  • How can I bind dynamic data to DataGridTemplateColumn in code?

    - by TuomoT
    I'm using DataGrid from CodePlex. I have objects (ICustomTypeDescriptor) that have properties 'name' 'description' 'c' 'd' and so on (the names are dynamic, and so is the value) and they have information behind them. I have templates for different types. And if I have to list the properties of a single element I can just bind to the values in xaml and use datatemplateselector (in datagridtemplatecolumn) which will pick the correct template. However, when I'm listing several of the elements, how can I use the selectors and the templates? How do I get the correct property bound to the template (two-way)? When ignoring the need for different templates, using DataGridTextColumn with bindings is very simple (and works, see example below), is there any way to use similar approach with the DataGridTemplateColumn? foreach (String propertyName in listOfPropertyNames) { DataGridTextColumn textColumn = new DataGridTextColumn() { Header = propertyName, Binding = new Binding() { Path = new PropertyPath(propertyName) } }; DataGrid.Columns.Add(textColumn); }

  • Does Google provide any Android tutorials that teach how to implement a Service?

    - by Bub
    I apologize in advance for the "newbie" nature of this question. Here is my predicament: I'm brand new to android and developing in general. I'm using android's SDK with eclipse Galileo. I've followed several tutorials to create different layouts. I've even learned recently how to use radio buttons and verify which ones were selected. Now I need to create a service that downloads and updates an xml file within the application. I've tried to locate a simple tutorial for services on Google's developer site but so far, so bad. If they exist could somebody point me in the right direction? On the other hand, I've been told Google's tutorials are a little out dated. Is that true? If so, are there any other tutorials that would hand-hold (and possibly over-explain) how to use a service to a true newbie for free (like google)? Any suggestions would be appreciated.

  • Save VM properties with EF code first

    - by Julien
    I thought this would be simple but can't find any good examples. public Class BookVm : ImplementsPropertyChanged { public int BookId {get;set;} private bool _favorite; public bool Favorite { get { return _favorite; } set { _favorite = value; OnPropertyChanged("Favorite"); MyDbContext.SaveChanges() // this does not work } } Then in my XAML bound to Book <CheckBox Content="Favorite" IsChecked="{Binding Favorite}" /> How and when do I call SaveChanges() on my DatabaseContext? I don't want to implement a save button. If I intercept the PropertyChange event and call SaveChanges, nothing seems to happen. My object is modified in memory but the database does not see a change. My BookVm class is created on application startup like so: foreach (var book in MyDbContext.Books) Books.Add(book); Where Books is an ObservableCollection<Book> in my MainWindowVm

  • Syntax error in SharePoint calculated column formula

    - by Jan Aagaard
    Is it possible to debug SharePoint calculated column formulas? I am trying with a really simple SharePoint calculated formula =IF([YTD]<[Budget], "OK", "Not OK"). This being a Danish installations of SharePoint I believe the fomula should look like this: =HVIS([YTD]<=[Budget]; "OK"; "Not OK") But this just leaves with the same syntax error or not supported error. I have tried all combinations of IF/HVIS, with/without the square brackets, comma/semicolon, single quotes/double quotes, but nothing works. The formula =YTD<=Budget works.

  • Easy framework for OpenGL Shaders in C/C++

    - by Nils
    I just wanted to try out some shaders on a flat image. Turns out that writing a C program, which just takes a picture as a texture and applies, let's say a gaussian blur, as a fragment shader on it is not that easy: You have to initialize OpenGL which are like 100 lines of code, then understanding the GLBuffers, etc.. Also to communicate with the windowing system one has to use GLUT which is another framework.. Turns out that Nvidia's Fx composer is nice to play with shaders.. But I still would like to have a simple C or C++ program which just applies a given fragment shader to an image and displays the result. Does anybody have an example or is there a framework?

