  • How do I store more information in a marker?

    - by Sebastian
    Hello, I'm using Google Maps v3 and I build in the server side a json collection of location data. So when I receive that, I iterate through that collection and create a marker object for each and every one of them. For each of these markers, I bind them with the click event, so when the user clicks on a marker in the map, it displays an infoWindow with data related to the associated location. I have an array to store all the location got from the server that holds the retrieved json objects and their corresponding marker. The problem is that, even when I have an array that I can reference or iterate through, I need to not only get the marker object when the user clicks on them, but also the location object, that stores more information. I tried to mantain this array of objects and reference it from the calling object without success, because the function is called by the marker and not the location object. So I thought if it's possible to store more information in the google maps marker object like using a general purpose field. Please let me know if more information is needed. Thanks!

  • Boost in Visual Studio 2010, IntelliSense error

    - by Peretz
    Hello, I would like to see if you could orient me. It happens that I compiled and referenced the boost libraries in order to use them with Visual Studio 2010. When building my test project I get these two IntelliSense errors 1 IntelliSense: #error directive: "Macro BOOST_LIB_NAME not set (internal error)" c:\boost_1_43_0\boost\config\auto_link.hpp 2 IntelliSense: #error directive: "some required macros where not defined (internal logic error)." c:\boost_1_43_0\boost\config\auto_link.hpp Checking the auto_link.hpp header file the first error is in this line #ifndef BOOST_LIB_NAME # error "Macro BOOST_LIB_NAME not set (internal error)" #endif Tracing the definition of BOOST_LIB_NAME, it seems that is defined in config.hpp by boost_regex, which code I am including below #if !defined(BOOST_REGEX_NO_LIB) && !defined(BOOST_REGEX_SOURCE) && !defined(BOOST_ALL_NO_LIB) && defined(__cplusplus) # define BOOST_LIB_NAME boost_regex # if defined(BOOST_REGEX_DYN_LINK) || defined(BOOST_ALL_DYN_LINK) # define BOOST_DYN_LINK ... more code and strangely when I point to BOOST_LIB_NAME it defines BOOST_LIB_NAME and the IntelliSense errors disappear. My program builds and executes fine using the Boost:Regex library -- with or without the Intellisense errors; however, I do not understand why these IntelliSense errors appear in the first place, and second why pointing the macro in the config.hpp defines BOOST_LIB_NAME. Any guidance will be greatly appreciated. Thanks, Jaime

  • Find, Find Next?

    - by Tanner
    Hello everyone, I am trying to make a find, find next function for my program, which I did manage to do with this code: int findPos = 0; private void button1_Click(object sender, EventArgs e) { try { string s = textBox1.Text; richTextBox1.Focus(); findPos = richTextBox1.Find(s, findPos, RichTextBoxFinds.None); richTextBox1.Select(findPos, s.Length); findPos += textBox1.Text.Length; //i = richTextBox1.Find(s, i + s.Length, RichTextBoxFinds.None); } catch { MessageBox.Show("No Occurences Found"); findPos = 0; } } And it works great in form1 but if I use this code and try to call it from form2 It doesn't do anything: //Form1 public void FindNext() { try { this.Focus(); Form2 frm2 = new Form2(); string s = frm2.textBox1.Text; richTextBox1.Focus(); findPos = richTextBox1.Find(s, findPos, RichTextBoxFinds.None); richTextBox1.Select(findPos + 1, s.Length); findPos += textBox1.Text.Length; } catch { MessageBox.Show("No Occurences Found"); findPos = 0; } } //Form2 private void button1_Click(object sender, EventArgs e) { Form1 frm1 = new Form1(); frm1.FindNext(); } Does any one know why this is? Thanks,Tanner.

  • what can be causes of http server crash?

