  • How do I dinamically load raw assemblies that contains unmanaged code?(bypassing 'Unverifiable code

    - by Thiado de Arruda
    I'm going to give an example of using System.Data.SQLite.DLL which is a mixed assembly with unmanaged code: If I execute this : var assembly= Assembly.LoadFrom("System.Data.SQLite.DLL") No exceptions are thrown, but if I do this : var rawAssembly = File.ReadAllBytes("System.Data.SQLite.DLL"); var assembly = Assembly.Load(rawAssembly); The CLR throws a FileLoadException with "Unverifiable code failed policy check. (Exception from HRESULT: 0x80131402)". Let's say I'm trying to load this assembly on a child AppDomain, how can I customize the AppDomain's security to allow me pass the policy check?

  • vb.net program cannot connect to wampserver

    - by user225269
    I have a vb.net program that uses mysql as its database. And it works when the computer has wampservr installed. But the program gets an unhandled exception error when the computer where its running does not have a wampserver. The only thing that is installed in it is the mysql connector net. How do I make it work. I just want the two programs to access the same mysql database. I already opened port 20 by configuring firewall. Both in TCP and UDP. What do I do? Do I have to tweak the codes?

What is the best way to get this up and running again? Try and find the appropriate version of the dll or sort out the manifest file? Any pointers much appreciated.

  • Using Google Spreadsheet API on Blackberry

    - by Dev
    I am trying to build a Google spreadsheet synchronization feature on a blackberry application that I am building. Not being a pro I was hunting for some sample code to get a grasp of the flow but I could not. When I am using the API from Google to access spreadsheets, it suggests to use the SpreadsheetService class. try{ SpreadsheetService service = new SpreadsheetService ("MRythm"); service.setUserCredentials("username", "password"); service.getFeed(new URL(""), arg1) }catch(Exception e){ } Now the problem is J2ME or Blackberry does not feature the URL class from java.net library. I am just looking for a sample approach to connect to a Google spreadsheet from Blackberry. Thanks in advance

  • SQL CE unspecified error

    - by Ruben Trancoso
    Hello, I did a project with MS SQL Server CE that when installed in the 'costumer' machine just raises an unspecified excpetion. Did some research and looks like I did everything mentioned. The dev env has sql compact 3.5 installed and sql tools for vs 2005. Using dotNet 3.5.

Its just a single 'unspecified error' message. please help :)

  • Turning an NSImage* into a CGImageRef?

    - by Brian Postow
    Is there an easy way to do this that works in 10.5? In 10.6 I can use nsImage CGImageForProposedRect: NULL context: NULL hints: NULL If I'm not using 1b black and white images (Like Group 4 TIFF), I can use bitmaps, but cgbitmaps seem to not like that setup... Is there a general way of doing this? I need to do this because I have an IKImageView that seems to only want to add CGImages, but all I've got are NSImages. Currently, I'm using a private setImage:(NSImage*) method that I'd REALLY REALLY rather not be using...

  • ASP.NET MVC unit test controller with HttpContext

    - by user299592
    I am trying to write a unit test for my one controller to verify if a view was returned properly, but this controller has a basecontroller that accesses the HttpContext.Current.Session. Everytime I create a new instance of my controller is calls the basecontroller constructor and the test fails with a null pointer exception on the HttpContext.Current.Session. Here is the code: public class BaseController : Controller { protected BaseController() { ViewData["UserID"] = HttpContext.Current.Session["UserID"]; } } public class IndexController : BaseController { public ActionResult Index() { return View("Index.aspx"); } } [TestMethod] public void Retrieve_IndexTest() { // Arrange const string expectedViewName = "Index"; IndexController controller = new IndexController(); // Act var result = controller.Index() as ViewResult; // Assert Assert.IsNotNull(result, "Should have returned a ViewResult"); Assert.AreEqual(expectedViewName, result.ViewName, "View name should have been {0}", expectedViewName); } Any ideas on how to mock the Session that is accessed in the base controller so the test in the descendant controller will run?

