• How to speed up request/response to django using apache or another solution?

  - by jbcurtin

  Hey all, I'm mainly a developer, but every now and again I jump into the sys-admin position. For the most part I've gotten away with deploying php and python apps using apache. I write today because I'm starting to research faster alternatives to apache, yet still have some of the core features I require like put and delete methods and the ability to connect to a socket via apache. ( This I have not tried, but might be a nice whistle if I ever employ comet on my apps. ) As you've probably guessed, I use javascript exclusively for all my websites utilizing deep linking for SEO support. The main areas that I'm looking to increase performance is the connection between the django apps and the web server to the client response. Every day I work my best to keep the smallest memory foot print as possible, however I am getting to the end of my rope when it comes to working with apache. In general, keep in mind that I'm just starting this research so I'm looking more for material to read then solutions at this moment. My main questions: Am I missing something about apache that makes it faster then everything else? What would be a good server environment to deploy just static files one? What are some of the leading open-source and paid alternatives?

• Fill down in Excel, but based on multiple values

  - by Jenn D.

  I have spreadsheets (not created by me) that have blank entries in one column where they should really have data. I want to take every empty cell and fill it with the nearest value above it. I'm looking for as little manual intervention as possible, because I'll have to do it repeatedly. I thought some previous version of Excel, or maybe another spreadsheet from the distant past, would do this by default -- that is, if you selected the column with foo and bar, and chose the equivalent of "fill down", you would get what's in the WANT column. What I actually get in Excel is the GET column. HAVE: WANT: GET: foo 1 foo 1 foo 1 2 foo 2 foo 2 bar 1 bar 1 foo 1 2 bar 2 foo 2 3 bar 3 foo 3 I'm worried that this might need a macro to be done properly. I used to be a whiz with Excel macros, and then suddenly they were all in VB. My fallback position will be to dump the whole thing to CSV and write a Python script, but if there's any way to do it in Excel that would be much preferable. Even if it involves a couple of different manual steps, that's fine; just not one step per group of lines. That is, a process of "copy the column, do X to it, cut and paste it back" would work, but "do X for each occurrence of foo or bar" won't. The files are too big for that. Any thoughts are appreciated!

• Setting umask for all users

  - by Yarin

  I'm trying to set the default umask to 002 for all users including root on my CentOS box. According to this and other answers, this can be achieved by editing /etc/profile. However the comments at the top of that file say: It's NOT a good idea to change this file unless you know what you are doing. It's much better to create a custom.sh shell script in /etc/profile.d/ to make custom changes to your environment, as this will prevent the need for merging in future updates. So I went ahead and created the following file: /etc/profile.d/myapp.sh with the single line: umask 002 Now, when I create a file logged in as root, the file is born with 664 permissions, the way I had hoped. But files created by my Apache wsgi application, or files created with sudo, still default to 644 permissions... $ touch newfile (as root): Result = 664 (Works) $ sudo touch newfile: Result = 644 (Doesn't work) Files created by Apache wsgi app: Result = 644 (Doesn't work) Files created by Python's RotatingFileHandler: Result = 644 (Doesn't work) Why is this happening, and how can I ensure 664 file permissions system wide, no matter what creates the file? UPDATE: I ended up finding a cleaner solution to this on a per-directory basis using ACLs, which I describe here.

• What mobile phones are viable for a "nerdy" person? [closed]

  - by Blixt

  This community wiki is for determining a list of good mobile phone choices if you are "nerdy" (definition follows.) As a point of reference, the almost two years old N95 8GB will be used. Mostly because that's what I can most relate to since I've had it since it came out. Today, iPhone and other modern mobile phones really out-shine it in usability and interface. However, it still does everything I want it to do (and here's the definition of "nerdy"; modify as needed): Syncs contacts, calendar, tasks and mail in the background Can run multiple installable applications in the background (Google Maps with Latitude, for example) Good amount of space for music etc. Lets you develop your own little toy applications (Python; not to mention it can also run an Apache server with a public URL!) Tethering! Supports Flash (maybe not very important, but it has its uses) Has a manufacturer that believes in the nerdiness! (The people at Nokia Labs make lots of cool stuff and share early versions with the community and are generally open) A high resolution screen (at least 320x240) Special hardware features such as an accelerometer and GPS What's missing from the N95 8GB but still qualifies as good, "nerdy", qualities: 7.2 Mbit/s (or faster) internet through HSDPA or HSPA+. A good web browser that can do most of the stuff a desktop browser can (especially render sites properly and run JavaScript correctly) Touch (especially multi-touch) More special hardware features such as a compass Intuitive and fluent user interface (Shiny stuff) Ability to configure it to trust root certificates of my own choice A processor fast enough to run Quake 3! =)

• More advanced 'Apple Automator' like software?

