Hello!!!
I`m new using Optitrack cameras. I`m doing project and I want that camera images show in form panel. This is my code:


pCamera->Start();
INPCameraFrame * pCameraFrame;
pCamera->GetFrameById(1, &pCameraFrame);
pCamera->DrawFrame(pCameraFrame,this->panel1->Handle.ToInt32());

pCamera is INPCamera * pCamera and panel1 is System.Windows.Forms.Panel

when I try to run, the program return a box message with the next error message:

See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.

************** Exception Text **************
System.AccessViolationException: Attempted to read or write protected memory. This is often an indication that other memory is corrupt.

I'm using visual 2005 and the project is in windows forms

any idea?? can you help me??

thanks!!

I haven't tried displaying camera images by passed a winforms panel although I'm sure it's possible. You might consider utilizing the GetFrameImage call to pull the image data and display it yourself. Check the samples for how to do that.
