Learning Initatives Automation Starter

Checking SendWindowMessage made it work.

thank you @suraj.setty, I did go through the video and the UiPath docs stating difference in the various input properties before asking here.
Click activity in my application with default properties didnt work, and then I tried other combinations i.e: enabling / disabling SimulateClick and SendWindowMessage but in the end checking SendWindowMesage fixed. This seems contrary of default method being work 100% so I really wanted to understand what magic SendWindowMessage did to fix the issue?
There was a point when it says enabling SendWindowMessage makes OS to work with application so want to understand this more.

Hello @ramvashista85

Please see the below explanation which can give clear overview.

DEFAULT

How does it work?
Clicks: the mouse cursor moves across the screen
Typing: the keyboard driver is used to type individual characters

SEND WINDOW MESSAGES

How does it work?
Replays the window messages that the target application receives when the mouse/keyboard is used
Clicking and typing occur instantly

SIMULATE

How does it work?
Uses the technology of the target application (the API level) to send instructions
Clicking and typing occur instantly
