RE: Object reference not set to an instance of an object while recall transaction

you are getting the null exception as your trying to make a call from a null object which cause the object not set to an instance error

as you can see form below it appears that 'this.Application' has null value which mean you are using it in the code in some please were it is not initialized yet
