Summary
The GetScreenText method is one of the three methods that do screen scraping in the Distinct VT220 ActiveX control. It allows you to scrape a section of the screen and pass the data to a buffer.
Syntax
String GetScreenText (x1, y1, x2, y2)
| |
x1 |
is the position of the first character that you want to scrape |
| |
y1 |
is the position of the first line from which screen scraping is to start. |
| |
x2 |
is the position of the last character of the text portion that you want to scrape |
| |
y2 |
is the position of the last line of the text that you want to scrape |
Description
The GetScreenText method allows you to screen scrape portions of text that is displayed in a VT220 emulation window and pass this to a buffer. This means that if you have an application which displays data in
predefined positions you can easily scrape that data by calling this method with the specified co-ordinates for the first and last characters of the text to be captured, and pass it to your
application.
For this method to succeed the CaptureScreen property must be set to TRUE.

"The night before I went on summer
holiday we had to make some 'last minute' configuration changes to
approx.
300 routers, a tedious job to do manually with telnet. We went along with
MS
Excel containing a list of IP-adresses to the routers, and the VIT
telnet-component. One hour later the VBA-application (small is beautiful)
was working, and after another hour all of our routers were updated with
the
new configuration. I just say a big "Thanks" to you all for a good sleep
that night."