  - by OrangeBox

  What I'm looking for is a program similar to Automator or A Better Finder Rename but more extensive / advanced. In my situation we have two files with the same name, one is a MOV the other an XML. We want to use some of the metadata within the XML to rename both files. Then we want to re-arrange the contents of the XML file so that it is compatible with another piece of software we use (I think this process is called mapping?) Essentially some software that takes a bunch of variable from existing file and performs file actions to them. I imagine this would be an easy task using apple-script, but I'm wondering if there is a OSX application similar to Automator that can do the above? Questions are: Is there software that can do the above? Could Automator achieve this? What is the technical name of this kind of process? If no such software exists, what would be the best kind of script to use? eg. Make an Apple Script, python script etc.

• Postgresql Data Aggregation over WAN Securely

  - by Zach

  Hey guys, Need some advice on how to proceed with this situation: My current scenario is that I have several postgresql (50+) boxes deployed throughout various locations and data centers and a beefy postgresql box setup at a homebase location. All of the deployed boxes have identical database layouts. I'm looking for a solution that would allow for a few things. I realize some of these options overlap and some might only contain mutually exclusive solutions. However, I'm interested to hear your thoughts :) Remotely query the deployed boxes and pull the results back to the homebase box for processing. Nightly (remote) "sync" or dump the deployed boxes' databases to a master database on the homebase box. Remotely push a table entry to all of the deployed boxes from the homebase box. Ensure security of data in transit, and remotely deployed boxes. Up to this point I've been floating on a homebrew multithreaded python/perl system that SSH's into these boxes remotely, which are ACL'ed off to the homebase server and pulls (or pushes) the raw query results over the ssh connection. I have even touched #2 (remote syncing) as I know that would get nasty really quick. I'm interested in any ideas for a more elegant solution that can scale up and stick to my FreeBSD/Linux environment.

• Linux Distro - GUI similar to Windows

  - by DeaconDesperado

  I am in the process of refurbing several older laptop machines for use by a couple college guys we have in training to learn basic web development in python. These are students who intern at my company and are hoping to do some work when the summer comes building simple client-oriented webapps (learning the basics of OOP, MVC webapp design in flask, etc.). We're trying to function as the "practical" side of their education. I would like to get them set up on these machines we have sitting about, but I'd like to use a linux distro that would have a gui that closely approximates what they are being compelled to use at school (windows.) I don't really have much of a preference as far as GUI goes since much of what we'll be learning together is accomplished on the command line. I just see this as an easier adjustment for them while they are still reliant on a graphical environment. In the past I'd go straight for Ubuntu, but since they started using the Unity GUI the responsiveness overall can be pretty clunky on older machines, especially since these machines (there are four of them) run the gambit on specs (though all are at least 1.0Ghz and none have anything better than basic integrated video.) Has anyone had to setup a similar working environment in Mint, bare Debian or Zorin? Thanks.

• PassEnv does not find ENV variables

  - by quodlibetor

  I've got this /etc/profile.d/myfile.sh: export MYVAR=myval I also have a PassEnv MYVAR line in a <virtualhost> section of an apache conf dir. That lets me do things like: $ echo $MYVAR myval $ python >>> import os; os.getenv('MYVAR') 'myval' $ sudo echo $MYVAR myval $ sudo -i root# echo $MYVAR myval But then, despite that being the case I get: root# /sbin/service httpd restart /sbin/service httpd restart Stopping httpd: [ OK ] Starting httpd: [Mon Oct 22 14:44:02 2012] [warn] PassEnv variable MYVAR was undefined [ OK ] And all of my attempts to access MYVAR from within my wsgi scripts just don't work. Thoughts? Am I doing something obviously wrong? EDIT for more detail I've got a swarm of computers/VMs and a swarm of developers working on a swarm of projects. I need a simple central place to keep environment information, the most common is the "environment" (dev/stage/prod). The scheme that we've got (modifying *.wsgi programmatically) is turning out to be more fragile than we'd like. The main options that I see are: put things in the shell environment put things in other config files Getting things into the shell environment is the best, because we won't need to write yet more duplicated "what is my environment" code.

