  • ASP.NET MVC: dealing with Version field.

    - by alex2k8
    I have a versioned model: public class VersionedModel { public Binary Version { get; set; } } Rendered using <%= Html.Hidden("Version") %> it gives: <input id="Version" name="Version" type="hidden" value="&quot;AQID&quot;" /> that looks a bit strange. Any way, when the form submitted, the Version field is always null. public ActionResult VersionedUpdate(VersionedModel data) { ... } How can I pass Version over the wire? EDIT: A naive solution is: public ActionResult VersionedUpdate(VersionedModel data) { data.Version = GetBinaryValue("Version"); } private Binary GetBinaryValue(string name) { return new Binary(Convert.FromBase64String(this.Request[name].Replace("\"", ""))); }

  • What is a right way to use servlets?

    - by vikp
    Hi, I'm studying EJB3. I have a session bean which provides services to create/update customer accounts. This session bean offers services on the lines of: public void addCustomer(Customer c); public void updateCustomer(Customer c); Ideally I'd like to have a single servlet: CustomerServlet and it would invoke the session beans that I have listed above. Problem is that I have two JSPs: UpdateAccount.jsp and CreateAccount.jsp. Both of these JSPs have a form with a method POST and action "CustomerServlet". How can I distinguish in a customer servlet which operation I should carry out: createAccount or updateAccount? I guess the alternative is to have a separate servlet for each operation... Thank you

  • What explains the term orthogonal in a more non-nerd fashion?

    - by dontWatchMyProfile
    For example: Cardinality and optionality are orthogonal properties of a relationship. You can specify that a relationship is optional, even if you have specified upper and/or lower bounds. This means that there do not have to be any objects at the destination, but if there are then the number of objects must lie within the bounds specified. What exactly does "orthogonal" mean? I bet it's just a fancy soundig nerd-style word for something that could be expressed a lot easier to understand for average people ;) From wikipedia: In mathematics, two vectors are orthogonal if they are perpendicular, i.e., they form a right angle. The word comes from the Greek ????? (orthos), meaning "straight", and ????a (gonia), meaning "angle". Anyone?

  • How do I get Mathematica to thread a 2-variable function over two lists, using functional programmin

    - by Leah Wrenn Berman
    Lets say I have a function f[x_, y_], and two lists l1, l2. I'd like to evaluate f[x,y] where x runs over the list l1 and y runs over the list l2, and I'd like to do it without having to make all pairs of the form {l1[[i]],l2[[j]]}. (Motivation: I'm trying to implement some basic Haskell programs in Mathematica. In particular, I'd like to be able to code the Haskell program isMatroid::[[Int]]->Bool isMatroid b =and[or[sort(union(xs\\[x])[y]'elem'b|y<-ys]|xs<-b,ys<-b, xs<-x] I think I can do the rest of it, if I can figure out the original question, but I'd like the code to be Haskell-like. Any suggestions for implementing Haskell-like code in Mathematica would be appreciated.)

  • Non-graphical linearity estimation

    - by aL3xa
    In my previous post, I was looking for correlation ratio (η or η2) routines in R. I was surprised by the fact that no one uses η for linearity checking in the GLM procedures. Let's start form a simple example: how do you check linearity of bivariate correlation? Solely with scatterplot? There are several ways of doing this, one way is to compare linear and non-linear model R2, then to apply F test to seek for significant difference between them. Finally, the question is: How do you check linearity, the "non-grafical" way?

  • Return tiff file from outputstream on JSP

    - by YYY
    I am using a JSP to display a single TIFF file. The flow is as follows: I am given a PDF to convert to a TIFF. I feed a 'black box' API the PDF in the form of a File object and an OutputStream (I am currently using a ByteArrayOutputStream but that can change as needed. The 'black box' converts the PDF to a TIFF and saves the result to the OutputStream. I use out.println(outputstream) to spit out the TIFF. The problem is that I am getting a text stream instead of a displayed image. I have used the following head/meta tag: <head><title>PDF to TIFF tester</title> <META HTTP-EQUIV="Content-Script-Type" CONTENT="image/tiff"></head> <body> But that does not change the end result. Any help?

