List COM port problem(Subscript used on non-accessible variable)

[BernyHsu]

Hi everyone,

I am using martin's UDF to query my COM ports. Here is my code:

#include <CommMG.au3>
#include <MsgBoxConstants.au3>

Global $portlist = _CommListPorts(0)

For $i = 0 To $portlist[0]
   MsgBox( $MB_SYSTEMMODAL, "", $portlist[$i])
Next

I've already put CommMG.au3 and commMG.dll in the same directory. When I use Tools => Go in Autoit SciTE-Lite everything is fine. The program print out all my COM ports. But when I compile this program to an EXE file and execute it. An error occurs as following:

This is so confusing. I try another experiment that removing commMG.au3, then Tools=> GO again. It shows the error like it is in EXE:

Is this indicating that something wrong in #include <CommMG.au3> ???

Thank you for your great support!

 

 

My code is packaged as an attachment.

After posting this topic, I tried compile this code as x86 script instead of x64. It works! But another question is that: Is it possible to package dll with exe together? Just found out that I cant leave the exe file alone without commmg.dll Thanks again and excuses me for disturbing posts.

I reproduce the problem when I use _CommListPorts() without parameter.

You can add a MsgBox to see if the returned value is a string :

Global $portlist = _CommListPorts()
MsgBox(0, "", $portlist)

use _arraydisplay to debug.

Search the help file for FileInstall.

Search the help file for FileInstall.

Thanks! I'll try it out later and update the result here.
