  • problem with generating PDF and session_start()

    - by gillian
    Hi All, I've been using PDF class produced by R&OS successfully in a number of recent developments. I'd like to use it in a page that performs a database query before generating a PDF (it's basically a summary of the session, so I'm using session_id() as part of the query) All is fine if I run this in Firefox - not fine in IE. I think the loading of session_start() is doing something with headers that's upsetting IE as it appears unable to load the page (comment off session_start and the page loads fine). I'm getting a little concerned as, on further investigation, it appears that R&OS is not supported ... bad newbie learning experience and I really don't want to have to try adopt another class system this late in the day. Have you any thoughts as to what I could try next? Thankx G

  • How to acquire the Context in an Adobe AIR Native Extension?

    - by rotaercz
    In the following line of code... ProgressDialog progressDialog = ProgressDialog.show(getBaseContext(), "LOADING_TITLE", "LOADING_MESSAGE"); In place of getBaseContext() I've tried... getApplicationContext() this NativeActivity.this (NativeActivity)getApplicationContext() Among others. I'm not sure why it's not working. In the NativeExtensionContext which extends FREContext I am passing the activity using getActivity() to NativeActivity. Everything works well but I get a "Nullpointerexception" or “android.view.WindowManager$BadTokenException: Unable to add window — token null is not for an application” when I try I try to get a reference to the Context. Anyone with experience using Adobe AIR Native Extensions and/or Android Java would be great.

  • pdo connection scope

    - by Scarface
    Hey guys I have a connection class I found for pdo. I am calling the connection method on the page that the file is included on. The problem is that within functions the $conn variable is not defined even though I stated the method was public (bare with me I am very new to OOP), and I was wondering if anyone had an elegant solution other then using global in every function. Any suggestions are greatly appreciated. CONNECTION class PDOConnectionFactory{ // receives the connection public $con = null; // swich database? public $dbType = "mysql"; // connection parameters // when it will not be necessary leaves blank only with the double quotations marks "" public $host = "localhost"; public $user = "user"; public $senha = "password"; public $db = "database"; // arrow the persistence of the connection public $persistent = false; // new PDOConnectionFactory( true ) <--- persistent connection // new PDOConnectionFactory() <--- no persistent connection public function PDOConnectionFactory( $persistent=false ){ // it verifies the persistence of the connection if( $persistent != false){ $this->persistent = true; } } public function getConnection(){ try{ // it carries through the connection $this->con = new PDO($this->dbType.":host=".$this->host.";dbname=".$this->db, $this->user, $this->senha, array( PDO::ATTR_PERSISTENT => $this->persistent ) ); // carried through successfully, it returns connected return $this->con; // in case that an error occurs, it returns the error; }catch ( PDOException $ex ){ echo "We are currently experiencing technical difficulties. We have a bunch of monkies working really hard to fix the problem. Check back soon: ".$ex->getMessage(); } } // close connection public function Close(){ if( $this->con != null ) $this->con = null; } } PAGE USED ON include("includes/connection.php"); $db = new PDOConnectionFactory(); $conn = $db->getConnection(); function test(){ try{ $sql = 'SELECT * FROM topic'; $stmt = $conn->prepare($sql); $result=$stmt->execute(); } catch(PDOException $e){ echo $e->getMessage(); } } test();

    i have the following code below but sometime the "serving_description" tag isn't there. Right now i just put a try catch around it but i wanted to find out if there was a cleaner way to handle this scenario.

  • Referencing a different project in the same assembly, different namespaces

    - by Redburn
    I have two projects : Menu and Module and they are both in the same namespace foobar. I am currently referencing the module project from the Menu project to open up certain controls on a tab control in my menu. However I need to launch a new control from one of my controls which is located in the Module project. When I try referencing the menu project, it does not show up in my intellisense when I try to reference it with a using. Am I doing something wrong logically here? Here is an example of what it is : Project Menu Public Void LaunchWPFControl(string pHeader,string pPath) { //Code goes here to launch a WPF control in the browser } Project Module //What I would love to do but doesn't work Using Menu; ... ... ... private void dgModule_MouseDoubleClick(object sender, MouseButtonEventArgs e) { Menu.LaunchWPFControl("Accounts","AccountsControl"); }

  • Is there any memory restrictions on an ASP.Net application? HttpHandler?

    - by tpower
    I have an ASP.Net MVC application that allows users to upload images. When I try to upload a really large file (400MB) I get an error. I assumed that my image processing code (home brew) was very inefficient, so I decided I would try using a third party library to handle the image processing parts. Because I'm using TDD, I wanted to first write a test that fails. But when I test the controller action with the same large file it is able to do all the image processing without any trouble. The error I get is "Out of memory". I'm sure my code is probably using a lot more memory than it needs to but I just want to know why my test passes. The other difference is that I'm using SWFUpload which is not used with the test. Could this be the cause?

  • python [lxml] - cleaning out html tags

    - by sadhu_
    from lxml.html.clean import clean_html, Cleaner def clean(text): try: cleaner = Cleaner(scripts=True, embedded=True, meta=True, page_structure=True, links=True, style=True, remove_tags = ['a', 'li', 'td']) print (len(cleaner.clean_html(text))- len(text)) return cleaner.clean_html(text) except: print 'Error in clean_html' print sys.exc_info() return text I put together the above (ugly) code as my initial forays into python land. I'm trying to use lxml cleaner to clean out a couple of html pages, so in the end i am just left with the text and nothing else - but try as i might, the above doesnt appear to work as such, i'm still left with a substial amount of markup (and it doesnt appear to be broken html), and particularly links, which aren't getting removed, despite the args i use in remove_tags and links=True any idea whats going on, perhaps im barking up the wrong tree with lxml ? i thought this was the way to go with html parsing in python?

    In python, is there a way to exit a class after testing a condition, without exiting out of python? say i have the class class test(): def __init__(self): self.a = 2 def create_b(self): self.b = 3 def does_b_exist(self): if <self.b doesnt exist>: #terminate self.b += 1 try/except` doesnt work since the rest of the program doesnt terminate after failing. im basically trying to catch an error, and do what python does when it shows you errors, but i cant figure out how to do it

  • How to delete a post in Nhibernate?

    - by marko
    I try to delete a post in NHibernate but nothing happens. Updating, selecting and inserting new items works fine but when I try to delete nothing happens. IQuery query = session.CreateQuery("from Color where name like '%" + TextBox2.Text.Trim() + "%'"); Color color = query.List<Color>()[0]; session.Delete(color); Edit: I forgot to call the flush method. Now works fine. Like this: session.Flush();
