• X-Domain and P3P Headers

  - by Jackson

  Hi, I have a website A.com and a domain at B.com with a widget inside an iframe getting data from A.com. I want to allow x-domain cookies to be passed from a.com to inside the iframe using ASP.NET My understanding is that - I can do this in IE using P3P Headers - such that the A.com cookie is passed to the iframe and session | cookie data is preserved. The P3P headers have to be sent from the A.com and from the iframe. Is this correct ? In dev, my understanding is if I "accept all cookies" in IE - then P3P headers won't matter anyway and so this should all just work. If I put on Medium Security then P3P is required.

• Filling data in FormView from different tables

  - by wacky_coder

  Hi, I am using a FormView in an online quiz page for displaying the questions and RadioButtons (for answers) http://stackoverflow.com/questions/2438219/online-quiz-using-asp-dot-net Now, I need to pick the questions according to a TestID and a particular Set of that Test. The testid and the set_number would be passed using Session variables. I'm having 3 testIDs and 3 Sets per TestID and, thus, am using 9 tables to store the Questions, the Options and the correct answer. I need help on how to set the FormView so that it extracts the questions from a particular table only. Do I need to use a StoredProcedure ? If yes, how? PS: If I use only one table to store all the questions from each Set and for each TestID, I can do that, but I'd prefer using separate tables.

• sending instant messages through python (msn)

  - by code_by_night

  ok I am well aware there are many other questions about this, but I have been searching and have yet to find a solid proper answer that doesnt revolve around jabber or something worse. (no offense to jabber users, just I don't want all the extras that come with it) I currently have msnp and twisted.words, I simply want to send and receive messages, have read many examples that have failed to work, and msnp is poorly documented. My preference is msnp as it requires much less code, I'm not looking for something complicated. Using this code I can login, and view my friends that are online (can't send them messages though.): import msnp import time, threading msn = msnp.Session() msn.login('[email protected]', 'XXXXXX') msn.sync_friend_list() class MSN_Thread(threading.Thread): def run(self): msn.start_chat("[email protected]") #this does not work while True: msn.process() time.sleep(1) start_msn = MSN_Thread() start_msn.start() I hope I have been clear enough, its pretty late and my head is not in a clear state after all this msn frustration. edit: since it seems msnp is extremely outdated could anyone recommend with simple examples on how I could achieve this? Don't need anything fancy that requires other accounts.

• On Windows XP, programmatically set Pagefile to "No Paging File" on single c: drive

  - by NBPC77

  I'm trying to write a C#/.NET application that optimizes the hard drives for our XP workstations Set pagefile to "No paging file" Reboot Run a defrag utility to optimize the data and apps Create a contiguous page file Reboot, run pagedefrag from Sysinternals I'm really struggling with #1. I delete the following key: SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\PagingFiles Upon reboot, the System Control Panel shows "No page file", but c:\pagefile.sys still exists and its in use by the SYSTEM process so I can't delete it and I can't optimize HD. I tried using PendingFileRenamingOperations and that bombs out too. I tried using WMI: Win32_PageFileSetting, but that only lets you set sizes (not zero--defaults to 2MB). Of course, if I do the manual steps outlined above, it works. I think I need an API call to make this happen.

• adding SSL to microchip Generic TCP server application

  - by Surjya Narayana Padhi

  Hi, Has anybody upgraded the code of generic tcp server application provided by Microchip to SSL? I added new listener port to existing server socket. But then also its not TCPPutIsReady state. When I tried to connect through ssh client Tera Term its asking for username and password. But does it required for client to provide username and password? I a bit new to SSL. So please let me know the steps to connect to any ssl server using Tera Term. Another doubt is that can i use a TCP server socket without using http or ftp or telnet session?

• Problem with between join for sqlalchemy orm relation.

  - by Gary van der Merwe

  I'm trying to create a relation that has a between join. Here is a shortish example of what I'm trying to do: #!/usr/bin/env python import sqlalchemy as sa from sqlalchemy import orm from sqlalchemy.engine.base import Engine from sqlalchemy.ext.declarative import declarative_base metadata = sa.MetaData() Base = declarative_base(metadata=metadata) engine = sa.create_engine('sqlite:///:memory:') class Network(Base): __tablename__ = "network" id = sa.Column(sa.Integer, primary_key=True) ip_net_addr_db = sa.Column('ip_net_addr', sa.Integer, index=True) ip_broadcast_addr_db = sa.Column('ip_broadcast_addr', sa.Integer, index=True) # This can be determined from the net address and the net mask, but we store # it in the db so that we can join with the address table. ip_net_mask_len = sa.Column(sa.SmallInteger) class Address(Base): __tablename__ = "address" ip_addr_db = sa.Column('ip_addr', sa.Integer, primary_key=True, index=True, unique=True) Network.addresses = orm.relation(Address, primaryjoin=Address.ip_addr_db.between( Network.ip_net_addr_db, Network.ip_broadcast_addr_db), foreign_keys=[Address.ip_addr_db]) metadata.create_all(engine) Session = orm.sessionmaker(bind=engine) Network() I you run this, you get this error: ArgumentError: Could not determine relation direction for primaryjoin condition 'address.ip_addr BETWEEN network.ip_net_addr AND network.ip_broadcast_addr', on relation Network.addresses. Do the columns in 'foreign_keys' represent only the 'foreign' columns in this join condition ? The answer to that question is Yes, but I cant figure out how to tell it that

