  • unwanted space before and after nested html table using Internet Explorer 8

    - by John
    I have an html table nested in an html table cell. I want the nested table to use the full size of the cell it is nested in. When I use firefox or google chrome I get the result I want but when I use Internet Explorer 8 (even if I use td style="height="100%") the height of the nested cell depends on it's content. As a result I get whitespace before and after my nested table.

  • How can I provide an ASP.NET Forms Authentication UX while using Active Directory Role and Authentic

    - by Nate Bross
    Is it possible to use this Role Provider AspNetWindowsTokenRoleProvider with ASP.NET FORMS Authentication (via this MembershipProvider System.Web.Security.ActiveDirectoryMembershipProvider)? It seems to only work with <authentication mode="Windows">, is it possible to use it with FORMS? background -- The objective here is to provide an ASP.NET Forms UX while using Active Directory as the back-end authentication system. If there is another, easy way to do this using built-in technologies, that's great and I'd like to hear about that as well.

  • C#: Windows Forms: Getting keystrokes in a panel/picturebox?

    - by Rosarch
    I'm making a level editor for a game using windows forms. The form has several drop down menus, text boxes, etc, where the user can type information. I want to make commands like CTRL + V or CTRL + A available for working within the game world itself, not text manipulation. The game world is represented by a PictureBox contained in a Panel. This event handler isn't ever firing: private System.Windows.Forms.Panel canvas; // ... this.canvas = new System.Windows.Forms.Panel(); // ... this.canvas.PreviewKeyDown += new System.Windows.Forms.PreviewKeyDownEventHandler(this.canvas_PreviewKeyDown); What is the preferred way of doing this? Can a panel even receive keyboard input? I would like to allow the user to use copy/paste/select-all commands when working with the text input, but not when placing objects in the game world.

  • How can I display multiple django modelformset forms in a grouped fieldsets?

    - by JT
    I have a problem with needing to provide multiple model backed forms on the same page. I understand how to do this with single forms, i.e. just create both the forms call them something different then use the appropriate names in the template. Now how exactly do you expand that solution to work with modelformsets? The wrinkle, of course, is that each 'form' must be rendered together in the appropriate fieldset. For example I want my template to produce something like this: <fieldset> <label for="id_base-0-desc">Home Base Description:</label> <input id="id_base-0-desc" type="text" name="base-0-desc" maxlength="100" /> <label for="id_likes-0-icecream">Want ice cream?</label> <input type="checkbox" name="likes-0-icecream" id="id_likes-0-icecream" /> </fieldset> <fieldset> <label for="id_base-1-desc">Home Base Description:</label> <input id="id_base-1-desc" type="text" name="base-1-desc" maxlength="100" /> <label for="id_likes-1-icecream">Want ice cream?</label> <input type="checkbox" name="likes-1-icecream" id="id_likes-1-icecream" /> </fieldset> I am using a loop like this to process the results (after form validation) base_models = base_formset.save(commit=False) like_models = like_formset.save(commit=False) for base_model, likes_model in map(None, base_models, likes_models): which works as I'd expect (I'm using map because the # of forms can be different). The problem is that I can't figure out a way to do the same thing with the templating engine. The system does work if I layout all the base models together then all the likes models after wards, but it doesn't meet the layout requirements. EDIT: Updated the problem statement to be more clear about what exactly I'm processing (I'm processing models not forms in the for loop)

  • C#: Windows Forms: What could cause Invalidate() to not redraw?

