  • Google maps API : V2 : Custom infowindow with bindInfoWindowHtml

    - by PlanetUnknown
    The API documentation gave me hopes last night with "bindInfoWindowHtml". But it doesn't seem to replace the default infoWindow, even when you provide your own class etc. I have tried using other ideas like the labeledmarker. But it doesn't support draggable markers. Hence can't use it in my application. Here is the sample code which shows the info. window inside, the original bubble. Isn't there a way to override that window as well ! ` <style type="text/css"> .infoWindowCustomClass { width: 500px; height: 500px; background-color: #CAEE96; color: #666; } </style> <meta http-equiv="content-type" content="text/html; charset=utf-8"/> <title>Google Maps JavaScript API Example</title> <script src="http://maps.google.com/maps?file=api&amp;v=2&amp;sensor=false&amp;key="" type="text/javascript"></script> <script type="text/javascript"> function load() { if (GBrowserIsCompatible()) { // Create our "tiny" marker icon var blueIcon = new GIcon(G_DEFAULT_ICON); blueIcon.image = "http://www.google.com/intl/en_us/mapfiles/ms/micons/blue-dot.png"; // Set up our GMarkerOptions object markerOptions = { icon:blueIcon }; var map = new GMap2(document.getElementById("map")); map.setCenter(new GLatLng(33.968064,-83.377047), 13); markerOptions.title = "fart"; var point = new GLatLng(33.968064,-83.377047); var marker = new GMarker(point); var tempName = document.getElementById("infoWindowCustom"); marker.bindInfoWindowHtml(tempName); map.addOverlay(marker); } } </script>` And here is the DIV - <DIV id="infoWindowCustom" name="infoWindowCustom" class="infoWindowCustomClass"> Name : <TEXTAREA NAME="nameID" ID="nameID" ROWS="2" COLS="25"></TEXTAREA> Comments : <TEXTAREA NAME="commentsID" ID="commentsID" ROWS="4" COLS="25"></TEXTAREA> </DIV>

  • Deleting items from a ListView using a custom BaseAdapter

    - by HXCaine
    I am using a customised BaseAdapter to display items on a ListView. The items are just strings held in an ArrayList. The list items have a delete button on them (big red X), and I'd like to remove the item from the ArrayList, and notify the ListView to update itself. However, every implementation I've tried gets mysterious position numbers given to it, so for example clicking item 2's delete button will delete item 5's. It seems to be almost entirely random. One thing to note is that elements may be repeated, but must be kept in the same order. For example, I can have "Irish" twice, as elements 3 and 7. My code is below: private static class ViewHolder { TextView lang; int position; } public View getView(final int position, View convertView, ViewGroup parent) { ViewHolder holder; if (convertView == null) { convertView = mInflater.inflate(R.layout.language_link_row, null); holder = new ViewHolder(); holder.lang = (TextView)convertView.findViewById(R.id.language_link_text); holder.position = position; final ImageView deleteButton = (ImageView) convertView.findViewById(R.id.language_link_cross_delete); deleteButton.setOnClickListener(this); convertView.setTag(holder); deleteButton.setTag(holder); } else { holder = (ViewHolder) convertView.getTag(); } holder.lang.setText(mLanguages.get(position)); return convertView; } I later attempt to retrieve the deleted element's position by grabbing the tag, but it's always the wrong position in the list. There is no noticeable pattern to the position given here, it always seems random. // The delete button's listener public void onClick(View v) { ViewHolder deleteHolder = (ViewHolder) v.getTag(); int pos = deleteHolder.position; ... ... ... } I would be quite happy to just delete the item from the ArrayList and have the ListView update itself, but the position I'm getting is incorrect so I can't do that. Please note that I did, at first, have the deleteButton clickListener inside the getView method, and used 'position' to delete the value, but I had the same problem. Any suggestions appreciated, this is really irritating me.

  • CodeDOM: Adding DebuggerStepThroughAttribute to property

    - by Dont Ask
    I know how to add a DebuggerStepThroughAttribute to a method or a constructor, usually you add it to the CustomAttributes collection of a code member. But I don't see a way to do this for the setter and getter of a C# property, because neither of them provides this collection where you add the attributes. Does anyone have a clue?

  • Dashcode: How to create a custom/new Project Template?

