16,845,332 | 1 | 17,795,338 | Bear with me. I have a ComboBox (WPF) in 'autocomplete' mode.
Easy peasy right? Just set IsEditable to true.
'''
<ComboBox
IsEditable="True"
Text="{Binding Model.TextEntered}"
ItemsSource="{Binding Model.ListWithOptions}"/>
'''
I've got my ComboBox and it autocomplete's just perfect.
BUT when I enter the following text 'caaaaa' it changes it to 'CAaaaa'. I understand the ComboBox autocomplete's the text and match the casing. But when I want to enter caaaaa (for whatever reason) I don't want 'CAaaaa'.
Any idea to solve this?
As an alternative I would settle for (if all else fails):
-
<IMAGE> | Have you tried setting 'ShouldPreserveUserEnteredPrefix="True"'? This will not alter the case that is typed into the 'Combobox' but will still match items in the list. So in your example if you type 'ca13' it will find and select 'CA132S', but it will be displayed in the combobox as 'ca132s' (in the case that it was typed in).
A compromise in the way that the item is displayed perhaps, but it will select the correct item and allow you to type characters in either case without alteration. | |

The only issue you'll have with skinned buttons is that you'll need to be sure you are using 32bit pngs (with a transparency layer) as your button skins.
Here's a code chunk for doing button skins - they get set as the background of the button object and you place them in the drawable folder along side your images.

Thanks! | Personally i think you should go for an image in this case. Definitely for such a simple png, it is not worth the effort imo, and you will have the best cross browser support. And I also believe that when it comes to logo's, you need full cross browser compatibility. It is what defines your brand, and the way people will recognize you, so no variations should be allowed.
If you insist on 'coding' your logo, I think you should go for an svg for the closest possible match. I would probably replicate the logo in Illustrator (if you do not have it there already) and save it as an svg from there. Integrating it in a webpage should be easy then... | |
16,309,915 | 1 | 16,318,864 | I'm having alot of trouble setting up log4J on windows. I am reading the <URL> but it's not really clicking:
So this is how I set my System Variable:
<IMAGE>
The full var. value is :
'''
C:pache-log4j-2.0-beta4-bin\orgpache\logging\log4j\core
'''
And then I add the LOG4J_HOME variable tothe PATH variable.
But I still get errors when compiling. Does anybody have pointers on this?
Thank You Very Much | Let's see, you have unzipped the apache-log4j-2.0-beta4-bin.zip to C:\ drive.
This gives you a whole bunch of jar files in that directory.
Instead, when you compile your java program, you add some of these jar files to the classpath.
You probably only need to add
1. log4j-api-2.0-beta4.jar
2. log4j-core-2.0-beta4.jar
These two jar files are usually enough. The other jar files are helpers for special cases. Some cannot be used together, so don't just add all of them!
The details of how to add these jar files to the classpath when compiling depends on what you are using to compile.
By the way, log4j 2.0 beta5 was released recently with some new features and lots of bugfixes. | |
10,701,189 | 1 | 10,701,817 | I have several forms in a project I am working on, each form contains their own different properties and value edits such as TEdits, TTrackBars and TSpinEdits etc. These forms work in a similar way to how a InputBox Dialog works where it displays the form, you enter a value and if the ModalResult is mrOk you handle the result accordingly.
I am now realising that this is not the most practical solution especially with several forms, and even more to add. I think the best GUI design option here would be something similar to the trusty Delphi Object Inspector on the Main form, it would also be easier to maintain.
What I don't need though is an Object Inspector that displays properties from a component class, but instead I want to populate the Object Inspector with my own fields and types.
So far the only component I have found that comes close is the Berg NextInspector found here: <URL> which allows filling the Object Inspector with your own data:
<IMAGE>
I would like to see the alternatives before considering purchasing the above so I can weigh up my other options and compare the pros and cons between different component libraries.

29,589,816 | 1 | 29,592,155 | I am having a strange problem here. I have a UIScrollView that is setup in the interface builder. I add content to it via a method called setupScrollView which is as follows :
'''
-(void)setupScrollView {
UIView *content = [[UIView alloc] initWithFrame:CGRectMake(0, 0, self.scrollView.frame.size.width*[self.stickers count], self.scrollView.frame.size.height)];

UIImageView *imageView= [[UIImageView alloc] initWithFrame:CGRectMake(i*self.scrollView.frame.size.width, 0, self.scrollView.frame.size.width, self.scrollView.frame.size.height)];

