Is it possible to anti alias using Copy swap effect?

- by Nor

I'm developing an application in VB.Net using Managed DirectX that runs in windowed mode and renders onto a picture box that is smaller than the form. Whenever I resize the form, the back buffer is streched to fit the picture box. This is not what I would like. The backbuffer size is the same as screen size, however, I only want to render a part of the back buffer, whose size is controlled by the size of the picture box into which I'm rendering. Resetting the device with new presentation parameters is something I would like to avoid. I'm aware that I can use an overload of Device.Present if I set the swap effect to copy, but this doesn't allow me to use Multi Sample Anti Alias (which requires the Discard swap effect). It seems to me that the overload Device.Present is not usable with any other swap effect than copy, and throws an exception. An other alternative I considered is the PresentFlags.DeviceClip, however it seems that it works only for Windows XP. I'm using Windows 7 and it doesn't seem to be doing anything. So, is it even possible that I use anti-aliasing in this situation?

Visutal Studio Warning "Content is not allowed" in ASP.NET project

- by pstar

Hi, I am just started working as a programmer last month, so there will be plenty of newbie question come from me, stay tuned... I am now working on modify the provided template (from DevExpress) to create new web form using ASP.NET 2.0 on Visual Studio 2008. While the functionality of that web form is there, I am in the process of get rid of ninety something warning message, most of them come from the provided template. One of them puzzled me for a while is this one: "Warning 75 Content is not allowed between the opening and closing tags for element 'ClientSideEvents'." And here is the code: <dxe:ASPxListBox id="edtMultiResource" runat="server" width="100%" SelectionMode="CheckColumn" DataSource='<%# ResourceDataSource %>' Border-BorderWidth="0"> <ClientSideEvents SelectedIndexChanged="function(s, e) { var resourceNames = new Array(); var items = s.GetSelectedItems(); var count = items.length; if (count > 0) { for(var i=0; i<count; i++) _aspxArrayPush(resourceNames, items[i].text); } else _aspxArrayPush(resourceNames, ddResource.cp_Caption_ResourceNone); ddResource.SetValue(resourceNames.join(', ')); }"></ClientSideEvents> </dxe:ASPxListBox> I couldn't see anything wrong with the code myself, so please help me out here.

servlet connection to DB

- by underW

Initially, after reading books on the subject, I firmly believed that the algorithm for working with a database from a servlet is as follows: create a connection - connect to the database - form a request - send the request to the database - get the query results - process them - close connection - OK. Now, with a better understanding of the practical side, I realized that nobody does it that way, and everything happens through a connection pool according to the following algorithm: initialize the servlet - create a connection pool - a request comes from a user - take a free connection from the pool - form a request - send the request to the database - get the query results - process them - return the connection back to the pool - ok. Now I have this problem: We have 100 users, they are divided into 10 groups, each group has it's own username and password to connect to the database. Moreover, each group may have different rights to the database. How am I supposed to use a connection pool in this situation? If I understand correctly, a pool is nothing more than just a group of similar connections with a single login and password. And here I have 10 pairs of username / password. It looks like I cannot use the pool in this situation. What should I do?

Dropdownlist value not being set when there is a default blank option

- by uriDium

I am using ASP.Net MVC. I have a partial view which has a form with dropdownlists. The dropdownlists are set via ViewData. The partial view is used in a Create and Edit page. The create works fine. I get the dropdownlists and the blank option is a "Please select", like so <%= Html.DropDownList("ContactNrType", ViewData["ContactNrType"] as SelectList, "Please Select") %> But this doesn't seem to work for my edit. If I have that extra "Please select" parameter then it does not select the value for the drop down. I am setting the value of the drop down in the controller like so ViewData["ContactNrType"] = new SelectList(new List<string> { "Mobile", "Home", "Work", "Friend" }, candidate.ContactNrType); Any idea as to what I am doing wrong? I want to share the partial view which contains the form between the two pages. So I need the "Please Select" option for the Create. And I need the value set for the Edit (I don't mind that it has an option that still says "Please Select").

