I don't think that this is specific to a language or framework, but I am using xUnit.net and C#. I have a function that returns a random date in a certain range. I pass in a date, and the returning date is always in range of 1 to 40 years before the given date. Now I just wonder if there is a good way to unit test this. The best approa...
I have two tables in a DataSet in .NET. I want to join them on an ID column. Then I want a DataGridView to display two columns from the first table and one column from the second table. If it makes it easier, the relation between the two tables is one-to-one. Can it be done? ...
I am not sure if I am missing something grotesquely obvious or what, but I can't seem to figure out how to efficiently access tables in a relational database. I am using PostgreSQL for the database server (and Npgsql for its access) and C# with Mono 2.0. Say I have the table created by the following CREATE TABLE and INSERT statements. ...
I'm writing a simple IDictionary abstraction in C# that wraps a Dictionary<K, ICollection<V>>. Basically, it maps multiple values to one key. I can't decide whether to remove a key and its empty list when the last item in a values list is removed, or leave it (to avoid instantiating a new collection if the key is reused) and do checks ...
In an ongoing effort to improve my code I am looking for the best way to create and compare a salted password in .NET. Is there a better, or more secure, way of doing this? My current code is as follows: public static string CreateSaltedPassword(string salt, string password) { SHA1CryptoServiceProvider SHA1 = null; ...
I'm using Windows Forms and VS2008. I want to store an enum value in my application's settings file. The settings editor in VS2008 only gives me a limited set of types. Amazingly, enums don't seem to be one of these types that are automatically supported - have I understood this correctly? From reading up on the subject, it seems lik...
After attending a talk on Oslo/M I am struggling a bit to see the advantages of using it over existing methods and in what situation it would be useful. I know its quite new and not all details have been released etc but can some one give me some advantages and when you might use it? Thanks, Alex ...
I would like to know what are the best options for a COBOL programmer to switch to more modern platforms. I explored Java but will all its frameworks its overwhelming. .NET appeared much simpler but I'm worried if it will result in a vendor lock-in; we have had enough of it with COBOL. What about other choices such as LAMP, Ruby On rai...
I am writing an application using the Microsoft enterprise library. I wrote a wrapper dll for that enterprise library dll. I want to use my wrapper in some windows form application. The problem is that every time I want to use my wrapper I get an error in the compilation that says that a reference to the enterprise library dll is missing...
I'd like to include custom .Net controls and .Net forms within MS Access. It's possible but I was wondering if there was any new good articles on that subject. Over time I've found a few related to the subject the but always found the process a bit cumbersome (see references below). One of the issue is deployment: my user's machines hav...
I have good experience in working with C++ and know basic Java as well. I want to learn .NET framework in general and C# in particular. How should I go about it? ...
Folks, TIBCO has announced support for WCF channels back in April - has anything of that materialized by now?? Where and how can I download either these new WCF channel bits, or where can I get my hands on a current .NET 2.0/3.5 version of the "TIBCO.EMS .NET client library" ?? We're a small ISV without any ties to TIBCO so far, but ...
I'm trying to accomplish a seemingly super simple thing: from my unit test I want to replace the type being resolved with a mock/fake object. For example: the xml config states that a component of the service IInterface should resolve to ClassA. That's fine, but from my unit test I want the type to resolve to FakeClassA instead. I can't...
I have a .net client application which is connected to a remote database. Is it safe to keep a single connection open for the lifetime of the client (hours)? Does the answer hold if I have multiple (10 or 100) clients running? Thanks ...
What is the best way to abstract the episerver infrastructure for easier testing? ...
...if there is such a thing. Here's an image of two approachs for structuring DLLs/references in a .NET application: http://www.experts-exchange.com/images/t80668/compArch.png. The app can be a website (it is in this case) or a winform. Each box represents a DLL. For the winform app, just replace "webcontrols" with "winformcomponent...
My scenario should be simple... the type I want to convert FROM is ALWAYS 'string'. What I want to convert to... could be many things - ints, DateTimes, ... strings, etc. This would be easy: string valueToConvertFrom = "123"; int blah = Convert.ToInt32(valueToConvertFrom); However... I don't know (until runtime) that the value I nee...
I have a .NET component exposed as a CCW (Com Callable Wrapper) and being loaded into an unmanaged IIS application (ATL server). The assembly is installed and registered with COM using regasm /codebase. The component requires configuration such as is typically put into a Web.config file for an IIS app. But I don't want to drop the con...
I want to pass an integer value to a form in .Net so that it can load the right data. I'm using this so that when I double click on a record in a list, a form opens with the data from that record loaded so it can be edited. What is the best way to do this? Should I create a property and set it before calling the Show() method, or should ...
I am making an app that scrolls information on the desktop. The window is transparent. I am starting out simple, trying to find the lowest CPU use for animating things and I am starting with a simple TextBlock. On my development machine, I get a very smooth animation across the screen setting the Canvas.Left property with a DoubleAnim...