  • Ideas for Computer Science related Microteaching

    - by Roman Stolper
    This semester, I will be a TA for an introductory computer science course at my university. As part of TA training, I'll be doing something called Microteaching, which is where I teach for 5-7 minutes in front of a small audience (4-5 people) and I am reviewed on my teaching style. Among being critiqued on my personal things like confidence and eye contact, I will be critiqued on how well I know the subject material, as well as how interesting it is to the audience. So my question is: Can you offer me any suggestions of computer science related topics that: I can begin and finish teaching in a span of 5-7 minutes Are fun to learn about Are accessible to a general engineering (but not necessarily computer science) audience Some topics I have considered: Teaching how to write Hello World in some simple language Introducing a synchronization problem like dining philosophers

  • jQuery: How to smooth animated image resizing

    - by nikibrown
    I'm a jQuery noob - so please excuse the probable basicness of this question. I'm doing something pretty simple - on hover animate the position and size of an image. When you mouse over the images there are some noticeable 'jaggies' - is there a way to get rid of this? The jquery code is as follows and a live link is here kristechdev.metropoliscreative.com (hover over the icons). <script type="text/javascript"> $(document).ready(function() { $('#zoomNav li img').hoverIntent( function() { $(this).animate({'margin-top' :'-35px', 'margin-left' :'-10px', 'height' :'95px','width' : '79px' }, 'fast'); }, function() { $(this).animate({'margin-top' : '0px', 'margin-left' :'0px', 'height' :'70px','width' : '58px' }, 'fast'); }); }); </script>

  • Pet project ideas in Java

    - by Amir Rachum
    I'm looking for a pet project idea in Java. I'm a Software Engineering undergraduate finishing my 3rd year. I have also been working for the past 1.5-2 years programming in C++, and I get enough of that at work. I recently learned Java and I like it very much. Already done some project assignments and some really small console applications, but I'm looking for something to invest my time in. I would like a project that is complex enough to "brag about" (have it open sourced and get people interested, added to resume) and learn while doing it, but also simple enough to be able to at least have a working version in a few months. I know the most common advice is something that I need, but I admit I simply couldn't think of anything like that. Any ideas?

  • Echo mysql results in a loop?

    - by Roy D. Porter
    I am using turn.js to make a book. Every div within the 'deathnote' div becomes a new page. <div id="deathnote"> //starts book <div style="background-image:url(images/coverpage.jpg);"></div> //creates new page <div style="background-image:url(images/paper.jpg);"></div> //creates new page <div style="background-image:url(images/paper.jpg);"></div> //creates new page </div> //ends book What I am doing is trying to get 3 'content' (content being a name and cause of death) divs onto 1 page, and then generate a new page. So here is what i want: <div id="deathnote"> //starts book <div style="background-image:url(images/coverpage.jpg);"></div> //creates new page <div style="background-image:url(images/paper.jpg);"></div> //creates new page <div style="background-image:url(images/paper.jpg);"> //creates new page but leaves it open <div> CONTENT </div> <div> CONTENT </div> <div> CONTENT </div> </div> //ends the page </div> //ends book Seems simple enough, however the content is data from a MySQL DB, so i have to echo it in using PHP. Here is what i have so far <div id="deathnote"> <div style="background-image:url(images/coverpage.jpg);"></div> <div style="background-image:url(images/paper.jpg);"></div> <div style="background-image:url(images/paper.jpg);"></div> <div style="background-image:url(images/paper.jpg);"></div> <div style="background-image:url(images/paper.jpg);"></div> <div style="background-image:url(images/paper.jpg);"></div> <?php $pagecount = 0; $db = new mysqli('localhost', 'username', 'passw', 'DB'); if($db->connect_errno > 0){ die('Unable to connect to database [' . $db->connect_error .

IT IS SIMPLE CONNECTING SCRIPT THAT I KNOW WORKS //THE METHOD I AM HAVING TROUBLE WITH IS BELOW $pagecount = 0; while($row = $result->fetch_assoc()){ //GETS THE VALUE (and makes sure it isn't nothing echo '<div style="background-image:url(images/paper.jpg);">'; //THIS OPENS A NEW PAGE while ($pagecount !== 3) { //KEEPS COUNT OF HOW MUCH CONTENT DIVS IS ON THE PAGE while($row = $result->fetch_assoc()){ //START A CONTENT DIV echo '<div class="content"><div class="name">' . $row['victim'] .

