• Jquery UI Dialog Weird Behavior in Firefox - Whole screen becomes non-clickable on second overlay

  - by Dondon Vizcayno

  I have two links that show up two modal dialogs. These dialogs are static divs in the html of the page with their own ids. When I click the first link, the first dialog shows up and behaves correctly. But when I click the second link, the whole screen grays out and everything becomes unclickable, including the second dialog. It happens also the other way around, clicking the second link, and then the first link. This problems occurs only in Firefox but not in IE. Any ideas why this is happening in Firefox?

• Removing WS_BORDER and WS_CAPTION from windows styles doesn't work

  - by lordfrikk

  Hello, I created a small app in C# that removes border and caption from window, then it sets size to the user's resolution and centers it. It's a utility for me to use when I want to play games in windowed mode without being annoyed by the borders. Everything works fine with most games, but I tried to use it on a recently released game Alpha Protocol and it doesn't work. I could almost say that the game reverts my changes, but I'm not sure how to tell if that's true or not. I'm using imported API functions MoveWindow, SetWindowLong and SetWindowPos. Snippet: Win32.MoveWindow(hWnd, 0, 0, Convert.ToInt32(sizeXText.Text), Convert.ToInt32(sizeYText.Text), true); Win32.SetWindowLong(hWnd, GWL_STYLE, Win32.GetWindowLong(hWnd, GWL_STYLE) & ~WS_CAPTION & ~WS_BORDER); Win32.SetWindowPos(hWnd, 0, 0, 0, 0, SWP_NOZORDER|SWP_NOMOVE|SWP_NOSIZE|SWP_NOACTIVATE|SWP_DRAWFRAME);

• Linq to SQL EntitySet Records causing duplicate insertion

  - by Savvas Sopiadis

  In a WPF application i'm using Linq to SQL in a multi tier application. (This is an archailogy photo filing application), so every excavation has its corresponding Pictures, thus a one-to-many relationship. This relationship is correctly created by SQLMetal (which i'm using to create the POCOs). So here is the situation i 'm having trouble with: Saving changes (either of new or altered objects) is done through UnitOfWork() pattern this way: using (IUnitOfWork unitOfWork = UnitOfWork.Begin()) { //if this is a new record if (SelectedExcavation.excavation.ExcavationId == 0) { IsNewRecord = true; excavService.Add(SelectedExcavation.excavation); } //send the actual changes to the dbms unitOfWork.Commit(); } Everything works fine! BUTTTT!!! Whenever a record gets updated which has (already at least one ) corresponding Picture Record: 1) a new Excavation Record is inserted 2) the current Excavation Record gets updated 3) the previous Picture Record gets its Id changed to the newly created ExcavationId What is going on under the hood? Does Linq to SQL not handle such simple update scenarios? Thanks in advance

• The difference between the 'Local System' account and the 'Network Service' account?

  - by jmatthias

  I have written a Windows service that spawns a separate process. This process creates a COM object. If the service runs under the 'Local System' account everything works fine, but if the service runs under the 'Network Service' account, the external process starts up but it fails to create the COM object. The error returned from the COM object creation is not a standard COM error (I think it's specific to the COM object being created). So, how do I determine how the two accounts, 'Local System' and 'Network Service' differ? These built-in accounts seem very mysterious and nobody seems to know much about them.

• Linux, how to capture screen, and simulate mouse movements.

  - by 2di

  Hi All I need to capture screen (as print screen) in the way so I can access pixel color data, to do some image recognition, after that I will need to generate mouse events on the screen such as left click, drag and drop (moving mouse while button is pressed, and then release it). Once its done, image will be deleted. Note: I need to capture whole screen everything that user can see, and I need to simulate clicks outside window of my program (if it makes any difference) Spec: Linux ubuntu Language: C++ Performance is not very important,"print screen" function will be executed once every ~10 sec. Duration of the process can be up to 24 hours so method needs to be stable and memory leaks free (as usuall :) I was able to do in windows with win GDI and some windows events, but I'ev no idea how to do it in Linux. Thanks a lot

• Need help using ThemeRoller

  - by Music Magi

  Hi - I'm using DataTables to dress up a table I'm using to display XML results based on an XSL transformation. I have everything working from a technical sense (paging, sorting, filtering), but I'm trying to figure out to use a ThemeRoller theme to make it look like they have on their website. So far, I have added the following file to my project with its reference: <link type="text/css" href="css/custom-theme/jquery-ui-1.8.7.custom.css" rel="stylesheet"/> and enabled ThemeRoller themes using the following as per the DataTables website: $(document).ready(function() { $('#mainTable').dataTable( { "bJQueryUI": true, "sPaginationType": "two_button" }); }); The table gets styled, but it doesn't look right with the header rows being too wide and things being on multiple lines that should be on one line. Any indication as to what I'm doing wrong? Thanks very much in advance.