• Custom fine-grained claims based authorization system in ASP.NET MVC - wheres and hows

  - by BuzzBubba

  So, I'd like to implement my own custom authorization system in MVC2. If I'd have to create a global class, where do I instantiate it? Can HttpContext be extended with my own additions and where do I do that? Should I use Authorization filters for rights validation or ActionFilters or do it within an action? Can ActionFilter pass any data to the action itself? Previously (in WebForms) I was using a Session object where I would put a serialized object containing essential user data (account id and a list of roles and rights) and I'd extend my own Page class.

• Facebook status.get API throws 500 HTTP status code

  - by Charles Prakash Dasari

  I have an APP that calls Facebook status.get method via the REST server - restserver.php using session key method. This app works fine for most of the users, but for one user I consistently receive HTTP 500 status code. Since this doesn't have any specific Facebook error message, it is almost impossible for me to debug this. Anyone faced a similar problem? What could be wrong with this user account? I checked the privacy options that I could think of and they look fine. Also, for the same user, I can use friends.get method without any problem. EDIT: I tried in Facebook forums as well, but it was of no use. Any pointers in the direction towards debugging/troubleshooting this problem are also appreciated.

• How do I check out Eclipse projects from CVS using the command line

  - by Jeff James

  Hi. I'm trying to check out the Mylyn project from Eclipse. However, I can't use Eclipse to check out the projects and am having to do it via the command line. I'm behind a firewall so am basing my attempt on http://wiki.eclipse.org/CVS_Howto#CVS_and_firewalls. I'm not very familiar with CVS. When I run my CVS command, it fails to connect: cvs -td :pserver:[email protected]:443/cvsroot/tools checkout mylyn -> main: Session ID is w4PO5KiMwQmaD6uu -> main loop with CVSROOT=/cvsroot/tools -> safe_location( where=(null) ) -> open_connection_to_server (:pserver:[email protected]:443/cvsroot/tools) -> Connecting to proxy.eclipse.org(206.191.52.48):443. cvs [checkout aborted]: unrecognized auth response from proxy.eclipse.org: SSH-1.99-OpenSSH_4.2 Can anyone tell me what I'm doing wrong?

• Varnish, hide port number

  - by George Reith

  My set up is as follows: OS: CentOS 6.2 running on an OpenVZ virtual machine. Web server: Nginx listening on port 8080 Reverse proxy: Varnish listening on port 80 The problem is that Varnish redirects my requests to port 8080 and this appears in the address bar like so http://mysite.com:8080/directory/, causing relative links on the site to include the port number (8080) in the request and thus bypassing Varnish. The site is powered by WordPress. How do I allow Varnish to use Nginx as the backend on port 8080 without appending the port number to the address? Edit: Varnish is set up like so: I have told the Varnish daemon to listen to port 80 by default.

• CSRF error when trying to log onto Django admin page with w3m on Emacs23

  - by Vernon

  I normally use Firefox and have had no problems with the admin page on my Django website. But I use Emacs23 for writing my posts, and wanted to be able to use w3m in Emacs to copy the stuff across. When I try to log into my admin pages, it gives the CSRF error: CSRF verification failed. Request aborted. Help Reason given for failure: No CSRF or session cookie. ... Is there a way that I could get w3m to work with my admin page? I am not sure if the problem lies with the way the admin is set up on Django or with the Emacs or w3m settings.

• How to receive userinfo with google adwords api libraries

  - by PatrickvKleef

  I'm using the Google Adwords API libraries and I would like to receive the userinfo of the logged in user. I added the userinfo scope as followed: googleAdwordsUser = new AdWordsUser(); string oauth_callback_url = HttpContext.Current.Request.Url.GetLeftPart(UriPartial.Path); googleAdwordsUser.OAuthProvider = new AdsOAuthNetProvider("https://adwords-sandbox.google.com/api/adwords/ https://www.googleapis.com/auth/userinfo.email", oauth_callback_url, Session.SessionID); When the callback url is called, I'm trying to get the users emailaddress, but it isn't working, the error 'The remote server returned an error: (401) Unauthorized.' is thrown. string url = @"https://www.googleapis.com/oauth2/v2/userinfo?access_token=" + token; HttpWebRequest objRequest = (HttpWebRequest)WebRequest.Create(url); objRequest.Method = "GET"; HttpWebResponse objResponse = (HttpWebResponse)objRequest.GetResponse(); string result = string.Empty; using (StreamReader sr = new StreamReader(objResponse.GetResponseStream())) { result = sr.ReadToEnd(); } Does somebody knows how to fix this? Thanks.