17,882,554 | 1 | 17,883,688 | It has recently come to my attention that Java text components use line feed characters (LF, '
', 0x0A) to represent and interpret line breaks internally. This came as quite a surprise to me and puts my assumption, that using 'System.getProperty('line.separator')' is a good practice, under a question mark.
It would appear that whenever you are dealing with a text component you should be very careful when using the mentioned property, since if you use 'JTextComponent.setText(String)' you might end up with a component that contains invisible newlines (CRs for example). This might not seem that important, unless the content of the text component can be saved to a file. If you save and open the text to a file using the methods that are provided by all text components, your hidden newlines suddenly materialize in the component upon the file being re-opened. The reason for that seems to be that 'JTextComponent.read(...)' method does the normalization.
So why doesn't 'JTextComponent.setText(String)' normalize line endings? Or any other method that allows text to be modified within a text component for that matter? Is using 'System.getProperty('line.separator')' a good practice when dealing with text components? Is it a good practice at all?

An example of what this program saves on my windows machine after adding a new line of text (why the single CR? o_O):
<IMAGE>
I ran/debugged this from within Netbeans IDE, which uses JDK1.7u15 64bit (C:\Program Files\Java\jdk1.7.0_15) on Windows 7. | First of all, the real answer is that this is how the designers thought the design should work. You'd really need to ask to get the real reason(s).
Having said that:
> So why doesn't JTextComponent.setText(String) normalize line endings?
I think that the most likely reasons are:
- It would be unexpected behaviour. Most programmers would expect a 'get' on a text field to return the same string value that was 'set' ... or that the user entered. - If text fields normalize, then the programmer would have great difficulty preserving the original text's line endings in vases where this was desirable.- The designers have wanted to change their minds at some point (c.f. the reported behaviour of the 'read' and 'write' methods) bur were unable to for reasons of compatibility.
Anyway, if you need normalization, there's nothing stopping your code from doing this on the value retrieved by the setter.
> Or any other method that allows text to be modified within a text component for that matter?
It is reported (see comments) that 'read' and/or 'write' do normalization.
> Is using System.getProperty('line.separator') a good practice when dealing with text components? Is it a good practice at all?
It depends on the context. If you know you are reading and writing files to be processed on "this" platform, its probably a good idea. If the file is intended to be read on a different platform (with a different line separators) then normalizing to match the current machine's convention is maybe a bad idea.

I believe this menu is called the "Window Control Menu", but I am not sure.

30,191,996 | 1 | 30,192,199 | I have a homepage that showing the value of incomes and expenses. Right now the values just appear on the the screen, however is was wondering whether i can make those number start from 0 and then have an animation to increment that value, like a stopwatch. Is it also possible to make the final number after the increment has finished to animate with a pulse".

Probably there are other mistackes, but I don't know how to go over this one.
What's wrong? Thank you!
PS: I read <URL> but I didn't understand why and how that works | Alessio, In Java, you have 2 types of Exceptions :
- -
When a method can trigger a "checked" exception, you have to handle it.
To do so you have 2 ways:
- - <URL>
In your case, IOException is a "checked" exception and thus you should add a "throws IOException" to your 'getR' method or handle it with a try catch. | |

> Some screenshots for reference<IMAGE>
<URL> | Few pointers here :
1. Inside your AndroidManifest.xml : <meta-data android:name="com.google.android.maps.v2.API_KEY" android:value="***********************************" /> Should be located inside the <application> tag
2. You did not have the google-play-services_lib inside your project manager, here's what I had on my setup : Notice there, I have the google-play-services_lib.jar with the google-play-services.jar, you will need to import the Google Play Services Library into your workspace, make sure the project is open, then import it as library for other projects
Good Luck!!
<URL>
Now, I suggest you to do more research about this problem, here's how :
1. Try displaying only the map on your application, if the map displays, then your layout declaration has errors. If the app crashes,then you have library-referencing error.
2. If the referencing error occurs, try creating a new project, import the google-play-services_lib into your project, and try displaying the map first. When it displays, modify your code to match the current code you have here.
Good luck :D | |

I don't understand why I can't successfully plot the gauss curves...
Any explanations? | I can now fit gaussians curves on my data
I still can't understand how Jannick found the 'p0' for the curve fit, but it works.
I created a 3 dimensional array with positions and amplitudes of peaks and used a 'while' loop for the 'rang_gauss'. I used the scipy 'curve_fit' properly with my 3D array, and corrected the amplitudes with a coefficient 'f'.

