SpaceNavigator, MFC 64-bit, UNICODE, VS2008, cant find dev

[jdbrinton]

Straight up from the textbook...

Code: Select all

CFrameWnd::Create(........)
{
	SiOpenData oData;
	SiInitialize ();
	SiOpenWinInit (&oData, GetSafeHwnd());
	if ((m_DevHdl = SiOpen ("Buddy", SI_ANY_DEVICE, SI_NO_MASK, SI_EVENT, &oData)) == NULL )
	{
		char buf[1000];
		sprintf(buf, "no supported 3DxWare device\n");
		AfxMessageBox(L"no supported 3DxWare device\n",0, 0);
		SiTerminate();
	}
	else
	{
		AfxMessageBox(L"3DxWare device found!\n", NULL, MB_OK);
		SiSetUiMode (&m_DevHdl, SI_UI_ALL_CONTROLS);
	}
}

never finds the device.

I compiled siapp using the source code found in the 3Dconnexion 3DxWare SDK/lib/siapp/src.... Totally helpless here.

thx for your help![/code]

That code looks reasonable. I'd make sure the hwnd you are sending exists.

You probably want to make a scg file for your app, but it isn't necessary.

Take a look at the driver's log file to see if it is complaining about your connection request. Turn on the log file in the 3DxWare GUI. It is saved in %appdata%/3dconnexion/3dxware.

Why did you recompile siapp? Use the libs we ship if possible. Make sure you have the latest SDK from the archive section of our web site.

Hi jwick, thanks for the reply.

Here's the log when I attempt to run the code below:

21:11:32.807: UdCtl: Protocol 30 request to open connection for hwnd 0x0.
21:11:32.807: UdCtl: Open request denied due to bad parameters.
21:11:32.807: Driver Si: Attempt to call UdCtlOpen failed

Frappin' frap! It looks like from CFrameWnd::Create I must call the parent call first before getting a HWnd. The following code works:

Code: Select all

	// Initialize 3DxWare

	CFrameWnd::Create(lpszClassName, lpszWindowName, dwStyle, rect, pParentWnd, lpszMenuName, dwExStyle, pContext);

	SiOpenData oData;
	SiInitialize ();
	SiOpenWinInit (&oData, GetSafeHwnd());
	wchar_t buf[1000];
	wsprintf(buf, L"GetSafeHwnd: 0x%016x\n", (long long)GetSafeHwnd());
	AfxMessageBox(buf, 0, 0);

	if ((m_DevHdl = SiOpen ("App name", SI_ANY_DEVICE, SI_NO_MASK, SI_EVENT, &oData)) == NULL )
	{
		SiTerminate();
		AfxMessageBox(L"Sorry - No supported 3DxWare device available.\n", NULL, MB_OK);
	}
	else
	{
		AfxMessageBox(L"3DxWare device found!\n", NULL, MB_OK);
		SiSetUiMode (&m_DevHdl, SI_UI_ALL_CONTROLS);
	}
	return 1;

Thanks for the log suggestion, I wouldnt've got it w/o!

Isn't there a better place to put that code? OnInitDialog or something that gets called after the whole create process is done?
