One of the disadventage I found in WPF is it doesnot have a Numeric UpDown control. So I make a listbox with height as 25 so that it will display only one item at a time and the vertical scroll feels like a UpDown controls. My problem is when I use the scroll to change the value, I can't get the current value shown in listbox. Can any i...
Whenever i try to open my Entity Model, i get a not very helpful error message stating that "the operation could not be completed". So unfortunately i don't have more specific information. However, i have other models that open just fine, and i didn't make any significant changes to the model, other than renaming entities. Are there any...
As the question suggestions, should I be checking the Rectangle to set a Form.Location (which is taken from a Settings file) based on: 1. if (settings.X < Screen.PrimaryScreen.WorkingArea...) { // Set the form's Location based on the settings object } or 2. int width = 0; foreach (Screen screen in Screen.AllScreens) { width ...

I have a class that I want to have opportunities to serialize/deserialize. It implements interface IXMLConvertable: public interface IXMLConvertable<T> where T: new() { T deserialize(XElement element); void serialize(XElement element); } when T is a type of object to deserialize. The question is whether it`s a good practice or...

What is best practice for creating wrapper for WCF service call? I think it is necessary to monitor all calls in the same place, I am thinking to use this kind of code, is this right idea? RetType t = ServiceExecutionContext<IServiceChanel>.Execute(s=>s.GetServiceMethod()); What kind of wrapper are you use in your enterprise applica...
I have a unhandled exception handler (an oxymoron if ever there was one) but I'd like to get more information out of it. At the moment it logs the exception message, stack trace etc. and recursively does the same for any inner exceptions. However often the exception is a derived type of the exception class and therefore I do not know a...
I occasionally use fuslogvw to track down problems loading assemblies. After all my time of using it, it seems that the folder 'NativeImage' has results for loading native images of my dlls. When the native image is not found (usually its not), I think it then looks for a .net assembly. The 'default' folder is what I normally care abo...
Given: a xmlnode that you got from calling the XmlDocument.GetSingleNode method, where you know that the node is an element, if you want to find the simple path to that element, is there something more straightforward than climbing the tree til you get to the root node and buildling the path as you go? Not that that's hard, I just w...
Everyone knows that this is not thread safe: public StringBuilder Builder { get { if (_builder != null) _builder = new StringBuilder(); return _builder; } } What about this? public StringBuilder Builder { get { return _builder ?? (_builder = new StringBuilder()); } } ...
I have a C# console application that logs a lot to the console (using Trace). Some of the stuff it logs is the compressed representation of a network message (so a lot of that is rendered as funky non-alphabetic characters). I'm getting system beeps every so often while the application is running. Is it possible that some "text" I am wr...
I'm working on a .NET 1.1 assembly that does a number of huge XSL transforms. This is beginning to cause memory problems. I therefore want to use the XSLT engine in the .NET 2.0 framework, since I know it is much more efficient and less resource intensive. Note: Upgrading the .NET 1.1 assembly to .NET 2.0 is NOT an option at this time, d...
This may be quite simple but I'm rather new to Lambda's so bear with me. I have a function that uses a Lambda function to recurse. The main function receives a bool telling it to include certain information or not within the lambda. The function is designed to write out a custom class to XML - I think the code is pretty self explanitor...
Hello. I've created a .NET Add-in that is supposed to do something when a project is being built. I know there are several ways to build a .NET project a) Hitting F5 button b) From Build menu c) From Debug menu ( by debug-ing ) d) By building the solution ( builds the project checked for 'Build' in solution properties ) e) By right-clic...
I'm building a website and I'd like to avoid using asp.net membership. I want to consider some alternatives before I decide to write this code from scratch. Are there any open source projects that tackle the authentication problem? note: I need user/pass auth (can't use Open Id). ...
Visual Studio 2008 SP1 doesn't provide any language pack prerequisite for the .NET Framework 3.5 SP1. My research results are: it should be easy to create a custom bootstrapper package that installs a language pack. I've downloaded the Bootstrapper Manifest Generator. It's really a nice tool to create custom packages, but I don't know w...