I've also tried adding this block under '<adminhtml>', but it when I try editing role permissions I get a white page with this error: 'Fatal error: Class 'Mage_Mynamespace_Donor_Helper_Data' not found in /home/mysite/public_html/magento_dev_1_10/app/Mage.php on line 520'

The ultimate goal is to have a new tab in the admin area for managing Donors and related data in the system. When you click on some menu item, I'd like to show a grid and have sub-tabs and stuff like that. I'm looking to override the adminhtml controller - although I am extending it per <URL>:
> The only difference from a standard
controller here is that we're
extending
Mage_Adminhtml_Controller_Action
instead of
Mage_Core_Controller_Varien_Action.
Mage_Adminhtml_Controller_Action
contains important code for validating
the admin session, as well as several
methods that are useful in an Admin
Console context.
So in this picture, clicking that first sub-menu item should call the Index action of my controller and show a grid or something to manage the Donors.

Why is 'NSURLSession' causing these memory leaks? I am invalidating the 'NSURLSession' when I am finished with it. I am also releasing any properties that I do not need and setting the session to nil (refer to - (void)cleanupSession & - (void) endSessionAndCancelTasks).
The memory leaks occur after the session has completed and "cleaned up". Sometimes, they also occur after I have popped the 'UIViewController'. But, all of my custom (GPPhotoRequest and GPSearch) objects and UIViewController are being dealloced (I've made sure by adding an NSLog).
I tried not to post to much code, but I felt like most of it needed to be seen.
Please let me know if you need any more information. Help is greatly appreciated. | After rereading the <URL> it turns that I was setting the 'NSURLSession' property to nil too early.
Instead, I need to set the 'NSURLSession' property to nil AFTER I receive the delegate message 'URLSession:(NSURLSession *)session didBecomeInvalidWithError:(NSError *)error', which makes sense. Luckily, it was a minor mistake.
E.g.
'''

Given the heights I've applied to my div elements I expected everything to line up nicely however it appears that the bottom div is higher than the intended 15% and overlaps onto the middle div, see here demonstrated by the red border at the bottom... <IMAGE>
Where am I going wrong? I'm sure it's something simple. | You should understand how the box model works... You are using borders which are counted outside the element, so for example if your element is '200px' in height, and has a 5px border, the total element size will be '210px;'
<IMAGE>
So considering this as the concept, what you are having elements which sums up to '100%', and you are using borders too, so that is exceeding the viewport which will result in vertical scroll...
Also you don't have to use 'position: absolute;', you are making it absolute, just to avoid scrolls but that's a wrong approach. Absolute element is out of the document flow, and will give weird results if you didn't wrapped inside a 'position: relative;' element.
<URL>
Few Tips :
- Use lowercase tags - Avoid Uppercase ID's unless required
Using 100% vertically is very rare, designers generally use 'width: 100%;' for making the layouts responsive. So if you don't have any specific reason to go for '100%' vertical elements, don't go for it..
---
Solution:
Still if you want to stick with the vertical layout spanning to 100% in height, you should use 'box-sizing: border-box;' property...
What 'box-sizing' will do here?
Well, using the above property, it will change the default behavior of the box-model, so instead of counting the borders, paddings etc outside the element, it will count inside it, thus it will prevent the viewport to be scrolled.
I will provide you an example, which I had made for <URL>.
<URL>
Explanation for the above demo, if you look at the CSS, I am using
'''
* {
-moz-box-sizing: border-box;
-webkit-box-sizing: border-box;
box-sizing: border-box;
}
'''
which will make every element paddings, borders etc to be counted inside the element and not outside, if you mark, am using a border of '5px;' and still, the window won't get a scroll bar as the border is counted inside the element and not outside. | |
25,062,175 | 1 | 25,062,589 | I have a number of data images like the one below, in which I appended a new set of axes to the right to force the colorbar to be the same size as the image.
<IMAGE>
The ticks on the colorbar are too close together, so I'd like to reduce their number. I attempted to do it this way:
'''
# Set up colorbar
divider = make_axes_locatable(plt.gca())
cax = divider.append_axes("right", size="5%", pad=0.05)
cax.yaxis.set_major_locator(plticker.LinearLocator(numticks=5))
cbar = plt.colorbar(im, cax=cax)
cbar.set_label(cbtitle, **cbkw)
'''
I know that, in general, re-formatting axes in this way requires a call to a 'cbar.update_axis()' to force the update, but that didn't seem to work here. 'cax' is an Axes object, and calling 'cbar.update_axis()' doesn't do anything either. In fact, both strategies, as well as leaving the update out, result in the image above. Does anybody know how I can reduce the ticks? | Your sample code contains a lot of variables which are defined outside of it, so its hard to see all the things you're doing. But with regard to setting the number of ticks on the cbar, this works for me:
'''
fig, ax = plt.subplots()
im = ax.imshow(np.random.randn(10,10), interpolation='none')
divider = make_axes_locatable(ax)
cax = divider.append_axes("right", size="5%", pad=0.05)
cbar = plt.colorbar(im, cax=cax, ticks=mpl.ticker.LinearLocator(numticks=3))

