MASM32编程获取Windows当前桌面主题名 -阿里云开发者社区

在网上没有找到现成的代码，只能DIY了。

方法和步骤如下：

1、检查注册表中HKEY_CURRENT_USER/Software/Microsoft/Windows/CurrentVersion/Themes/LastTheme下DisplayName of Modified的值，若其值非空，则为当前主题名；若其值为空，则往下做2。

2、若其值为空，则检查HKEY_CURRENT_USER/Software/Microsoft/Windows/CurrentVersion/ThemeManager下的ThemeActive项，若其值为字符串"0"，则当前使用的是“windows经典”风格；若其值为字符串"1"，则需要往下做3。

3、有两种方法可以获得当前主题对应的文件：

一种方法是继续访问注册表HKEY_CURRENT_USER/Software/Microsoft/Windows/CurrentVersion/Themes/LastTheme下的ThemeFile项的值，其值为当前使用的主题文件名（如：%SystemRoot%/resources/Themes/luna/luna.msstyles）；

若ThemeFile值为空, 则使用HKEY_CURRENT_USER/Software/Microsoft/Windows/CurrentVersion/ThemeManager下DllName项的值作为当前使用的主题文件名。

另一种方法是使用uxtheme.dll中的API函数GetCurrentThemeName()来获取当前主题文件名。

4、主题文件（如%SystemRoot%/resources/Themes/luna/luna.msstyles）对应的具体主题名称一般存放在同名的*.theme文件（如：%SystemRoot%/Resources/Themes/Luna.theme）中。

*.theme文件结构与.INI文件类似，其

[Theme]节中的DisplayName项就是具体主题名称。

如果DisplayName项的值为： “@themeui.dll,-2016”这样的格式，我们可以从HKEY_CURRENT_USER/Software/Microsoft/Windows/ShellNoRoam/MUICache获取该值对应的具体名称，如，"@themeui.dll,-2016"对应的值为"Windows 经典"。

具体代码如下：
