  • problem in adding image to the UIButton.

    - by monish
    Hi friends, I got an another problem in my application and I am wasting so much of time on that. Does pls anyone can help with this problem. Actually I had an Event and I should give rating for that event for that I wrote the code as: In CellForRowAtIndexPath......I had the code as: - (UITableViewCell *)tableView:(UITableView *)tv cellForRowAtIndexPath:(NSIndexPath *)indexPath { UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"MasterViewIdentifier"]; //UITableViewCell *cell = nil; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:@"MasterViewIdentifier"] autorelease]; cell.selectionStyle = UITableViewCellSelectionStyleNone; UIView* elementView = [[UIView alloc] initWithFrame:CGRectMake(20,170,320,280)]; elementView.tag = 0; elementView.backgroundColor=[UIColor clearColor]; [cell.contentView addSubview:elementView]; [elementView release]; } UIView* elementView = [cell.contentView viewWithTag:0]; elementView.backgroundColor=[UIColor clearColor]; for(UIView* subView in elementView.subviews) { [subView removeFromSuperview]; } if(indexPath.section == 8) { UIImage *whiteImg = [UIImage imageNamed:@"white_star.png"] ; UIImage *yellowImg = [UIImage imageNamed:@"yellow_Star.png"] ; UIButton *button1 = [[UIButton alloc]initWithFrame:CGRectMake(159, 15, 25, 20)]; [button1 addTarget:self action:@selector(buttonAction:) forControlEvents:UIControlEventTouchUpInside]; button1.tag = 1; UIButton *button2 = [[UIButton alloc]initWithFrame:CGRectMake(185, 15, 25, 20)]; [button2 addTarget:self action:@selector(buttonAction:) forControlEvents:UIControlEventTouchUpInside]; button2.tag = 2; UIButton *button3 = [[UIButton alloc]initWithFrame:CGRectMake(211, 15, 25, 20)]; [button3 addTarget:self action:@selector(buttonAction:) forControlEvents:UIControlEventTouchUpInside];

button5.tag = 5; if(event.eventRatings == 1) { [button1 setBackgroundImage:yellowImg forState:UIControlStateNormal]; [button2 setBackgroundImage:whiteImg forState:UIControlStateNormal]; [button3 setBackgroundImage:whiteImg forState:UIControlStateNormal]; [button4 setBackgroundImage:whiteImg forState:UIControlStateNormal]; [button5 setBackgroundImage:whiteImg forState:UIControlStateNormal]; } else if(event.eventRatings == 2) { [button1 setBackgroundImage:yellowImg forState:UIControlStateNormal];

[tableView reloadData]; } When I build the application in simlator of 3.1.2 O.S its working fine by displaying the star images. My porblem is when I build it in 3.1.2 O.S Device the images are not displaying.I checked the code for casesensitivity in file name and its gud but Im not gettig the images to display. Guys help me to solve this. Thank you, Monish Kumar.

  • IText can't keep rows together, second row spans multiple pages but won't stick with first row.

    - by J2SE31
    I am having trouble keeping my first and second rows of my main PDFPTable together using IText. My first row consists of a PDFPTable with some basic search criteria. My second row consists of a PdfPTable that contains all of the tabulated results. Everytime the tabulated results becomes too big and spans multiple pages, it is kicked to the second page automatically rather than showing up directly below the search criteria and then paging to the next page. How can I avoid this problem? I have tried using setSplitRows(false), but I simply get a blank document (see commented lines 117 and 170). How can I keep my tabulated data (second row) up on the first page?

  • Repeat row headers after Page Break

    - by klaus.fabian
    The lead developer of the FO engine send me by chance an email about a REALLY nice feature I did not know about. Did you ever encounter a long table with merged cells, where the merged cell went on to the next page? While column headers are by default repeated on the next page, row headers are not. Tables with group-left column and pivot tables are prime examples where this problem occurs. I have seen reports where merged cells could go over multiple pages and you would need to back to find the row header on previous pages. The BI Publisher RTF templates have a special tag you can added to a merged cell to repeat the contents after each page break. You just need to add the following (wordy) tag to the next merged table cell: true Example: 2nd page of report before adding the tag 2nd page of report after adding the tag. Thought you might want to know. Klaus

  • Alternative Grid Layout for Silverlight suggestion

    - by brainbox
    I've proposed a suggestion to create alternative grid layout for Silverlight. Please vote for it if also faced the same problems. As i write before current Silverlight Grid Layout breakes best practices of HTML and Adobe Flex Grid layouts. Current defention based approach have following disadvantages that makes xaml coding very hard: 1. It is very hard to create new row. In that case you should rewriteall Grid.Row and Grid.Columns for all rows inserted below.2. Defenitions are static by their nature and because of it, it isimpossible to use grid for dynamic forms. Currently even in toolkit DataFormMicrosoft is using StackPanel. But StackPanel is not designed for multicolumn layout that have dataform. Here is a sample code of AdobeFlex datagrid, which incorporates bestpractices of HTML. <mx:Grid id="myGrid">        <!-- Define Row 1. -->       <mx:GridRow id="row1">           <!-- Define the first cell of Row 1. -->           <mx:GridItem>               <mx:Button label="Button 1"/>           </mx:GridItem>           <!-- Define the second cell of Row 1. -->           <mx:GridItem>               <mx:Button label="2"/>           </mx:GridItem>           <!-- Define the third cell of Row 1. -->           <mx:GridItem>               <mx:Button label="Button 3"/>           </mx:GridItem>       </mx:GridRow>        <!-- Define Row 2. -->       <mx:GridRow id="row2">           <!-- Define a single cell to span three columns of Row 2. -->           <mx:GridItem colSpan="3" horizontalAlign="center">               <mx:Button label="Long-Named Button 4"/>           </mx:GridItem>       </mx:GridRow>        <!-- Define Row 3. -->       <mx:GridRow id="row3">           <!-- Define an empty first cell of Row 3. -->           <mx:GridItem/>           <!-- Define a cell to span columns 2 and 3 of Row 3. -->           <mx:GridItem colSpan="2" horizontalAlign="center">               <mx:Button label="Button 5"/>           </mx:GridItem>       </mx:GridRow>    </mx:Grid>

