  • Problem communicating with one machine in my domain

    - by pmaroun
    Context: 3 HyperV guest images (DC, SQL, MOSS) 1 internal network 1 domain (PJM.COM) DC: 192.168.0.192 SQL: 192.168.0.153 MOSS:192.168.0.160 I am having communication problems from/to the MOSS machine from the other two. I removed the MOSS machine from the domain and cannot rejoin. When I ping the MOSS machine from DC, I get the following response: Pinging MOSS [192.168.0.152] Reply from 192.168.0.192 Destination host unreachable (4 times) When I ping the MOSS machine from SQL, I get the following response: Pinging MOSS [192.168.0.152] Reply from 192.168.0.153 Destination host unreachable (4 times) From the MOSS machine, I can ping the server names, however I cannot ping the FQDN. When I ping from the DC and SQL machines, I get IPv4 addresses. When I ping from the MOSS machine, I get IPv6 addresses. I'm a developer and don't know what steps to take to resolve this issue. Please help!?

  • Stairway to Database Design STEP 2: Domains, Constraints and Defaults

    A clear understanding of SQL Data Types and domains is a fundamental requirement for the Database Developer, but it is not elementary. If you select the most appropriate data type, it can sidestep a variety of errors. Furthermore, if you then define the data domains as exactly as possible via constraints, you can catch a variety of those problems that would otherwise bedevil the work of the application programmer.

  • How should I refactor switch statements like this (Switching on type) to be more OO?

    - by Taytay
    I'm seeing some code like this in our code base, and want to refactor it: (Typescript psuedocode follows): class EntityManager{ private findEntityForServerObject(entityType:string, serverObject:any):IEntity { var existingEntity:IEntity = null; switch(entityType) { case Types.UserSetting: existingEntity = this.getUserSettingByUserIdAndSettingName(serverObject.user_id, serverObject.setting_name); break; case Types.Bar: existingEntity = this.getBarByUserIdAndId(serverObject.user_id, serverObject.id); break; //Lots more case statements here... } return existingEntity; } } The downsides of switching on type are self-explanatory. Normally, when switching behavior based on type, I try to push the behavior into subclasses so that I can reduce this to a single method call, and let polymorphism take care of the rest. However, the following two things are giving me pause: 1) I don't want to couple the serverObject with the class that is storing all of these objects. It doesn't know where to look for entities of a certain type. And unfortunately, the identity of a type of ServerObject varies with the type of ServerObject. (So sometimes it's just an ID, other times it's a combination of an id and a uniquely identifying string, etc). And this behavior doesn't belong down there on those subclasses. It is the responsibility of the EntityManager and its delegates. 2) In this case, I can't modify the ServerObject classes since they're plain old data objects. It should be mentioned that I've got other instances of the above method that take a parameter like "IEntity" and proceed to do almost the same thing (but slightly modify the name of the methods they're calling to get the identity of the entity). So, we might have: case Types.Bar: existingEntity = this.getBarByUserIdAndId(entity.getUserId(), entity.getId()); break; So in that case, I can change the entity interface and subclasses, but this isn't behavior that belongs in that class. So, I think that points me to some sort of map. So eventually I will call: private findEntityForServerObject(entityType:string, serverObject:any):IEntity { return aMapOfSomeSort[entityType].findByServerObject(serverObject); } private findEntityForEntity(someEntity:IEntity):IEntity { return aMapOfSomeSort[someEntity.entityType].findByEntity(someEntity); } Which means I need to register some sort of strategy classes/functions at runtime with this map. And again, I darn well better remember to register one for each my my types, or I'll get a runtime exception. Is there a better way to refactor this? I feel like I'm missing something really obvious here.

