I'm the only one in the company using Windows 7 which we are evaluating to decide if/when we're going to upgrade all our PC's. I am a domain administrator and my PC is in the domain and I'm authenticated. Since I installed Win 7 I haven't had any other authentication issues. The apps are built on .NET 2.0 SP2 I don't know much about our domain setup which is handled by our network administrator but I'm told that the Primary Controller is a Windows 2003 and the Secondary is Windows 2000. He tells me that by default every workstation first authenticate on the Secondary controller if it's available.
Here's the StackTrace

I can't send email via ASP.NET and sent an email to my web hosts for some help and was told to modify my security settings and was sent a link:[URL]..I've read what it said there and tried setting <trust level="Full" originUrl="" /> in web.config, but then I get the error:
This configuration section cannot be used at this path. This happens when the site administrator has locked access to this section using <location allowOverride="false"> from an inherited configuration file.
I've not set any other web.config file.So I asked the web hosts again, and asked if it was a server setting which I cannot change, but the response I got was just:
You'll need to specify a more specific path. Which is lovely, but I've no idea what that means! Having done a bit more digging I am wondering if I have to set up a separate trust file, is this correct? Could someone point me in the direction of the correct way to set up my Trust level (I realise "full" is probably incorrect as well?) as I really don't understand what I am supposed to do!
I am having a devil of a time getting a couple of VB 2003 web apps that have been converted to VB 2005 to run on the remote server I use ... I am able to debug/run them on my local development machine. The problem seems to be centered around the web.config files for these apps. They each contain <compilation> elements with embedded <compilers> and <compiler ...> child elements. The <compiler ...> element has a number of attributes including compilerOptions. When I run each app from the server I get the following message:

Is it possible to read the GUID from the Assembly without actually loading it in the current App Domain.
Normally Assembly.Load loads the DLL into the app domain. I just want to read the value. The description of the GUID is
'The following GUID is for the ID of the typelib
' if this project is exposed to COM
<Assembly: Guid("DEDDE61CD-928E-4ACD-8C25-3B8577284819")>
The main thing is I don't want to lock the file so that there are no errors 'Another process is accessing the file' error.
I am creating what could amount to quite a few temp files on a terminal server using the System.IO.Path.GetTempPath. My question is this. Can I trust Windows to clear that directory on a regular basis or do I need to clear it in code?
View 4 RepliesI am architecting a program that I need some help on. I need to have a "watcher" program that will sit on a server and monitor a SQL Server. At configured intervals, the watcher will run a query on the server and create a dataset of information I want to share to any clients that are listening. I am looking at WCF Peer channel but all I can see is peer to peer chat and most of the examples I have seen are partial examples. I have looked at the example program from Microsoft but I am still a bit confused. The listener programs will receive the dataset of values from the watcher and filter the data at the local level and display the data they need and display it to the end user. I don't know if a TCP client/server would be a better solution, but the dataset may contain up to 10,000 rows of data. From what I read the WCF Peer channel will transmit at 50 mbps and should handle this load. My other option is a server/client architecture using TCP spawning a new thread for each request. Does anyone have any good examples, or articles about WCF and VB that they can point me to?
View 2 RepliesI've got a micro controller with 4 channel ADC that I want to make a program for. It will be for data logging. I want to take each channel and display it in 4 textboxes to begin with.Later I like to do some conversions of the data to show temperature , use a lookup table and a few other things in each of these boxes, but at first I'd just like to concentrate on getting the data split into each box.The chip output is 8 bytes . The first two are the channel select and the next two is the data. Output of the chip is in ASCII. I don't want to send to the chip, just receive.If I view the output in decimal I get 1xx 2xx 3xx 4xx (xx being the data to display).

I am developing a COM Add-in using VB.NET in Visual Studio 2008 Pro for Outlook 2003 and am having trouble assigning images to custom toolbar buttons. In a nutshell, I am having to convert from an Icon type to a stdole.IPictureDisp type so that I can assign my buttons a picture. The picture displays, but it loses the Alpha channel and the background is no longer transparent. I can verify that before the conversion to IPictureDisp object, that the PixelFormat property is set to Format32bppArgb (2498570). I am using a coding technique suggested here:[URL]. For C# users, this link [URL] shows how to modify the IPictureDisp one pixel at a time and rebuild the transparency, but I can't find similar functions in VB.NET...

View 1 RepliesI'm designing a web service in ASP.NET and VS2008, and am using typed datasets for retrieving table data. These work well and establish their own connections through their associated TableAdapter objects. Edit: I'm using VB, BTW!I am now attempting to run a custom SQL string using a DataAdapter and a Command object, however I need to reference a Connection object in order for the Command to work. What is the best way to handle this?hould I:a) Create a global connection object using Global.asax, retrieving the connection string from web.config? (I've been trying that one already, with not much success)b) Create a class-level connection object using the InitialiseComponent method, also retrieving the ConnectionString from web.config?c) Retrieve a Connection from one of the TableAdapters that I've already created in my typed DataSets?d) Something else I haven't thought of yet?
