  • Disable ARC with Xcode 5

    - by user2187565
    First, sorry for my bad english, I'm french and had 15years old but StackOverFlow is for me the best forum for developers. So, in the previous versions of Xcode, we can disable ARC (Automatic Reference Counting) in the project settings when we create the project. Not now with Xcode 5 and ARC to pose me a problem: with an property list file, for the reading step, Xcode send me an error: "implicit conversion of 'int' to 'id' is disallowed with ARC". I had not the problem with the same code with Xcode 4. In my property list file, The keys are numbers and also in my viewController.m . NIKOS M.: No problem, but I don't see how I can add compiler flag with the 5th version of Xcode. The code (with french string...): NSString *error; NSString *rootPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0]; NSString *plistPath = [rootPath stringByAppendingPathComponent:@"Save.plist"]; NSArray *keys = [NSArray arrayWithObjects:@"valeurCompteur1", @"valeurCompteur2", @"valeurCompteur3", @"valeurCompteur4", @"valeurCompteur5", @"nomCompteur1", @"nomCompteur2", @"nomCompteur3", @"nomCompteur4", @"nomCompteur5", nil]; NSArray *objs = [NSArray arrayWithObjects: compteur1, compteur2, compteur3, compteur4, compteur5, nameC1, nameC2, nameC3, nameC4, nameC5, nil]; REVIEW: When I disallow ARC for the target, an warning persist. How I can resolve that please ? Thank you very much.

  • How to (kindly) ask your users to upgrade from IE6?

    - by nickf
    It's no secret at all that IE6 has been a major roadblock to the advancement of the web over the last few years. I couldn't count the number of hours I've spent bashing my head against a wall trying to fix or debug IE6 issues. The way I see it, there are two types of IE6 user. a) the poor corporate schmoe whose IT department doesn't want to upgrade in case something breaks, and b) the mums and dads of the world who think the internet is the blue E on their desktop (and I don't mean that in a nasty way). There's probably a couple of people who know about all the other browsers, but still choose to run IE6. They get what they deserve, IMO. Anyway, getting to the point, I'd say that 90% of my IE6-using visitors are in the the mums and dads category - they're not stupid, they just don't know WHY they should upgrade to IE7 or Firefox or whatever. How do I educate these people without pissing them off? Is there a nice and friendly website I can direct these people to, which explains the reasons for upgrading in plain language? Any mention of "security" or "web standards" I think would just come across as scary. I've just seen http://www.whatbrowser.org which seems to fit the bill nicely. It explains in very basic terms: what a web browser is why you'd want to upgrade it how old your current browser is (subtle hint to those with a 9 year old browser) ..aaaand it's in 22 languages. It's from Google but displays no bias (it links to Firefox, Chrome, Opera, Safari, Internet Explorer displayed in a random order).

  • adding a token onto a webservice or wcf call

    - by duncanUK
    I have an httphandler which I am using to log the http soap request and response for each webservice that is called from my application as a comms log. i would like to inject a token ont he 1st call (possibly the 1st call to invoke the service that is being logged) and then be able to track all subsequent webservice calls run in the same context with this token so i can tie the subsequent calls back up to the original call. so for example. main webservice -> 2nd web service -> another web service [token] [token] [token] -> nth web service [token] I would like to inject the token on the first call to the main webservice (http handler checks if no token, add it), I would like to use the same http handler to intercept each call to the subsequent webservices and pass on the token if it exists already (the job of the httphandler is to log the in/out soap with the token to reference with. I have managed to inject the first token, but my problem is how do I add the token on the subsequent calls.. can I make it stick on the same context or session? My worry is that when we call a new webservice, we create a whole new proxy/http request which will not inhrit the token... or will it?! Ideally I would like it to persist on the http header as I am setting the token as a header at the moment? has anyone got any ideas or a better way of doing this? I would be most greatful for you comments!

  • Fluent NHibernate - How to map the foreign key column as a property

    - by Steve
    I am sure this is a straightforward question but consider the following: I have a reference between company and sector as follows: public class Company { public Guid ID { get; set; } public Sector Sector { get; set; } public Guid SectorID { get; set; } } public class Sector { public Guid ID { get; set; } public string Name { get; set; } } Ok. What I want is the SectorID of the Company object to be populated after I go: (new Company()).Sector = new Sector() { Name="asdf" } and do a flush. The mapping I am using kindly creates an additional column in the database called Sector_Id in the Company table, but this is not available as a property on Company. I want the SectorID property to be filled. The mapping i am currently using in the CompanyMap is References(c = c.Sector).Cascade.All(); Does anyone have any ideas?

