Question

One of the problems I often run into, is that I will include ‘Windows‘ in my uses clause, and then I will later add ‘JwaWinBase‘ for some specific calls.

However, many of the functions in the ‘Windows’ unit are the same as in JwaWinBase, and I start getting errors in my main unit, all over the place, until I fix all my calls by pre-pending the correct unit name, like this:

Old:

• CreateProcessAsUser(…)

New:

• Windows.CreateProcessAsUser(…)
• JwaWinBase.CreateProcessAsUser(…)

What I want to know, is if there is a way to have the unit name automatically pre-pended to every call to a function in another unit? This way, before I added JwaWinBase to my uses clause, I could have the ‘Windows’ unit name pre-pended to any function calls. Then adding JwaWinBase wouldn’t give me any errors.

I’m currently using Delphi 2007.

Answer 1

There isn’t.

However, the function calls are handled in the reverse order they’re in the uses clause, so that if you have this:

uses   Windows, JwaWinBase; 

… it will call Jwa functions by default. However, if you reverse them:

uses   JwaWinBase, Windows; 

… it should call the Windows functions by default, and you can preface your Jwa functions as required.
