windows - How to call Submit from Credential Provider -

as far understand, when user presses submit button eventually, getserialization method called login details.

i programming credential provider waits external signal log in, , not want user press submit button.

is possible trigger submit event credential provider?

i found way it. trick not call submit button, use icredentialproviderevents::credentialschanged method. have thread running, trigger credentialschanged. enable new credential logs user in.

this shown in microsoft sample samplehardwareeventcredentialprovider.

it worth notice windows logonui automatically selects new credential. not know if in documentation, behaviour experienced.
