• Visual C# Same KEY & IV for TripleDES Encryption as well as Decryption in 2 different Win Services.

  Hi, I want to encrypt as well as decrypt a file using TripleDES. My problem is that I am autogenerating the KEY & IV while encrypting the files.

• .NET Development How do you Un-Set a bit field (flag enumeration)...?

For the second question, try setting the KeepTogether property on the List. ...Show All

• .NET Development TypeConverter bug?

  Hello forum. Can somebody explain me, why following code cause an error : decimal d1 = 1000.55M; string s1 = d1.ToString( "N" ); TypeConverter cv = TypeDescriptor .GetConverter( typeof ( Decimal )); object obj = cv.ConvertFrom(s1); While the next code not: decimal d1 = 1000.55M; string s1 = d1.ToString( "N" ); decimal .TryParse(s1, out d1); Through reflector I found, that TypeDescriptor calls internally following: internal override object FromString(string value, NumberFormatInfo formatInfo) { return decimal.Parse(value, NumberStyles.Float, formatInfo); } while Decimal.TryParse calls: public static bool TryParse(string s, out decimal result) { return Number.TryParseDecimal(s ...Show All

• Visual Studio Team System Adding Workgroup users to TFS

  Hi, I'm installing team foundation server on a clean server build in a workgroup environment.  Its all gone smoothly so far and I've managed to create a new team project.  However when I add a workgroup user to the team project they are able to view the portal page but some of the page section are reporting the following error: The permissions granted to user 'CONWY\gwyn' are insufficient for performing this operation. (rsAccessDenied I've added the workgroup users manually to the server as normal users.  The question is do they need to be assigned to the admin group which I'd rather not do. You'll need to grant permissions in Reporting Services in order to view the reports. Use Show Repo ...Show All

• Visual Studio 2008 (Pre-release) store ServiceSecurityContext.Current info

  This may sound strange but is it possible to save the ServiceSecurityContext.Current info so that I can retrieve it and use it later I have a scenario where the client subscribes itself via a subscription service in the host. The host resides in another machine. Later, another service from the same host tries to invoke a method from the subscriber's service. The trouble I'm having is with SSPI negotiation. When I try to invoke the client's method, I get a "SSPI negotiation failed" error. I think if I can tell the Host the client's ServiceSecurityContext.Current info, I won't be running into this problem. Thanks. I'm not sure how to find out the identities but to the best of my know ...Show All

• SQL Server How do I obtain the log file for a DTSX?

• Software Development for Windows Vista IE7 example: Keyset does not exist error

  Hi, Just trying to run the IE7 - cardspace demos on WinXP-SP2. I am able to get the security token from my personal card but during decryption of the token to get the claims, it gives an error: keyset does not exist . I have tried reinstalling the certificates but it did not help. Guys, please help me through this. Regards, Nishant It's important that I should note that you want to be extremely careful modifying the ACLs on keys. Changing the ACL on the directory is very dangerous. By doing that, you've exposed all the private keys. You should restrict the ACL changes to just the private key file for the cert you are using, and only add read permissions to the single account tha ...Show All

• Visual C# Decompress a list of files

  for my program I am trying to take a list of files in the format *.zip and decompress them. I am able to read the list from the folder and initialize decompression with GZip, but then it tells me that the magic number in the header was incorrect and that it cannot decompress it. These files come from other companies and I have no controll over how they are compressed. If GZip can only decompress its own files, what good is it Is there a way to get around this Thanks in advance, Hi, Try using SharpZipLib: http://www.icsharpcode.net/OpenSource/SharpZipLib/ Charles ...Show All

• Software Development for Windows Vista Best Practices: Deploying new workflow instance

  Are there any best practices for deploying new / modified workflows For example, assume that I create a state machine workflow, with version number 1.0.0.0, and I deploy it. Then my application comes along and creates instances of this workflow, and not all instances are complete. Then at some point later, I add a new activity to my workflow and make the version of the containing assembly = 1.0.1.0 and recompile the workflow assembly. How do I deploy this new version of the workflow and what happens to the still running workflows that were created under v 1.0.0.0 of the workflow assembly. When you deply version 1.0.1.0 nothing will happen to the version 1.0.0.0 workflows that are running. They wil ...Show All

  Don't ask why I am trying to do this but I need to migrate a few MySites from a BTR installation to a different BTR installation so I then can upgrade them to RTM.
