test if part of the cloning wasn't deep enough - as this is just the kind of problem which can give hideous-to-find bugs later?

  • How can I terminate a system command with alarm in Perl?

    - by rockyurock
    I am running the below code snippet on Windows. The server starts listening continuously after reading from client. I want to terminate this command after a time period. If I use alarm() function call within main.pl, then it terminates the whole Perl program (here main.pl), so I called this system command by placing it in a separate Perl file and calling this Perl file (alarm.pl) in the original Perl File using the system command. But in this way I was unable to take the output of this system() call neither in the original Perl File nor in called one Perl File. Could anybody please let me know the way to terminate a system() call or take the output in that way I used above? main.pl my @output = system("alarm.pl"); print"one iperf completed\n"; open FILE, ">display.txt" or die $!; print FILE @output_1; close FILE; alarm.pl alarm 30; my @output_1 = readpipe("adb shell cd /data/app; ./iperf -u -s -p 5001"); open FILE, ">display.txt" or die $!; print FILE @output_1; close FILE; In both ways display.txt is always empty.

  • Modularity in Flex

    - by Fernando
    I'm working on a pretty big application for Flex/Air. We are using GraniteDS and Tide to interact with the model from our Java EE server. I've been reading about modularization and Modules in Flex. The application has already been built, and I'm figuring a way out to re-design some classes and parts. From what I've read so far, I understand a Module is a different swf which can be dynamically load. Most of the tutorials/documentation are oriented to Flash "programmers" who are using Flex or Air instead of real developers, so that makes online resources harder to get. What I can't understand - yet - is how to encapsulate ActionScript classes or MXML views under this module. I've separated some of the code into libraries. For example, the generated code from Granite is in a "server" library. But I would like to separate parts of the logic with its Moderators, Controllers and Views. Are modules the way to go? Is there a "modules for dummies" or "head first Flex Modules for programmers" like tutorial in order to get a better perspective in order to build my architecture? When to choose libraries and when to choose modules? I'm using Flex 3.5, and a migration to Flex 4 is way far into the future, so no Flex 4 answers please, thanks!

  • Create a delegate from a property getter or setter method

    - by thecoop
    To create a delegate from a method you can use the compile-safe syntax: private int Method() { ... } // and create the delegate to Method... Func<int> d = Method; A property is a wrapper around a getter and setter method, and I want to create a delegate to a property getter method. Something like public int Prop { get; set; } Func<int> d = Prop; // or... Func<int> d = Prop_get; Which doesn't work, unfortunately. I have to create a separate lambda method, which seems unnecessary when the setter method matches the delegate signature anyway: Func<int> d = () => Prop; In order to use the delegate method directly, I have to use nasty reflection, which isn't compile-safe: // something like this, not tested... MethodInfo m = GetType().GetProperty("Prop").GetGetMethod(); Func<int> d = (Func<int>)Delegate.CreateDelegate(typeof(Func<int>), m); Is there any way of creating a delegate on a property getting method directly in a compile-safe way, similar to creating a delegate on a normal method at the top, without needing to use an intermediate lambda method?

  • How do I extract HTML content using Regex in PHP

    - by gAMBOOKa
    I know, i know... regex is not the best way to extract HTML text. But I need to extract article text from a lot of pages, I can store regexes in the database for each website. I'm not sure how XML parsers would work with multiple websites. You'd need a separate function for each website. In any case, I don't know much about regexes, so bear with me. I've got an HTML page in a format similar to this <html> <head>...</head> <body> <div class=nav>...</div><p id="someshit" /> <div class=body>....</div> <div class=footer>...</div> </body> I need to extract the contents of the body class container. I tried this. $pattern = "/<div class=\"body\">\(.*?\)<\/div>/sui" $text = $htmlPageAsIs; if (preg_match($pattern, $text, $matches)) echo "MATCHED!"; else echo "Sorry gambooka, but your text is in another castle."; What am I doing wrong? My text ends up in another castle.

