• Lightbox for embeddable JavaScript widget? Like Feedback tabs for UserVoice/GetSatisfaction

  - by Eliot Sykes

  There are so many lightboxes to choose from, I'm looking for a very lightweight one to use in an embedded javascript widget that would be used on a number of different web sites. This would work in a similar way to the GetSatisfaction/UserVoice feedback tab. Here are the requirements for the lightbox: Very small javascript download (animation not needed) Self contained, not dependent on any libraries such as jquery, etc. Works in major browsers Lightbox displays HTML content from a given URL Close button (like GetSatisfaction or UserVoice) Dims background Avoids javascript namespace conflicts (or can easily be made to avoid them) CSS styling of lightbox does not interfere with site styling Have you used an existing lightbox scripts for this same purpose with similar requirements? Did you roll your own? Insights welcome! Thanks, Eliot

• can router configuration cause decreasing of download rate?

  - by Behrooz

  my download speed got crazy since i changed the routers IP. but nothing got fixed after "reset factory"ing it. the speed was 1024kb/s(128kB/s) but it is 200kb/s(max) right now. i mean it works good if a request is small(i.e. a HTTP request) but it gets slow if a request has a big response. help me please(it is three days I'm downloading VS2010) http://serverfault.com/questions/135243/ no one on serverfault helped me for posting my question please migrate it to serverfault. thanks.

• merging two duplicate contacts/CfoldFusion

  - by jil

  having to do with data integrity - I maintain a coldfusion database at a small shop that keeps addresses of different contacts. These contacts sometimes contain notes in them. When you are merging two duplicate contacts, one may be created in 2002 and one in 2008. If the contact in 2002 has notes prior to 2008, my question would be does it matter if you merge these contacts and keep the 2008 contact's ID number? Would that affect the data integrity or create any sort of issues with the notes earlier than 2008? I hope I've accurately described my scenario, as I am not familiar with the proper technical terms. I really appreciate the help sir!

• How can I provide a different rendering target to Direct2D?

  - by fingerprint211b

  I'm using Direct2D in C# to render a small gui framework for my research project. I'm not very used to working on Windows or with DirectX. I'm using a Windows Forms control to create a render target, and msdn warns that since it uses BindDC, a the larger the rendering target, the worse the performance will be (which turned out to be a dramatic difference, when I maximize the window, I get around 15 fps). What would be a better way to create a render target for Direct2D? Is there a way to create a window and render directly to it, instead of rendering to a control's buffer first, and then rendering that? If so, how? Sorry if my English sucks, not my native language.

• Flash video hiding the cursor on Mac OS X

  - by Tibor

  I found a Core Graphics function, CGCursorIsVisible, that one can use to determine whether the mouse cursor is shown on screen. I have a small app that uses a timer to call that function a few times a second to see if the cursor is shown or hidden (as I found no way to get my app notified when the mouse cursor shown/hidden status changes). The above works correctly except… when the Flash browser plugin plays a video: the mouse cursor gets hidden after a few seconds of mouse inactivity but CGCursorIsVisible() still keeps telling me that the cursor is indeed shown as if nothing happened. What I need is to be able to tell, at any given moment, whether the mouse cursor is shown to the end user on any screen. Is there any way to do that even in the case of playing a video using the Flash plugin?

• Finding the FORM that an element belongs to in JavaScript

  - by Magnus Smith

  How can I find out which FORM an HTML element is contained within, using a simple/small bit of JavaScript? In the example below, if I have already got hold of the SPAN called 'message', how can I easily get to the FORM element? <form name="whatever"> <div> <span id="message"></span> </div> </form> The SPAN might be nested within other tables or DIVs, but it seems too long-winded to iterate around .parentElement and work my way up the tree. Is there a simpler and shorter way? If it wasn't a SPAN, but an INPUT element, would that be easier? Do they have a property which points back to the containing FORM? Google says no...

