Ok - I finally managed the version 3.3.6 to work in Borland C++ Builder. I replaced the Borland function CreateComObject() by the Windows function CoCreateInstance: //m_pDev = CreateComObject(CLSID_Device); CoCreateInstance(CLSID_Device, 0, CLSCTX_INPROC_SERVER | CLSCTX_LOCAL_SERVER, IID_IUnknown, (...

Hello, yes, I verify the device pointer before using it. If I would release the device pointer it also would be invalid in version 3.2.2 - but in this version it works. This is the source: m_pDev = CreateComObject(CLSID_Device); if (!m_pDev) { return false; } hr = m_pDev->QueryInterface(&m_pSimp...

The problem is the QueryInterface() call - the creation of the COM object works fine also in version 3.3.6 - the debugger shows two new threads t...

Hello,

With version 3.2.2 I can also receive and handle sensor input events. There is also no splash banner that gets c...