  • Entity Framework many-to-many using VB.Net Lambda

    - by bgs264
    Hello, I'm a newbie to StackOverflow so please be kind ;) I'm using Entity Framework in Visual Studio 2010 Beta 2 (.NET framework 4.0 Beta 2). I have created an entity framework .edmx model from my database and I have a handful of many-to-many relationships. A trivial example of my database schema is Roles (ID, Name, Active) Members (ID, DateOfBirth, DateCreated) RoleMembership(RoleID, MemberID) I am now writing the custom role provider (Inheriting System.Configuration.Provider.RoleProvider) and have come to write the implementation of IsUserInRole(username, roleName). The LINQ-to-Entity queries which I wrote, when SQL-Profiled, all produced CROSS JOIN statements when what I want is for them to INNER JOIN. Dim query = From m In dc.Members From r In dc.Roles Where m.ID = 100 And r.Name = "Member" Select m My problem is almost exactly described here: http://stackoverflow.com/questions/553918/entity-framework-and-many-to-many-queries-unusable I'm sure that the solution presented there works well, but whilst I studied Java at uni and I can mostly understand C# I cannot understand this Lambda syntax provided and I need to get a similar example in VB. I've looked around the web for the best part of half a day but I'm not closer to my answer. So please can somebody advise how, in VB, I can construct a LINQ statement which would do this equivalent in SQL: SELECT rm.RoleID FROM RoleMembership rm INNER JOIN Roles r ON r.ID = rm.RoleID INNER JOIN Members m ON m.ID = rm.MemberID WHERE r.Name = 'Member' AND m.ID = 101 I would use this query to see if Member 101 is in Role 3. (I appreciate I probably don't need the join to the Members table in SQL but I imagine in LINQ I'd need to bring in the Member object?) UPDATE: I'm a bit closer by using multiple methods: Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load Dim count As Integer Using dc As New CBLModel.CBLEntities Dim persons = dc.Members.Where(AddressOf myTest) count = persons.Count End Using System.Diagnostics.Debugger.Break() End Sub Function myTest(ByVal m As Member) As Boolean Return m.ID = "100" AndAlso m.Roles.Select(AddressOf myRoleTest).Count > 0 End Function Function myRoleTest(ByVal r As Role) As Boolean Return r.Name = "Member" End Function SQL Profiler shows this: SQL:BatchStarting SELECT [Extent1].[ID] AS [ID], ... (all columns from Members snipped for brevity) ... FROM [dbo].[Members] AS [Extent1] RPC:Completed exec sp_executesql N'SELECT [Extent2].[ID] AS [ID], [Extent2].[Name] AS [Name], [Extent2].[Active] AS [Active] FROM [dbo].[RoleMembership] AS [Extent1] INNER JOIN [dbo].[Roles] AS [Extent2] ON [Extent1].[RoleID] = [Extent2].[ID] WHERE [Extent1].[MemberID] = @EntityKeyValue1',N'@EntityKeyValue1 int',@EntityKeyValue1=100 SQL:BatchCompleted SELECT [Extent1].[ID] AS [ID], ... (all columns from Members snipped for brevity) ... FROM [dbo].[Members] AS [Extent1] I'm not certain why it is using sp_execsql for the inner join statement and why it's still running a select to select ALL members though. Thanks. UPDATE 2 I've written it by turning the above "multiple methods" into lambda expressions then all into one query, like this: Dim allIDs As String = String.Empty Using dc As New CBLModel.CBLEntities For Each retM In dc.Members.Where(Function(m As Member) m.ID = 100 AndAlso m.Roles.Select(Function(r As Role) r.Name = "Doctor").Count > 0) allIDs &= retM.ID.ToString & ";" Next End Using But it doesn't seem to work: "Doctor" is not a role that exists, I just put it in there for testing purposes, yet "allIDs" still gets set to "100;" The SQL in SQL Profiler this time looks like this: SELECT [Project1].* FROM ( SELECT [Extent1].*, (SELECT COUNT(1) AS [A1] FROM [dbo].[RoleMembership] AS [Extent2] WHERE [Extent1].[ID] = [Extent2].[MemberID]) AS [C1] FROM [dbo].[Members] AS [Extent1] ) AS [Project1] WHERE (100 = [Project1].[ID]) AND ([Project1].[C1] > 0) For brevity I turned the list of all the columns from the Members table into * As you can see it's just ignoring the "Role" query... :/

  • PHP script causes segmentation fault then the browser asks me to download the .php file with nothing in it?

