I want to write a program in WPF but not sure should I target .net35 or .net30. The advantages of .net35 are obvious. But still, I see one major advantage of .net30 -- it's built into Vista, so, the people using Windows Vista will not have to download and install the framework. Do you think the advantages of .net35 outweigh the hassle o...
Hi, I have a Windows.Forms component which has a "mySize" property that returns a Size struct. My intention was to have this property calculate the returned mySize automatically based on the size of the component, unless mySize has been explicity set, in which case, return the set value of mySize. Unfortunately, now that I am embedding t...
Is it possible to capture the graphics object created by the Google Earth browser plugin from a .NET WebBrowser control? With this graphics object I could create an image to use as the background image for a panel that I can then draw on top of.

I am writing a survey application, and I have a form that can have potentially hundreds of input fields. How would I write the controller to process this form? I can't specify each input as a parameter for the controller, that would be unrealistic. I found out about the MVCToolkit, and the UpdateFrom() method, but is this the right ...
I'm looking into creating a system / site which includes a website. I would like to get the benefits of WPF, and WBA seems to be a good avenue of doing this. Silverlight on the other hand is also good for accomplishing this goal, with the difference that WBA provides more options and power than Silverlight. What are the benefits / losse...
With Regex::Replace we can use $1, $2, ... to match corresponding groups. But how can I use $1 followed by number. E.g. to replace 6 with 678? Regex::Replace(text, "(6)", '$178'); ...
Ok, I have code that is working (posted after this) but before I expand it I wanted to throw it out here and see maybe better ways of doing what I am doing. the problem: the SIP panel sucks - sometimes all I need is numbers or letters entered into a mobile application - most of my users wind up not using the stylus but fingers so I need...

This is probably really obvious and I'm being dense. In C# I can do this: string = @"this is some preformatted text"; How do I do this in VB? ...
Hey! I have a listbox like so: list.DataSource = bindingSource; list.DisplayMember = "column_name"; Later I would want to get the selected item's ID from the DataSet with bindingSource.Current. I've done this before with bindingNavigator+bindingSource, Current returns a DataRowView, so I can cast it and I'm done: Int32.Parse(((DataRo...
Our client (a winforms app) includes a file-browser. I'd like the user to be able to open the selected file using the shell's default handler. How do I do that? I've read that I should use the Win32 API rather than the registry, but I'd prefer a solution that involves only .NET. ...

I manage to do that in a tricky way for email window (following this article). But I didn't find any way to access the current selection in the ...
I am new to testing and mocking. I'm trying to test a business logic class which performs calculations, calls into the DAL and updates the database, and manages transactions. I'm using mocks to do unit testing, but how does full integration testing fit into all of this. Do I basically have the exact same tests, but use the real DAL or do...

I have come across some articles on the web about .Net applets and I was wondering how it differed from an activex control (created using a .Net language)? (to clarify, this is with regards to applets that run inside a web-browser) (Is the difference: ActiveX controls written in a .Net language are called .Net Applets?) Are there any a...