• Problem about python import with error

  - by xiao

  Hello, I have write a small python module with one class and two functions. The skeleton of the module is as following: #file name: test_module.py class TestClass: @classmethod def method1(cls, param1): #to do something pass def __init__(self, param1): #to do something ... def fun1(*params): #to do something ... def fun2(*params): #to do something ... Another py file is a small script which imports function and class from the module, as following: import sys from test_module import TestClass, fun1, fun2 def main(sys_argv): li = range(5) inst1 = TestClass(li) fun1(inst1) fun2(inst1) return if __name__ == "__main__": main(sys.argv) But when I execute the script, it is broken with following message: ./script.py: line 4: syntax error near unexpected token `(' ./script.py: line 4: `def main(sys_argv):' I am not sure what the problem is. Is it a problem with import? But when I try to import the module in ipython, everything is just ok.

• Problem w/ Paperclip, MacPorts, ImageMagick & Snow Leopard

  - by Kyle Decot

  I'm attempting to use ImageMagick along w/ Paperclip to handle the images on my rails app. The problem is whenever I try to upload an image I get the following in the terminal: [paperclip] An error was received while processing: #<Paperclip::NotIdentifiedByImageMagickError: /var/folders/go/goZ833AaFaqyvv5RnLqQmE+++TM/-Tmp-/stream20110107-6356-1xfs9j1-0.jpg is not recognized by the 'identify' command.> I have added the following to my environments/development.rb file: Paperclip.options[:command_path] = "/usr/local/bin" If I try to interact w/ ImageMagick in the terminal by using "convert" or something similar I get: dyld: Library not loaded: /opt/local/lib/libltdl.7.dylib Referenced from: /usr/local/bin/convert Reason: Incompatible library version: convert requires version 10.0.0 or later, but libltdl.7.dylib provides version 9.0.0 Trace/BPT trap I've already tried updating everything w/ port but the problem still persists. Does anyone have any ideas or suggestions?

• Finding matches between multiple JavaScript Arrays

  - by Chris Barr

  I have multiple arrays with string values and I want to compare them and only keep the matching results that are identical between ALL of them. Given this example code: var arr1 = ['apple', 'orange', 'banana', 'pear', 'fish', 'pancake', 'taco', 'pizza']; var arr2 = ['taco', 'fish', 'apple', 'pizza']; var arr3 = ['banana', 'pizza', 'fish', 'apple']; I would like to to produce the following array that contains matches from all given arrays: ['apple', 'fish', 'pizza'] I know I can combine all the arrays with var newArr = arr1.concat(arr2, arr3); but that just give me an array with everything, plus the duplicates. Can this be done easily without needing the overhead of libraries such as underscore.js? (Great, and now i'm hungry too!) EDIT I suppose I should mention that there could be an unknown amount of arrays, I was just using 3 as an example.

• glReadPixels and save to image

  - by Julius Petraška

  I have app, where user drags and drops image, and it is being redrawn with OpenGL for some aviable processing. Everything works. And when user wants to save his image it works like that: glReadPixels -> NSBitmapImageRep -> NSData -> Write to file This works too. Almost. With some images it is not working as it should work. For example: .png when I open and save this image: I get: And if I open and save this image: I get: .jpg If I open and save: I get: And when I open and save: I get: So sometimes images saves badly. Why is it happening?

• why do we all learn and study java or .net or why java or .net are popular?

  - by tadeze

  My question to be clear is why do we all need to learn java or .net(C#) , still java or .net are more popular than delphi or c++ and even there are lot of resource,articles or books compared to c++ or delphi about java and .net. However, I heard majority, if I am right about 80% of software are developed using c++ or delphi in the software industry. so, why do we bother about other languages specifically about the cosmopolitan languages such as java or .net in education as well as for job interview. Although, still I know the elegance of java and .net, their safe code execution,fully objected oriented behavior ...etc, but still according to the statics they are not preferred on software develpement as a primary language mainly because of their execution time compared to c++ or delphi. So my question are why do they choose them for jobs or educational purpose and everything else? why do we lose our time learning these language if we are forced to use the other languages in the industry?