    - by JJBigThoughts
    I'm trying to customize the javascript that Dashcode uses. So that I won't step on Apple's Project Templates, I want to make a custom project template that would appear as a choice after you click "New Project." I have been able to modify one of the existing templates (like, Custom, Browser, Utility, RSS, and Podcast). I can not, however, seem to add a new template to the list, like adding "JJ's Awesome New Cross Platform Template" as a choice. I have tried copying the directory Plugins/TemplateWebCustom.wdgtTemplate and changing in Custom's Info.plist file the com.apple.Dashcode.template.web.custom to, say com.apple.Dashcode.template.web.custom2 and in Resouces/project.plist updating the key value pair: TemplateIdentifier ==>com.apple.Dashcode.template.web.custom Is it possible to add a new Project Template? What the minimum steps? Thanks, JJ

  • .NET JIT Code Cache leaking?

    - by pitchfork
    We have a server component written in .Net 3.5. It runs as service on a Windows Server 2008 Standard Edition. It works great but after some time (days) we notice massive slowdowns and an increased working set. We expected some kind of memory leak and used WinDBG/SOS to analyze dumps of the process. Unfortunately the GC Heap doesn’t show any leak but we noticed that the JIT code heap has grown from 8MB after the start to more than 1GB after a few days. We don’t use any dynamic code generation techniques by our own. We use Linq2SQL which is known for dynamic code generation but we don’t know if it can cause such a problem. The main question is if there is any technique to analyze the dump and check where all this Host Code Heap blocks that are shown in the WinDBG dumps come from? [Update] In the mean time we did some more analysis and had Linq2SQL as probable suspect, especially since we do not use precompiled queries. The following example program creates exactly the same behaviour where more and more Host Code Heap blocks are created over time. using System; using System.Linq; using System.Threading; namespace LinqStressTest { class Program { static void Main(string[] args) { for (int i = 0; i < 100; ++ i) ThreadPool.QueueUserWorkItem(Worker); while(runs < 1000000) { Thread.Sleep(5000); } } static void Worker(object state) { for (int i = 0; i < 50; ++i) { using (var ctx = new DataClasses1DataContext()) { long id = rnd.Next(); var x = ctx.AccountNucleusInfos.Where(an => an.Account.SimPlayers.First().Id == id).SingleOrDefault(); } } var localruns = Interlocked.Add(ref runs, 1); System.Console.WriteLine("Action: " + localruns); ThreadPool.QueueUserWorkItem(Worker); } static Random rnd = new Random(); static long runs = 0; } } When we replace the Linq query with a precompiled one, the problem seems to disappear.

    I need to design a calendar control which should be added to our companie's application (I know there's already quite a lot calendar controls but I shall develop our own one...). How should I start, should I use a kind of table to display the days or should I completely draw my own grid? How can I do this (I do not need rdy-to-use code, I just need some ideas...)

  • Hotfixing Code running inside Web Container with Groovy

    - by raoulsson
    I have a webapp running that has a bug. I know how to fix it in the sources. However I cannot redeploy the app as I would have to take it offline to do so. (At least not right now). I now want to fix the code "at runtime". Surgery on the living object, so to speak. The app is implemented in Java and is build on top of Seam. I have added a Groovy Console to the app previous to the last release. (A way to run arbitrary code at runtime) The normal way of adding behaviour to a class with Groovy would be similar to this: String.metaClass.foo= { x -> x * x } println "anything".foo(3) This code added the method foo to java.lang.String and prints 9. I can do the same thing with classes running inside my webapp container. New instances will thereafter show the same behaviour: com.my.package.SomeService.metaClass.foo= { x -> x * x } def someService = new com.my.package.SomeService() println someService.foo(3) Works as excpected. All good so far. My problem is now that the container, the web framework, Seam in this case, has already instantiated and cached the classes that I would like to manipulate (that is change their behaviour to reflect my bug fix). Ideally this code would work: com.my.package.SomeService.metaClass.foo= { x -> x * x } def x = org.jboss.seam.Component.getInstance(com.my.package.SomeService) println x.foo(3) However the instantiation of SomeService has already happened and there is no effect. Thus I need a way to make my changes "sticky". Has the groovy magic gone after my script has been run? Well, after logging out and in again, I can run this piece of code and get the expected result: def someService = new com.my.package.SomeService() println someService.foo(3) So the foo method is still around and it looks like my change has been permanent... So I guess the question that remains is how to force Seam to re-instantiate all its components and/or how to permanently make the change on all living instances...?

