Help needed with _GUICtrlListView_DeleteItem

lgvlgv · September 21, 2011

I'm to stupid to get it to work!!!

it looks like i find the value but i cant delete the row from "ListViewClients"

here is the code:

Func Disconnect($hSocket, $iError); Damn, we lost a client. Time of death: @Hour & @Min & @Sec :P
local $iIT=""
   $iIT = _GUICtrlListBox_FindString($ListViewClients, $hSocket, True)
    ConsoleWrite('@@(266) :(' & @MIN & ':' & @SEC & ')' & "$iI & $hSocket " & $iIT &"-"&$hSocket& @CR) ;### Function Trace
   $fan=_GUICtrlListView_DeleteItem($ListViewClients,$iIT)
   $fan2 = _GUICtrlListView_GetItemTextString($ListViewClients, $iIT)

   ConsoleWrite('@@(266) :(' & @MIN & ':' & @SEC & ')' & "$fan " & $fan& ":"& $fan2&@CR) ;### Function Trace
    MsgBox(4160, "Deleted?", _GUICtrlListView_DeleteItem($ListViewClients, $iIT))

And here is the result:

See any problem here? :graduated:

What type of control are we actually dealing with here?

lgvlgv,

You are overcomplicating the code:

#include <GUIConstantsEx.au3>
#include <EditConstants.au3>
#Include <GuiListView.au3>

$hGUI = GUICreate("Test", 500, 500)

$hLV = GUICtrlCreateListView("Col 1", 10, 10, 200, 300)
$hLV_Handle = GUICtrlGetHandle($hLV)

For $i = 0 To 9
    GUICtrlCreateListViewItem("Item " & $i, $hLV)
Next

$hInput = GUICtrlCreateInput("", 10, 400, 200, 20)
GUICtrlSendMsg(-1, $EM_SETCUEBANNER, True, "Enter the text of the item to delete")

$hButton = GUICtrlCreateButton("Delete", 10, 450, 80, 30)

GUISetState()

While 1

    Switch GUIGetMsg()
        Case $GUI_EVENT_CLOSE
            Exit
        Case $hButton
            $sText = GUICtrlRead($hInput)
            $iIndex = _GUICtrlListView_FindText($hLV_Handle, $sText)
            _GUICtrlListView_DeleteItem($hLV_Handle, $iIndex)
    EndSwitch

WEnd

You actually only need one line:

_GUICtrlListView_DeleteItem($hLV_Handle, _GUICtrlListView_FindText($hLV_Handle, GUICtrlRead($hInput)))

Does that help? :graduated:

The thing is that i want the program (server part) to automatic add new connected computer to a list <---- This is ok and working.

But when they disconnects or lose connection i want them removed from the list automatic... and the thing i have to find and remove is the Item that have $socket

lgvlgv · September 21, 2011

this is the list.

Melba23 · September 21, 2011

lgvlgv,

the thing i have to find and remove is the Item that have $socket

In the snippet you posted you have this line:

DllStructSetData($tInfo, "Text", $hSocket)

So I presume you have the text of the item to find and delete stored in the variable $hsocket.

My example shows how to find and delete an item from a ListView when all you have is the text - so what is the problem? :graduated:

u have to speak to me like a 5 year old

or u speak over my head

how do i find the ITem with $socket when i search throgh hole list?

the "GUICtrlRead($hInput)" is based on input from guie or im i wrong?

_GUICtrlListView_DeleteItem($hLV_Handle, _GUICtrlListView_FindText($hLV_Handle, GUICtrlRead($hInput)))

/thx Lasse

PS. it has to be done automatic when a client disconnect, the socket are returned to me when i lose a connection all that has to be done is to delete that item that contains the socket from the list. (socket is uniq)

Surely not?

OK, a couple of questions: :graduated:

- 1. Is $hsocket the text we are tring to find?

- 2. If it is the text, is the value in the first column of the ListView?