  • How to Highlight a Row in Excel Using Conditional Formatting

    - by Erez Zukerman
    Conditional formatting is an Excel feature you can use when you want to format cells based on their content. For example, you can have a cell turn red when it contains a number lower than 100. But how do you highlight an entire row? If you’ve never used Conditional Formatting before, you might want to look at Using Conditional Cell Formatting in Excel 2007. It’s one version back, but the interface really hasn’t changed much. But what if you wanted to highlight other cells based on a cell’s value? The screenshot above shows some codenames used for Ubuntu distributions. One of these is made up; when I entered “No” in the “Really” column, the entire row got different background and font colors. To see how this was done, read on.How To Make a Youtube Video Into an Animated GIFHTG Explains: What Are Character Encodings and How Do They Differ?How To Make Disposable Sleeves for Your In-Ear Monitors

  • XNA VertexBuffer.SetData performance suggestions

    - by CodeSpeaker
    I have a 3d world in a grid layout where each grid cell contains its separate vertex and index buffer for the mesh/terrain of that cell. When the player moves outside the boundaries of his cell, i dynamically load more cells in his walking direction based on his viewing distance. This triggers x number of vertex and indexbuffer initializations depending on how many cells that needs to be generated and causes the framerate to drop annoyingly during this time. The generation of terrain data is handled in a separate thread and runs smoothly. The vertex and index buffers are added during the update cycle of the game loop. I´ve tried batching the number of cells to be processed to avoid sending too much data at once into the buffers, which worked ok at a shorter viewing distance (about 9 cells to process), but not as well at greater distances with around 30 cells to process. Any idea how i can optimize this?

  • How to add or remove a value inside a table cell on selection / de-selection of checkbox of that row, trying to submit the value via Jquery?

    - by Raul
    Here is the table: <%= form_tag '', :id => "costs" do %> <table class="table table-bordered" id="service_cost"> <% @services.each do |service| %> <tbody> <tr> <td><%= check_box_tag :open_service, {}, false, :class => 'checkable' %></td> <td><%= service.phone %></td> <td><%= service.internet %></td> <td></td> <td></td> <td></td> <td></td> <td></td> <td><%= service.house_keeping %> </td> <td>0.0 </td> <td><%= service.laundry %></td> <td><%= text_field_tag "service_cost", service.total, :class => "input-small" %></td> </tr> <% end %> when the form gets submitted, the javascript gets into action: $("#costs").submit(function(){ formData=$("#costs").serializeArray(); processFormData(formData) return false; }); This ensures form submission on selecting the checkbox: $('.checkable').live('change', function() { $(this).parents('form:first').submit(); }); But, what I am looking for is adding or removing a cell value based on checkbox selection/de-selection and submitting it, kindly suggest a way to do it.

  • The Incremental Architect&rsquo;s Napkin - #5 - Design functions for extensibility and readability