  • iphone Odd Problem when using a custom cell

    - by Brodie4598
    Please note where I have the NSLOG. All it is displaying in the log is the first three items in the nameSection. After some testing, I discovered it is displaying how many keys there are because if I add a key to the plist, it will log a fourth item in log. nameSection should be an array of the strings that make up the key array in the plist file. the plist file has 3 dictionaries, each with several arrays of strings. The code picks the dictionary I am working with correctly, then should use the array names as sections in the table and the strings en each array as what to display in each cell. so if the dictionary i am working with has 3 arrays, NSLOG will display 3 strings from the first array: 2010-05-01 17:03:26.957 Checklists[63926:207] string0 2010-05-01 17:03:26.960 Checklists[63926:207] string1 2010-05-01 17:03:26.962 Checklists[63926:207] string2 then stop with: 2010-05-01 17:03:26.963 Checklists[63926:207] * Terminating app due to uncaught exception 'NSRangeException', reason: '* -[NSCFArray objectAtIndex:]: index (3) beyond bounds (3)' if i added an array to the dictionary, it log 4 items instead of 3. I hope this explanation makes sense... -(NSInteger)numberOfSectionsInTableView:(UITableView *)tableView{ return [keys count]; } -(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger) section { NSString *key = [keys objectAtIndex:section]; NSArray *nameSection = [names objectForKey:key]; return [nameSection count]; } -(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { NSUInteger section = [indexPath section]; NSString *key = [keys objectAtIndex: section]; NSArray *nameSection = [names objectForKey:key]; static NSString *SectionsTableIdentifier = @"SectionsTableIdentifier"; static NSString *ChecklistCellIdentifier = @"ChecklistCellIdentifier "; ChecklistCell *cell = (ChecklistCell *)[tableView dequeueReusableCellWithIdentifier: SectionsTableIdentifier]; if (cell == nil) { NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"ChecklistCell" owner:self options:nil]; for (id oneObject in nib) if ([oneObject isKindOfClass:[ChecklistCell class]]) cell = (ChecklistCell *)oneObject; } NSUInteger row = [indexPath row]; NSDictionary *rowData = [self.keys objectAtIndex:row]; NSString *tempString = [[NSString alloc]initWithFormat:@"%@",[nameSection objectAtIndex:row]]; NSLog(@"%@",tempString); cell.colorLabel.text = [tempArray objectAtIndex:0]; cell.nameLabel.text = [tempArray objectAtIndex:1]; return cell; return cell; } - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath]; if (cell.accessoryType == UITableViewCellAccessoryNone) { cell.accessoryType = UITableViewCellAccessoryCheckmark; } else if (cell.accessoryType == UITableViewCellAccessoryCheckmark) { cell.accessoryType = UITableViewCellAccessoryNone; } [tableView deselectRowAtIndexPath:indexPath animated:NO]; } -(NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section{ NSString *key = [keys objectAtIndex:section]; return key; }

  • Help me understand this C code

If you are getting the listview item why does the code set the parameters of the item being retrieved? If you already had the values there would be no need to retrieve them. Secondly near the comment "original" is the original line of code which will compile with a warning under embedded visual c++ 4.0, but if you copy the exact same code into visual studio 2008 it will not compile. Since I did not write any of this code, and am trying to learn, is it possible the original author made a mistake on this line? The *pRoot should point to HKEY type yet he is casting to an HTREEITEM type which should never work since the data types don't match?

  • Switch case assembly level code

    - by puffadder
    Hi All, I am programming C on cygwin windows. After having done a bit of C programming and getting comfortable with the language, I wanted to look under the hood and see what the compiler is doing for the code that I write. So I wrote down a code block containing switch case statements and converted them into assembly using: gcc -S foo.c Here is the C source: switch(i) { case 1: { printf("Case 1\n"); break; } case 2: { printf("Case 2\n"); break; } case 3: { printf("Case 3\n"); break; } case 4: { printf("Case 4\n"); break; } case 5: { printf("Case 5\n"); break; } case 6: { printf("Case 6\n"); break; } case 7: { printf("Case 7\n"); break; } case 8: { printf("Case 8\n"); break; } case 9: { printf("Case 9\n"); break; } case 10: { printf("Case 10\n"); break; } default: { printf("Nothing\n"); break; } } Now the resultant assembly for the same is: movl $5, -4(%ebp) cmpl $10, -4(%ebp) ja L13 movl -4(%ebp), %eax sall $2, %eax movl L14(%eax), %eax jmp *%eax .section .rdata,"dr" .align 4 L14: .long L13 .long L3 .long L4 .long L5 .long L6 .long L7 .long L8 .long L9 .long L10 .long L11 .long L12 .text L3: movl $LC0, (%esp) call _printf jmp L2 L4: movl $LC1, (%esp) call _printf jmp L2 L5: movl $LC2, (%esp) call _printf jmp L2 L6: movl $LC3, (%esp) call _printf jmp L2 L7: movl $LC4, (%esp) call _printf jmp L2 L8: movl $LC5, (%esp) call _printf jmp L2 L9: movl $LC6, (%esp) call _printf jmp L2 L10: movl $LC7, (%esp) call _printf jmp L2 L11: movl $LC8, (%esp) call _printf jmp L2 L12: movl $LC9, (%esp) call _printf jmp L2 L13: movl $LC10, (%esp) call _printf L2: Now, in the assembly, the code is first checking the last case (i.e. case 10) first. This is very strange. And then it is copying 'i' into 'eax' and doing things that are beyond me. I have heard that the compiler implements some jump table for switch..case. Is it what this code is doing? Or what is it doing and why? Because in case of less number of cases, the code is pretty similar to that generated for if...else ladder, but when number of cases increases, this unusual-looking implementation is seen. Thanks in advance.

