NSIS ListView - GetItemText returns 错误值

Question

我尝试使用 ListView 创建 Windows 安装程序。我能够将项目插入列表视图：

# put the plugin version to list view (in my case value 2.2)
${NSD_LV_InsertItem} $list $i ''

然而，当我尝试从给定索引读取值时：

# get selected item plugin version
${NSD_LV_GetItemText} $list 0 0 $R0
MessageBox MB_OK "The text of item 0 is: $R0"

我收到消息：第 0 项的文本是：▯2
为什么输出显示不正确？

谢谢！

Answer 1

"▯2" 是被视为 UTF-16LE 字符串的 "2.2" ASCII 字符串。

第 3 方 CommCtrl.nsh 文件存在错误，您需要确保 LVM_* 定义对于您的目标是正确的。

!include nsDialogs.nsh
!include WinMessages.nsh ; The 3rd-party CommCtrl.nsh file is buggy, include this first to make sure LVM_* is defined correctly
!ifndef LVM_GETITEMTEXT
!define /math LVM_GETITEMTEXTA ${LVM_FIRST} + 45
!define /math LVM_GETITEMTEXTW ${LVM_FIRST} + 115
${_NSIS_DEFAW} LVM_GETITEMTEXT
!endif
!include "CommCtrl.nsh"
!define /ifndef _COMMCTRL_NSH_VERBOSE ${_COMMCTRL_VERBOSE}
