Re: Auto Read another apps form contents

Tech-Archive recommends: Fix windows errors by optimizing your registry

thanks mr. unreliable. here are the details. the app that needs to obtain
text content/
images is a windows pgm that will be written in vb6 using XP os. The donor
pgm.
has sotware installed on the desktop, but links up to a server using the
internet.
i'm not entirely sure if the donor pgm uses the browser, but i assume it would
use the browser to some extent. The key is i would be limited to obtaining
this info
only from what is available on my computer. Say can i read aqn image of their
window and make out the text content on it, etc. By the way if a solution
exists
i understand vb will probably have to use api. i'm more looking for pseudo
code
with a few comments. thanks again.