  • Setting custom UITableViewCells height

    - by Vijayeta
    I am using a custum UITableViewCell , which has some labels , buttons imageviews to be displayed.There is one label in the cell whose text is a NSString object and the length of string could be variable , due to this i cannot set a constant height to the cell in UITableViews : heightForCellAtIndex method.The ceels height depends on the labels height , whcich can be determined using the NSStrings sizeWithFont method . i tried using it , but looks like i m going wrong somewhere . Can anyone help me out in this , adding the code used in iniatilizing the cell if (self = [super initWithFrame:frame reuseIdentifier:reuseIdentifier]) { self.selectionStyle = UITableViewCellSelectionStyleNone; UIImage *image = [UIImage imageNamed:@"dot.png"]; imageView = [[UIImageView alloc] initWithImage:image]; imageView.frame = CGRectMake(45.0,10.0,10,10); headingTxt = [[UILabel alloc] initWithFrame: CGRectMake(60.0,0.0,150.0,post_hdg_ht)]; [headingTxt setContentMode: UIViewContentModeCenter]; headingTxt.text = postData.user_f_name; headingTxt.font = [UIFont boldSystemFontOfSize:13]; headingTxt.textAlignment = UITextAlignmentLeft; headingTxt.textColor = [UIColor blackColor]; dateTxt = [[UILabel alloc] initWithFrame:CGRectMake(55.0,23.0,150.0,post_date_ht)]; dateTxt.text = postData.created_dtm; dateTxt.font = [UIFont italicSystemFontOfSize:11]; dateTxt.textAlignment = UITextAlignmentLeft; dateTxt.textColor = [UIColor grayColor]; NSString * text1 = postData.post_body; NSLog(@"text length = %d",[text1 length]); CGRect bounds = [UIScreen mainScreen].bounds; CGFloat tableViewWidth; CGFloat width = 0; tableViewWidth = bounds.size.width/2; width = tableViewWidth - 40; //fudge factor //CGSize textSize = {width, 20000.0f}; //width and height of text area CGSize textSize = {245.0, 20000.0f}; //width and height of text area CGSize size1 = [text1 sizeWithFont:[UIFont systemFontOfSize:11.0f] constrainedToSize:textSize lineBreakMode:UILineBreakModeWordWrap]; CGFloat ht = MAX(size1.height, 28); textView = [[UILabel alloc] initWithFrame:CGRectMake(55.0,42.0,245.0,ht)]; textView.text = postData.post_body; textView.font = [UIFont systemFontOfSize:11]; textView.textAlignment = UITextAlignmentLeft; textView.textColor = [UIColor blackColor]; textView.lineBreakMode = UILineBreakModeWordWrap; textView.numberOfLines = 3; textView.autoresizesSubviews = YES; [self.contentView addSubview:imageView]; [self.contentView addSubview:textView]; [self.contentView addSubview:webView]; [self.contentView addSubview:dateTxt]; [self.contentView addSubview:headingTxt]; [self.contentView sizeToFit]; [imageView release]; [textView release]; [webView release]; [dateTxt release]; [headingTxt release]; } textView = [[UILabel alloc] initWithFrame:CGRectMake(55.0,42.0,245.0,ht)]; this is the label whose height and widh are going wrong

  • ajaxSubmit and Other Code. Can someone help me determine what this code is doing?