Any help will be much appreciated. | If you aren't keen on ajax you can wrap that whole grid in a form then using the checked event on the checkbox grab the id of that checkbox so you know specifically which value to look at when the form post. You'll have to tie each checkbox to it's associated textbox via an identifier in the id, cause it will post all the values of the grid. Having multiple forms on a page is something you would do if the page were sectioned where each section performs specific functionality. In this case the grid is performing one piece of functionality across the entire grid.
In lieu of that, and ajax style approach is going to be the best bet. Using jquery it would be fairly each to attach a ajax.post to each element in the grid that you want to make a post for. much cleaner than trying to write all the extra code to figure out what checkbox was altered and what the data is that you want to look at from the post.

11,769,163 | 1 | 11,905,623 | I am currently working on an application that will create a TV Guide application in C# .NET. The issue is that when a user selects an option to open the TV Guide, I would like to keep the current stream playing, but minimize it to the upper right corner and keep it playing while allowing the user to browse the EPG data and have a smaller video playing.
Should I just place all of the labels/buttons/etc. over the top of the Panel (what I use to display the actual video in), and hide/show them as needed, or is there a better approach to this?
On a side note, I am assuming Labels will be the best solution for the displaying the current channel information in, but if there are any better options, I would love to hear them.
<IMAGE> | I am going to answer based on the assumption that this is a native windows winforms app running in windows. If this is incorrect, please edit your question and provide more details about your project and target platform.
## Choice #1 is DirectX
These kind of multimedia apps are really best written using DirectX. You are essentially writing a "game" from a video performance perspective (and possible user input perspective too). You want to maintain video streaming while displaying a menu (perhaps even animating the menu). DirectX will allow you take advantage of modern graphics processors to draw/render a nice menu/ui with video somewhere on the screen.
Could you do this without writing your own menu rendering using DirectX? Probably. But it would be heavy and likely to impact system perfrmance or at the very least video performance and overall application performance.
So Choice #1 is DirectX - There will be examples of this kind of programming by searching the web for 'C# game programming'.
Using something like DirectX and handling user input over the entire app surface will allow a lot more control over user input too. For example you might decide to support drag style scrolling. The whole menu could smoothly scroll up to expose more channel below, etc... This is going to be very dificult with a collection of numerous winform controls like buttons and rather easy (or at least realistic) with DirectX.
## Choice #2 - Winforms
Ok now Choice #2 that you were hinting at in your question was using native C# controls like button, label, panel, etc. You could make this work, but you will be sacrificing a lot feature capabilities and costing a lot in performance.
For example lets look at the screen shot you posted. I assume that table would be divided up into buttons where each cell is one button on the panel? You could click a channel to select it or click a show to start watching that one? (I'm guessing here.) It looks like at least 22 buttons in that screen shot. Now lets say you scroll the screen either down to expose more channels or right to look later in the timeline, that operations will need to destroy/dispose of all your buttons, figure out what new buttons it needs, create them all, size/position them and add them to your panel (particularly in the shows area where the length of show/block size will change for every chanel at any point in time). That operation of destroying buttons and creating buttons is clunky, its costs a lot of performance, will likely blink the UI at least once and won't animate smoothly. Also the user interaction is local to each individual button, it would be very dificult to implement something like swipe style scrolling as each button has its own mouse events, etc..
Ok I just thought of one more winforms technique, an aweful one but I know it'll pop into your head! What if you made a panel with scrollbars that contained a massive array of buttons for all the available channels? This gives you smoother scrolling and reduces the destroy/create new button issues, right? Well that'll be a performance nightmare too! Try putting 100-200 buttons in a scrolling panel and you'll find out quickly this is a bad idea.
## Better Winforms Techniques
If you must go the winforms route (because you can't/won't use DirectX) then you should implement the menu in a DirectX style way.
1. Create a menu control class which inherits from a panel
2. Override the drawing/painting (Control.OnPaintBackground and Control.OnPaint), override keyboard and mouse handlers, etc.
3. Draw the menu inside the panel using the .Net Graphics class (provided in the OnPaint event PaintEventArgs)
4. Handle all mouse/keyboard events and redraw your control when necessary (using Control.Invalidate() or Control.Refresh().
You won't get DirectX performance, but it'll be way better than a large array of controls. (You'll have the technique correct, but may not get the performance benefits of graphics processor acceleration that DirectX can harness.) | |

