• Adding on touch event to images inside gridview

  - by Steve

  I have a gridview where each item has a image and a textview (an app), i added the onItemClick to the gridview in order to launch the app, i also removed the orange selection and made selector in xml so when pressed the text would change to grey and on release it would return to white. My problem is that i need the image to apply an alpha value when pressed and restore the previous alpha on release i tested a lot of ways and none did worked correctly. I came close with the updated answer from the autor of the question: How to set alpha value for drawable in a StateListDrawable?, but some how the state pressed never gets called, i don´t know if this is because i am using the onitemClick to launch the app or not. Also i since i can´t define the alpha on imageview xml i don´t know what else to do Any help will be appreciated

• How could i evaluate this to a code.?

  - by WM

  There is a medieval puzzle about an old woman and a basket of eggs. On her way to market, a horseman knocks down the old woman and all the eggs are broken. The horseman will pay for the eggs, but the woman does not remember the exact number she had, only that when she took the eggs in pair, there was one left over; similarly, there was one left over when she took them three or five at a time. When she took them seven at a time, however, none were left. Write an application that can determine the smallest number of eggs the woman could have had.

• How do I determine the cause of Qt's "*** is not a valid Qt plugin" error?

  - by chadjoan

  When I print the value of errorString from my QPluginLoader object, I get this: The file 'C:/pyprojects/test/qsqlpsqld4.dll' is not a valid Qt plugin. I would like to avoid some days worth of doing the time consuming "guess-and-check" methodology that my current internet searches reveal (so far none of them seem relevant anyways). Is there a way for me to get the Qt library itself to tell me why it is refusing to load this plugin? I don't want to guess; I want to know. Context: I am on Windows 7 running Qt 4.8.5 (32-bit, MinGW) and the qsqlpsqld4.dll file is also 32-bit and compiled with MinGW. I am using PySide to interact with Qt.

• How to export changed files in dependency project when create updates? (TortoiseSVN + VisualSVN)

  - by Relax

  I have a project with it depends on another project Core, i use svn:external to maintain the dependency. when i go to create an update of my project, i export those changed files of two tags of my project, but the changed files in Core won't be exported. For example, my project 2.0 depends on Core 1.0, where 3.0 depends on Core 2.0, then i create an update, changed files of my project 3.0 will all be exported, but none of those in Core 2.0 This can be done thru a two-steps process, first export changed files of the project 3.0, then the Core 2.0, it is ok if i can remember it everytime when i create an update, but in case i forget someday, the broken update will most probably cause a crash. I wonder, is there a way to cover this situation in TortoiseSVN, will let me do it in one operation?

• iframe problem using javascript

  - by Arjun Singh

  Does anyone know how to get the HTML out of an IFRAME? I have tried several different ways: document.getElementById('iframe01').contentDocument.body.innerHTML, document.frames['iframe01'].document.body.innerHTML, document.getElementById('iframe01').contentWindow.document.body.innerHTML, etc but none of them worked. I believe the reason they're not working is that the content of my iframe doesn't have a body tag (I'm loading XML). Any other way to get all the contents of the iframe? I am open to jQuery too. This: document.getElementById('iframe01').contentWindow.document.body.innerHTML works fine in the IE, but this: document.getElementById('iframe01').contentDocument.body.innerHTML does not work for FF.

• Mongoose Not Creating Indexes

  - by wintzer

  I have been trying all afternoon to get my node.js application to create MongoDB indexes properly. I am using the Mongoose ODM and in my schema definition below I have the username field set to a unique index. The collection and document all get created properly, it's just the indexes that aren't working. All the documentation says that the ensureIndex command should be run at startup to create any indexes, but none are being made. I'm using MongoLab for hosting if that matters. I have also repeatedly dropped the collection. Please tell me what I'm doing wrong. var schemaUser = new mongoose.Schema({ username: {type: String, index: { unique: true }, required: true}, hash: String, created: {type: Date, default: Date.now} }, { collection:'Users' }); var User = mongoose.model('Users', schemaUser); var newUser = new Users({username:'wintzer'}) newUser.save(function(err) { if (err) console.log(err); });

• Base form controls not visible in child form

  - by Kildareflare

  Hello I'm using C#.Net and have a base form that is inherited by several forms. Until yesterday, when the child (derived) form was opened in the designer the base forms controls would be displayed and shown as locked. Now, however the form is simply blank. None of the base forms controls are visible in the designer. Everything compiles, builds and runs OK. Has anyone else seen this? I've tried placing a call to the base forms InitializeComponent method in the derived forms OnLoad method but to no avail.

• ANY material writen in/for DELPHI around the graphics topic?

