This member of RFTone Object is supported on iOS, Windows Mobile, Windows CE, Palm, and DOS.
The AddTone method lets you add a specific note to an RFTone object.
VB
bStatus = object.AddTone (nFrequency, nDuration)
VC++
HRESULT hr = object->AddTone(short nFrequency, short nDuration, BOOL *bStatus);
Return Value
|
bStatus |
The status of the function returned as Boolean True or False values. Use the RFGetLastError method to return the error value. |
Parameters
|
nFrequency |
The frequency for a single tone defined in numeric hertz (cycles per second). |
|
nDuration |
The duration of time the tone will play measured in milliseconds. |
Remarks
Individual notes are stored within an RFTone object, each note defined by a frequency and a duration. Once defined, a specific note will remain within an RFTone object until either the object is released or all notes are cleared from the object using the ClearTones Method. This allows you to use a single tone object within your application that may be modified rather than creating a new tone object for each use.
Example
See the PlayTone Method.
