• Firefox XUL toolbar with javascript to IE?

  - by user325377

  Hi, I have developed a Firefox toolbar in XUL, which uses javascript to manipulate the DOM. I'd like to export this to IE. I know that IE doesn't support XUL, but wonder: (1) is there an easy way to use the existing javascript code for the IE toolbar as well? (2) is there a IE installer that easily creates all necessary registry values for creating a toolbar? I'd be grateful for any help. If anyone can point me to a sample IE toolbar code, with several buttons, drop-down menus and perhaps even a search box, that'll make things much easier as well. Thanks!

• Transposing a matrix

  - by ZaZu

  Hello, I want to transpose a matrix, its a very easy task but its not working with me : int testtranspose(testing *test,testing *test2){ int i,j; (*test2).colsmat2=(*test).rowsmat1; (*test2).rowsmat2=(*test).colsmat1 for(i=0;i<(*test).rowsmat1;i++){ for(j=0;j<(*test).colsmat1;j++){ ((*test2).mat[i][j])=((*test).mat[i][j]); } printf("\n"); } } I thought this is the correct method of doing it, but apparently for a matrix such as : 1 2 3 4 5 6 7 8 I get : 1 2 0 0 3 4 0 0 What is the problem ? Please help, Thanks !

• SVN Externals in a different SCM

  - by Sean Chambers

  At a previous workplace we used svn externals to update dependent projects when a shared component was updated. This made it easy to see anything that those changes broke, as well as update dependent projects to the latest version of a shared component automatically without any intervention. At a new workplace we are using cc.net with surround scm and I'm trying to find something similar in surround. I haven't found anything like externals, only "shared files", but unlike externals, the shared files doesn't allow you to point at a specific revision of a file for the external. I'm interested in what other people are doing in these scenarios to lean on their continuous integration and treat it more for integration than a "continuous build" server. Does anyone know of a tool or something to do "externals" behavior without using svn? I suppose having an xml registry file of which projects depend on which assemblies and if they should be using the latest version but this seems like overkill.

• How can I use gnuplot to plot data that is in an un-friendly format?

  - by Zack

  I need to graph some data that is not exactly in the most friendly format, most examples or usage puts things in a nice column/table that is very easy to parse and graph. However I have the following format (and am a bit stuck as to how to tackle this): DATE1 label_1 xx yy DATE1 label_2 xx yy DATE1 label_3 xx yy DATE2 label_2 xx yy DATE2 label_3 xx yy DATE3 label_1 xx yy DATE3 label_2 xx yy DATE3 label_3 xx yy DATE4 label_2 xx yy DATE4 label_3 xx yy ...continues *I've added the extra space between the dates for readability. **Note: under DATE2,DATE4 label_1 is missing, i.e. the data file may have labels that come and go and should represent a discontinuity in the graph. I'd like to have the X-axis use the DATEX for the labels, and then create two lines for each label (xx and yy respectively). Does anyone have any suggestions on the best way to tackle this problem?

• Customise a control in dynamics crm

  - by webturner

  I've written code that can make a phone dial a number from a function call, that's done and dusted. What I would like to achieve is adding a Dial button to each phone number field on the forms in Dynamics CRM. Eventually this could also create a new phone record fill in the basic details and show it to the user to enter notes and an outcome for the phone call, and perhaps some other workflow bits to schedule the next call. Can I put a custom control on a standard form in place of the standard control. I'm assuming it would have to be an IFrame to an asp.net page, that pulls in the record id, and the field name, looks up the number to show in a text box, and passes the number to the DialNumber function. Hey presto... I assume its not going to be that easy... Has anyone tried this before, what's the process, what are the gotchas?

• Template and Themes in WPF through Custom Xaml Files

  - by AKRamkumar

  I have an application where I give my user Widgets. Suppose my user wants to customize the layout of the widgets. For example, I have a clock that is green. In Xaml, to add an animation around the clock would be easy. How could i make it such that at runtime, my application reads a layout.xaml file. Loads it and parses all the gradients and xaml. But still be able to use my widget in there. EG <Layout> <Grid> <!-- Grid Definitions or Animations or Whatever--> <Clock/> <!-- They need to be able to simply use this and my applications needs to read this--> </Grid> </Layout>

• How do I get the sums of the digits of a large number in Haskell?

