Question

我想安装在我的安装程序中：

安装期间无限音乐循环播放
背景窗口（就像过去用屏幕填充图像并只显示安装窗口的旧安装），在该背景窗口上放置幻灯片

如何在InnoSetup中执行此操作？

Answer 1

如果您希望安装程序的背景图片幻灯片显示无限音乐播放，您可以执行以下操作：以下内容：

获取最新版本的InnoCallback库以进行幻灯片计时器实现
用于音乐播放，例如Unicode Inno Setup

Inno Media Player

编写类似于以下的脚本，或download the complete project，其中包括下一个脚本代码中使用的所有必要文件。因此，您唯一需要做的就是在最新版本的Unicode Inno Setup中构建它。

请注意，Inno Media Player是一个Unicode库，因此您只能使用Inno Setup的Unicode版本，而不能使用ANSI版本！不支持ANSI版本的Inno Setup ...！

创建背景功能：

您是否尝试过图形安装程序（http://www.graphical-installer.com）？

这是一个专门为此设置的Inno Setup扩展（创建具有背景的酷炫安装程序），因此创建这样的安装程序只需几分钟（无需编码）。
