• Need a Security Scenario for asp.net webservice

  - by Karamafrooz

  I have developed a .Net 3.5 windows forms application. I also want to design a website that has a webservice with multiple Webmethods to query the database on the host machine. I want the webservice to be called ONLY through my winapp and my website! And I don't want any other people to be able to call and use my webservice but only some people who have access to the windows application that I have developed. I need a good security scenario for this! I truly appreciate anyone who can help me because this is my first experience of developing a webservice and I really need it to be as secure as I mentioned!

• Data-related security Implementation

  - by devdude

  Using Shiro we have a great security framework embedded in our enterprise application running on GF. You define users, roles, permissions and we can control at any fine-grain level if a user can access the application, a certain page or even click a specific button. Is there a recipe or pattern, that allows on top of that, to restrict a user from seeing certain data ? Sample: You have a customer table for 3 factories (part of one company). An admin user can see all customer records, but the user at the local factory must not see any customer data of other factories (for whatever reason). Te security feature should be part of the role definition. Thanks for any input and ideas

• How to use @PersistentCapable annotation in Scala 2.8

  - by Gero

  Hi, I'm switching from Scala 2.7.7 to Scala 2.8.0RC3 and now a few of my classes don't compile anymore. The problem is in the @PersistentCapable annotation: import javax.jdo.annotations._ import java.util.Date @PersistenceCapable{identityType=IdentityType.APPLICATION} class Counter(dt: Date, cName: String, vl: int) { <.. snip ..> } This code results in the following compilation errors: [ERROR] /Users/gero/prive/kiva/kivanotify-gae/src/main/scala/net/vermaas/kivanotify/model/LoanProcessed.scala:7: error: expected start of definition [INFO] @PersistenceCapable{val identityType = IdentityType.APPLICATION} I already tried a couple of variations, did some Googling but without luck. Any ideas on how I can use the @PersistentCapable annotation with Scala 2.8.0 RC3? Thanks, Gero

• Any way to rename a deployed ClickOnce app?

  - by tobinibot

  My company has a ClickOnce that has been in use with our customers for about a year now. We're going through a re-branding, and want to change the name of the application. However, just changing all of the normal name options in Visual Studio, and then building a new deploy obviously changes the manifests that the existing app is looking for, so essentially any installed apps never see the new updates. I've tried messing around with the .application file, but haven't been able to get anything to work yet. Is there anyway to rename a deployed ClickOnce app, or do we have to get people to just install the new app?

• Opening a file from a pack URI in WPF

  - by cptmorgan

  Hi All, I am looking to open a .csv file from the application pack to do some unit testing. So what I would really love is some analog to File.ReadAllText(string path) which is instead X.ReadAllText(Uri uri). I haven't as yet been able to find this. Does anyone know if it is possible to read text / bytes (don't mind which) from a file in the pack without compiling this file to disk first? Oh and btw, File.ReadAllText(@"pack://application:,,,/SpreadSheetEngine/Tests/Example.csv") didn't work for me.. Thanks in advance.. Gav

• Error when using SharpDevelop

  - by Sebastian

  I have some code: Outlook.Application outLookApp = new Outlook.Application(); Outlook.Inspector inspector = outLookApp.ActiveInspector(); Outlook.NameSpace nameSpace = outLookApp.GetNamespace("MAPI"); Outlook.MAPIFolder inbox = nameSpace.GetDefaultFolder(Outlook.OlDefaultFolders.olFolderInbox); String sCriteria = "[SenderEmailAddress] = '[email protected]'"; Outlook.Items filteredItems = inbox.Items.Restrict(sCriteria); // totaly sure that count > 0; Outlook.MailItem item = filteredItems[1]; In the last line I have error: "Cannot implicitly convert type 'object' to 'Microsoft.Office.Interop.Outlook.MailItem'. An explicit conversion exists (are you missing a cast?)". I don't know why. Previous I used VisualStudio 2010 but my trial has expired. Is there any hope to run this on SharpDevelop?