  - by Tim

  I'm a C++ Programmer trying to teach myself Haskell and it's proving to be challenging grasping the basics of using functions as a type of loop. I have a large number, 50!, and I need to add the sum of its digits. It's a relatively easy loop in C++ but I want to learn how to do it in Haskell. I've read some introductory guides and am able to get 50! with sum50fac.hs:: fac 0 = 1 fac n = n * fac n - 1 x = fac 50 main = print x Unfortunately at this point I'm not entirely sure how to approach the problem. Is it possible to write a function that adds (mod) x 10 to a value and then calls the same function again on x / 10 until x / 10 is less than 10? If that's not possible how should I approach this problem? Thanks!

• Site images don't refresh after setting expired headers on .htaccess

  - by Miguel Hernandez

  I have a site that uses a CSS sprite for all the images. I set the .htaccess file to set the expired headers to a future time as they recommend to improve site performance. However, when I updated the sprite image none of my browsers on two different computers seem to fetch the new image. I deleted the .htaccess serveral times but no luck. I am sure this must be easy as pie to fix but right now I am out of options. Here is the code inside my .htaccess file: # CONFIGURE media caching # Header unset ETag FileETag None <FilesMatch "(?i)^.*\.(ico|flv|jpg|jpeg|png|gif|js|css)$"> Header unset Last-Modified Header set Expires "Fri, 21 Dec 2012 00:00:00 GMT" Header set Cache-Control "public, no-transform" </FilesMatch> <IfModule mod_deflate.c> <FilesMatch "\.(js|css)$"> SetOutputFilter DEFLATE </FilesMatch> </IfModule> Thanks!

• Python: Dynamic attribute name generation without exec() or eval()

  - by PyNewbie27

  Hi, I'm trying to dynamically create buttons at runtime with PyQT4.7 However, this being my first python program I'm not sure how to get the functionality I want. I would like to be able to substitute a text string for an attribute name: i.e. for each in xrange(4): myname = "tab1_button%s" % each #tab1_button0, tab1_button1, tab1_button2 #self.ui.tab1_button0 = QtGui.QPushButton(self.ui.tab) <--normal code to create a named button setattr(self.ui,myname,QtGui.QPushButton(self.ui.tab)) #rewrite of line above to dynamicly generate a button #here's where I get stuck. this code isn't valid, but it shows what i want to do self.ui.gridLayout.addWidget(self.ui.%s) % myname #I need to have %s be tab1_button1, tab1_button2, etc. I know the % is for string substituion but how can I substitute the dynamically generated attribute name into that statement? I assume there's a basica language construct I'm missing that allows this. Since it's my first program, please take it easy on me ;)

• How to implement a syndication receiver? (multi-client / single server)

  - by LeonixSolutions

  I have to come up with a system architecture. A few hundred remote devices will be communicating over internet with a central server which will receive data and store it in a database. I could write my own TCP/IP based protocol use SOAP use AJAX use RSS anything else? This is currently seen as one way (telemetry, as opposed to SCADA). Would it make a difference if we make it bi-directional. There are no plans to do so, but Murphy's law makes me wary of a uni-directional solution (on the data plane; I imagine that the control plane is bi-directional in all solutions (?)). I hope that this is not too subjective. I would like a solution which is quick and easy to implement and for others to support and where the general "communications pipeline" from remote deceives to database server can be re-used as the core of future projects. I have a strong background in telecomms protocols, in C/C++ and PHP.

• What is the easiest way to remove the Silverlight TextBox mouse hover border?

  - by Edward Tanguay

  I want to display text in a Silverlight application so that the user can copy and paste it elsewhere (as one is used to doing on an HTML web site). If I use TextBlock, then the user cannot cut and paste. Therefore I use TextBox, but it has a default border on it. I can remove the border with BorderThickness="0" like this: <TextBox Grid.Column="1" BorderThickness="0" Text="{Binding ViewModelBindingStringsBlockHelp}"/> which works great: However, when the user hovers over the text box to select the text, another border appears: I've found purported solutions but they seem to require pages of XAML. I'm looking for a simple solution like this: HoverBorderThickness="0" What is an easy way to hide the hover border on a Silverlight TextBox?

• Executing certain code for every method call in C++

  - by Luís Guilherme

  I have a C++ class I want to inspect. So, I would like to all methods print their parameters and the return, just before getting out. The latter looks somewhat easy. If I do return() for everything, a macro #define return(a) cout << (a) << endl; return (a) would do it (might be wrong) if I padronize all returns to parenthesized (or whatever this may be called). If I want to take this out, just comment out the define. However, printing inputs seems more difficult. Is there a way I can do it, using C++ structures or with a workaroud hack?

