This member of RFTerminal Object is supported on iOS, Windows Mobile, Windows CE, Palm, and DOS.
The SetBackLight method remotely sets the amount of inactive time, in seconds, that may pass before an RF device automatically turns off its display back light.
VB
bStatus = object.SetBackLight (nTimeout)
VC++
HRESULT hr = object->SetBackLight (short nTimeout, 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
|
nTimeout |
The number of seconds of inactive time that may pass before an RF device automatically turns off the display back light. |
Remarks
For network efficiency purposes, any changes made to an RF device will not take effect until the SetTerminalInfo Method is called. This allows you to change multiple options through the use of a single radio packet rather than using a radio packet for each option.
Note, if the backlight timeout value is more than the keytimeout value, the device will completely power itself down before the back light is ever deactivated.