• How to avoid manual editing of manifest file

  - by Atara

  My application uses isolated activeX (outer), that depends on another activeX (inner), both are using registration-free-com. The generated manifest file contains only the information for the outer activeX. (probably because vs cannot know that the outer activeX is using inner activeX ) When I re-build my project, I always need to manually add the information for the inner activeX to the manifest file, otherwise the application only shows the outer, without the inner. Is there a way to inform visual studio (2008) that I do not want it to re-generate the manifest file for each build? Will I have such option if I upgrade to VS2010 ? Thanks, Atara

• PHP: How to check if query string or POST vars contain same var twice

  - by thomasrutter

  It may sound strange, but in my PHP application I need to check if the same variable name has been declared more than once in the query string or POST variables, and return an error value if this is the case. If my application doesn't return an error in this case, it fails a compliance check. When accessing vars using $_GET, $_POST, etc, PHP only returns the last value given for each variable name. I can't find a way to tell if any variable appeared more than once. I simply need to find out if the query string or the variables in the POST body contained the same variable name more than once, whatever the values.

• Union on two tables with a where clause in the one

  - by Lostdrifter

  Currently I have 2 tables, both of the tables have the same structure and are going to be used in a web application. the two tables are production and temp. The temp table contains one additional column called [signed up]. Currently I generate a single list using two columns that are found in each table (recno and name). Using these two fields I'm able to support my web application search function. Now what I need to do is support limiting the amount of items that can be used in the search on the second table. the reason for this is become once a person is "signed up" a similar record is created in the production table and will have its own recno. doing: Select recno, name from production UNION ALL Select recno, name from temp ...will show me everyone. I have tried: Select recno, name from production UNION ALL Select recno, name from temp WHERE signup <> 'Y' But this returns nothing? Can anyone help?

• TypeInitilazationException When Getting an NHibernate Session

  - by Paul Johnson

  I’ve run into what appears to be an NHibernate config problem. Basically, I ran up a simple proof of concept persistence integration test using NUnit, the test simply querys an Oracle database and successfully returns the last record received by the underlying table. However, when the assemblies are taken out of the NUnit test environment and deployed as they would be for an actual application build, my call for an NHibernate session results in a ‘TypeInitializationException’ whilst executing the code line: sessionFactory = New Configuration().Configure().BuildSessionFactory() The application is a vb.net console app running against an Oracle 9.2 database, using a ‘coding framework’ published on the web by Bill McCafferty entitled 'NHibernate Best Practices with ASP.NET' (pre S#harp Architecture). I am running version 2.1.2.4000 of NHibernate. Any assistance much appreciated. Kind Regards Paul J.

• Why isn't WH_MOUSE hook global anymore?

  - by Valentin Galea

  I have this global mouse hook setup in a DLL that watches for mouse gestures. Everything works perfectly but with a hook set for WH_MOUSE_LL which is a low-level hook and one that doesn't need to be in an external injectable DLL. Once I switch - to the more suitable one would say - WH_MOUSE mouse hook, everything falls apart. Once I click outside my main application (the one that installs the hook), the hook gets corrupted - ::UnhookWindowsHookEx will fail. I only found this guy saying at experts exchange: "No way, at least under Windows XP + SVP2 WH_MOUSE won't go global, you must use WH_MOUSE_LL instead." I setup the hooks correctly: in a DLL using a shared data section, posting and not sending messages from the hook proceduce. Why has this changed? And why is not documented? Anyone encountered this? Thanks! BTW: I've reverse engineered a bit the popular StrokeIt application and it uses a combination of WH_GETMESSAGE and WH_MOUSE hooks and still works on XP/Vista...

• Java Memory Management

  - by Tara Singh

  I am designing a client-server chat application in Java. This is a secure application where the messages are exchanged using cryptographic algorithms. I have one server and it can support many clients. My problem is that when one client logs on the server it works fine, but when another user logs into the system, the server starts giving me bad padding exceptions for the encrypted text. I am not able to figure out the problem, according to my logic, when new connection request to server is made, the server creates a thread for listening to the client. Is it possible that once the instance of thread class is created, it does all the processing correctly for the first client, but not for the second client because the variables in server listener thread class already have some previous value, and thus the encrypted text is not decrypted properly? Please advise how I can make this process more robust so that the number of clients does not affect how well the server functions.

