  • UITextView Delegate shouldChangeTextInRange (or any over) doesn't get called

    - by justas wza
    Hello, I need to track changes in my UITextView method (actianly for limiting number of lines), but none of UITextViewDelegate methods are being called when editing in UITextView begins. Not even - (void)textViewDidChange:(UITextView *)textView; I dont know what Im doing wrong I added UITextViewDelegate method to header file like that: @interface PirmasViewController : UIViewController <UITextViewDelegate, MFMa...... And I put any methods for tracking changes in my implementation file: - (void)textViewDidChange:(UITextView *)textView{NSLog(@"something changed");} - (BOOL)textView:(UITextView *)aTextView shouldChangeTextInRange:(NSRange)aRange replacementText:(NSString*)aText{ NSLog(@"something changed"); return YES; }` but no rezults.

  • How can I set partial text color in JTextArea

    - by ComputerJy
    I want to set color for specific lines in the text area. What I've found so far, was the following // Declarations private final DefaultStyledDocument document; private final MutableAttributeSet homeAttributeSet; private final MutableAttributeSet awayAttributeSet; // Usage in the form constructor jTextAreaLog.setDocument(document); homeAttributeSet = new SimpleAttributeSet(); StyleConstants.setForeground(homeAttributeSet, Color.blue); StyleConstants.setItalic(homeAttributeSet, true); awayAttributeSet = new SimpleAttributeSet(); StyleConstants.setForeground(awayAttributeSet, Color.red); // Setting the style of the last line final int start = jTextAreaLog.getLineStartOffset(jTextAreaLog.getLineCount() - 2); final int length = jTextAreaLog.getLineEndOffset(jTextAreaLog.getLineCount() - 1) - start; document.setCharacterAttributes(start, length, awayAttributeSet, true); But this is not working. What am I doing wrong?

  • How to specify custom Sass directory with sinatra

    - by yaya3
    Instead of serving my Sass files from the default 'views' directory I'd like to change this to /assets/sass The following attempts are in my main ruby root file in the app: Attempt 1 set :sass, Proc.new { File.join(root, "assets/sass") } get '/stylesheet.css' do sass :core end With this I get the following error: myapp.rb:17 NoMethodError: undefined method `merge' for "/Users/x/x/x/mysinatraapp/assets/sass":String Attempt 2 get '/stylesheet.css' do sass :'/assets/sass/core' end Attempt 3 get '/stylesheet.css' do sass :'/assets/sass/core' end Both return the following error: Errno::ENOENT: No such file or directory - ./views/assets/sass/core.sass Attempt 4 get '/stylesheet.css' do sass :'../assets/sass/core' end This works! however, there must be something along the lines of set :sass, Proc.new { File.join(root, "assets/sass") } that sets this up for me?

  • Is regex too slow? Real life examples where simple non-regex alternative is better

    - by polygenelubricants
    I've seen people here made comments like "regex is too slow!", or "why would you do something so simple using regex!" (and then present a 10+ lines alternative instead), etc. I haven't really used regex in industrial setting, so I'm curious if there are applications where regex is demonstratably just too slow, AND where a simple non-regex alternative exists that performs significantly (maybe even asymptotically!) better. Obviously many highly-specialized string manipulations with sophisticated string algorithms will outperform regex easily, but I'm talking about cases where a simple solution exists and significantly outperforms regex. What counts as simple is subjective, of course, but I think a reasonable standard is that if it uses only String, StringBuilder, etc, then it's probably simple.

  • Best practices for developing bigger applications on Android

    - by Janusz
    I've already written some small Android Applications, most of them in one Activity and nearly no data that should be persistent on the device. Now I'm writing an application that needs more Activities and I'm a bit puzzled about how to organize all this. My app will download some data parse it show it to the user and then show other activities depending on the data and the user interaction. Some of that data could be cached, some of it has to be downloaded every time. Some of that data should not be downloaded freshly at the moment the orientation changes, but it should on the moment the activity is created... Another thing I'm confused about are things like a httpClient. I now for example create a new httpclient for every activity, the same thing for locationlisteners. Are there books, a blogs or documentations with patterns, examples and advice on organizing larger apps build on android? Everything I found until now are get startet tutorials leaving me alone after 60 lines of code...