  • Django MultiWidget Phone Number Field

    I want to create a field for phone number input that has 2 text fields (size 3, 3, and 4 respectively) with the common "(" ")" "-" delimiters. Below is my code for the field and the widget, I'm getting the following error when trying to iterate the fields in my form during initial rendering (it happens when the for loop gets to my phone number field): Caught an exception while rendering: 'NoneType' object is unsubscriptable class PhoneNumberWidget(forms.MultiWidget): def __init__(self,attrs=None): wigs = (forms.TextInput(attrs={'size':'3','maxlength':'3'}),\ forms.TextInput(attrs={'size':'3','maxlength':'3'}),\ forms.TextInput(attrs={'size':'4','maxlength':'4'})) super(PhoneNumberWidget, self).__init__(wigs, attrs) def decompress(self, value): return value or None def format_output(self, rendered_widgets): return '('+rendered_widgets[0]+')'+rendered_widgets[1]+'-'+rendered_widgets[2] class PhoneNumberField(forms.MultiValueField): widget = PhoneNumberWidget def __init__(self, *args, **kwargs): fields=(forms.CharField(max_length=3), forms.CharField(max_length=3), forms.CharField(max_length=4)) super(PhoneNumberField, self).__init__(fields, *args, **kwargs) def compress(self, data_list): if data_list[0] in fields.EMPTY_VALUES or data_list[1] in fields.EMPTY_VALUES or data_list[2] in fields.EMPTY_VALUES: raise fields.ValidateError(u'Enter valid phone number') return data_list[0]+data_list[1]+data_list[2] class AdvertiserSumbissionForm(ModelForm): business_phone_number = PhoneNumberField(required=True)

  • How can I dispatch an PropertyChanged event from a subscription to an Interval based IObservable

    - by James Hay
    I'm getting an 'UnauthorizedAccesExpection - Invalid cross-thread access' exception when I try to raise a PropertyChanged event from within a subscription to an IObservable collection created through Observable.Interval(). With my limited threading knowledge I'm assuming that the interval is happening on some other thread while the event wants to happen on the UI thread??? An explanation of the problem would be very useful. The code looks a little like: var subscriber = Observable.Interval(TimeSpan.FromSeconds(1)) .Subscribe(x => { Prop = x; // setting property raises a PropertyChanged event }); Any solutions?

  • Websphere MQ 7.0 + jars compatible with 5.3 and 6.0 MQSeries servers ?

    - by avinash
    I tried connecting jms client with 5.3 / 6.0 MQseries client jars to 7.0+ server, but it threw follwoing exception com.ibm.mq.MQException: MQJE001: Completion Code 2, Reason 2423 at com.ibm.mq.MQQueueManager.sequentialConstruct(MQQueueManager.java:904) at com.ibm.mq.MQQueueManager.(MQQueueManager.java:865) at com.ibm.mq.MQSPIQueueManager.(MQSPIQueueManager.java:83) at com.ibm.mq.jms.MQConnection.createQM(MQConnection.java:2009) at com.ibm.mq.jms.MQConnection.createQMNonXA(MQConnection.java:1496) at com.ibm.mq.jms.MQQueueAgentThread.setup(MQQueueAgentThread.java:306) at com.ibm.mq.jms.MQQueueAgentThread.run(MQQueueAgentThread.java:1672) at java.lang.Thread.run(Thread.java:570) I do understand from http://www.ibm.com/developerworks/websphere/library/techarticles/0704_xu/0704_xu.html that it's not possible to use previous version client libs. But my question is are these latest client libs backward compatible with 5.3 / 6.0 servers ?