    - by mithunmo
    Hello , I am using WAMP server on Windows XP. - Apache 2.2.11 - MySQL 5.1.36 (INNODB engine) - PHP 5.3.0 I observe that my WAMP server crashes in the following scenarios 1) IF I use a Low end PC ( low processor speed and low RAM) 2) After making some changes to httpd.conf file .For eg changing the Allow from IP address . But here it crashes only once and then it starts to work fine. 3) Random crashes CRASH LOG szAppName : httpd.exe szAppVer : 2.2.11.0 szModName : php5ts.dll szModVer : 5.3.0.0 offset : 0000c309 C:\DOCUME~1\blrcom\LOCALS~1\Temp\WERc677.dir00\httpd.exe.mdmp C:\DOCUME~1\blrcom\LOCALS~1\Temp\WERc677.dir00\appcompat.txt My questions 1) Does high CPU utilization/LOW RAM can also cause the HTTP server to crash ? 2) excessive file reading as in every 10 seconds ? 3) unlimited script execution time . I have set the maximum execution time in php script to 0 as my script has to execute for sometimes 2-3 days. Is there any way to avoid this ? 4) Access to Database ? Should we use lock before reading and writing Can these be the reasons for random wamp server crashes ? OR is is some other programming error ? Please guide me . Regards, Mithun

  • HttpServletRequest#login() not working in Java.

    - by Nitesh Panchal
    Hello, j_security_check just doesn't seem enough for me to perform login process. So, instead of submitting the form to j_security_check i created my own servlet and in that i am programmatically trying to do login. This works but i am not able to redirect to my restricted resource. Can anybody tell me what can be the problem? This is processRequest method of my servlet :- protected void processRequest(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { response.setContentType("text/html;charset=UTF-8"); PrintWriter out = response.getWriter(); try { String strUsername = request.getParameter("txtusername"); String strPassword = request.getParameter("txtpassword"); if(strUsername == null || strPassword == null || strUsername.equals("") || strPassword.equals("")) throw new Exception("Username and/or password missing."); request.login(strUsername, strPassword); System.out.println("Login succeeded!!"); if(request.isUserInRole(ROLES.ADMIN.getValue())){//enum System.out.println("Found in Admin Role"); response.sendRedirect("/Admin/home.jsf"); } else if (request.isUserInRole(ROLES.GENERAL.getValue())) response.sendRedirect("/Common/index.jsf"); else //guard throw new Exception("No role for user " + request.getRemoteUser()); }catch(Exception ex){ //patch work why there needs to be blogger here? System.out.println("Invalid username and/or password!!"); response.sendRedirect("/Common/index.jsf"); }finally { out.close(); } } Everything works fine and i can even see message "Found in Admin Role" but problem is even after authenticating i am not able to redirect my request to some other page. Please help geeks.

  • WPF UserControl weird binding problem

    - by Heko
    Hello! Im usign a Ribbon Window and in the "content area beneath" I have a grid in which I will be displaying UserControls. To demonstrate my problem lets take a look at this simple UserControl: <ListView x:Name="lvPersonList"> <ListView.View> <GridView> <GridViewColumn Width="120" Header="Name" DisplayMemberBinding="{Binding Name}"/> <GridViewColumn Width="120" Header="Height" DisplayMemberBinding="{Binding Height}"/> </GridView> </ListView.View> </ListView> And the code: public partial class MyUserControl: UserControl { private List<Person> personList; public TestSnpList() { InitializeComponent(); this.personList = new List<Person>(); this.personList.Add(new Person { Name = "Chuck Norris", Height = 210 }); this.personList.Add(new Person { Name = "John Rambo", Height = 200 }); this.lvPersonList.ItemsSource = personList; } } public class Person { public string Name { get; set; } public int Height { get; set; } } The parent Window: <Grid x:Name="grdContent" DockPanel.Dock="Top"> <controls:MyUserControl x:Name="myUserControl" Visibility="Visible"/> </Grid> I don't understant why this binding doesn't work. Instead of values (Name and Height) I get full class names. If I use this code in a Window it works fine. Any ideas? I would like this user contorl works for itself (it gets the data form the DB and represents it in a ListView)... Thanks!

