Starting Apps Most users use the GUI and
either
Double click a desktop icon
Select a list item from the Program menu
You can also issue commands through the command line interface
Copyright 2012 by Janson Industries8
Starting Apps When you run a application in
Windows, you are specifying an executable file name
For instance, clicking the IE icon tells Windows to “run” iexplore.exe in C:\Program Files\Internet Explorer\ C:\Program Files\Internet Explorer\
iexplore.exe is a fully qualified name
Copyright 2012 by Janson Industries9
Starting Apps If the fully qualified name is not
specified, Windows searches the Environment Variable called PATH for locations to look for it
Let’s prove it. Start the command prompt
Start button, All Programs, Accessories, Command Prompt
Copyright 2012 by Janson Industries10
Running a pgm In command prompt we specify
iexplore.exe “Not recognized” message
Now specify fully qualified file name (in quotes) IE started
Copyright 2012 by Janson Industries11
Running a pgm▮ Now we will set the path value
path = "C:\Program Files\Internet Explorer\"
In command prompt we specify iexplore.exe IE started
