Data Scraping - intermittent error

Help
1

Hi everbody,

I am trying to solve a problem using Data Scraping but it is not working fine. Sometimes during Extracting Wizard process I receive the message “Error HRESULT E-FAIL has been returned from a call to a COM component”. I have tried Chrome and IE … in both work different… the message appear in different places, but the error message appear.

That’s not the worst thing… I divided the Scraping in 4 parts and during the RUN, the extraction stopped in different points. Sometimes stopped in part 1, sometimes in part 3, etc…

I think the problem is the webpage size ! It is so big. I have installed .NET Framework and change the webbrowser.

Basically I must extract full data, put it inside a DataTable and read it in another moment.

Could somebody give me a support ?

Make sure the checkbox for ContinueOnError is checked in the data scraping activity. Just make sure it’s not set to False, as this will always result in the activity resulting in an error.

Hi dear,

I have done but the problem is that during Wizard we can’t set this option, can it ?

You won’t be able to do this through the wizard, but you can modify the resulting activity once you reach the end of the wizard.

Ok. I will try.

Unfortunately ContinueOnError checked no good result. Application continue stopping in different points.

Can you upload a screenshot of the error, the activity where the error occurred, and show us the parameters passed to the activity where the process failed?

As in the Print example the wizard show us error message after choose a column - I was using IE… using Chrome the error message show us at the 3rd column.

Hi, are you making sure you start scrapping only when the page has finished loading? Cause i did wait before scrapping with chrome and had no problems.

Of course Yes. At the end appear (http://www.pricecryptocoin.com/). For me the issue show in “inicio” . COuld you share with me your XAML?

Hi, mine only had the data scraping activity… but i did it with chrome. Did you have the error on execution right? Not on the wizard phase.