  • Android application transparency and window sizing at root level

    - by ajoburg
    Is it possible to create an application with a transparent background on the root task such that you can see the task running beneath it when it is part of a separate stack? Alternatively, is it possible to run an application so the window of the root task is only a portion of the screen instead of the whole screen? I understand how the transparency and window sizing is done with activities that are not the root task and this works fine. However, the root task of an activity seems to always fill the whole screen and be black even when a transparent theme is applied to the application object in the manifest file. ApplicationManifest.xml: <application android:icon="@drawable/icon" android:label="@string/app_name" android:debuggable="true" android:theme="@style/Theme.Transparent"> Styles.xml <resources> <style name="Theme.Transparent"> <item name="android:windowIsTranslucent">true</item> <item name="android:windowNoTitle">true</item> <item name="android:windowBackground">@drawable/ transparent_background</item> <item name="android:windowAnimationStyle">@android:style/ Animation.Translucent</item> <item name="android:colorForeground">#fff</item> <item name="android:windowIsFloating">true</item> <item name="android:gravity">bottom</item> </style> </resources> Colors.xml <resources> <drawable name="transparent_background">#00000000</drawable> </resources>

  • update variable based upon results from .NET backgroundworker

    - by Bruce
    I've got a C# program that talks to an instrument (spectrum analyzer) over a network. I need to be able to change a large number of parameters in the instrument and read them back into my program. I want to use backgroundworker to do the actual talking to the instrument so that UI performance doesn't suffer. The way this works is - 1) send command to the instrument with new parameter value, 2) read parameter back from the instrument so I can see what actually happened (for example, I try to set the center frequency above the max that the instrument will handle and it tells me what it will actually handle), and 3) update a program variable with the actual value received from the instrument. Because there are quite a few parameters to be updated I'd like to use a generic routine. The part I can't seem to get my brain around is updating the variable in my code with what comes back from the instrument via backgroundworker. If I used a separate RunWorkerCompleted event for each parameter I could hardwire the update directly to the variable. I'd like to come up with a way of using a single routine that's capable of updating any of the variables. All I can come up with is passing a reference number (different for each parameter) and using a switch statement in the RunWorkerCompleted handler to direct the result. There has to be a better way.

  • Reloading a JTree during runtime

    - by Patrick Kiernan
    I create a JTree and model for it out in a class separate to the GUI class. The data for the JTree is extracted from a file. Now in the GUI class the user can add files from the file system to an AWT list. After the user clicks on a file in the list I want the JTree to update. The variable name for the JTree is schemaTree. I have the following code for the when an item in the list is selected: private void schemaListItemStateChanged(java.awt.event.ItemEvent evt) { int selection = schemaList.getSelectedIndex(); File selectedFile = schemas.get(selection); long fileSize = selectedFile.length(); fileInfoLabel.setText("Size: " + fileSize + " bytes"); schemaParser = new XSDParser(selectedFile.getAbsolutePath()); TreeModel model = schemaParser.generateTreeModel(); schemaTree.setModel(model); } I've updated the code to correspond to the accepted answer. The JTree now updates correctly based on which file I select in the list.

  • GAE python database object design for simple list of values

    - by Joey
    I'm really new to database object design so please forgive any weirdness in my question. Basically, I am use Google AppEngine (Python) and contructing an object to track user info. One of these pieces of data is 40 Achievement scores. Do I make a list of ints in the User object for this? Or do I make a separate entity with my user id, the achievement index (0-39) and the score and then do a query to grab these 40 items every time I want to get the user data in total? The latter approach seems more object oriented to me, and certainly better if I extend it to have more than just scores for these 40 achievements. However, considering that I might not extend it, should I even consider just doing a simple list of 40 ints in my user data? I would then forgo doing a query, getting the sorted list of achievements, reading the score from each one just to process a response etc. Is doing this latter approach just such a common practice and hand-waved as not even worth batting an eyelash at in terms of thinking it might be more costly or complex processing wise?

  • Should I be relying on WebTests for data validation?

    - by Alexander Kahoun
    I have a suite of web tests created for a web service. I use it for testing a particular input method that updates a SQL Database. The web service doesn't have a way to retrieve the data, that's not its purpose, only to update it. I have a validator that validates the response XML that the web service generates for each request. All that works fine. It was suggested by a teammate that I add data validation so that I check the database to see the data after the initial response validator runs and compare it with what was in the input request. We have a number of services and libraries that are separate from the web service I'm testing that I can use to get the data and compare it. The problem is that when I run the web test the data validation always fails even when the request succeeds. I've tried putting the thread to sleep between the response validation and the data validation but to no avail; It always gets the data from before the response validation. I can set a break point and visually see that the data has been updated in the DB, funny thing is when I step through it in debug with the breakpoint it does validate successfully. Before I get too much more into this issue I have to ask; Is this the purpose of web tests? Should I be able to validate data through service calls in this manner or am I asking too much of a web test and the response validation is as far as I should go?