  - by José Eduardo

  Does anyone knows ANY material writen in/for DELPHI around the graphics topic? Planning to build a software for medical imaging processing . Thinking in 3D UI to absorve the power of nvidias GTX graphics card, and some real-time 2D processing integrated with high-end scanners. Please dont take this as a "rant" but, we have zillions of C++ books writen about that kind of topic and nothing for pascal/delphi. If you have some experience could you comment about that? Is it better to learn c++, to have access to that material? Can i go with delphi? I have experience with delphi, but none with graphics... And i have a deadline... Thanks.

• How to save a complete webpage using the built-in webbrowser in c#

  - by Mike

  Overall I am trying to write out a webpage to PDF. There is a web service that I can use to convert a file to pdf. So what I am trying to do is save out a webpage from the WebBrowser winforms control. I have already tried writing it out the document stream but that just gives me the html of the page and not the images that are used with it. Another way that I looked into, but have not been successful with, is trying to create an image of the WebBrowser document. I found some examples on the web that utilize the DrawToBitmap function but none of them have worked for me. Any assistance would be grateful.

• Unique visitor counting in ASP.NET MVC

  - by Max

  I'd like to do visitor tracking similar to how stackoverflow does it.. By reading through numerous posts, I've figured out some details already: Count only 1 IP hit per 15 minutes (if anonymous) Count only 1 unique user-Login (per day?) Now that leaves the question of the real implementation.. Should I log the two factors live into a table (and increase count) | IP | timestamp | pageurl | Or do the counting AFTERWARDS (e.g. using IIS log files - which don't include the user, right? I know there're some similar posts outside, but NONE really has a great solution in my opinion yet..

• regular expression not behaving as expected - Python

  - by philippe

  I have the following function which is supposed to read a .html file and search for <input> tags, and inject a <input type='hidden' > tag into the string to be shown into the page. However, that condition is never met:( e.g the if statement is never executed. ) What's wrong with my regex? def print_choose( params, name ): filename = path + name f = open( filename, 'r' ) records = f.readlines() print "Content-Type: text/html" print page = "" flag = True for record in records: if re.match( '<input*', str(record) ) != None: print record page += record page += "<input type='hidden' name='pagename' value='psychology' />" else: page += record print page Thank you

• Trouble converting string/character to byte in lisp

  - by WanderingPhd

  I've some data that I'm reading in using read-line and I want to convert it into a byte-array. babel:string-to-octet works for the most part except when the character\byte is larger (above 200) in which case it returns two numbers. As an example, if the character is ú using babel:string-to-octet returns (195 185) instead of 250 which is what I'm looking for. I tried a number of encodings in babel but none of them seem to work. If I use read-byte or read-sequence it does read in 250. But for reasons of backward compatibility, I'm left with using read-line and I would like to know if there is something I'm missing when using babel:string-to-octet to convert ú to 250. I'm using ccl 1.8 btw.

• Drupal, Lightbox2: how can I disable the autoloading of css and javascript on triggering ?

  - by Patrick

  is there any way to disable the tag in the lightbox modal in drupal ? I've just realized it loads again all javascripts and css files of my page, and it is quite annoying, since it is not even an iFrame.. it is modal version.. and I would like to re-use what I've already loaded in my page for it. See pictures: http://dl.dropbox.com/u/72686/lightbox1.png http://dl.dropbox.com/u/72686/lightbox2.png I guess this code is wrong. I should load the node differently: " rel="lightmodal" class="LightLink" style="display:none;" title="" thanks

• WF - Creating a selective list

  - by Michael Bendtsen

  I have a stupid question. I have created a workflow Designer host where I publish my own activities. I also have a property grid which only displays the properties decorated with a special attribute. This designer is going to be used by none IT staff. What I want is that on an activity the user can select a property value from a list. I know I just could create an Enum but I would like it to be dynamic. I.e. all events on a specific interface (extracted using reflection). Is this at all possible or am I stuck with enums?

• Jquery/CSS help needed to make fallback for IE and older browsers

  - by matt_50

  Wondering if any of you can help me: I've made a signup modal that uses a CSS transform to switch between two methods of signing up. I've decided to try a 'card flip' type effect. Have a look at this JSfiddle in any browser that supports CSS 3D transforms - click the 'old fashioned way' text to 'flip' the modal (simplified for demo purposes): http://jsfiddle.net/voodoo6/cnTMz/8/ Then take a look in IE8/9 - as the 'back' is taller than the front and IE does;t support 'backface-visibility: hidden;' the reverse can be seen below the front. I've been trying to use JQuery and conditional CSS to 'display:none' the 'back' on load in IE (and older browsers), then add a 'display:block;' class to show it on click, problem is, I'm a JQuery beginner and have been struggling to get it to work! Not even sure if this is the best approach? Can anybody suggest an approach that would get this working in less-capable browsers? Thanks for any advice..

