• file_get_contents returns 403 forbidden

  - by absk

  I am trying to make a sitescraper. I made it on my local machine and it works very fine there. When I execute the same on my server, it shows a 403 forbidden error. I am using the PHP Simple HTML DOM Parser. The error I get on the server is this: Warning: file_get_contents(http://example.com/viewProperty.html?id=7715888) [function.file-get-contents]: failed to open stream: HTTP request failed! HTTP/1.1 403 Forbidden in /home/scraping/simple_html_dom.php on line 40 The line of code triggering it is: $url="http://www.example.com/viewProperty.html?id=".$id; $html=file_get_html($url); I have checked the php.ini on the server and allow_url_fopen is On. Possible solution can be using curl, but I need to know where I am going wrong.

• Python ctypes: loading DLL from from a relative path

  - by Frederick

  I have a Python module, wrapper.py, that wraps a C DLL. The DLL lies in the same folder as the module. Therefore, I use the following code to load it: myDll = ctypes.CDLL("MyCDLL.dll") This works if I execute wrapper.py from its own folder. If, however, I run it from elsewhere, ctypes goes looking for DLL in the current working directory and naturally fails. My question is, is there a way by which I can specify the DLL's path relative to the wrapper instead of the current working directory? This will enable me to ship the two together and allow the user to run/import the wrapper from anywhere.

• How to run a COM .dll on a remote server?

  - by PrgTrdr

  I have a legacy 3rd party COM .dll that is used to provide an Excel-callable interface to a proprietary database product. The .dll runs on the same physical machine as Excel. I have a need to execute the .dll (and the database it is calling) on a remote server while still maintaining simple Excel callability from the client. I'm totally confused by all the different MS technologies that seem to hint there is an easy way to do this. Can someone please point me in the right direction (easier is better)?

• Ampersand in JSON/PHP in POST

  - by svenkapudija

  I'm having a text field which is send via JSON and jQuery (wrapped with .toJSON function) to my server via AJAX and POST request. On PHP side I'm doing json_decode . Everything works but if I put ampersand (&) inside it splits up the POST parameter so its incomplete on PHP side (at least what var_dump($_POST) is writing out). Shouldn't the toJSON and json_decode do all the job (escaping)? I tried encodeURIComponent, & to &amp;, & to \u0026 and it's not working. What I'm doing wrong? AJAX call function execute() { this.setupUrl(); return $.ajax({ type: this.requestMethod, data: this.getDataParams(), url: this.url }); } function getDataParams() { if(this.data != undefined) { if(this.requestMethod == 'POST' || this.requestMethod == 'PUT') { return "data=" + $.toJSON(this.data); } else if (this.requestMethod == 'GET') { return this.data; } } else { return null; } }

• Sqlite + Java: table not updating

  - by Ben L

  I'm using a Java wrapper for SQLite called SQLiteJDBC - this may have some bearing on any answers... I have a table which I've displayed in a GUI, within that UI I have a button for the fields for an individual row of that table. When I save my changes I do this... Statement stmt = connection.createStatement(); stmt.execute("update 'tableName' set 'fieldName'=1 where userid=1"); int updateCount = stmt.getUpdateCount(); My connection is valid, I get no exceptions thrown and getUpdateCount() returns '1' indicating that one row has been updated. However my table is not updated. I've spent the last few hours trying to work out what's going on but I'm not having any luck. Help!!

  - by Kanags.Net

  I'm trying to copy a treeview nodes to treenodecollection for some other processing. When i execute the treeview.nodes.clear() in the next line, my treenodecollection is becoming null. Can you please tell me how to copy the treeview nodes to treenodecollection and keep the copies of the nodes even after calling Clear method of actual tree view nodes? TreeNodeCollection tnc = null; private TypeIn() { tnc = treeView1.Nodes; treeView1.Nodes.Clear(); //Now my tnc becomes null, but I want the tnc for future use. }

• MS SQL Server Job with precise timing

  - by TcKs

  Hi, I have a DB with game data (map, players, etc...) and I have a game core mechanics writen in T-SQL stored procedure. I need process game loop (via the stored procedure) every "X" seconds. I tried used the SQL Job, but when I set the interval to seconds, the SQL server stops responding. If I set the interval greater than one minute, all was ok. I need game loop precise in time, e.g. the game loop will run only once and will be executed every "X" precisely (tolerance should be less than one second). Can I do it with MS SQL Server capabilities? Or should I create a windows service which will repeatly execute game loop procedure? Or should I go another way? Thanks! EDIT: The game loop stored procedure takes less than the interval.