    - by Matt Dawdy
    I've inherited some code that I need to debug. It isn't working at present. My task is to get it to work. No other requirements have been given to me. No, this isn't homework, this is a maintenance nightmare job. ASP.Net (framework 3.5), C#, jQury 1.4.2. This project makes heavy use of jQuery and AJAX. There is a drop down on a page that, when an item is chosen, is supposed to add that item (it's a user) to an object in the database. To accomplish this, the previous programmer first, on page load, dynamically loads the entire page through AJAX. To do this, he's got 5 div's, and each one is loaded from a jquery call to a different full page in the website. Somehow, the HTML and BODY and all the other stuff is stripped out and the contents of the div are loaded with the content of the aspx page. Which seems incredibly wrong to me since it relies on the browser to magically strip out html, head, body, form tags and merge with the existing html head body form tags. Also, as the "content" page is returned as a string, the previous programmer has this code running on it before it is appended to the div: function CleanupResponseText(responseText, uniqueName) { responseText = responseText.replace("theForm.submit();", "SubmitSubForm(theForm, $(theForm).parent());"); responseText = responseText.replace(new RegExp("theForm", "g"), uniqueName); responseText = responseText.replace(new RegExp("doPostBack", "g"), "doPostBack" + uniqueName); return responseText; } When the dropdown itself fires it's onchange event, here is the code that gets fired: function SubmitSubForm(form, container) { //ShowLoading(container); $(form).ajaxSubmit( { url: $(form).attr("action"), success: function(responseText) { $(container).html(CleanupResponseText(responseText, form.id)); $("form", container).css("margin-top", "0").css("padding-top", "0"); //HideLoading(container); } } ); } This blows up in IE, with the message that "Microsoft JScript runtime error: Object doesn't support this property or method" -- which, I think, has to be that $(form).ajaxSubmit method doesn't exist. What is this code really trying to do? I am so turned around right now that I think my only option is to scrap everything and start over. But I'd rather not do that unless necessary. Is this code good? Is it working against .Net, and is that why we are having issues?

  • How to uncheck header checkbox in GridView when sorting and paging?

    - by OutOFTouch
    Hi, I followed this article and it works great except when paging or sorting the HeaderCheckBox is still checked. How and where should this be unchecked? I think it would be best to uncheck it in the control itself, but I am not having any luck even getting a reference to it using this code: protected override void OnSorted(EventArgs e) { base.OnSorted(e); if (AutoGenerateCheckBoxColumn) { CheckBox cb = (CheckBox) HeaderRow.FindControl(String.Format(HeaderCheckBoxId, ClientID)); if(cb != null) { cb.Checked = false; } } } Thanks

In my output window. package { import flash.display.MovieClip; import flash.events.MouseEvent; import flash.events.KeyboardEvent; import flash.events.Event; import flash.ui.Keyboard; public class Code extends MovieClip { var charSpeed:int = 0; var velocity:int = 0; var gravity:Number = 1; var Jump:Boolean = false; public function startGame(){ stage.addEventListener(KeyboardEvent.KEY_DOWN, checkKeyDown); stage.addEventListener(KeyboardEvent.KEY_UP, checkKeyUp); stage.addEventListener(Event.ENTER_FRAME, loop); } private var platform:Platform; public function Code(value:Platform) { platform = value; } function checkKeyDown(evt:KeyboardEvent){ if (evt.keyCode == Keyboard.LEFT){ charSpeed -= 10; } if (evt.keyCode == Keyboard.RIGHT){ charSpeed += 10; } if (evt.keyCode == Keyboard.DOWN){ if(!Jump){ velocity -= 14; Jump = true; } } } function checkKeyUp(evt:KeyboardEvent){ if (evt.keyCode == Keyboard.LEFT){ charSpeed = 0; } if (evt.keyCode == Keyboard.RIGHT){ charSpeed = 0; } } function loop(evt:Event){ player.x = velocity; if (player.x < 0){ player.x = 0; } if (player.x > 550){ player.x = 550; } velocity += gravity; var Platform:Array = new Array(platform) if (!Platform.hitTestPoint(player.x, player.y, true)){ player.y += velocity; } for (var i = 0; i < 10; i++){ if (Platform.hitTestPoint(player.x, player.y, true)){ player.y--; velocity = 0; Jump = false; } } } } } The as3 file name is Code, and the fla file name is Game. My objective is to get my player to move around on the platform using the arrow keys. The linkage of my platform is "Platform". If anyone could help that would be great

  • Extending DataGrid/Changing DataGrids header

    - by drasto
    Is there any way how to override DataGrids header line ? Or at least its behaviour ? I'm trying to implement Outlook-like grouping of the table. That is allow user to drag column header out of the table to the dedicated area to sort by that column (for example XamDataGrid has that feature, you can see how it works here). I cannot use any commercial solutions. I will be thankfull for any experiences, ideas, code, notes or tutorials.