  • Multidimensional array with unequal second dimension size using malloc()

    - by user288422
    Hello, I am playing around with multidimensional array of unequal second dimension size. Lets assume that I need the following data structure: [&ptr0]-[0][1][2][3][4][5][6][7][8][9] [&ptr1]-[0][1][2] [&ptr2]-[0][1][2][3][4] int main() { int *a[3]; int *b; int i; a[0] = (int *)malloc(10 * sizeof(int)); a[1] = (int *)malloc(2 * sizeof(int)); a[2] = (int *)malloc(4 * sizeof(int)); for(i=0; i<10; i++) a[0][i]=i; for(i=0; i<2; i++) a[1][i]=i; for(i=0; i<4; i++) a[2][i]=i; } I did some tests and it seems like I can store a value at a[1][3]. Does it mean that rows in my array are of equal size 10?

  • RapidXML, reading and saving values

    - by Layne
    Hello, I've worked myself through the rapidXML sources and managed to read some values. Now I want to change them and save them to my XML file: Parsing file and set a pointer void SettingsHandler::getConfigFile() { pcSourceConfig = parsing->readFileInChar(CONF); cfg.parse<0>(pcSourceConfig); } Reading values from XML void SettingsHandler::getDefinitions() { SettingsHandler::getConfigFile(); stGeneral = cfg.first_node("settings")->value(); /* stGeneral = 60 */ } Changing values and saving to file void SettingsHandler::setDefinitions() { SettingsHandler::getConfigFile(); stGeneral = "10"; cfg.first_node("settings")->value(stGeneral.c_str()); std::stringstream sStream; sStream << *cfg.first_node(); std::ofstream ofFileToWrite; ofFileToWrite.open(CONF, std::ios::trunc); ofFileToWrite << "<?xml version=\"1.0\"?>\n" << sStream.str() << '\0'; ofFileToWrite.close(); } Reading file into buffer char* Parser::readFileInChar(const char* p_pccFile) { char* cpBuffer; size_t sSize; std::ifstream ifFileToRead; ifFileToRead.open(p_pccFile, std::ios::binary); sSize = Parser::getFileLength(&ifFileToRead); cpBuffer = new char[sSize]; ifFileToRead.read( cpBuffer, sSize); ifFileToRead.close(); return cpBuffer; } However, it's not possible to save the new value. My code is just saving the original file with a value of "60" where it should be "10". Rgds Layne

  • Help needed implementing a web based file management system with a file hierarchy system, help neede

    - by molleman
    Hello i am trying to create a web application that will allow users to upload files online, i am using gwt while using hibernate for database communication, i am able to upload file to a server , and store them on the server. but what i want is to associate the files with a user. i want the user to be able to create folders and store a file in sub folders. my logic was to use the composite pattern to store folders and fileLocations with a user but i am am finding it difficult to implement this so i can show the files and folders within a gwt tree. what would be the best way to implement a hierarchy of folders and information of the location of a file so it could be displayed in a gwt tree? what i did have was a User would hold a reference to a root folder and then each sub folder could hold folders or fileLocations. i used the composite pattern to implement the file hierarchy, but when i want to display a the contents of a folder i need a for loop for each list. so i could a folder within a folder within a folder that would need 3 for loops to show the contents of my folders. What is the best way to implement this file management system. so what do you guys think?