  • How to save bytes to an image and access it from Bottle

    - by Graham Smith
    I'm working on an API wrapper for Snapchat using Python and Bottle, but in order to return the file (retrieved by the Python script) I have to save the bytes (returned by Snapchat) to a .jpg file. I'm not quite sure how I will do this and still be able to access the file so that it can be returned. Here's what I have so far, but it returns a 404. @route('/image') def image(): username = request.query.username token = request.query.auth_token img_id = request.query.id return get_blob(username, token, img_id) def get_blob(usr, token, img_id): # Form URL and download encrypted "blob" blob_url = "https://feelinsonice.appspot.com/ph/blob?id={}".format(img_id) blob_url += "&username=" + usr + "&timestamp=" + str(timestamp()) + "&req_token=" + req_token(token) enc_blob = requests.get(blob_url).content # Save decrypted image FileUpload.save('/images/' + img_id + '.jpg') img = open('images/' + img_id + '.jpg', 'wb') img.write(decrypt(enc_blob)) img.close() return static_file(img_id + '.jpg', root='/images/')

  • Using C# Type as generic

    - by I Clark
    I'm trying to create a generic list from a specific Type that is retrieved from elsewhere: Type listType; // Passed in to function, could be anything var list = _service.GetAll<listType>(); However I get a build error of: The type or namespace name 'listType' could not be found (are you missing a using directive or an assembly reference?) Is this even possible or am I setting foot onto C# 4 Dynamic territory? As a background: I want to automatically load all lists with data from the repository. The code below get's passed a Form Model whose properties are iterated for any IEnum (where T inherits from DomainEntity). I want to fill the list with objects of the Type the list made of from the repository. public void LoadLists(object model) { foreach (var property in model.GetType() .GetProperties(BindingFlags.Public | BindingFlags.Instance | BindingFlags.SetProperty)) { if (IsEnumerableOfNssEntities(property.PropertyType)) { var listType = property.PropertyType.GetGenericArguments()[0]; var list = _repository.Query<listType>().ToList(); property.SetValue(model, list, null); } } }

  • Avoiding string copying in Lua

    - by Matt Sheppard
    Say I have a C program which wants to call a very simple Lua function with two strings (let's say two comma separated lists, returning true if the lists intersect at all, false if not). The obvious way to do this is to push them onto the stack with lua_pushstring, which works fine, however, from the doc it looks like lua_pushstring but makes a copy of the string for Lua to work with. That means that to cross over to the Lua function is going to require two string copies which I could avoid by rewriting the Lua function in C. Is there any way to arrange things so that the existing C strings could be reused on the Lua side for the sake of performance (or would the strcpy cost pale into insignificance anyway)? From my investigation so far (my first couple of hours looking seriously at Lua), lite userdata seems like the sort of thing I want, but in the form of a string.

  • Adobe Livecycle Designer 7 Text Field Issue

    - by MachinationX
    I have a form in a large box, to be filled in by the user with up to 2500 characters. Currently, the cursor starts in the vertical center of the box and I would like: a) The cursor to start at the top left of the field instead of the middle left, so that there is no whitespace above the user's entered text. or b) Somehow enabling a field that expands to fit its text to expand as the text is being entered. As far as I can tell, text fields set to expand to fit the text inside only expand once the user has taken their cursor off the field. Thanks for your help!

  • JavaScript: What is AJAX? What is jQuery?

    What exactly IS AJAX? Is there an official release? What exactly is jQuery? Is there an official release? From what I understand, these two "extensions" of JavaScript are just small scripts that enable extended functionality. But, what exactly are there? I mean, Adobe is a company that created Flash. If you want information about Flash, the official source is at Adobe. Is there an equivalent for AJAX and jQuery? I don't want to learn AJAX or jQuery form some shmo that doesn't know that correct syntax. I want to learn proper syntax and best practices.

  • Programming issue while applying text to the third party control.

    - by srivatsa
    Hello I have used some third party controls in my windows application. There is a snippet which is being used in our code which re-initializes all the .text property of all the controls on the form. Everything works fine except for a control. This control is similar to the Windows Panel except for it has a dropdown appearance. This control has .Caption property instead of .Text property associated to it. This causes the problem whenever i use such codes foreach (Control oControl in this.Controls) { if (oControl is DropDownPanel) { { oControl.Text = rm_ResourceManager.GetString(oControl.Name + ".Text"); } } } The text is not set here for the DropDownPanel control in the above method. Since .Text is not available for DropDownPanel control. I cannot do the following either .. ((DropDownPanel)oControl).Caption = rm_ResourceManager.GetString(oControl.Name + ".Text"); Cos it shall throw exception if i try to cast oControl with that of DropDownPanel Any ideas how can i overcome such a condition. Regards