    - by Ralf Westphal
    Originally posted on: http://geekswithblogs.net/theArchitectsNapkin/archive/2014/08/24/the-incremental-architectrsquos-napkin---5---design-functions-for.aspx The functionality of programs is entered via Entry Points. So what we´re talking about when designing software is a bunch of functions handling the requests represented by and flowing in through those Entry Points. Designing software thus consists of at least three phases: Analyzing the requirements to find the Entry Points and their signatures Designing the functionality to be executed when those Entry Points get triggered Implementing the functionality according to the design aka coding I presume, you´re familiar with phase 1 in some way. And I guess you´re proficient in implementing functionality in some programming language. But in my experience developers in general are not experienced in going through an explicit phase 2. “Designing functionality? What´s that supposed to mean?” you might already have thought. Here´s my definition: To design functionality (or functional design for short) means thinking about… well, functions. You find a solution for what´s supposed to happen when an Entry Point gets triggered in terms of functions. A conceptual solution that is, because those functions only exist in your head (or on paper) during this phase. But you may have guess that, because it´s “design” not “coding”. And here is, what functional design is not: It´s not about logic. Logic is expressions (e.g. +, -, && etc.) and control statements (e.g. if, switch, for, while etc.). Also I consider calling external APIs as logic. It´s equally basic. It´s what code needs to do in order to deliver some functionality or quality. Logic is what´s doing that needs to be done by software. Transformations are either done through expressions or API-calls. And then there is alternative control flow depending on the result of some expression. Basically it´s just jumps in Assembler, sometimes to go forward (if, switch), sometimes to go backward (for, while, do). But calling your own function is not logic. It´s not necessary to produce any outcome. Functionality is not enhanced by adding functions (subroutine calls) to your code. Nor is quality increased by adding functions. No performance gain, no higher scalability etc. through functions. Functions are not relevant to functionality. Strange, isn´t it. What they are important for is security of investment. By introducing functions into our code we can become more productive (re-use) and can increase evolvability (higher unterstandability, easier to keep code consistent). That´s no small feat, however. Evolvable code can hardly be overestimated. That´s why to me functional design is so important. It´s at the core of software development. To sum this up: Functional design is on a level of abstraction above (!) logical design or algorithmic design. Functional design is only done until you get to a point where each function is so simple you are very confident you can easily code it. Functional design an logical design (which mostly is coding, but can also be done using pseudo code or flow charts) are complementary. Software needs both. If you start coding right away you end up in a tangled mess very quickly. Then you need back out through refactoring. Functional design on the other hand is bloodless without actual code. It´s just a theory with no experiments to prove it. But how to do functional design? An example of functional design Let´s assume a program to de-duplicate strings. The user enters a number of strings separated by commas, e.g. a, b, a, c, d, b, e, c, a. And the program is supposed to clear this list of all doubles, e.g. a, b, c, d, e. There is only one Entry Point to this program: the user triggers the de-duplication by starting the program with the string list on the command line C:\>deduplicate "a, b, a, c, d, b, e, c, a" a, b, c, d, e …or by clicking on a GUI button. This leads to the Entry Point function to get called. It´s the program´s main function in case of the batch version or a button click event handler in the GUI version. That´s the physical Entry Point so to speak. It´s inevitable. What then happens is a three step process: Transform the input data from the user into a request. Call the request handler. Transform the output of the request handler into a tangible result for the user. Or to phrase it a bit more generally: Accept input. Transform input into output. Present output. This does not mean any of these steps requires a lot of effort. Maybe it´s just one line of code to accomplish it. Nevertheless it´s a distinct step in doing the processing behind an Entry Point. Call it an aspect or a responsibility - and you will realize it most likely deserves a function of its own to satisfy the Single Responsibility Principle (SRP). Interestingly the above list of steps is already functional design. There is no logic, but nevertheless the solution is described - albeit on a higher level of abstraction than you might have done yourself. But it´s still on a meta-level. The application to the domain at hand is easy, though: Accept string list from command line De-duplicate Present de-duplicated strings on standard output And this concrete list of processing steps can easily be transformed into code:static void Main(string[] args) { var input = Accept_string_list(args); var output = Deduplicate(input); Present_deduplicated_string_list(output); } Instead of a big problem there are three much smaller problems now. If you think each of those is trivial to implement, then go for it. You can stop the functional design at this point. But maybe, just maybe, you´re not so sure how to go about with the de-duplication for example. Then just implement what´s easy right now, e.g.private static string Accept_string_list(string[] args) { return args[0]; } private static void Present_deduplicated_string_list( string[] output) { var line = string.Join(", ", output); Console.WriteLine(line); } Accept_string_list() contains logic in the form of an API-call. Present_deduplicated_string_list() contains logic in the form of an expression and an API-call. And then repeat the functional design for the remaining processing step. What´s left is the domain logic: de-duplicating a list of strings. How should that be done? Without any logic at our disposal during functional design you´re left with just functions. So which functions could make up the de-duplication? Here´s a suggestion: De-duplicate Parse the input string into a true list of strings. Register each string in a dictionary/map/set. That way duplicates get cast away. Transform the data structure into a list of unique strings. Processing step 2 obviously was the core of the solution. That´s where real creativity was needed. That´s the core of the domain. But now after this refinement the implementation of each step is easy again:private static string[] Parse_string_list(string input) { return input.Split(',') .Select(s => s.Trim()) .ToArray(); } private static Dictionary<string,object> Compile_unique_strings(string[] strings) { return strings.Aggregate( new Dictionary<string, object>(), (agg, s) => { agg[s] = null; return agg; }); } private static string[] Serialize_unique_strings( Dictionary<string,object> dict) { return dict.Keys.ToArray(); } With these three additional functions Main() now looks like this:static void Main(string[] args) { var input = Accept_string_list(args); var strings = Parse_string_list(input); var dict = Compile_unique_strings(strings); var output = Serialize_unique_strings(dict); Present_deduplicated_string_list(output); } I think that´s very understandable code: just read it from top to bottom and you know how the solution to the problem works. It´s a mirror image of the initial design: Accept string list from command line Parse the input string into a true list of strings. Register each string in a dictionary/map/set. That way duplicates get cast away. Transform the data structure into a list of unique strings. Present de-duplicated strings on standard output You can even re-generate the design by just looking at the code. Code and functional design thus are always in sync - if you follow some simple rules. But about that later. And as a bonus: all the functions making up the process are small - which means easy to understand, too. So much for an initial concrete example. Now it´s time for some theory. Because there is method to this madness ;-) The above has only scratched the surface. Introducing Flow Design Functional design starts with a given function, the Entry Point. Its goal is to describe the behavior of the program when the Entry Point is triggered using a process, not an algorithm. An algorithm consists of logic, a process on the other hand consists just of steps or stages. Each processing step transforms input into output or a side effect. Also it might access resources, e.g. a printer, a database, or just memory. Processing steps thus can rely on state of some sort. This is different from Functional Programming, where functions are supposed to not be stateful and not cause side effects.