Canon EOS SDK (EDSDK): no operations after starting live view -


i implementing console application (going dll) controls canon eos 600d using edsdk, implemented in c++.

i can function work, change properties, take photos, start live view, , download live view content following examples documentation , sample app.

however, after start live view, although works fine, cannot send further commands or change further properties on camera. so, example, can't start autofocus or take picture once live view begun, though these commands work fine otherwise.

the commands send fine (edssetpropertydata , edssendcommand return 0), nothing happens. in sample, can execute commands after switching live view. gives?

i don't know code if have made loop live view maybe can't go out can't access rest of code.

if case try launch download of liveview timer able continue execution of code.