• Can I automatically attach to the lifecycle of ANY server-enabled HTML tag?

  - by Deane

  If a "server-enabled" HTML tag is in a Web form, like this -- <p runat="server"/> -- is there any way for me to attach to its rendering? I assume once they have runat="server", they must have a lifecycle of some kind. I'd like to attach some code to the rendering of any HTML tag so enabled. So, whenever a template author puts runat="server" on a tag, I can catch the PreRender (or anything else) and execute some code. Possible?

• Wpf button click when application window is not active

  - by byte

  I have a WPF application window with a button (ButtonA) which has a command binding to a View Model property. When another application is launched the focus is lost and application window is deactivated. Clicking ButtonA now doesn’t execute the command but instead only activates the window and sets the focus to the button. 2nd click is required to fire the command. The desired functionality is on click of ButtonA while the application window is not active, the application window activates and command associated with ButtonA is executed. I have also tried removing the command and adding a click handler for test purpose but this displays same behaviour. I appreciate any help with this issue.

• how to call a javascript function in the top frame?

  - by Rory

  This seems really simple, but how do I call a javascript function that's defined in the top-level html, from a child frame? top html doc - 1st level frame - 2nd level frame my top html doc has a function called testFn(). In the 2nd level frame I have a button with onclick="top.testFn();" but this doesn't call the testFn(). In Firebug if I use a watch to execute top.testFn(); it says TypeError: testFn() is not a function. Should this all just work - in which case it's a problem with my documents, or is there some other way to call functions in the top-level window?

• ASP.NET MVC Filters: How to set Viewdata for Dropdown based on action parameter

  - by CRice

  Hi, Im loading an entity 'Member' from its id in route data. [ListItemsForMembershipType(true)] public ActionResult Edit(Member someMember) {...} The attribute on the action loads the membership type list items for a dropdown box and sticks it in viewdata. This is fine for add forms, and search forms (it gets all active items) but I need the attribute to execute BASED ON THE VALUE someMember.MembershipTypeId, because its current value must always be present when loading the item (i.e. all active items, plus the one from the loaded record). So the question is, what is the standard pattern for this? How can my attribute accept the value or should I be loading the viewdata for the drop down in a controller supertype or during model binding or something else? It is in an attribute now because the code to set the viewdata would otherwise be duplicated in each usage in each action.

• Apache HTTPClient returns an empty page

  - by mariosangiorgio

  Hi, I am using the Apache HTTPClient for Java and I'm facing a really strange issue. Sometimes when I try to get a dynamically generated page it returns its actual content, but other times (with another parameter) all I get is a short sequence of \t,\r and \n. How could I track what's going on on the different cases in order to find where is the bug? My usage of the library is pretty straightforward, all I do is this few calls on an initialized HTTPClient object: String content = "/pageIwant.jsp?parameter=10101010"; HttpGet request = new HttpGet(content); HttpResponse response = client.execute(targetHost, request); HttpEntity entity = response.getEntity(); String page = EntityUtils.toString(entity);

• What is the fastest way to compare 2 rows in SQL?

  - by Swoosh

  I have 2 different databases. Upon changing something in the big one (i don't have access to), i get some rows imported in my databases in a similar HUGE table. I have a job checking for records in this table, and if any, execute a stored procedure, process and delete from table. Performance. (Huge amount of data) I would like to know what is the fastest way to know if something has changed using let's say 2 imported rows with 100 columns each. Don't have FK-s, don't need. Chances are, that even though I have records in my table, nothing has actually changed. Also. Let's say there is actually changed something. Is it possible for example to check only for changes inside datetime columns? Thanks

• jQuery: how to find first visible input/select/textarea excluding buttons?

