Similar to this behavior from AutoCAD:

I know to place the code in the edit boxes g-label subroutine, so it updates the ListView as the user types.
I also found Rajat's old 320mph, NODE, and other names for his fast, but extremely complex and obfuscated search utility. It's also used in Lintalist, Columbus search, and CSVQF (CSV Quick Filter).
I also found just_me's LV_EX library which has a function that returns an object for the matched rows/columns, but again the syntax is weird, and unfortunately if I can't understand it I've found in the past that I can't maintain or really improve/build upon the script.
So I'm looking for the most AHK-vanilla or plain way to update/filter a listview's rows based on an edit control's contents, as the user types, even at the cost of slower performance (but hopefully not painfully slow). I expect my listview to contain about 1000 rows, all in one column, and each column containing no more than probably 5 words.
Here is what I have so far: (attention to the code snippet "; Edit1 Control g-label Subroutine")
Code: Select all

), so that's also part of the reason im trying to keep things stupid-simple, there's a better chance someone can help improve it, or that i'll be able to remember what stuff does later if i improve it
