In Visual Studio .NET the TabStop property is by default set to True for all command and input fields. Most other designers have some concept of tab control for "power users" who don't like to switch to their mouse a lot. This property simply toggles the ability for the control to receive focus when the user hits the tab button to iter...

The situation is this I had a web service that in the client and the server page it had compression and it had encryption.

I've spent quite a bit of time getting familiar with the .NET Stream classes. Usually I learn a lot by studying the class design of professional, commercial-grade frameworks, but I have to say that something doesn't quite smell right here. System.IO.Stream is an abstract class representing a sequence of bytes. It has 10 abstract method/...
Hi, I want to do my component that works similar to most of data controls (MS, Telerek, etc.): myControl.DataSource = new List<myClass>(); mycontrol.NameField = "Name"; myControl.ValueField = "Value"; myControl.DataBind; I have some test code: class myClass { public String Name { get { return _name; } } ... } class c...
Using Seq.cast seems to constantly fail, even for something as simple as the following: let xor c = Seq.cast c |> Seq.reduce (^^^) xor [1;3] // Works, assuming because no cast is necessary xor ['a';'b'] // Fails xor [2u] // Fails The latter two fail with Specified Cast is not valid. What am I missing? I'm trying to use...

What I noticed is that if clock on computer running the applica...

My inclination, correct or not, when creating a thread is that it would be run in the background of the main thread. Thank you for the quick responses. I do provi...
Does anyone know of a tool that can help me figure out why we are seeing runaway CPU in a managed app? What I am not looking for: Process explorer, it has this awesome feature that lets you see CPU per thread, but you do not get managed stack traces. Also, it requires a fairly proficient user. Windbg + SOS, it could probably be used ...
I'm using XDocument and XElement objects to write a large XML file (currently 8MB). I'd like to switch to XStreamingElement so that I can write the file without having all the data in memory at once. Unfortunately, I need to include an encoding declaration. Can I do that without using an XDocument? ...
I see lambda expressions have become a very useful tool at some points in the language. I've been using them a lot and most of the time they fit really nice and make the code shorter and perhaps clearer. Now.. I've seen some , I would say excessive use of them. Some people like them so much that try to use them everywhere they can.. Som...

I am implementing shape resizing using corner handles. In some cases, certain moves with the mouse holding the handle are not legit, e.g. if it will in effect extend it beyond the control boundary. So what I would like to do in this case is "cancel" the mouse move in flight programmatically, so that the mouse would just stay within the b...

I once read a blog post by a dev at Microsoft about the anatomy--what individual pieces of data are combined--of a System.Guid. Does anyone have the link? I'm not finding it by googling. ...
I am trying to make a DIY touchscreen and would like to enter it into the local science fair but wanted to do it on the programing aspect of Multi-touch. My problem lies in that i have never worked with analyzing images (from a USB based web-cam). I would like to do this project in C# if possible (C++ - if worst comes to worst) I need...
We are going through some very interesting debates as to how we should manage errors/issues in our IT department. I would really like to hear what others say about how they manage application/feed, etc generated errors. We are being pushed to put everything into BPEL (Business Process Execution Language) so that the non devs can see w...