  - by Artem

  I tried $(":input:not(input[type=button],input[type=submit],button):visible:first") but it doesn't find anything. What is my mistake? UPD: I execute this on $(document).load() <script type="text/javascript"> $(window).load(function () { var aspForm = $("form#aspnetForm"); var firstInput = $(":input:not(input[type=button],input[type=submit],button):visible:first", aspForm); firstInput.focus(); }); </script> and in the debug I can see that firstInput is empty. UPD2: I'm in ASP.NET page running under Sharepoint. I've found so far that for some elements it does find them (for fixed ones) and for some don't. :(

• Why can't I pass in a uniqueidentifier/GUID to a stored procedure

  - by chobo2

  Hi I have this SP USE [TestDB] GO /****** Object: StoredProcedure [dbo].[sp_test] Script Date: 06/12/2010 11:47:27 ******/ SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO CREATE PROCEDURE [dbo].[sp_test] @id uniqueidentifier AS BEGIN select * from TestTbl where ProductId= @id END I then went to the SP with ms sql 2005 and clicked execute. It comes up with a box where I entered in the GUID. I copied and pasted it straight from my test database. I get this error. Msg 102, Level 15, State 1, Line 5 Incorrect syntax near 'cac671b'. So why can't I sent in GUIDs? even ones that are copied right from the database and must be valid as they where allowed into the db.

• 42000 Syntax error in query when executing prepared statement

  - by Griff McGriff

  I have been pulling my hair out trying to swap my current script over to PDO. I have simplified the MySQL query for this example, but the error remains even with this version. $sql = 'SELECT * FROM :table WHERE lastUpdate > :appDate'; try{ $db = connect(); $stmt = $db->prepare($sql); $stmt->bindParam(':table', $table); $stmt->bindParam(':appDate', $appDate); foreach($tablesToCheck as $table){ $stmt->execute(); $resultset[] = $stmt->fetchAll(); } } catch(PDOException $e){ print 'Error!: '.$e->getMessage().'<br/>'; }//End try catch $stmt-errorInfo() returns: ( [0] => 42000 [1] => 1064 [2] => You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ''GroupName' WHERE lastUpdate > NULL' at line 1 )

• Calling C/C++ library function from PHP

  - by Anon. BlackBerry Developer

  We have a PHP web app running on a customer's machine. For an update, we have a bit of code in C that we'd like to include as a native opaque library along with the PHP web app. How does one go about calling a C/C++ lib. function from PHP? It cannot be assumed that the PHP app, called by the web server, has any sort of permission to call an exec(), eval(), or system() type of function to execute a C wrapper driver which in turn uses the C/C++ library, so it would need to be a direct C library use from within the PHP code.

• How to sort an NSMutableArray of objects by a member of its class, that is an int or float

  - by J. Dave

  I have a class (from NSObject) that contains: NSString name int position float speed I then create an array (NSMutableArray) of objects from this class. I would like to then sort the array by the 'speed' value, which is a float. I initially has the float value as an NSNumber and the int as NSInteger, and I was successfully sorting with: [myMutableArray sortUsingFunction:compareSelector context:@selector(position)]; where myMutableArray is my array of objects. here is the function: static int compareSelector(id p1, id p2, void *context) { SEL methodSelector = (SEL)context; id value1 = [p1 performSelector:methodSelector]; id value2 = [p2 performSelector:methodSelector]; return [value1 compare:value2]; } Now that I am using int instead of NSInteger, the above code does not work. Is there a more low-level command that I should be using to execute the sort? Thank!

• Fluent NHibernate ExportSchema without connexion string

  - by Vince

  Hi all, I want to propose to user a way to generate database table script creation. To do this for now i use NHibernate ExportSchema bases on a NHibernate configuration generated with Fluent NHibernate this way (during my ISessionFactory creation method): FluentConfiguration configuration = Fluently.Configure(); ... Mapping conf ... configuration.Database(fluentDatabaseProvider); this.nhibernateConfiguration = configuration.BuildConfiguration(); returnSF = configuration.BuildSessionFactory(); ... Later new SchemaExport(this.nhibernateConfiguration) .SetOutputFile(filePath) .Execute(false, false, false); fluentDatabaseProvider is a FluentNHibernate IPersistenceConfigurer which is needed to get proper sql dialect for database creation. When factory is created with an existing database, everything works fine. But what i want to do is to create an NHibernate Configuration object on a selected database engine without a real database behind the scene... And i don't manage to do this. If anybody has some idea.

