Proper Way To Implement Global Constants Plus Memory Considerations

I am new to Visual Studio and Visual Basic, but I am a revived dBase, FoxPro, Visual FoxPro, ColdFusion programmer..I'm as good once as I ever was.So I am looking for how to implement some constants for the three main reasons anyone would want to use global constants:Readability, Maintenance,Memory Usage.For example in a list of error return codes, I may assign "File Not Found" an error code of 1010.To create a constant that exists only within a procedure, declare it within that procedure.To create a constant available to all procedures within a class, but not to any code outside that module, declare it in the declarations section of the class.To create a constant that is available to all members of an assembly, but not to outside clients of the assembly, declare it using the..Friend keyword in the declarations section of the class.To create a constant available throughout the application, declare it using the Public keyword in the declarations section [of] the class. global it is visible to all procedures and modules that comprise the application. Global variables and constants, as with Module level variables, must be declared outside of any procedures in the Declarations section and must use the Public keyword.The language above stating "Global variables and constants, as with Module level variables..." insinuates to me that Global Constants and Module Level constants are different, thus having different scopes.

And I have yet to see ANYWHERE that tells me to put stuff in the Declarations Section of a class or program or application, tell me just WHERE the declarations section actually IS! They always give the code of how to declare (I can do this...) but they don't say where the code GOES.I know I am overlooking the simplest of things, but just trying to be very sure of what I am doing.[code]
