• What web UI framework is most suitable for building dynamic pages / forms?

  - by waxwing

  Hello, We are at a stage where we are considering different Web UI frameworks (most likely component based ones such as GWT, JSF, Wicket, Vaadin, etc). One of the main use cases / constraints is that it must support generating dynamic pages. I.e., the page/form layout and components is stored in a database and is changeable at runtime, and from this pages are generated. We are also going to write static layouts, but that is not the main focus of this question. I thought maybe the user community here can share experiences of different frameworks in this context. Are there differences in ease of implementation and what is suitable?

• Failing to send key presses to a running process in C#

  - by Waffles

  I'm using the following code to put the focus on a window (in this case, a notepad window), and sending some key presses to it everytime button 2 is clicked. However, when I press button 2, nothing happens. Can anyone tell my why my sendkeys command is failing? public partial class Form1 : Form { [DllImport("user32.dll")] static extern bool ShowWindow(IntPtr hWnd, int nCmdShow); private Process s; public Form1() { InitializeComponent(); } private void button1_Click(object sender, EventArgs e) { this.s = new Process(); s.StartInfo.FileName = "notepad"; s.Start(); s.WaitForInputIdle(); } private void button2_Click(object sender, EventArgs e) { ShowWindow(s.MainWindowHandle, 1); SendKeys.SendWait("Hello"); } }

• Order database results by bayesian rating

  - by One Trick Pony

  I'm not sure this is even possible, but I need a confirmation before doing it the "ugly" way :) So, the "results" are posts inside a database which are stored like this: the posts table, which contains all the important stuff, like the ID, the title, the content the post meta table, which contains additional post data, like the rating (this_rating) and the number of votes (this_num_votes). This data is stored in pairs, the table has 3 columns: post ID / key / value. It's basically the WordPress table structure. What I want is to pull out the highest rated posts, sorted based on this formula: br = ( (avg_num_votes * avg_rating) + (this_num_votes * this_rating) ) / (avg_num_votes + this_num_votes) which I stole form here. avg_num_votes and avg_rating are known variables (they get updated on each vote), so they don't need to be calculated. Can this be done with a mysql query? Or do I need to get all the posts and do the sorting with PHP?

• Regex with dynamic <textarea>

  - by Oscar Godson

  How can I do this with the JS replace() method: Make \n\n change to <p>$1</p> Change single \n to <br> Then back again. I think I have this part, see the JS at the bottom. Example HTML: <p>Hello</p><p>Wor<br>ld</p> The <textarea> would look like: Hello Wor ld So, how can I achieve this? It's an AJAX form where when you click on this div it changes to a <textarea> and back, and fourth, etc. So, I need to it to go from <p>s and <br>s to \n\n and \n. For the going to <textarea> from HTML I have: $(this).html().replace(/\s?<\/?(p|br\s?\/?)>\s?/g,"\n")

• ASP.NET handling button click event before OnPreInit

  - by Phillykins

  Hello, I have a data access layer, a business logic layer and a presentation layer (ie. the pages themselves). I handle the OnPreInit event and populate collections required for the page. All the data comes from an SQL server database and I do not use caching. I handle a button click event to grab values from a form and insert a new object into the database. The problem is that by the time I handle the click event, the collections have already been populated, so the new item which has been inserted into the database has not been retrieved. What is the accepted solution to this? I could insert the new object directly into the collection and re-bind the GridView, but the SQL query selects only a set of objects and the new object could fall outside of this set. Thanks!

• Converting MS Word Documents to PDF in ASP.NET

  - by glaxaco

  Similar questions have been asked, but nothing exactly like mine, so here goes. We have a collection of Microsoft Word documents on an ASP.NET web server with merge fields whose values are filled in as a result of user form submissions. After the field merge, the server must convert the document to PDF and stream it down to the browser. Our first inclination was to use the Visual Studio Tools for Office API; however, we ran into this warning from Microsoft: Microsoft does not currently recommend, and does not support, Automation of Microsoft Office applications from any unattended, non-interactive client application or component (including ASP, ASP.NET, DCOM, and NT Services), because Office may exhibit unstable behavior and/or deadlock when Office is run in this environment. It looks like the field manipulation can be done using the Open XML SDK, but what's the best way to convert Word 2007 documents to PDF without opening Word? The optimal solution would be low-cost, scalable, have a low memory footprint, be easy to deploy, and have a .NET API.

