  • SSIS 2005 Error while using script component Designer: "Cannot fetch a row from OLE DB provider "BUL

    - by user150541
    I am trying to debug a dts package in SSIS. I have a script component designer where I pass in the input variables to increment a counter. When I try to msgbox the counter value, I get the following error. Error: 0xC0202009 at STAGING1 to STAGING2, STAGING2 Destination [1056]: An OLE DB error has occurred. Error code: 0x80040E14.

  • Grouping consecutive identical items: IEnumerable<T> to IEnumerable<IEnumerable<T>>

    - by Romain Verdier
    I've got an interresting problem: Given an IEnumerable<string>, is it possible to yield a sequence of IEnumerable<string> that groups identical adjacent strings in one pass? Let me explain. Considering the following IEnumerable<string> (pseudo representation): {"a","b","b","b","c","c","d"} How to get an IEnumerable<IEnumerable<string>> that would yield something of the form: { // IEnumerable<IEnumerable<string>> {"a"}, // IEnumerable<string> {"a","b","b"}, // IEnumerable<string> {"c","c"}, // IEnumerable<string> {"d"} // IEnumerable<string> } The method prototype would be: public IEnumerable<IEnumerable<string>> Group(IEnumerable<string> items) { // todo } Important notes : Only one iteration over the original sequence No intermediary collections allocations (we can assume millions of strings in the original sequence, and millions consecutives identicals strings in each group) Keeping enumerators and defered execution behavior Is it possible, and how would you write it?

  • Asp.Net MVC Tutorial Unit Tests

    - by Nicholas
    I am working through Steve Sanderson's book Pro ASP.NET MVC Framework and I having some issues with two unit tests which produce errors. In the example below it tests the CheckOut ViewResult: [AcceptVerbs(HttpVerbs.Post)] public ViewResult CheckOut(Cart cart, FormCollection form) { // Empty carts can't be checked out if (cart.Lines.Count == 0) { ModelState.AddModelError("Cart", "Sorry, your cart is empty!"); return View(); } // Invoke model binding manually if (TryUpdateModel(cart.ShippingDetails, form.ToValueProvider())) { orderSubmitter.SubmitOrder(cart); cart.Clear(); return View("Completed"); } else // Something was invalid return View(); } with the following unit test [Test] public void Submitting_Empty_Shipping_Details_Displays_Default_View_With_Error() { // Arrange CartController controller = new CartController(null, null); Cart cart = new Cart(); cart.AddItem(new Product(), 1); // Act var result = controller.CheckOut(cart, new FormCollection { { "Name", "" } }); // Assert Assert.IsEmpty(result.ViewName); Assert.IsFalse(result.ViewData.ModelState.IsValid); } I have resolved any issues surrounding 'TryUpdateModel' by upgrading to ASP.NET MVC 2 (Release Candidate 2) and the website runs as expected. The associated error messages are: *Tests.CartControllerTests.Submitting_Empty_Shipping_Details_Displays_Default_View_With_Error: System.ArgumentNullException : Value cannot be null. Parameter name: controllerContext* and the more detailed at System.Web.Mvc.ModelValidator..ctor(ModelMetadata metadata, ControllerContext controllerContext) at System.Web.Mvc.DefaultModelBinder.OnModelUpdated(ControllerContext controllerContext, ModelBindingContext bindingContext) at System.Web.Mvc.DefaultModelBinder.BindComplexModel(ControllerContext controllerContext, ModelBindingContext bindingContext) at System.Web.Mvc.Controller.TryUpdateModel[TModel](TModel model, String prefix, String[] includeProperties, String[] excludeProperties, IValueProvider valueProvider) at System.Web.Mvc.Controller.TryUpdateModel[TModel](TModel model, IValueProvider valueProvider) at WebUI.Controllers.CartController.CheckOut(Cart cart, FormCollection form) Has anyone run into a similar issue or indeed got the test to pass?