[1] In its simplest form a process can be written as a bullet point list of steps, e.g. Get data from user Output result to user Transform data Parse data Map result for output Such a compilation of steps - possibly on different levels of abstraction - often is the first artifact of functional design. It can be generated by a team in an initial design brainstorming. Next comes ordering the steps. What should happen first, what next etc.? Get data from user Parse data Transform data Map result for output Output result to user That´s great for a start into functional design. It´s better than starting to code right away on a given function using TDD. Please get me right: TDD is a valuable practice. But it can be unnecessarily hard if the scope of a functionn is too large. But how do you know beforehand without investing some thinking? And how to do this thinking in a systematic fashion? My recommendation: For any given function you´re supposed to implement first do a functional design. Then, once you´re confident you know the processing steps - which are pretty small - refine and code them using TDD. You´ll see that´s much, much easier - and leads to cleaner code right away. For more information on this approach I call “Informed TDD” read my book of the same title. Thinking before coding is smart. And writing down the solution as a bunch of functions possibly is the simplest thing you can do, I´d say. It´s more according to the KISS (Keep It Simple, Stupid) principle than returning constants or other trivial stuff TDD development often is started with. So far so good. A simple ordered list of processing steps will do to start with functional design. As shown in the above example such steps can easily be translated into functions. Moving from design to coding thus is simple. However, such a list does not scale. Processing is not always that simple to be captured in a list. And then the list is just text. Again. Like code. That means the design is lacking visuality. Textual representations need more parsing by your brain than visual representations. Plus they are limited in their “dimensionality”: text just has one dimension, it´s sequential. Alternatives and parallelism are hard to encode in text. In addition the functional design using numbered lists lacks data. It´s not visible what´s the input, output, and state of the processing steps. That´s why functional design should be done using a lightweight visual notation. No tool is necessary to draw such designs. Use pen and paper; a flipchart, a whiteboard, or even a napkin is sufficient. Visualizing processes The building block of the functional design notation is a functional unit. I mostly draw it like this: Something is done, it´s clear what goes in, it´s clear what comes out, and it´s clear what the processing step requires in terms of state or hardware. Whenever input flows into a functional unit it gets processed and output is produced and/or a side effect occurs. Flowing data is the driver of something happening. That´s why I call this approach to functional design Flow Design. It´s about data flow instead of control flow. Control flow like in algorithms is of no concern to functional design. Thinking about control flow simply is too low level. Once you start with control flow you easily get bogged down by tons of details. That´s what you want to avoid during design. Design is supposed to be quick, broad brush, abstract. It should give overview. But what about all the details? As Robert C. Martin rightly said: “Programming is abot detail”. Detail is a matter of code. Once you start coding the processing steps you designed you can worry about all the detail you want. Functional design does not eliminate all the nitty gritty. It just postpones tackling them. To me that´s also an example of the SRP. Function design has the responsibility to come up with a solution to a problem posed by a single function (Entry Point). And later coding has the responsibility to implement the solution down to the last detail (i.e. statement, API-call). TDD unfortunately mixes both responsibilities. It´s just coding - and thereby trying to find detailed implementations (green phase) plus getting the design right (refactoring). To me that´s one reason why TDD has failed to deliver on its promise for many developers. Using functional units as building blocks of functional design processes can be depicted very easily. Here´s the initial process for the example problem: For each processing step draw a functional unit and label it. Choose a verb or an “action phrase” as a label, not a noun. Functional design is about activities, not state or structure. Then make the output of an upstream step the input of a downstream step. Finally think about the data that should flow between the functional units. Write the data above the arrows connecting the functional units in the direction of the data flow. Enclose the data description in brackets. That way you can clearly see if all flows have already been specified. Empty brackets mean “no data is flowing”, but nevertheless a signal is sent. A name like “list” or “strings” in brackets describes the data content. Use lower case labels for that purpose. A name starting with an upper case letter like “String” or “Customer” on the other hand signifies a data type. If you like, you also can combine descriptions with data types by separating them with a colon, e.g. (list:string) or (strings:string[]). But these are just suggestions from my practice with Flow Design. You can do it differently, if you like. Just be sure to be consistent. Flows wired-up in this manner I call one-dimensional (1D). Each functional unit just has one input and/or one output. A functional unit without an output is possible. It´s like a black hole sucking up input without producing any output. Instead it produces side effects. A functional unit without an input, though, does make much sense. When should it start to work? What´s the trigger? That´s why in the above process even the first processing step has an input. If you like, view such 1D-flows as pipelines. Data is flowing through them from left to right. But as you can see, it´s not always the same data. It get´s transformed along its passage: (args) becomes a (list) which is turned into (strings). The Principle of Mutual Oblivion A very characteristic trait of flows put together from function units is: no functional units knows another one. They are all completely independent of each other. Functional units don´t know where their input is coming from (or even when it´s gonna arrive). They just specify a range of values they can process. And they promise a certain behavior upon input arriving. Also they don´t know where their output is going. They just produce it in their own time independent of other functional units. That means at least conceptually all functional units work in parallel. Functional units don´t know their “deployment context”. They now nothing about the overall flow they are place in. They are just consuming input from some upstream, and producing output for some downstream. That makes functional units very easy to test. At least as long as they don´t depend on state or resources. I call this the Principle of Mutual Oblivion (PoMO). Functional units are oblivious of others as well as an overall context/purpose. They are just parts of a whole focused on a single responsibility. How the whole is built, how a larger goal is achieved, is of no concern to the single functional units. By building software in such a manner, functional design interestingly follows nature. Nature´s building blocks for organisms also follow the PoMO. The cells forming your body do not know each other. Take a nerve cell “controlling” a muscle cell for example:[2] The nerve cell does not know anything about muscle cells, let alone the specific muscel cell it is “attached to”. Likewise the muscle cell does not know anything about nerve cells, let a lone a specific nerve cell “attached to” it. Saying “the nerve cell is controlling the muscle cell” thus only makes sense when viewing both from the outside. “Control” is a concept of the whole, not of its parts. Control is created by wiring-up parts in a certain way. Both cells are mutually oblivious. Both just follow a contract. One produces Acetylcholine (ACh) as output, the other consumes ACh as input. Where the ACh is going, where it´s coming from neither cell cares about. Million years of evolution have led to this kind of division of labor. And million years of evolution have produced organism designs (DNA) which lead to the production of these different cell types (and many others) and also to their co-location. The result: the overall behavior of an organism. How and why this happened in nature is a mystery. For our software, though, it´s clear: functional and quality requirements needs to be fulfilled. So we as developers have to become “intelligent designers” of “software cells” which we put together to form a “software organism” which responds in satisfying ways to triggers from it´s environment. My bet is: If nature gets complex organisms working by following the PoMO, who are we to not apply this recipe for success to our much simpler “machines”? So my rule is: Wherever there is functionality to be delivered, because there is a clear Entry Point into software, design the functionality like nature would do it. Build it from mutually oblivious functional units. That´s what Flow Design is about. In that way it´s even universal, I´d say. Its notation can also be applied to biology: Never mind labeling the functional units with nouns. That´s ok in Flow Design. You´ll do that occassionally for functional units on a higher level of abstraction or when their purpose is close to hardware. Getting a cockroach to roam your bedroom takes 1,000,000 nerve cells (neurons). Getting the de-duplication program to do its job just takes 5 “software cells” (functional units). Both, though, follow the same basic principle. Translating functional units into code Moving from functional design to code is no rocket science. In fact it´s straightforward. There are two simple rules: Translate an input port to a function. Translate an output port either to a return statement in that function or to a function pointer visible to that function. The simplest translation of a functional unit is a function. That´s what you saw in the above example. Functions are mutually oblivious. That why Functional Programming likes them so much. It makes them composable. Which is the reason, nature works according to the PoMO. Let´s be clear about one thing: There is no dependency injection in nature. For all of an organism´s complexity no DI container is used. Behavior is the result of smooth cooperation between mutually oblivious building blocks. Functions will often be the adequate translation for the functional units in your designs. But not always. Take for example the case, where a processing step should not always produce an output. Maybe the purpose is to filter input. Here the functional unit consumes words and produces words. But it does not pass along every word flowing in. Some words are swallowed. Think of a spell checker. It probably should not check acronyms for correctness. There are too many of them. Or words with no more than two letters. Such words are called “stop words”. In the above picture the optionality of the