  • Django queryset not returning the same values as the generated sql

    - by HRCerqueira
    Hello guys, I have the following queryset: subscribers = User.objects.values('email', 'username').filter( Q(subscription_settings__new_question='i') | Q(subscription_settings__new_question_watched_tags='i', marked_tags__id__in=question.tags.values('id'), tag_selections__reason='good') ).exclude(id=question.author.id) The problem is that when I evaluate the query I get only the values that are filtered by the first Q object (even if I reverse the order of the objects). So lets say that I was expecting the user A, B, C and D, where A and B are filtered by the first Q object and C and D by the second. But the queryset only returns A and B. I used the django debug toolbar to see the query that was actually being executed (and then I used a direct print statement like "print subscriber.query.as_sql()" just to be sure) and then evaluated the query directly using psql (I'm using postgres by the way), and I get the results I expect. Here's the query btw: SELECT "auth_user"."email", "auth_user"."username" FROM "auth_user" LEFT OUTER JOIN "forum_markedtag" ON ("auth_user"."id" = "forum_markedtag"."user_id") INNER JOIN "forum_defaultsubscriptionsetting" ON ("auth_user"."id" = "forum_defaultsubscriptionsetting"."user_id") WHERE ((("forum_markedtag"."reason" = E'good' AND "forum_defaultsubscriptionsetting"."new_question_watched_tags" = E'i' AND "forum_markedtag"."tag_id" IN (SELECT U0."id" FROM "tag" U0 INNER JOIN "question_tags" U1 ON (U0."id" = U1."tag_id") WHERE U1."question_id" = 64 )) OR "forum_defaultsubscriptionsetting"."new_question" = E'i' ) AND NOT ("auth_user"."id" = 10 )) Thanks in advance EDIT: I tried to break the queryset into two, one that uses the first Q object as the filter and another one with the second Q object, and although the second queryset produces the correct sql that returns the correct values when evaluated directly, it still doesn't return nothing when evaluated as a django queryset. heres the alternative code: subscribers = User.objects.values('email', 'username').filter( subscription_settings__new_question='i').exclude(id=question.author.id) subscribers2 = User.objects.values('email', 'username').filter( subscription_settings__new_question_watched_tags='i', marked_tags__id__in=question.tags.values('id'), tag_selections__reason='good').exclude(id=question.author.id)

  • Map/Reduce on an array of hashes in CouchDB

    - by sebastiangeiger
    Hello everyone, I am looking for a map/reduce function to calculate the status in a Design Document. Below you can see an example document from my current database. { "_id": "0238f1414f2f95a47266ca43709a6591", "_rev": "22-24a741981b4de71f33cc70c7e5744442", "status": "retrieved image urls", "term": "Lucas Winter", "urls": [ { "status": "retrieved", "url": "http://...." }, { "status": "retrieved", "url": "http://..." } ], "search_depth": 1, "possible_labels": { "gender": "male" }, "couchrest-type": "SearchTerm" } I'd like to get rid of the status key and rather calculate it from the statuses of the urls. My current by_status view looks like the following: function(doc) { if (doc['status']) { emit(doc['status'], null); } } I tried some things but nothing actually works. Right now my Map Function looks like this: function(doc) { if(doc.urls){ emit(doc._id, doc.urls) } } And my Reduce Function function(key, value, rereduce){ var reduced_status = "retrieved" for(var url in value){ if(url.status=="new"){ reduced_status = "new"; } } return reduced_status; } The result is that I get retrieved everywhere which is definitely not right. I tried to narrow down the problem and it seems to be that value is no array, when I use the following Reduce Function I get length 1 everywhere, which is impossible because I have 12 documents in my database, each containing between 20 to 200 urls function(key, value, rereduce){ return value.length; } What am I doing wrong? (I know I want you to write code for me and I'm feeling guilty, but right now I do the calculation of the statuses in ruby after getting the data from the database. It would be nice to already get the right data from the database)

  • Get paperclip to crop the image without validating

    - by Micke
    Hello fellow stackoverflow members. I have been following this guide to enable users to have their own avatar. But i have bumped in to a litle problem. When the user is cropping the image the model tries to validate all my validations. My user model looks like this: class User < ActiveRecord::Base has_attached_file :avatar, :styles => { :small => "100x100>", :large => "500x500>" }, :processors => [:cropper] attr_accessor :password, :crop_x, :crop_y, :crop_w, :crop_h attr_accessible :crop_x, :crop_y, :crop_w, :crop_h validates_confirmation_of :password validates_presence_of :password And when the user runs the crop updating script the user model tries to validate the password. But because i have no password field on the cropping page it can't validate it. Here is the updating of the crop: @user = User.find(current_user.id) if @user.update_attributes(params[:user]) flash[:notice] = "Successfully updated user." end How can i bypass this in a easy and clean way?

  • Android -- How to position View off-screen?