    - by John
    I've noticed an unusual problem with some of my php programs. Sometimes when visiting a page like profile.edit.php, the browser throws a dialogue box asking to download profile.edit.php page. When I download it, there's nothing in the file. profile.edit.php is supposed to be a web form that edits user information. I've noticed this on some of my other php pages as well. I look in my apache error logs, and I see a segmentation fault message: [Mon Mar 08 15:40:10 2010] [notice] child pid 480 exit signal Segmentation fault (11) And also, the issue may or may not appear depending on which server I deploy my application too. Additonal Details This doesn't happen all the time though. It only happens sometimes. For example, profile.edit.php will load properly. But as soon as I hit the save button (form action="profile.edit.php?save=true"), then the page asks me to download profile.edit.php. Could it be that sometimes my php scripts consume too much resources? Sample code Upon save action, my profile.edit.php includes a data_access_object.php file. I traced the code in data_access_object.php to this line here if($params[$this->primaryKey]) { $q = "UPDATE $this->tableName SET ".implode(', ', $fields)." WHERE ".$this->primaryKey." = ?$this->primaryKey"; $this->bind($this->primaryKey, $params[$this->primaryKey], $this->tblFields[$this->primaryKey]['mysqlitype']); } else { $q = "INSERT $this->tableName SET ".implode(', ', $fields); } // Code executes perfectly up to this point // echo 'print this'; exit; // if i uncomment this line, profile.edit.php will actually show 'print this'. If I leave it commented, the browser will ask me to download profile.edit.php if(!$this->execute($q)){ $this->errorSave = -3; return false;} // When I jumped into the function execute(), every line executed as expected, right up to the return statement. And if it helps, here's the function execute($sql) in data_access_object.php function execute($sql) { // find all list types and explode them // eg. turn ?listId into ?listId0,?listId1,?listId2 $arrListParam = array_bubble_up('arrayName', $this->arrBind); foreach($arrListParam as $listName) if($listName) { $explodeParam = array(); $arrList = $this->arrBind[$listName]['value']; foreach($arrList as $key=>$val) { $newParamName = $listName.$key; $this->bind($newParamName,$val,$this->arrBind[$listName]['type']); $explodeParam[] = '?'.$newParamName; } $sql = str_replace("?$listName", implode(',',$explodeParam), $sql); } // replace all ?varName with ? for syntax compliance $sqlParsed = preg_replace('/\?[\w\d_\.]+/', '?', $sql); $this->stmt->prepare($sqlParsed); // grab all the parameters from the sql to create bind conditions preg_match_all('/\?[\w\d_\.]+/', $sql, $matches); $matches = $matches[0]; // store bind conditions $types = ''; $params = array(); foreach($matches as $paramName) { $types .= $this->arrBind[str_replace('?', '', $paramName)]['type']; $params[] = $this->arrBind[str_replace('?', '', $paramName)]['value']; } $input = array('types'=>$types) + $params; // bind it if(!empty($types)) call_user_func_array(array($this->stmt, 'bind_param'), $input); $stat = $this->stmt->execute(); if($GLOBALS['DEBUG_SQL']) echo '<p style="font-weight:bold;">SQL error after execution:</p> ' . $this->stmt->error.'<p>&nbsp;</p>'; $this->arrBind = array(); return $stat; }

  • C/PHP: How do I convert the following PHP JSON API script into a C plugin for apache?

    - by TeddyB
    I have a JSON API that I need to provide super fast access to my data through. The JSON API makes a simply query against the database based on the GET parameters provided. I've already optimized my database, so please don't recommend that as an answer. I'm using PHP-APC, which helps PHP by saving the bytecode, BUT - for a JSON API that is being called literally dozens of times per second (as indicated by my logs), I need to reduce the massive RAM consumption PHP is consuming ... as well as rewrite my JSON API in a language that execute much faster than PHP. My code is below. As you can see, is fairly straight forward. <?php define(ALLOWED_HTTP_REFERER, 'example.com'); if ( stristr($_SERVER['HTTP_REFERER'], ALLOWED_HTTP_REFERER) ) { try { $conn_str = DB . ':host=' . DB_HOST . ';dbname=' . DB_NAME; $dbh = new PDO($conn_str, DB_USERNAME, DB_PASSWORD); $params = array(); $sql = 'SELECT homes.home_id, address, city, state, zip FROM homes WHERE homes.display_status = true AND homes.geolat BETWEEN :geolatLowBound AND :geolatHighBound AND homes.geolng BETWEEN :geolngLowBound AND :geolngHighBound'; $params[':geolatLowBound'] = $_GET['geolatLowBound']; $params[':geolatHighBound'] = $_GET['geolatHighBound']; $params[':geolngLowBound'] =$_GET['geolngLowBound']; $params[':geolngHighBound'] = $_GET['geolngHighBound']; if ( isset($_GET['min_price']) && isset($_GET['max_price']) ) { $sql = $sql . ' AND homes.price BETWEEN :min_price AND :max_price '; $params[':min_price'] = $_GET['min_price']; $params[':max_price'] = $_GET['max_price']; } if ( isset($_GET['min_beds']) && isset($_GET['max_beds']) ) { $sql = $sql . ' AND homes.num_of_beds BETWEEN :min_beds AND :max_beds '; $params['min_beds'] = $_GET['min_beds']; $params['max_beds'] = $_GET['max_beds']; } if ( isset($_GET['min_sqft']) && isset($_GET['max_sqft']) ) { $sql = $sql . ' AND homes.sqft BETWEEN :min_sqft AND :max_sqft '; $params['min_sqft'] = $_GET['min_sqft']; $params['max_sqft'] = $_GET['max_sqft']; } $stmt = $dbh->prepare($sql); $stmt->execute($params); $result_set = $stmt->fetchAll(PDO::FETCH_ASSOC); /* output a JSON representation of the home listing data retrieved */ ob_start("ob_gzhandler"); // compress the output header('Content-type: text/javascript'); print "{'homes' : "; array_walk_recursive($result_set, "cleanOutputFromXSS"); print json_encode( $result_set ); print '}'; $dbh = null; } catch (PDOException $e) { die('Unable to retreive home listing information'); } } function cleanOutputFromXSS(&$value) { $value = htmlspecialchars($value, ENT_QUOTES, 'UTF-8'); } ?> How would I begin converting this PHP code over to C, since C is both better on memory management (since you do it yourself) and much, much faster to execute?

