I've created managed code to programmatically provision websites on Windows 2008 servers from a Vista 64-bit workstation.The provisioning covers creating DNS entries, creating a file structure and a the IIS7 site (using Microsoft.Web.Administration aka MWA).I've had to do some DCOM configuration to get it to work through a firewall and it all works on the test server provided I'm in the same domain.I then cloned the Windows Server 2008 Virtual Machine (VM) that the provisioning does work on and then changed the clone's domain to the child domain in the forest where the production servers are sitting.The provisioning user credentials are synchronised on the parent and child domains.So the only change is moving domains and there is an automatically configured trust relationship between the domains.
Provisioning the file system still works on the server on the child domain, but managing DNS and IIS7 now have access issues.I've tried impersonating the Administrator on the child domain (and the thread identity is showing that works) and also had a go with CoInitializeSecurity (though I'm not sure that is appropriate for Win2008 and Vista)to no avail.What I really want to avoid is the need to have to store credentials separately on the workstation - it brings an unwelcome maintenance overhead and the possibility that if the provisioning user's password is changed, then the provisioning will unexpectedly fail on the production servers.Ideally once the provisioning user has logged onto the Vista Workstation, I'd like their credentials to pass through to the servers on the child domains (there are separate DNS and web servers) allowing them to manipulate whatever services (DNS, IIS7, file system) that are necessary.The solutions would seem to be something programmatic (whatever replaced CoInitializeSecurity?) or a Group Policy setting on the child domain may need altering to allow access.However being a humble software developer working out which of the myriad settings (one of the User Rights Assignments perhaps?) is outside my sphere of knowledge.The third alternative is to use Windows Communication Foundation (WCF) but I haven't done much with this yet and what I have indicates that this technology has its own security issues to accommodate.
OK - for starters - I'm not even sure that the title of this thread accurately describes what I want to do - but I had trouble verbalizing it. So I will give this a try: In my application, I have a custom object, call it myObject. In addition, I have another custom object called myObjectList which is basically a List(Of myObject).
Up until this point, all of the functions that I have been working with in my BLL and DAL have been shared - I haven't needed a specific instance of my object thus far. I currently need to write a function that finds a particular myObject within myObjectList and returns to me myObject. I know that the List(Of T) has a find method, but from what I have read so far - I don't think it is what I want (doesn't it return true or false? -and also, do I need an existing object to pass to it to see if it is in the list?)

I need to migrate from Excel 2003 VBA to Excel 2007 VBA. When Microsoft introduced Excel 2007 it removed many objects from the previous versions and added some new objects. Also it hid some properties of particular objects. These hidden properties can be viewed by going to the object browser, right clicking any object and selecting "Show Hidden Members". My problem is I need to access these hidden properties. Is there any way I can access these properties. I can successfully migrate from Excel 2003 VBa to Excel 2007 VBA with the same functionality?
View 5 RepliesI've got a website and we just had a huge jump in traffic. Now all of the sudden we're getting sql parameter errors left and right. We switched to a new sql server a few weeks ago and everything has been fine but the added traffic seems to be breaking us.I have a data access class that is called when each user trys to logon. It runs through several tasks before finally updating the users last login date and forwarding them to the administration section.
What I'm seeing from the trace logs suggests that when I'm logging in the first several tasks are using my data (lets say user=birk pass=word). But at some point the accessor class starts sending over the data from someone else who's trying to login (lets say user=abcxyz).Every connection we make to the server is closed when we're finished with it. I'm nulling out all of the accessor objects when I'm finished with them. But somehow different user data from different sessions are making their way into other peoples instances of the object.
I'm not using session/application/cache/viewstate to store the objects so I'm not really seeing how they could edit eachother... Its just really weird and I'm not sure how to even go about researching the problem.This is roughly the accessor class... I trimmed out some of the parts that weren't reliant to the issue

View 5 RepliesI created a .net assembly, which works perfectly if I create before runtime. But i'd like to know if it's possible to reference at runtime. The reason is because i'm creating an application which will be used in several servers, and it will be reference that same .net assembly, but the .dll file will be in different location per server. I know that when I reference before runtime, the .net assembly it will be pointing to is from the original (or at least that's what I think).