  • Extending struts 2 "property" data tag

    - by John B.
    Hi, We are currently developing a project with Struts2. We have a module on which we display a large amount of data on read-only fields from a group of beans via the "property" Struts 2 data tag (i.e. <s:property value="aBeanProperty" /) on a jsp file. In some cases most of the fields might come empty, so a blank is being displayed on screen. Our customer is now requesting us to display default string (i.e. "N/A") whenever a property comes empty, so that it is displayed in place of the blank spaces currently shown. We are looking for a way to achieve this in a clean and maintainable way. The 'property' tag comes with a 'default' attribute on which one can define a default value in cases when the accessed property comes as null. However, most of our properties are empty strings, therefore it does not work in our case. Another solution we are thinking of is to define a base class for all of our beans, and define a util method which will validate if a string is null or empty and then return the default value. Then we would call this method from each bean getter. And yes this would be tiresome and kind of ugly :), therefore we are holding out on this one in case of a better solution. Now, we have in mind a solution which we think would be the best but have not had luck on how implement it. We are planning on extending the 'property' tag some way, defining a new 'default' attribute so that besides working on null properties, it also do so on empty strings ("", " ", etc). Therefore we would only need to replace the original s:property tag with our new custom tag, and the desired result would be achieved without touching java code. Do you have an idea on how to do this? Also, any other clever solution (maybe some sort of design pattern?) on how to default the values of a large amount of property beans are welcome too! (Or maybe, even there might be some tag that does this already in Struts2??) Thanks in advance.

  • Is it feasible and useful to auto-generate some code of unit tests?

    - by skiwi
    Earlier today I have come up with an idea, based upon a particular real use case, which I would want to have checked for feasability and usefulness. This question will feature a fair chunk of Java code, but can be applied to all languages running inside a VM, and maybe even outside. While there is real code, it uses nothing language-specific, so please read it mostly as pseudo code. The idea Make unit testing less cumbersome by adding in some ways to autogenerate code based on human interaction with the codebase. I understand this goes against the principle of TDD, but I don't think anyone ever proved that doing TDD is better over first creating code and then immediatly therafter the tests. This may even be adapted to be fit into TDD, but that is not my current goal. To show how it is intended to be used, I'll copy one of my classes here, for which I need to make unit tests. public class PutMonsterOnFieldAction implements PlayerAction { private final int handCardIndex; private final int fieldMonsterIndex; public PutMonsterOnFieldAction(final int handCardIndex, final int fieldMonsterIndex) { this.handCardIndex = Arguments.requirePositiveOrZero(handCardIndex, "handCardIndex"); this.fieldMonsterIndex = Arguments.requirePositiveOrZero(fieldMonsterIndex, "fieldCardIndex"); } @Override public boolean isActionAllowed(final Player player) { Objects.requireNonNull(player, "player"); Hand hand = player.getHand(); Field field = player.getField(); if (handCardIndex >= hand.getCapacity()) { return false; } if (fieldMonsterIndex >= field.getMonsterCapacity()) { return false; } if (field.hasMonster(fieldMonsterIndex)) { return false; } if (!(hand.get(handCardIndex) instanceof MonsterCard)) { return false; } return true; } @Override public void performAction(final Player player) { Objects.requireNonNull(player); if (!isActionAllowed(player)) { throw new PlayerActionNotAllowedException(); } Hand hand = player.getHand(); Field field = player.getField(); field.setMonster(fieldMonsterIndex, (MonsterCard)hand.play(handCardIndex)); } } We can observe the need for the following tests: Constructor test with valid input Constructor test with invalid inputs isActionAllowed test with valid input isActionAllowed test with invalid inputs performAction test with valid input performAction test with invalid inputs My idea mainly focuses on the isActionAllowed test with invalid inputs. Writing these tests is not fun, you need to ensure a number of conditions and you check whether it really returns false, this can be extended to performAction, where an exception needs to be thrown in that case. The goal of my idea is to generate those tests, by indicating (through GUI of IDE hopefully) that you want to generate tests based on a specific branch. The implementation by example User clicks on "Generate code for branch if (handCardIndex >= hand.getCapacity())". Now the tool needs to find a case where that holds. (I haven't added the relevant code as that may clutter the post ultimately) To invalidate the branch, the tool needs to find a handCardIndex and hand.getCapacity() such that the condition >= holds. It needs to construct a Player with a Hand that has a capacity of at least 1. It notices that the capacity private int of Hand needs to be at least 1. It searches for ways to set it to 1. Fortunately it finds a constructor that takes the capacity as an argument. It uses 1 for this. Some more work needs to be done to succesfully construct a Player instance, involving the creation of objects that have constraints that can be seen by inspecting the source code. It has found the hand with the least capacity possible and is able to construct it. Now to invalidate the test it will need to set handCardIndex = 1. It constructs the test and asserts it to be false (the returned value of the branch) What does the tool need to work? In order to function properly, it will need the ability to scan through all source code (including JDK code) to figure out all constraints. Optionally this could be done through the javadoc, but that is not always used to indicate all constraints. It could also do some trial and error, but it pretty much stops if you cannot attach source code to compiled classes. Then it needs some basic knowledge of what the primitive types are, including arrays. And it needs to be able to construct some form of "modification trees". The tool knows that it needs to change a certain variable to a different value in order to get the correct testcase. Hence it will need to list all possible ways to change it, without using reflection obviously. What this tool will not replace is the need to create tailored unit tests that tests all kinds of conditions when a certain method actually works. It is purely to be used to test methods when they invalidate constraints. My questions: Is creating such a tool feasible? Would it ever work, or are there some obvious problems? Would such a tool be useful? Is it even useful to automatically generate these testcases at all? Could it be extended to do even more useful things? Does, by chance, such a project already exist and would I be reinventing the wheel? If not proven useful, but still possible to make such thing, I will still consider it for fun. If it's considered useful, then I might make an open source project for it depending on the time. For people searching more background information about the used Player and Hand classes in my example, please refer to this repository. At the time of writing the PutMonsterOnFieldAction has not been uploaded to the repo yet, but this will be done once I'm done with the unit tests.