• Where/When do C# and the .NET Framework fail to be the right tool?

  - by Nate Bross

  In my non-programming life, I always attempt to use the appropriate tool for the job, and I feel that I do the same in my programming life, but I find that I am choosing C# and .NET for almost everything. I'm finding it hard to come up with (realistic business) needs that cannot be met by .NET and C#. Obviously embedded systems might require something less bloated than the .NET Micro Framework, but I'm really looking for line of business type situations where .NET is not the best tool. I'm primarly a C# and .NET guy since its what I'm the most comfertable in, but I know a fair amount of C++, php, VB, PowerShell, batch files, and Java, as well as being versed in the web technologes (JavaScript, HTML, and CSS). But I'm open minded about it my skill set and I'm looking for cases where C# and .NET are not the right tool for the job. I choose .NET and C# because I'm comfortable with it, but I'm looking for cases where it isn't appropriate.

• Connect to https:// webservice in asp.net app

  - by webnoob

  Hi All, I have an ASP.NET website that is contacting a webservice. Everything works fine connecting via http but when I try https:// it can't connect. I don't seem to get any error from the website and the webservice logs show nothing, meaning nothing has connected to it. I can connect to my https:// webservice from a site like soapclient.com and request information, so the webservice and ports are working. Is there anything special I should be doing in order to connect to a https:// webservice over a normal http:// one in .NET? All I am doing at the moment is changing the URL it is connecting to to my secure one instead. I am using ASP.NET 2, IIS7 Thanks in advance.

• Microsoft JScript runtime error: Object required

  - by Nani

  I wrote a simple javascript function for validating to fields in a aspx page function validate() { if (document.getElementById("<%=tbName.ClientID%>").value=="") { alert("Name Feild can not be blank"); document.getElementById("<%=tbName.ClientID%>").focus(); return false; } if (document.getElementById("<%=ddlBranch.ClientID%>").value=="SelectBranch") { alert("Branch Should Be Selected"); document.getElementById("<%=ddlBranch.ClientID%>").focus(); return false; } } Everything worked fine. Later I linked it to aspx page like a external js file. Now its giving error "Microsoft JScript runtime error: Object required". I'm unable to know where I went wrong.

• How to use pom.xml/Maven to initialize a local thoughtsite (App Engine sample) project in Eclipse?

  - by ovr

  This sample app ("thoughtsite") for App Engine contains a pom.xml in its trunk: http://code.google.com/p/thoughtsite/source/browse/#svn/trunk But I don't know what command to run in Maven to set up the project locally. (The README doesn't mention anything about Maven.) I tried to just import the project code directly into Eclipse but it doesn't look like it's in an appropriate format for a direct import. So I assume I need to do something with Maven to get it set up correctly. I haven't really used Maven before so I'm not sure what command I would need to run to set everything up. The pom.xml seems like it downloads a bunch of dependencies for the project like the Spring jar files which I don't see anywhere else in the svn repository.

• Why doesn't this html/css work in ie?

  - by hhj

  I am just trying to center a div on the page. It works in chrome but in i.e. the div is still on the left: <html> <head></head> <body> <div id="container" style="margin:0 auto; width:200px;"> test </div> </body> </html> Everything I've read has said that to center a block element, simply add margin:0 auto and specify a width, so I don't know why this isn't working. I am testing on IE 7.0.5730

• flex strange problem with namespaces.

  - by pfunc

  I'm trying to understand what is going on with my namespaces since I upgraded to flash builder 4. xmlns:mx="http://www.adobe.com/2006/mxml" in the application and in the stylesheets: @namespace mx "library://ns.adobe.com/flex/mx"; Everything seems to be recognized correctly, however, I get a warning that says "borderThickness" is only supported by the halo theme (which I thought was in the mx theme). Now, when I try xmlns:s="library://ns.adobe.com/flex/mx" then it doesn;t recognize anything. Is there something I might be doing wrong here or confusing?

