• Multiple GET arguments

  - by AJ Ravindiran

  Hello, I've been working with PHP lately, and I came across something I couldn't solve. So basically, I have a form: <form method="get"> <fieldset class="display-options" style="float: left"> Search by name or ip: <input type="text" name="key" value="" />&nbsp; <input type="submit" class="button2" value="Search" /> </fieldset> </form> The problem is, I currently already have a argument: http://example.com/logs.php?type=admin&page=1 How would i pass the given form argument with the already existing arguments? Like so: http://example.com/logs.php?type=admin&page=1&key=name Thanks in advance, AJ.

• Octave: Multiple submatrices from a matrix

  - by fbrereto

  I have a large matrix from which I would like to gather a collection of submatrices. If my matrix is NxN and the submatrix size is MxM, I want to collect I=(N - M + 1)^2 submatrices. In other words I want one MxM submatrix for each element in the original matrix that can be in the top-left corner of such a matrix. Here's the code I have: for y = 1:I for x = 1:I index = (y - 1) * I + x; block_set(index) = big_mat(x:x+M-1, y:y+M-1) endfor endfor The output if a) wrong, and b) implying there is something in the big_mat(x:x+M-1, y:y+M-1) expression that can get me what I want without needing the two for loops. Any help would be much appreciated

• Best practices for TDD BDD with code that uses external services / api

  - by adam

  I'm using a twitter gem which basically accesses twitter and lets me grab tweets, timeline etc. Its really good but I have a lot of my code that uses the stuff it returns and I need to test it. The things the gem returns aren't exactly simple strings, there pretty complex objects (scary as well) so im left scratching my head. So basically I'm looking for an answer, book, blog, open-source project that can show me the rights and wrongs of testing around external services. answers that are either not language centric or ruby/rails centric would most greatly be appreciated.

• Using TortoiseHg’s Repository explorer

  - by krebstar

  I posted this question on superuser.com but I wasn't sure if it was appropriate there.. Anyway: Hi, I'm coming from a TortoiseSVN background and decided to give TortoiseHg a try.. One thing I got really used to with TortoiseSVN was the SVN Repo-Explorer, which worked quite similarly to Windows Explorer.. However, when I tried to use TortoiseHg's Repository Explorer, what I got was something else, it was more like TortoiseSVN's Show Log. It showed me what the recent commits were and what files were changed and even had nifty graphs.. However, I'm still left wanting for TortoiseSVN's Repo-Explorer.. Does TortoiseHg have anything like this? How am I supposed to poke around the Repository if I can only view changed stuff? Thanks, kreb

• How to stop flash content shine-through JQuery UI Dialog in FF Windows

  - by DEfusion

  I'm using the jQuery UI dialog box, in IE & FF on Windows I'm getting underlying flash content shining through the dialog box. I resolved this on IE by enabling the bgiframe option on the jQuery dialog window and changing the bgiframe script to apply to any windows browsers, however I'm still getting the shine-through on FF. Note that I can't know exactly where the flash content will be showing as it is usually flash widgets that users have added to pages, although I have thought about hiding the flash content temporarily while displaying the dialog box - is this the only option left to me?

• Displaying images in a console application?!

  - by Stefan Kendall

  I have a console application which screen scrapes some data, and now I need to do image comparisons. If the images are different, I want to show the images to the user. What's the best way to display two images during the execution of a console application? I'm assuming I would use some sort of inter-process communication to send information back and forth, but I'm not sure how exactly I would go about doing that in a good fashion. Also, I'd rather NOT store the images to files if possible. There's no reason to persist the data, and if the console application terminates unexpectedly, it's better if I don't have any dirt left on the file system. Does anyone have any thoughts on how best to accomplish this?

• Take screenshot of DirectX full-screen application

  - by iconiK

  This boggles me. DirectX bypasses everything and talks directly to the device driver, thus GDI and other usual methods won't work - unless Aero is disabled (or unavailable), all that appears is a black rectangle at the top left of the screen. I have tried what other have suggested on several forums, using DirectX to get the back buffer and save it, but I get the same result: device-GetFrontBufferData(0, surface); D3DXSaveSurfaceToFile("fileName", D3DXIFF_BMP, surface, NULL, NULL); Is there any way to get a screenshot of another full-screen DirectX application when Aero is enabled?