  • CA2000 passing object reference to base constructor in C#

    - by Timothy
    I receive a warning when I run some code through Visual Studio's Code Analysis utility which I'm not sure how to resolve. Perhaps someone here has come across a similar issue, resolved it, and is willing to share their insight. I'm programming a custom-painted cell used in a DataGridView control. The code resembles: public class DataGridViewMyCustomColumn : DataGridViewColumn { public DataGridViewMyCustomColumn() : base(new DataGridViewMyCustomCell()) { } It generates the following warning: CA2000 : Microsoft.Reliability : In method 'DataGridViewMyCustomColumn.DataGridViewMyCustomColumn()' call System.IDisposable.Dispose on object 'new DataGridViewMyCustomCell()' before all references to it are out of scope. I understand it is warning me DataGridViewMyCustomCell (or a class that it inherits from) implements the IDisposable interface and the Dispose() method should be called to clean up any resources claimed by DataGridViewMyCustomCell when it is no longer. The examples I've seen on the internet suggest a using block to scope the lifetime of the object and have the system automatically dispose it, but base isn't recognized when moved into the body of the constructor so I can't write a using block around it... which I'm not sure I'd want to do anyway, since wouldn't that instruct the run time to free the object which could still be used later inside the base class? My question then, is the code okay as is? Or, how could it be refactored to resolve the warning? I don't want to suppress the warning unless it is truly appropriate to do so.

  • How to extract $lastexitcode from c# powershell script execution.

    - by scope-creep
    Hi, I've got a scipt executing in C# using the powershell async execution code on code project here: http://www.codeproject.com/KB/threads/AsyncPowerShell.aspx?display=PrintAll&fid=407636&df=90&mpp=25&noise=3&sort=Position&view=Quick&select=2130851#xx2130851xx I need to return the $lastexitcode and Jean-Paul describes how you can use a custom pshost class to return it. I can't find any method or property in pshost that returns the exit code. This engine I have needs to ensure that script executes correctly. Any help would be appreciated. regards Bob. Its the $lastexitcode and the $? variables I need to bring back. Hi, Finally answered. I found out about the $host variable. It implements a callback into the host, specifically a custom PSHost object, enabling you to return the $lastexitcode. Here is a link to an explanation of $host. http://mshforfun.blogspot.com/2006/08/do-you-know-there-is-host-variable.html It seems to be obscure, badly documented, as usual with powershell docs. Using point 4, calling $host.SetShouldExit(1) returns 1 to the SetShouldExit method of pshost, as described here. http://msdn.microsoft.com/en-us/library/system.management.automation.host.pshost.setshouldexit(VS.85).aspx Its really depends on defining your own exit code defintion. 0 and 1 suffixes I guess. regards Bob.