  • JavaScript To Strip Page For URL

    - by Russell C.
    We have a javascript function we use to track page stats internally. However, the URLs it reports many times include the page numbers for search results pages which we would rather not be reported. The pages that are reports are of the form: http://www.test.com/directory1/2 http://www.test.com/directory1/subdirectory1/15 http://www.test.com/directory3/1113 Instead we'd like the above reported as: http://www.test.com/directory1 http://www.test.com/directory1/subdirectory1 http://www.test.com/directory3 Please note that the numbered 'directory' and 'subdirectory' names above are just for example purposes and that the actual subdirectory names are all different, don't necessarily include numbers at the end of the directory name, and can be many levels deep. Currently our JavaScript function produces these URLs using the code: var page = location.hostname+document.location.pathname; I believe we need to use the JavaScript replace function in combination with some regex but I'm at a complete loss as to what that would look like. Any help would be much appreciated! Thanks in advance!

  • Perform manual test, automate after - or never?

    - by dotnetdev
    In my current company, we have one tester. Having spoken to this tester, she says that in testing, before implementing any automation systems, the scripts (steps to take) are manually written and performed (performed at least once). Is this the way things work in testing? To make me laugh, this has been done in this case, yet no automation. It makes me laugh to see the lead tester perform loads of different combinations of usernames and passwords for a login form (which she is not overly keen on having automated) when I could easily automate that (but politics in the company won't allow that). This doesn't seem like the environment where a junior tester (not me, I'm a SDET) cannot learn anything. Thanks

    Hi Everyone, I have a kase model which I am using a simple search form in. The problem I am having is some kases are linked to companies through a company model, and people through a people model. At the moment my search (in Kase model) looks like this: # SEARCH FACILITY def self.search(search) search_condition = "%" + search + "%" find(:all, :conditions => ['jobno LIKE ? OR casesubject LIKE ? OR transport LIKE ? OR goods LIKE ? OR comments LIKE ? OR invoicenumber LIKE ? OR netamount LIKE ? OR clientref LIKE ? OR kase_status LIKE ? OR lyingatlocationaddresscity LIKE ?', search_condition, search_condition, search_condition, search_condition, search_condition, search_condition, search_condition, search_condition, search_condition, search_condition]) end What I am trying to work out, is what condition can I add to allow a search by Company or Person to show the cases they are linked to. @kase.company.companyname and company.companyname don't work :( Is this possible?

  • basic unique ModelForm field for Google App Engine

    - by Alexander Vasiljev
    I do not care about concurrency issues. It is relatively easy to build unique form field: from django import forms class UniqueUserEmailField(forms.CharField): def clean(self, value): self.check_uniqueness(super(UniqueUserEmailField, self).clean(value)) def check_uniqueness(self, value): same_user = users.User.all().filter('email', value).get() if same_user: raise forms.ValidationError('%s already_registered' % value) so one could add users on-the-fly. Editing existing user is tricky. This field would not allow to save user having other user email. At the same time it would not allow to save a user with the same email. What code do you use to put a field with uniqueness check into ModelForm?

  • Why is generated XAML spitting out namespaces that are not asked for?

    - by Matt Holmes
    I have a very simple XAML form, that has one namespace definition. For some reason, when Visual Studio processes that XAML file in to it's component .g.cs, it's sticking a bunch of namespace definitions at the top that I have not asked for in the XAML, or the code behind, and they are namespaces that no longer exist in my project. Thus the project is failing to compile. Why is Visual Studio sticking arbitrary namespace 'using' statements in my generated XAML .g.cs files? It's caused my entire project to break. Not one time did this .xaml file ever reference the namespaces in question, so it's doubly annoying.

  • css anchor div to foot of page

    - by foxed
    I may bounce my head off the wall shortly, I can't believe that something as stupid as this has utterly defeated me ... therefore I turn to you, Stack Overflow ... for guidance and enlightenment. Problem: Sit div at foot of page, 100% width, outside of any sort of wrapper. Proposed Solution: http://ryanfait.com/sticky-footer/ Implementation with content: http://www.weleasewodewick.com/redesign/index_content.html Implementation with no content: http://www.weleasewodewick.com/redesign/index.html with content - Good, works nicely no content = bad, footer sits exactly height of footer below the viewport. I really would appreciate your input into this, it's completely vexed me for the past hour. I wholly expect some form of ridicule :) Thanks! Foxed
