• IIS, Impersonation and COM Interop Premission Denied

  - by user315690

  Hello we are in the throws of integrating a Document Management System with Dynamic CRM 4, have done similar things previously but in this instance we are having to reference a COM dll. We've configured the asp.net page (we are bringing the info in via a i-Frame in CRM), setting Impersonation = True in the Webconfig and ensured that Windows authentication is the only method available within IIS. All works as we would expect when logged into the server itself and the page happily does off finds all the relevant documents for the CRM account and presents them to a user in a nice Infragistics CRM styled grid. However trying this from a client workstation we get the following: System.Runtime.InteropServices.COMException (0xC0042335): Permission denied. Impersonation appears to be passing over the correct details but nothing we've tried thus far has been able to make this work outside of logging into the server. Any thoughts as to what we are missing?

• PushViewController after presentModalViewController like in Apples Alarm Clock app

  - by Fabian

  Hello together, my Question is quite simple. I have an add-button. When I tap on it -- presentmodelviewController presents a UIViewController, which contains a simple Table with cells. When I tap on a Cell, i want to display a new View using pushViewController, which automatically creates a "back Button". At the top of it in this new View i have a Textfield, where I can enter some Text. When I tap the back-button, the view slides back to the add-View (which was presented using modalView...). Now i want the text edited in the view before to be placed in the Label of the first row (cell) on which I tapped. So I want to do this for 5 cells. Each of them presenting another xib. Please, can anyone help? Thanks for your helpful replies.

• Data validation: fail fast, fail early vs. complete validation

  - by Vivin Paliath

  Regarding data validation, I've heard that the options are to "fail fast, fail early" or "complete validation". The first approach fails on the very first validation error, whereas the second one builds up a list of failures and presents it. I'm wondering about this in the context of both server-side and client-side data validation. Which method is appropriate in what context, and why? My personal preference for data-validation on the client-side is the second method which informs the user of all failing constraints. I'm not informed enough to have an opinion about the server-side, although I would imagine it depends on the business logic involved.

• Just-in-time invocation of Facebook login window from UIWebView

  - by Chris Garrett

  I have an app that presents a UIWebView pointing to my own server. I have a Facebook Like button on some pages inside the UIWebView. I have it working now, but the login screen is way too big for the phone screen. I would like to present a nicer login dialog such as the one in the Facebook iPhone API, and then continue back to the web view. The Facebook iPhone SDK has support for a login button and iPhone-friendly login screen, but it assumes that a user will click a login button before doing anything Facebook related. I would like the Like button to just appear, and to bring up the iPhone login screen only when necessary. I have monitored HTTP requests from my web view, and it looks like I could intercept the login request there, and present the login dialog. However, it seems that this would be fragile, because if Facebook changes those calls then my app will no longer work. Is there a more elegant way to do this?

• Why can I not install ASPNET MVC2 from the Web Platform Installer? (Error: "requires VS2008 SP1", bu

  - by Cheeso

  I went to http://www.asp.net/mvc/ to try to install ASP.NET MVC. I didn't know, but MVC is now at version 2. There's a nifty thing called the Microsoft "Web Platform Installer" (WPI) which basically is a small installer-driver tool that presents a menu of things I might want to install, to do web things on Windows. On the menu are things like ASPNET MVC2, but also Drupal, PHP, Joomla, and a bunch of other things. From http://www.asp.net/mvc/, when I click on the link that says "Install MVC", it resolves to http://go.microsoft.com/fwlink/?LinkID=185037, which then pops up the WPI. But Then! I get an error dialog that reads "Installing ASPNET MVC2 requires VS2008 SP1". But I know that I have VS2008 SP1. What gives?

• Gridview with row headers

  - by Seagull

  I am using the ASP.NET3.5 gridview control in a new project. My problem is that the gridview presents data in basic tabular format, whereas I want a grid with row header / grouping behaviors. An example of this would be Outlook web interface, which can group emails by date, as well as allowing you to select individual emails to display. My problem: I can't see how this could be easily done with Gridview? I did find a product called Telerik that has a seemingly fancy Gridview, but I am hesitant to spend money on a single components that now also locks me into a third-party framework...