• Sharepoint calendar webpart change views

  - by Jason

  Hi there, I created a calendar list, and I added the calendar web part in another web part page. I noticed that i can not change the view without going to edit mode, then go to modify shared web part. But in the home page of the calendar. There is a same calendar web part with a drop down menu to change views. Also, there is a small calendar connected to the main calendar web part in the left navigation area. I don't know how to add it to my web part page. How can i make it look the same on my web part page? Thanks, Jason

• Experiences with UI Automation and WPF

  - by soren.enemaerke

  We are developing a rather large WPF based application and would like to include some automated UI testing in our test suite (which already contains a number of unit tests). The UI Automation Framework from Microsoft partly sounds like a perfect fit for programatically launching and interacting with the application in a test setup. However, I've struggled to find solid references for samples and experiences with the technology, the articles and small samples available on MSDN is not enough to convince me that it is a solid choice. So, does anybody have real world experiences using the UI Automation Framework in their test suite? What are the caveats and the gotchas? Any best practices when written tests scripts, can you "record and replay" to a scriptable format, how much should you facilitate the testing from the application, how did you incorporate it in the automatic build? Should we be looking in another direction than the UI Automation Framework? Feel free to post you experiences here or link to some good references I might have missed

• Using PHP and SQLite

  - by Barry Shittpeas

  I am going to use a small SQLite database to store some data that my application will use. I cant however get the syntax for inserting data into the DB using PHP to correctly work, below is the code that i am trying to run: <?php $day = $_POST["form_Day"]; $hour = $_POST["form_Hour"]; $minute = $_POST["form_Minute"]; $type = $_POST["form_Type"]; $lane = $_POST["form_Lane"]; try { $db = new PDO('sqlite:EVENTS.sqlite'); $db->exec("INSERT INTO events (Day, Hour, Minute, Type, Lane) VALUES ($day, $hour, $minute, $type, $lane);"); $db = NULL; } catch(PDOException $e) { print 'Exception : '.$e->getMessage(); } ?> I have successfully created a SQLite database file using some code that i wrote but i just cant seem to insert data into the database.

• Implementing Brainf*ck loops in an interpreter

  - by sub

  I want to build a Brainf*ck (Damn that name) interpreter in my freshly created programming language to prove it's turing-completeness. Now, everything is clear so far (<+-,.) - except one thing: The loops ([]). I assume that you know the (extremely hard) BF syntax from here on: How do I implement the BF loops in my interpreter? How could the pseudocode look like? What should I do when the interpreter reaches a loop beginning ([) or a loop end (])? Checking if the loop should continue or stop is not the problem (current cell==0), but: When and where do I have to check? How to know where the loop beginning is located? How to handle nested loops? As loops can be nested I suppose that I can't just use a variable containing the starting position of the current loop. I've seen very small BF interpreters implemented in various languages, I wonder how they managed to get the loops working but can't figure it out.

• typesafe NotifyPropertyChanged using linq expressions

  - by bitbonk

  Form Build your own MVVM I have the following code that lets us have typesafe NotifyOfPropertyChange calls: public void NotifyOfPropertyChange<TProperty>(Expression<Func<TProperty>> property) { var lambda = (LambdaExpression)property; MemberExpression memberExpression; if (lambda.Body is UnaryExpression) { var unaryExpression = (UnaryExpression)lambda.Body; memberExpression = (MemberExpression)unaryExpression.Operand; } else memberExpression = (MemberExpression)lambda.Body; NotifyOfPropertyChange(memberExpression.Member.Name); } How does this approach compare to standard simple strings approach performancewise? Sometimes I have properties that change at a very high frequency. Am I safe to use this typesafe aproach? After some first tests it does seem to make a small difference. How much CPU an memory load does this approach potentially induce?

• In-Memory SQL-CE

  - by harley.333

  Is there a way to connect to a SQL-CE database as a stream? Specifically, our ASP.Net application builds small SDF at runtime for off-line needs. When the user is done with his off-line duties, he uploads the SDF and the application imports the new and updated data. No problems there. Currently, we're saving the uploaded SDF to the web-server's hard-drive and connecting to the file. Can we connect to the uploaded SDF without saving it to the hard-drive? We are using the DbProviderFactory.CreateConnection method, but we're open to suggestions.

