Scapping a WinForm

[scottf35]

Hi,

I need to be able to scrape a winform and save the contents to a file.
The user can either pass in the handle to the form or scape the chose
the form with focus.

Can someone please direct me to a link that would help or explain how
to do this (just the scapping and windows handle bit)?

Thanks!

Thanks for Responding!

Looking back on my spelling attempt for that question I don't know how
you made hide-nor-hare of it. But you seemed to know exactly what i
meant!

I can find the handle to the form ok, but I can't seem to find an API
to let me copy the contents of it.

I could use sendkeys and send a ctrl+a and ctrl+c but obviously I would
rather stay away from that method if I could.

Any ideas of any API's for copying the contents of a form?

BTW it is going to be HTML after all but the only native methods I know
of in .net for copying HTML is with the URL to the server and not the
handle of the form in the window.

Cheers.

Did you miss the link to the sample above?

Thanks for the link but I need to capture all the text in a window not
just what is showing on the screen.

The example app seems to show how to take an image of whats on the
screen as it uses DC and GetWindowRec and creates BitMap's.

To do that, you'll have to use p/invoke. Relevant functions: 'FindWindow',
'FindWindowEx', 'EnumWindows', 'EnumChildWindows',
'GetWindowText'/'SendMessage' + 'WM_GETTEXT'.
