Hello!
I work with Citrix environment and I use SendHotkey and Clipboard to get the data from the Citrix.
What I do:
1 - Use SendHotkey (TAB) to go with the cursor on the field that I need to extract the information
2 - Use SendHotkey (Home, SHIFT + End) to select entire text from the field
3 - Use SendHotkey (CTRL + C) to copy the selected text
4 - Use ‘Get From Clipboard’ Activity to get the content from clipboard and assign to a variable
Hope It Helps!
