I am extracting data of searched users on Facebook. I am doing ‘extract corealated data’ to get Name, URL and other details. But the extracted datatable does not have any data. I am using message box to show contents of datatable but it is blank. What could be the possible reason. Please help.
@shrutika Rename ur datatable and see
Can you post the workflow screenshot pls? How are you creating the data table and adding data to it?
I tried renaming datatable but still the same issue
@shrutika Is it possible to share your workflow or Url that your trying to scrap data
datatable is initialised ‘New System.Data.DataTable’ by default. Removing this gives Null pointer error.
I am scraping data from facebook. Steps are:
- Login
- Search user from search box
- Click on People button to see all the users
- Scrap data
You need to use the ‘output datatable’ activity to parse it to a string, then you can display it in the message box.
Update: @shrutika have you tried this?
@shrutika I just done i am getting results. you delete extract structure data activity and try
If I delete extract structured data activity how would I get the data?
Are you suggesting to delete and redo Scraping? I have done this but still facing same issue.
The above workflow used to work earlier, but I am facing this issue after I made some changes in other part of the project. Could changing scope of datatable help?
@shrutika Redo Scraping but before that create one Datatable after scraping in the extract structure data actvity remove default variable and assign you created Datatable
This also is not working
@shrutika data table wont display in message box after scraping use for each row and see data is scraping or not
I have three sequences-Login, Scraping and Logout. The scraping does not work after I put it in a separate sequence. It works when I keep all these in single sequence. How do I make scraping work if I have to keep these different sequences?
@shrutika When you put sequence to separate sequence in the variable panel change scope to sequence
I have kept the scope to global, still facing same issue. Attaching the workflow.Main.xaml (188.4 KB)
@shrutika candidates_city_company_details.csv file needed
candidates_city_company_details.zip (460 Bytes)
Can someone please help me out with this? Its urgent and I am not able to find a solution for this problem.