• Templated Control databinding to custom properties

  - by Dan Wray

  Is there some trick that I'm missing here? I've created a templated control, very simple. One single property on it, and I'd like to databind from the (viewmodel/datacontext of the) page in which it's hosted to a custom property on the control. The property will eventually be a vector type object, defining the position of the control, however in an attempt to get this to work I've tried reducing it to a basic string property. Each time I'm faced with "Set property 'SimpleGame.Classes.Sprite.Property' threw an exception.". I can't even catch the exception in a debug session, the set property code is not being executed. Do I need to use a dependency / attached property or something? I wouldn't have thought so...

• MySql: Select all entries with count...

  Hey guys quick question, I have a query that I want to count all entries it finds, and select all so when I use while($row=mysql_fetch_assoc($query)){ it will list all entries. The problem I am encountering is that while, all the entries are successfully counted and the right number is listed, only the latest entry is select and listed when I echo $row['title']. If I delete , COUNT(*) as total then it selects all but I was wondering if it was possible to use count and select *. I was wondering if anyone knew what I am doing wrong?

• Fluent NHib causing visual studio 2010 hanging at runtime

  - by Berryl

  Just installed and migrated a 2008 solution on Vista ultimate 64 and .net 4.0. Everything builds and tests run surprisingly well but I got the hang description below while trying to run the app under SQLite. It turns out that the hang has got something to do when the call is made for FNH to build the session factory during a run, the only feedback I get is that the database wasn't configure properly without any inner exception. The strange part is that the exact code works perfectly under tests. Any clues? Description: A problem caused this program to stop interacting with Windows.

• BDE, Delphi, ODBC, SQL Native Client & Dead lock

  - by EspenS

  Hi. We have some Delphi code that uses the BDE to Access SQL Server 2008 through the SQL Server Native Client ODBC driver (2005 version). Our issue is that we're experiencing some deadlock issues in a loop doing inserts to multiple tables. The whole loop is done within a [TDatabase].StartTransaction. Looking at the SQL Server Profiler we clearly see that at one point during the loop the SPID (Session ID?) change, and then we naturally end up with a deadlock. (Both SPID doing inserts to the same table) It seems like the BDE at some point does a second connection to the DB... (Although I would love to skip the BDE, it's currently not possible. ) Anyone with experiences to share?

• How to force client to switch RTP transport from UDP to TCP?

  - by Cipi

  If the client wants to watch a stream that is on my RTSP server, it first tries to setup a stream through the UDP protocol. How can I tell it that my server only supports RTP/AVP/TCP and that it should switch transports? I want to terminate the UDP support on my server, but all the clients first try to SETUP the session over UDP, and later they do so over TCP... and I want to switch them to TCP as soon as possible in RTSP protocol. How can I do that?

• Are JSF 2.x ViewScoped Beans Thread Safe?

  - by Mark

  I've been googling for a couple hours on this issue to no eval. WELD docs and the CDI spec are pretty clear regarding thread safety of the scopes provided. For example: Application Scope - not safe Session Scope - not safe Request Scope - safe, always bound to a single thread Conversation Scope - safe (due to the WELD proxy serializing access from multiple request threads) I can't find anything on the View Scope defined by JSF 2.x. It is in roughly the same bucket as the Conversation Scope in that it is very possible for multiple requests to hit the scope concurrently despite it being bound to a single view / user. What I don't know is if the JSF implementation serializes access to the bean from multiple requests. Anyone have knowledge of the spec or of the Morraja/MyFaces implementations that could clear this up?

• how to match a regulas expresion like (%i1) in python pexpect

  I want to use maxima from python using pexpect, whenever maxima starts it will print a bunch of stuff of this form: $ maxima Maxima 5.27.0 http://maxima.sourceforge.net using Lisp SBCL 1.0.57-1.fc17 Distributed under the GNU Public License.

• Microsoft Business Intelligence. Is what I am trying to do possible?

  - by Nai

  Hi guys, I have been charged with the task of analysing the log table of my company's website. This table contains a user's click path throughout the website for a given session. My company is looking to understand/spot trends based on the 'click paths' of our users. In doing so, identify groups of users that take on a certain 'click path' based on age/geography and so on. As you can tell from the title, I am completely new to BI and its capabilities so I was wondering: Are our objectives attainable? How should I go about doing this? I am currently reading books online as well as other e-books I have found. All signs seem to suggest this is possible via sequence clustering. Although the exact implementation and tweaks involved are currently lost on me. Therefore, if anyone has first hand experience in such an undertaking, I would be awesome if you could share it here. Cheers!