    - by borg17of20
    Hello all, I'm trying to animate a simple ImageView in my application and I want it to slide in from the bottom of the screen and come to a resting position where the top 50px of the view is off the top of the screen (e.g. the final position of the ImageView should be -50px in X). I've tried to use the AbsoluteLayout to do this, but this actually cuts off the top 50px of the ImageView such that the top 50px is never rendered. I need to have the top 50px of the ImageView visible/rendered while it's animating and then simply have it come to a rest slightly off-screen. I hope I've explained that well enough. Here is what I'm currently using as a layout and the slide-in animation (this currently doesn't render the top 50px of the ImageView): Layout: <?xml version="1.0" encoding="utf-8"?> <AbsoluteLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_height="fill_parent" android:layout_width="fill_parent" android:id="@+id/QuickPlayClipLayout"> <ImageView android:id="@+id/Clip" android:background="@drawable/clip" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_y="-50dp"> </ImageView> </AbsoluteLayout> Animation: <?xml version="1.0" encoding="utf-8"?> <set xmlns:android="http://schemas.android.com/apk/res/android"> <translate android:fromYDelta="100%p" android:toYDelta="0" android:duration="1000"/> <alpha android:fromAlpha="0.0" android:toAlpha="1.0" android:duration="1000" /> </set> Thanks in advance.

  • array retain question

    - by Cosizzle
    Hello, im fairly new to objective-c, most of it is clear however when it comes to memory managment I fall a little short. Currently what my application does is during a NSURLConnection when the method -(void)connectionDidFinishLoading:(NSURLConnection *)connection is called upon I enter a method to parse some data, put it into an array, and return that array. However I'm not sure if this is the best way to do so since I don't release the array from memory within the custom method (method1, see the attached code) Below is a small script to better show what im doing .h file #import <UIKit/UIKit.h> @interface memoryRetainTestViewController : UIViewController { NSArray *mainArray; } @property (nonatomic, retain) NSArray *mainArray; @end .m file #import "memoryRetainTestViewController.h" @implementation memoryRetainTestViewController @synthesize mainArray; // this would be the parsing method -(NSArray*)method1 { // ???: by not release this, is that bad. Or does it get released with mainArray NSArray *newArray = [[NSArray alloc] init]; newArray = [NSArray arrayWithObjects:@"apple",@"orange", @"grapes", "peach", nil]; return newArray; } // this method is actually // -(void)connectionDidFinishLoading:(NSURLConnection *)connection -(void)method2 { mainArray = [self method1]; } // Implement viewDidLoad to do additional setup after loading the view, typically from a nib. - (void)viewDidLoad { [super viewDidLoad]; } - (void)didReceiveMemoryWarning { // Releases the view if it doesn't have a superview. [super didReceiveMemoryWarning]; // Release any cached data, images, etc that aren't in use. } - (void)viewDidUnload { mainArray = nil; // Release any retained subviews of the main view. // e.g. self.myOutlet = nil; } - (void)dealloc { [mainArray release]; [super dealloc]; } @end

  • UIImageView size becomes equal to the size of image it holds after autoresizing

    - by abura
    Hello, I faced a strange problem. My task is to provide scaling an image to fill the UIImageView frame. The UIImageView is a subview of another view. The code is following: CGRect frame=CGRectMake(0,0,viewSize.width,viewSize.height); UIView* backView=[[UIView alloc] initWithFrame:frame]; backView.autoresizesSubviews=YES; backView.autoresizingMask=UIViewAutoresizingFlexibleWidth; UIImageView* imgView=[[UIImageView alloc]initWithFrame:viewFrame]; imgView.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight; imgView.contentMode=UIViewContentModeScaleToFill; [subcellBackView addSubview:imgView]; [imgView release]; When the image arrives, it is assigned the the imgView: imgView.image=img; The image is scaled according to the imgView's size. Everything is all right until the iPhone (simulator) rotation. After first autoresizing the imgView size becomes equal to the image size (which is much greater) and overlaps its superview frame. The superview frame reacts properly to the orientation change. Could you please help?

