Kinect for Windows V2 - kinect-sdk

Question

In my project I need to detect multiple gestures, I made a .gbd file with 2 continuous gestures. I can detect the continuous gesture when the .gbd file had one gesture. When there is 2 gestures I am unable to read any one gesture. Do any one know the reason? Here I post my code. I used Body basics example from sdk, and added necessary functions separately to avoid memory leakage.
//separate function to initialize database, vgb frame source and vgb frame reader
void CBodyBasics::InitializeVGB()
{
HRESULT hr;
std::wstring sDbFile = L"ContinuousGestures.gbd";
hr = CreateVisualGestureBuilderDatabaseInstanceFromFile(sDbFile.c_str(), &m_pGestureDatabase);
if (SUCCEEDED(hr))
{
OutputDebugString(L"Success DB\n");
}
else
{
OutputDebugString(L"Failure DB\n");
}
for (int i = 0; i < BODY_COUNT; i++)
{
// Source
hr = CreateVisualGestureBuilderFrameSource(m_pKinectSensor, 0, &m_pVGBFrameSource[i]);
if (SUCCEEDED(hr))
{
OutputDebugString(L"Source created\n");
}
else
{
OutputDebugString(L"Soure creation failed\n");
}
// Reader
hr = m_pVGBFrameSource[i]->OpenReader(&m_pVGBFrameReader[i]);
if (SUCCEEDED(hr))
{
OutputDebugString(L"reader opened\n");
}
else
{
OutputDebugString(L"No reader\n");
}
}
}
//function to find the available gesture count, add the available gestures to source
void CBodyBasics::CheckGestureMultiple()
{
HRESULT hr;
hr = m_pGestureDatabase->get_AvailableGesturesCount(&iGestureCount);
//gesture count
if (SUCCEEDED(hr))
{
OutputDebugString(L"gesture #\n");
}
else
{
OutputDebugString(L"0 gesture\n");
}

OutputDebugString(smessage);
hr = m_pGestureDatabase->get_AvailableGestures(iGestureCount, m_pgesturelist);

Is there wrong in my code? Do I need to modify my code? Can anyone help me?
