  • SNMP example of reading values

    This is a simple example of how to read SNMP values across the network from remote SNMP enabled devices like printers, routers, etc.

    Note: in order to compile this example, you will need PB9 and the new include files from Jose Roca's site:
    http://www.jose.it-berater.org/smffo...hp?board=318.0

    His new include files closely match the original C++ include files which covers much more than the ones that came with PB9. For example the ones that came with PB did not have the SNMP stuff. And since they match the MSDN versions, you can see which ones to include based on the API help. I have converted a couple hundred of my programs to using his include files and they only required small changes such as adding additional include statements as needed. I highly recommend them.

    For more information on what MIBs/OIDs to use with SNMP, I recommend
    searching the internet. (ex: http://www.oid-info.com/get/1.3 )

    '  SNMP_Read.bas       by William Burns   (modified on 09/19/2008)
    '
    '  Sample program to show how to read SNMP information using the SNMP
    '  object identifer (also known as MIB)
    '
    '  IMPORTANT:   In order to compile this, you will need PowerBasic 9 and the
    '  full set of WinAPI includes from Jose Roca's site (ver 1.05 or newer):
    '  http://www.jose.it-berater.org/smfforum/index.php?board=318.0
    '   (his include files cover a lot more of windows header files than the
    '    include files that came with PB, so they are definately worth using)
    '
    '------------------------------------------------------------------------------
    '
    ' NOTE:   I did not need to SET/CHANGE any SNMP values so I did not
    ' create a function to set the values.  My program is read only.
    '
    ' But if you need this, it can be done fairly easy using the following:
    '
    ' 1.) use existing code to connect using a community string that has write access
    ' 2.) set up the OID vars and bind them (same as in read function) using something like:
    '      SnmpUtilOidCpy([email protected], ASNOID)
    '      [email protected] = %ASN_NULL
    ' 3.) assign the variable using the correct UDT member according to the type
    '     (this is kinda the reverse of my SNMP_AnyToStr() function)  - let me know if you need help
    ' 4.) call the SnmpMgrRequest() function with %SNMP_PDU_SET instead of %SNMP_PDU_GET
    ' 5.) free the needed buffers and do cleanup.
    ' 6.) Done

    Hi,

    This is the new code for R/W SNMP ...

    Many thanks to William

    Code:
    '------------------------------------------------------------------------------
    '  SNMP_Read.bas       by William Burns   (modified on 09/19/2008)
    '  SNMP_Read.bas       by William Burns   (UPDATED on 10/08/2011)
    '
    '  Sample program to show how to read SNMP information using the SNMP
    '  object identifer (also known as MIB)
    '
    '  IMPORTANT:   In order to compile this, you will need PowerBasic 9 and the
    '  full set of WinAPI includes from Jose Roca's site (ver 1.05 or newer):
    '  http://www.jose.it-berater.org/smfforum/index.php?board=318.0
    '   (his include files cover a lot more of windows header files than the
    '    include files that came with PB, so they are definately worth using)
    '
    '------------------------------------------------------------------------------
    '
    ' NOTE:   I did not need to SET/CHANGE any SNMP values so I did not
    ' create a function to set the values.  My program is read only.
    '
    ' But if you need this, it can be done fairly easy using the following:
    '
    ' 1.) use existing code to connect using a community string that has write access
    ' 2.) set up the OID vars and bind them (same as in read function) using something like:
    '      SnmpUtilOidCpy([email protected], ASNOID)
    '      [email protected] = %ASN_NULL
    ' 3.) assign the variable using the correct UDT member according to the type
    '     (this is kinda the reverse of my SNMP_AnyToStr() function)  - let me know if you need help
    ' 4.) call the SnmpMgrRequest() function with %SNMP_PDU_SET instead of %SNMP_PDU_GET
    ' 5.) free the needed buffers and do cleanup.
    ' 6.) Done