  • iPhone - archiving array of custom objects

    - by Dylan
    I've been trying for hours and I cannot solve this problem. I'm making an app that saves unfinished Chess Games, so I'm trying to write an array to a file. This is what the array is, if it makes sense: -NSMutableArray savedGames --GameSave a ---NSMutableArray board; ----Piece a, b, c, etc. -----some ints ---NSString whitePlayer, blackPlayer; ---int playerOnTop, turn; --GameSave b ---NSMutableArray board; ----Piece a, b, c, etc. -----some ints ---NSString whitePlayer, blackPlayer; ---int playerOnTop, turn; etc. And these are my NSCoding methods: GameSave.m - (void)encodeWithCoder:(NSCoder *)coder { [coder encodeObject:whitePlayer forKey:@"whitePlayer"]; [coder encodeObject:blackPlayer forKey:@"blackPlayer"]; [coder encodeInt:playerOnTop forKey:@"playerOnTop"]; [coder encodeInt:turn forKey:@"turn"]; [coder encodeObject:board forKey:@"board"]; } - (id)initWithCoder:(NSCoder *)coder { self = [[GameSave alloc] init]; if (self != nil) { board = [coder decodeObjectForKey:@"board"]; whitePlayer = [coder decodeObjectForKey:@"whitePlayer"]; blackPlayer = [coder decodeObjectForKey:@"blackPlayer"]; playerOnTop = [coder decodeIntForKey:@"playerOnTop"]; turn = [coder decodeIntForKey:@"turn"]; } return self; } Piece.m - (void)encodeWithCoder:(NSCoder *)coder { [coder encodeInt:color forKey:@"color"]; [coder encodeInt:piece forKey:@"piece"]; [coder encodeInt:row forKey:@"row"]; [coder encodeInt:column forKey:@"column"]; } - (id)initWithCoder:(NSCoder *)coder { self = [[Piece alloc] init]; if (self != nil) { color = [coder decodeIntForKey:@"color"]; piece = [coder decodeIntForKey:@"piece"]; row = [coder decodeIntForKey:@"row"]; column = [coder decodeIntForKey:@"column"]; } return self; } And this is the code that tries to archive and save to file: - (void)saveGame { ChessSaverAppDelegate *delegate = (ChessSaverAppDelegate *) [[UIApplication sharedApplication] delegate]; [[delegate gameSave] setBoard:board]; NSMutableArray *savedGames = [NSKeyedUnarchiver unarchiveObjectWithFile:[self dataFilePath]]; if (savedGames == nil) { [NSKeyedArchiver archiveRootObject:[delegate gameSave] toFile:[self dataFilePath]]; } else { [savedGames addObject:[delegate gameSave]]; [NSKeyedArchiver archiveRootObject:savedGames toFile:[self dataFilePath]]; } } - (NSString *)dataFilePath { NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *documentsDirectory = [paths objectAtIndex:0]; return [documentsDirectory stringByAppendingPathComponent:@"gameSaves.plist"]; } Sorry, here's the problem: After setting some breakpoints, an error is reached after this line from -saveGame: [NSKeyedArchiver archiveRootObject:savedGames toFile:[self dataFilePath]]; And this is what shows up in the console: 2010-05-11 17:04:08.852 ChessSaver[62065:207] *** -[NSCFType encodeWithCoder:]: unrecognized selector sent to instance 0x3d3cd30 2010-05-11 17:04:08.891 ChessSaver[62065:207] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[NSCFType encodeWithCoder:]: unrecognized selector sent to instance 0x3d3cd30' 2010-05-11 17:04:08.908 ChessSaver[62065:207] Stack: ( 32339035, 31077641, 32720955, 32290422, 32143042, 238843, 25827, 238843, 564412, 342037, 238843, 606848, 17686, 2733061, 4646817, 2733061, 3140430, 3149167, 3144379, 2837983, 2746312, 2773089, 41684313, 32123776, 32119880, 41678357, 41678554, 2777007, 9884, 9738 ) If it matters, -saveGame is called from a UIBarButton in a navigation controller. Any help is appreciated, thanks.
