Im trying to set background color for a listbox.Is it possible to set background color for a listbox?

Yes, it is. You need following:
- HWND of ListBox
- MSDN -> Name of message to do your task
- Know how to send windows messages. There is a lot of examples in the forum

Well, it isn't as hard as I thought. You need SetCtlColors instruction.
!include nsDialogs.nsh
Name "ListBox Colors"
OutFile "ListBox Colors.exe"
Page custom nsDialogsPage
Var LIST_1
Var LIST_2
Function nsDialogsPage
    nsDialogs::Create /NOUNLOAD 1018
    Pop $0
    ${NSD_CreateListBox} 0 0 150 180 Test
    Pop $LIST_1
    SendMessage $LIST_1 ${LB_ADDSTRING} 0 "STR:Item"
    SendMessage $LIST_1 ${LB_ADDSTRING} 0 "STR:Item"
    SendMessage $LIST_1 ${LB_ADDSTRING} 0 "STR:Item"
    SetCtlColors $LIST_1 0x3333CC 0xFFFFCC
    
    ${NSD_CreateListBox} 160 0 150 180 Test
    Pop $LIST_2
    SendMessage $LIST_2 ${LB_ADDSTRING} 0 "STR:Item"
    SendMessage $LIST_2 ${LB_ADDSTRING} 0 "STR:Item"
    SendMessage $LIST_2 ${LB_ADDSTRING} 0 "STR:Item"
    SetCtlColors $LIST_2 0x990033 0xFFCC33
    nsDialogs::Show

I have used the following code :
GetDlgItem $1 $HWND 1201
SetCtlColors $1 0xFFFFFF 191970

the listbox is created using ini.The color sets upon the selection of the items in the list box.How can i set the color at once instead of selecting individual items?
