SAPGUI scripting works in AutoIt but not in luacom

[WladyslawMotyka]

Hi folks,

I need help with connecting to SAPGUI using Lua. I saw that you folks have scripts for connecting and automation of SAP gui.

I try to use Lua and its LuaCOM but it did not work for me.

Have anybody ever try it?

My script bellow always fail on this call application:Children(0) and LuaCOM crash.

I don't know what am I doing wrong.

Could anybody help me with this? I would be grateful.

Welcome to AutoIt and the forum!

Why not use AutoIt as it works and LUA doesn't?

Hi,

our entire project is based on Lua so ... I am choosing an easier way :-)

I'm not sure you will get a lot of help on this subject.

SAPGUI automation using Autoit is not very widely used. And I don't know how many users of this forum do it with LUA.

Ok, but stil, i will wait a little and try my luck with this forum :-)
