Console Applications

Visual Studio supports the creation of anu!ber of di1erent t#pesof Applications

*ach di1erent t#pe of Application has adi1erent structure and auto!aticall#

provides support for di1erent applicationscode

2#pes of Applications we will wor3 with inthis course Console Applications

2he Console Class (review)

Console is S#ste! class (it is in the S#ste!/a!espace) $ it is part of the !scorlib librar#which as we have seen is one of the librar#,LLs that is auto!aticall# loaded with thee+ecution of ALL VS applications' !scorlib is discussed in the Chapter 4 Lecture

Set - (around slide 56)' We will discuss.eferences a little later in this slide set'

2his Console class supports a nu!ber of

!ethods& includin" !ethods perfor!in"actions related to 3e#board input (.ead and.eadLine) and screen output (Write andWriteLine)


7/37Slide!

Co!!ents re Console Applications(optional)

.ecall that Visual Studio 5776 provides us with aconvenient interface for applicationsdevelop!ent'

We now e+a!ine the VS 5776 interface for a

Console Application

2he Console Application provides a Module for#ou to write code (a Windows App provides b#default a 8or! for the insertion of tools) 9ouhave a !ini!al set of referenced na!espaces(classes fro! the 8CL) 2here are no classes to support 8or!s or ,rawin"&

etc

Windows of the Visual Studio I,*

Windows are of two t#pes 2ool windows are co!!on to all applications

2ool windows are used for develop!ent in allVisual Studio lan"ua"es

,ocu!ent windows are used to create thevisual interface and code for an application

2ool Windows

2he Solution *+plorer "roups the ele!entsof a solution 2he %roperties window is used to set

properties for objects

2he 2oolbo+ contains controls that arecreated on a for! Several tool windows e+ist for debu""in"

2ool windows can be anchored alon" aned"e of the I,* 2he process is called doc3in" ,oc3ed windows can be Auto Bidden

Auto Bidden windows appear when the !ouseis positioned over the hidden window tab

8loatin" windows appear an#where on thedes3top

So!e tool windows can be con;"ured toappear as docu!ent windows