Screenshot:
<IMAGE> | There is option of 'frictionless requests'.
On Facebook developer site they mentioned in section of 'Invites and Requests'
> We touched on a scenario where users exchange requests back and forth. If this scenario is typical in your game, it can be a bad user experience to force them through the request dialog every time they want to send a request. The solution for this is frictionless requests.
Frictionless requests let users send requests to friends from an app without having to click on a pop-up confirmation dialog. When sending a request to a friend, a user can authorize the app to send subsequent requests to the same friend without another dialog. This streamlines the process of sharing with friends.

1. Add the spaces to the new elements created with javascript
2. Remove the spaces from the original html and adjust the margins
3. Use a template

27,995,957 | 1 | 27,996,039 | I'm studying web services using Java, and wondering if it's possible or not.
I've made a RESTful service client using a Java client Library, which is following REST's principles.
(To be more specific, I found this library on Github and am using it. This Java library interacts with CKAN, which is a sort of web-based open source data system)
Then, I wondered (am still wondering) if this REST client can work as a server for a SOAP web service, as this picture describes.
<IMAGE>
I tried it by creating a web service class within an EJB. I wrote almost the same code as the REST client into the EJB's web service class, so that the web service class would use the GET, POST and DELETE methods.
However, when I try to deploy this EJB (a SOAP web service), the Glassfish server indicates that...
'Two web services are being deployed with the same endpoint URL ckan/ckan; The service that gets loaded last will always be the one that is active for this URL.'
'Exception while invoking class org.glassfish.ejb.startup.EjbDeployer load method'
'java.lang.RuntimeException: EJB Container initialization error'
It might be just because I've already made a REST client which is using the same URL, but I haven't found the very reason.
Do you think, in SOAP web service, it is possible for the server side to have the standardized server methods (i.e. GET/POST/DELETE etc) in order to interact with an outside data repository (which is, in my case, CKAN ... a web-based data management system)?
Any insight will be appreciated.
The purpose of using a REST client as a server of a SOAP is to test security issues of REST and SOAP and compare them.
I don't think it is practical to use a REST client in such a way. | If I understand your question correctly, for study (not practical) reasons, you want to have a REST web service invoke a SOAP web service (or vice versa). With some of the older libraries this was not possible because of design/code issues in the libraries. However, that is no longer true if you are using current versions of libraries.
Build a REST service with the API you want (spring libraries will do this nicely), and map the controller methods to the SOAP webservice you want to invoke (or vice versa). You're talking about a couple of controller classes with Spring annotations and some wrapper code and Java EE fluff.
If I understood the problem backwards, the answer is essentially the same - just exchange the SOAP and REST annotations. | |

''' | Firstly, if your 'getRayDirection()' is doing what it says it is, it's producing a direction, and not a gaze point, so you should not be subtracting the ray origin from it, which is a point.
(Although directions and points are both represented by vectors, it does not make sense
to add a point to a direction)
Also, you are normalising 'L1' and then taking its magnitude and dividing each of its components by that magnitude, to produce 'UnitVector', which you then call 'normalize' on . This is unnecessary: The magnitude of 'L1' after the first normalization is 1, you're normalizing the same vector 3 times, just use 'L1'.
The last issue, is that of clamping. The variable you call 'Factor' is the value 'cos(th)' where 'th' is the angle between the direction of light and the normal. But 'cos(th)' has a range of '[1,-1]' and you want a range of only '[0,1]', so you must clamp 'Factor' to that range:
'''
Factor = max(0, min( NormalIntersect.dotProduct(UnitVector), 1));
'''
(And remove the 'min' calls in your production of 'color').
This clamping is necessary for faces whose normals are facing away from the light, which will have negative 'cos(th)' values. The angle between their normal and the direction of light are greater than 'pi/2'. Intuitively, they should appear as dark as possible with respect to the light in question, so we clamp them to 0).
Here's my final version of the code, which work. I'm going to work on the assumption that you have 'scale(float)' and 'operator +(const TVector &)' etc defined on your 'TVector' class, because they will quite plainly make your life easier. Also, for brevity, I'm going to call 'NormalIntersect', just 'normal':