Now try and run this to see if we can locate the problem:

Func Disconnect($hSocket, $iError); Damn, we lost a client. Time of death: @Hour & @Min & @Sec :P
Local $shit = ""
; Items created using built-in function, pass the control ID
Local $iIndex = _GUICtrlListView_FindText($ListViewClients, $hSocket)
$shit &= "Index = " & $iIndex & " - " & _GUICtrlListView_DeleteItem($ListViewClients, $iIndex)
ConsoleWrite('@@(266) :(' & @MIN & ':' & @SEC & ')' & "$shit " & $shit & @CR) ;### Function Trace
ToolTip("SERVER: Client disconnected. $shit = " & $shit, 10, 30); Placing a tooltip right under the tooltips of the client.
EndFunc   ;==>Disconnect

Post the reslulting line from the console and we will then see if the problem is in finding the item or deleting it.

Be patient - we will get there in the end.

lgvlgv,

As the text we are looking for is not in the first column we need to use _GUICtrlListView_FindInText.

Try this and see what you get:

Func Disconnect($hSocket, $iError); Damn, we lost a client. Time of death: @Hour & @Min & @Sec :P
Local $shit = ""
; Items created using built-in function, pass the control ID
Local $iIndex = _GUICtrlListView_FindInText($ListViewClients, $hSocket)

ToolTip("SERVER: Client disconnected. $shit = " & $shit, 10, 30); Placing a tooltip right under the tooltips of the client.
EndFunc   ;==>Disconnect

I hope you are having fun!

P.S. What are you using to create the ListView - the native GUICtrlCreateListView command or the UDF _GUICtrlListView_Create function? If the latter then use GUICtrlGetHandle($ListViewClients) in that snippet. :graduated:

ops sorry about the caps :graduated:

Melba23 · September 21, 2011

lgvlgv,

$shit Index = 0 - False

That shows that the item is being found - 0 is a valid index.

Try running this and see if it deletes rows when you enter the SubItem text:

#include <GUIConstantsEx.au3>
#include <EditConstants.au3>
#Include <GuiListView.au3>

$hGUI = GUICreate("Test", 500, 500)

Global $aItems[10][2]

For $i = 0 To 9
    $aItems[$i][0] = "Item " & $i
    $aItems[$i][1] = "SubItem 1" & $i
Next

$hLV = GUICtrlCreateListView("Col 1|Col 2", 10, 10, 200, 300)
$hLV_Handle = GUICtrlGetHandle($hLV)
_GUICtrlListView_SetColumnWidth($hLV, 0, 100)
_GUICtrlListView_SetColumnWidth($hLV, 1, $LVSCW_AUTOSIZE_USEHEADER )

_GUICtrlListView_AddArray($hLV, $aItems)

$hInput = GUICtrlCreateInput("", 10, 400, 200, 20)
GUICtrlSendMsg(-1, $EM_SETCUEBANNER, True, "Enter the text of the item/subitem to delete")

$hButton = GUICtrlCreateButton("Delete", 10, 450, 80, 30)

GUISetState()

While 1

    Switch GUIGetMsg()
        Case $GUI_EVENT_CLOSE
            Exit
        Case $hButton
            $sText = GUICtrlRead($hInput)
            $iIndex = _GUICtrlListView_FindInText($hLV_Handle, $sText)
            _GUICtrlListView_DeleteItem($hLV_Handle, $iIndex)
    EndSwitch

WEnd

If this script works for you then I am running out of ideas as to why your other script does not. :graduated:

Can it have anything to do with that i stored the value as an array?

like this

Dim $aItems[1][6]

For $iI = 0 To UBound($aItems) - 1

$aItems[$iI][0] = $packetcount2[0]

$aItems[$iI][1] = $packetcount2[1]

$aItems[$iI][2] = $packetcount2[2]

$aItems[$iI][3] = "test"

$aItems[$iI][4] = $packetcount2[3]

$aItems[$iI][5] = $hSocket

ConsoleWrite('@@(266) :(' & @MIN & ':' & @SEC & ')' & $allclients[1] & "3: " & $aItems[0][0] & @CR) ;### Function Trace

_GUICtrlListView_AddArray($ListViewClients, $aItems)

$packetcount2 = ""

$aItems = ""