  • Transferring a flat file database to a MySQL database

    - by Jon
    I have a flat file database (yeah gross I know - the worst part is that it's 1.4GB), and I'm in the process of moving it to a MySQL database. The problem is that I'm not sure how to go about doing this - and I've checked through every related question on here but none relate to what I want to do, nor how my database is currently setup. My current flat file database is setup to where a normal MySQL row is its own file, and a MySQL table would be the directory. So for example if you have a user named Jon, there would be a file for the user in a directory named /members/. Within that file would be various information for the user including the users id, rank etc - all separated by tabs, all on separate lines (userid\t4). So here's an example user file: userid 4 notes staff notes: bla bla staff2 notes: bla bla bla username Example So how can I convert the above into their own rows and fields in MySQL? And if possible, could I do thousands of these files at once? Thanks.

    - by genesys
    Hi! I'm working on a game for the iPhone where I use the Oolong engine for rendering, and now I just tried to update my project to the newest version. However - now I get the following error when I try to compile: gcc-4.2 failed with exit code 1 in the build results I see in which cpp file the error happens, but I don't see any additional information. how can I get more info about what is going wrong in order to track down the problem? edit: after inspecting the compile output, i got the following lines, where the error occurs: {standard input}:61:selected processor does not support 'fmrx r0, fpscr' {standard input}:62:unshifted register required -- 'bic r0,r0,#0x00370000' ...somemorelines {standard input}:69:selected processor does not support 'fmxr fpscr,r0' this is some VFO code from one of the #include files. it works fine in the examples that come with the egnine. could there be something screwed up with my project settings? I compared them to the one of the example and they seem to be identical

  • Delete a line from a file in java

    - by dalton conley
    Ok, so I'm trying to delete lines from a text file with java. Currently the way I'm doing this, is I'm keep track of a line number and inputting an index. The index is the line I want deleted. So each time I read a new line of data I increment the line count. Now when I reach the line count that is the same index, I dont write the data to the temporary file. Now this works, but what if for example I'm working with huge files and I have to worry about memory restraints. How can I do this with.. file markers? For example.. place the file marker on the line I want to do delete. Then delete that line? Or is that just too much work?

  • Open Flash Chart on Zend MVC Error

    - by davykiash
    I recently downloaded the Open Flash Chart source code and I have intergrated it into my Zend MVC.Since I use the autoloader I have renamed my files and commented the "require_once" source lines. However when I try to load my chart <script type="text/javascript"> swfobject.embedSWF( "<?php echo $this->baseUrl() ?>/swf/open-flash-chart.swf", "my_chart", "550", "200", "9.0.0", "<?php echo $this->baseUrl() ?>/swf/expressInstall.swf", {"data-file":"<?php echo $this->baseUrl()?>/reportexpense/piechart/"} ); </script> it loads the "/data-files/y-axis-auto-steps.txt" instead and I cant figure out why. My controller returns the JSON string which I expect to be rendered. What am I missing?

  • What did I lose when I upgraded?

    - by Richard
    I upgraded my work box from Vista64 to Win7-64 by doing a format and reinstall. I kept backups of the project done in MS Visual Studio 2008 (Team). But now it won't compile. I am getting errors generated on lines in the MS created header files like "'_In_' not defined" etc. I know it is because I lost some compiler setting/directive. I was sure that the compiler settings would be in the project file; now I see that things like the include file directories, LIB files, etc. are not. [FYI: The project is a VB.NET GUI with VC++ DLL talking to a PIC24 micro over USB.] How do I most efficiently get my project back on the road to execution?

  • Microsoft Quotation

    - by Asad Jibran Ahmed
    I don't know if this is the right place to ask this question, but I honestly have exhausted my self searching for the last hour. I am looking for a quotation made about Microsofts software. It goes something along the lines of: "They may make 2nd grade crappy software, but by God they know how to design interfaces" It was by a somewhat popular open source personality about the lack of good interface design in open source software. Does any one know the exact quotation? It will be a great help if someone can point me in the right direction.

  • How to fill a webdynpro table binded to a BAPI initially?