  • MVC3 View For Loop values initialization

    - by Ryan
    So I have a for loop in my View that is supposed to render out the input boxes. Now inside these input boxes I want to put lables that disappear when you click on them. This is all simple. Now it's probably because my brain was wired for php first, and it has been difficult to get it to think in lambdas and object orientation, but I can't figure out how to do this: @{ for (int i = 0; i < 3; i++) { <div class="editor-label grid_2">User</div> Model.Users[i].UserFirstName = "First Name"; Model.Users[i].UserLastName = "Last Name"; Model.Users[i].UserEmailAddress = "Email Address"; <div class="grid_10"> @Html.TextBoxFor(m => Model.Users[i].UserFirstName, new { @class = "user-input" }) @Html.TextBoxFor(m => Model.Users[i].UserLastName, new { @class = "user-input" }) @Html.TextBoxFor(m => Model.Users[i].UserEmailAddress, new { @class = "user-input-long" }) @Html.CheckBoxFor(m => Model.Users[i].IsUserAdmin) <span>&nbsp;admin?</span> </div> <div class="clear"> </div> } } And initialize the values for the users. And you're probably thinking "Of course that won't work. You're going to get a Null Reference Exception", and you would be correct. I might need to initialize them somewhere else and I don't realize it but I'm just not sure. I've tried the [DefaultValue("First Name")] route and that doesn't work. I'm probably thinking about this wrong, but my brain is already shot from trying to figure out how to wire up these events to the controller, so any help would be appreciated!

  • NSTableView don't display data

    HI, I have data in NSMutableArray and I want to display it in NSTableView, but only the number of cols has changed. This use of NSTableView is based on tutorial: http://www.youtube.com/watch?v=5teN5pMf-rs FinalImageBrowser is IBOutlet to NSTableView @implementation AppController NSMutableArray *listData; - (void)awakeFromNib { [FinalImageBrowser setDataSource:self]; } - (IBAction)StartReconstruction:(id)sender { NSMutableArray *ArrayOfFinals = [[NSMutableArray alloc] init]; //Array of list with final images NSString *FinalPicture; NSString *PicNum; int FromLine = [TextFieldFrom intValue]; //read number of start line int ToLine = [TextFieldTo intValue]; //read number of finish line int RecLine; for (RecLine = FromLine; RecLine < ToLine; RecLine++) //reconstruct from line to line { Start(RecLine); //start reconstruction //Create path of final image FinalPicture = @"FIN/final"; PicNum = [NSString stringWithFormat: @"%d", RecLine]; FinalPicture = [FinalPicture stringByAppendingString:PicNum]; FinalPicture = [FinalPicture stringByAppendingString:@".bmp"]; [ArrayOfFinals addObject:FinalPicture]; // add path to array } listData = [[NSMutableArray alloc] init]; [listData autorelease]; [listData addObjectsFromArray:ArrayOfFinals]; [FinalImageBrowser reloadData]; NSBeep(); //make some noise NSImage *fin = [[NSImage alloc] initWithContentsOfFile:FinalPicture]; [FinalImage setImage:fin]; } - (int)numberOfRowsInTableView:(NSTableView *)tv { return [listData count]; } - (id)tableView:(NSTableView *)tv objectValueFromTableColumn:(NSTableColumn *)tableColumn row:(int)row { return (NSString *)[listData objectAtIndex:row]; } @end when the StartReconstruction end the number of cols have changed right, but they're empty.

  • Running a Model::find in for loop in cakephp v1.3

    - by Gaurav Sharma
    Hi all, How can I achieve the following result in cakephp: In my application a Topic is related to category, category is related to city and city is finally related to state in other words: topic belongs to category, category belongs to city , city belongs to state.. Now in the Topic controller's index action I want to find out all the topics and it's city and state. How can I do this. I can easily do this using a custom query ($this-Model-query() function ) but then I will be facing pagination difficulties. I tried doing like this function index() { $this->Topic->recursive = 0; $topics = $this->paginate(); for($i=0; $i<count($topics);$i++) { $topics[$i]['City'] = $this->Topic->Category->City->find('all', array('conditions' => array('City.id' => $topics[$i]['Category']['city_id']))); } $this->set(compact('messages')); } The method that I have adopted is not a good one (running query in a loop) Using the recursive property and setting it to highest value (2) will degrade performance and is not going to yield me state information. How shall I solve this ? Please help Thanks

