how to change the code to QM code

[conanjou]

how can I change the code as red color below to QM code ：

COM methods, need to be registered to the system, the class name: sy.dt

Shell "regsvr32 / s sydt.dll"
Set sydt = CreateObject ("sy.dt")

or

LoadLibrary to load DLL, do not register with the system

LoadLibrary ("sydt.dll")

Thanks in advance!
