GuiListViewEx error

[Slipk]

Hello everybody,

I download the GUIListViewEx.au3 by Melba23 in order to move up or down my items from a listview.

Everything it's looking good in script but when I move an item it will crash.

Any suggestions?

Thank you!

Slipk,

Please post the code you use (see here how to do it) and an explanation of exactly what you do to get the error- without that how on earth do you expect me to debug?

I understand, the code it's too long to post it here and with too many includes.

I will try to fix and do some testing and come back with details.

I tried absolutely anything I could. Please help me, I can't provide the code as it's too big for that like (100scripts+) with too many includes.

Do you know anything that could cause that error?

 

With a simple script that I created it's working. I tried to put before/after @SW_SHOW , that's some part of code below :

;TOP
#include <GUIListViewEx.au3>

;UP
$Form_Menu_Script = GUICtrlCreateListView("Example|Value 1|Value 2|Value 3|Value 4", 225, 0, $var1, $var2)
GUICtrlSendMsg($ListView1, $LVM_SETCOLUMNWIDTH, 0, 250)
GUICtrlSendMsg($ListView1, $LVM_SETCOLUMNWIDTH, 1, 150)
GUICtrlSendMsg($ListView1, $LVM_SETCOLUMNWIDTH, 2, 150)
GUICtrlSendMsg($ListView1, $LVM_SETCOLUMNWIDTH, 3, 150)
GUICtrlSendMsg($ListView1, $LVM_SETCOLUMNWIDTH, 4, 150)

;THIS BEFORE @SW_SHOW

_GUIListViewEx_Init($ListView1, "", 0, 0, True, 64)
_GUIListViewEx_MsgRegister()

Another thing I want to precise is that I use dynamic listview items, they don't have variable, also they use right click menu. (;GUICtrlCreateContextMenu)

I run as admin, I'm using AutoItSetOption("GuiOnEventMode", 1).

 

Any, at least one suggestion?

Thank you for your help.

PROBLEM SOLVED***

If you create from the GUI the listviewitems you have to reinitialize the UDF Functions.

;example    
   
        Case $Button1
            GUICtrlCreateListViewItem("example", $ListView1)
            _GUIListViewEx_Close()
            _GUIListViewEx_Init($ListView1, "", 0, 0, True, 64)
            _GUIListViewEx_MsgRegister()

Slipk,

The UDF uses its own internal array to hold and manipulate the ListView data - one way to get an error like that is to add/subtract items from the ListView other than by using the UDF functions, which causes a mismatch between the displayed control and the internal array. Could that be the problem?

I am afraid that I cannot offer more than that SWAG* without some working code that demonstrates the error.

Slipk,

I see you found the solution - which is explained in the "User Guide" document in the UDF zip:

Quote

Closure and Reloading:

If you delete the ListView, then it is recommended to use _GUIListViewEx_Close to free the memory used by the UDF.

If you wish to reload the ListView with new data, you will need to clear the current content using _GUICtrlListView_DeleteAllItems, close it within the UDF using _GUIListViewEx_Close, reload the ListView with the new data and then reinitialise it using _GUIListViewEx_Init. Otherwise the UDF will become confused about the current content and errors will certainly occur.

Edit; And my SWAG was correct!
