Hi.

First of all, very nice work. I added it to the list of Gui related scripts.



One problem, tho, very serious: when you resize column, script blocks and burns CPU. Thats something I often encounter when implementing custom controls and its always about message monitoring (subclass, onmessage....).

You have 2 places where that happens: OnNotify and LV Scrolling and both may crash the AHK. Keep in mind that it can be more or less problematic on any particular computer, you maybe never encountered it so far. On my PC, each time I move column, it crashes (Vista, Quad Core).


Adding critical 500 to mentioned functions seem to solve the problem. I am not yet sure if it rly solves it, but it will definitelly work better. In my work sometimes even that doesn't help much.

when using it, having my content of listview sometimes totally disappear and my script hang out.

There is about 1400+ line in the listview and problem is totally random.

any idea ?
I think i have got 1 time theproblem when not using LVA too ... but wasn't sure. Anyway without LVA i don't think having listview bug

Using demo script just scroll faslty the listview will make the list bug randomly

thanks for the script. i hope it will be updated.

anyone know if similar methods could modify individual TreeView branch colors?

I'm insufficiently fluent in AHK to write a script like this myself, but I may try to convert the original, or the one by evl this script was based on, into a treeview version; but it would be trial and error stuff...

well this script is excellent, however i haven't the skills yet for fix it.

I think the problem is on the event handler or the way it's done.

[majkinetor]

You should all try what I described above. It should solve the problem.

i have add critical 500 :
Critical 500
OnMessage("0x4E", "LVA_OnNotify")

Don't seems fix problem for me.
When application freeze, if i click on trail icon, it's continue a bit to unfreeze the scrolling (but not totally)

Another problem:
This script works great, but after generating so many rows it will stop coloring them..

Any way to adjust this to show text in a cell with a progress bar? If not regular listview text then possibly custom text through gdi?

[majkinetor]

To fix freezing bug you can also try this:

1. Remove subclassing. Put return in lva_Subclass function as first line.
2. Put critical 500, in lva_OnNotify function.

Sorry for the bump, but I need some help here.

I'm using LVA to highlight a cell in a Listview, like in Excel. A user can navigate with the arrow keys and enter data into certain cells.

The problem I'm having is that the listview is on a second gui. When you destroy and reopen the Gui, I run into both lagginess and a redrawing problem. Does LVA not handle a destroyed and recreated Listview?

I'm calling LVA_ListViewAdd and OnMessage("0x4E", "LVA_OnNotify") whenever I create (and recreate) the listview. Could this be the problem too? If so, which should I only call once?

Thanks.

I tried, but of course failed, it seemed simple but apparently not for my elementary abilities. Is it possible that someone could develop a function to draw a line through the cell to create a strike through look?

I tried to mess with the progress bar function to draw a line instead of a rectangle, place it centered in the cell and blah blah blah but I just don't quite understand the full functionality of the code yet.

If no one else does it I'll be continuing to try and figure this code out since it will help me learn anyway. If I ever get it I'll post my attempt at it lol.