• How to create a WHM/cPanel account, without creating a new sub-domain?

  - by Cyclops

  I have a basic VPS (full root access), with WHM/cPanel, and am learning the ropes. I'm trying to create a new account for an existing domain (mysite.com), and so far WHM won't let me - it either wants a sub-domain or fake domain, but won't allow two accounts for one domain. In the beginning, there was only the root account, and it wouldn't let me login to cPanel - a quick chat with tech support, and I am informed that I need to create a second account, which I did. So now I have an account, call it ns1me, for domain mysite.com. Now I want to create a django account. I go through the same process, but WHM won't allow me to use mysite.com as the domain for django. The docs recommend a sub-domain, so I fill the box in with django.mysite.com. I then realize that has actually created a sub-domain - going to django.mysite.com shows me its home directory, along with helpful information about what version of Apache, Python, and other mods its running (thanks, Apache). I really don't want a sub-domain, so that's out. Another chat with tech support, and they recommend a fake domain name, as it won't create anything. Sure enough, using a domain of djangomysite.com works, and WHM allows me to create a django account. But of course, I can't send email to [email protected] (where I could to [email protected]). What I want, is to be able to create a second account, associated with mysite.com (so I can run cPanel logged in as django, send email to [email protected], etc) - without creating a whole new sub-domain, or fake domain.

• Where is SQLite on Nokia N810? How to get?

  - by klausnrooster

  I need SQLite3 with the TCL interface for a simple command-line app I use on all my PCs and want to use on my new (to me) Nokia N810. But "find" does not find any SQLite on the Nokia N810. Several apps use it, supposedly, like the maps/gps (poi.db), and others. I got sudo gainroot before using find, tried with wildcards * and dot . No luck. I guess it's embedded in the apps that use it? The N810's app manager doesn't offer SQLite. Apt-get has it and then fails with error: "Unable to fetch some archives, ..." The "update" and "--fix-missing" options do not help. I don't really want to get scratchbox and compile SQLite and TCL extension for it from sources. I looked at README and it seems like it might be straightforward. However [1] it's not clear what scratchbox download I would need (there are dozens in the Index of /download/files/sbox-releases/hathor/deb/i386), [2] I've never compiled any C sources successfully before, [3] and the whole mess entails a lot of learning curve for what is a very small one-off personal project. http://www.gronmayer.com/ has a few (sqlite (v. 2.8.17-4), libsqlite0 (v. 2.8.17-4), and libsqlite0-dev (v. 2.8.17-4)) but they appear to part of some huge package, may or may not include the TCL interface, ... and no I don't want to port my tiny app to Python. Is there some option I've overlooked? Must I get scratchbox and compile for ARM myself? Thanks for your time.

• Different font SIZES in a Text Editor, based on Script(Alphabet) type (ie. per Unicode Code-Block)

  - by fred.bear

  Some non-Latin-based scripts(alphabets) have more detail in their glyphs than do the Latin-based-script equivalents, and typically need a larger font to give the same degree of legibility (resolution-wise). Sometimes, both script types need to be present in the same file. Notepad++ allows different font SIZES (and colour, etc) courtesy of syntax-highlighting. This allows me to display larger-fonted non-Latin-based script in a // BIG-FONT comment. Although this has been quite handy for me in some situations, it is quite limited. A Word Processor can handle this scenario, but I'm not interested in that. I want a nice simple(?) plain(?) Text Editor to do it... on a per script-type basis... eg. mixing Latin-1 and Devanagari (and Mandarin, and ... Such a thing may not exits, but Notepad++ has shown that a simple(?) plain(?) Text Editor is capable of it. Does anyone know of such a Text Editor? ...Q. Why not a Word Processor? ...A. Because GCC and Python don't like that format! but UTF-8 is fine.

