how the protoolkit works in pro in
The question is a little unclear about where you want to start exactly, however, I can recommend that you start by looking in to the Protoolkit directory inside your Wildfire install directory. There are a lot of examples in the subfolders.
I am not sure, but you may have to reconfigure proe using ptcsetup.bat so that you install the pro/TOOLKIT option before the files are available.
I have provided the PDFs (not all the files) for you here.
how its resitry file is created
these file have complete information but the first program about the hello word is not runing by me
Sorry, I am not sure what a "resitry" file is.
can you send me a hello word or any protoolkit file which you run
before ruuning any protoolkit application a resitry file is required in .dat file
This may shed some light
