System.AccessViolationException

[voxxxo]

I don't know if someone face this problem before, I am using C# and C++ with smile.h to develop a web service. everything is fine, deploy it to the IIS server, I loop for few time to read the xsdl fie, i get this error:

System.AccessViolationException: Attempted to read or write protected memory. This is often an indication that other memory is corrupt.
at DSL_network.{dtor}(DSL_network* )

Can it be because I did not clear the belief?

No, I would check the return value of FindNode call; maybe your 'node' parameter is incorrect (node identifiers in SMILE are case-seensitive).

It return a result for three time then the system corrupted.

It return a result for three time then the system corrupted.

You should explicitly check the DSL_node pointer before dereferencing it and calling Value() method:

DSL_node *p = theNet.GetNode(theNet.FindNode(node));
if (p == NULL)
{
// can't find node by its id
}
