PowerSNMP for ActiveX

PowerSNMP for ActiveX Manager Control

Use the Manager ActiveX control to easily add SNMP manager functionality to your application. Provides an easy-to-use interface that handles the details of querying SNMP agents.

• Start() method turns on asynchronous processing to receive Inform and Trap messages (raises Inform and Trap events)
• Build a request message by setting properties, adding variables (OIDs) using simple Variable objects, and sending it using
  - GetResponse() sends the request message to a single agent, returning a response message
  - GetResponses() sends the request message to a broadcast address, returning an array of all response messages received
• Walk() sends multiple messages to a specified agent, returning a list of variable values that exist under the specified root OID (retrieving all table values in one easy step)
  - Specify whether GetNext or GetBulk messages should be used, what the timeout should be, and whether the method should attempt retries
  - Use the return value as a flat list, or use ToTable() to format variables into a dimensional array indexed by row and column
• GetResponse(), GetResponses() and Walk() can be executed using three possible threading techniques (for optimal operation in any environment)
  - Free-threading operation is used for environments like ASP, services, or console applications where no message loop is present
  - Pseudo-blocking operation is used to block execution and process the message loop while work executes on a worker thread
  - Asynchronous operation is used for event-driven environments like VB6, where the request executes on a worker thread and raises an event when finished
• Discovery of v3 authoritative engine ID, time, and boots is automatic ... just address an Agent using an IPEndPoint object and discovery happens automatically
• Discovered authoritative engine parameters are cached and efficiently reused for successive requests
