@Larry, Help!

[this-is-me]

I am just trying this. Don't put too much value on whether or not I can finish the project. I know little about DllCall, so I thought I would ask the man most suited for the task.

I have tried to attach a syslistview item to a gui form. Here is my current code:

expandcollapse popup

#include <guiconstants.au3>

$ID_LISTVIEW = 100
$LVS_REPORT = 0x0001
$LVS_EDITLABELS = 0x200

$LOGPIXELSX = 88
$LOGPIXELSY = 90

$DIRECTION_VERTICAL = 1
$DIRECTION_HORIZONTAL = 0

GuiCreate("Test")
$parhwnd = WinGetHandle("Test")
guisetstate()

$listhwnd = DllCall("user32.dll", "hwnd", "CreateWindow" ,"str", "SysListView32", "str", "", "long", BitOr($WS_CHILD, $LVS_REPORT, $LVS_EDITLABELS), "int", 0, "int", 0, "int", 100 * TwipsPerPixelX(), "int", 100 * TwipsPerPixelY(), "hwnd", $parhwnd, "int", $ID_LISTVIEW, "int", 0, "none", 0)
msgbox(0,"",@error)

sleep(5000)


func GetDC($hwnd)
   $ret = DllCall("user32.dll", "long", "GetDC", "long", $hwnd)
   Return $ret[0]
EndFunc

Func ReleaseDC($hwnd, $hdc)
   $ret = DllCall("user32.dll", "long", "ReleaseDC", "long", $hwnd, "long", $hdc)
   Return $ret[0]
EndFunc

Func GetDeviceCaps($hdc, $nindex)
   $ret = DllCall("gdi32.dll", "long", "GetDeviceCaps", "long", $hdc, "long", $nindex)
   Return $ret[0]
EndFunc

func TwipsPerPixelX()
   $dc = GetDC(0)
   $ppi = GetDeviceCaps($dc, $LOGPIXELSX)
   $dc = ReleaseDC(0, $dc)
   return 1 / 1440 * $ppi
EndFunc

func TwipsPerPixelY()
   $dc = GetDC(0)
   $ppi = GetDeviceCaps($dc, $LOGPIXELSY)
   $dc = ReleaseDC(0, $dc)
   return 1 / 1440 * $ppi
EndFunc

Have I missed something?

Thanks, Larry. I am seeing a small white box for the first time... Kinda exciting.

BTW, What's the main diff between CreateWindow and CreateWindowEx?

[this-is-me]

Oh well, thanks.

[this-is-me]

Thanks a lot Larry, for the $parhwnd, I had it that way at the first, but was wondering (when it didn't work) if the handle returned was not a windows handle, but an Au3 handle. Either way, Can you see any workarounds for any way to add items to the listview that does not require a structure?

[this-is-me]

Well, At least I got a little bit further in my efforts than I would imagine most would have gome.

Are you going to put the SysView in Scripts and Scrapts when it's finished?! I want this function, it would be pretty neat, keep up the good work = D

[Valik]

It is done, he can't do any more to it, specifically, its not possible to make work, so its just pointless (Aside from some hopefully gained knowledge on how DllCall works for this-is-me).

@ Valik,

From this-is-me: Don't put too much value on whether or not I can finish the project.

[Valik]

Thats nice. Did you bother to read the rest of the thread? Particuarly the part where Larry said:

Nope, that cute white square is what you get until AutoIt 3 GUI has listview support... sorry...