• Dynamic DataGrid columns in WPF DataGrid based on the underlying set of data (and their type)

  - by StatsMan

  Hello everyone, I've got kind of a conceptual question. I am in the process of wrapping some statistics classes I wrote into WPF. For that I have two DataGrid(-Views, currently in WinForms). In one DataGrid each row represents a column in the other. There I can set-up different variables (as in mathematical/statistical variables) with fields like "Header", "DataType", "ValidationBehaviour", "DisplayType". There I can also set-up how it should be displayed. Some Columns can automatically be set to ComboBoxColumns, some TextBoxColumns, and so on and so forth. So, now once I've set-up these Columns I can go to the other grid and enter my data. I may, for instance, have generated (in grid 1) one Column called "Annual Gross Salary" with input of numerical values. Another Column called "Education" with "0=NoEducation", "1=College Level", "3=Universitary" etc. These labels are displayed as text in the combobox and my statistics engine behind then selects the respective value (0-3) for calculations (i.e. ordinal, nominal variables). Sooo. In WinForms I could basically generate all the columns by hand in code and then add my data in the respective cells/rows. Now in WPF I thought that must be easy to realise. However, yesterday I got started with ICustomPropertyDescriptor which (maybe I was too thick) didn't give me the results I was looking for. Basically, I just need to be able to dynamically generate columns (and rows) with different Layout, Controls (ComboBox, simple Input, DateTimes) based on the data that I have. But I don't really know how to go about it? So here in summary: DataGrid 1 Purpose is to display columns that have been specified in DataGrid 2 In rows, the user can add any kind of data in the rows below the columns that is allowed as to the columns specifications DataGrid 2 Each row in this grid represents a column in DataGrid 1 Contains fields like Name/Header, DataType, Validation Behaviour, Default Value, Data Formatting, etc. Also contains a function to be able to set-up how it should be displayed. The user can select from, for instance, ComboBoxColumn (and also add the available options), DateTime, normal TextBox, CheckBox etc. After finishing adding a row it will automatically appear as a new column in DataGrid 1 I'd appreciate any kind of pointer into the right direction. Thanks very, very much in advance! :)

• NullReferenceException when calling InsertOnSubmit in Linq to Sql.

  - by Charlie

  I'm trying to insert a new object into my database using LINQ to SQL but get a NullReferenceException when I call InsertOnSubmit() in the code snippet below. I'm passing in a derived class called FileUploadAudit, and all properties on the object are set. public void Save(Audit audit) { try { using (ULNDataClassesDataContext dataContext = this.Connection.GetContext()) { if (audit.AuditID > 0) { throw new RepositoryException(RepositoryExceptionCode.EntityAlreadyExists, string.Format("An audit entry with ID {0} already exists and cannot be updated.", audit.AuditID)); } dataContext.Audits.InsertOnSubmit(audit); dataContext.SubmitChanges(); } } catch (Exception ex) { if (ObjectFactory.GetInstance<IExceptionHandler>().HandleException(ex)) { throw; } } } Here's the stack trace: at System.Data.Linq.Table`1.InsertOnSubmit(TEntity entity) at XXXX.XXXX.Repository.AuditRepository.Save(Audit audit) C:\XXXX\AuditRepository.cs:line 25" I've added to the Audit class like this: public partial class Audit { public Audit(string message, ULNComponent component) : this() { this.Message = message; this.DateTimeRecorded = DateTime.Now; this.SetComponent(component); this.ServerName = Environment.MachineName; } public bool IsError { get; set; } public void SetComponent(ULNComponent component) { this.Component = Enum.GetName(typeof(ULNComponent), component); } } And the derived FileUploadAudit looks like this: public class FileUploadAudit : Audit { public FileUploadAudit(string message, ULNComponent component, Guid fileGuid, string originalFilename, string physicalFilename, HttpPostedFileBase postedFile) : base(message, component) { this.FileGuid = fileGuid; this.OriginalFilename = originalFilename; this.PhysicalFileName = physicalFilename; this.PostedFile = postedFile; this.ValidationErrors = new List<string>(); } public Guid FileGuid { get; set; } public string OriginalFilename { get; set; } public string PhysicalFileName { get; set; } public HttpPostedFileBase PostedFile { get; set; } public IList<string> ValidationErrors { get; set; } } Any ideas what the problem is? The closest question I could find to mine is here but my partial Audit class is calling the parameterless constructor in the generated code, and I still get the problem. UPDATE: This problem only occurs when I pass in the derived FileUploadAudit class, the Audit class works fine. The Audit class is generated as a linq to sql class and there are no Properties mapped to database fields in the derived class.