• Restoring web session in struts2

  - by bozo

  Hi, I have a classical scenario of a website and payment gateway integration, where the request for payment is sent to payment processor, and the payment processor calls back my application once it's done with some parameters I passed to it in the original request. Among parameters, we pass jsessionid and we expect that when the remote server makes request to our server (via customer browser redirect to our server) that the session will be the same as the session used to send the initial payment request. This does not happen, we have two different sessions, although the payment processor includes our original jsessionid in the request to us (https://blabla/?jsessionid=something). How should we go about recreating a session in struts2, in the only thing that connects the 'OLD' and 'NEW' session is the jsessionid in the request URL? Any ideas? Is this possible at all or is the 'OLD' session data deleted when the user moves away from our server onto a completely different domain of a payment processor with their data-entry form? This would explain our innability to recreate the session. Thanks a lot for your replies.

• Loading embedded resource on Windows 7

  - by Flack

  Hello, I have an app that works just fine on my WinXP machine. However, when I try running it on my Win7 machine, it fails whenever it tries to load an embedded resource. The resources are all there (I can see them using Reflector). The lines that fail are all of the form: Splash.Image = new Bitmap(typeof(ContainerForm).Assembly.GetManifestResourceStream("SplashTest.Resources.Logo.gif")); And they all fail with the same exception: Exception='System.ArgumentException: Parameter is not valid. at System.Drawing.Bitmap..ctor(Stream stream) I don't understand why this is not working on my Win7 machine but does on my usual WinXP dev machine. Any ideas?

• reading 2 lines from IniFile

  - by Lakkerw

  Trying again. On advice, adding the piece of code that I do understand. I am fine with the fact that I have to save 4 bits of information in two lines like so: IniFile.WriteString('TestSection','Name','Country'); IniFile.WriteString('TestSection','City','Street'); My question is more about loading this information back into the form. If in my IniFile I have saved for example the following code [TestSection] John=Uk London=barlystreet Mike=Spain Madrid=eduardostrata Emma=USA New York=1st Avenue Made up information in the IniFile. Added through the code above. Now my question is: How could I load for example, when I type in an edit box Mike, the rest of the belonging information.(Spain, Madrid,eduardostrata).

• Is there a way for IIS6 to do http and https together in the same site?

  - by puffpio

  The site needs to be accessible both from HTTP and HTTPS (in case the client wants the form submissions to be secure or not) The site is hosted in IIS6 and ideally I'd like to be able to just have one website in there and it can handle both http and https..is this possible? alternatively i was thinking maybe creating a "secure" subdirectory in the site and duplicating everything in there as well..is that feasible? this is further complicated that it is using asp.net 3.5's routing ability to do url rewrites so even if I create a secure subdirectory, i dunno if it will actually pick up that it's supposed to be SSL approved

• How to collect user opinions about software

  - by alga

  I have written a small .net Windows Forms application. And now I decided to get opinions or comments from users. User will just write something in a input form and click a send button. I want to use the most easiest way. I don't want to host any webservices or another applications for gathering the information. Also I don't have a database. Nothing. I just want to know what people think about the application. How would you do it?

• Working with multiple input and output files in Python

  - by Morlock

  I need to open multiple files (2 input and 2 output files), do complex manipulations on the lines from input files and then append results at the end of 2 output files. I am currently using the following approach: in_1 = open(input_1) in_2 = open(input_2) out_1 = open(output_1, "w") out_2 = open(output_2, "w") # Read one line from each 'in_' file # Do many operations on the DNA sequences included in the input files # Append one line to each 'out_' file in_1.close() in_2.close() out_1.close() out_2.close() The files are huge (each potentially approaching 1Go, that is why I am reading through these input files one at a time. I am guessing that this is not a very Pythonic way to do things. :) Would using the following form good? with open("file1") as f1: with open("file2") as f2: # etc. If yes, could I do it while avoiding the highly indented code that would result? Thanks for the insights!