  • Can't diagnose my MySQL root user problem

    - by George Crawford
    Hi all, I have a problem with the MySQL root user in My MySQL setup, and I just can't for the life of me work out how to fix it. It seems that I have somehow messed up the root user, and my access to databases is now very erratic. For reference, I'm using MAMP on OS X to provide the MySQL server. I'm not sure how much that matters though - I'd guess that whatever I've done will require a command-line fix to solve it. I can start MySQL using MAMP as usual, and access databases using the 'standard' users I have created for my PHP apps. However, the root user, which I use in my MySQL GUI client, and also in phpMyAdmin, can only access the "information_schema" database, as well as two I have created manually, and presumably (and mistakenly) left permissions wide open for. My 15 or so other databases cannot be accessed my the root user. When I load up phpMyAdmin, the home screen says: "Create new database: No Privileges". I certainly did at some stage change my root user's password using the MAMP dialog. But I don't remember if I did anything else which might have caused this problem. I've tried changing the password again, and there seems to be no change in the issue. I've also tried resetting root password using the command line, including starting mysql manually with --skip-grant-tables then flushing privs, but again, nothing seems to fix the issue. I've come to the end of my ideas, and would very much appreciate some step-by-step advice and diagnosis from one of the experts here! Many thanks for your help.

  • PDFBox: Problem with converting pdf page into image

    - by user552910
    My mission is pretty simple: converting every single page of a pdf file into images. I tried using icepdf open source version to generate the images but they don't generate the image with the correct font. So I start using PDFBox instead. The code is the following: PDDocument document = PDDocument.load(new File("testing.pdf")); List<PDPage> pages = document.getDocumentCatalog().getAllPages(); for (int i = 0; i < pages.size(); i++) { PDPage singlePage = pages.get(i); BufferedImage buffImage = convertToImage(singlePage, 8, 12); ImageIO.write(buffImage, "png", new File(PdfUtil.DATA_OUTPUT_DIR+(count++)+".png")); } The font looks good, but the pictures within the pdf file look fainted out (See the attachment). I look into the source code but I still have no clue how to fix it. Do you guys have any idea what's going on? Please help. Thanks!!

  • Dynamically cast a control type in runtime

    - by JayT
    Hello, I have an application whereby I dynamically create controls on a form from a database. This works well, but my problem is the following: private Type activeControlType; private void addControl(ContainerControl inputControl, string ControlName, string Namespace, string ControlDisplayText, DataRow drow, string cntrlName) { Assembly assem; Type myType = Type.GetType(ControlName + ", " + Namespace); assem = Assembly.GetAssembly(myType); Type controlType = assem.GetType(ControlName); object obj = Activator.CreateInstance(controlType); Control tb = (Control)obj; tb.Click += new EventHandler(Cntrl_Click); inputControl.Controls.Add(tb); activeControlType = controlType; } private void Cntrl_Click(object sender, EventArgs e) { string test = ((activeControlType)sender).Text; //Problem ??? } How do I dynamically cast the sender object to a class that I can reference the property fields of it. I have googled, and found myself trying everything I have come across..... Now I am extremely confused... and in need of some help Thnx JT

  • Passing NULL value

    - by FFXIII
    Hi. I use an instance of NSXMLParser. I store found chars in NSMutableStrings that are stored in an NSMutableDictionary and these Dicts are then added to an NSMutableArray. When I test this everything seems normal: I count 1 array, x dictionnaries and x strings. In a detailview controller file I want to show my parsed results. I call the class where everthing is stored but I get (null) returned. This is what I do (wrong): XMLParser.h @interface XMLParser : NSObject { NSMutableArray *array; NSMUtableDictionary *dictionary; NSSMutabletring *element; } @property (nonatomic, retain) NSMutableArray *array; @property (nonatomic, retain) NSMutableDictionary *dictionary; @property (nonatomic, retain) NSMutableString *element; XMLParser.m @synthesize array, dictionary, element; //parsing goes on here & works fine //so 'element' is filled with content and stored in a dict in an array //and released at the end of the file In my controller file I do this: controller.h @class XMLParser; @interface controller : UIViewController { XMLParser *aXMLParser; } @property (nonatomic, retain) XMLParser *aXMLParser; controller.m #import "XMLParser.h" @synthesize aXMLParser; - (void)viewDidLoad { NSLog(@"test array: %@", aXMLParser.array); NSLog(@"test dict: %@", aXMLParser.dictionary); NSLog(@"test element: %@", aXMLParser.element); } When I test the value of my array, a dict or an element in the XMLParser.h file I get my result. What am I doing wrong so I can't call my results in my controller file? Any help is welcome, because I'm pretty stuck right now :/

