Android Question Why Code Module doesn't support CallSub(Me, aFunction)?

[Roberto P.]

I need to check if it exists and to launch a function within a module code with:

If SubExists(Me, aFunction) Then
        CallSub(Me, aFunction)
end if

B4A but does not allow it.

How can I do this test?

Thank you

 

[Roberto P.]

because I created a "dynamic" system works so I do not know the name of the function before
thanks

You can create a class, instead of a code module; simply move all routines there

Because I need to to call the static function of the form of several parts

Code modules in B4A do not have a context of their own so they cannot intercept events. Classes share the same context as the module that initialized them so they can handle events.

clear.

Create the class, then a Public object of type YourClass (a good place is the Starter service) and you can call its methods from all other modules, as if it were a code module (Starter.YourObject.MethodOne(param1,...))

thank you is what I did (but I wanted to avoid)

but I wanted to avoid

Why? What is the problem?

If you have a code module you must call its routine writing also the code module name:
MyModule.MyRoutine

Same if you use an object:
' MyClass

' Starter (or elsewhere)
Public objMyClass As MyClass
init...

Starter.objMyClass.MyRoutine

So, to call the routine you have to write also Starter before. Not a big difference

no problem. I had to implement the method you describe. I wanted to understand why there are limits on Code Module.

Thanks for the answers
