• .NET Development Failed to access IIS metabase, VS2005 RC

  I am developing a webservice in Visual Studio RC. I have just got a new pc and my problem is that I am not able to access this webservice.

• Visual Basic Threading not working as expected (using a COM class in a BackgroundWorker)

  Hi, I've written a COM server class (KCAMSERVERLib.Camera) to remotelly control digital cameras from the computer through a USB cable. I'm now in the process of writing a simple GUI for it, and I've chosen VB2005 for that purpose. Some actions, like "Shoot()"ing a picture, take some time so I added a BackgroundWorker object to my VB project to run them in a separate thread. The problem is that the GUI still freezes during shooting, like it all was run in the same thread. I post here a simple test that shows this behaviour: Public Class Form1 Dim Camera As New KCAMSERVERLib.Camera Private Sub Form1_Load(ByVal sender As Sy ...Show All

• SQL Server Deployment

  Hello, I was reading some article which said, the reporting service (sql server 2005)does not have many capabilities and so, after initial development of reports you can deploy it to a custom website or an application and then use .net to enhance report functionalities...

• Windows Forms Keeping connection open: Good Idea?

  Making the transition from ASP.Net to windows forms.   While I would never do this in ASP.Net, it seems that it may not be a bad idea in windows forms: I have a pretty straightforward little application where I have a main form that remains open as long as the application is running.  Various other forms are opened from this main form an ...Show All

• Visual Studio 2008 (Pre-release) C# 3.0 Feature Suggestion - symbols

  I was playing around with ruby the other day and was reminded of the ":" symbol as in "abc".send(:length), although ruby doesn't care if the :length symbol actually exists on the target, it gave me the idea that we could really use a language feature that would have compile time checking for class members to be used as an alternative to passing around field/property names as strings that are later used in reflection apis, O/R mappers, rule engines, WPF, etc. Reflection can be useful way to remove clutter from the domain model and make the code simpler it can also introduce hard to find bugs (if your tests aren't good enou ...Show All

• .NET Development Graphics in component forms for multi thread applications

  I want to use a component form in a thread to process graphics in the backgroung.  But the component module doesn't recognize the graphics code that a regular form does.

• SQL Server Dynamic Connections

  I have read the posts on dynamic connections and still am not able to get it to work. Sorry, but I need specific instructions. I know it has something to do with the For Each Loop container, and something with the package variable, but I need more instruction. What I am trying to do is transfer data from several (86) servers to a central server (all SQL Servers). The many servers will have the same code run against them to gather data and transfer it to the central server. I have written a package with those two objects for each server, but I know that there has to be a way to create just those two objects with the connection of the first ...Show All

• Windows Forms ClickOnce updates all assemblys!

  Hi, I am now trying to deploy with Click Once, and have run into 2 problems/questions. I have 6 projects 1 win and 5 class libs. I seem to think that with Click Once I should be able to make a change to library X and redeploy, in turn the user would only need to download that one assembly. The problem I am having is, a change to 1 library forces the user to download the entire application again. I must just be missing something, what is the way around this Thanks Are you sure it download the whole app ClickOnce is designed to only download changed files.