    - by Rosarch
    I'm using Windows Forms. For a long time, pictureBox.Invalidate(); worked to make the screen be redrawn. However, it now doesn't work and I'm not sure why. this.worldBox = new System.Windows.Forms.PictureBox(); this.worldBox.BackColor = System.Drawing.SystemColors.Control; this.worldBox.BorderStyle = System.Windows.Forms.BorderStyle.FixedSingle; this.worldBox.Location = new System.Drawing.Point(170, 82); this.worldBox.Name = "worldBox"; this.worldBox.Size = new System.Drawing.Size(261, 250); this.worldBox.TabIndex = 0; this.worldBox.TabStop = false; this.worldBox.MouseMove += new System.Windows.Forms.MouseEventHandler(this.worldBox_MouseMove); this.worldBox.MouseDown += new System.Windows.Forms.MouseEventHandler(this.worldBox_MouseDown); this.worldBox.MouseUp += new System.Windows.Forms.MouseEventHandler(this.worldBox_MouseUp); Called in my code to draw the world appropriately: view.DrawWorldBox(worldBox, canvas, gameEngine.GameObjectManager.Controllers, selectedGameObjects, LevelEditorUtils.PREVIEWS); View.DrawWorldBox: public void DrawWorldBox(PictureBox worldBox, Panel canvas, ICollection<IGameObjectController> controllers, ICollection<IGameObjectController> selectedGameObjects, IDictionary<string, Image> previews) { int left = Math.Abs(worldBox.Location.X); int top = Math.Abs(worldBox.Location.Y); Rectangle screenRect = new Rectangle(left, top, canvas.Width, canvas.Height); IDictionary<float, ICollection<IGameObjectController>> layers = LevelEditorUtils.LayersOfControllers(controllers); IOrderedEnumerable<KeyValuePair<float, ICollection<IGameObjectController>>> sortedLayers = from item in layers orderby item.Key descending select item; using (Graphics g = Graphics.FromImage(worldBox.Image)) { foreach (KeyValuePair<float, ICollection<IGameObjectController>> kv in sortedLayers) { foreach (IGameObjectController controller in kv.Value) { // ... float scale = controller.View.Scale; float width = controller.View.Width; float height = controller.View.Height; Rectangle controllerRect = new Rectangle((int)controller.Model.Position.X, (int)controller.Model.Position.Y, (int)(width * scale), (int)(height * scale)); // cull objects that aren't intersecting with the canvas if (controllerRect.IntersectsWith(screenRect)) { Image img = previews[controller.Model.HumanReadableName]; g.DrawImage(img, controllerRect); } if (selectedGameObjects.Contains(controller)) { selectionRectangles.Add(controllerRect); } } } foreach (Rectangle rect in selectionRectangles) { g.DrawRectangle(drawingPen, rect); } selectionRectangles.Clear(); } worldBox.Invalidate(); } What could I be doing wrong here?

  • Forms authentication: how do you store username password in web.config?

    - by Nick G
    I'm used to using Forms Authentication with a database, but I'm writing a little internal utility and the app doesn't have a database so I want to store the username and password in web.config. However for some reason, forms authentication is still trying to access SQL Server and I can't see how to stop it doing this and pick up the credentials from web.config. What am I doing wrong? I just get the error "Failed to generate a user instance of SQL Server due to a failure in impersonating the client. The connection will be closed." Here are the relevant sections of my web.config: <configuration> <system.web> <authentication mode="Forms"> <forms loginUrl="~/Login.aspx" timeout="60" name=".LoginCookie" path="/" > <credentials passwordFormat="Clear"> <user name="user1" password="[pass]" /> <user name="user2" password="[pass]" /> </credentials> </forms> </authentication> <authorization> <deny users="?" /> </authorization> </system.web> </configuration>

  • Can regular expressions be used to match nested patterns?

    - by Richard Dorman
    Is it possible to write a regular expression that matches a nested pattern that occurs an unknown number of times. For example, can a regular expression match an opening and closing brace when there are an unknown number of open closing braces nested within the outer braces. For example: public MyMethod() { if (test) { // More { } } // More { } } // End Should match: { if (test) { // More { } } // More { } }

  • Creating and Using a jQuery Plug-in in ASP.NET Web Forms

    - by bipinjoshi
    Developers often resort to code reuse techniques in their projects. As far as ASP.NET framework server side programming is concerned classes, class libraries, components, custom server controls and user controls are popular code reuse techniques. Modern ASP.NET web applications no longer restrict themselves only to server side programming. They also make use of client side scripting to render rich web forms. No wonder that Microsoft Visual Studio 2010 includes jQuery library by default as a part of newly created web site. If you are using jQuery for client side scripting then one way to reuse your client side code is to create a jQuery plug-in. Creating a plug-in allows you to bundle your reusable jQuery code in a neat way and then reuse it across web forms. In this article you will learn how to create a simple jQuery plug-in from scratch. You will also learn about certain guidelines that help you build professional jQuery plug-ins.http://www.bipinjoshi.net/articles/aae84a03-b4a8-477d-b087-5b7f42935220.aspx

  • .aspx websites: Is it built using web forms?

    - by Lazeera
    I visit many website which I think is built using ASP.NET web forms because of the extension (.aspx). When I view source of these website I see at least one or two something like: <input type="hidden" name="__VIEWSTATE" id="__VIEWSTATE"> or wvcD4NCjxwPtin2YTZh9iv2YrYqSDYp9mE2KvYp9mG2YrYqSDZh9mKINit2..... However, yesterday I visited two sites on is the 'ASP.NET forums - http://forums.asp.net' and the other is 'POF'. The extension of these sites is still (.aspx) but when I view the source of these site I could not find any <input type="hidden" name="__VIEWSTATE" id="__VIEWSTATE"> nor wvcD4NCjxwPtin2YTZh9iv2YrYqSDYp9mE2KvYp9mG2YrYqSDZh9mKINit2..... Now, I would like to know how those sites use ASP.NET Web Forms and their final HTML output is still clean?

