• anothernewVBguy Unique Machine Identifier

  Can anyone suggest a mechanism for gettting a reasonably unique machine identifier. I.e. a value that is reasonably unique on a machine by machine basis. I looked at using a Security Identifier, but these seem only to be unique for a particular system. How about the MAC address of your network card public static void DisplayTypeAndAddress() { IPGlobalProperties computerProperties = IPGlobalProperties.GetIPGlobalProperties(); NetworkInterface[] nics = NetworkInterface.GetAllNetworkInterfaces(); Console.WriteLine("Interface information for {0}.{1} ", computerProperties.HostName, computerProperties.DomainName); foreach (NetworkInterface adapter in nics) { IP ...Show All

• N_John What happened to App.Config files in VS 2005 ?

  I'm not sure where the proper place for this question is, but I have been using Visual Studio 2005 for a little while now, and I noticed that there are no more app.config files. What happened to them What replaces their functionality Is there any good documentation you can point me to on where this went Thanks Brendan Grant wrote: Nay they still exist. To add one to your project right click on the project and choose Add from the menu and then New Item. From the new window that pops up look for the 'Application Configuration File' option, select it and hit Add and you'll have a brand new App.config file added to your project. Hi, Brendan!

• Horst Klein SecureString Usability

  I'm sure this is very obvious, but why doesn't the SecureString class support an "AppendString" or equivalent method I've searched the forums and cannot find an answer I've seen code that simply iterates the characters in a string and appends them as it loops. Is this bad practice If not why isn't the SecureString class more helpful Can anyone help I'm confused... Thanks I don't really want the functionality to add a string multiple times. I'd want a constructor that contains the logic: foreach (Char someChar in someString.ToCharArray()) { ss.AppendChar(someChar); } ss.MakeReadOnly(); To make it easier to use.

• Jason Du Must a Table be added before trying to store data?

  Hi, I'm trying to connect to a SQL Server 2000 database, and add the following info. I got a snippet from codeproject and I don't really know what I'm doing. This is what I've got so far.

• Dvlnblk Using classic ADO parameter objects from VC#2005

  Hi everyone Apologies if this is the incorrect forum for this posting, please let me know if I should repost elsewhere in a more appropriate location. I'm trying to use parameterized queries with classic ADO. I've done this successfully with ADO .NET 2.0, but because of the legacy ODBC drivers that we are needing to support which cause a crash when using ADO .NET I am having to use classic ADO. I'm using the following code to create the parameter and assign to the command object: private object m = System. Type .Missing; adorecordset = new ADODB. Recordset (); ADODB.

• kirchu CAS declarative security

  How come it is not possible for an otherwise fully trusted assembly to refuse some permissions (declaratively) without loosing it's full trust status Hello All. Mikkel: As to your first question, there very well could be, but I don't know about it. Sorry. As to your second, I'm still a little fuzzy on this part, but if I'm not mistaken, since System.Web.dll requres fully-trusted code by way of a link demand, this results in a stack walk back to your code, which has restricted permissions, and so throws the exception. That's one of the primary considerations I'm still trying to figure out, in that such emphasis is placed on writing code that will function under partial-trust, but a large chunk of the .NET class library will ...Show All