  • Crystal reports 11 RDC (COM API) displays printer dialog even when I tell it not to prompt

    - by bdonlan
    I'm using Crystal Reports 11's RDC (COM) API to print. My code looks like this: HRESULT res = m_Report->SelectPrinter(b_driver, b_device, b_port); if (FAILED(res)) return res; // For these calls, the #import wrapper throws on error m_Report->PutPrinterDuplex(dmDuplex); m_Report->PutPaperSize(dmPaperSize); m_Report->PutPaperSource((CRPaperSource)pdlg->GetDevMode()->dmDefaultSource); if (m_Report->GetPaperOrientation() == crDefaultPaperOrientation) m_Report->PutPaperOrientation(crPortrait); VARIANT vfalse; VariantInit(&vfalse); vfalse.vt=VT_BOOL; vfalse.boolVal=0; res = m_Report->PrintOut(vfalse); However, at the end of all this, crystal reports still shows its own printer selection dialog - but only for some reports, it seems. Why does crystal reports show a print dialog even when I pass false for promptUser? And how, then, can I suppress crystal reports' internal printer selection dialog and force it to use my values? Edit: Whoops, CR11, not CR9. Some further information: The reports that work properly (ie, do not show the print dialog) are generated internally using the RDC API; we create a new report object, import subreports into it, then print the result. No problem there. The reports that do not work properly (ie, force the print dialog to open) have been created with a previous version of crystal reports; however, opening and saving the report does not seem to help. Sample reports in the Crystal Reports installation directory show the same problem. I tried reproducing with VBScript; however, the result was that nothing was printed at all (no dialog, no nothing): Set app = CreateObject("CrystalRuntime.Application.11") Set report = app.OpenReport("C:\Program Files\Business Objects\Crystal Reports 11.5\Samples\en\Reports\General Business\Inventory Crosstab.rpt") report.PrintOut(True) rem Testing with a True parameter to force a print dialog - but no printout and nothing appears (no error either though)

  • How to print PDF on default network printer using GhostScript (gswin32c.exe) shell command

    - by Maciej
    I'd like to print PDF file(s) on windows' network printer via GhostScript. (I dont want to use Adobe Reader) I've read gswin32c.exe which can do the job. I experimented with many commands and coudn't find the way how to force gs to print PDF on my (windows default) network drive. I don't need point exact network printer- default can be used. But if there is no such option I'm happy to pass printer name as well. (I've tried with param -SDevice="\server_IP\printer_name" but this didnt work as well...) Command working under Windows cmd: gswin32c -dPrinted -dBATCH -dNOPAUSE -dNOSAFER -q -dNumCopies=1 -sDEVICE=ljet4 -sOutputFile="\\spool\\\Server_Name\Printer_name" "C:\test.pdf" Method created base on above - doesnt work and thorws exception. (Error code = 1) /// <summary> /// Prints the PDF. /// </summary> /// <param name="ghostScriptPath">The ghost script path. Eg "C:\Program Files\gs\gs8.71\bin\gswin32c.exe"</param> /// <param name="numberOfCopies">The number of copies.</param> /// <param name="printerName">Name of the printer.

  • Authenticating to Google Search Appliance using Basic HTTP auth and ASP.NET (VB)

    - by Chainlink
    I've run into a snag though which has to do with authentication between the Google Search Appliance and ASP. Normally, when asking for secure pages from the search appliance, the search appliance asks for credentials, then uses these credentials to try and access the secure results. If this attempt is successful, the page shows up in the results list. Since ASP is contacting the search appliance on the client's behalf, it will need to collect credentials and pass them along to the search appliance. I have tried a couple of different documented ways of accomplishing this, but they don't seem to work. Below is the code I have tried: 'Bypass SSL since discovery.gov.mb.ca does not have valid SSL cert (NOT PRODUCTION SAFE) ServerCertificateValidationCallback = New System.Net.Security.RemoteCertificateValidationCallback(AddressOf customXertificateValidation) googleUrl = "https://removed.com" Dim rdr As New XmlTextReader(googleUrl) Dim resolver As New XmlUrlResolver() Dim myCred As New System.Net.NetworkCredential("USERNAME", "PASSWORD", Nothing) Dim credCache As New CredentialCache() credCache.Add(New Uri(googleUrl), "Basic", myCred) resolver.Credentials = credCache rdr.XmlResolver = resolver doc = New System.Xml.XPath.XPathDocument(rdr) path = doc.CreateNavigator() Private Function customXertificateValidation(ByVal sender As Object, ByVal certificate As System.Security.Cryptography.X509Certificates.X509Certificate, ByVal chain As System.Security.Cryptography.X509Certificates.X509Chain, ByVal sslPolicyErrors As Net.Security.SslPolicyErrors) As Boolean Return True End Function

