Windows.Net Forms Interview Questions

  1. What is Syntax of a simple Windows Forms MessageBox statement

    System.Windows.Forms.MessageBox.Show("Hello World") 

  2. 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

  3. 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.

  4. 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.

  5. 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#.

  6. 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.

  1. ow do you create a separator in the Menu Designer?

    A hyphen '-' would do it. Also, an ampersand '&\' would underline the next letter.

  2. what are the diffrences between windows application and windows service?

    Windows service is used for back end processing like printing,creating setup of CD.it is not used for Gui application.