  • Trouble mocking on cucumber + rails

  • Const_cast on a this pointer - would I get told off by other C++ coders for doing this?

    - by BeeBand
    I have a class Game e.g. class Game { public: InitObjects(); ... }; And I have another class Grid, that needs to be initialised with a non-const reference to that Game object. ( A Grid object needs to call functions that can update a Game object ). class Grid { public: Grid(Game & g): game(g){} ... private: Game & game; ... }; The Game object is responsible for initialising the Grid. I did this: void Game::InitObjects() { grid = new Grid(*(const_cast<Game*>(this)) ); } grid is not a member of a Game - it's a global ( argh - i know... I don't mind making it a member, but I have the same problem right? ). Can some seasoned C++ folk tell me if this odd looking const_cast is acceptable?

  • Change Rectangle Fill Based on ColumnWidth of a grid

    - by Coesy
    Essentially i want to do as the title says, if the columnwidth is .50 then the rectangle should be red, if it's .75 then it should be amber, and if it's 1 then it should be green. I thought I could achieve this with DataTriggers but for some reason I am getting "Object Reference Not Set To An Instance Of An Object" error, here is my code, am I missing something here? FYI the width property will be changed in the backend through a timer_tick event. <Grid x:Name="Grid1" Width="300" Height="30"> <Grid.ColumnDefinitions> <ColumnDefinition x:Name="MyColumn1" Width=".50*"></ColumnDefinition> <ColumnDefinition x:Name="MyColumn2" Width=".50*"></ColumnDefinition> </Grid.ColumnDefinitions> <Grid.Triggers> <DataTrigger Binding="{Binding ElementName=MyColumn1,Path=Width}" Value=".50*"> <Setter TargetName="rect" Property="Fill" Value="Red"></Setter> </DataTrigger> <DataTrigger Binding="{Binding ElementName=MyColumn1,Path=Width}" Value=".75*"> <Setter TargetName="rect" Property="Fill" Value="Yellow"></Setter> </DataTrigger> <DataTrigger Binding="{Binding ElementName=MyColumn1,Path=Width}" Value="1"> <Setter TargetName="rect" Property="Fill" Value="Green"></Setter> </DataTrigger> </Grid.Triggers> <Rectangle x:Name="rect" Grid.Column="0" HorizontalAlignment="Stretch"></Rectangle> <Rectangle Grid.Column="1" Fill="Blue"></Rectangle> </Grid>

  • how to switch views according to command

    - by Veer
    I've a main view and many usercontrols. The main view contains a two column grid, with the first column filled with a listbox whose datatemplate consists of a usercontrol and the second column filled with another usercontrol. These two usercontrols have the same datacontext. MainView: <Grid> //Column defs ... <ListView Grid.Column="0" ItemSource="{Binding Foo}"> ... <DataTemplate> <Views: FooView1 /> </DataTemplate> </ListView> <TextBlock Text="{Binding Foo.Count}" /> <StackPanel Grid.Column="1"> <Views: FooView2 /> </StackPanel> <Grid> FooView1: <UserControl> <TextBlock Text="{Binding Foo.Title}"> </UserControl> FooView2: <UserControl> <TextBlock Text="{Binding Foo.Detail1}"> <TextBlock Text="{Binding Foo.Detail2}"> <TextBlock Text="{Binding Foo.Detail3}"> <TextBlock Text="{Binding Foo.Detail4}"> </UserControl> I've no IDE here. Excuse me if there is any syntax error When the user clicks on a button. These two usercontrols have to be replaced by another two usercontrols, so the datacontext changes, the main ui remaining the same. ie, FooView1 by BarView1 and FooView2 by BarView2 In short i want to bind this view changes in mainview to my command (command from Button) How can i do this? Also tell me if i could merge the usercontrol pairs, so that only one view exists for each viewmodel ie, FooView1 and FooView2 into FooView and so on...