  • Django users and authentication from external source

    - by Boldewyn
    I have a Django app that gets it's data completely from an external source (queried via HTTP). That is, I don't have the option for a local database. Session data is stored in the cache (on my development server I use a SQLite database, so that is no error source). I'm using bleeding edge Django 1.1svn. Enter the problem: I want to use Django's own authentication system for the users. It seems quite simple to write my own Authentication Backend, but always just under the condition that you have a local database where to save the users. Without database my main problem is persistence. I tried it with the following (assume that datasource.get() is a function that returns some kind of dict): class ModelBackend (object): """Login backend.""" def authenticate (self, username=None, password=None): """Check, if a given user/password combination is valid""" data = datasource.get ('login', username, password) if data and data['ok']: return MyUser (username=username) else: raise TypeError return None def get_user (self, username): """get data about a specific user""" try: data = datasource.get ('userdata', username) if data and data['ok']: return data.user except: pass return None class MyUser (User): """Django user who isn't saved in DB""" def save (self): return None But the intentionally missing save() method on MyUser seems to break the session storage of a login. How should MyUser look like without a local database?

  • Integrating a Custom Compiler with the Visual Studio IDE

    - by M.A. Hanin
    Background: I want to create a custom VB compiler, extending the "original" compiler, to handle my custom compile-time attributes. Question: after I've created my custom compiler and I've got an executable file capable of compiling VB code via the standard command-line interface, how do I integrate this compiler with the Visual Studio IDE? (such that pressing "compile" or "build" will make use of my compiler instead of the default compiler). EDIT: (Correct me if i'm wrong) From the reactions here, I see this question is a bit shocking, so I shall further explain my needs and background: .NET provides us with a great mechanism called Attributes. As far as I understand, making attributes apply their intended behavior upon the attributed element (assembly, module, class, method, etc.) - attributes must be reflected upon. So the real trick here is reflecting and applying behavior at the right spot. Lets take Serialization for example: We decorate a class with the Serializable attribute. We then pass an instance of the class to the formatter's Serialize method. The formatter reflects upon the instance, checking if it has the Serializable attribute, and acting accordingly. Now, if we examine the Synchronization, Flags, Obsolete and CLSCompliant attributes, then the real question is: who reflects upon them? At least in some cases, it has to be the compiler (and/or IDE). Therefore, it seems that if I wish to create custom attributes that change an element's behavior regardless of any specific consumer, i must extend the compiler to reflect upon them at compilation. Of course, these are not my personal insights: the book "Applied .NET Attributes" provides a complete example of creating a custom attribute and a custom C# compiler to reflect upon that attribute at compilation (the example is used to implement "java-style checked exceptions").

  • Does jQuery strip some html elements from a string when using .html()?

    - by Nic Hubbard
    I have a var that contains a full html page, including the head, html, body, etc. When I pass that string into the .html() function, jQuery strips out all those elements, such as body, html, head, etc, which I don't want. My data var contains: <html> <head> <title>Untitled Document</title> </head> <body> </body> </html> // data is a full html document string data = $('<div/>').html(data); // jQuery stips my document string! alert(data.find('head').html()); I am needing to manipulate a full html page string, so that I can return what is in the element. I would like to do this with jQuery, but it seems all of the methods, append(), prepend() and html() all try to convert the string to dom elements, which remove all the other parts of a full html page. Is there another way that I could do this? I would be fine using another method. My final goal is to find certain elements inside my string, so I figured jQuery would be best, since I am so used to it. But, if it is going to trim and remove parts of my string, I am going to have to look for another method. Ideas?

  • Difference between GL10 and GLES10 on Android

    - by kayahr
    The GLSurfaceView.Renderer interface of the Android SDK gives me a GL interface as parameter which has the type GL10. This interface is implemented by some private internal jni wrapper class. But there is also the class GLES10 where all the GL methods are available as static methods. Is there an important difference between them? So what if I ignore the gl parameter of onDrawFrame and instead use the static methods of GLES10 everywhere? Here is an example. Instead of doing this: void onDrawFrame(GL10 gl) { drawSomething(gl); } void drawSomething(GL10 gl) { gl.glLoadIdentity(); ... } I could do this: void onDrawFrame(GL10 gl) { drawSomething(); } void drawSomething() { GLES10.glLoadIdentity(); ... } The advantage is that I don't have to pass the GL context to all called methods. But even it it works (And it works, I tried it) I wonder if there are any disadvantages and reasons to NOT do it like that.

