EDSDK callbacks not working

I have a working command line application, using EDSDK v2.13.

However, when I register callbacks, there is a burst of property events then nothing.

I have remedied this a loop like this:

while(!_kbhit())
{
  EdsOpenSession(camera);
  Sleep(10);
  EdsCloseSession(camera);
}

This seems horribly kludgy. Is the SDK broken, or am I missing something?

Canons EDSDK is stuck in the 90s, terrible to use. And after a few days of playing with it, it seems much less sophisticated than Nikons.

These companies should implement an http based API on all their cameras like Sony is doing.

If you're using the EDSDK on Windows, you have to have a Windows message loop in your main thread, otherwise callbacks won't happen. (This is because the EDSDK uses the obsolete COM STA threading model instead of real threads.)