• Robustly killing Windows programs stuck reporting 'problems'

  - by grrussel

  I am looking for a means to kill a Windows exe program that, when being tested from a python script, crashes and presents a dialog to the user; as this program is invoked many times, and may crash repeatedly, this is not suitable. The problem dialog is the standard reporting of a Windows error: "Foo.exe has encountered a problem and needs to close. We are sorry for the inconvenience" and offers a Debug, Send Error Report, and Don't Send buttons. I am able to kill other forms of dialog resulting from crashes (e.g. a Debug build's assert failure dialog is OK.) I have tried taskkill.exe, pskill, and the terminate() function on the Popen object from the subprocess module that was used to invoke the .exe Has anyone encountered this specific issue, and found a resolution? I expect automating user input to select the window, and press the "Don't Send" button is one possible solution, but I would like something far simpler if possible

• Is there a way to watch all COM activity on a computer?

  - by Fake Name

  I'm trying to deal with a piece of specialized hardware, that presents it's interface as a COM object, using win32com in Python. However, the documentation for how to actually set up the hardware through the COM object is sparse (it requires a significant amount of initialization), and entirely oriented at using a bunch of pre-built libraries for Visual Studio, which are not accessible through python. That said, is there any way to watch all local COM activity, so I can sort through the activity logs to try and figure out how the existing demo programs properly initialize the hardware, and replicate the behavior in my python script? Ideally, there would be something in the vein of wireshark for doing this. Note: I have very little (read: basically no) experience using COM, as my focus is mostly embedded hardware (and a little python dev on the side). However, I'm stuck with this particular device.

• Java Backgroundworker: Scope of Widget to be updated unclear

  - by erlord

  Hi all, I am trying to understand the mechanism of org.jdesktop.swingx.BackgroundWorker. Their javadoc presents following example: final JLabel label; class MeaningOfLifeFinder implements BackgroundListener { public void doInBackground(BackgroundEvent evt) { String meaningOfLife = findTheMeaningOfLife(); evt.getWorker().publish(meaningOfLife); } public void process(BackgroundEvent evt) { label.setText("" + evt.getData()); } public void done(BackgroundEvent evt) {} public void started(BackgroundEvent evt) {} } (new MeaningOfLifeFinder()).execute(); Apart from the fact that I doubt the result will ever get published, I wonder how label is passed to the process method, where it is being updated. I thought it's scope is limited to the outside of the BackgroudListener implementation. Quite confused I am ... any answers for me? Thanks in advance

• How to build an interactive search engine web interface using python

  - by asmaier

  I have build a static web interface for searching data from some tables in my PostgreSQL database. The query website consists of a simple textfield for entering the search term, the result website presents the results as a simple html table. The server side code for searching the PostgreSQL database and returning the results is written in python using psycopg2. Now I would like to add some interactive "Ajax features" to my search engine. When entering the search term I would like to be able to see a list of possible search terms like Google does it. On the results page, I would like to be able to sort the table showing the results. What would be the easiest/recommended way to implement these features for my search engine web site? Do I need a full-fledged web framework like Django for that?

• iPhone - Browsing iPhone files through computer

  - by quano

  I want to be able to send files from an iPhone app to a computer. What would be the easiest way of doing this? I've made simple server client programs before, but in those, the client has always needed to connect to the server before being able to receive messages from it. There is an app for the iPhone called iSimulate, where you put a server on a Mac (the iPhone simulator), and then you use the iSimulate app of an iTouch or iPhone to send touch events to the server. This app does not require you to type in an ip-address. Instead it presents a list of available computers that have this server up and running. How exactly is this being done? Can a server broadcast a message over a network, w/o anyone being connected to the server? How does that work? How does a client listen for that broadcast? Here's a video of the app I'm talking about: http://www.youtube.com/watch?v=N3Qpd1ycZh4

• Silverlight 5 App Crashing

  - by bbagfh

  I have a silverlight 5 app that makes some WCF requests. When the silverlight app is hosted locally on an IIS 7.5 server it works fine, but when I run it from a remote IIS6 box there are issues. The app loads fine and presents the login UI. After trying to log in, a couple WCF service calls are made (successfully), but the response causes silverlight to stop responding and the browser eventually asks to kill the non-responsive silverlight app. I am mostly confused because it works fine in IIS 7.5 Note that I am accessing the same WCF services hosted on a remote box in both instances, and both times I am getting successful responses. It is only in IIS6 that the app becomes non-responsive.