    I have three script , from main - 1-script , I am calling other two scripts. so that I can execute both scripts parallely because it's taking too much time in sequential order. Only variables are different in the script. How can I merge script 2 & 3 in a single script so that I can call from the main script and it will run as parallel. 1 CompareCtrlM... Completed False localhost ######################... 3 CompareCtrlM... Completed True localhost ######################...

  • In app purchase on iphone.: How to receive your available products *before* someone may be able to b

    - by Thorsten S.
    Currently I am loading my supported products from a plist and after that I send a SKProductsRequest to guarantee that my SKProducts are still valid. So I set up the request, start it and get the response in: (void)productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response Now, so far all functions correctly. Problem: From calling the request until receiving the response it may last several seconds. Until that my app is already loaded and the user may be able to choose and buy a product. But because no products have been received, the available products are not in sync with the validated products - unlikely, but possible error. So my idea is to wait until the data is loaded and only continue when the list is validated. (Just a few seconds waiting...). I have a singleton instance managing all products. + (MyClass *) sharedInstance { if (!sharedInstance) sharedInstance = [MyClass new]; // Now wait until we have our data [condition lock]; while (noEntriesYet) // is yes at begin [condition wait]; [condition unlock]; return sharedInstance; } - productsRequest: didReceiveResponse: { [condition lock]; // I have my data noEntriesYet = false; [condition signal]; [condition unlock]; } Problem: The app freezes. Everything works fine if didReceiveResponse is completed before the sharedInstance is queried. There are different threads, the lock is working if wait is reached during didReceiveResponse, everything fine. But if not, didReceiveResponse is never called even if the request was sent. The lock is released, everything looks ok. I have tried to send the product request in a separate NSThread, with NSOperationQueue...without avail. Why ? What is happening ? How to solve the problem ?

  • With the advent of HTML 5, is there a point in using COMET anymore?

    - by h2g2java
    I am very tempted to use long wait http or periodic polling by the client to set up pseudo-sockets on the browser side, for an application that would be used publicly. But then on the 2nd thought, I am thinking HTML 5 is here. But on the 3rd thought, what is the percentage of browsers out there that remain non-HTML5 within 12 months, 24 months, 36 months? If there are at least 20% of browsers still incapable of HTML5, then I cannot depend on HTML5 because 20% of users not being able to access an application is a significant amount. What do you think, how would your advice be (to me and to developers in general)? Q1. Is there any point in rigging in COMET into an application anymore? I am thinking of gwt comet - http://code.google.com/p/gwt-comet/. Q2. Should we release a new public application within the next 2 months that is dependent on HTML5 sockets and tell non-HTML5 browser users "sorry, your browser version cannot access this application"? Or should we architect the apps to use communication like GWT RPC? Q3. I am also very distrustful of long wait http request. I have never used it before but I have a horrible feeling about it. I have been using 10 to 20 second client-side polling. Is long wait http request risky (risk of hanging a browser session)? Does long wait request present any additional security risk?

  • Syntactical analysis with Flex/Bison part 2

    - by Imran
    Hallo, I need help in Lex/Yacc Programming. I wrote a compiler for a syntactical analysis for inputs of many statements. Now i have a special problem. In case of an Input the compiler gives the right output, which statement is uses, constant operator or a jmp instructor to which label, now i have to write so, if now a if statement comes, first the first command (before the else) must be give out when the assignment of the if is yes then it must jump to the end because the command after the else isnt needed, so after this jmp then the second command must be give out. I show it in an example maybe you understand what i mean. Input adr. Output if(x==0) 10 if(x==0) Wait 5 20 WAIT 5 else 30 JMP 50 Wait 1 40 WAIT 1 end 50 END like so. I have an idea, maybe i can do it whith a special if statement like IF exp jmp_stmt_end stmt_seq END when the if statement is given in the input the compiler has to recognize the end ofthe statement and like my jmp_stmt in my compiler ( you have to download the files from http://bitbucket.org/matrix/changed-tiny) only to jump to the end. I hope you understand my problem.thanks.