output is signified by the astrisk outside the brackets. It means: Any number of (word) data items can flow from the functional unit for each input data item. It might be none or one or even more. This I call a stream of data. Such behavior cannot be translated into a function where output is generated with return. Because a function always needs to return a value. So the output port is translated into a function pointer or continuation which gets passed to the subroutine when called:[3]void filter_stop_words( string word, Action<string> onNoStopWord) { if (...check if not a stop word...) onNoStopWord(word); } If you want to be nitpicky you might call such a function pointer parameter an injection. And technically you´re right. Conceptually, though, it´s not an injection. Because the subroutine is not functionally dependent on the continuation. Firstly continuations are procedures, i.e. subroutines without a return type. Remember: Flow Design is about unidirectional data flow. Secondly the name of the formal parameter is chosen in a way as to not assume anything about downstream processing steps. onNoStopWord describes a situation (or event) within the functional unit only. Translating output ports into function pointers helps keeping functional units mutually oblivious in cases where output is optional or produced asynchronically. Either pass the function pointer to the function upon call. Or make it global by putting it on the encompassing class. Then it´s called an event. In C# that´s even an explicit feature.class Filter { public void filter_stop_words( string word) { if (...check if not a stop word...) onNoStopWord(word); } public event Action<string> onNoStopWord; } When to use a continuation and when to use an event dependens on how a functional unit is used in flows and how it´s packed together with others into classes. You´ll see examples further down the Flow Design road. Another example of 1D functional design Let´s see Flow Design once more in action using the visual notation. How about the famous word wrap kata? Robert C. Martin has posted a much cited solution including an extensive reasoning behind his TDD approach. So maybe you want to compare it to Flow Design. The function signature given is:string WordWrap(string text, int maxLineLength) {...} That´s not an Entry Point since we don´t see an application with an environment and users. Nevertheless it´s a function which is supposed to provide a certain functionality. The text passed in has to be reformatted. The input is a single line of arbitrary length consisting of words separated by spaces. The output should consist of one or more lines of a maximum length specified. If a word is longer than a the maximum line length it can be split in multiple parts each fitting in a line. Flow Design Let´s start by brainstorming the process to accomplish the feat of reformatting the text. What´s needed? Words need to be assembled into lines Words need to be extracted from the input text The resulting lines need to be assembled into the output text Words too long to fit in a line need to be split Does sound about right? I guess so. And it shows a kind of priority. Long words are a special case. So maybe there is a hint for an incremental design here. First let´s tackle “average words” (words not longer than a line). Here´s the Flow Design for this increment: The the first three bullet points turned into functional units with explicit data added. As the signature requires a text is transformed into another text. See the input of the first functional unit and the output of the last functional unit. In between no text flows, but words and lines. That´s good to see because thereby the domain is clearly represented in the design. The requirements are talking about words and lines and here they are. But note the asterisk! It´s not outside the brackets but inside. That means it´s not a stream of words or lines, but lists or sequences. For each text a sequence of words is output. For each sequence of words a sequence of lines is produced. The asterisk is used to abstract from the concrete implementation. Like with streams. Whether the list of words gets implemented as an array or an IEnumerable is not important during design. It´s an implementation detail. Does any processing step require further refinement? I don´t think so. They all look pretty “atomic” to me. And if not… I can always backtrack and refine a process step using functional design later once I´ve gained more insight into a sub-problem. Implementation The implementation is straightforward as you can imagine. The processing steps can all be translated into functions. Each can be tested easily and separately. Each has a focused responsibility. And the process flow becomes just a sequence of function calls: Easy to understand. It clearly states how word wrapping works - on a high level of abstraction. And it´s easy to evolve as you´ll see. Flow Design - Increment 2 So far only texts consisting of “average words” are wrapped correctly. Words not fitting in a line will result in lines too long. Wrapping long words is a feature of the requested functionality. Whether it´s there or not makes a difference to the user. To quickly get feedback I decided to first implement a solution without this feature. But now it´s time to add it to deliver the full scope. Fortunately Flow Design automatically leads to code following the Open Closed Principle (OCP). It´s easy to extend it - instead of changing well tested code. How´s that possible? Flow Design allows for extension of functionality by inserting functional units into the flow. That way existing functional units need not be changed. The data flow arrow between functional units is a natural extension point. No need to resort to the Strategy Pattern. No need to think ahead where extions might need to be made in the future. I just “phase in” the remaining processing step: Since neither Extract words nor Reformat know of their environment neither needs to be touched due to the “detour”. The new processing step accepts the output of the existing upstream step and produces data compatible with the existing downstream step. Implementation - Increment 2 A trivial implementation checking the assumption if this works does not do anything to split long words. The input is just passed on: Note how clean WordWrap() stays. The solution is easy to understand. A developer looking at this code sometime in the future, when a new feature needs to be build in, quickly sees how long words are dealt with. Compare this to Robert C. Martin´s solution:[4] How does this solution handle long words? Long words are not even part of the domain language present in the code. At least I need considerable time to understand the approach. Admittedly the Flow Design solution with the full implementation of long word splitting is longer than Robert C. Martin´s. At least it seems. Because his solution does not cover all the “word wrap situations” the Flow Design solution handles. Some lines would need to be added to be on par, I guess. But even then… Is a difference in LOC that important as long as it´s in the same ball park? I value understandability and openness for extension higher than saving on the last line of code. Simplicity is not just less code, it´s also clarity in design. But don´t take my word for it. Try Flow Design on larger problems and compare for yourself. What´s the easier, more straightforward way to clean code? And keep in mind: You ain´t seen all yet ;-) There´s more to Flow Design than described in this chapter. In closing I hope I was able to give you a impression of functional design that makes you hungry for more. To me it´s an inevitable step in software development. Jumping from requirements to code does not scale. And it leads to dirty code all to quickly. Some thought should be invested first. Where there is a clear Entry Point visible, it´s functionality should be designed using data flows. Because with data flows abstraction is possible. For more background on why that´s necessary read my blog article here. For now let me point out to you - if you haven´t already noticed - that Flow Design is a general purpose declarative language. It´s “programming by intention” (Shalloway et al.). Just write down how you think the solution should work on a high level of abstraction. This breaks down a large problem in smaller problems. And by following the PoMO the solutions to those smaller problems are independent of each other. So they are easy to test. Or you could even think about getting them implemented in parallel by different team members. Flow Design not only increases evolvability, but also helps becoming more productive. All team members can participate in functional design. This goes beyon collective code ownership. We´re talking collective design/architecture ownership. Because with Flow Design there is a common visual language to talk about functional design - which is the foundation for all other design activities.   PS: If you like what you read, consider getting my ebook “The Incremental Architekt´s Napkin”. It´s where I compile all the articles in this series for easier reading. I like the strictness of Function Programming - but I also find it quite hard to live by. And it certainly is not what millions of programmers are used to. Also to me it seems, the real world is full of state and side effects. So why give them such a bad image? That´s why functional design takes a more pragmatic approach. State and side effects are ok for processing steps - but be sure to follow the SRP. Don´t put too much of it into a single processing step. ? Image taken from www.physioweb.org ? My code samples are written in C#. C# sports typed function pointers called delegates. Action is such a function pointer type matching functions with signature void someName(T t). Other languages provide similar ways to work with functions as first class citizens - even Java now in version 8. I trust you find a way to map this detail of my translation to your favorite programming language. I know it works for Java, C++, Ruby, JavaScript, Python, Go. And if you´re using a Functional Programming language it´s of course a no brainer. ? Taken from his blog post “The Craftsman 62, The Dark Path”. ?