• How to get Resharper to show a Refactoring that it already has.

  - by AngryHacker

  Whenever Resharper encounters code like this: (treeListNode.Tag as GridLine).AdvertiserSeparation = 5; it presents you with a possible fix (since treeListNode.Tag as GridLine might be null). It says: 'Replace with Direct Cast', which turns the code into the following: ((GridLine) treeListNode.Tag).AdvertiserSeparation = 5; This is great. However, when it encounters code like this: GridLine line = treeListNode.Tag as GridLine; line.AdvertiserSeparation = 5; Resharper simply displays a warning 'Possible System.NullReferenceException', but does not offer me to 'Replace with Direct Cast'. Is there a way to make Resharper offer me this refactoring, since it already has it?

• Start thread with two parameters

  - by Matt

  I've got a method that gets called on an event, which presents me with two variables varA, varB (both strings). This method gets called with new information quite frequently, thus I have created a separate method that takes in the two parameters. I want to run this method in a thread, however have struck the issue that Thread.Start will not accept parameters. I've tried a few supposed methods, but have so far had no luck.. I think my best bet is to create a separate class, and handle it there.. However I have a List which I am inserting data into, and hit a dead end when the separate class tried to access that list, since it was in a different class. Can someone help me out here please?

• trying to use ActiveRecord with Sinatra, Migration fails question

  - by David Lazar

  Hi, running Sinatra 1.0, I wanted to add a database table to my program. In my Rakefile I have a task task :environment do ActiveRecord::Base.establish_connection(YAML::load(File.open('config/database.yml'))["development"]) end I have a migration task in my namespace that calls the migration code: namespace :related_products do desc "run any migrations we may have in db/migrate" task :migrate => :environment do ActiveRecord::Migrator.migrate('db/migrate', ENV["VERSION"] ? ENV["VERSION"].to_i : nil ) end My console pukes out an error when the call to ActiveRecord::MIgrator.migrate() is made. rake aborted! undefined method `info' for nil:NilClass The migration code itself is pretty simple... and presents me with no clues as to what this missing info class is. class CreateStores < ActiveRecord::Migration def self.up create_table :stores do |t| t.string :name t.string :access_url t.timestamps end end def self.down drop_table :stores end end I am a little mystified here and am looking for some clues as to what might be wrong. Thanks!

• ASP.NET MVC based CMS - dynamic generation of form helpers

  - by user252160

  I am working on an ASP.NET MVC based CMS that presents a rather extreme case. The system must allow the user to add custom content types based on different fields, and for every field, one can add options and validations. The thing is that everything is stored in a complex DB and extracted at runtime using LINQ. I am pretty fresh with ASPNET MVC so the following dilemma came to mind How should I make the content creation view so that form helpers are not predefined int he view code but are loaded based on the type of the field ? Do I have to create a factory class that checks the value of the type property of the field, and then returns a helper based on that or there's a better way to do it. This one seems pretty rigid to me , because anytime I make a change in the Fieldtypes table, I will have to make sure to create a check for that new type too.

• Error: A SQLParamenter wtih ParameterName @myparm is not contained by this SQLParameter Collection

  - by SidC

  Good Morning, I'm working on an ASP.NET 3.5 webforms application and have written the following code: Protected Sub btnSubmit_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnSubmit.Click Dim connectionString As String = WebConfigurationManager.ConnectionStrings("Diel_inventoryConnectionString").ConnectionString Dim con As New SqlConnection(connectionString) Dim adapter1 As New SqlDataAdapter adapter1.SelectCommand = New SqlCommand adapter1.SelectCommand.CommandType = CommandType.StoredProcedure adapter1.SelectCommand.CommandText = "PartSproc" Dim parmNSN As New SqlParameter("@NSN", SqlDbType.NVarChar) Dim parmName As New SqlParameter("@PartName", SqlDbType.NVarChar) txtNSN.Text = adapter1.SelectCommand.Parameters("@NSN").Value txtSearch.Text = adapter1.SelectCommand.Parameters("@PartName").Value Dim dt As New DataTable() adapter1.Fill(dt) MySearch.DataSource = dt MySearch.DataBind() End Sub When I run the page, I receive the error A SQLParameter with @NSN is not contained by this SQLParameter Collection. I tried using apostrophes around the @NSN and @PartName but that does not work either and presents expression expected error. How might I rectify the above code so that it references the @NSN and @PartName parameters correctly? Thanks, Sid