• How do I branch an individual file in SVN?

  - by Michael Carman

  The subversion concept of branching appears to be focused on creating an [un]stable fork of the entire repository on which to do development. Is there a mechanism for creating branches of individual files? For a use case, think of a common header (*.h) file that has multiple platform-specific source (*.c) implementations. This type of branch is a permanent one. All of these branches would see ongoing development with occasional cross-branch merging. This is in sharp contrast to unstable development/stable release branches which generally have a finite lifespan. I do not want to branch the entire repository (cheap or not) as it would create an unreasonable amount of maintenance to continuously merge between the trunk and all the branches. At present I'm using ClearCase, which has a different concept of branching that makes this easy. I've been asked to consider transitioning to SVN but this paradigm difference is important. I'm much more concerned about being able to easily create alternate versions for individual files than about things like cutting a stable release branch.

• Quickly generate/publish RSS feeds from ASP.NET projects?

  - by jdk

  Under a timeline, therefore the salient point is "quickly" and willing to throw some $ at it too (doesn't have to be a free solution). Looking for an RSS feed generator usuable in .NET framework 2.0. Ideally it would be easy to use (inferred quick) but flexible enough to support the multiple standards (shown part way down this page). We have the business classes in .NET and want to publish RSS feeds on the ASP.NET website. Any software that's good? Doesn't have to be free. Must support .NET framework 2.0 Thanks.

• Python / Django : emulating a multidimensional layer on a MySQL database

  - by Sébastien Piquemal

  Hi, I'm working on a Django project where I need to provide a lot of different visualizations on the same data (for example average of a value for each month, for each year / for a location, etc...). I have been using an OLAP database once in college, and I thought that it would fit my needs, but it appears that it is much too heavy for what I need. Actually the volume of data is not very big, so I don't need any optimization, just a way to present different visualizations of the same data without having to write 1000 times the same code. So, to recap, I need a python library: to emulate a multidimensional database (OLAP style would be nice because I think it is quite convenient : star structure, and everything) non-intrusive, because I can't modify anything on the existing MySQL database easy-to-use, because otherwise there's no point in replacing some overhead by another.

• basic unique ModelForm field for Google App Engine

  - by Alexander Vasiljev

  I do not care about concurrency issues. It is relatively easy to build unique form field: from django import forms class UniqueUserEmailField(forms.CharField): def clean(self, value): self.check_uniqueness(super(UniqueUserEmailField, self).clean(value)) def check_uniqueness(self, value): same_user = users.User.all().filter('email', value).get() if same_user: raise forms.ValidationError('%s already_registered' % value) so one could add users on-the-fly. Editing existing user is tricky. This field would not allow to save user having other user email. At the same time it would not allow to save a user with the same email. What code do you use to put a field with uniqueness check into ModelForm?

• F# Extention Methods on Lists, IEnumberable, etc

  - by flevine100

  I have searched StackOverflow (and other sources) for this answer, but can't seem to find anything. In C#, if I had a widget definition, say: class widget { public string PrettyName() { ... do stuff here } } and I wanted to allow for easy printing of a list of Widgets, I might do this: namespace ExtensionMethods { public static PrintAll( this IEnumerable<Widget> widgets, TextWriter writer ) { foreach(var w in widgets) { writer.WriteLine( w.PrettyName() ) } } } How would I accomplish something similar with a record type and a collection (List or Seq preferrably in F#). I'd love to have a list of Widgest and be able to call a function right on the collection that did something like this. Assume (since it's F#) that the function would not be changing the state of the collection that it's attached to, but returning some new value.

• Synchronization between hibernate running locally and on a server

  - by linead

  Is there an easy way using a library to facilitate the synchronization of two hibernate instances. One running locally on a client and one running on a central server exposed via a web service. So Client tracks changes it makes, pushes them to the Server. The server ensures that the clients is not updating out of sync objects and stores the clients changes. The Client can also sync with the Server so that it can see the changes made by other clients. The idea is that the client can be run offline, without access to the server and only come online to synchronize when needed.

• Java's ThreadPoolExecutor equivalent for C#?

