@sree.harsha,

Is your code the exact same code as the sample, or were any changes made ?

Error ThrowMaxNameTableCharCountExceeded seems to indicate that a string was too long.

A few pointers which might help you identify what is wrong:

  • Are you using a valid DSS username and password ?
  • Was the WSDL added to the project ? Was it updated ?
  • Try commenting out sections of the code to find out which one generates the error. Is it in section Get API version, Validate an Instrument, or Re-assign credentials variable ?

As a side note: if you are at the start of a new development project, you should use the REST API. Both the SOAP and REST APIs are currently supported, but SOAP will be phased out. REST is the way to go.
