Restore Form/Program to the Original or Saved State
Download Restore Form / Program to the Original or Saved State

Three unique ways of reseting your program's data and controls to their initial state or restoring them to a saved state. This method has some great side effects. You can use multiple data classes to hold your data and not have all of your data loaded into memory at the same time. You can load only the data/variables that you need for a section of your app when you need them saving on memory consumption.

The use of pure data classes are a great way to only load the data variables when you need them so that they don't take up memory while not in use. This can be very helpful in large programs which store the data variables in modules. These modules will be in memory the whole time but the data classes can be destroyed when you are finished with them conserving memory usage.