  • Chunked responses in libevent2

    - by Sri
    Hi I am trying to do a chunked response (of large files) in libevent this way:: evhttp_send_reply_start(request, HTTP_OK, "OK"); int fd = open("filename", O_RDONLY); size_t fileSize = <get_file_size>; struct evbuffer *databuff = NULL; for (off_t offset = 0;offset < fileSize;) { databuff = evbuffer_new(); size_t bytesLeft = fileSize - offset; size_t bytesToRead = bytesLeft > MAX_READ_SIZE ? MAX_READ_SIZE : bytesLeft; evbuffer_add_file(databuff, fd, offset, bytesToRead); offset += bytesToRead; evhttp_send_reply_chunk(request, databuff); // send it evbuffer_free(databuff); // destroy it } evhttp_send_reply_end(request); fclose(fptr); Problem is with this I have a feeling the add_file is asynchronous so the 3rd or so evhttp_send_reply_chunk gives me an error (or something similar): [warn] evhttp_send_chain Closed(45): Bad file descriptor I set MAX_READ_SIZE to be 8 to actually test out chunked transfer encoding. I noticed there was a evhttp_request_set_chunked_cb (struct evhttp_request *, void(*cb)(struct evhttp_request *, void *)) method I could use but could not find any examples on how to use. For instance, how could I pass an argument to the callback? The argument seems to be the same argument that was passed to the request handler which is not what I want, because I want to create an object that holds the file descriptor and the file offset I am sending out. Appreciate all help. Thanks in advance Sri

  • Django Class Views and Reverse Urls

    - by kalhartt
    I have a good many class based views that use reverse(name, args) to find urls and pass this to templates. However, the problem is class based views must be instantiated before urlpatterns can be defined. This means the class is instantiated while urlpatterns is empty leading to reverse throwing errors. I've been working around this by passing lambda: reverse(name, args) to my templates but surely there is a better solution. As a simple example the following fails with exception: ImproperlyConfigured at xxxx The included urlconf mysite.urls doesn't have any patterns in it mysite.urls from mysite.views import MyClassView urlpatterns = patterns('', url(r'^$' MyClassView.as_view(), name='home') ) views.py class MyClassView(View): def get(self, request): home_url = reverse('home') return render_to_response('home.html', {'home_url':home_url}, context_instance=RequestContext(request)) home.html <p><a href={{ home_url }}>Home</a></p> I'm currently working around the problem by forcing reverse to run on template rendering by changing views.py to class MyClassView(View): def get(self, request): home_url = lambda: reverse('home') return render_to_response('home.html', {'home_url':home_url}, context_instance=RequestContext(request)) and it works, but this is really ugly and surely there is a better way. So is there a way to use reverse in class based views but avoid the cyclic dependency of urlpatterns requiring view requiring reverse requiring urlpatterns...

  • javascript function won't stop looping - It's on a netsuite website

    - by Lauren
    I need to change the shipping carrier drop-down and shipping method radio button once via a javascript function, not forever. However, when I use this function, which executes when on the Review and Submit page when the order is < $5, it goes into an endless loop: function setFreeSampShipping(){ var options = document.forms['checkout'].shippingcarrierselect.getElementsByTagName('option'); for (i=0;i<options.length;i++){ if (options[i].value == 'nonups'){ document.forms['checkout'].shippingcarrierselect.value='nonups'; document.forms['checkout'].shippingcarrierselect.onchange(); document.location.href='/app/site/backend/setshipmeth.nl?c=659197&n=1&sc=4&sShipMeth=2035'; } } } It gets called from within this part of the function setSampPolicyElems() which you can see I've commented out to stop the loop: if (carTotl < 5 && hasSampp == 1) { /* if (document.forms['checkout'].shippingcarrierselect.value =='ups'){ setFreeSampShipping(); } */ document.getElementById('sampAdd').style.display="none"; document.getElementById("custbody_ava_webshiptype").value = "7";//no charge free freight if (document.getElementById("applycoupon")) { document.location.href='/app/site/backend/setpromocode.nl?c=659197&n=1&sc=4&kReferralCode=SAMPLE' } document.write("<div id='msg'><strong>Sample & Shipping:</strong></span> No Charge.

  • 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.