  • Maven + SSDM Build and Runtime Environment Automation

    - by Randy
    Preface: My Company, like most, has several run-time environments and several release versions which themselves are composed of different versions of various jars. For example, let us consider release versions 1.1, 1.2, and 1.3 of Software X, which may be deployed to a developer computer, testing, or production. Software-x-1.1 is itself composed of jarA-0.9.1 and jarB-0.7.5, but software-x-1.3 is composed of jarA-1.7.31 and jarB-0.8.1. Currently we use Spring's PropertyPlaceholderConfigurer to configure run-time variables (such as database credentials), however, properties also change with release versions. We also use Maven 2 POM version 4 to specify which versions of our code need to be used. We place the version numbers of our jars as properties within profiles (dev,test,prod) inside of the parent pom and then reference those version numbers in all project poms. As of right now, we have no way to specify which project versions pertain to a given release other than the most current one. Moreover, we deploy our run-time configurations to the SSDM pickup which then configures and creates the services defined by the built versions of our software. -- Questions: Is there any procedure/tool we can use to build our product by merely providing the run-time environment and version number? IE "build 1.1 dev"? Is there anyway we can store the required jar versions for each release build? We are currently versioning all files, including the parent pom, but merely versioning the parent pom does not record which release version is pertinent to that parent pom. What else can we do to further automate the process of builds? For example, if we could manage run-time configurations within the parent pom that would be a step in the right direction, but that seems like a violation of scope. Any tool outside of our framework is inconceivable at this point, but not in the far future. Summary: How can we automate our build process to the fullest extent without being error prone?

  • [C#] Three System.Drawing methods manifest slow drawing or flickery: Solutions? or Other Options?

    - by Luke Mcneice
    Hi all, I am doing a little graphing via the System.Drawing and im having a few problems. I'm holding data in a Queue and i'm drawing(graphing) out that data onto three picture boxes this method fills the picture box then scrolls the graph across. so not to draw on top of the previous drawings (and graduly looking messier) i found 2 solutions to draw the graph. Call plot.Clear(BACKGOUNDCOLOR) before the draw loop [block commented] although this causes a flicker to appear from the time it takes to do the actual drawing loop. call plot.DrawLine(channelPen[5], j, 140, j, 0); just before each drawline [commented] although this causes the drawing to start ok then slow down very quickly to a crawl as if a wait command had been placed before the draw command. Here is the Code for reference: /*plotx.Clear(BACKGOUNDCOLOR) ploty.Clear(BACKGOUNDCOLOR) plotz.Clear(BACKGOUNDCOLOR)*/ for (int j = 1; j < 599; j++) { if (j > RealTimeBuffer.Count - 1) break; QueueEntity past = RealTimeBuffer.ElementAt(j - 1); QueueEntity current = RealTimeBuffer.ElementAt(j); if (j == 1) { //plotx.DrawLine(channelPen[5], 0, 140, 0, 0); //ploty.DrawLine(channelPen[5], 0, 140, 0, 0); //plotz.DrawLine(channelPen[5], 0, 140, 0, 0); } //plotx.DrawLine(channelPen[5], j, 140, j, 0); plotx.DrawLine(channelPen[0], j - 1, (((past.accdata.X - 0x7FFF) / 256) + 64), j, (((current.accdata.X - 0x7FFF) / 256) + 64)); //ploty.DrawLine(channelPen[5], j, 140, j, 0); ploty.DrawLine(channelPen[1], j - 1, (((past.accdata.Y - 0x7FFF) / 256) + 64), j, (((current.accdata.Y - 0x7FFF) / 256) + 64)); //plotz.DrawLine(markerPen, j, 140, j, 0); plotz.DrawLine(channelPen[2], j - 1, (((past.accdata.Z - 0x7FFF) / 256) + 94), j, (((current.accdata.Z - 0x7FFF) / 256) + 94)); } Is there any tricks to avoid these overheads? If not would there be any other/better solutions?