  • Calling a jQuery plugin inside itself

    - by Real Tuty
    I am trying to create a comet like thing. I have a plugin that collects data from a php page. The problem is that i dont know how to call the plugin inside itself. If it were a function i could go like this: function j () {setTimeout(j(), 1000);}, but i am using a jQuery plugin. Here is my plugin code: (function($) { $.fn.watch = function(ops) { var $this_ = this, setngs = $.extend({ 'type' : 'JSON', 'query' : 'GET', 'url' : '', 'data' : '', 'wait' : 1000 }, ops); if (setngs.type === '') { return false; } else if (setngs.query === '') { return false; } else if (setngs.url === '') { return false; } else if (setngs.wait === '') { return false; } else if (setngs.wait === 0) { setngs.wait = 1000; } var xhr = $.ajax({ type : setngs.query, dataType : setngs.type, url : setngs.url, success : function(data) { var i = 0; for (i = 0; i < data.length; i++) { var html = $this_.html(), str = '<li class="post" id="post-' + data[i].id + '"><div class="inner"><div class="user">' + data[i].user + '</div><div class="body">' + data[i].body + '</div></div></li>'; $this_.html(str + html); } setTimeout($this_, 1000); } }); }; })(jQuery); where it says setTimeout($this_, 1000); this is where im having trouble. I don't know what to call the plugin as. $this_ is what I thought might work but I am wrong. That is what i need to replace. Thanks for your help.

  • Javascript Anonymous Functions and Global Variables

    - by Jonathan Swift
    I thought I would try and be clever and create a Wait function of my own (I realise there are other ways to do this). So I wrote: var interval_id; var countdowntimer = 0; function Wait(wait_interval) { countdowntimer = wait_interval; interval_id = setInterval(function() { --countdowntimer <=0 ? clearInterval(interval_id) : null; }, 1000); do {} while (countdowntimer >= 0); } // Wait a bit: 5 secs Wait(5); This all works, except for the infinite looping. Upon inspection, if I take the While loop out, the anonymous function is entered 5 times, as expected. So clearly the global variable countdowntimer is decremented. However, if I check the value of countdowntimer, in the While loop, it never goes down. This is despite the fact that the anonymous function is being called whilst in the While loop! Clearly, somehow, there are two values of countdowntimer floating around, but why?

  • How do I want untill is finished in C#?

    - by Grienders
    Let's say, I want to send a request to a server and get a result from it: private static string Send(int id) { Task<HttpResponseMessage> responseTask = client.GetAsync("aaaaa"); string result = string.Empty; responseTask.ContinueWith(x => result = Print(x)); responseTask.Wait(); // it doesn't wait for complemeting of response task return result; } private static string Print(Task<HttpResponseMessage> httpTask) { Task<string> task = httpTask.Result.Content.ReadAsStringAsync(); string result = string.Empty; task.ContinueWith(t => { Console.WriteLine("Result: " + t.Result); result = t.Result; }); task.Wait(); // it does wait return result; } Am I using task correct? I don't think so because Send() method return string.Empty all the time, while Print returns the correct value. What am I doing wrong? How do I get a result from a server?

  • Suggestions for opening the Rails toolbox to design a challenge game?

    - by keruilin
    How would you suggest designing a challenge system as part of a food-eating game so that it's automated as possible? All RoR tools, design patterns and logic are at your disposal (e.g., admin consoles, crontab, arch, etc.). Prize goes to whoever can suggest the simplest and most-automated design! Here are the requirements: User has many challenges. Badge has many challenges. (A unique badge is awarded for each challenge won.) Only one challenge can run at a time. Each challenge has a limited number of days that it runs. For example, one challenge can run 3 days, while another runs 7 days. Challenges can be seasonal. For example, "Eat 13 Pumpkins" only runs during the Fall. New challenges are added to the game on an ongoing basis. For example, a new challenge every week. Each challenge has a certain probability of being selected to run. For example, "Eat 10 Pies" challenge has 10% chance of being selected to run. As each new challenge is added to the database, I want the probabilities of running to change dynamically. I want to avoid the scenario where I'm manually updating a database field just to change the probability from 10% to 5%, for example. Challenges act like Easter eggs. Challenge icons pop-up at different places on the webpage. User is awarded a badge for successfully completing a challenge, but only when it's active. There is some wait time between each challenge. Between 1 and 7 days. Which wait time is random, but the probability of the wait time being short is high and the probability of it being a long wait time is low.
