Screen scrape catastrophic error


Just started getting this error on a workflow that previously worked perfectly:

Message: Scrape round table: Catastrophic failure (Exception from HRESULT: 0x8000FFFF (E_UNEXPECTED))

Source: Scrape round table

Exception Type: ActivityException

Please can anyone help?



Fixed - seems the “Screen Scrape” activity has gone. Replaced it with “Get Full Text” and it worked.

Please note that there never was a Screen Scrape activity but a wizard.

The wizard generates depending on the target application:

  • Get Full Text
  • Get Visible Text
  • Get OCR Text

Thanks Badita, are you sure about that though?

Here were the properties for this step before I fixed the “catastrophic error” (this used to work perfectly):

And here’s what I had to change it to (as no longer a “Screen Scraping” activity in the toolbox):
