Internet PlugIn

Internet PlugIn

The Internet PlugIn realizes higher level network functions than the Network PlugIn: you can easily use it to communicate with servers using the HTTP and the FTP protocol.

As opposed to the Network PlugIn, you are limited to these to protocols, but you can realize functions such as connecting to a server and downloading a file with only one command!

You really don't need any prior knowledge in network programming to use this PlugIn, but you should know Instant.EXE at least to the level of the beginner's guide.

As a network administrator, for example, it should be fairly easy to create a custom backup tool that saves data to a remote FTP server within minutes, but possibilities range from there to custom download managers and the like!

To demonstrate how easy the usage of the Internet PlugIn really is, here is an example of how to get the HTML code of a webpage with only two Internet PlugIn commands. Well, the whole script has a couple of lines of code, but these are used to build the GUI of the script.

I will not explain the section at the beginning of the script (creating the window) any further at this point. The subroutine that is executed when the button is clicked (:: iX_Display_Control(btnGetSrc)) is the interesting part. The internet-command creates a connection to the server the user entered and gets the HTML of the specified file (usually index.html, if none is entered) into the variable, all in ONE command!

To have a nicely formatted output of the text, the "modify text"-command is used to convert the newline (ASCII 10) to the Instant.EXE 3.0 newline character (^M). Next thing to do is write the HTML code from the variable to the label in the window. Finally, the HTTP connection is closed. Since we only have one connection at the time in this little script, we would get along fine without doing this, but for the sake of clean programming you should get used to closing the connection anyways.

*** Create display window, display controls and wait for user interaction
Display Window 'Get HTML source' (ID='', X=31, Y=31, B=150, H=80, Max. enabled, Inner size)
Display Control Label: 'URL:' (ID='lblURL', X=5, Y=3, B=9, H=4)
Display Control Input: 'http://' (ID='inpURL', X=17, Y=2, B=68, H=5)
Display Control 'Get page source' (ID='btnGetSrc', X=88, Y=1, B=60, H=7)
Display Control Input: (ID='inpPageSrc', X=5, Y=10, B=143, H=66, multiline, Slider)
Wait infinite...

:: iX_Display_Control(btnGetSrc)
*** Create connection and save data to variable
Internet in [PageSource]: (URL '[iX.Display().Control(inpURL).Text]', get file)
*** Replace newline character with Instant.EXE 3.0 newline (^M)
Modify text '[PageSource]' into [PageSource] (Search for '[ix.ASCII 10]', Replace with '^M')
*** Display page source HTML
Set in [iX.Display().Control(inpPageSrc).Text]: '[PageSource]'
*** Close connection
Internet in [Result]: (close connection)
Return
