  • ASP.Net Session_Start event not firing

    - by Jazza
    I have an ASP.Net 2.0 application in which the Session_Start event is not firing in my Global.asax file. Can anyone tell why this is happening and how I can get it working? The application worked fine on my Windows XP development machine, but stopped working when deployed to the server (Win Server 2003/IIS 6/ASP.Net 2.0). I'm not sure if this is relevant, but the server also hosts a SharePoint installation (WSS 3.0) which I know does change some settings at the default web site level.

  • .NET file Decryption - Bad Data

    - by Jon
    I am in the process of rewriting an old application. The old app stored data in a scoreboard file that was encrypted with the following code: private const String SSecretKey = @"?B?n?Mj?"; public DataTable GetScoreboardFromFile() { FileInfo f = new FileInfo(scoreBoardLocation); if (!f.Exists) { return setupNewScoreBoard(); } DESCryptoServiceProvider DES = new DESCryptoServiceProvider(); //A 64 bit key and IV is required for this provider. //Set secret key For DES algorithm. DES.Key = ASCIIEncoding.ASCII.GetBytes(SSecretKey); //Set initialization vector. DES.IV = ASCIIEncoding.ASCII.GetBytes(SSecretKey); //Create a file stream to read the encrypted file back. FileStream fsread = new FileStream(scoreBoardLocation, FileMode.Open, FileAccess.Read); //Create a DES decryptor from the DES instance. ICryptoTransform desdecrypt = DES.CreateDecryptor(); //Create crypto stream set to read and do a //DES decryption transform on incoming bytes. CryptoStream cryptostreamDecr = new CryptoStream(fsread, desdecrypt, CryptoStreamMode.Read); DataTable dTable = new DataTable("scoreboard"); dTable.ReadXml(new StreamReader(cryptostreamDecr)); cryptostreamDecr.Close(); fsread.Close(); return dTable; } This works fine. I have copied the code into my new app so that I can create a legacy loader and convert the data into the new format. The problem is I get a "Bad Data" error: System.Security.Cryptography.CryptographicException was unhandled Message="Bad Data.\r\n" Source="mscorlib" The error fires at this line: dTable.ReadXml(new StreamReader(cryptostreamDecr)); The encrypted file was created today on the same machine with the old code. I guess that maybe the encryption / decryption process uses the application name / file or something and therefore means I can not open it. Does anyone have an idea as to: A) Be able explain why this isn't working? B) Offer a solution that would allow me to be able to open files that were created with the legacy application and be able to convert them please? Here is the whole class that deals with loading and saving the scoreboard: using System; using System.Collections.Generic; using System.Text; using System.Security.Cryptography; using System.Runtime.InteropServices; using System.IO; using System.Data; using System.Xml; using System.Threading; namespace JawBreaker { [Serializable] class ScoreBoardLoader { private Jawbreaker jawbreaker; private String sSecretKey = @"?B?n?Mj?"; private String scoreBoardFileLocation = ""; private bool keepScoreBoardUpdated = true; private int intTimer = 180000; public ScoreBoardLoader(Jawbreaker jawbreaker, String scoreBoardFileLocation) { this.jawbreaker = jawbreaker; this.scoreBoardFileLocation = scoreBoardFileLocation; } // Call this function to remove the key from memory after use for security [System.Runtime.InteropServices.DllImport("KERNEL32.DLL", EntryPoint = "RtlZeroMemory")] public static extern bool ZeroMemory(IntPtr Destination, int Length); // Function to Generate a 64 bits Key. private string GenerateKey() { // Create an instance of Symetric Algorithm.

  • COM Interop without regasm

    - by SLaks
    I'm a limited user, and I need to write an Outlook macro that exposes a C# library in Outlook 2003 and 2007. I do not have any admin privilges at all, not even at install time, so I can't run RegAsm and I can't (I assume) write a managed add-in. Is there any way to call .Net code from VBA in this scenario, or are there any other solutions? This is for personal use only, so an ugly hack is perfectly acceptable (so long as it works)

  • DevPartner Profiler Community Edition

    - by Henry
    I used to have DevPartner Profiler Community Edition installed on my machine, which was free to use indefinitely and was compatible with Visual Studio 2003. After I have rebuild my machine and downloaded a newer version (version 8.1) of the software, it turns out it is actually a 45 day trial eventhough it is still called a Community Edition. I have tried looking for an older version, but haven't been able to find it. Could someone help me out please?