• Web2py controllers with parameters?

  - by nickfranceschina

  I am building an app using Web2py framework... I don't want to have to use the request object to get all of the querystring parameters, instead I'd like to build my controller with named parameters and have the router unpack the querystring (or form data) dictionary into the named parameters and call my controller. so instead of a controller method of create_user(): where I would use the global request() object and look through the vars list... I would prefer instead to have create_user(first_name, last_name, email): like I see in other MVC platforms. is this possible in Web2py already? or is there a plugin for it? or do I need to add that myself?

• WinForm - WPF integration; Piece by Piece

  - by Refracted Paladin

  I have a medium sized WinForm App (1 Form that hosts 40 user controls) that we use in house. I want to migrate over to WPF but I cannot do a Mass ReRelease. My idea was, for now, to recreate the App 1 User Control at a time in WPF and have that hosted in the existing WinForm App. I would make them look nearly identical, at this point, so there would be no need for mass retraining. My question is more to the point of, has any one else tried this and how does the data portion work. I have recreated one of the WinForms User Controls as a WPF user Control. Do I need to publish that as a User Control Library? How, then, would I access the DAL for that UC? I use a Linq to Sql data layer.

• 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?

• Are memcached entries saved by the Danga client compatible with the Spy client?

  - by jigjig

  After saving a String value into memcached using the Danga client, I attempted to get the entry using the Spy client. The two String values are not the same. The Danga client retrieves a string with an additional empty char prepended to the string, therefore violating the equality condition. Danga: t,e,s,t,s,t,r,i,n,g Spy: ,t,e,s,t,s,t,r,i,n,g I also attempted to save a serialized Map using the Danga client and get the Map using the Spy client. The Spy client is able to only get a String form of the Map. The string contains binary values, as below: sr

• Finding Cities within 'X' Kilometers (or Miles)

  - by Mike Curry

  This may or may not be clear, leave me a comment if I am off base, or you need more information. Perhaps there is a solution out there already for what I want in PHP. I am looking for a function that will add or subtract a distance from a longitude OR latitude value. Reason: I have a database with all Latitudes and Longitudes in it and want to form a query to extract all cities within X kilometers (or miles). My query would look something like this... Select * From Cities Where (Longitude > X1 and Longitude < X2) And (Latitude > Y1 and Latitude < Y2) Where X1 = Longitude - (distance) Where X2 = Longitude + (distance) Where Y1 = Latitude - (distance) Where Y2 = Latitude + (distance) I am working in PHP, with a MySql Database. Open to any suggestions also! :)

• Picking Up Repositories With Structuremap

  - by alphadogg

  I am not sure how to use StructureMap to scan for all repositories in a particular namespace. Most repositories take the form: namespace CPOP.Infrastructure.Repositories { public class PatientRepository : LinqRepository<Patient>, IPatientRepository { } } namespace CPOP.Infrastructure.Repositories { public class LinqRepository<T> : Repository<T>, ILinqRepository<T> { } } namespace CPOP.Domain.Contracts.Repositories { public interface IPatientRepository : ILinqRepository<Patient> { } } I tried: x.Scan(scanner => { scanner.Assembly(Assembly.GetExecutingAssembly()); scanner.ConnectImplementationsToTypesClosing(typeof(ILinqRepository<>)); }) But, it only picks up the LinqRepository class. What's the best way to pick up the various repositories I'll be dumping in there?

• How can I change text on a win32 window?

  - by Will

  Looking for hints, tips and search terms for changing the text on a win32 window from C#. More specifically, I'm trying to change the text on the print dialog from "Print" to "OK", as I am using the dialog to create a print ticket and not do any printing. How can I find the dialog's window handle? Once I've got it, how would I go about finding the button in the child windows of the form? Once I've found that, how would I change the text on the button? And how can I do all this before the dialog is shown? There's a similar question here, but it points to a CodeProject article that is waaay more complex than needed and is taking me a bit longer to parse through than I'd like to spend on this. TIA.