  • Python sorting list of dictionaries by multiple keys

    - by simi
    I have a list of dicts: b = [{u'TOT_PTS_Misc': u'Utley, Alex', u'Total_Points': 96.0}, {u'TOT_PTS_Misc': u'Russo, Brandon', u'Total_Points': 96.0}, {u'TOT_PTS_Misc': u'Chappell, Justin', u'Total_Points': 96.0}, {u'TOT_PTS_Misc': u'Foster, Toney', u'Total_Points': 80.0}, {u'TOT_PTS_Misc': u'Lawson, Roman', u'Total_Points': 80.0}, {u'TOT_PTS_Misc': u'Lempke, Sam', u'Total_Points': 80.0}, {u'TOT_PTS_Misc': u'Gnezda, Alex', u'Total_Points': 78.0}, {u'TOT_PTS_Misc': u'Kirks, Damien', u'Total_Points': 78.0}, {u'TOT_PTS_Misc': u'Worden, Tom', u'Total_Points': 78.0}, {u'TOT_PTS_Misc': u'Korecz, Mike', u'Total_Points': 78.0}, {u'TOT_PTS_Misc': u'Swartz, Brian', u'Total_Points': 66.0}, {u'TOT_PTS_Misc': u'Burgess, Randy', u'Total_Points': 66.0}, {u'TOT_PTS_Misc': u'Smugala, Ryan', u'Total_Points': 66.0}, {u'TOT_PTS_Misc': u'Harmon, Gary', u'Total_Points': 66.0}, {u'TOT_PTS_Misc': u'Blasinsky, Scott', u'Total_Points': 60.0}, {u'TOT_PTS_Misc': u'Carter III, Laymon', u'Total_Points': 60.0}, {u'TOT_PTS_Misc': u'Coleman, Johnathan', u'Total_Points': 60.0}, {u'TOT_PTS_Misc': u'Venditti, Nick', u'Total_Points': 60.0}, {u'TOT_PTS_Misc': u'Blackwell, Devon', u'Total_Points': 60.0}, {u'TOT_PTS_Misc': u'Kovach, Alex', u'Total_Points': 60.0}, {u'TOT_PTS_Misc': u'Bolden, Antonio', u'Total_Points': 60.0}, {u'TOT_PTS_Misc': u'Smith, Ryan', u'Total_Points': 60.0}] and I need to use a multi key sort reversed by Total_Points, then not reversed by TOT_PTS_Misc. This can be done at the command prompt like so: a = sorted(b, key=lambda d: (-d['Total_Points'], d['TOT_PTS_Misc'])) But I have to run this through a function, where I pass in the list and the sort keys. For example, def multikeysort(dict_list, sortkeys):. How can the lambda line be used which will sort the list, for an arbitrary number of keys that are passed in to the multikeysort function, and take into consideration that the sortkeys may have any number of keys and those that need reversed sorts will be identified with a '-' before it?

  • How to do custom display and auto-select in django admin multi-select field?

    - by rsp
    I'm new to django, so please feel free to tell me if I'm doing this incorrectly. I am trying to create a django ordering system. My order model: class Order(models.Model): ordered_by = models.ForeignKey(User, limit_choices_to = {'groups__name': "Managers", 'is_active': 1}) in my admin ANY user can enter an order, but ordered_by must be someone in the group "managers" (this is the behavior I want). Now, if the logged in user happens to be a manager I want it to automatically fill in the field with that logged in user. I have accomplished this by: class OrderAdmin(admin.ModelAdmin): def formfield_for_foreignkey(self, db_field, request, **kwargs): if db_field.name == "ordered_by": if request.user in User.objects.filter(groups__name='Managers', is_active=1): kwargs["initial"] = request.user.id kwargs["empty_label"] = "-------------" return db_field.formfield(**kwargs) return super(OrderAdmin, self).formfield_for_foreignkey(db_field, request, **kwargs) This also works, but the admin puts the username as the display for the select box by default. It would be nice to have the user's real name listed. I was able to do it with this: class UserModelMultipleChoiceField(forms.ModelMultipleChoiceField): def label_from_instance(self, obj): return obj.first_name + " " + obj.last_name class OrderForm(forms.ModelForm): ordered_by = UserModelChoiceField(queryset=User.objects.all().filter(groups__name='Managers', is_active=1)) class OrderAdmin(admin.ModelAdmin): form = OrderForm My problem: I can't to both of these. If I put in the formfield_for_foreignkey function and add form = OrderForm to use my custom "UserModelChoiceField", it puts the nice name display but it won't select the currently logged in user. I'm new to this, but my guess is that when I use UserModelChoiceField it "erases" the info passed in via formfield_for_foreignkey. Do I need to use the super() function somehow to pass on this info? or something completely different?