• Can't find a Wordpress image/photo gallery plugin

  - by mgroves

  I've been looking at Wordpress plugins for photo galleries (so maybe this is for superuser.com), and I've been very frustrated so far. It seems like what I'd like to do would be a very common use case: Admin: Be able to upload multiple pictures (at a time) Admin: Be able to assign a "gallery" to those pictures as I upload them User: Be able to go to a page with a (paged) list of all galleries User: Be able to click on gallery and view the images (again, probably paged) in that gallery User: Be able to click on an image to get larger/largest sizes User: Be able to leave comments on individual pictures (this is a "nice to have") The images/galleries could be totally independent of posts/pages, but it would be nice to be able to embed those images/galleries into posts/pages when necessary. Is there anything out there like this that I'm missing? I've tried a handful of plugins and none of them seem to be for a use case anywhere close to what I'm looking for. One of the reasons I'm trying to use Wordpress is to reduce time spent coding everything I want.

• Rails: Generated tokens missing occasionally

  - by Vincent Chan

  We generate an unique token for each user and store it on database. Everything is working fine in the local environment. However, after we upload the codes to the production server on Engine Yard, things become weird. We tried to register an account right after the deploy. It is working fine and we can see the token in the db. But after that, when we register new accounts, we cannot see any tokens. We only have NULL in the db. Not sure what caused this problem because we can't re-produce this in the local machine. Thanks for your help.

• Rotate a feature Image in Open Layers

  - by Ozaki

  I have an open layers map. It adds and removes my "imageFeature" every 10secs or so. I have a JSON feed that gives me the rotation that I need, I have a request to get that rotation and set it as a variable of rotationv. Everything works but the fact when the image is recreated it does not update the rotation. My code is as follows: JSON request: var rotationv = (function () { rotationv = null; $.ajax({ 'async': false, 'global': true, 'url': urldefault, 'dataType': "json", 'success': function (data) { rotationv = data.rotation; } }); return rotationv })(); Creating image feature: imageFeature = new OpenLayers.Feature.Vector( new OpenLayers.Geometry.Point(mylon, mylat), { rotation: rotationv } ); The image is set in the styling elsewhere. Why does this not rotate my image?

• How do negated patterns work in .gitignore?

  - by chrisperkins

  I am attempting to use a .gitignore file with negated patterns (lines starting with !), but it's not working the way I expect. As a minimal example, I have the folllowing directory structure: C:/gittest -- .gitignore -- aaa/ -- bbb/ -- file.txt -- ccc/ -- otherfile.txt and in my gitignore file, I have this: aaa/ !aaa/ccc/ My understanding (based on this: http://ftp.sunet.se/pub//Linux/kernel.org/software/scm/git/docs/gitignore.html) is that the file aaa/ccc/otherfile.txt should not be ignored, but in fact git is ignoring everything under aaa. Am I misunderstanding this sentence: "An optional prefix ! which negates the pattern; any matching file excluded by a previous pattern will become included again."? BTW, this is on Windows with msysgit 1.7.0.2.

• what does the @ symbol mean in ls -l directory listing?

  - by Andrew Arrow

  When I run ls -l on my mac I see two .yml files: -rw-r--r-- 1 aa staff 6 Apr 15 05:50 s1.yml -rw-r--r--@ 1 aa staff 362 Apr 15 05:49 s3.yml same owner, same permissions but one has a @ at the end of the permisions. The one with the @ shows up in my editor, the one without does not. So there must be some significance. How can I turn on the @ for the file without it? I selected the files in the finder and did get info and everything looks identical between the two files.

• Is there a tool for detecting Visual Studio projects with duplicate GUIDs?

  - by sharptooth

  When creating new Visual Studio C++ projects there're two ways: either run the wizard and then painfully change all the necessary settings in the project or just copy and existing project, rename everything there and add files into it. The second variant is great except that the .vcproj file stores a project GUID. This GUID is used to track project dependencies and the startup project when two or more projects are in one solution. If any two projects in one solution have identical GUIDs problems can arise - dependencies are lost and the startup prject is reset on next solution reload. Clearly there's a need for a tool that would scan the filesystem subtree and detect projects with identical GUIDs here. Before I start writing one ... is there a ready tool for that?

• jQuery Date Picker where text input is read only

  - by Rowan Parker

  Hi all, I want to use the Jquery datepicker. I've got it setup using an the alt field option. I'm displaying Y-M-D in the text field, but submitting Y-M-D. Everything works fine so far, sending the correct data, etc. However I want to stop the user from being able to manually type a date. I add originally set the INPUT field to disabled, which worked in every browser except IE. In IE it would popup the date picker but then not close after clicking a date. Does anyone know the best way to do this?
