RoboTask forum

Hi, i have a problem making a screenshot and i don't know how to solve the failure.

First load a website using Internet Explorer; the embedded browser doesn't work with the special site i need.
e.g. https://climate.rutgers.edu/snowcover/c ... 5&ui_set=2

I need the grafic (but it's some xml etc.)... ok.

Maximize the IE.
Do a screenshot... pause... bla bla... convert.

It work's fine when i test it!

...but... when i use the schedule the task stops... aborting with "Das Handle ist ungültig" (The handle is invalid) ...u can see the screenshot at the attached file.

What am I doing wrong?

Send the task and whole task log to me for investigation, please (oleg(at)robotask.com)

Sent the task-file to you via mail.

I reproduced your problem.
It seems you try to take a screenshot in RDC (remote desktop connection)
It works fine if session is opened and not locked.

BUT if you lock the session it takes a snapshot of lock screen
If you disconnect the remote session the task get error "Handle is invalid" this error is not appear in local console, because local console is always connected. But you will get the screenshot of your lock-screen

You have to take a snapshot from the window, because the window always alive in the session.
BUT (again) Internet Explorer sometimes gives an empty screenshot.
You can take snapshot twice.
take snapshot, wait 1 sec and take snapshot again. Second screenshot always corrected
I tried this on RDC, with locked session and in disconnected session. It works.

Unfortunately other browsers (Chrome, FireFox) always gives empty screenshot

I will send the corrected example to you