  • Setting synthesized arrays causing memory leaks using nested arrays

    - by webtoad
    Hello: Why is the following code causing a memory leak in an iPhone App? All of the initted objects below leak, including the arrays, the strings and the numbers. So, I'm thinking it has something to do with the the synthesized array property not releasing the object when I set the property again on the second and subsequent time this piece of code is called. Here is the code: "controller" (below) is my custom view controller class, which I have a reference to, and I am setting with this code snippet: sqlite3_stmt *statement; NSMutableArray *foo_IDs = [[NSMutableArray alloc] init]; NSMutableArray *foo_Names = [[NSMutableArray alloc] init]; NSMutableArray *foo_IDsBySection = [[NSMutableArray alloc] init]; NSMutableArray *foo_NamesBySection = [[NSMutableArray alloc] init]; // Get data: NSString *sql = @"select distinct p.foo_ID, p.foo_Name from foo as p "; if (sqlite3_prepare_v2(...) == SQLITE_OK) { while (sqlite3_step(statement) == SQLITE_ROW) { int p_id; NSString *foo_Name; p_id = sqlite3_column_int(statement, 0); char *str2 = (char *)sqlite3_column_text(statement, 1); foo_Name = [NSString stringWithCString:str2]; [foo_IDs addObject:[NSNumber numberWithInt:p_id]]; [foo_Names addObject:foo_Name]; } sqlite3_finalize(statement); } // Pass the array itself into another array: // (normally there is more than one array in each array) [foo_IDsBySection addObject: foo_IDs]; [foo_NamesBySection addObject: foo_Names]; [foo_IDs release]; [foo_Names release]; // Set some synthesized properties (of type NSArray, nonatomic, // retain) in controller: controller.foo_IDsBySection = foo_IDsBySection; controller.foo_NamesBySection = foo_NamesBySection; [foo_IDsBySection release]; [foo_NamesBySection release]; Thanks for any help!

  • Moving from NHibernate to FluentNHibernate: assembly error (related to versions)?

    - by goober
    Not sure where to start, but I had gotten the most recent version of NHibernate, successfully mapped the most simple of business objects, etc. When trying to move to FluentNHibernate and do the same thing, I got this error message on build: "System.IO.FileLoadException: Could not load file or assembly 'NHibernate, Version=2.1.0.4000, Culture=neutral, PublicKeyToken=aa95f207798dfdb4' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference." Background: I'm new to Hibernate, NHibernate, and FluentNHibernate -- but not to .NET, C#, etc. Database I have a database table called Category: (PK) CategoryID (type: int), unique, auto-incrementing UserID (type: uniqueidentifier) -- given the value of the user Guid in ASP.NET database Title (type: varchar(50) -- the title of the category Components involved: I have a SessionProviderClass which creates the mapping to the database I have a Category class which has all the virtual methods for FluentNHibernate to override I have a CategoryMap : ClassMap class, which does the fluent mappings for the entity I have a CategoryRepository class that contains the method to add & save the category I have the TestCatAdd.aspx file which uses the CategoryRepository class. Would be happy to post code for any of those, but I'm not sure that it's necessary, as I think the issue is that somewhere there's a version conflict between what FluentNHibernate references and the NHibernate I have installed from before. Thanks in advance for any help you can give!

  • GWT - problems with constants in css

    - by hba
    Hi, I'm new to GWT; I'm building a small sample app. I have several CSS files. I'm able to successfully use the ClientBundle and CssResource to assign styles to the elements defined in my UiBinder script. Now I'd like to take it one step further and introduce CSS constants using @def css-rule. The @def works great when I define a constant and use it in the same CSS file. However I cannot use it in another CSS file. When I try to use the @eval rule to evaluate an existing constant the compiler throws an execption: "cannot make a static reference to the non-static method ". Here is an example of what I'm trying to do: ConstantStyle.css @def BACKGROUND red; ConstantStyle.java package abc; import ...; interface ConstantStyle extends cssResource { String BACKGROUND(); } MyStyle.css @eval BACKGROUND abc.ConstantStyle.BACKGROUND(); .myClass {background-color: BACKGROUND;} MyStyle.java package abc; import ...; interface ConstantStyle extends cssResource { String myClass; } MyResources.java package abc; import ...; interface MyResources extends ClientBundle { @Source("ConstantStyle.css") ConstantStyle constantStyle(); @Source("MyStyle.css") MyStyle myStyle(); } Thanks in advance!

