NetworkCardDiscovererSubnetSearch Method (DiscoveryHandler, String, Int32)

public static void SubnetSearch(
	DiscoveryHandler discoveryHandler,
	string subnetRange,
	int waitForResponsesTimeout
)

Public Shared Sub SubnetSearch ( 
	discoveryHandler As DiscoveryHandler,
	subnetRange As String,
	waitForResponsesTimeout As Integer
)

public:
static void SubnetSearch(
	DiscoveryHandler^ discoveryHandler, 
	String^ subnetRange, 
	int waitForResponsesTimeout
)

This method will wait up to waitForResponsesTimeout milliseconds determining that there are no more discovery responses. Subnet searches are defined by the first three subnet octets, followed by a range, such as 192.168.2. This method accepts IP addresses of the form, assuming a subnet of 192.168.2:

• 192.168.2.254 (will send a discovery packet to 192.168.2.254)
• 192.168.2.* (will send a discovery packet for the range 192.168.2.1 - 192.168.2.254)
• 192.168.2.8-* (will send a discovery packet for the range 192.168.2.8 - 192.168.2.254)
• 192.168.2.37-42 (will send a discovery packet for the range 192.168.2.37 - 192.168.2.42)

This method will invoke the FoundPrinter(DiscoveredPrinter) method for each printer that is found during discovery. DiscoveryFinished will be invoked when the discovery is finished and DiscoveryError(String) will be invoked when any errors are encountered during discovery. When DiscoveryError(String) is invoked, the discovery will be cancelled and DiscoveryFinished will not be invoked.

If a printer responds to the discovery request more than once, the FoundPrinter(DiscoveredPrinter) method will only be invoked on the first occurrence.