• Default Values in XForms Input

  - by Josh

  I have an XForm that has certain fields that may often be left blank (optional street address). Is there is technique to set a default value for that field, preferably a space (I am running into weird formatting issues with CSS). The html form way of value="" doesn't work, neither does setting a default value in the XML schema. EXAMPLE: <xforms:input ref="clientaddress/streetaddress2" model="model_inventory" > <xforms:label>Street Address (Line 2)</xforms:label> Leaving this field blank results in <streetaddress2/> in the resulting xml document I want <streetaddress> </streetaddress>

• portlet 2.0 (jsr286) development with spring

  - by Patrick Cornelissen

  Hi! We are discussing whether it's a good idea to switch from plain portlet development on a liferay installation to spring webmvc portlet based development. We're starting the development of some portlets soon, so now is the time. But the problem I see is that we'd like to use some of the portlet 2.0 features, which won't work with versions older than spring 3.0. (Right?) Has anyone insight, if it's worth the waiting? (When is 3.0 scheduled anyway?) Is the current milestone stable enough? Our first real release will be in the last quarter of the year, so the springsource guys have some time left to get a final out of the door... ;-) Any ideas?

• Putting Images Inside a BUTTON Element (HTML & CSS)

  - by Jimbo

  I have a simple button (as shown below) on which I need to display two pictures, one on either side of the button text. Im battling to create the CSS that will work in both Firefox and Internet Explorer! (the button images are coming from a JQuery UI skin file) CSS button div{ width:16px; height:16px; background-image: url(images/ui-icons_d19405_256x240.png); } button div.leftImage{ background-position: -96px -112px; float: left; } button div.rightImage{ background-position: -64px -16px; float: right; } HTML <button><div class="leftPic"></div><span>Button Text</span><div class="rightPic"></div></button>

• 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?

• ScrollBars are not visible after changing positions of controls inside a Canvas

  - by akjoshi

  Hi, I created a custom canvas control inheriting from WPF Canvas. I am using it like this in main window - <ScrollViewer HorizontalScrollBarVisibility="Auto" VerticalScrollBarVisibility="Auto"> <RTD:RTDesignerCanvas Margin="5" Background="White" x:Name="canvas1" Focusable="True" AllowDrop="True"> </RTD:RTDesignerCanvas> </ScrollViewer> Everyhting works fine but when I try to set the position of controls inside it like this Canvas.SetTop(item, 200); scrollbars are not visible and control is hiddedn down somewhere. Intrestingly, if I add another control to it scroll bars are visible and I can scroll downwards to see the previous control. I tried to use base.InvalidateVisual(); base.UpdateLayout(); base.InvalidateArrange(); after changing items Top or Left but nothing happens; Am I missing something or this happens due to some bug?

• Android View.onDraw() always has a clean Canvas

  - by CaseyB

  I am trying to draw an animation. To do so I have extended View and overridden the onDraw() method. What I would expect is that each time onDraw() is called the canvas would be in teh state that I left it in and I could choose to clear it or just draw over parts of it (This is how it worked when I used a SurfaceView) but each time the canvas comes back already cleared. Is there a way that I can not have it cleared? Or maybe save the previous state into a Bitmap so I can just draw that Bitmap and then draw over top of it?

• Extract item in a list if Contains returns true

  - by Matt

  I have two lists A and B, at the beginning of my program, they are both filled with information from a database (List A = List B). My program runs, List A is used and modified, List B is left alone. After a while I reload List B with new information from the database, and then do a check with that against List A. foreach (CPlayer player in ListA) if (ListB.Contains(player)) ----- Firstly, the object player is created from a class, its main identifier is player.Name. If the Name is the same, but the other variables are different, would the .Contains still return true? Class CPlayer( public CPlayer (string name) _Name = name At the ---- I need to use the item from ListB that causes the .Contains to return true, how do I do that?

• hierarchical clustering with gene expression matrix in python

  - by user248237

  how can I do a hierarchical clustering (in this case for gene expression data) in Python in a way that shows the matrix of gene expression values along with the dendrogram? What I mean is like the example here: http://www.mathworks.cn/access/helpdesk/help/toolbox/bioinfo/ug/a1060813239b1.html shown after bullet point 6 (Figure 1), where the dendrogram is plotted to the left of the gene expression matrix, where the rows have been reordered to reflect the clustering. How can I do this in Python using numpy/scipy or other tools? Also, is it computationally practical to do this with a matrix of about 11,000 genes, using euclidean distance as a metric? thanks.

