invite all budlist in c++

VB6 or VB.NET version do as follow:

Set up our local LV_ITEM to change the selected item = LVIF_STATE

LVITEM.state = LVIS_CHECKED
LVITEM.stateMask = LVIS_STATEIMAGEMASK

The rest you know what to do

where i is totalPals
for i as integer = 0 to totalPals - 1
SendMessage(hwnd, LVM_SETITEMSTATE, i, LVI)
next i

hope this helps.

nvye can you tell me how to declare these variables ?

LVITEM.mask = LVIF_STATE
LVITEM.state = LVIS_CHECKED
LVITEM.stateMask = LVIS_STATEIMAGEMASK

You can find everything here:
As for LVIS_CHECKED, there is no such thing. Image state is one-based image-index that is application dependent value that is represented by bits 12-15. That is (index shift left 12)
As you can see in BattleStar-Galactica’s code it’s 2 << 12 = 8192 decimal or 2000 hex.

Good heavens method, it’s all there. Those are hexdecimal integer constants, just replace 0x with &H

Thanks guys i tried the following code but paltalk keep closing when i click the button. Could you you guys tell what i am doing wrong and how to fix it ?
