Running a repeated process in a folder

[Trancedified]

Hello,

I have a VB app that does this process in order:
1) Open a folder and for each file, delete the last 3 lines
2) Use the commondialog control to open a file in the same folder
3) Extract pertinent information from that file (the location of each extracted string is in the same place every time)
4) API usage: import the file into a specialized database

How would you automate this process so that in step 1 & 2, I won't have to choose a folder and file manually, it'll extract all the info I need for every file in the folder? The way I was thinking this app would run is if it monitors a folder periodically and if it notices that more files got added into it,
run the above process.

Also, how would you make this app like a service or something that starts up when Windows does?

Here's my code:
