Applicaiton crashes while adding and removing rows into/from a table

[Noam Wolf]

Hi Neel

The exact thing you are describing happened to me too. It's a linkage
problem of the dll. When I built the agent++ and the snmp++ AND my agent
module - all three as static libs, everything went fine, and there was no
problem in "if (value) delete value;".
You have to make sure that all your libs use the same flags (I am compiling
with "debug multithreaded dll" flags in VC++).
In my case there was no problem using a static lib.

Hope it helped.

Noam Wolf.

table


Hi Mailing List,

I have implemented an Agent using SNMP++ and Agent++. 
For using SNMP++ and Agent++, I have combined files of both SNMP and Agent 
to make a DLL using VC++ on windows NT. I link with the library file
generated along with
the DLL for creating my executable. I have created a MIB that contains a
Table 
and some non-Table objects. I add the my mib to the mib object defined in
Agent.

1.	Now when I try to add a row, my application crashes at the statement
- 
		if (value) delete value;
	in the function MibLeaf::replace_value(SnmpSyntax* v). 
	When I commented the line, I could add rows into it and perform get
and 
	get-next operations on it. 
2. 	When I try to delete an added row, similar type of problem occurs.
	This time the application crashes at the statement
		if (t) delete t;
	in the function
		OidList<MibTableRow>::remove(Oidx *);
When I tried to debug using NuMega Bounds Checker, it gave the message:
	Memory allocation conflict
	Memory was allocated in module pdemain.exe
	Freed in module snmp.dll
The same error comes in case of #1 too.

If you have any idea of what goes here, please help me overcoming this
problem.

Thanking you in advance,
Neel
