NVAPIExample - Unneccessary calls to NeroGetAvailableSpeeds - Club CDFreaks

AndyNugent · 03-05-2006

Is there a reason why the method CSpeedComboBox::RefreshSpeeds() calls NeroGetAvailableSpeeds rather than just using the pnsdi->nsdiWriteSpeeds values passed to it?

The code is currently:



// Open the device...

// 

NERO_DEVICEHANDLE hDevice = NeroOpenDevice (pnsdi);
 

if (hDevice != NULL)

{

	// Get the speeds...

	// 

	NERO_SPEED_INFOS * pSpeeds = NeroGetAvailableSpeeds (hDevice,

														ACCESSTYPE_WRITE,

														MEDIA_CD,

														NULL);

	if (pSpeeds != NULL)

	{

		CString sSpeed;
 

		// Loop through all available speeds and add them to

		// the combobox.

		// 

		for (DWORD i = 0; i < pSpeeds->nsiNumSupportedSpeeds; i ++)

		{

			sSpeed.Format ("%d", pSpeeds->nsiSupportedSpeeds[i]);

			int iIndex = AddString (sSpeed);

			if (iIndex != CB_ERR)

			{

				// Set the item data to be the speed itself in X.

				// 

				SetItemData (iIndex, pSpeeds->nsiSupportedSpeeds[i]);

			}

		}
 

		NeroFreeMem (pSpeeds);

	}
 

	NeroCloseDevice (hDevice);

}

When it only needs to be:



CString sSpeed;
 

// Loop through all available speeds and add them to

// the combobox.

// 

for (DWORD i = 0; i < pnsdi->nsdiWriteSpeeds.nsiNumSupportedSpeeds; i ++)

{

	sSpeed.Format ("%d", pnsdi->nsdiWriteSpeeds.nsiSupportedSpeeds[i]);

	int iIndex = AddString (sSpeed);

	if (iIndex != CB_ERR)

	{

		// Set the item data to be the speed itself in X.

		// 

		SetItemData (iIndex, pnsdi->nsdiWriteSpeeds.nsiSupportedSpeeds[i]);

	}

}

Or am I missing something?

It's me being stupid.

NeroGetAvailableSpeeds() takes into account what disk is in the drive.