    - by Philipp Andre
    Hello SAP-Gurus, im fairly new to webdynpro abap and have the following problem: I created a service returning a set of all existing customers. This function works well, if i test it in a litte program simply printing out the lines. now i created a webdynpro containing a table to display these customers. I also did the binding! AND it works, but only if an event fires the execute...function. What i need is kind of "execute initially", means that the function gets executed when the table initially loads. How can i do this? Best regards Philipp

  • How can I force my checkbox's text to not wrap?

    - by B. Clay Shannon
    This is what my LinearLayout (horizontal) row looks like: I want the text of the checkbox to be on one line; The buttons don't have to be that wide - they'll still have plenty of space with the checkbox text lengthened a bit. What in my XML: <LinearLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:orientation="horizontal"> <CheckBox android:id="@+id/ckbxAllow_New_Items" android:layout_width="0dip" android:layout_height="fill_parent" android:layout_weight="1" android:checked="true" android:text="@string/checkbox_Allow_New_Items" /> <Button android:id="@+id/btnOK" android:layout_width="0dip" android:layout_height="wrap_content" android:layout_weight="1" android:text="@string/button_OK" /> <Button android:id="@+id/btnCancel" android:layout_width="0dip" android:layout_height="wrap_content" android:layout_weight="1" android:text="@string/button_Cancel" /> </LinearLayout> ...needs to change in order to force my checkbox text not to wrap? UPDATE Following Der Golem's suggestion by adding this: android:lines="1" ...and also changing layout_weight for the checkbox from 1 to 2 (set to 1 for the buttons) gave me what I wanted:

  • Export a SQL database into a CSV file and use it with WEKA

    - by Simon
    How can I export a query result from a .sql database into a .csv file? I tried with SELECT * FROM players INTO OUTFILE 'players.csv' FIELDS TERMINATED BY ',' LINES TERMINATED BY ';';` and my .csv file is something like: p1,1,2,3 p2,1,4,5 But they are not in saparated columns, all are in 1 column. I tried to create a .csv file by myself just to try WEKA, something like: p1 1 2 3 p2 1 4 5 But WEKA recognizes p1 1 2 3 as a single attribute. So: how can I export correctly a table from a sql db to a csv file? And how can I use it with WEKA?

  • Does anyone know what these Oracle AQ JMS XA properties do?

    - by Alan Chan
    I'm using Oracle Advanced Queues via JMS from within Websphere App Server. Does anyone know what effect the following two properties have:- - oracle.jms.useEmulatedXA - oracle.jms.useNativeXA I have seen mentioned in some blogs and quick start guides, usually in sentences along the lines of "Add -Doracle.jms.useEmulatedXA=false -Doracle.jms.useNativeXA=true to the JAVA_PROPERTIES variable", without any explanation as to what they do:- e.g. http://biemond.blogspot.com/2008/11/using-aq-in-weblogic-103.html http://sqltech.cl/doc/oas10gR31/integrate.1013/b28994/adptr_aq.htm#CHDEADFB I'm curious as to what these two properties actually do, and what the implications of setting them are, even though they don't seem to have any affect on our app regardless of whether we set them or not. Googling hasn't given any answers, does anyone have any clue what they actually do?

  • ctypes and pointer manipulation

    - by Chris
    I am dealing with image buffers, and I want to be able to access data a few lines into my image for analysis with a c library. I have created my 8-bit pixel buffer in Python using create_string_buffer. Is there a way to get a pointer to a location within that buffer without re-creating a new buffer? My goal is to analyze and change data within that buffer in chunks, without having to do a lot of buffer creation and data copying. In this case, ultimately, the C library is doing all the manipulation of the buffer, so I don't actually have to change values within the buffer using Python. I just need to give my C function access to data within the buffer.

  • Emacs: annoying Flymake dialog box.

    - by baol
    Hello I have the following lines in my ~/.emacs.d/init.el (custom-set-variables '(flymake-allowed-file-name-masks (quote ( ("\\.cc\\'" flymake-simple-make-init) ("\\.cpp\\'" flymake-simple-make-init))))) (add-hook 'find-file-hook 'flymake-find-file-hook) When I open a cc/cpp file that has a Makefile with the following content in the same folder I get proper on-the-fly compilation and error reporting (Flymake will check the syntax and report errors and warnings during code editing) .PHONY: check-syntax check-syntax: $(CXX) -Wall -Wextra -pedantic -fsyntax-only $(CHK_SOURCES) The problem is that when I open a .cc file that has no corresponding Makefile i get an annoying dialog box that warns me about flymake being disabled for every file opened. Is there some hook I can use to disable that warning? Can you provide sample elisp code and explanation on how you found the proper hook?

