Microsoft Visual Studio

Question : What is CLI ( Common Language Infrastructure) ?

VS.NET is just an editor, provided by Microsoft to help developers to write .NET programs easily. VS.NET editor automatically generates lot of code, allow developers to drag and drop controls to a form, provide short cuts to compile and build the application etc.

VS.NET is not a required thing to do .NET programming. You can simply use a notepad or any other simple editor to write your .NET code. And you can compile your .NET programs from the command prompt. The following is the list of some of the features of Visual Studio .NET:

1. Visual studio automates the step required to compile source code.
2. The Visual Studio text editor is very intelligent; it can detect errors and suggests code as appropriate as you required.
3. The Visual Studio designer for Windows Forms and Web Forms applications, allowing simple Drag and drop design of User Interface elements.
4. The Visual Studio contains many powerful tools for visualizing and navigating through the elements of our projects, whether they are C# code files or other resources such as bitmap images or sound files.
5. The Visual Studio enables us to use advance debugging techniques when developing projects, such as ability to step through code one instruction at a time while keeping an eye on the state of our application.

Question Write short notes on windows forms.

Windows forms (also called Win Forms) ate used to create GUI-for Windows desktop applications. The idea of Win Form has been borrowed from Windows Foundation Classes (WFC) which was used for Visual J++. Win Form provide an integrated and unified way of developing -GUI. It has a rich variety of windows controls and user interface support.
Numerous classes and functions were used by programmers to handle GUT. MFC in VC++, direct API in C++ and VB Forms Engine in VB are just a few examples of different ways of handling GUI.
Simply Win Form is just another group of wrapper classes that deal specifically with GUI. Win Form classes encapsulate the Windows Graphical APIs. Now the programmers would not need to use the Windows Graphical APIs directly; and since Win Form has been made apart of .NET. Class Framework; all the programming languages would use the same Win Form classes. This would rid the programmers of the need to learn different� GUI classes/tools. Win Forms in the part of the namespace System Winforms.
With Win Forms we can make a single user interface, and use it in VC++, VB, C#. Using
Visual Studio. NET simply designs the GUI, by dragging the controls on a form (something that all VC++ and VB programmers are well familiar with). Now you can use the same form either in VB, VC++ or in C#. And this is all made possible because Visual Studio.NET uses the System. Winforms namespace to draw the GUI. And any language that has the appropriate CLS compliance can use this form directly.