  • Image auto resizes in PdfPCell with iTextSharp

    - by Mladen Prajdic
    Hi, i'm having a weird problem with images in iTextSharp library. I'm adding the image to the PdfPCell and for some reason it gets scaled up. How do i keep it to original size? Here's the image of the PDF at 100% and the image in its original size opened in paint.net. I though that the images would be same when printed but the difference on the pic is the same on the printed version. Having to manually scale the image with ScaleXXX to get it to right seems a bit illogical and does not give a good result. So how do I put the image in its original size inside a PdfPCell of a table without having to scale it? Here's my code: private PdfPTable CreateTestPDF() { PdfPTable table = new PdfPTable(1); table.WidthPercentage = 100; Phrase phrase = new Phrase("MY TITLE", _font24Bold); table.AddCell(phrase); PdfPTable nestedTable = new PdfPTable(5); table.WidthPercentage = 100; Phrase cellText = new Phrase("cell 1", _font9BoldBlack); nestedTable.AddCell(cellText); cellText = new Phrase("cell 2", _font9BoldBlack); nestedTable.AddCell(cellText); cellText = new Phrase("cell 3", _font9BoldBlack); nestedTable.AddCell(cellText); iTextSharp.text.Image image = iTextSharp.text.Image.GetInstance(@"d:\MyPic.jpg"); image.Alignment = iTextSharp.text.Image.ALIGN_CENTER; PdfPCell cell = new PdfPCell(image); cell.HorizontalAlignment = PdfPCell.ALIGN_MIDDLE; nestedTable.AddCell(cell); cellText = new Phrase("cell 5", _font9BoldBlack); nestedTable.AddCell(cellText); nestedTable.AddCell(""); string articleInfo = "Test Text"; cellText = new Phrase(articleInfo, _font8Black); nestedTable.AddCell(cellText); nestedTable.AddCell(""); nestedTable.AddCell(""); nestedTable.AddCell(""); table.AddCell(nestedTable); SetBorderSizeForAllCells(table, iTextSharp.text.Rectangle.NO_BORDER); return table; } static BaseColor _textColor = new BaseColor(154, 154, 154); iTextSharp.text.Font _font8 = new iTextSharp.text.Font(iTextSharp.text.Font.FontFamily.HELVETICA, 8, iTextSharp.text.Font.NORMAL, _textColor); iTextSharp.text.Font _font8Black = new iTextSharp.text.Font(iTextSharp.text.Font.FontFamily.HELVETICA, 8, iTextSharp.text.Font.NORMAL, BaseColor.BLACK); iTextSharp.text.Font _font9 = new iTextSharp.text.Font(iTextSharp.text.Font.FontFamily.HELVETICA, 9, iTextSharp.text.Font.NORMAL, _textColor); iTextSharp.text.Font _font9BoldBlack = new iTextSharp.text.Font(iTextSharp.text.Font.FontFamily.HELVETICA, 9, iTextSharp.text.Font.BOLD, BaseColor.BLACK); iTextSharp.text.Font _font10 = new iTextSharp.text.Font(iTextSharp.text.Font.FontFamily.HELVETICA, 10, iTextSharp.text.Font.NORMAL, _textColor); iTextSharp.text.Font _font10Black = new iTextSharp.text.Font(iTextSharp.text.Font.FontFamily.HELVETICA, 10, iTextSharp.text.Font.NORMAL, BaseColor.BLACK); iTextSharp.text.Font _font10BoldBlack = new iTextSharp.text.Font(iTextSharp.text.Font.FontFamily.HELVETICA, 10, iTextSharp.text.Font.BOLD, BaseColor.BLACK); iTextSharp.text.Font _font24Bold = new iTextSharp.text.Font(iTextSharp.text.Font.FontFamily.HELVETICA, 24, iTextSharp.text.Font.BOLD, _textColor);

  • UITableViewCell with custom gradient background, with another gradient as highlight color

    - by Rich
    I have a custom UITableViewCell with a custom layout. I wanted a gradient background, so in my UITableViewDelegate cellForRowAtIndexPath: method, I create a CAGradientLayer and add it to the cell's layer with insertSubLayer:atIndex: (using index 0). This works just fine except for two things: Most importantly, I can't figure out how to change to a different gradient color when the row is highlighted. I have tried a couple things, but I'm just not familiar enough with the framework to get it working. Where would be the ideal place to put that code, inside the table delegate or the cell itself? Also, there's a 1px white space in between each cell in the table. I have a background color on the main view, a background color on the table, and a background color on the cell. Is there some kind of padding or spacer by default in a UITableView?

