INPCameraCollection::Enum

[TDV]

Hello! I got a problem calling INPCameraCollection::Enum. If I start operating system with already attached cameras and launch my application the program hangs up calling INPCameraCollection::Enum:

CComPtr CameraCollection;
CameraCollection.CoCreateInstance(CLSID_NPCameraCollection);
this->DispEventAdvise(CameraCollection);
[color:#FF0000]CameraCollection->Enum();[/color]

I have such problem with OptiTrack�s samples too. I tried to switch on/switch off devices before calling INPCameraCollection::Enum, but it didn�t helps. After detaching all cameras it works well. May be somebody knows how to solve this problem?

Is your application being launched automatically at system startup, or manually?

If you'd like, we can send your software to support@naturalpoint.com and we can test it here.

As I wrote earlier, such problem I have with OptiTrack�s samples too. I sent my software to support@naturalpoint.com at the beginning of April with "Blank Frames" problem, but didn't receive an answer until now.

Would you like to do such experiment on your computer? You need at least two cameras FLEX V100 (with one camera it works well), PC, OptiTrack sample OptiTrack_sample_VC8b_v31 from web site and 10-15 minute of time.

Thanks

Hello! Can you say anything about this and my previous ("Blank Frames") problems? May be you can say approximate date of testing or something like this?

Thanks

I had the same problem, if I start operating system with a camera attached and launch my application the program hangs up calling oCameraCollection.Enum() in VB !!!!! If I disconnect the camera and reconnect it works fine.

Installing the Public Beta - Version 1.3.037 beta 1 of the SDK sorted my issue.