• Reading from the Registry in ASP.NET

  - by Filip Ekberg

  I have a Library ( DLL ) that has a method with the following: var masterKey = Registry. LocalMachine. OpenSubKey("SOFTWARE\\Microsoft\\Dynamics\\5.0\\"); When running this method in an WinForms applicaiton, masterKey is not null and when running this in asp.net masterKey is null! I've checked the executing user with WindowsIdentity.GetCurrent().Name and the same user is executing both applications. The asp.net application is executed in visual studio ( debug: F5 ) and so is the WinForms application. How come I cannot read the key in asp.net?

• Easy way to apply Joomla template styling to my own content

  - by Joey Adams

  I have an application that is mainly a bunch of PHP files included in a Joomla! application by Jumi. I want to make the site look nicer, but I'd rather not reinvent the wheel. There is a RocketTheme template installed on the site, and I'd like to be able to leverage it or some of the other CSS used alongside it. Specifically, I want to decorate tables. Should I search for and include CSS classes directly into my tags by searching through the template's classes, or is there a framework I could use that automatically adds the right classes based on the current theme?

• Strange behaviour with Microsoft.WindowsCE.Forms

  - by Mohammadreza

  I have a Windows Mobile application in which I want to check the device orientation. Therefore I wrote the following property in one of my forms: internal static Microsoft.WindowsCE.Forms.ScreenOrientation DeviceOriginalOrientation { get; private set; } The strange thing is that after that whenever I open a UserControl, the designer shows this warning even if that UserControl doesn't use the property: Could not load file or assembly 'Microsoft.WindowsCE.Forms, Version=3.5.0.0, Culture=neutral, PublicKeyToken=969db8053d3322ac' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040) Commenting the above property will dismiss the warning and shows the user control again. The application is built successfully and runs without any problems in both cases. Does anybody know why this happens and how can I fix it?

• Facebook Connect Publish to Stream: how do I tag a user?

  - by Sean Cannon

  I have an application that allows martial arts trickers to 'battle' each other by initiating challenges and submitting videos and whatnot. When user A challenges user B, the application posts to the user's wall (the one who initiated the challenge). My question is how do I tag user B in the wall post? It essentially says "challenged John Do to a battle". I'd like "John Do" to link to his profile just like when you manually post something on your wall and use the @ symbol. I hope this makes sense. I've tried standard html for a link, and I've tried FBML. Neither are parsed and only render as plain text on the wall post. Thanks for any help!

• Linux - Create ftp account with read/write access to only 1 folder

  - by Gublooo

  Hey guys.... I have never worked on linux and dont plan on working on it either - The only command I probably know is "ls" :) I am hosting my website on Eapps and use their cpanel to setup everything so never worked with linux. Now I have this one time case - where I need to provide access to a contractor to fix the CSS issues on my website. He basically needs FTP (read/write) access to certain folders. At a high level - this is my code structure /home/webadmin/example.com/html/images /css /js /login.php /facebook.php /home/webadmin/example.com/application/library /views /models /controllers /config /bootstrap.php /home/webadmin/example.com/cgi-bin I want the new user to be able to have access to only these folders /home/webadmin/example.com/html/js /home/webadmin/example.com/html/css /home/webadmin/example.com/application/views He should not be able to view even the content of other folders including files like bootstrap.php or login.php etc If any sys admins can help me set this account up - will really appreciate it. Thanks

• Have you been in cases where TDD increased development time?

  - by BillyONeal

  Hello everyone :) I was reading http://stackoverflow.com/questions/2512504/tdd-how-to-start-really-thinking-tdd and I noticed many of the answers indicate that tests + application should take less time than just writing the application. In my experience, this is not true. My problem though is that some 90% of the code I write has a TON of operating system calls. The time spent to actually mock these up takes much longer than just writing the code in the first place. Sometimes 4 or 5 times as long to write the test as to write the actual code. I'm curious if there are other developers in this kind of a scenario.