  • fresh_when in ruby not working with xml rendering

    - by Guilherme Silveira
    While trying to implement support for conditional GETting in a rest system, we have come across the fresh_when and stale? methods. The following code works fine with 304 and not further rendering: if stale?(:etag = resource, :last_modified = resource.updated_at.utc) respond_to do |format| format.html # show.html.erb } end end But accessing 1.xml will try to render the resource twice: if stale?(:etag => resource, :last_modified => resource.updated_at.utc) respond_to do |format| format.html # show.html.erb format.xml { render :xml => @order.to_xml(:controller => self, :except => [:paid_at]) } end end The error message: ActionController::DoubleRenderError in OrdersController#show Can only render or redirect once per action RAILS_ROOT: /Users/guilherme/Documents/ruby/restfulie-test Application Trace | Framework Trace | Full Trace /Library/Ruby/Gems/1.8/gems/actionpack-2.3.4/lib/action_controller/base.rb:900:in render_without_benchmark' /Library/Ruby/Gems/1.8/gems/actionpack-2.3.4/lib/action_controller/benchmarking.rb:51:in render' /Library/Ruby/Gems/1.8/gems/activesupport-2.3.4/lib/active_support/core_ext/benchmark.rb:17:in ms' /Library/Ruby/Gems/1.8/gems/activesupport-2.3.4/lib/active_support/core_ext/benchmark.rb:10:in realtime' /Library/Ruby/Gems/1.8/gems/activesupport-2.3.4/lib/active_support/core_ext/benchmark.rb:17:in ms' /Library/Ruby/Gems/1.8/gems/actionpack-2.3.4/lib/action_controller/benchmarking.rb:51:in render' /Library/Ruby/Gems/1.8/gems/actionpack-2.3.4/lib/action_controller/base.rb:1331:in send' /Library/Ruby/Gems/1.8/gems/actionpack-2.3.4/lib/action_controller/base.rb:1331:in perform_action_without_filters' /Library/Ruby/Gems/1.8/gems/actionpack-2.3.4/lib/action_controller/filters.rb:617:in call_filters' /Library/Ruby/Gems/1.8/gems/actionpack-2.3.4/lib/action_controller/filters.rb:610:in perform_action_without_benchmark' /Library/Ruby/Gems/1.8/gems/actionpack-2.3.4/lib/action_controller/benchmarking.rb:68:in perform_action_without_rescue' /Library/Ruby/Gems/1.8/gems/activesupport-2.3.4/lib/active_support/core_ext/benchmark.rb:17:in ms' /Library/Ruby/Gems/1.8/gems/activesupport-2.3.4/lib/active_support/core_ext/benchmark.rb:10:in realtime' /Library/Ruby/Gems/1.8/gems/activesupport-2.3.4/lib/active_support/core_ext/benchmark.rb:17:in ms' /Library/Ruby/Gems/1.8/gems/actionpack-2.3.4/lib/action_controller/benchmarking.rb:68:in perform_action_without_rescue' /Library/Ruby/Gems/1.8/gems/actionpack-2.3.4/lib/action_controller/rescue.rb:160:in perform_action_without_flash' /Library/Ruby/Gems/1.8/gems/actionpack-2.3.4/lib/action_controller/flash.rb:146:in perform_action' /Library/Ruby/Gems/1.8/gems/actionpack-2.3.4/lib/action_controller/base.rb:532:in send' /Library/Ruby/Gems/1.8/gems/actionpack-2.3.4/lib/action_controller/base.rb:532:in process_without_filters' /Library/Ruby/Gems/1.8/gems/actionpack-2.3.4/lib/action_controller/filters.rb:606:in process' /Library/Ruby/Gems/1.8/gems/actionpack-2.3.4/lib/action_controller/base.rb:391:in process' /Library/Ruby/Gems/1.8/gems/actionpack-2.3.4/lib/action_controller/base.rb:386:in call' /Library/Ruby/Gems/1.8/gems/actionpack-2.3.4/lib/action_controller/routing/route_set.rb:437:in `call' Any suggestions?

  • AccessViolationException thrown

    - by user255371
    Hi, I’m working on a project that’s written in C# and uses a C++ dll to communicate with a robot. Originally the software was written in C# VS 2003 and was converted to VS 2008 (no change to the code) using .Net 2.0. Now, I started seeing the “Attempted to read or write protected memory…” on some computers. The Access violation error is always thrown when the code calls a particular method from the dll, however, that very same method is called over and over throughout the task and executes fine, just sometimes it throws the error. Also, the robot seems to execute the command fine which tells me that the values passed into the dll exist and thus are accessible. The software with the .Net 1.1 has been used for years and worked fine without ever throwing any memory errors. Now that it has been using .Net 2.0 it throws errors on some computers only. I’m not sure what’s causing the issue. I ruled out inappropriate calling (incorrect marshalling …) of the dll methods as it has been working fine with .Net 1.1 for years and thus should work fine in .Net 2.0 as well. I’ve seen some posts suggesting that it could be the GC, but then again why would it only happen on this one computer and only sometimes. Also, the values passed in are all global variables in the C# code and thus they should exist until the application is shut down and GC has no business moving any of those around or deleting them. Another observation, as I mentioned above, the robot executes the command normally which means that it gets all its necessary values. Not sure what the C++ dll’s method would do at the end where the GC could mess up stuff. It shouldn’t try to delete the global variables passed in and the method is not modifying those variables either (I’m not expecting any return values through the passed in values, the only return value is the method return which again shouldn’t have anything to do with GC.) One important piece of information I should add is that I have no access to the C++ code and thus cannot make any changes there. The fix has to come through the C# code or some settings on the computer or something else that I am in control of. Any help greatly appreciated. Thanks. Code snippet: Original method call in VS 2003 [DllImport("TOOLB32.dll",EntryPoint="TbxMoveWash")] public static extern int TbxMoveWash(int tArmId, string lpszCarrierRackId, int eZSelect, int[] lpTipSet, int tVol, bool bFastW); which I modified after seeing the error to the following (but the error still occurs): [DllImport("TOOLB32.dll",EntryPoint="TbxMoveWash")] public static extern int TbxMoveWash(int tArmId, string lpszCarrierRackId, int eZSelect, [MarshalAs(UnmanagedType.LPArray, SizeConst = 8)] int[] lpTipSet, int tVol, bool bFastW);

    I want to know if PHPExcel can: Create Excel spreadsheets with embeded image. The image must be compressed (jpeg, png, gif...). Create Excel spreadsheets for different Excel versions (2000, 2003, 2007...). I'm pretty sure it can do this but I can't find it in the official docs. Anyone familiar with this class can help? Thanks!
