Custom Query

DllStructGetData() truncates the last element of a (char/wchar) array to ensure null termination. The code needs modified to secretly allocate a larger buffer and secretly insert a null terminator outside the user-requested bounds so the user's data is not altered.

This is a display-only issue, the underlying data is not changed.

Touched commands: Check, Select, Expand

Checking/Selecting/Expanding is done in treeview but @error is set to 1 though. Note: Exists command works OK and doesn't set @error to 1

Here is test script: No messageboxes should appear but for Check, Select, Expand commands they appear with value=1 (@error)

#include <GUIConstants.au3>

$gui = GUICreate("ControlTreeview test", 212, 212)
$treeview = GUICtrlCreateTreeView(6, 6, 200, 160, BitOR($TVS_HASBUTTONS, $TVS_HASLINES, $TVS_LINESATROOT, $TVS_CHECKBOXES), $WS_EX_CLIENTEDGE)
$h_tree = ControlGetHandle($gui, "", $treeview)

$root = GUICtrlCreateTreeViewItem("Root", $treeview)
$item1 = GUICtrlCreateTreeViewItem("Item 1", $root)
$item2 = GUICtrlCreateTreeViewItem("Item 2", $root)
$item3 = GUICtrlCreateTreeViewItem("Item 3", $root)
$item4 = GUICtrlCreateTreeViewItem("Item 4", $root)
$item41 = GUICtrlCreateTreeViewItem("Item 41", $item4)
$item42 = GUICtrlCreateTreeViewItem("Item 42", $item4)
$item5 = GUICtrlCreateTreeViewItem("Item 5", $root)

GUISetState(@SW_SHOW)
ControlTreeView ($gui, "", $h_tree, "Expand", "Root")

$ret = ControlTreeView ($gui, "", $h_tree, "Exists", "Root|Item 4")
If @error Then MsgBox(0,"Exists",@error) ; here it is OK
;~ MsgBox(0,"Exists return",$ret) ; here it is OK
ControlTreeView ($gui, "", $h_tree, "Check", "Root|Item 4")
If @error Then MsgBox(0,"Check",@error) ; here should be @error = 0 but it is 1
ControlTreeView ($gui, "", $h_tree, "Select", "Root|Item 4")
If @error Then MsgBox(0,"Select",@error) ; here should be @error = 0 but it is 1
ControlTreeView ($gui, "", $h_tree, "Expand", "Root|Item 4")
If @error Then MsgBox(0,"Expand",@error) ; here should be @error = 0 but it is 1

While 1
	$msg = GUIGetMsg()
	Select
		Case $msg = $GUI_EVENT_CLOSE
			ExitLoop
	EndSelect
WEnd

Note: This script could be used in AutoIt helpfile as example script for ControlTreeView() - there is no example script

_ClipPutFile seems to drop the drive letter. However I can paste to explorer.

#include <Misc.au3>

FileChangeDir("E:\")
FileWriteLine(@MyDocumentsDir & "\test.txt", "Bla");
_ClipPutFile(@MyDocumentsDir & "\test.txt");
MsgBox(0, "", ClipGet());
FileDelete(@MyDocumentsDir & "\test.txt");
