Screenshots of framed website

by Tech Support on Thu Mar 02, 2006 7:02 am

Hi,

if you want to take a screenshot of a website which is divided into frames and some frames are so big that scrollbars are shown, the SAVEAS TYPE=BMP command does not save those bits of the page which are not shown - as it does when the page is not divided into frames.
This VBScript parses through the frameset of the page and visits all source of the frames seperately to take a screenshot of them. If you use this program, please let me know if it works and, more importantly, if it doesn't.
Here is a short explanation
You have to do the following. Copy the text at the end of these explanations into an empty file (using, e.g., notepad) and save it as yourfilename.vbs on your hard drive. The file name is not important, the file ending .vbs, however, is.
Once you have done that you should be able to double click the file, which will then open the iMacros Browser and go to a framed website and save screenshots of the full frames in you InternetMacros/downloads directory.
To adjust this file to your needs, you need to edit it a little. Under "place your macro code here" you need to place your macro code, which brings you to the site you want to take a screenshot of. Place your macro code between two " and end each line with

& VbCRLF & _

except the last line. Leave the

"SET !EXTRACTADD {{!URLCURRENT}}"

as the last line - you must not remove that line, otherwise the script will not work!
If you need further code after the screenshots have been taken (e.g. for logout), add the code after "place your other macro code here (if needed)".

Regards