• Slow SQLite access on iPhone

  - by georgij

  I have a quite slow data retrieval from a sqlite database on my iPhone and perhaps someone have an alternative idea to explain this. From what I tracked down so far sqlite3_step(statement) is sometimes unusually slow. While retrieving e.g. 50 rows from the database to execute this step takes normally some milliseconds but sometimes it takes several seconds. My database is not small (80MB) and my theory is that the reason is paging. But can someone else think of an other reason for this?

• Capture Silverlight 4 event when panel clicked

  - by Eric J.

  I have a small Silverlight 4 app that essentially consists of a grid containing a label and a combo box. When I click the label, I replace it with a second text box so that I can edit the label (much the way you can edit the name of a Silverlight control in VS2010). I have a LostFocus event handler on the text box that will end editing when the control loses focus (restoring the updated label). Trouble is, users tend to click on the panel when they are done editing rather than on another control (or hitting Enter, which is also supported). I tried adding a left mouse down event handler to the panel. However, that only fires when the text box does not have the focus (I guess the text box captured the mouse?) Is there an approach to recognize that a non-input control was clicked that would enable me to terminate edit mode?

• How to use Page Object pattern with Cucumber and Webrat / Selenium?

  - by Will Sargent

  I'm looking at a cucumber test suite that is somewhat brittle right now; many small steps, and no knowledge of the page itself. I'd like to factor out the logic involved in the step definitions inside a series of Selenium PageObjects. As seen here. However, because I'm using Webrat and not Selenium, everything has to go through the Webrat model. So I cannot do class MyPage < Selenium::WebPage end because that adds a direct dependency. So I have to route everything through Webrat while still maintaining the Selenium Page object goodness. No documentation on this that I can see: if someone has anything on Webrat + PageModel I'd love to see it.

• OpenNETCF DirectShowPlayerControl display is going black randomly when playing videos if the player

  - by Sundar

  I have a application that runs on touch enabled device with WinCE 3.5 OS. I have a show player control to display adds when the system is left idle for some configured amount of time.. So the DirectShowPlayerControl will be iniated every time the show player is launched and will be destroyed when it is closed... The player for the first time plays videos continuously for any amount of time. Once the player is destroyed and recreated the video are changing but the display goes black and in between if some small video is placed that alone is displayed. Whenever the form is closed am calling DirectShowPlayerControl.Dispose() method.

• How to get a clipboard paste notification and provide my own data?

  - by Uwe Keim

  For a small utility I am writing (.NET, C#), I want to monitor clipboard copy operations and clipboard paste operations. My idea is to provide my own data when pasting into an arbitrary application. The monitoring of a copy operation can be easily done by using a clipboard viewer. Something that seems much more advanced to me is to write a "clipboard paste provider": Answer to "what formats are available" queries of applications. Supply data to application paste operations. I found this posting and this posting, but none of them seems to really help me. What I guess is that I somehow have to mimic/hijack the current clipboard. Question: Is it possible to "wrap" the clipboard in terms of paste operations and provide my own kind of "clipboard proxy"? Thanks Uwe

• iPhone, Convenience Method or Alloc / Release?

  - by fuzzygoat

  Whilst developing for the iPhone I had a stubborn memory leak that I eventually tracked down to NSXMLParser. However whilst looking for that it got me thinking about maybe changing a lot of my convenience methods to alloc/release. Is there any good reason for doing that? In a large app I can see how releasing memory yourself quickly is a better idea, but in a small app is there any other difference between the two methods. NSNumber *numberToAdd = [NSNumber numberWithInt:intValue]; dostuff ... OR NSNumber *numberToAdd = [[NSNumber alloc] initWithInt:intValue]; doStuff ... [numberToAdd release]; cheers gary.

