You have to use the code module name.

B4X:

codeModule.Load_Screen_Resolution(Activity)

Ok I added that so the call is now:

B4X:

Code.Load_Screen_Resolution(Activity)

Now the compiler is complaining about the property .Width in the If statement:

B4X:

Sub Load_Screen_Resolution(Activity)
   If Activity.Width > Activity.Height Then

So apparently Activity isn't being 'seen' as coming from Main.

What if you removed Activity?
Sub Load_Screen_Resolution
....
End Sub

Code.Load_Screen_Resolution

You have to pass the values to the Sub, like this:

B4X:

Sub Load_Screen_Resolution(aWidth as int, aHeight as Int)
    If aWidth > aHeight Then ...

Calling the Sub:

B4X:

Code.Load_Screen_Resolution(Activity.Width, Activity.Height)

Ok that worked. My last hurdle to clear is calling a Sub in the Code module that is in Main. The same Sub will be in my Setup module so in Code the call will have to go to either Main or Setup modules:

B4X:

Sub Load_Screen_Resolution(aScreenWidth As Int, aScreenHeight As Int)
   If aScreenWidth = 960 AND aScreenHeight = 540 Then

   Load_Landscape_960x540x240_Screen_Resolution

        'the above line is red and is in the Main module. But Main. doesn't work,
        'the compiler says unknown member
   End If

I need to be able to call this sub above Load_landscape...() in either the Main or the Setup modules.

Check in the help for CallSub.

In this case you would use:
CallSub(Main, "Load_Landscape_960x540x240_Screen_Resolution")

How do I step into the CallSub(Main...) with the debugger?

I ran the debugger but it didn't step into the called sub routine CallSub(Main, "Load_Landscape_960x540x240_Screen_Resolution" )

Hi
I have the same problem as post 8 but the post didn't get an answer
I want to call a Sub in Main from a code module but doesn't get called when following it in the Debug(rapid).
This is an old post so maybe "rfresh" found the answer but didn't post it
Thanks