• Determine signals connected to a given slot in Qt

  - by Cody Brocious

  I've injected myself into a Qt application, and I'm attempting to figure out what signals a given slot is connected to, but can't find any information on doing this. Is there a mechanism for doing this out of the box? If so, is this exposed to QtScript? (If not, I can wrap it easily enough.) If there is no such mechanism, what would be the best way to add it? I cannot manipulate the existing application outside of simple hooking, but I could hook QObject::connect and store the connections myself, just not sure if that's the best way to go about it.

• Piping SoX in Python - subprocess alternative?

  - by Cochise Ruhulessin

  I use SoX in an application. The application uses it to apply various operations on audiofiles, such as trimming. This works fine: from subprocess import Popen, PIPE kwargs = {'stdin': PIPE, 'stdout': PIPE, 'stderr': PIPE} pipe = Popen(['sox','-t','mp3','-', 'test.mp3','trim','0','15'], **kwargs) output, errors = pipe.communicate(input=open('test.mp3','rb').read()) if errors: raise RuntimeError(errors) This will cause problems on large files hower, since read() loads the complete file to memory; which is slow and may cause the pipes' buffer to overflow. A workaround exists: from subprocess import Popen, PIPE import tempfile import uuid import shutil import os kwargs = {'stdin': PIPE, 'stdout': PIPE, 'stderr': PIPE} tmp = os.path.join(tempfile.gettempdir(), uuid.uuid1().hex + '.mp3') pipe = Popen(['sox','test.mp3', tmp,'trim','0','15'], **kwargs) output, errors = pipe.communicate() if errors: raise RuntimeError(errors) shutil.copy2(tmp, 'test.mp3') os.remove(tmp) So the question stands as follows: Are there any alternatives to this approach, aside from writing a Python extension to the Sox C API?

• GDB hardware watchpoint very slow - why?

  - by Laurynas Biveinis

  On a large C application, I have set a hardware watchpoint on a memory address as follows: (gdb) watch *((int*)0x12F5D58) Hardware watchpoint 3: *((int*)0x12F5D58) As you can see, it's a hardware watchpoint, not software, which would explain the slowness. Now the application running time under debugger has changed from less than ten seconds to one hour and counting. The watchpoint has triggered three times so far, the first time after 15 minutes when the memory page containing the address was made readable by sbrk. Surely during those 15 minutes the watchpoint should have been efficient since the memory page was inaccessible? And that still does not explain, why it's so slow afterwards. The GDB is $ gdb --version GNU gdb (GDB) 7.0-ubuntu [...] Thanks in advance for any ideas as what might be the cause or how to fix/work around it.

• Opening Visual Studio created XAML in Expression Blend

  - by Jens A.

  I have created a console application using Visual Studio 2008. In a few cases, this application shows a WPF dialog. Now, the design view of Visual Studio is a little limited, so I'd like to edit this dialog using Expression Blend 3. Blend does not seem to have an option to load individual XAML files, and when I open my solution in Blend, only the XAML code is displayed when I try to edit the dialog. Edit: I've noticed, that no IntelliSense is available in the text view either. When I create a new WPF Project inside Blend, and copy my dialog there (overwriten MainWindows.xaml), I get a design view. What do I have to do to actually get a design view here? Thank! =) Edit: Header of my XAML file: <Window xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" x:Class="QuantumAnalysis.Deployment.Activation.Checker.MainWindow" x:Name="Window" Title="MainWindow" HorizontalAlignment="Right" Width="600" SizeToContent="Height">

• Dendrogram generated by scipy-cluster does not show

  - by Space_C0wb0y

  I am using scipy-cluster to generate a hierarchical clustering on some data. As a final step of the application, I call the dendrogram function to plot the clustering. I am running on Mac OS X Snow Leopard using the built-in Python 2.6.1 and this matplotlib package. The program runs fine, but at the end the Rocket Ship icon (as I understand, this is the launcher for GUI applications in python) shows up and vanishes immediately without doing anything. Nothing is shown. If I add a 'raw_input' after the call, it just bounces up and down in the dock forever. If I run a simple sample application for matplotlib from the terminal it runs fine. Does anyone have any experiences on this?