  I've just finished my first ASP.NET MVC (2) CMS. Next step is to build website that will show data from CMS's database. This is website design: #1 (Red box) - displays article categories. ViewModel: public class CategoriesDisplay { public CategoriesDisplay() { } public int CategoryID { set; get; } public string CategoryTitle { set; get; } } #2 (Brown box) - displays last x articles; skips those from green box #3. Viewmodel: public class ArticleDisplay { public ArticleDisplay() { } public int CategoryID { set; get; } public string CategoryTitle { set; get; } public int ArticleID { set; get; } public string ArticleTitle { set; get; } public string URLArticleTitle { set; get; } public DateTime ArticleDate; public string ArticleContent { set; get; } } #3 (green box) - Displays last x articles. Uses the same ViewModel as brown box #2 #4 (blue box) - Displays list of upcoming events. Uses dataContext.Model.Event as ViewModel Boxes #1, #2 and #4 will repeat all over the site and they are part of Master Page. So, my question is: what is the best way to transfer this data from Model to Controller and finally to View pages? Should I make a controller for master page and ViewModel class that will wrap all this classes together OR Should I create partial Views for every of these boxes and make each of them inherit appropriate class (if it is even possible that it works this way?) OR Should I put this repeated code in all controllers and all additional data transfer via ViewData, which would be probably the worse way :) OR There is maybe a better and more simple way but I don't know/see it? Thanks in advance, Ile EDIT: If your answer is #1, then please explain how to make a controller for master page! EDIT 2: In this tutorial is described how to pass data to master page using abstract class: http://www.asp.net/LEARN/mvc/tutorial-13-cs.aspx In "Listing 5 – Controllers\MoviesController.cs", data is retrieved directly from database using LINQ, not from repository. So, I wonder if this is just in this tutorial, or there is some trick here and repository can't/shouldn't be used?

• Dataform fields won't appear

  - by dsetton

  Hello! I am trying to learn how to use the Silverlight 3 DataForm control, because I need to define the DataForm fields myself in the XAML code, that is, I don't want to use the AutoGenerateFields property. My problem is: the dataform works perfectly when the AutoGenerateFields is set to true, but when I create a DataForm and set the fields manually and run the application, all I get is an empty blank rectangle where my form and its fields should be. I created a blank Silverligh Navigation Application to test this, and below is the code of the Home.xaml page: <Grid x:Name="LayoutRoot"> <StackPanel> <!-- This doesn't work. It renders a blank rectangle --> <dataFormToolkit:DataForm x:Name="DataForm"> <dataFormToolkit:DataForm.EditTemplate> <DataTemplate> <StackPanel dataFormToolkit:DataField.IsFieldGroup="True"> <dataFormToolkit:DataField> <TextBox Text="Test1" /> </dataFormToolkit:DataField> <dataFormToolkit:DataField> <TextBox Text="Test2" /> </dataFormToolkit:DataField> <dataFormToolkit:DataField> <TextBox Text="Test3" /> </dataFormToolkit:DataField> </StackPanel> </DataTemplate> </dataFormToolkit:DataForm.EditTemplate> </dataFormToolkit:DataForm> <!-- This works. --> <dataFormToolkit:DataForm x:Name="DataForm2"/> </StackPanel> </Grid> To make the second DataForm work, I simply created a Person class, and put the following in Home.xaml.cs: protected override void OnNavigatedTo(NavigationEventArgs e) { Person client = new Person { Age = 10, DateOfBirth = new DateTime(1980, 10, 20), FirstName = "John", LastName = "Doe" }; DataForm2.CurrentItem = client; } You can see what happens when I run the application in the following link: http://dl.dropbox.com/u/1946004/image.PNG (I don't have enough points to post images, so...) Does anyone know what's wrong? Thank you in advance.