• General zoom algorithm for drawing program

  - by Steven Sproat

  My GUI toolkit, wxPython provides some methods for implementing a user zoom factor, however the quality isn't too good. I'm looking for ideas on how to create a zooming feature, which I know is complicated. I have a bitmap representing my canvas which is drawn to. This is displayed inside a scrolled window. Problems I forsee: - performance when zoomed in and panning around the canvas - difficulties with "real" coordinates and zoomed in coordinates - image quality not degrading with the zoom Using wxPython's SetUserScale() on its device contexts presents image quality like this - this is with a 1px line, at 30% zoomed in. I'm just wondering the general steps I'll need to take and the challenges I'll encounter. Thanks for any suggestions

• json object composition details

  - by Ethan

  in .json text, is the 'value' in a basic single pair object the title of a value type (e.g. [string, number, object]), or a value for a typed object (e.g. 2, or "dog", or Object3)? This is how http://www.json.org/ presents the information: "An object is an unordered set of name/value pairs. An object begins with { (left brace) and ends with } (right brace). Each name is followed by : (colon) and the name/value pairs are separated by , (comma)."

• How to achieve table like rows within container using CSS

  - by Barry

  I'm helping an artist maintain her website and have inherited some pretty outdated code. Have moved lots of redundant common code to include files and am now working on moving from inline styles to more CSS-driven styles. For the gallery pages, e.g. http://artistsatlaketahoe.com/abstract.html, a lot of inline styling is used to force the current layout. My preference would be to replace this entirely with CSS that presents the following table-like layout within the "content" div: [image] [image descriptives and purchase button] [image] [image descriptives and purchase button] [image] [image descriptives and purchase button] I'd like to middle-align the image descriptives & purchase button relative to the image if possible. And then apply some padding above and below each row to stop using tags for vertical spacing. Any ideas how to create a div that I can use to get this kind of layout? Thanks!

• Java: I am trying to server a zip file through a link, but the file comes out as being empty

  - by Ankur

  I am trying to server a zip file through a link, but the file comes out as being empty. My app takes a number of files and zips them up, then presents the user with a link to the file so he/she can download it. On the server I can see that the zip file is being created correctly, but when I download it from the server through the normal HTML link provided no data is downloaded i.e. a zip file is created locally but it has file size 0kb. The file names are of the form XPCS.2010-03-09.15.13.42.165.zip - will the dots cause problems?

• Looking for solution to persist rows sequence in a database table that allow efficient reordering at

  - by Chau Chee Yang

  I have a database table. There is a field name "Sequence" that indicate sequence when user presents the rows in report or grid visually. When the rows are retrieved and presented in a grid, there are few UI gadget that allow user to reorder the rows arbitrary. The new sequence will be persist in database table when user commit the changes. Here are some UI operations: Move to first Move to last Move up 1 row Move down 1 row multi-select rows and move up or down multi-select rows and drag to new position For operation like "Move to first" or "Move to Last", it usually involve many rows and the sequence those rows would need to be updated accordingly. This may not be efficient enough at runtime. It is a common practice to use INTEGER as sequence's data type. Other solution is using "DOUBLE" or "FLOAT" that could overcome the mass update of row sequence but we will face problem if we reach the limit of precision.

Now, this presents some problems: Cant set size of each piece, therefore, each piece JPanel ocupy the whole JFrame, concealing the rest of the pieces and the background (gameboard). Cant set the position of the pieces. I have the default flow manager. Tried setbounds and no luck. Perhaps i should make the piece to extend other JComponent?

• Giant online image gallery - How do I avoid OutOfMemoryError?

  - by Ben L.

  For anyone who's wondering, the gallery is http://www.spore.com/sporepedia. My app uses the Spore API to get the 100 newest creations, then displays them in a GridView. The text data about the creations is easy to store, but the images present a problem. As far as I know, I can either keep the images in a Hashtable or grab them every time they are viewed. Neither of these will work - the Hashtable quickly presents an OutOfMemoryError, and the constant reloading causes a lot of load on the server and a lot of lag on the client. Is there a better way to store the images?
