Search "BHO"?

CodePudding user response:

Teacher, I took a BHO (browser help object) its function is used to personalize and customize the browser's new features, and what I want is a generic ocx, not only can be used in the browser, but also need to use c # client, so you have no other solution?

In the callback object pointer and direct control object pointer

CodePudding user response:

Event is written in the thread?

CodePudding user response:

Put the events in the main thread, in the events in the child thread, IE is not detectable

CodePudding user response:

Your callback should be in the child thread triggered, js is single-threaded, so can't catch, you should send a message to the main thread of the window, the window of the main thread to trigger event,