  - by chillitom

  Hi Guys, I used to make good use of Java's ThreadPoolExecutor class and have yet to find a good equivalent in C#. I know of ThreadPool.QueueUserWorkItem which is useful in many cases but no good if you want to control the number of threads assigned to a task or have multiple individual queues for different task types. For example I liked to use a ThreadPoolExecutor with a single thread to guarantee sequential execution of asynchronous calls.. Is there an easy way to do this in C#? Is there a non-static thread pool implementation? Thanks, T.

• Custom editor in QAbstractTableModel

  - by Martin Beckett

  Does anyone have an example of using a QWidget as an editor in a QAbstractTableModel? I have a column which when edited should create a QCombobox with the list of choices. The docs seem to suggest I need to write a QAbstractItemDelegate and a custom paint function but that seems overkill to simply pop-up a standard QCombobox in Qt::EditRole. Note - the combo box contents are the same for every row and it only needs to be shown when somebody clicks in the cell. I know this should be simple but I can't get it to work. It's easy for a QTableWidget based table - but I need it for a very large data table.

• Using read() directly into a C++ std:vector

  - by Joe

  I'm wrapping up user space linux socket functionality in some C++ for an embedded system (yes, this is probably reinventing the wheel again). I want to offer a read and write implementation using a vector. Doing the write is pretty easy, I can just pass &myvec[0] and avoid unnecessary copying. I'd like to do the same and read directly into a vector, rather than reading into a char buffer then copying all that into a newly created vector. Now, I know how much data I want to read, and I can allocate appropriately (vec.reserve). I can also read into &myvec[0], though this is probably a VERY BAD IDEA. Obviously doing this doesn't allow myvec.size to return anything sensible. Is there any way of doing this that 1) Doesn't completely feel yucky from a safety/C++ perspective and 2) Doesn't involve two copies of the data block - once from kernel to user space and once from a C char * style buffer into a C++ vector. Any thoughts collective?

• How can I dynamically inject code into event handlers in Delphi?

  - by mjustin

  For debugging / performance tests I would like to dynamically add logging code to all event handlers of components of a given type. For example, for all Dataset components located ona TDatamodule, I would like to add some code for the BeforeOpen and the AfterOpen event to store the start and end time and send a line to a logger with the elapsed time in the AfterOpen event. I would prefer to do this dynamically (no component subclassing), so that I can add this to all existing datamodules and forms with minimal effort only when needed. Iterating all components and filtering by their type is easy, but for the components which already have event handlers assigned, I need a way to store the existing event handlers, and assign a new modified event handler which first does the logging and then will invoke the original code which was already present. Is there a design pattern which can be applied, or even some example code which shows how to implement this in Delphi?

• encoding of =1 in emails

  - by Maenny

  Hi folks, I have probably a stupid problem. In a script I generate a URL with GET parameters, something like 'www.mydomain.com/index.php?item=1234'. This URL will be sent by PHP through mail() in an UTF-8 encoding (the scriptfile itself also is utf-8). Now each time I have the GET-Parameter with two numbers after the '=' the URL in the email looks like 'www.mydomain.com/index.php?item?34' with a rectangle instead of '=12'. I am sure there is an easy way to fix this? Thanks in advance, Maenny

• What's a good unit test framework for Common Lisp projects?

  - by Lorenzo V.

  I need to write a unit test suite for a project I am developing in my spare time. Being a CL newbie I was overwhelmed by the amount of choices for a CL implementation, I spent quite some time to choose one. Now I am facing exactly the same thing with unit test frameworks. A quick glance at http://www.cliki.net/test%20framework shows 20 unit test frameworks! Choice is good but for a novice like me this can be a bit confusing and given the number of frameworks it would be painful to try them all. I would like to use a framework which: Is reasonably well maintained Easy to use but with some degree of flexibility Offers some sort of integration with Emacs (or it is possible to easily integrate it with Emacs) Integration with git post-commit hooks Integration with a continous integration system (such as buildbot) What are your experiences in this field?

• Simulating a cookie-enabled browser in PHP

  - by Itamar Benzaken

  How can I open a web-page and receive its cookies using PHP? The motivation: I am trying to use feed43 to create an RSS feed from the non-RSS-enabled HighLearn website (remote learning website). I found the web-page that contains the feed contents I need to parse, however, it requires to login first. Luckily, logging in can be done via a GET request so it's as easy as fopen()ing "http://highlearn.website/login_page.asp?userID=foo&password=bar" for example. But I still need to get the cookies generated when I logged in, pass the cookies to the real client (using setcookie() maybe?) and then redirect.
