ListView - WM_DrawItem not work with WM_Notify

[Trolleule]

Hey peoplez,

In All i try to have a listview control which subitems have InputBoxes instead of simple Text. I have a good start, by creating an Edit control with _WinAPI_CreateWindowEx and position it right. That works great.

Then I set the row height of a listview item, because the Edit controls are too small. For that problem i found this code:

expandcollapse popup

#include 
#include 
#include 
Global Const $ODT_LISTVIEW = 102
Global Const $ODA_DRAWENTIRE = 0x1
Global Const $ODA_SELECT = 0x2
Global Const $ODA_FOCUS = 0x4
Global Const $ODS_SELECTED = 0x0001

Global $default_font = "Arial"
Global $default_font_size = 9
Global $GUI_main = GUICreate("", 300, 300, -1, -1, -1, $WS_EX_ACCEPTFILES)
Global $hGUI_tab_listview[2][10]
GUIRegisterMsg($WM_MEASUREITEM, "WM_MEASUREITEM") ;place before listview creation - message sent once for each ownerdrawn control created
$hGUI_tab_listview[0][0] = GUICtrlCreateListView("", 15, 68, 250, 90, _
BitOR($LVS_REPORT, $LVS_SHOWSELALWAYS, $LVS_OWNERDRAWFIXED), _
BitOR($LVS_EX_FULLROWSELECT, $LVS_EX_GRIDLINES)) ; + $LVS_EX_CHECKBOXES + $LVS_SINGLESEL
GUICtrlSetFont(-1, $default_font_size + 8, 400, 0, $default_font, 5)
_GUICtrlListView_AddColumn(-1, "Name")
_GUICtrlListView_SetColumnWidth(-1, 0, 155)
_GUICtrlListView_AddColumn(-1, "Count")
_GUICtrlListView_SetColumnWidth(-1, 1, 72)
For $i = 0 To 10 ; populate the listview for testing purposes
_GUICtrlListView_AddItem(-1, "test " & $i)
_GUICtrlListView_AddSubItem(-1, $i, $i, 1)
Next

GUIRegisterMsg($WM_DRAWITEM, "WM_DRAWITEM")

"ptr", DllStructGetPtr($iSubItmRect), "int", $local_alignment)
Next
;#ce
EndSwitch
EndSwitch
Return $GUI_RUNDEFMSG
EndFunc ;==>WM_DRAWITEM

That works fine too. It's an UDF and the user used WM_DrawItem

Now I try to have Edit Controls + adjusted row height. I combined both, but have problem, when i resize a column. When i resize the column, the edit control resizes too, but then the items are gone.

Here the code where i combined both:

Sorry the code has no order, you can see i made a lot of tests there but damn nothing seems to work nearly.

I have no idea how i get it to work, please help me!

Thank you guys!
