LV_ADD not refereshing on second pass

Joe Glines · 29 Dec 2013, 21:41

I'm at my witt's end trying to figure out why the LV_Add (lines 104 to 112) works fine the first time through but when I press "submit" a second time it deletes the listview but does not refresh it with the new data. I've inserted a messagebox showing the data is there and, when looking at it from OutputDebut- the vars look to be holding the exact same information.

I'm SOO close to having an amazingly cool script for running sql on a text file but just can't get this to work. I'd be incredibly grateful if someone could point out my (surely) naïve error.

The problem here isn't that LV_Add isn't working, you're using Gui, Add, ListView incorrectly. Each time the ReturnedItems label is run, you're adding a brand new ListView to the gui. LV_* functions work on the most recently added ListView, which is presumably outside the boundary of the window...

This might demonstrate the problem (modified ReturnedItems code):

Code: Select all

#SingleInstance, Force
#NoEnv

;~ GoSub RegistryCheck
GoSub CreateFiles
GoSub Headers
GoSub BuildQuery
return

RAlt::
Browser_Forward::Reload

Awesome! I understand and have changed my code. Thank you! I don't have it quite where I want it yet but the data does go back into the ListView.
