How to populate a ComboBox?

How can I add items to a combobox? I need to create a combobox in a custom page, that the user can use to select his language. Then I need to pass this info to a Section to make different operations for different languages.

Use the CB_ADDSTRING message if you are using nsDialogs.

Edit:
${NSD_CB_AddString}

Good! ..and now how can I know what item is selected? I need to know what language the user have selected and set the language name as a string variable, to use it during the extraction process.

CB_GETCURSEL:
http://msdn.microsoft.com/en-us/library/bb775845(VS.85).aspx

SendMessage <hwnd> ${CB_GETCURSEL} 0 0 $0

$0 will contain selected index (0-based, so first item is zero, 2nd item is one, etc.)

!include "winmessages.nsh"

!include "LogicLib.nsh"

!include "nsDialogs.nsh"



Outfile "test.exe"



var dialog

var hwnd

var null



Page custom customPageA



Function customPageA



	nsDialogs::Create 1018

	Pop $dialog



	${NSD_CreateCombobox} 0 0 100% 100% ""

		Pop $hwnd

		${NSD_CB_ADDSTRING} $hwnd "Hello"

		${NSD_CB_ADDSTRING} $hwnd "World"

		${NSD_OnChange} $hwnd combobox.onchange

	nsDialogs::Show

	Abort

FunctionEnd



Function combobox.onchange

	Pop $hwnd

	SendMessage $hwnd ${CB_GETCURSEL} 0 0 $0

	MessageBox MB_OK "[$0]"

FunctionEnd



Section ""

SectionEnd

Thanks!
