ShellExecute

[chssoccer 0]

If I want to call a function in an compiled script could I use ShellExecute like this to do it?:

ShellExecute("ahkscript.exe", "functionnamethatneedstobecalled")

No

The second argument is for command line parameters. This passes strings to the application.

If it is an autoit script, look up 'Command Line Parameters' in the AutoIT help file.

Only if your compiled script looks like this:

If $CmdLine[0] > 0 Then
    Switch $CmdLine[1]
        Case 'functionnamethatneedstobecalled'
            functionnamethatneedstobecalled()
    EndSwitch
EndIf

Func functionnamethatneedstobecalled()
    ; Do stuff
EndFunc