  • Python: shutil.rmtree fails on Windows with 'Access is denied'

    - by Sridhar Ratnakumar
    In Python, when running shutil.rmtree over a folder that contains a read-only file, the following exception is printed: File "C:\Python26\lib\shutil.py", line 216, in rmtree rmtree(fullname, ignore_errors, onerror) File "C:\Python26\lib\shutil.py", line 216, in rmtree rmtree(fullname, ignore_errors, onerror) File "C:\Python26\lib\shutil.py", line 216, in rmtree rmtree(fullname, ignore_errors, onerror) File "C:\Python26\lib\shutil.py", line 216, in rmtree rmtree(fullname, ignore_errors, onerror) File "C:\Python26\lib\shutil.py", line 216, in rmtree rmtree(fullname, ignore_errors, onerror) File "C:\Python26\lib\shutil.py", line 216, in rmtree rmtree(fullname, ignore_errors, onerror) File "C:\Python26\lib\shutil.py", line 216, in rmtree rmtree(fullname, ignore_errors, onerror) File "C:\Python26\lib\shutil.py", line 221, in rmtree onerror(os.remove, fullname, sys.exc_info()) File "C:\Python26\lib\shutil.py", line 219, in rmtree os.remove(fullname) WindowsError: [Error 5] Access is denied: 'build\\tcl\\tcl8.5\\msgs\\af.msg' Looking in File Properties dialog I noticed that af.msg file is set to be read-only. So the question is: what is the simplest workaround/fix to get around this problem - given that my intention is to do an equivalent of rm -rf build/ but on Windows? (without having to use third-party tools like unxutils or cygwin - as this code is targeted to be run on a bare Windows install with Python 2.6 w/ PyWin32 installed)

  • How to hook Pivotal Tracker to Redmine?

    - by cloneofsnake
    Our company is currently using Redmine, it's great for general tasks / troubleshooting (operation) but for development, I would like to adopt a more agile tool... and I found it in pivotaltracker. I googled but couldn't find any info., so that gave me a good excuse to try StackOverflow. Has anyone done it? I'm thinking of using PivotalTracker as the main tool, and all activities will be posted back to redmine for archiving and reporting. (Redmine isn't particularly strong at that either, but it does have a budget plugin and I can query the database directly for my custom reports.) Thanks.

  • Adding existing entity to navigation property of a different entity

    - by Shay Friedman
    I'm using EF4 and I'm running into a problem when I try to do something that looks quite trivial to me. I have two entities, let's call them A and B. These entities have a many-to-many association between them with a navigation property on A that contains a list of related B entities. What I want to do is to add existing B entities to a new A entity. When I try to do that, I get an exception: AcceptChanges cannot continue because the object's key values conflict with another object in the ObjectStateManager. Make sure that the key values are unique before calling AcceptChanges. Has anyone run into such a problem?

  • External XMPP component - Anyone know a Tutorial or Open Source Example please?

    - by gav
    Hi All, I want to run an XMPP server (Openfire) and register an external component to handle the messages it will recieve (using the Whack library). The external component will run my game logic and I will be using XMPP to send player moves to the server and status updates in the other direction. The bonus with XMPP is that we get built in chat for free. The trouble is, although Ignite look fairly established, I can't find a tutorial on how to write, register and debug an External XMPP component written with Whack, there are very few in general for that matter. I am not invested in either the server implementation or the External Component library, java is just my language of choice. If I was to move to Erlang or Scala or something it would have to be a very simple in that language. A single tutorial or example would go a long way here, I just need an basic External XMPP component pretty please! Kind regards, Gavin

  • What parser generator do you recommend

    - by stefan.ciobaca
    I'm currently shopping for a FOSS parser generator for a project of mine. It has to support either C or C++. I've looked at bison/flex and at boost::spirit. I went from writing my own to spirit to bison to spirit to bison to spirit, each time hit by some feature I found unpleasant. The thing I hate most about bison/flex is that they actually generate C/C++ source for you. There are a number of disadvantages to this, e.g. debugging. I like spirit from this point of view, but I find it very very heavy on syntax. I am curious about what you are using, what you would recommend, and general thoughts about the state of the art in parser generators. I am also curious to hear about approaches being used in other languages for parsing problems.

  • What's your hobby website; do you maintain it for your users or yourself?

