We have an application that needs the 3.5 SP1 framework and when we click on the prerequisite option in the setup kit we made, we only see the framework without the SP1. When we install, it does not indeed install the correct one. Is there a way to make this work? The application was made in WPF if that changes anything. Thanks! ...
I am currently using sequential workflows in Windows WF, but need to break up the process because I now have multiple workflows that need to share a piece of functionality. I believe there's a way to create custom code activities in WF that would basically accomplish this, but my plan is to eventually ditch WF in favor of Stateless; the...

Consider this: Dim StartDate As DateTime = #06/12/2010 6:32PM# Dim EndDate As DateTime = #06/13/2010 10:47PM# Dim ElapsedSpan As TimeSpan = StartDate - EndDate Does the TimeSpan object retain the original Start and End datetimes that make up the span period? It doesn't appear to and only seems to store the amount of time elapsed not t...
In a new class I'm writing, I need to take the contents of an external XML data feed and convert it into an HTML table via C# and .NET 2.0 (cannot go any higher due to server constraints). Since we reuse the code, I'm putting this functionality into a class. Here is the XML Loader class: using System; using System.Web; using System.Data...
Unfortunately we used intellilock to licence our software. A licence file works in everywhere but not in one of our clients. It's a really stupid situation because we have no inner knowledge or way to debug the licencing component: Intellilock doesn't answer support emails, they don't have a phone number either Intellilock exceptions ...
I have a DataGridView bound to a DataTable in a DataSet. I set all columns of the DataTable to System.Double.

In all the books I've read on reflection they often say that there aren't many cases where you want to generate IL on the fly, but they don't give any examples of where it does make sense. After seeing Reflection.Emit as a job requirement for a gaming company I was curious where else it's being used. I'm now wondering if there are an...
Say I have a basic interface like the following: public interface IObjectProvider { IEnumerable<IObject> GetObjects(); } The object source is some backing store that might be updated, and the implementation of this interface takes care of using that backing store. Now I'd like consumers of this interface to be able to take actions...

Is it possible to use a primitive-typed Collection, such as List<long>, as the DataSource for a DataGridView? After a half-hearted attempt to make it work, I gave in and created a simple struct so I could give DataGridViewColumn a PropertyName. But now I have to box my values when I deal with the UI, unbox them for the rest of my app (...

SqlConnection con = new SqlConnection("connection string here"); SqlDataAdapter da = new SqlDataAdapter(); SqlCommand cmd = new SqlCommand("getDates", con); SqlParame...
I'm going through some old C#.NET code in an ASP.NET application making sure that all SqlConnections are wrapped in using blocks. This piece of code used to open cn and da and close and dispose them in both the catch block and the end of the method. I added the usings and can't figure out for certain if the using blocks still handle dis...

I'm going through some old C#.NET code in an ASP.NET application making sure that all SqlConnections are wrapped in using blocks. I know that using is the same as try / finally where it disposes of the object in the finally no matter what happens in the try.