  • php and mysql site design question

    - by Jacksta
    I am trying to build a website with mysql and php. This is the first site I have attempted so I want to write a little plan and get some feedback. The site allows users to add some text in a text field as a “comment”. Once the comment has been entered into the site it is added to the database where it can be voted for by other users. When a new comment has been added to the database it needs to create a new page, e.g. www.xxxxx.com/commentname or www.xxxxxx.com/?id=99981. There will be a list of "Comments" in the database along with the number of votes for each comment. The home page will have two functions. 1) Allow users to add a "comment" 2) Display two tables, each with 20 rows containing most "popular comments" and "recent comments" Each comment will generate its one page where the comment will be displayed. Here users can read the comment and Vote for the comment if they wish. Please help me out by explaining how to do the following. -Generate a new page whenever a comment is added to the database -Add a vote to the vote count in the comment database. -Display the top 20 most popular comments as per number of votes.

  • Unmanaged DLL (exporting Dialog) + Class Library (DLL) + no Windows Style/Themes

    - by Gohlool
    Hi, I have a managed application TestApplication.exe in C# and Application.EnableVisualStyles() is allready called. I have a Class Library MySharedCode.dll also in C# which uses [DLLImport()] to import some External dialogs out of an unmanaged dll. Well, now I am using (add reference) MySharedCode.dll in my TestApplication.exe and call a function MyTestConfigDlg() out of it. TestClass.MyTestConfigDlg(); OK, everything works fine and I get my dialog, but the dialog has NO XP style/themes? I just wanted to see if it's general problem with managed/unmanged modules, so I used the [DLLImport()] to call the same MyTestConfigDlg() dialog but this time directly in my TestApplication.exe! WOW! Worked as I expected. The Dialog was in XP Style/Themes! so, anybody here who can help me out? FYI: I also tried (just for test) to call MessageBoxA() API call in my Class Library Dll which later called by my TestApplication.exe and the MessageBoxA() had also no Style/Themes! Thanks in advance!

  • How to force inclusion of an object file in a static library when linking into executable?

    - by Brian Bassett
    I have a C++ project that due to its directory structure is set up as a static library A, which is linked into shared library B, which is linked into executable C. (This is a cross-platform project using CMake, so on Windows we get A.lib, B.dll, and C.exe, and on Linux we get libA.a, libB.so, and C.) Library A has an init function (A_init, defined in A/initA.cpp), that is called from library B's init function (B_init, defined in B/initB.cpp), which is called from C's main. Thus, when linking B, A_init (and all symbols defined in initA.cpp) is linked into B (which is our desired behavior). The problem comes in that the A library also defines a function (Af, defined in A/Afort.f) that is intended to by dynamically loaded (i.e. LoadLibrary/GetProcAddress on Windows and dlopen/dlsym on Linux). Since there are no references to Af from library B, symbols from A/Afort.o are not included into B. On Windows, we can artifically create a reference by using the pragma: #pragma comment (linker, "/export:_Af") Since this is a pragma, it only works on Windows (using Visual Studio 2008). To get it working on Linux, we've tried adding the following to A/initA.cpp: extern void Af(void); static void (*Af_fp)(void) = &Af; This does not cause the symbol Af to be included in the final link of B. How can we force the symbol Af to be linked into B?

  • Castle Windsor: Reuse resolved component in OnCreate, UsingFactoryMethod or DynamicParameters

    - by shovavnik
    I'm trying to execute an action on a resolved component before it is returned as a dependency to the application. For example, with this graph: public class Foo : IFoo { } public class Bar { IFoo _foo; IBaz _baz; public Bar(IFoo foo, IBaz baz) { _foo = foo; _baz = baz; } } When I create an instance of IFoo, I want the container to instantiate Bar and pass the already-resolved IFoo to it, along with any other dependencies it requires. So when I call: var foo = container.Resolve<IFoo>(); The container should automatically call: container.Resolve<Bar>(); // should pass foo and instantiate IBaz I've tried using OnCreate, DynamicParameters and UsingFactoryMethod, but the problem they all share is that they don't hold an explicit reference to the component: DynamicParameters is called before IFoo is instantiated. OnCreate is called after, but the delegate doesn't pass the instance. UsingFactoryMethod doesn't help because I need to register these components with TService and TComponent. Ideally, I'd like a registration to look something like this: container.Register<IFoo, Foo>((kernel, foo) => kernel.Resolve<Bar>(new { foo })); Note that IFoo and Bar are registered with the transient life style, which means that the already-resolved instance has to be passed to Bar - it can't be "re-resolved". Is this possible? Am I missing something?
