LoadPreferences() effects SpacePilot Display only once

[mist-sc]

Hello!

I need to change SpacePilot display text dynamically. Do perform this I create my config file and use it in LoadPreferences() function. But then I change some buttons titles in config file during my program runtime. As I understand, I should reload preference page from config file. So I call LoadPreferences() once more, it returns S_OK, but there is no effect until I manually reload preferences file in 3DConnexion Control Pannel.


LoadPreferences() returns S_OK even if I stop driver before the call.

Here is my code, maybe someone can help me to find out what is wrong.

Code: Select all

HRESULT hr;
CComPtr<IUnknown> _3DxDevice;

// Create the device object
hr = _3DxDevice.CoCreateInstance(__uuidof(Device));
if (SUCCEEDED(hr))
{
            //CComPtr<ISimpleDevice> _3DxSimpleDevice;
	hr = _3DxDevice.QueryInterface(&_3DxSimpleDevice);
	if (SUCCEEDED(hr))
	{
	   // Get the interfaces to the sensor and the keyboard;
	   g3DSensor = _3DxSimpleDevice->Sensor;
	   g3DKeyboard = _3DxSimpleDevice->Keyboard;

	   // Associate a configuration with this device
	  if(PathFileExists(filename.GetString()))
               {
		_3DxSimpleDevice->LoadPreferences(_T("NameFromEXECUTABLES"));
	   }
	   // Connect to the driver
               _3DxSimpleDevice->Connect();
 	   _3DxSimpleDevice->get_Type(&type);
            }
	else
	{
	   return _EMPTY;
	}
}
else 
             return _EMPTY;
return _OK; 

After this I have my config loaded and everything is OK.

But then I modify congif file and want to reload it:

Code: Select all

CComPtr<IDispatch> _3DxDeviceN; 

// Get the device object 
g3DKeyboard->get_Device(&_3DxDeviceN); 
CComPtr<ISimpleDevice> _3DxSimpleDeviceN; 

HRESULT hr = _3DxDeviceN.QueryInterface(&_3DxSimpleDeviceN);
if (SUCCEEDED(hr))
{
	_3DxSimpleDeviceN->LoadPreferences(_T("NameFromEXECUTABLES"));
}

LoadPreferences() returns S_OK but nothing happens. I'he tried to load configs of other programs -> no results.

I've tried to close the driver and call CoCreateInstance again, but my application crashed or hung during the call.

After some experiments I get that LoadPreferences() calls correctly only once.

Thanks for your help!
Maxim.