• Problem with FedEx Address validation web service

  - by DJ Matthews

  Hi, I'm trying to get started with Fedex'es Address validation service and I'm running into a road block with FedEx's own demo application. This is the code in there app: Sub Main() ''# Build a AddressValidationRequest object Dim request As AddressValidationRequest = New AddressValidationRequest() Console.WriteLine("--- Setting Credentials ---") request.WebAuthenticationDetail = New WebAuthenticationDetail() request.WebAuthenticationDetail.UserCredential = New WebAuthenticationCredential() request.WebAuthenticationDetail.UserCredential.Key = "###" ''# Replace "XXX" with the Key request.WebAuthenticationDetail.UserCredential.Password = "###" ''# Replace "XXX" with the Password Console.WriteLine("--- Setting Account Information ---") request.ClientDetail = New ClientDetail() request.ClientDetail.AccountNumber = "###" ''# Replace "XXX" with clients account number request.ClientDetail.MeterNumber = "###" ''# Replace "XXX" with clients meter number request.TransactionDetail = New TransactionDetail() request.TransactionDetail.CustomerTransactionId = "Address Validation v2 Request using VB.NET Sample Code" ''# This is just an echo back request.Version = New VersionId() request.RequestTimestamp = DateTime.Now Console.WriteLine("--- Setting Validation Options ---") request.Options = New AddressValidationOptions() request.Options.CheckResidentialStatus = True request.Options.MaximumNumberOfMatches = 5 request.Options.StreetAccuracy = AddressValidationAccuracyType.LOOSE request.Options.DirectionalAccuracy = AddressValidationAccuracyType.LOOSE request.Options.CompanyNameAccuracy = AddressValidationAccuracyType.LOOSE request.Options.ConvertToUpperCase = True request.Options.RecognizeAlternateCityNames = True request.Options.ReturnParsedElements = True Console.WriteLine("--- Address 1 ---") request.AddressesToValidate = New AddressToValidate(1) {New AddressToValidate(), New AddressToValidate()} request.AddressesToValidate(0).AddressId = "WTC" request.AddressesToValidate(0).Address = New Address() request.AddressesToValidate(0).Address.StreetLines = New String(0) {"10 FedEx Parkway"} request.AddressesToValidate(0).Address.PostalCode = "38017" request.AddressesToValidate(0).CompanyName = "FedEx Services" Console.WriteLine("--- Address 2 ---") request.AddressesToValidate(1).AddressId = "Kinkos" request.AddressesToValidate(1).Address = New Address() request.AddressesToValidate(1).Address.StreetLines = New String(0) {"50 N Front St"} request.AddressesToValidate(1).Address.PostalCode = "38103" request.AddressesToValidate(1).CompanyName = "FedEx Kinkos" Dim addressValidationService As AddressValidationService.AddressValidationService = New AddressValidationService.AddressValidationService ''# Try ''# This is the call to the web service passing in a AddressValidationRequest and returning a AddressValidationReply Console.WriteLine("--- Sending Request..... ---") Dim reply As New AddressValidationReply() reply = addressValidationService.addressValidation(request) Console.WriteLine("--- Processing request.... ---") ''#This is where I get the error If (Not reply.HighestSeverity = NotificationSeverityType.ERROR) And (Not reply.HighestSeverity = NotificationSeverityType.FAILURE) Then If (Not reply.AddressResults Is Nothing) Then For Each result As AddressValidationResult In reply.AddressResults Console.WriteLine("Address Id - " + result.AddressId) Console.WriteLine("--- Proposed Details ---") If (Not result.ProposedAddressDetails Is Nothing) Then For Each detail As ProposedAddressDetail In result.ProposedAddressDetails Console.WriteLine("Score - " + detail.Score) Console.WriteLine("Address - " + detail.Address.StreetLines(0)) Console.WriteLine(" " + detail.Address.StateOrProvinceCode + " " + detail.Address.PostalCode + " " + detail.Address.CountryCode) Console.WriteLine("Changes -") For Each change As AddressValidationChangeType In detail.Changes Console.WriteLine(change.ToString()) Next Console.WriteLine("") Next End If Console.WriteLine("") Next End If Else For Each notification As Notification In reply.Notifications Console.WriteLine(notification.Message) Next End If Catch e As SoapException Console.WriteLine(e.Detail.InnerText) Catch e As Exception Console.WriteLine(e.Message) End Try Console.WriteLine("Press any key to quit !") Console.ReadKey() End Sub It seems to send the request object to the web service, but the"reply" object is returned with "Nothing". I could understand if I wrote the code, but good god... they can't even get their own code to work? Has anyone else seen/fixed this problem?