    - by Glennular
    What is your hobby website? Do you care if it has high traffic or is it more for personal satisfaction? When deciding on the features to implement are you taking in to consideration the needs of general user-base or features you really want to build? What balance do you use to keep yourself satisfied as well as your users? When do you feel your site is able to release to the world? Do you release it initially and hope for anticipatory beta group? or wait till you have a solid built set of features?

  • Best practices for fixed-width processing in .NET

    - by jmgant
    I'm working a .NET web service that will be processing a text file with a relatively long, multilevel record format. Each record in the file represents a different entity; the record contains multiple sub-types. (The same record format is currently being processed by a COBOL job, if that gives you a better picture of what we're looking at). I've created a class structure (a DATA DIVISION if you will) to hold the input data. My question is, what best practices have you found for processing large, complex fixed-width files in .NET? My general approach will be to read the entire line into a string and then parse the data from the string into the classes I've created. But I'm not sure whether I'll get better results working with the characters in the string as an array, or with the string itself. I guess that's the specific question, string vs. char[], but I would appreciate any other pointers anyone has. Thanks.

  • VS2010 / Code Analysis: Turn off a rule for a project without custom ruleset....

    - by TomTom
    ...any change? The scenario is this: For our company we develop a standard how code should look. This will be the MS full rule set as it looks now. For some specific projects we may want to turn off specific rules. Simply because for a specific project this is a "known exception". Example? CA1026 - while perfectly ok in most cases, there are 1-2 specific libraries we dont want to change those. We also want to avoid having a custom rule set. OTOH putting in a suppress attribute on every occurance gets pretty convoluted pretty fast. Any way to turn off a code analysis warning for a complete assembly without a custom rule set? We rather have that in a specific file (GlobalSuppressions.cs) than in a rule set for maintenance reasons, and to be more explicit ;)

  • What do I return if the return type of a method is Void? (Not void!)

    - by DR
    Due to the use of Generics in Java I ended up in having to implement a function having Void as return type: public Void doSomething() { //... } and the compiler demands that I return something. For now I'm just returning null, but I'm wondering if that is good coding practice... I've also tried Void.class, void, Void.TYPE, new Void(), no return at all, but all that doesn't work at all. (For more or less obvious reasons) (See this answer for details) So what am I supposed to return if the return type of a function is Void? What's the general use of the Void class? EDIT: Just to spare you the downvotes: I'm asking about V?oid, not v?oid. The class Void, not the reserved keyword void.

  • Android: Image displayed at Webview from Url with high quality loss

    - by Merlino
    I want to display an image from an url with an Webview at Android. With Android phones with Version 1.5 and 1.6 there is no problem. but the same pic and the same code on an AndroidPhone with Version 2.0 and the pic is totaly pixelated. Like Android is resizing the image first to a smaller one and then resizing it back to "normal" size. Unfortunately its important to display the pic without any quality loss. I tried to integrate it in the sourcefolder to show it as an normal image, but at Android 2.0 i get an exception because the image is to big. (At Android 1.6 there is no problem) Any ideas how i can display the image without quality loss with Android 2.0 ?

  • noClassDefFoundError using Scala Plugin for Eclipse

  • Ideas for web development practical jokes?

    - by Ellie P.
    I am a web developer for a Django-based site for a student organization, and I have the opportunity to make the website temporarily absurd for a day of general campus-wide debauchery and chaos (long story, doesn't matter.) What are your best ideas for web development practical jokes (that you could never use in the real world)? For example, one idea we had was to use a client-side script to convert each character to its upside down equivalent in Unicode, si?? ??i? ?ui????os. I'm not necessarily looking for Django-specific solutions. I imagine most of these things would happen on the front-end. I am also quite aware that usability will suffer considerably--the point is to be fun for a day, and there will always be a link to the normal version of the site. Also, everything must be relatively cosmetic and easily reversible--I'm happy to swap out static CSS/JS/HTML/templates/images, and even temporarily add a django view, but no messing with the data level!
