Activate sorting using GUICtrlRegisterListViewSort without mouse

JohnBailey · April 16, 2007

Primarily, I'm trying to figure out how to do the sort on initialization of the GUI. I'm not asking for you to write the script (because I don't want you to). I want to learn this, but I'm stuck!

#include <GUIConstants.au3>

Global Const $LVM_GETITEM           = $LVM_FIRST + 5
;Global Const $LVM_FINDITEM         = $LVM_FIRST + 13
;Global Const $LVM_SETSELECTEDCOLUMN    = $LVM_FIRST + 140

Dim $nCurCol    = -1
Dim $nSortDir   = 1
Dim $bSet       = 0
Dim $nCol       = -1

$hGUI   = GUICreate("Test", 300, 200)

$lv     = GUICtrlCreateListView("Column1|Col2|Col3", 10, 10, 280, 180)
GUICtrlRegisterListViewSort(-1, "LVSort") ; Register the function "SortLV" for the sorting callback

$lvi2   = GUICtrlCreateListViewItem("DEF|444|11.05.2005", $lv)
GUICtrlSetImage(-1, "shell32.dll", 12)
$lvi3   = GUICtrlCreateListViewItem("CDE|444|12.05.2004", $lv)
GUICtrlSetImage(-1, "shell32.dll", 3)
$lvi1   = GUICtrlCreateListViewItem("ABC|666|10.05.2004", $lv)

You can send an "LVN_COLUMNCLICK" notification within a "WM_NOTIFY" message directly to the GUI.

http://msdn2.microsoft.com/en-us/library/ms930204.aspx

You have to build a NMLISTVIEW-struct and fill in the members with the proper values.

If you need any further detailed help just post it.

JohnBailey · April 17, 2007

you are my hero! Thank you! Wondeful idea. I look into it and begin testing, and post any more Qs I have. I'm excited now that I have a direction and I'm not just taking wild guesses. :shocked:

Zedna · June 21, 2007

I'm trying to do the same but no luck.

It's sorting OK after click on first column but _SendMessage() with WM_NOTIFY and LVN_COLUMNCLICK do nothing.

Can somebody help me with this?

Here is my small testing script for WM_NOTIFY and LVN_COLUMNCLICK

I'm trying to have sorting by first column at start.

Just modify one(two) line(s):

DllStructSetData($struct_NMLISTVIEW,1,GUICtrlGetHandle($ListView1)); here is the handle to the control needed not the GUI window handle

Uncomment the right line:

_SendMessage($Form1, $WM_NOTIFY, $ListView1, DllStructGetPtr($struct_NMLISTVIEW))

Thank you very much Holger!! :rolleyes:

It works like a charm now.

here is whole corrected working script for other peoples interested in this