• [AS3/C#] Byte encryption ( DES-CBC zero pad )

  - by mark_dj

  Hi there, Currently writing my own AMF TcpSocketServer. Everything works good so far i can send and recieve objects and i use some serialization/deserialization code. Now i started working on the encryption code and i am not so familiar with this stuff. I work with bytes , is DES-CBC a good way to encrypt this stuff? Or are there other more performant/secure ways to send my data? Note that performance is a must :). When i call: ReadAmf3Object with the decrypter specified i get an: InvalidOperationException thrown by my ReadAmf3Object function when i read out the first byte the Amf3TypeCode isn't specified ( they range from 0 to 16 i believe (Bool, String, Int, DateTime, etc) ). I got Typecodes varying from 97 to 254? Anyone knows whats going wrong? I think it has something to do with the encryption part. Since the deserializer works fine w/o the encryption. I am using the right padding/mode/key? I used: http://code.google.com/p/as3crypto/ as as3 encryption/decryption library. And i wrote an Async tcp server with some abuse of the threadpool ;) Anyway here some code: C# crypter initalization code System.Security.Cryptography.DESCryptoServiceProvider crypter = new DESCryptoServiceProvider(); crypter.Padding = PaddingMode.Zeros; crypter.Mode = CipherMode.CBC; crypter.Key = Encoding.ASCII.GetBytes("TESTTEST"); AS3 private static var _KEY:ByteArray = Hex.toArray(Hex.fromString("TESTTEST")); private static var _TYPE:String = "des-cbc"; public static function encrypt(array:ByteArray):ByteArray { var pad:IPad = new NullPad; var mode:ICipher = Crypto.getCipher(_TYPE, _KEY, pad); pad.setBlockSize(mode.getBlockSize()); mode.encrypt(array); return array; } public static function decrypt(array:ByteArray):ByteArray { var pad:IPad = new NullPad; var mode:ICipher = Crypto.getCipher(_TYPE, _KEY, pad); pad.setBlockSize(mode.getBlockSize()); mode.decrypt(array); return array; } C# read/unserialize/decrypt code public override object Read(int length) { object d; using (MemoryStream stream = new MemoryStream()) { stream.Write(this._readBuffer, 0, length); stream.Position = 0; if (this.Decrypter != null) { using (CryptoStream c = new CryptoStream(stream, this.Decrypter, CryptoStreamMode.Read)) using (AmfReader reader = new AmfReader(c)) { d = reader.ReadAmf3Object(); } } else { using (AmfReader reader = new AmfReader(stream)) { d = reader.ReadAmf3Object(); } } } return d; }

• Failed to load viewstate

  - by Jen

  OK have just started getting this error and I'm not sure why. I have a hosting page which has listview and a panel with a usercontrol. The listview loads up records with a linkbutton. You click the link button to edit that particular record - which gets loaded up in the formview (within the usercontrol) which goes to edit mode. After an update occurs in the formview I'm triggering an event which my hosting page is listening for. The hosting page then rebinds the listview to show the updated data. So this all works - but when I then go to click on a different linkbutton I get the below error: Webpage error details User Agent: Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1; WOW64; Trident/4.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; Media Center PC 6.0; InfoPath.3) Timestamp: Fri, 18 Jun 2010 03:15:54 UTC Message: Sys.WebForms.PageRequestManagerServerErrorException: Failed to load viewstate. The control tree into which viewstate is being loaded must match the control tree that was used to save viewstate during the previous request. For example, when adding controls dynamically, the controls added during a post-back must match the type and position of the controls added during the initial request. Line: 4723 Char: 21 Code: 0 URI: http://localhost:1951/AdminWebSite/ScriptResource.axd?d=yfdLw4zYs0bqYqs1arL-htap1ceeKCyW1EXhrhMZy_AqJ36FUpx8b2pzMKL6V7ebYsgJDVm_sZ_ykV1hNtFqgYcJCLLtardHm9-yyA7zC4k1&t=ffffffffec2d9970 Any suggestions as to what is actually wrong?? My event listener does this: protected void RatesEditDate1_EditDateRateUpdated() { if (IsDateRangeValid(txtDisplayFrom, txtDisplayTo)) { PropertyAccommodationRates1.DataBind(); } else { pnlViewAccommodationRates.Visible = false; } divEditRate.Visible = false; } When I click my link button - it should be hitting this but the second time round it errors before hitting the breakpoint: protected void RatesEditDate1_EditDateRateSelected(DateTime theDateTime) { // make sure everything else is invisible pnlAddAccommodation.Visible = false; pnlViewEditAccommodations.Visible = false; RatesEditDate1.TheDateTime = theDateTime; RatesEditDate1.PropertyID = (int)Master.PropertyId; if (!String.IsNullOrEmpty(Accommodations1.SelectedValue)) { RatesEditDate1.AccommodationTypeID = Convert.ToInt32(Accommodations1.SelectedValue); } else { RatesEditDate1.AccommodationTypeID = 0; } divEditRate.Visible = true; } So my listview appears to be being rebound successfully - I can see my changed data.. I just don't know why its complaining about viewstate when I click on the linkbutton. Or is there a better way to update the data in my listview? My listview and formview are bound to objectdata sources (in case that matters) Thanks for the help!