'''
[remote "mine"]
url = [email protected]:unphased/oh-myu-zsh.git
fetch= +refs/heads/*:refs/remotes/origin/*
'''
It maps to the same remotes as origin. It should be:
'''
fetch= +refs/heads/*:refs/remotes/mine/*
'''
The part before ':' configures which branches on the remote that are supposed to be fetched. The part after ':' configures where in the local repository those are supposed to be copied to. So, since you call the remote repository 'mine' in your repository, you should map the remote branches to a directory named 'remotes/mine' in your repository.
In the future, when adding a remote, rather than editing the config directly, it is easier to use the 'remote add' command:
'''
git remote add mine [email protected]:unphased/oh-myu-zsh.git
'''
Also, when adding a tracking branch, rather than editing the config directly, it is easier to do this (though you got that configuration right anyway):
'''
git branch --track mine-master mine/master

''' | It means that the memory allocation/deallocation functions have detected a serious problem in the heap, one that means using it is probably not safe to continue.
To understand this, realise that a heap almost always consists of data blocks control information intermixed in memory (not totally required but most implementations would probably do it that way).
If you write beyond the end of an allocated block, you're therefore likely to corrupt some control information, such as with:
'''
char *twoBytes = malloc(2);
memset (twoBytes, '', 10000);
'''
Even assuming there's some free space at the end of the two bytes to make the allocations efficient (and you, as a developer, should assume this), writing ten thousand bytes will almost certainly cause some severe damage.
Unfortunately, errors in the heap are rarely detected close to where they happen, so you'll need to examine your code for places where you may be writing beyond the ends of buffers. Another alternative is to use a tool like 'valgrind' to detect suspect writes. | |

''' | I think the main issue is with the use of "distinct." This is not a coding problem. When summing distinct on multiple grouping levels, the totals of sub-groups may be greater than the total of the top group. For example:
'''
GroupId Value
1 1
1 2
1 3
2 2
2 4
2 5
'''
Sum(distinct value) on group 1 = 6
sum(distinct value) on group 2 = 11
sum(distinct value) on both groups = 15
Also, in general, it sounds like you are asking for a neater way to solve this problem of multiple grouping levels in a single recordset. I did something like this at a previous job:

The idea is that you build the list of possible groups first in a CTE as
'''
Level1 Level2 Level3
A NULL NULL
A AA NULL
A AB NULL
A AA AAA
A AA AAB
A AB ABA
A AB ABB
'''

23,849,669 | 1 | 23,850,889 | The question is quite simple and I don't know where and how to implement the transfer functions.
Let's say that I have a classic system
<IMAGE>
where P has a transfer function of the second order with zita=0.7, F=1 and C is the process regulator.
I would like to implement this regulator on a controller like ATMega128P in C or C++.
The transfer function of the process is identified by experimental methods and the regulator may vary depending on the process transfer function.
Where should I start? | If you have your transfer function it in continuous time (Laplace), you will need to transform it in discrete time (Z-Transform), using one of the discretization methods (forward difference, backward difference, trapezoidal).
Once you have the discrete transfer function, you will need to apply inverse Z transform to obtain the system's equation in the time domain. Next, you will need to detrmine the discretization step.
When if you have this data, you can implement this system on the microcontroller quite easily, since practically you will only implement a simple equation which will probably read a sensor periodically through an ADC input and according to that and previous input (y[k], y[k-1], ...) values will generate the control value (u[k]) according to its reference (r[k]).
The ADC (y[k]) can be read using in a timer interrupt, set to fire according to your discretization step. Once the value is read, you can compute u[k] and set the execution element accordingly.
For implementation, I would recommend C, since C++ would probably be a little bit of an overkill in this case (most embedded systems which implement a system such as this one are programmed using ANSI C or MISRA C - especially in automotive).
Before jumping to C, I would first try to see if I got the calculations correctly and I would simulate the system in Simulink (MATLAB), or Scilab.
For tuning the real embedded system, I would recommend reading about the Ziegler-Nichols method.