  • Grails - Simple hasMany Problem - How does 'save' work?

    - by gav
    My problem is this: I want to create a grails domain instance, defining the 'Many' instances of another domain that it has. I have the actual source in a Google Code Project but the following should illustrate the problem. class Person { String name static hasMany[skills:Skill] static constraints = { id (visible:false) skills (nullable:false, blank:false) } } class Skill { String name String description static constraints = { id (visible:false) name (nullable:false, blank:false) description (nullable:false, blank:false) } } If you use this model and def scaffold for the two Controllers then you end up with a form like this that doesn't work; My own attempt to get this to work enumerates the Skills as checkboxes and looks like this; But when I save the Volunteer the skills are null! This is the code for my save method; def save = { log.info "Saving: " + params.toString() def skills = params.skills log.info "Skills: " + skills def volunteerInstance = new Volunteer(params) log.info volunteerInstance if (volunteerInstance.save(flush: true)) { flash.message = "${message(code: 'default.created.message', args: [message(code: 'volunteer.label', default: 'Volunteer'), volunteerInstance.id])}" redirect(action: "show", id: volunteerInstance.id) log.info volunteerInstance } else { render(view: "create", model: [volunteerInstance: volunteerInstance]) } } This is my log output (I have custom toString() methods); 2010-05-10 21:06:41,494 [http-8080-3] INFO bumbumtrain.VolunteerController - Saving: ["skills":["1", "2"], "name":"Ian", "_skills":["", ""], "create":"Create", "action":"save", "controller":"volunteer"] 2010-05-10 21:06:41,495 [http-8080-3] INFO bumbumtrain.VolunteerController - Skills: [1, 2] 2010-05-10 21:06:41,508 [http-8080-3] INFO bumbumtrain.VolunteerController - Volunteer[ id: null | Name: Ian | Skills [Skill[ id: 1 | Name: Carpenter ] , Skill[ id: 2 | Name: Sound Engineer ] ]] Note that in the final log line the right Skills have been picked up and are part of the object instance. When the volunteer is saved the 'Skills' are ignored and not commited to the database despite the in memory version created clearly does have the items. Is it not possible to pass the Skills at construction time? There must be a way round this? I need a single form to allow a person to register but I want to normalise the data so that I can add more skills at a later time. If you think this should 'just work' then a link to a working example would be great. Hope this makes sense, thanks in advance! Gav

  • Passing char * into fopen with C.

    Hey there, I'm writing a program that passes data from a file into an array, but I'm having trouble with fopen (). It seems to work fine when I hardcode the file path into the parameters (eg fopen ("data/1.dat", "r");) but when I pass it as a pointer, it returns NULL. Note that line 142 will print "data/1.dat" if entered from command line so parse_args () appears to be working. 132 int 133 main(int argc, char **argv) 134 { 135 FILE *in_file; 136 int *nextItem = (int *) malloc (sizeof (int)); 137 set_t *dictionary; 138 139 /* Parse Arguments */ 140 clo_t *iopts = parse_args(argc, argv); 141 142 printf ("INPUT FILE: %s.\n", iopts->input_file); /* This prints correct path */ 143 /* Initialise dictionary */ 144 dictionary = set_create (SET_INITAL_SIZE); 145 146 /* Use fscanf to read all data values into new set_t */ 147 if ((in_file = fopen (iopts->input_file, "r")) == NULL) 148 { 149 printf ("File not found...\n"); 150 return 0; 151 } Thanks!

  • How do I securely authenticate the calling assembly of a WCF service method?

    - by Tim
    The current situation is as follows: We have an production .net 3.5 WCF service, used by several applications throughout the organization, over wsHttpBinding or netTcpBinding. User authentication is being done on the Transport level, using Windows integrated security. This service has a method Foo(string parameter), which can only be called by members of given AD groups. The string parameter is obligatory. A new client application has come into play (.net 3.5, C# console app), which eliminates the necessity of the string parameter. However, only calls from this particular application should be allowed to omit the string parameter. The identity of the caller of the client application should still be known by the server because the AD group limitation still applies (ruling out impersonation on the client side). I found a way to pass on the "evidence" of the calling (strong-named) assembly in the message headers, but this method is clearly not secure because the "evidence" can easily be spoofed. Also, CAS (code access security) seems like a possible solution, but I can't seem to figure out how to make use of CAS in this particular scenario. Does anyone have a suggestion on how to solve this issue? Edit: I found another thread on this subject; apparently the conclusion there is that it is simply impossible to implement in a secure fashion.