  • WinForms Application Hangs

    - by Ram
    Hi, I have an application (ABC) that I developed and it as a windows application (.exe). It is by itself quite a big application referring a lot of dll's. However, now there is a requirement that demands that this application(ABC) be a part of an even larger application (XYZ). Hence, I had to change the project type of "ABC" from being a windows application to a class library, and by changing a few lines of code. My problem is that, ever since I started using ABC as part of XYZ, the application started hanging if I dint perform any operation on it for 10 to 15 mins... I do not have any problems while running it as a separate application. Any reasons why this might occur? Any suggestions would be really appreciated... Thanks, Ram

  • Rails fields_for :child_index option explanation

    - by Timothy
    I have been trying to create a complex form with many nested models, and make it dynamic. Now I found that making a nested model isn't difficult with accepts_nested_attributes_for, but making it nested and dynamic was seemingly impossible if there were multiple nested models. I came across http://github.com/ryanb/complex-form-examples/blob/master/app/helpers/application_helper.rb which does it very elegantly. Could anyone shed some light on lines 13 and 16? 13 form_builder.object.class.reflect_on_association(method).klass.new and 16 form_builder.fields_for(method, options[:object], :child_index => "new_#{method}") do |f| From intuition, line 13 instantiates a new object, but why must it do so many method calls? I couldn't find any documentation for the :child_index option on line 16. When the form is created, a very large number is used as an index for new models, whereas existing models are indexed by their id. How does this work?

  • How to draw a full ellipse in a StreamGeometry in WPF?

    - by romkyns
    The only method in a StreamGeometryContext that seems related to ellipses is the ArcTo method. Unfortunately it is heavily geared to joining lines rather than drawing ellipses. In particular, the position of the arc is determined by a starting and ending point. For a full ellipse the two coincide obviously, and the exact orientation becomes undefined. So far the best way of drawing an ellipse centered on 100,100 of size 10,10 that I found is like this: using (var ctx = geometry.Open()) { ctx.BeginFigure(new Point(100+5, 100), isFilled: true, isClosed: true); ctx.ArcTo( new Point(100 + 5*Math.Cos(0.01), 100 + 5*Math.Sin(0.01)), // need a small angle but large enough that the ellipse is positioned accurately new Size(10/2, 10/2), // docs say it should be 10,10 but in practice it appears that this should be half the desired width/height... 0, true, SweepDirection.Counterclockwise, true, true); } Which is pretty ugly, and also leaves a small "flat" area (although not visible at normal zoom levels). How else might I draw a full ellipse using StreamGeometryContext?

  • can JLabel have img tags

    Hi, I am trying to display a JLabel which has a few lines of text and an image as follows: String html = "<html> hello </br> <img src = \"/absolute/path/here\" height = \"30\" width =\"40\"/> </html>"; JLabel l = new JLabel(html); For the image all I get is a broken image, is it possible to nest img tags inside a JLabel? EDIT: I want to add multiple images to the JLabel so I don't think the use of an ImageIcon will do here. Thanks

  • Enumerator Implementation: Use struct or class?

    - by Hosam Aly
    I noticed that List<T> defines its enumerator as a struct, while ArrayList defines its enumerator as a class. What's the difference? If I am to write an enumerator for my class, which one would be preferable? EDIT: My requirements cannot be fulfilled using yield, so I'm implementing an enumerator of my own. That said, I wonder whether it would be better to follow the lines of List<T> and implement it as a struct.

  • Creating Zend_Form elements from row html

    - by P.M
    Hi there, I am having an issue with Zend_Form and your help will be appreciated. in fact I have a class to generate categories as options $categories = My_Util_Category::toHtmlSelect();//for simplicity I removed other lines this code generates <select> <option > root</option> <option> root / children</option> </select> On another hand, I use Zend_Form form to edit categories. The code looks like: $form = My_Form_Category( $data, $selectElements = array() ); which outputs a form, text field, a select box for parent categories and a submit button. How can I get 'select element' from $form, and replace it with row html 'select' generated with $categories any help, or link will be appreciated. Thanks.
