Android Question Use if in the Process_Globals in Code Module

SMOOTSARA · Apr 17, 2021

Hi

Is it correct to use "if" in the Process_Globals section?
For example the following code

B4X:

in Code Module


Sub Process_Globals
    
    If Application.VersionCode =1 Then
        Dim str1 As String = "ver_1"
        Else
        Dim str1 As String = "-----"
    End If
    
End Sub

If it works, it is correct

While you can get away with it most times it is not recommended to run code in the Process_Globals and Globals Subs.

For good style you should really set a default value in Process_Globals and reset it if necessary in Activity_Create.

Correct. For "good style", however, you shouldn't even set the variable values there.
I think that is a special case, where a variable is used as if it were a constant (but dependent on...) and so I would say that way can be acceptable... as exception.

It is not correct. The global subs should only be used for variables declarations and simple assignments.
This code might break in the future.

Tip: the less you use code modules the better.