• Image Drawing on UIView

  - by user1180261

  I'm trying to create an application where I can draw a lot of pictures at a specific point (determined for each image) on one view. I have a coordinates where I need draw a picture, width and height of it For example: I have 2 billion jpeg's images. for each images I have a specific origin point and size. In 1 second I need draw on view 20-50 images in specific point. I have already tryid solve that in the next way: UIGraphicsBeginImageContextWithOptions(self.previewScreen.bounds.size, YES, 0); [self.previewScreen.image drawAtPoint:CGPointMake(0, 0)]; [image drawAtPoint:CGPointMake(nRect.left, nRect.top)]; UIImage *imagew = UIGraphicsGetImageFromCurrentImageContext(); UIGraphicsEndImageContext(); [self.previewScreen setImage:imagew]; but in this solution I have a very big latency with displaying images and big CPU usage WBR Maxim Tartachnik

• Control within ascx is null when ascx is added from codebehind

  - by Snoop Dogg

  I am having difficulties how to construct my question, but if I have to put it simply the situation is that I have categories of products. I have an aspx with a repeater on the left that lists the categories. And I want the products to be listed on the right. Category number is variable so I made an ascx with a DataList in it. When I try to do foreach category, ascx = new ascx(); then the DataList within this ascx control is null. ps: what I want to do is to preload all the products (thre is not much) and hide the divs and fadein fadeout them using jQuery when a category div is clicked. rightnow it is using jQuery.load(); and I don't like how the images load, cuz they download from top to bottom. Progressive gifs alsdo not an option. site demo is here http://techlipse.net/test/ledart Thanks a lot in advance...

• Asp.Net 3.5 Routing to Webservice?

  - by Maushu

  I was looking for a way to route http://www.example.com/WebService.asmx to http://www.example.com/service/ using only the ASP.NET 3.5 Routing framework without needing to configure the IIS server. Until now I have done what most tutorials told me, added a reference to the routing assembly, configured stuff in the web.config, added this to the Global.asax: protected void Application_Start(object sender, EventArgs e) { RouteCollection routes = RouteTable.Routes; routes.Add( "WebService", new Route("service/{*Action}", new WebServiceRouteHandler()) ); } ...created this class: public class WebServiceRouteHandler : IRouteHandler { public IHttpHandler GetHttpHandler(RequestContext requestContext) { // What now? } } ...and the problem is right there, I don't know what to do. The tutorials and guides I've read use routing for pages, not webservices. Is this even possible? Ps: The route handler is working, I can visit /service/ and it throws the NotImplementedException I left in the GetHttpHandler method.

  - by metal-gear-solid

  What is the best method to set cross-browser consistence typography (font-size and line height) for whole site using em for Fixed width {Width:970px}, centered website? I usually get design from client with multiple font size and line heights at various places in design. for some good reason i still use em without getting nested element problem and font-size inconsistencies in IE and others. then after setting how to manage and update easily ,and how to calculate ems I want to set easily manageable font sizes and I want to set Line height manually (because it can be different for various places in design. And for which things we should define line-height or for which not? How to set font-size and line-height to get consistent result. and if i'm using em for font-sizing then should i also use bottom-margin of h1, p, li etc in em? HTML {} BODY {} P {} a {} ul li a {} ul li ul li a {} p img {float:left} td,th { }

• Margin animate problem with Monitor display settings

  - by Jake

  I have an issue with an animation on a webpage. I have this div with text inside of it that I set the margin using css and when the page is loaded I use jquery to animate the div to a certain part of the page. The problem is it works with my concrete pixel settings, but if I change the properties of the monitor display settings in screen resolution(pixels), the div does not animate to the appropriate spot and it doesn't even start off at the appropriate spot from the css. Sample code: #div{ position:absolute; top:20px; left:50px } $("#div").animate({marginLeft: "250px"},2000); Is there a way to have the settings of the animation margin end at the approriate position no matter what the screen resolution is?

• What is the release date for Rakudo Star (perl6)?

  - by kbenson

  If a specific release date is not available (as I suspect it is not), can you provide resources for tracking how close it is to the desired feature set that allows release. I'm not necessarily asking for a percentage gauge, or X of Y features completed list. A list of bugs marked in whichever section of the perl RT instance that's tracking Rakudo bugs would meet my criteria, even more so if the list is dynamic (I.e. it's a list of bugs tagged in some manner, not a static list of ticket numbers). If there are only a few planned features left to be finished/tested before it's considered ready for final testing, listing those would also be sufficient.