• How do you Send More that 20 Parameters to a Stored Procedure Using ODP.Net?

  - by discwiz

  Switching from Microsofts Oracle Driver to ODP.NET version 10.2.0.100. After changing the data types to OracleDBTypes in a procedure, that worked perficetly using System.Data.OracleClient, the procedure fails if we try and pass in more that 20 parameters.

• Handling Errors from HttpWebRequest.GetResponse

  - by Jason

  Hey experts - I'm having a ridiculous time trying to get an SMS API working (ZeepMobile, if you're interested) with .NET... I've been around .NET for a few years, but with all this social networking and API stuff, I need to get into the HttpWebRequest a bit. I'm new at it, but not completely new; I was able to hook up my site to Twitter without too much fuss (ie, I was able to modify someone's code to work for me). Anyways, the way their API works is to send an SMS message, you send them a POST and they respond back to you. I can send it just fine, but every time I do, rather than echo back something helpful to figure out what the error is, I get the Yellow Error Page Of Death (YEPOD) saying something to the effect of "The remote server returned an error: (400) Bad Request." This occurs on my line: '...creation of httpwebrequest here...' Dim myWebResponse As WebResponse myWebResponse = request.GetResponse() '<--- error line Is there any way to simply receive the error from the server rather than have the webserver throw an exception and give me the YEPOD? Or better yet, can anyone post a working example of their Zeep code? :) Thanks! EDIT: Here's my whole code block: Public Shared Function SendTextMessage(ByVal username As String, _ ByVal txt As String) As String Dim content As String = "user_id=" + _ username + "&body=" + Current.Server.UrlEncode(txt) Dim httpDate As String = DateTime.Now.ToString("r") Dim canonicalString As String = API_KEY & httpDate & content Dim encoding As New System.Text.UTF8Encoding Dim hmacSha As New HMACSHA1(encoding.GetBytes(SECRET_ACCESS_KEY)) Dim hash() As Byte = hmacSha.ComputeHash(encoding.GetBytes(canonicalString)) Dim b64 As String = Convert.ToBase64String(hash) 'connect with zeep' Dim request As HttpWebRequest = CType(WebRequest.Create(_ "https://api.zeepmobile.com/messaging/2008-07-14/send_message"), HttpWebRequest) request.Method = "POST" request.ServicePoint.Expect100Continue = False ' set the authorization levels' request.Headers.Add("Authorization", "Zeep " & API_KEY & ":" & b64) request.ContentType = "application/x-www-form-urlencoded" request.ContentLength = content.Length ' set up and write to stream' Dim reqStream As New StreamWriter(request.GetRequestStream()) reqStream.Write(content) reqStream.Close() Dim msg As String = "" msg = reqStream.ToString Dim myWebResponse As WebResponse Dim myResponseStream As Stream Dim myStreamReader As StreamReader myWebResponse = request.GetResponse() myResponseStream = myWebResponse.GetResponseStream() myStreamReader = New StreamReader(myResponseStream) msg = myStreamReader.ReadToEnd() myStreamReader.Close() myResponseStream.Close() ' Close the WebResponse' myWebResponse.Close() Return msg End Function