  • Why doesn't every class in the .Net framework have a corresponding interface?

    - by Thorsten Lorenz
    Since I started to develop in a test/behavior driven style, I appreciated the ability to mock out every dependency. Since mocking frameworks like Moq work best when told to mock an interface, I now implement an interface for almost every class I create b/c most likely I will have to mock it out in a test eventually. Well, and programming to an interface is good practice, anyways. At times, my classes take dependencies on .Net classes (e.g. FileSystemWatcher, DispatcherTimer). It would be great in that case to have an interface, so I could depend on an IDispatcherTimer instead, to be able to pass it a mock and simulate its behavior to see if my system under test reacts correctly. Unfortunately both of above mentioned classes do not implement such interfaces, so I have to resort to creating adapters, that do nothing else but inherit from the original class and conform to an interface, that I then can use. Here is such an adapter for the DispatcherTimer and the corresponding interface: using System; using System.Windows.Threading; public interface IDispatcherTimer { #region Events event EventHandler Tick; #endregion #region Properties Dispatcher Dispatcher { get; } TimeSpan Interval { get; set; } bool IsEnabled { get; set; } object Tag { get; set; } #endregion #region Public Methods void Start(); void Stop(); #endregion } /// <summary> /// Adapts the DispatcherTimer class to implement the <see cref="IDispatcherTimer"/> interface. /// </summary> public class DispatcherTimerAdapter : DispatcherTimer, IDispatcherTimer { } Although this is not the end of the world, I wonder, why the .Net developers didn't take the minute to make their classes implement these interfaces from the get go. It puzzles me especially since now there is a big push for good practices from inside Microsoft. Does anyone have any (maybe inside) information why this contradiction exists?

  • IIS 7.5 What am I doing wrong?

    - by chugh97
    In IIS 7.5 under Windows 7 Utilmate, I have an application which is configured for authentication as follows: Anonymous & Windows In the ASP.NET Website, I have turned Forms authentication and identity impersonate = true I also deny any anonymous users. <authentication mode="Forms"> </authentication> <identity impersonate="true"/> <authorization> <deny user="?"> </authorization> IIS complains. What am I doing wrong... What I want to achieve :I want the windows Logged On User so I can build a FormsAuthentication ticket and pass it to a Passive STS. So in IIS I have anonymous and windows...If have only windows ticked, I cannot go onto the Login.aspx page as I have an extra parameter to be passed from there. So now in webconfig, I then disable anonymous users by saying deny user="?" , so it leaves me with the authenticated windows user but using Forms Authentication.You know what I mean??

  • Extra fulltext ordering criteria beyond default relevance

    - by Jeremy Warne
    I'm implementing an ingredient text search, for adding ingredients to a recipe. I've currently got a full text index on the ingredient name, which is stored in a single text field, like so: "Sauce, tomato, lite, Heinz" I've found that because there are a lot of ingredients with very similar names in the database, simply sorting by relevance doesn't work that well a lot of the time. So, I've found myself sorting by a bunch of my own rules of thumb, which probably duplicates a lot of the full-text search algorithm which spits out a numerical relevance. For instance (abridged): ORDER BY [ingredient name is exactly search term], [ingredient name starts with search term], [ingredient name starts with any word from the search and contains all search terms in some order], [ingredient name contains all search terms in some order], ...and so on. Each of these is defined in the SELECT specification as an expression returning either 1 or 0, and so I order by those in sequential order. I would love to hear suggestions for: A better way to define complicated order-by criteria in one place, say perhaps in a view or stored procedure that you can pass just the search term to and get back a set of results without having to worry about how they're ordered? A better tool for this than MySQL's fulltext engine -- perhaps if I was using Sphinx or something [which I've heard of but not used before], would I find some sort of complicated config option designed to solve problems like this? Some google search terms which might turn up discussion on how to order text items within a specific domain like this? I haven't found much that's of use. Thanks for reading!