  • SQLite assembly not copied to output folder for unit testing

    - by Groo
    Problem: SQLite assembly referenced in my DAL assembly does not get copied to the output folder when doing unit tests (Copy local is set to true). I am working on a .Net 3.5 app in VS2008, with NHibernate & SQLite in my DAL. Data access is exposed through the IRepository interface (repository factory) to other layers, so there is no need to reference NHibernate or the System.Data.SQLite assemblies in other layers. For unit testing, there is a public factory method (also in my DAL) which creates an in-memory SQLite session and creates a new IRepository implementation. This is also done to avoid have a shared SQLite in-memory config for all assemblies which need it, and to avoid referencing those DAL internal assemblies. The problem is when I run unit tests which reside a separate project - if I don't add System.Data.SQLite as a reference to the unit test project, it doesn't get copied to the TestResults...\Out folder (although this project references my DAL project, which references System.Data.SQLite, which has its Copy local property set to true), so the tests fail while NHibernate is being configured. If I add the reference to my testing project, then it does get copied and unit tests work. What am I doing wrong?

  • PayPal: IPN vs PDT

    - by Tom
    Hi, I'm having some trouble choosing between PayPal's Instant Payment Notification (IPN) and Payment Data Transfer (PDT). Basically, users buy a one-off product on my site, pay on PayPal, and return to my site. I understand how IPN works but I'm now seeing that I might be able to trigger the various actions that take place after a successful purchase more easily with PDT, as the data gets returned there and then (as opposed to needing a separate listener). However, PayPal's PDT documentation contains this cryptic line: "PDT is not meant to be used with credit card or Express Checkout transactions." ... but I can't find anything further whatsoever on the topic. (1) Are credit cards REALLY not meant to be used with PDT? I would like more than a sentence. (2) Does that mean that a user must have/create a PayPal account to pay? (3) Does it mean that if I want to allow users to pay with their PayPal accounts AND/OR with credit cards directly, I must implement IPN? Could anyone who's gone through this kindly shed some light? Thank you.

  • LinqToSQL Double Insert issue

    - by Vaccano
    I have a WCF service with an object structure similar to this: public class MyClass { public List<MySubItem> SubItems { get; set; } } public class MySubItem { public List<MySubSubItem> SubSubItems { get; set; } } public class MySubSubItem { public string DataValue { get; set; } } public class MyClassDAL { public void InsertMyClass(MyClass myClass) { ctx.MyClasses.InsertOnSubmit(myClass); ctx.SubmitChanges(); } } Sometimes my client will call in with a MyClass that submits only half of the values that it has in the list SubSubItems. Later it calls the insert with the rest of the list. The problem is that when it does this I get a Primary Key violation. The reason is that it is trying to insert the MySubItem again (because there are more items in the SubSubItems owned by the same MySubItem object). How do I deal with this? Do I just call an Update? Do I have to try to separate them out (updates from inserts)? SQL Server 2008 has a really cool Merge functionally. Is there some way to access that from LinqToSQL?

  • WCF Certificates without Certificate Store

    - by Kane
    My team is developing a number of WPF plug-ins for a 3rd party thick client application. The WPF plug-ins use WCF to consume web services published by a number of TIBCO services. The thick client application maintains a separate central data store and uses a proprietary API to access the data store. The thick client and WPF plug-ins are due to be deployed onto 10,000 workstations. Our customer wants to keep the certificate used by the thick client in the central data store so that they don't need to worry about re-issuing the certificate (current re-issue cycle takes about 3 months) and also have the opportunity to authorise the use of the certificate. The proposed architecture offers a form of shared secret / authentication between the central data store and the TIBCO services. Whilst I don’t necessarily agree with the proposed architecture our team is not able to change it and must work with what’s been provided. Basically our client wants us to build into our WPF plug-ins a mechanism which retrieves the certificate from the central data store (which will be allowed or denied based on roles in that data store) into memory then use the certificate for creating the SSL connection to the TIBCO services. No use of the local machine's certificate store is allowed and the in memory version is to be discarded at the end of each session. So the question is does anyone know if it is possible to pass an in-memory certificate to a WCF (.NET 3.5) service for SSL transport level encryption? Note: I had asked a similar question (here) but have since deleted it and re-asked it with more information.