  • Mixing Forms and Token Authentication in a single ASP.NET Application (the Details)

    - by Your DisplayName here!
    The scenario described in my last post works because of the design around HTTP modules in ASP.NET. Authentication related modules (like Forms authentication and WIF WS-Fed/Sessions) typically subscribe to three events in the pipeline – AuthenticateRequest/PostAuthenticateRequest for pre-processing and EndRequest for post-processing (like making redirects to a login page). In the pre-processing stage it is the modules’ job to determine the identity of the client based on incoming HTTP details (like a header, cookie, form post) and set HttpContext.User and Thread.CurrentPrincipal. The actual page (in the ExecuteHandler event) “sees” the identity that the last module has set. So in our case there are three modules in effect: FormsAuthenticationModule (AuthenticateRequest, EndRequest) WSFederationAuthenticationModule (AuthenticateRequest, PostAuthenticateRequest, EndRequest) SessionAuthenticationModule (AuthenticateRequest, PostAuthenticateRequest) So let’s have a look at the different scenario we have when mixing Forms auth and WS-Federation. Anoymous request to unprotected resource This is the easiest case. Since there is no WIF session cookie or a FormsAuth cookie, these modules do nothing. The WSFed module creates an anonymous ClaimsPrincipal and calls the registered ClaimsAuthenticationManager (if any) to transform it. The result (by default an anonymous ClaimsPrincipal) gets set. Anonymous request to FormsAuth protected resource This is the scenario where an anonymous user tries to access a FormsAuth protected resource for the first time. The principal is anonymous and before the page gets rendered, the Authorize attribute kicks in. The attribute determines that the user needs authentication and therefor sets a 401 status code and ends the request. Now execution jumps to the EndRequest event, where the FormsAuth module takes over. The module then converts the 401 to a redirect (302) to the forms login page. If authentication is successful, the login page sets the FormsAuth cookie.   FormsAuth authenticated request to a FormsAuth protected resource Now a FormsAuth cookie is present, which gets validated by the FormsAuth module. This cookie gets turned into a GenericPrincipal/FormsIdentity combination. The WS-Fed module turns the principal into a ClaimsPrincipal and calls the registered ClaimsAuthenticationManager. The outcome of that gets set on the context. Anonymous request to STS protected resource This time the anonymous user tries to access an STS protected resource (a controller decorated with the RequireTokenAuthentication attribute). The attribute determines that the user needs STS authentication by checking the authentication type on the current principal. If this is not Federation, the redirect to the STS will be made. After successful authentication at the STS, the STS posts the token back to the application (using WS-Federation syntax). Postback from STS authentication After the postback, the WS-Fed module finds the token response and validates the contained token. If successful, the token gets transformed by the ClaimsAuthenticationManager, and the outcome is a) stored in a session cookie, and b) set on the context. STS authenticated request to an STS protected resource This time the WIF Session authentication module kicks in because it can find the previously issued session cookie. The module re-hydrates the ClaimsPrincipal from the cookie and sets it.     FormsAuth and STS authenticated request to a protected resource This is kind of an odd case – e.g. the user first authenticated using Forms and after that using the STS. This time the FormsAuth module does its work, and then afterwards the session module stomps over the context with the session principal. In other words, the STS identity wins.   What about roles? A common way to set roles in ASP.NET is to use the role manager feature. There is a corresponding HTTP module for that (RoleManagerModule) that handles PostAuthenticateRequest. Does this collide with the above combinations? No it doesn’t! When the WS-Fed module turns existing principals into a ClaimsPrincipal (like it did with the FormsIdentity), it also checks for RolePrincipal (which is the principal type created by role manager), and turns the roles in role claims. Nice! But as you can see in the last scenario above, this might result in unnecessary work, so I would rather recommend consolidating all role work (and other claims transformations) into the ClaimsAuthenticationManager. In there you can check for the authentication type of the incoming principal and act accordingly. HTH