  • UITableView UITableViewCell not reloading on reloadData

    - by David van Dugteren
    This question has been asked a few times now, but there exists no answer on the web that has solved the problem for me yet... See the code: { const NSInteger TOP_LABEL_TAG = 1001; static NSString *CellIdentifier = @"CellIdentifier"; UITableViewCell *cell = [theTableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease]; } getAQuestionToAnswer = [[QuestionsToAnswer sharedInstance] getLatestLoadedQuestion]; UILabel *topLabel; topLabel = [[[UILabel alloc] initWithFrame: CGRectMake ( 50, 18, 260, 75)] autorelease]; [cell.contentView addSubview:topLabel]; topLabel.tag = TOP_LABEL_TAG; topLabel.backgroundColor = [UIColor clearColor]; topLabel.textColor = [UIColor colorWithRed:0.25 green:0.0 blue:0.0 alpha:1.0]; topLabel.highlightedTextColor = [UIColor colorWithRed:1.0 green:1.0 blue:0.9 alpha:1.0]; [topLabel setFont:[UIFont fontWithName:@"MarkerFelt-Thin" size:13]]; topLabel.numberOfLines = 4; topLabel = (UILabel *)[cell viewWithTag:TOP_LABEL_TAG]; topLabel.text = [NSString stringWithFormat:@"%@", [getAQuestionToAnswer valueForKey:@"question"] ]; Some code is omitted but the basics is there, I'm updating by means of a shake gesture, the NSLog confirms that the getAQuestionToAnswer is indeed updated with a new question after the gesture. Yet at run time, no matter what I do... e.g. [self.tableview reloaddata]; nothing works. It just doesn't want to refresh.

  • UITableView issue when using separate delegate/dataSource

    - by Adam Alexander
    General Description: To start with what works, I have a UITableView which has been placed onto an Xcode-generated view using Interface Builder. The view's File Owner is set to an Xcode-generated subclass of UIViewController. To this subclass I have added working implementations of numberOfSectionsInTableView: tableView:numberOfRowsInSection: and tableView:cellForRowAtIndexPath: and the Table View's dataSource and delegate are connected to this class via the File Owner in Interface Builder. The above configuration works with no problems. The issue occurs when I want to move this Table View's dataSource and delegate implementations out to a separate class, most likely because there are other controls on the View besides the Table View and I'd like to move the Table View-related code out to its own class. To accomplish this, I try the following: Create a new subclass of UITableViewController in Xcode Move the known-good implementations of numberOfSectionsInTableView: tableView:numberOfRowsInSection: and tableView:cellForRowAtIndexPath: to the new subclass Drag a Table View Controller to the top level of the existing XIB in InterfaceBuilder, delete the View/TableView that are automatically created for this Table View Controller, then set the Table View Controller's class to match the new subclass Remove the previously-working Table View's existing dataSource and delegate connections and connect them to the new Table View Controller When complete, I do not have a working Table View. I end up with one of three outcomes which can seemingly happen at random: When the Table View loads, I get a runtime error indicating I am sending tableView:cellForRowAtIndexPath: to an object which does not recognize it When the Table View loads, the project breaks into the debugger without error There is no error, but the Table View does not appear With some debugging and having created a basic project just to reproduce this issue, I am usually seeing the 3rd option above (no error but no visible table view). I added some NSLog calls and found that although numberOfSectionsInTableView and numberOfRowsInSection are both getting called, cellForRowAtIndexPath is not. I am convinced I'm missing something really simple and was hoping the answer may be obvious to someone with more experience than I have. If this doesn't turn out to be an easy answer I would be happy to update with some code or a sample project. Thanks for your time! Complete steps to reproduce: Create a new iPhone OS, View-Based Application in Xcode and call it TableTest Open TableTestViewController.xib in Interface Builder and drag a Table View onto the provided view surface. Connect the Table View's dataSource and delegate outlets to File's Owner, which should already represent the TableTestViewController class. Save your changes Back in Xcode, add the following code to TableTestViewController.m: - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView { NSLog(@"Returning num sections"); return 1; } - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { NSLog(@"Returning num rows"); return 1; } - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { NSLog(@"Trying to return cell"); static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:CellIdentifier] autorelease]; } cell.text = @"Hello"; NSLog(@"Returning cell"); return cell; } Build and Go, and you should see the word Hello appear in the TableView Now to attempt to move this TableView's logic out to a separate class, first create a new file in Xcode, choosing UITableViewController subclass and calling the class TableTestTableViewController Remove the above code snippet from TableTestViewController.m and place it into TableTestTableViewController.m, replacing the default implementation of these three methods with ours. Back in Interface Builder within the same TableTestViewController.xib file, drag a Table View Controller into the main IB window and delete the new Table View object that automatically came with it Set the class for this new Table View Controller to TableTestTableViewController Remove the dataSource and delegate bindings from the existing, previously-working Table View and reconnect the same two bindings to the new Table Test Table View Controller we created. Save changes, Build and Go, and if you're getting the results I'm getting, note the Table View no longer functions properly Solution: With some more troubleshooting and some assistance from the iPhone Developer Forums at https://devforums.apple.com/message/5453, I've documented a solution! The main UIViewController subclass of the project needs an outlet pointing to the UITableViewController instance. To accomplish this, simply add the following to the primary view's header (TableTestViewController.h): #import "TableTestTableViewController.h" and IBOutlet TableTestTableViewController *myTableViewController; Then, in Interface Builder, connect the new outlet from File's Owner to Table Test Table View Controller in the main IB window. No changes are necessary in the UI part of the XIB. Simply having this outlet in place, even though no user code directly uses it, resolves the problem completely. Thanks to those who've helped and credit goes to BaldEagle on the iPhone Developer Forums for finding the solution.

  • How to insert a date to an Open XML worksheet?