20,909,313 | 1 | 20,909,682 | I am a newbie in Swing and I am using a JTable object in order to display some information.
Basically the frame contains a JPanel -> GridBagLayout manager.
The JPanel contains a JLabel ("Status Table"), a JScrollPane which contains the JTable, the "Sort by" JButton and a JComboBox.
How can I set the width of the columns/ column headers in order to completely display the text contained in them?
I tried to use
'''
table.getColumnModel().getColumn(i).setPreferredWidth(my_width);
'''
but the problem is that in order to achieve the results I want, the sum of all the columns' widths is larger than the JScrollPane's width, so nothing will happen, they will remain the same as before.
I tried to use the setSize method for JScrollPane in order to resize it to be as large as the window... but because of the GridBagLayout manager it seems that it cannot get larger than a certain size, which still doesn't fit the text.
Additional info:
The JTable is built from a model that I've implemented and the only GridBagConstraints that I've modified are gridx, gridy and fill = BOTH.
<IMAGE> | See the <URL> for an easy way to size each column.
Only the table should be added to the scrollpane. You may also need to use:
'''
table.setAutoResizeMode( JTable.AUTO_RESIZE_OFF );
'''
To allow each column to be displayed at its preferred size.
> the sum of all the columns' widths is larger than the JScrollPane's width, so nothing will happen,
You have a problem with the gridbag constaints. The component should grow to fill all the space. Maybe it will be easier to use a BorderLayout. Add the scrollpane to the center and add the other components to the north/south. You can nest panels with different layout managers to get your desired layout. | |

1- What exactly is <PHONE>? (See Local window)
2- What is the value at the address: 0x00110000
3- Why is this address only 16 bits? On a 32 bit OS, should it not be 32 bit?
Sorry it was my mistake, it is 32 bit as pointed out in the comment below. | > 1- What exactly is <PHONE>? (See Local window)
It is the 'float' quantity contained at the address 0x00110000 We expect a 'float' representation, because the variable 'A', a '__device__' 'float' pointer, should be pointing to a 'float' quantity:
'''
A = 0x00110000
*A = <PHONE>
'''
> 2- What is the value at the address: 0x00110000
The value at that address is <PHONE> expressed as a 'float' quantity, or 0x3e4de99c expressed as a 32-bit hexadecimal quantity (e.g. hexadecimal unsigned integer).
> 3- Why is this address only 16 bits? On a 32 bit OS, should it not be 32 bit? Sorry it was my mistake, it is 32 bit as pointed out in the comment below.
The address is actually 32 bits. Each hexadecimal digit constitutes 4 bits, and there are 8 digits.
> what info is given by Memory window? Is there <PHONE> in that window?
The memory window also shows you what is stored in memory starting at the memory address 0x00110000 (in this case), but it shows you the data byte-by-byte. For example, if you took the first 4 bytes and rearranged them into a 32-bit quantity (so, 0x3e4de99c) you would have the float representation of <PHONE>. | |

30,406,707 | 1 | 30,406,858 | Look at this short class.
What does it do? It is a HashMap where the key is a Class object and the value is a Hashmap with key and value of the type which is defined by the Class object.
Say you want to have a method add(K obj), that will be a convenience method. Why would you force a user to type add(Person.class, personInstance), when you can also let him just pass you the instance itself - the code should be able to take the class of the object and put the instance under the key being the class of the object. But I can't. The add(K obj) convenience method does not compile:
'''
public class TypedHashmap extends HashMap<Class, HashMap> {
public <K> HashMap<K, K> getHashMap(Class<K> type) {
return (HashMap<K, K>) getOrDefault(type, new HashMap<K, K>());
}
public <K> void add(K obj, Class<K> type) {
HashMap<K, K> toModify = getHashMap(type);
toModify.put(obj, obj);
}
public <K> void add(K obj) {
add(obj, obj.getClass());
}
}
'''
The compile error:
<IMAGE>
I can see that Java is not sure about obj.getClass() type. But I do not see why. Is it because it cannot ensure that the class is not actually something extending the K? What is the problem here? Can this be somehow worked around? | Generics are a tool to ensure type safety.
The way you have designed your API, it is type safe to this level, which is why you get this error.
'''
public <K> void add(K obj) {
add(obj, (Class<K>) obj.getClass());
}
'''
Is the way to make it explicit that you cannot ensure type saftey here. Or just do a
'''
public void add(Object obj) {
add(obj, (Class<Object>) obj.getClass());
}
'''
If you want a slightly cleaner solution (no cast in the simpler add function), you'll have to modify your other add function, too.
'''
public <K> void add(K obj, Class<? super K> type) {
HashMap<K, K> toModify = getHashMap(type);
toModify.put(obj, obj);
}
public void add(Object obj) {
add(obj, obj.getClass());
}
'''
But in the end I believe .
The problem is this:
'''
Number a = new Integer(3);
map.add(a);
map.getHashMap(Number.class).contains(a);
'''
yields false. The Integer is in the 'Number' map. Because your maps do not support subtypes and inheritance.

