Windows GUI automation - Text box Lost focus event not triggered - (Moved)

Recommended Posts

Hi team,

I'm automating a Windows GUI with AutoIt v3.3.8.1.   When i'm setting the text by ControlSetText, the text box lost focus event not triggered.  But the windows GUI working fine in try manually.  If the event trigger properly, the Windows GUI auto enabled 6 text boxes [ref: Manual Run.png]

Code Snippet

ControlSetText($hWnd,"","[NAME:txtMsgLen]", "0006")


By any chance shall we force the Windows GUI Lost Focus event of a text box?  Any help is much appreciated.

Moved to the appropriate forum, as the Developer General Discussion forum very clearly states:


General development and scripting discussions. If it's super geeky and you don't know where to put it - it's probably here.

Do not create AutoIt-related topics here, use the AutoIt General Help and Support or AutoIt Technical Discussion forums.

Have you tried ControlSend ($hWnd,"","[NAME:txtMsgLen]", "{TAB}") instead of Send () ?

Hi, thanks for your reply. 

Yes i tried, not working in automated way.  Only manual screen navigation TAB is working fine. Need to force call the Lost_focus with dllcall kind?
