I have problem with _GUICtrlListViewInsertItem

[lsakizada]

Hi, I am inserting xml into listview item:

_GUICtrlListViewInsertItem($lst_result,0,$URL)

where :

$URL is the xml (I count 1612 characters) ,

0 - input into first line

$lst_result is the listview control

The problem that the xml string is truncated and not entered well.

Is it a problem of the Method or the buffer of the list item is to small.

If it too smal, then how to increase it.

My guess is Microsoft limitation, the insert uses StringLen($s_text) + 1 for the length of the insert.

did some testing, so now my guess would be your code, or the string your trying to insert is the problem

below is the test of 1700 characters, works just fine.

Yes your code is working.

I think the problem is because the XML file that was input on one item contain

a special character that cause the problem.

Hi,

But item "0"only has 255 chars[by looking at the listview itself; ]? [GetText incorrect!; and length];

For $x = 1 To 1700
    $test &= chr (mod($x,52)+64)
Next

What can be displayed and what is actually is stored is two different things

Note that although the list-view control allows any length string to be stored as item text, only the first 260 TCHARs are displayed.
