Doesn't the use of the "static" keyword retain the value of _CumulativeDataRead as an SBox class member, separate from creation and destruction of the oSBox object?


>Hi there I just noticed a odd behaviour from my class. My class is a class that knows how to connect to a device using the ethernet, send some information to the device, retreive a response from the device and then close the connection to the device. Until now I thought things were going smoothly, but today I wanted to improve the speed of the connect,send,receive, disconnect process.

The object oSBox is scoped to the button click method so you think it would be disposed after the button click method is completed. What I ended up doing, for the time beeing, is to add