• Highlight anchor element

  I have the following three items displayed side by side: <div class="page-header"> <h1 style="line-height:0">Title</h1> <ul style="float: right; list-style-type: none;"> <li><a href="http://test1.com">T1</a></li> <li><a href="http://test2.com">T2</a></li> <li><a href="#">T3</a></li> </ul> </div> I want to highlight the item once the user clicked on it (eg. T1). Something similar to how stackoverflow has the blocks like Questions, Tags, Users etc.

• T4MVC and Ajax method with parameter

  - by Tom

  I am trying to apply T4MVC to my project. Say, I have an ajax search box, it calls Home/SearchQuery action which takes in a string q as parameter. How do I write that line in T4MVC? From Ajax.BeginForm("SearchQuery", "Home", ....

• Need a good website URL to test against

  - by Zombies

  I need a URL to just test basic http connectivity. It needs to be consistent and: Always be up Never change drastically due to IP or user agent. (IE: 301 Location redirect/ huge difference in content... minor would be tolerable) The URL itself has a consistent content-length. (IE: it doesn't vary from by 2kb at most, ever) A few examples, yet none match all 3 criteria: One example of always up: www.google.com (yet it 301 redirects based on IP location). Another good one is http://www.google.com/webhp?hl=en. but the problem there is that based on a given holiday, the content-length can really vary.

• Magento - How can I move the Navigation Block to be in the right column?

  - by Hank

  I've been editing Magento's default CSS to change the look and have come to a point where I want to move around some content blocks. I've killed off the left column through CSS .col-left { display: none; } And then increased the width of the main content part to create a 'two column layout'. What I want to do now is move the navigation for the categories into the right column. I just have no idea how... How do I move content blocks around in Magento? :/

• matplotlib plot window won't appear

  - by user1518837

  I'm using Python 2.7.3 in 64-bit. I installed pandas as well as matplotlib 1.1.1, both for 64-bit. Right now, none of my plots are showing. After attempting to plot from several different dataframes, I gave up in frustration and tried the following first example from http://pandas.pydata.org/pandas-docs/dev/visualization.html: INPUT: import matplotlib.pyplot as plt ts = Series(randn(1000), index=date_range ('1/1/2000', periods=1000)) ts = ts.cumsum() ts.plot() pylab.show() OUTPUT: Axes(0.125,0.1;0.775x0.8) And no plot window appeared. Other StackOverflow threads I've read suggested I might be missing DLLs. Any suggestions?

• How to design model for multi-tiered data?

  - by Chris

  Say I have three types of object: Area, Subarea and Topic. I want to be able to display an Area, which is just a list of Subareas and the Topics contained in those Subareas. I never want to be able to display Subareas separately - they're just for breaking up the Topics. Topics can, however, appear in multiple Areas (but probably under the same Subarea). How would I design a model for this? I could use ForeignKey from Topic to Subarea and from Subarea to Area, but it seems unnecessarily complex given that I never want to interact with subareas themselves. Also, none of these objects are ever altered or added to by the user. They're just for me to represent information. Maybe there is a better way to represent it all?

• Precision problems of real numbers in Fortran

  - by saladoil

  I've been trying to use Fortran for my research project, with the GNU Fortran compiler (gfortran), latest version, but I've been encountering some problems in the way it processes real numbers. If you have for example the code: program test implicit none real :: y = 23.234, z z = y * 100000 write(*,*) y, z end program You'll get as output: 23.23999 2323400.0. I find this really strange. Can someone tell me what's exactly happening here? Looking at z I can see that y does retain its precision, so for calculations that shouldn't be a problem I suppose. But why is the output of y not exactly the same as the value that I've specified, and what can I do to make it exactly the same?

• Image animation stops on minimizing and restoring

  - by lc

  I have a .NET WinForms application with an animated GIF in a PictureBox. It's a loading animation, shown while a BackgroundWorker does some processing in another thread. I load the image by setting the Image property and it animates on its own. All is fine until I minimize and restore the application. At which point, the image stops animating and just displays whatever frame it was last on. Note that: The background thread still runs fine and none of the "business" of the application is affected. Subsequently-displayed animated GIFs do work fine (unless the application is minimized again). Does anyone know what causes this problem? Any workarounds?

• Windows Service Fails on Launch

  - by Jeff

  I'm trying to write a windows service. It installs fine, but fails when I run it with the following exception. I've searched for the string "MyNewProgramService", but I can't find any conversions that would throw this error. I've also added try/catch blocks to a bunch of code with custom exception handling without finding where this exception is occuring. I'm thinking it's somewhere in the auto-generated configuartion/setup code. Any ideas?