    - by Manuel
    I'm using Microsoft Open XML SDK 2 and I'm having a really hard time inserting a date into a cell. I can insert numbers without a problem by setting Cell.DataType = CellValues.Number, but when I do the same with a date (Cell.DataType = CellValues.Date) Excel 2010 crashes (2007 too). I tried setting the Cell.Text value to many date formats as well as Excel's date/numeric format to no avail. I also tried to use styles, removing the type attribute, plus many other pizzas I threw at the wall... Can anyone point me to an example inserting a date to a worksheet? Thanks,

  • jQuery: shorten string length to fit a set width.

    - by Marius
    Hello there, I have a table, and in each cell I want to place strings, but they are much wider than the cell width. To prevent line break, I would like to shorten the strings to fit the cell, and append '...' at end to indicate that the string is much longer. The table has about 40 rows and has to be done to each cell, so its important that its a quick. Should I use JS/jQuery for this? How would I do it? Thank you for your time. Kind regards, Marius

    Hi All, Is it possible to hyperlink a url in excel automatically. I mean when the cell starts with something like http or www can I hyperlink that. Currently, I have to hit enter in the cell value in the formula bar to make the link as clickable. Also if I change the value in the cell, the link doesnt get refreshed until I hit enter. Is there a way in excel where it will automatically detect and apply a hyperlink.

  • UITableView not reloading data on [self.tableView reloadData]

    - by donnib
    I have following code : - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { NSUInteger row = [indexPath row]; static NSString *RowListCellIdentifier = @"RowListCellIdentifier"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:RowListCellIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:RowListCellIdentifier]autorelease]; } NSMutableString *rowString = [[NSMutableString alloc] init]; [rowString appendString:[[[rows objectAtIndex:row] firstNumber]stringValue]]; [rowString appendString:@" : "]; [rowString appendString:[[[rows objectAtIndex:row] secondNumber]stringValue]]; [rowString appendString:@" : "]; [[cell textLabel] setText:rowString]; [rowString release]; return cell; } - (void)viewWillAppear:(BOOL)animated { [self.tableView reloadData]; [super viewWillAppear:animated]; } My problem is that the textLabel does not get reloaded with new data. If i log the rowString i see the correct value so data is good but in the UI it's the old data. I can see the cellForRowAtIndexPath beeing called so i know the reloadDatacall goes thru. What am i doing wrong ?

  • Why won't my UISearchDisplayController fire the didSelectRowAtIndexPath moethod?

    - by John Wells
    I am having an odd problem when searching a UITableView using a UISearchDisplayController. The UITableViewController is a subclass of another UITableViewController with a working didSelectRowAtIndexPath method. Without searching the controller handles selections fine, sending the superclass a didSelectRowAtIndexPath call, but if I select a cell when searching the superclass receives nothing but the cell is highlighted. Below is the code from my subclass. @implementation AdvancedViewController @synthesize searchDisplayController, dict, filteredList; - (void)viewDidLoad { [super viewDidLoad]; // Programmatically set up search bar UISearchBar *mySearchBar = [[UISearchBar alloc] init]; mySearchBar.delegate = self; [mySearchBar setAutocapitalizationType:UITextAutocapitalizationTypeNone]; [mySearchBar sizeToFit]; self.tableView.tableHeaderView = mySearchBar; // Programmatically set up search display controller searchDisplayController = [[UISearchDisplayController alloc] initWithSearchBar:mySearchBar contentsController:self]; [self setSearchDisplayController:searchDisplayController]; [searchDisplayController setDelegate:self]; [searchDisplayController setSearchResultsDataSource:self]; // Parse data from server NSData * jsonData = [NSData dataWithContentsOfURL:[NSURL URLWithString:url]]; NSArray * items = [[NSArray alloc] initWithArray:[[CJSONDeserializer deserializer] deserializeAsArray:jsonData error:nil]]; // Init variables dict = [[NSMutableDictionary alloc] init]; listIndex = [[NSMutableArray alloc] init]; fullList = [[NSMutableArray alloc] init]; filteredList = [[NSMutableArray alloc] init]; // Get each item and format it for the UI for(NSMutableArray * item in items) { // Get the first letter NSString * firstKey = [[[item objectAtIndex:0] substringWithRange:NSMakeRange(0,1)] uppercaseString]; // Put symbols and numbers in the same section if ([[firstKey stringByTrimmingCharactersInSet:[[NSCharacterSet letterCharacterSet] invertedSet]] isEqualToString:@""]) firstKey = @"#"; // If there isn't a section with this key if (![listIndex containsObject:firstKey]) { // Add the key to the index for faster access (because it's already sorted) [listIndex addObject:firstKey]; // Add the key to the unordered dictionary [dict setObject:[NSMutableArray array] forKey:firstKey]; } // Add the object to the dictionary [[dict objectForKey:firstKey] addObject:[[NSMutableDictionary alloc] initWithObjects:item forKeys:[NSArray arrayWithObjects:@"name", @"url", nil]]]; // Add the object to the list for simple searching [fullList addObject:[[NSMutableDictionary alloc] initWithObjects:item forKeys:[NSArray arrayWithObjects:@"name", @"url", nil]]]; } filteredList = [NSMutableArray arrayWithCapacity:[fullList count]]; } #pragma mark - #pragma mark Table view data source // Custom method for object oriented data access - (NSString *)tableView:(UITableView *)tableView dataForRowAtIndexPath:(NSIndexPath *)indexPath withKey:(NSString *)key { return (NSString *)((tableView == self.searchDisplayController.searchResultsTableView) ?

  • UIImages not displaying in TableView on iPhone, but working in Simulator

    - by Graeme
    Hi, I have a UITable View that displays an image in the left hand side of the table cell, and it works fine in the simulator. Only problem is, once I ran it on my device no images appear. It's just a blank white space. Have checked that images are added to resource folder for build (which they are) and that capitals etc. match (which they do). Any ideas? Thanks. Code to display images: cell.imageView.layer.masksToBounds = YES; cell.imageView.layer.cornerRadius = 5.0; UIImage *image = [UIImage imageNamed:[[dog types] stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]]];; if ( image ) { cell.imageView.image = [image imageScaledToSize:CGSizeMake(50, 50)]; }