The problem resides within the while loops. Any help is greatly appreciated. Thanks in advance guys. :)

  • How to read in a negative double with scanf() in C

    - by rize
    I'm learning basics of C and writing a simple first order equation solver. I want the input to be exactly ax+b=c or ax-b=c, where a, b, c are double type. I'm employing scanf() to read in user input and to check if it's of the correct form. However, if I enter a negative double, -4.6 say, as the "a" in the equation, scanf() won't read the a,b,c correctly. I'm using %lf inside scanf(). How do I read a negative double, then? Many thanks. My code: if (scanf("%lfx+%lf=%lf", &a, &b, &c)) more code If I use as the input "-6.2x+3.4=-5.9", the value 3.4 will be assinged to variable a, while b and c remain as they were and "more code" is run.

  • What's the straightforward way to implement one to many editing in list_editable in django admin?

    - by Nate Pinchot
    Given the following models: class Store(models.Model): name = models.CharField(max_length=150) class ItemGroup(models.Model): group = models.CharField(max_length=100) code = models.CharField(max_length=20) class ItemType(models.Model): store = models.ForeignKey(Store, on_delete=models.CASCADE, related_name="item_types") item_group = models.ForeignKey(ItemGroup) type = models.CharField(max_length=100) Inline's handle adding multiple item_types to a Store nicely when viewing a single Store. The content admin team would like to be able to edit stores and their types in bulk. Is there a simple way to implement Store.item_types in list_editable which also allows adding new records, similar to horizontal_filter? If not, is there a straightforward guide that shows how to implement a custom list_editable template? I've been Googling but haven't been able to come up with anything. Also, if there is a simpler or better way to set up these models that would make this easier to implement, feel free to comment.

  • compute mean in python for a generator

    - by nmaxwell
    Hi, I'm doing some statistics work, I have a (large) collection of random numbers to compute the mean of, I'd like to work with generators, because I just need to compute the mean, so I don't need to store the numbers. The problem is that numpy.mean breaks if you pass it a generator. I can write a simple function to do what I want, but I'm wondering if there's a proper, built-in way to do this? It would be nice if I could say "sum(values)/len(values)", but len doesn't work for genetators, and sum already consumed values. here's an example: import numpy def my_mean(values): n = 0 Sum = 0.0 try: while True: Sum += next(values) n += 1 except StopIteration: pass return float(Sum)/n X = [k for k in range(1,7)] Y = (k for k in range(1,7)) print numpy.mean(X) print my_mean(Y) these both give the same, correct, answer, buy my_mean doesn't work for lists, and numpy.mean doesn't work for generators. I really like the idea of working with generators, but details like this seem to spoil things. thanks for any help -nick

  • Best cheap GUI for converting to f4v

    - by Ben
    Hi, I need to give one client the ability to convert some videos to f4v h264 before loading it up to an AIR app. I normally doing with the Adobe Media Encoder CS4 but that only ships with adobe products (you can't download it as a free standalone app - which, start rant is odd, you'd think they would push the format - Microsoft's competing expresssion encoder is free end rant) Anyway, I need to get a (hopefully not too expensive, but willing to pay for it) good 3rd part app that can take any video and convert it to an f4v. Can you suggest any? Everything i've found is horrible or jammed with ads and crap. What would you use? Any suggestion? (please don't just say ffmpeg - I know it can do it but we need to good simple GUI) Thanks!

  • Looking for a good implementation that will access multiple databases simultaneously

    - by eibhrum
    I just want to find out if there's a good implementation (in C#/ASP.NET) on how to access my records from my different databases simultaneously. I have this simple application which suppose to search on these databases, then, display the record if a certain keyword is matched. I have like 5 databases (currently using MySQL) all in all and will be expanding it on the future (might be changing to SQL Server). I am fully aware on how to search on a single database, while I'm still learning how do it in multiple databases. Any tips, comments or suggestions?