C#: Thread.CurrentThread.CurrentUICulture not working consistently

- by xTRUMANx

I've been working on a pet project on the weekends to learn more about C# and have encountered an odd problem when working with localization. To be more specific, the problem I have is with System.Threading.Thread.CurrentThread.CurrentUICulture. I've set up my app so that the user can quickly change the language of the app by clicking a menu item. The menu item in turn, saves the two-letter code for the language (e.g. "en", "fr", etc.) in a user setting called 'Language' and then restarts the application. Properties.Settings.Default.Language = "en"; Properties.Settings.Default.Save(); Application.Restart(); When the application is started up, the first line of code in the Form's constructor (even before InitializeComponent()) fetches the Language string from the settings and sets the CurrentUICulture like so: public Form1() { Thread.CurrentThread.CurrentUICulture = new CultureInfo(Properties.Settings.Default.Language); InitializeComponent(); } The thing is, this doesn't work consistently. Sometimes, all works well and the application loads the correct language based on the string saved in the settings file. Other times, it doesn't, and the language remains the same after the application is restarted. At first I thought that I didn't save the language before restarting the application but that is definitely not the case. When the correct language fails to load, if I were to close the application and run it again, the correct language would come up correctly. So this implies that the Language string has been saved but the CurrentUICulture assignment in my form constructor is having no effect sometimes. Any help? Is there something I'm missing of how threading works in C#? This could be machine-specific, so if it makes any difference I'm using Pentium Dual-Core CPU.

How to manipulate string to delete quotes?

- by user1751581

I am trying to manipulate a string so that any quotes (") within <a href> and <\a> get taken out... Sorry if its been asked before but I just can't get it to work! By the way, I am POSTing the data from a form and then manipulating the string. This is basically html but its in the form of a string, and I want to take out quotes on things like images and links... Another thing is, I do not want to escape the quotes because that would break the link... And the whole point is that the html can be used and work fine... But now, something is automatically creating a second set of quotes inside the normal quotes, like this: <a href="\"http://www.example.com/\""></a> Example input would be: <p><a href="http://www.example.com">example</a></p> Heres how it appears when I echo it however: <p><a href=\"http://www.example.com\">example</a></p> Heres how I want it to look: <p><a href="http://www.example.com">example</a></p> So I would actually be trying to get rid of the (/) my bad...

jQuery not working as expected on HTTPS Internet explorer

- by jat

When I try to run my code on any other webbrowsers apart from the Internet explorer it works fine. But when I try to run the code on Internet explorer I do get an alert box saying HERE along with an Ok button. but the problem is when I click on that OK button I do not get anything. Ideally I should be getting another alert box. <!DOCTYPE html> <html> <head> <script src="js/jquery-1.4.2.min.js"></script> <script type="text/javascript"> $(document).ready(function(){ $("#submit").click(function(event) { alert("here"); $.post('process.php', {name:'test1',email:'test.com'}, function(data) { $('#results').html(data); alert(data); }); }); }); </script> </head> <body> <form name="myform" id="myform" action="" method="POST"> <label for="name" id="name_label">Name</label> <input type="text" name="name" id="name" size="30" value=""/> <br> <label for="email" id="email_label">Email</label> <input type="text" name="email" id="email" size="30" value=""/> <br> <input type="button" name="submit" id="submit" value="Submit"> </form> <div id="results"><div> </body> </html> Any help on this is very much appreciated. Edit: I found out that Internet Explorer which has HTTP works perfectly fine but not on Internet Explorer which uses HTTPS.

Faster Javascript text replace

- by Stacey

Given the following javascript (jquery) $("#username").keyup(function () { selected.username = $("#username").val(); var url = selected.protocol + (selected.prepend == true ? selected.username : selected.url) + "/" + (selected.prepend == true ? selected.url : selected.username); $("#identifier").val(url); }); This code basically reads a textbox (username), and when it is typed into, it reconstructs the url that is being displayed in another textbox (identifier). This works fine - there are no problems with its functionality. However it feels 'slow' and 'sluggish'. Is there a cleaner/faster way to accomplish this task? Here is the HTML as requested. <fieldset class="identifier delta"> <form action="/authenticate/openid" method="post" target="_top" > <input type="text" class="openid" id="identifier" name="identifier" readonly="readonly" /> <input type='text' id='username' name='username' class="left" style='display: none;'/> <input type="submit" value="Login" style="height: 32px; padding-top: 1px; margin-right: 0px;" class="login right" /> </form> </fieldset> The identifier textbox just has a value set based on the hyperlink anchor of a button.

