Re: Retrun JS result Tchromium
Thanks for your reply. Just to know if we call postmessage(Handle, MINIBROWSER_VISITDOM_JS, 0, 0);, then the control will go immediately to VisitDOM3Msg.

PostMessage is used to send a message asynchronously :
https://learn.microsoft.com/en-us/windows/win32/api/winuser/nf-winuser-postmessagew
That demo calls PostMessage with "Handle" as the first parameter. That Handle belongs to DOMVisitorFrm (the main form) and the VisitDOM3Msg procedure is declared to be executed when the main form receives a MINIBROWSER_VISITDOM_JS message :