  • How to render a POST and make it show up on another page

    - by stack5914
    I'm trying to create a marketplace website similar to craigslist. I created a form according to the Django tutorial "Working with forms", but I don't know how to render information I got from the POST forms. I want to make information(subject,price...etc) that I got from POST show up on another page like this. http://bakersfield.craigslist.org/atq/3375938126.html and, I want the "Subject"(please look at form.py) of this product(eg.1960 French Chair) to show up on another page like this. http://bakersfield.craigslist.org/ata/ } Can I get some advice to handle submitted information? Here's present codes. I'll appreciate all your answers and helps. <-! Here's my codes -- ?forms.py from django import forms class SellForm(forms.Form): subject = forms.CharField(max_length=100) price = forms.CharField(max_length=100) condition = forms.CharField(max_length=100) email = forms.EmailField() body = forms.TextField() ?views.py from django.shortcuts import render, render_to_response from django.http import HttpResponseRedirect from site1.forms import SellForm def sell(request): if request.method =="POST": form =SellForm(request.POST) if form.is_valid(): subject = form.cleaned_data['subject'] price = form.cleaned_data['price'] condition = form.cleaned_data['condition'] email = form.cleaned_data['email'] body = form.cleaned_data['body'] return HttpResponseRedirect('/books/') else: form=SellForm() render(request, 'sell.html',{'form':form,}) ?urls.py from django.conf.urls import patterns, include, url from django.contrib import admin admin.autodiscover() urlpatterns = patterns('', url(r'^sechand/$','site1.views.sell'), url(r'^admin/', include(admin.site.urls)), ) ?sell.html <form action = "/sell/" method = "post">{% csrf_token%} {{ form.as_p }} <input type = "submit" value="Submit" /> </form>

  • How to number nested ordered lists.

    - by Wes
    Is there any way through CSS to style nested ordered lists to display sub numbers? The idea is similar to using heading levels. However what I'd really like to see is the following. Note each of these subsections has text not just a title. This isn't a real example just some organisational stuff. Now I know I can use <h1>-<h6> but nested lists would be much clearer and allow for different indentation styling. Also it would be symentically correct. Note I don't think that <h1>-<h6> are correct in many ways as the name doesn't apply to the whole section. 1 Introduction. 1.1 Scope Blah Blah Blah Blah Blah Blah 1.2 Purpose Blah Blah Blah Blah Blah Blah 2 Cars Blah Blah Blah Blah Blah Blah 2.1 engines sub Blah Blah Blah sub Blah Blah Blah 2.2 Wheels ... ... 2.10.21 hub caps sub-sub Blah Blah Blah sub-sub Blah Blah Blah 2.10.21.1 hub cap paint sub-sub-sub Blah Blah Blah sub-sub-sub Blah Blah Blah 3 Planes 3.1 Commercial Airlines. ... ... 212 Glossary

  • Can someone describe the nested set model from a C#/LINQ perspective?

    - by Chad
    I know the nested set model doesn't pertain to the C# language or LINQ directly... it's what I'm using to develop my web app. For hierarchical data (categories with sub-categories in my case), I'm currently using something similar to the Adjacency List model. At the moment, I've only got 2 levels of categories, but I'd like to take it further and allow for n levels of categories using the nested set model. I'm not quite clear on how to use it in a C# context. Here's the article I'm reading on the nested set model. Though this article cleared up my confusion some, I still have a big ?? in my head: - Is inserting, updating or deleting categories tedious? It looks like the left and right numbers would require re-numbering... what would the LINQ queries look like for the following scenarios? Delete a child node (re-number all node's left/right values) Delete a parent node (what do you do with the orphans?) Move a child node to a different parent node (renumber again) If my understanding is correct, at all times the child node's left/right values will always be between the parent node's left/right values, am I correct? Seems easy enough, if only the categories were static... most likely I need to spend more time to get my head around the concept. Any help is greatly appreciated!

  • Should nested attributes be automatically deleted when I delete the parent record?

    - by brad
    I'm playing around with nested forms in attributes and have a model Invoice that has_many invoice_phone_numbers. I have the following line in my invoice.rb model file accepts_nested_attributes_for :invoice_phone_numbers, :allow_destroy => true, :reject_if => proc { |attrs| attrs.all? { |k, v| v.blank? } } This does what it should and I can delete invoice_phone_numbers from the form by selecting their 'delete' checkbox. But when I delete an Invoice, I have noticed that the nested invoice_phone_numbers are not also deleted. This causes problems as rails seems to reuse id numbers in the Invoice model (Should it? Does this depend on the database? I'm using SQLite3) so phone numbers from previous invoices turn up in new invoices after they have been created. Anyway, my question is should the nested attributes be deleted when I delete the parent attribute? Is there a way to make this happen automatically as part of the nesting process or do I need to deal with this in my invoice model? If so, what is the best way to do this? I would try to go about this with a before_destroy callback but want to know if this is the best way to do this. Anyway, thanks.