  • establishing a socket connection from iPhone to MAC/PC

    Hello, I just started getting into XCode and Co. What I am trying is to send accelerometer data via WLAN to a PC or MAC over a Socket connection. I am trying at the moment with the iPhone simulator, on the other site a netbook with a JAVA program shall receive a test string for starters. Unfortunately my socket will not initialize.

  • Beanshell in Ant yielding, "Unable to create javax script engine for beanshell"

In UITableView - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { NSInteger row=[indexPath row]; NSInteger section=[indexPath section]; //UITableViewCell *cell=[tableView dequeueReusableCellWithIdentifier:@"any-cell"]; static NSString *SimpleTableIdentifier1 = @"SimpleTableIdentifier1"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier: SimpleTableIdentifier1]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier: SimpleTableIdentifier1] autorelease]; } UIProgressView *aUIProgressView; aUIProgressView =[[UIProgressView alloc] initWithFrame:CGRectMake( 10.9f,48.0f,300.0f,28.0f)]; [aUIProgressView setTag:row]; [aUIProgressView setProgress:0]; [cell addSubview:aUIProgressView]; [self startADownloadThread : [[downloadArray objectAtIndex:row] getURL] progressview:switchView ]; [aUIProgressView release]; [cell setText: [[downloadArray objectAtIndex:row] getURL]]; return cell; } It calls 'startADownloadThread' - (IBAction)startADownloadThread:(NSString *)fileurl progressview:(UIProgressView *)a { [a setProgress:0]; NSLog(@"Value: %f", [a progress]); [networkQueue cancelAllOperations]; [networkQueue setDownloadProgressDelegate:a]; [networkQueue setDelegate:self]; [networkQueue setRequestDidFinishSelector:@selector(requestDone:)]; [networkQueue setShowAccurateProgress:true]; NSURL *url = [NSURL URLWithString:fileurl]; ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:url]; [request setDelegate:self]; [networkQueue addOperation:request]; [networkQueue go]; } I hope each aUIProgressView display the download progress of each download thread. The above source codes : Display the aUIProgressView list correctly, but only the last aUIProgressView link to a thread display the correct progress, others' value are 0 Welcome any comment Thanks interdev

  • function to get the file name of an URL

    - by user262325
    Hello everyone I have some source code to get the file name of an url for example: http://www.google.com/a.pdf I hope to get a.pdf because the way to join 2 NSStrings I can get is 'appendString' which only for adding a string at right side, so I planned to check each char one by one from the right side of string 'http://www.google.com/a.pdf', when it reach at the char '/', stop the checking, return string fdp.a , after that I change fdp.a to a.pdf source codes are below -(NSMutableString *) getSubStringAfterH : originalString:(NSString *)s0 { NSInteger i,l; l=[s0 length]; NSMutableString *h=[[NSMutableString alloc] init]; NSMutableString *ttt=[[NSMutableString alloc] init ]; for(i=l-1;i>=0;i--) //check each char one by one from the right side of string 'http://www.google.com/a.pdf', when it reach at the char '/', stop { ttt=[s0 substringWithRange:NSMakeRange(i, 1)]; if([ttt isEqualToString:@"/"]) { break; } else { [h appendString:ttt]; } } [ttt release]; //below are to change the sequence of char in h // txt.edcba -> abcde.txt NSMutableString *h1=[[[NSMutableString alloc] initWithFormat:@""] autorelease]; for (i=[h length]-1;i>=0;i--) { NSMutableString *t1=[[NSMutableString alloc] init ]; t1=[h substringWithRange:NSMakeRange(i, 1)]; [h1 appendString:t1]; [t1 release]; } [h release]; return h1; } h1 can reuturn the coorect string a.pdf, but if it returns to the codes where it was called, after a while system reports 'double free * set a breakpoint in malloc_error_break to debug' I checked a long time and foudn that if I removed the code ttt=[s0 substringWithRange:NSMakeRange(i, 1)]; everything will be Ok (of course getSubStringAfterH can not returns the corrent result I expected.), no error reported. I try to fix the bug a few hours, but still no clue. Welcome any comment Thanks interdev