    Hi Guys! I made a custom component which simple extends a WebView This component is used into activities that are loaded from a tabhost. This component creates a timertask too. I'd like to execute the task only if the activity that contains the component is visible. Ex: public class MyWebView extends WebView { public MyWebView(Context context, AttributeSet as) { super(context,as); /** More code **/ TimerTask ttask = new TimerTask() { @Override public void run() { if (iamvisible) doStuff(); } }; timer = new Timer(); timer.schedule(ttask, refreshInterval * 1000, refreshInterval * 1000); } } How can I set the iamvisible variable? I tried overriding onWindowFocusChanged and onWindowVisibilityChanged but with no luck Regards in advance

  • How to let an average user design a boolean expression graphically

    - by Svein Bringsli
    In our application there's a list of customers, and a list of keywords (among other things). Each customer can have a number of keywords, but it's not mandatory. So for instance, one customer can have the keywords "retail" and "chain", one can have only "contractor" and a third can have none at all. I want to let the user make a selection of customers based on these keywords, but not having to write (retail AND chain) or contractor and not wholesale I would like to make it as user-friendly as possible, and ideally with only "simple" controls, like checkboxes, comboboxes etc. Does anyone have any suggestions on how to design this? Or maybe some examples of applications where there are similar functionality?

  • Is there a lightweight datagrid alternative in Flex ?

    - by Wayne
    What is the most performant way of displaying a table of data in Flex? Are there alternatives to the native Flex Datagrid Component? Alternatives that are noted for their rendering speed? Are there other ways to display a table? I have a datagrid with roughly 70 lines and 7 columns of simple text data. This is currently created and loaded in memory. This is being refreshed rapidly (about 800 msec) and there is a slight lag in other animations when it is rendering the table... So I am trying to cut down this render time.

  • ColdFusion static key/value list?

    - by richardtallent
    I have a database table that is a dictionary of defined terms -- key, value. I want to load the dictionary in the application scope from the database, and keep it there for performance (it doesn't change). I gather this is probably some sort of "struct," but I'm extremely new to ColdFusion (helping out another team). Then, I'd like to do some simple string replacement on some strings being output to the browser, looping through the defined terms and replacing the terms with some HTML to define the terms (a hover or a link, details to be worked out later, not important). Can anyone point me in the right direction of: How to define the stucture (if that is what I need for a key/value pair list) How to query at the application start-up and reuse the list properly The best way to do the string replacement

  • Does Flash10 + p2p really work?

    - by snitko
    I've been googling around and I still can't get it. Some people say: here you go, just use it. Others claim it has certain restrictions that does not allow you to use p2p the way you want it in Flash. So, here's a simple question: is it possible to implement a Flash10 application, that uses some of the existing torrent files to stream video/audio right into the user's browser? If no - why? Is there any possible workaround for this 'no'? If yes - what are the difficulties of the implementation and why have no one actually done it yet?

  • Solution: Android INSTALL_FAILED_INSUFFICIENT_STORAGE error.

    - by Andrew Smith
    The INSTALL_FAILED_INSUFFICIENT_STORAGE error is the bane of every Android developer's life. It happens regardless of app size, or how much storage is available. Rebooting the target device fixes the problem briefly, but it soon comes back. There are hundreds (if not thousands) of message board posts from people asking why the problem occurs, but the folks at Google are frustratingly silent on the issue. There is a simple workaround. If your test device is running Android 2.2 or later then add the android:installLocation attribute to your application's manifest file, with the value "preferExternal". This will force the app to be installed on the device's external storage, such as a phone's SD card. For example: <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.andrewsmith.android.darkness" android:installLocation="preferExternal" This is more of a band-aid than a fix, and it may not be ideal if you want your finished app to install on the device's internal memory. But it will at least make the development process a lot less frustrating.