• Need help fetching an array using prepared statments

  I have wrote the following code to fetch a string. But for some reason its only returning 1. I have doubled checked everything and it seems like its correct. I am not sure why its only returning 1? Any help here would be really appreciated! //Class Defined here function MenuCat($id){ $query = "SELECT menu_category_description FROM menu_categories WHERE id = ?"; $stmt = $this->db->prepare($query); $stmt->bind_param("i", $id); $stmt->execute(); $stmt->bind_result($menu_category_description); $row = $stmt->fetch(); return $row; } $display_category = $cat_des->MenuCat($id); echo $display_category

• Is it possible get the functionality of namespaces inside a class?

  - by CowKingDeluxe

  I have the following code: Public Class Form1 Private Function Step1_Execute() As Boolean Return Step1_Verify() End Function Private Function Step1_Verify() As Boolean Return True End Function Private Function Step2_Execute() As Boolean Return Step2_Verify() End Function Private Function Step2_Verify() As Boolean Return True End Function End Class What I would like to do is be able to separate the code, similar to the following (which obviously doesn't work): Public Class Form1 Namespace Step1 Private Function Step1_Execute() As Boolean Return Step1_Verify() End Function Private Function Step1_Verify() As Boolean Return True End Function End Namespace Namespace Step2 Private Function Step2_Execute() As Boolean Return Step2_Verify() End Function Private Function Step2_Verify() As Boolean Return True End Function End Namespace End Class I would like the functionality of namespaces inside of a class, as in something that would let me call Step2.Execute() instead of having to put Step2_ in front of a whole bunch of functions. I don't want to have to create separate classes / modules for step1, step2, etc. Is there a way that I can accomplish namespace functionality from inside a class?

• What can you do in the ant Task.init() method?

  - by skiphoppy

  I'm developing a few custom ant tasks that all need to initialize the same objects. I wanted to initialize those object's in a common superclass that extends from Task, in the init() method. But I see from the lifecycle of an ant task that init() gets called before the tasks child elements and attributes are set. So all of the data I need for initializing those objects is unavailable during init(), if I am reading right. So, why is init() called at this point? What do you even know that you could use in init()? What could it be used for? (And is there some other method that I can rely on to be called before execute(), but after my data is available?)

• understanding memory mapping in directx

  - by numerical25

  So my question is ... " When your using the mapping feature to write into a memory buffer, are you really just saving the whole procedure into a queue so directX executes it when finished with other tasks???" I ask this question because this is my perception of mapping when writing to a buffer. I just want to make sure my perception is correct. I understand that the monitor moves extremely slow in compared to the processor, and I am sure the processor can execute 10 times the amount the screen can refresh. So is this one of the reason you should map when writing to a buffer. so each procedure can be done in a orderly fashion. If someone could elaborate, that would be great. thanks

• Check if NFS share is mounted in python script

  - by Fabian

  I wrote a python script that depends on a certain NFS share to be available. If the NFS share is not mounted it will happily copy the files to the local path where it should be mounted, but fail later when it tries to copy some files back that were created on the NFS server. I'd like to catch this error specifically so I can print a useful error message that will tell the users of this script what they have to do. My first idea would be to execute mount using subprocess and then check the output for this nfs share. But I'm wondering if there isn't a nicer and more robust method of doing it.

• Can somehow show progress on file upload without using AJAX?

  - by nimo

  Let's say that I upload a file using a basic multipart post. The server then receives the request and starts to execute the server side code. Can I somehow in that state start to output the response and after some data is sent start to receive the file? Finally when the file is uploaded I output the rest of the response. If this is possible I can display file upload progress without using ajax? I guess this might depend on what I run server side. But let's assume that I have full network control.