STI and accepts_nested_attributes_for in rails

- by ryanshackintosh

I have models as follows: class Entity < ActiveRecord::Base has_many :addresses accepts_nested_attributes_for :addresses, :reject_if => lambda { |a| a[:label].blank?} , :allow_destroy => true end class Client < Entity before_save :set_type private def set_type self.type = "Client" end end class Address < ActiveRecord::Base belongs_to :entity end I have recently implemented accepts_nested_attributes_for on the /clients/new form, as follows: <% form_for(@client, :html => {:class => 'form'}) do |f| -%> <%= f.label :name %> <%= f.text_field :name -%> <%= f.label :phone %> <%= f.text_field :phone %> <% f.fields_for :addresses do |a| %> <%= a.label :street %> <%= a.text_field :street%> <%= a.label :city %> <%= a.text_field :city %> <% end %> <% end %> And my controller as follows: class ClientsController < ApplicationController before_filter :load_client , :except => [:index, :new, :create, :render_clients] def new @client = Client.new @client.addresses.build end def create @client = Client.new(params[:client]) if @client.save flash[:notice] = 'Client has been successfully added' redirect_to @client else render :action => 'new' end end The issue is that when the record is saved it gives an error stating: "Entity can't be blank" I assume it is something to do with the fact that a 'Client' and not an 'Entity' is being added. Can anyone point me in the right direction?

How can i acced form another class file "Listbox's" Thanks for answers.

Best way to keep a .net client app updated with status of another application

- by rwmnau

I have a Windows service that's running all the time, and takes some action every 15 minutes. I also have a client WinForms app that displays some information about what the service is doing. I'd like the forms application to keep itself updated with a recent status, but I'm not sure if polling every second is a good move performance-wise. When it starts, my Windows Service opens a WCF named pipe to receive queries (from my client form) Every second, a timer on the winform sends a query to the pipe, and then displays the results. If the pipe isn't there, the form displays that the service isn't running. Is that the best way to do this? If my service opens the pipe when it starts, will it always stay open (until I close it or my service stops)? In addition to polling the service, maybe there's some way for the service to notify any watching applications of certain events, like starting and stopping processing? That way, I could poll less, since I'd presumably know about big events already, and would only be polling for progress. Anything that I'm missing?

Hiding Url for asp.net page

- by user204588

Hello, I'm creating an html page that is posted to another page for processing. I don't want users to see the weird URL they are redirected to and I was using FRAMES but I can't figure out how to add my HTML page dynamically because I need the variables and either add frames or try another way to accomplish this. So, based on how I'm creating the page below, how can I hide the URL and add something that I want. Here is how I'm creating the page. StringBuilder sb = new StringBuilder(); sb.Append("<html><head></head>"); sb.Append("<body onload=\"document.frmLaunch.submit();\">"); sb.Append("<form name=\"frmLaunch\" action=\"" + variableTargetURL + "\" method=\"post\">"); sb.Append("<input type=hidden name=\"testVariable\" value=\"" + variableTest + "\">"); sb.Append("</form>"); sb.Append("</body></html>"); HttpResponse response = HttpContext.Current.Response; response.Clear(); response.Write(sb.ToString()); response.End();

R Random Data Sets within loops

- by jugossery

Here is what I want to do: I have a time series data frame with let us say 100 time-series of length 600 - each in one column of the data frame. I want to pick up 4 of the time-series randomly and then assign them random weights that sum up to one (ie 0.1, 0.5, 0.3, 0.1). Using those I want to compute the mean of the sum of the 4 weighted time series variables (e.g. convex combination). I want to do this let us say 100k times and store each result in the form ts1.name, ts2.name, ts3.name, ts4.name, weight1, weight2, weight3, weight4, mean so that I get a 9*100k df. I tried some things already but R is very bad with loops and I know vector oriented solutions are better because of R design. Thanks Here is what I did and I know it is horrible The df is in the form v1,v2,v2.....v100 1,5,6,.......9 2,4,6,.......10 3,5,8,.......6 2,2,8,.......2 etc e=NULL for (x in 1:100000) { s=sample(1:100,4)#pick 4 variables randomly a=sample(seq(0,1,0.01),1) b=sample(seq(0,1-a,0.01),1) c=sample(seq(0,(1-a-b),0.01),1) d=1-a-b-c e=c(a,b,c,d)#4 random weights average=mean(timeseries.df[,s]%*%t(e)) e=rbind(e,s,average)#in the end i get the 9*100k df } The procedure runs way to slow. EDIT: Thanks for the help i had,i am not used to think R and i am not very used to translate every problem into a matrix algebra equation which is what you need in R. Then the problem becomes a little bit complex if i want to calculate the standard deviation. i need the covariance matrix and i am not sure i can if/how i can pick random elements for each sample from the original timeseries.df covariance matrix then compute the sample variance (t(sampleweights)%*%sample_cov.mat%*%sampleweights) to get in the end the ts.weighted_standard_dev matrix Last question what is the best way to proceed if i want to bootstrap the original df x times and then apply the same computations to test the robustness of my datas thanks