• Javascript: variable in outer function not changed by inner function

  - by Weng-Lock Mok

  I am having a small issue with what I believe is probably my misunderstanding of Javascript closures. I have this piece of code -- getStdOpts: function(tbl, filt) { var vals = new Array(); this.srvs.getStdOptions( { tbl: tbl }, { 'ok': function(rsp) { for (var i in rsp) { vals.push({ value: rsp[i].id, text: rsp[i].descr }); } } } ); return vals; } In essence, although the inner function inside the getStdOptions call ('ok': function...) pushes new values into the vals array, when accessed from outside the call, the vals array is empty. When accessed from within the inner function, vals contains all the elements as expected. Would really appreciate any help I can get on this matter.

• SSD and programming

  - by Simon Johnson

  I'm trying to put together a business case for getting every developer in our company an Intel SSD drive. The main codebase contains roughly 400,000 lines of code. My theory is that since the code is scattered about in maybe 1500 files, an SSD drive would be substantially faster for compiles. The logic being that many small reads really punishes the seak-time bottle-neck of a traditional hard-drive. Am I right? Is SSD worth the money in productivity gains by reducing the edit/compile cycle time?

• Changing drag cursor in VirtualTreeView

  - by Coder12345

  When using VirtualTreeView drag operation by default is [doCopy,doMove]. Move operation is indicated by arrow pointer with small box and Copy operation is indicated by same pointer icon but with added [+] next to it. By default VT uses copy operation and if you press modifier key (SHIFT key) it modifies operation to move therefore removing the [+] from pointer. Here is what I need: reverse the operations (default would be move, with modifier key pressed - copy) and thus reverse pointer arrow too replace modifier key - CTRL instead of SHIFT read in an event which of the two operations occurred and start copy or move operation Any pointers into right direction(s) appreciated.

• Decoding subsampled bitmaps in Android

  - by hgpc

  I decode bitmaps from the SD card using BitmapFactory.decodeFile. Sometimes the bitmaps are bigger than what the application needs or that the heap allows, so I use BitmapFactory.Options.inSampleSize to request a subsampled (smaller) bitmap. The problem is that the platform does not enforce the exact value of inSampleSize, and I sometimes end up with a bitmap either too small, or still too big for the available memory. From http://developer.android.com/reference/android/graphics/BitmapFactory.Options.html#inSampleSize: Note: the decoder will try to fulfill this request, but the resulting bitmap may have different dimensions that precisely what has been requested. Also, powers of 2 are often faster/easier for the decoder to honor. How should I decode bitmaps from the SD card to get a bitmap of the exact size I need while consuming as little memory as possible to decode it?

• Thumbnails from HTML pages created and used automatically in web application

  - by Jesper Rønn-Jensen

  I am working on a Ruby on Rails app that visualizes product trees. The tree is built of nodes an everything is rendered in HTML/CSS3. Some of the products make several hundred SQL queries as the tree builds up (up to 800 queries on the biggest tree). I'd like to have small thumbnails of each tree to present it on an index page. So rendering each tree once again and modifying CSS to make a tiny representation is an option. But i think it's probably easier to generate thumbnails, crop, cache, and show these on the index page. Any ideas on how to do this? Any links/articles/blog posts that could help me?

• Datamodel for a MVC learning project

  - by Dofs

  Hi, I am trying to learn Microsoft MVC 2, and have in that case found a small project I wanted to deploy it on. My idea was to simulate a restaurant where you can order a table. Basics: A user can only reserve a full table, so I don't have the trouble of merging people on different tables. A person can order a table for a certain amount of hours. My question was how I could make the data model the smartest way. I thought of just having a my database like this: Table { Id, TableName } Reservations { Id TableId ReservedFrom ReservedTo UserId } User { UserId UserName ... } By doing it this way I would have to program a lot of the logic in e.g. the business layer, to support which tables are occupied at what time, instead of having the data model handle it. Therefore do you guys have a better way to do this?

• How to execute a command from with in MSI?

  - by okhalid

  Hi, I have a installation setup with works like this: /exec.exe /some-command This whole setup is located on a shared disk to which my target machine have access to. All i want is to create a small MSI wrapper that basically executes the above command. I don't need to any other fancy things? I looked up on the web; there are tools that create MSI for you but they generate huge amount of other things with them as well. My need is very simple and straight forward. It would be great if some could help me with this issue. Thanks, Omer
