- Write a simple Windows Forms MessageBox statement.
System.Windows.Forms.MessageBox.Show
("Hello, Windows Forms");
- Can you write a class without specifying namespace? Which namespace does it belong to by default??
Yes, you can, then the class belongs to global namespace which has no name. For commercial products, naturally, you wouldn’t want global namespace.
- You are designing a GUI application with a window and several widgets on it. The user then resizes the app window and sees a lot of grey space, while the widgets stay in place. What’s the problem?
One should use anchoring for correct resizing. Otherwise the default property of a widget on a form is top-left, so it stays at the same location when resized.
- How can you save the desired properties of Windows Forms application?
.config files in .NET are supported through the API to allow storing and retrieving information. They are nothing more than simple XML files, sort of like what .ini files were before for Win32 apps.
- So how do you retrieve the customized properties of a .NET application from XML .config file?
Initialize an instance of AppSettingsReader class. Call the GetValue method of AppSettingsReader class, passing in the name of the property and the type expected. Assign the result to the appropriate variable.
- Can you automate this process?
In Visual Studio yes, use Dynamic Properties for automatic .config creation, storage and retrieval.
- My progress bar freezes up and dialog window shows blank, when an intensive background process takes over.
Yes, you should’ve multi-threaded your GUI, with taskbar and main form being one thread, and the background process being the other.
- What’s the safest way to deploy a Windows Forms app?
Web deployment: the user always downloads the latest version of the code; the program runs within security sandbox, properly written app will not require additional security privileges.
- Why is it not a good idea to insert code into InitializeComponent method when working with Visual Studio?
The designer will likely throw it away; most of the code inside InitializeComponent is auto-generated.
- What’s the difference between WindowsDefaultLocation and WindowsDefaultBounds? WindowsDefaultLocation tells the form to start up at a location selected by OS, but with internally specified size. WindowsDefaultBounds delegates both size and starting position choices to the OS.
- What’s the difference between Move and LocationChanged? Resize and SizeChanged?
Both methods do the same, Move and Resize are the names adopted from VB to ease migration to C#.
- How would you create a non-rectangular window, let’s say an ellipse?
Create a rectangular form, set the TransparencyKey property to the same value as BackColor, which will effectively make the background of the form transparent. Then set the FormBorderStyle to FormBorderStyle.None, which will remove the contour and contents of the form.
- How do you create a separator in the Menu Designer?
A hyphen ‘-’ would do it. Also, an ampersand ‘&\’ would underline the next letter.
- How’s anchoring different from docking?
Anchoring treats the component as having the absolute size and adjusts its location relative to the parent form. Docking treats the component location as absolute and disregards the component size. So if a status bar must always be at the bottom no matter what, use docking. If a button should be on the top right, but change its position with the form being resized, use anchoring.

In ASP.NET version 3.5 Service Pack 1, you can define the capabilities that a browser has in the following ways:
· At the machine level, you create or update a .browser XML file in the following folder:
\Windows\Microsoft.NET\Framework\v2.0.50727\CONFIG\Browsers
After you define the browser capability, you run the following command from the Visual Studio Command Prompt in order to rebuild the browser capabilities assembly and add it to the GAC:
aspnet_regbrowsers.exe –I c
· For an individual application, you create a .browser file in the application’s App_Browsers folder.
These approaches require you to change XML files, and for machine-level changes, you must restart the application after you run the aspnet_regbrowsers.exe process.
ASP.NET 4 includes a feature referred to as browser capabilities providers. As the name suggests, this lets you build a provider that in turn lets you use your own code to determine browser capabilities.
In practice, developers often do not define custom browser capabilities. Browser files are hard to update, the process for updating them is fairly complicated, and the XML syntax for .browser files can be complex to use and define. What would make this process much easier is if there were a common browser definition syntax, or a database that contained up-to-date browser definitions, or even a Web service for such a database. The new browser capabilities providers feature makes these scenarios possible and practical for third-party developers.
There are two main approaches for using the new ASP.NET 4 browser capabilities provider feature: extending the ASP.NET browser capabilities definition functionality, or totally replacing it. The following sections describe first how to replace the functionality, and then how to extend it.