jQuery Validation Plugin ErrorPlacement inside two different elements

- by Andy Poquette

I'm trying to place separate error messages in separate elements when validating a large form. The form is divided into jQueryUI tabs, then accordions. When there is an error in an element of a tab, I want to append a red exclamation point to the name of the tab, and if the error is in an accordion element, I also want to append the red exclamation point to the name of the accordion element. Subsequently, when the errors are corrected, I would like those red ! to be removed (exactly as the error message beneath the invalid field is removed. So: Tab1 Tab2 Accordion1 Accordion2 Tab3 If the elements in accordion 2 have an error, I want to append a red ! to accordion2 and tab2: Tab1 Tab2! Accordion1 Accordion2! Tab3 Then remove when the elements successfully validate. I've been trying forever, but I can't figure out how to conditionally change the errorElement (a label won't work for the tab and accordion, but is perfect for the actual element)... Hopefully this makes sense, and thanks for any input you can provide.

Maximize/Minimize is causing Close Button to be re-enabled after disabling it -- Why?

- by Brainsick

I have used P/Invoke to call GetSystemMenu and EnableMenuItem (win32api) to disable the close functionality. However, after minimizing or maximizing my Windows Forms application the button is re-enabled. Obviously minimizing or maximizing is causing the behavior, but how? I'm not sure where to look to prevent this behavior. Should I be preventing the maximize and minimize behavior or is there something particularly wrong with the way in which I P/Invoked the calls? Once the application (main form) has loaded, I call the static method from a button click. class PInvoke { // P/Invoke signatures [DllImport("user32.dll")] static extern IntPtr GetSystemMenu(IntPtr hWnd, bool bRevert); [DllImport("user32.dll")] static extern bool EnableMenuItem(IntPtr hMenu, uint uIDEnableItem, uint uEnable); // SysCommand (WM_SYSCOMMAND) constant internal const UInt32 SC_CLOSE = 0xF060; // Constants used with Add/Check/EnableMenuItem internal const UInt32 MF_BYCOMMAND = 0x00000000; internal const UInt32 MF_ENABLED = 0x00000000; internal const UInt32 MF_GRAYED = 0x00000001; internal const UInt32 MF_DISABLED = 0x00000002; /// <summary> /// Sets the state of the Close (X) button and the System Menu close functionality. /// </summary> /// <param name="window">Window or Form</param> /// <param name="bEnabled">Enabled state</param> public static void EnableCloseButton(IWin32Window window, bool bEnabled) { IntPtr hSystemMenu = GetSystemMenu(window.Handle, false); EnableMenuItem(hSystemMenu, SC_CLOSE, MF_BYCOMMAND | (bEnabled ?

Why would 1.000 subforms in a db be a bad idea?

- by KlaymenDK

Warm-up I'm trying to come up with a good way to implement customized document forms. It's for a tool to request access to applications; each application will want to ask its own specific questions. The thing is, we have one kind of (common) user who needs to fill in and submit documents based on templates, and another kind of (super) user who needs to be able to define what each template needs to contain. One implementation option would be to use a form (with the basic mandatory stuff), and have that form dynamically include a subform appropriate to the specific task at hand. The gist of the matter is that we could (=will!) quite easily end up having many hundreds of different subforms! (NB. These subforms will be maintained in an automated manner, but that is another topic that may be considered outside the scope of this Question.) Question It's common knowledge that having a lot of views in a Notes database is Bad Thing. But has anyone tried pushing the number of forms or subforms and made any experiences regarding performance?