Please guide me where is the actual problem lies. | This is being caused by trying to create a NSString object with a 'NULL' string. It is on one of these lines:
'''
[[NSString alloc] initWithUTF8String:(const char *) sqlite3_column_text(statement, ...)];
'''
So, before you create a NSString with the results of the sql statement you need to check for NULL like this:
'''
char *tmp = sqlite3_column_text(statement, 1);
if (tmp == NULL)
strRestaurantName = nil;
else
strRestaurantName = [[NSString alloc] initWithUTF8String:tmp];

28,982,213 | 1 | 28,982,430 | I'm using a AdapterView for a ListView, the activity where we can find the list view and an EditText.
When we click on one element of the ListView we go to the second activity, and I want to send the data of the selected item as an extra in a intent.This data will then be shown in the EditText
I tried this code, but it doesn't seem to work, it shows always the default value of the EditText.
here is the code of the adapter view :
'''
public class adapterq extends ArrayAdapter<Questionaire> {
Bitmap image;
public adapterq(Context context, ArrayList<Questionaire> questionaires) {
super(context, 0, questionaires);
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
final Questionaire c = getItem(position);
View convertView2;
if (convertView == null) {
convertView = LayoutInflater.from(getContext()).inflate(R.layout.customquest, parent, false);
convertView2 = LayoutInflater.from(getContext()).inflate(R.layout.activity_main, parent, false);
}else{
convertView2 = (View) convertView.getTag();
}
TextView q = (TextView) convertView.findViewById(R.id.textView1);
final EditText name = (EditText) convertView2.findViewById(R.id.editText1);
q.setText(c.getLabel());
convertView.setOnClickListener(new OnClickListener(){
@Override
public void onClick(View v) {
Intent intent = new Intent();
intent.setClass(getContext(), Questions.class);
intent.putExtra("name", name.getText().toString());
intent.putExtra("category", c.getCode());
getContext().startActivity(intent);
v.setBackgroundResource(R.drawable.yourbackground);
((Activity) getContext()).overridePendingTransition(R.anim.right_slide_in, R.anim.right_slide_out);
}
});
convertView.setTag(convertView2);
return convertView;
}
}
'''
<IMAGE> | You should use the <URL> instead. The callback returns what position in the list was clicked and the view. The position is used to retrieve the data object 'Questionere'.
The 'EditText' may be retrieved using a 'findViewById()'.
'''
ListView list = (ListView) findViewById(R.id.listview);
list.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Questionaire item = list.getItemAtPosition(position);
String name = ((EditText) findViewById(R.id.editText1)).getText().toString();
Intent intent = new Intent();
intent.setClass(getContext(), Questions.class);
intent.putExtra("name", name);
intent.putExtra("category", item.getCode());
startActivity(intent);
}
});

20,479,209 | 1 | 20,481,296 | I have two laptops and on one of them in Eclipse I was able to add a type hierarchy that shows class members, etc. directly under the opened files (or whatever you call the tabs that are right about the red box in my image). I have no idea how to do this though, anyone have any suggestions?
Also, on a related note, when I do just open the type hierarchy it always requires that I open it given the context of the current opened .java file. On my other laptop it's sort of dynamic and allows me to explore the type hierarchy of whatever file I'm viewing. I want it all to work like how it is in Microsoft Visual Studio.
<IMAGE> | I think you mean the 'breadcrumb' - 'Navigate > Show in Breadcrumb' | |
15,626,302 | 1 | 18,218,235 | I recently made the switch from Eclipse to IntelliJ IDEA 12. Is there a good way to preview a fragment being used in another xml layout file?
In Eclipse there's a way to specify which fragment I'm using which is pretty helpful.
<IMAGE>
:
What I'm referring to is the ability to view a Fragment being referenced in another xml layout. Say I'm creating a Profile screen (activity_profile.xml) and want to include a fragment (fragment_pic.xml) that contains a picture, name, etc. When I include the fragment in the activity_profile.xml, it doesn't display in the preview for the activity_profile layout. It just displays "<fragment>" | You can do this in the XML:
'''
<fragment
android:name="com.yourpackage.yourapp.yourfragment"
android:layout_height="match_parent"
android:layout_width="match_parent"
tools:layout="@layout/fragment_layout"
</fragment>
'''
The tools namespace is qualified by this in the top view, same as xmlns:android namespace qualifier:
'''
xmlns:tools="http://schemas.android.com/tools"
'''
I had this same issue as well after moving from Eclipse to the Android Studio Preview though thankfully Android Studio suggests you provide this in the XML when it checks your definitions, very handy :) |