  • Algorithm to get through a maze

    - by Sam
    Hello, We are currently programming a game (its a pretty unknown language: modula 2), And the problem we encountered is the following: we have a maze (not a perfect maze) in a 17 x 12 grid. The computer has to generate a way from the starting point (9, 12) to the end point (9, 1). I found some algorithms but they dont work when the robot has to go back: xxxxx x => x x xxx or: xxxxx x xxxxxx x x x x x xxxxxx x => x xxxxxxxxx I found a solution for the first example type but then the second type couldn't be solved and the solution I made up for the second type would cause the robot to get stuck in the first type of situation. It's a lot of code so i'll give the idea: WHILE (end destination not reached) DO { try to go right, if nothing blocks you: go right if you encounter a block, try up until you can go right, if you cant go up anymore try going down until you can go right, (starting from the place you first were blocked), if you cant go down anymore, try one step left and fill the spaces you tested with blocks. } This works for the first type of problem ... not for the second one. Now it could be that i started wrong so i am open for better algorithms or solutions specificaly to how i could improve my algorithm. Thanks a lot!!

  • Error in WCF service - Silverlight client communication.

    - by David
    I created a WCF service and I planned to consume this in a Silverlight application. So I created the WCF service in the Website host project. The service is a simple WCF service that only returns a number - something like a Hello World WCF-SL. So after adding a service reference in the silverlight client project to the Service URI, after calling async the service method (by using the generated proxy), I get the following exception in the callback method: An error occurred while trying to make a request to URI 'http://localhost:4566/SLService.svc'. This could be due to attempting to access a service in a cross-domain way without a proper cross-domain policy in place, or a policy that is unsuitable for SOAP services. You may need to contact the owner of the service to publish a cross-domain policy file and to ensure it allows SOAP-related HTTP headers to be sent. This error may also be caused by using internal types in the web service proxy without using the InternalsVisibleToAttribute attribute. Please see the inner exception for more details. I only created a HelloWorld WCF service with nothing else but a simple method that returns a dumb number and it's hosted on my locally. Must I have clientaccesspolicy.xml or crossdomain.xml? I acces my service locally. Every time I create a new simple/dumb WCF-SL solution, I get this error. I use VS2010 and Silverlight 4. I cannot get a simple/dumb WCF-SL solution working locally. Is there something wrong with the configuration? On another machine in the same network, it does work properly, so I assume something is misconfigured. Any thoughts?

  • jQuery / jEditable and jQuery UI Dialog. Re-populating table cell.

    - by solefald
    Hello, this is my first time using JS, so i really have no idea what i am doing. I have a table with data, and using jEditable to allow a user to edit the data and POST it to my php script. When user hits "Save", it opens jQuery UI with the data from php script and it seems to work fine, however, if the user hits Cancel or Esc to close the jQuery UI dialog, they and up back on the page, but the cell they tried to edit is now completely empty. How do i get the cell re-populated? Thank you! $(".editable_textarea").editable("/path/to/my/scrip.php", { indicator : "<img src='/images/indicator.gif'>", type : 'textarea', submitdata: { _method: "post", uri: "<?php echo $this->uri->segment(3); ?>" }, select : false, submit : 'Save', cancel : 'Cancel', tooltip : "Click to edit...", cssclass : "editable", onblur: "cancel", cssclass: "edit_destination", callback: function(value, settings) { $(this).dialog({ autoOpen: true, width: 400, modal: true, position: "center", resizable: false, draggable: false, title: "Pending Changes", buttons: { "Cancel": function() { $(this).dialog("close"); }, "Confirm Changes": function() { document.findSameDestination.submit(); } } }); $('form#findSameDestination').submit(function(){ $(this).dialog('open'); return false; }); $(this).editable("disable"); }, data: function(value, settings) { var retval = value.replace(/<br[\s\/]?>/gi, '\n'); retval = retval.replace(/(<([^>]+)>)/gi, ''); return retval; } });