  • VB.Net Custom Object Master-Detail Data Binding

    - by clawson
    Since beginning to use VB.Net some years ago I have become slowly familiar with using the data binding features of .Net, however I often find my self bewildered by it's behavior and instead of discover the correct way it should work I find some dirty work around to suit my needs and continue on. Needless to say my problems continue to arise. I am using Custom Objects as the Data Sources for by controls and often entire forms. I find it frustrating to separate business logic and the graphical interface. (That could be a new question entirely.) So for a lot of objects I generate a form which has the DataBindingSource for the object. When I create each from using the New Constructor I explicitly pass to it the object to which it should be bound, and then set this passed object as the DataSource of the BindingSource. (That's a mouthful!) Now the Master object (say, bound to each form) often contains a List of objects which I like to have displayed in a DataGridView. I (sometimes) create and modify these child objects in their own form (again creating a databind the same way as the master form) but when I add them to the List in the master object the DataGridView won't update with the new items. So my question really has a few layers: How can I easily/efficiently/correctly update this DataGridView with the list of Detail objects when I add them to the list of the Master object. Is this approach to DataBinding good/viable. What's the best way to separate business logic from graphical interface. Thanks for the help!

  • Multiple Jira instances on a single Tomcat 6 server?

    - by davidhayes
    I have a feeling this is a stupid question but I can't find the answer anywhere... I need to deploy 2 Jira instances on asingle Tomcat server, I can't figure out how to pass in the jira.home property The documentation says I need to:- Add a web context property called 'jira.home' — this property is set in different files depending on your application server. For example, for Tomcat (and therefore for JIRA Standalone), you will need to configure the server.xml file. For other application servers you may need to configure the web.xml file, or set 'Context parameter' options on the deployment UI of the application server, etc. Note that If you have specified a JIRA home in jira-application.properties (ie. the recommended method), it will override your web context property. I was hoping something like this would work. <Context jira.home="d:/jira/data" path="" docBase="D:\Jira\atlassian-jira-enterprise-4.1\dist-tomcat\tomcat-6\atlassian-jira-4.1.war" debug="0"> <Resource name="jdbc/JiraDS" auth="Container" type="javax.sql.DataSource" username="sa" password="*****" driverClassName="net.sourceforge.jtds.jdbc.Driver" url="jdbc:jtds:sqlserver://*****:1433/jira41_519;user=****;password=****" /> <Resource name="UserTransaction" auth="Container" type="javax.transaction.UserTransaction" factory="org.objectweb.jotm.UserTransactionFactory" jotm.timeout="60"/> <Manager pathname=""/> </Context> Any ideas??

  • Adding an observer to UIImageView? observer & notifications

    - by sagar
    Each class has almost one method named addObserver [imgVURL addObserver:<#(NSObject *)observer#> forKeyPath:<#(NSString *)keyPath#> options:<#(NSKeyValueObservingOptions)options#> context:<#(void *)context#>] Here, imgVURL is an image which is going to be load an image asynchronously. When image will be loaded dynamically - other class will set an image from loaded data. Now, my question is how can we add an observer to UIImageView's instance. Observer and notifications are same or not ? If it is not then what's different ? Let's have some sample code That I did in my project to understand my question. // locating image view from Scroll view by it's tag imgVURL=(UIImageView*)[scrMain viewWithTag:(kTagImagesTag+i)]; // ImageViewURL is a class which contains methods of // didReceiveResponse // didReceiveData // connection ImageViewURL *tmp=[[ImageViewURL alloc] init]; // it has a nonatomic property which will take the reference of my image view tmp.imgV=imgVURL; // now I will pass a url from my an array to property strURL // in strUrl I have custom setter // in which I am initializing a connection tmp.strUrl=[NSURL URLWithString:[[tblmain objectAtIndex:i] valueForKey:@"url"]]; // from ImageViewURL.m file -(void)connectionDidFinishLoading:(NSURLConnection *)connection { [[UIApplication sharedApplication] setNetworkActivityIndicatorVisible:NO]; // NSLog@"ImageView Ref From - %@",imgV); // see imgV has reference of my -> imgVURL (nonatomic,assign) imgV.image=[UIImage imageWithData:myWebData]; [connection release]; connection=nil; } // as you can see in above code many many images are loaded asynchronously // now How can I add an observer to an imageview whether it received or not.
