为什么INSTALLFOLDER属性没有通过RadioButtonGroup更改？

Question

WiX。我写的插件必须安装到三个目录中的一个。因此，我创建的自定义对话框，并将其插入到链：

这是我此对话框的代码：

<?xml version='1.0' encoding='Windows-1252'?> 
<!-- SelectInstallDirectory.wxs 
     © Andrey Bushman, 2016 
     Dialog window for the install directory selection of AutoCAD extension. --> 
<Wix xmlns="http://schemas.microsoft.com/wix/2006/wi"> 
    <Fragment> 

    <UI> 
     <!--<Property Id="DefaultUIFont">DlgFont10</Property>--> 
     <TextStyle Id="DlgFont10" FaceName="Tahoma" Size="10" /> 
     <TextStyle Id="DlgFont20" FaceName="Tahoma" Size="20" /> 
     <TextStyle Id="DlgFont10_important" FaceName="Tahoma" Size="10" Red="255" Green="0" Blue="0"/> 
     <TextStyle Id="DlgTitleFont" FaceName="Tahoma" Size="10" Bold="yes" /> 

     <!-- I am forced to define the INSTALLFOLDER again because SelectInstallDirectory dialog 
     doesnt see this property. --> 
     <Property Id="INSTALLFOLDER" Value="$(env.ProgramData)\Autodesk\ApplicationPlugins\ProxyTools.bundle\"/> 

     <!--This dialog selects the install directory through the RadioButton items.--> 
     <Dialog Id="SelectInstallDirectory" Title="AutoCAD extension location" 
       NoMinimize="yes" Width="400" Height="270"> 

     <Control Id="TitleImage" Type="Bitmap" X="0" Y="0" Width="400" Height="65" Text="TitleImageFile"> 
      <Binary Id="TitleImageFile" SourceFile="SelectInstallDirectory_banner.jpg"/> 
     </Control> 

     <Control Id="TitleText" Type="Text" X="60" Y="20" Width="400" Height="35" 
       Transparent="yes" NoPrefix="yes"> 
      <Text>{\DlgFont20}Proxy Tools for AutoCAD</Text> 
     </Control> 

     <Control Id="Title" Type="Text" X="5" Y="85" Width="300" Height="15" 
       Transparent="yes" NoPrefix="yes"> 
      <Text>Select the target directory for the AutoCAD extension installing:</Text> 
     </Control> 

     <Control Id="rbgrPath" Type ="RadioButtonGroup" 
       X="5" Y="100" Width="500" Height="100" Property="INSTALLFOLDER"> 
      <RadioButtonGroup Property="INSTALLFOLDER"> 
      <RadioButton 
       Text="[ProgramFilesFolder]Autodesk\ApplicationPlugins\ProxyTools.bundle\" 
       Value="[ProgramFilesFolder]Autodesk\ApplicationPlugins\ProxyTools.bundle\" 
       Height="13" Width="500" X="5" Y="5"/> 
      <RadioButton 
       Text="$(env.ProgramData)\Autodesk\ApplicationPlugins\ProxyTools.bundle\" 
       Value="$(env.ProgramData)\Autodesk\ApplicationPlugins\ProxyTools.bundle\" 
       Height="13" Width="500" X="5" Y="20"/> 
      <RadioButton 
       Text="$(env.AppData)\Autodesk\ApplicationPlugins\ProxyTools.bundle\" 
       Value="$(env.AppData)\Autodesk\ApplicationPlugins\ProxyTools.bundle\" 
       Height="13" Width="500" X="5" Y="35"/> 
      </RadioButtonGroup> 
     </Control> 

     <Control Id="warning_acad2012" Type="Text" X="5" Y="175" Width="100" Height="30" 
       Transparent="yes" NoPrefix="yes"> 
      <Text>{\DlgTitleFont}WARNING</Text> 
     </Control> 

     <Control Id="warning_acad2012_text" Type="Text" X="10" Y="190" Width="380" Height="40" 
       Transparent="yes" NoPrefix="yes"> 
      <Text>{\DlgFont10_important}Don't select the "$(env.ProgramData)\Autodesk\ApplicationPlugins\ProxyTools.bundle\" variant if you will use AutoCAD 2012, because its bundle-autoloader don't monitor of that directory.</Text> 
     </Control> 

     <Control Id="Back" Type="PushButton" X="205" Y="243" Width="70" 
       Height="17" Default="no" Text="&lt;&lt; Previous"> 
      <Publish Event="NewDialog" Value="LicenseAgreementDlg">1</Publish> 
     </Control> 

     <Control Id="Install" Type="PushButton" X="280" Y="243" Width="56" 
       Height="17" Default="yes" Text="Install"> 
      <Publish Event="NewDialog" Value="SetupTypeDlg">INSTALLFOLDER</Publish> 
     </Control> 

     <Control Id="Cancel" Type="PushButton" X="340" Y="243" Width="56" Height="17" 
       Default="no" Text="Cancel"> 
      <Publish Event="SpawnDialog" Value="CancelDlg">1</Publish> 
     </Control> 
     </Dialog> 
    </UI> 
    </Fragment> 
</Wix> 

注重我在SelectInstallDirectory.wxs文件再次定义的INSTALLFOLDER目录，因为我的对话框在其他文件中定义时看不到INSTALLFOLDER属性（如下所示）。它是否正确？

<Directory Id="TARGETDIR" Name="SourceDir"> 
    <Directory Id="$(var.ADSK_LOCATION)"> 
    <Directory Id="Adsk" Name="Autodesk"> 
     <Directory Id="Adsk_Plugins" Name="ApplicationPlugins"> 
     <Directory Id="INSTALLFOLDER" Name="$(var.EXTENSION_FOLDER_NAME)"> 
      <Directory Id="LICENSE" Name="license"/> 
      <Directory Id="RESOURCES" Name="resources"/> 
      <Directory Id="HELP" Name="help"/> 
      <Directory Id="MENU" Name="menu"> 
      <Directory Id="CUI" Name="cui"/> 
      <Directory Id="CUIX" Name="cuix"/> 
      </Directory> 
      <Directory Id="BIN" Name="bin"> 
      <Directory Id="BIN_RU" Name="ru"/> 
      </Directory> 
     </Directory> 
     </Directory> 
    </Directory> 
    </Directory> 

进入Product元素添加此：

<UI Id="MyWixUI_Mondo"> 
    <UIRef Id="WixUI_Mondo" /> 
    <UIRef Id="WixUI_ErrorProgressText" /> 

    <!-- My dialog for the INSTALLFOLDER value getting. --> 
    <DialogRef Id="SelectInstallDirectory" /> 

    <Publish Dialog="LicenseAgreementDlg" Control="Next" Event="NewDialog" Value="SelectInstallDirectory" Order="3">LicenseAccepted = "1"</Publish> 
    <Publish Dialog="SetupTypeDlg" Control="Back" Event="NewDialog" Value="SelectInstallDirectory">1</Publish> 
</UI> 

现在存在于链我的自定义对话框。但是，如果我在对话窗口中选择了其他目标目录的变体，那么INSTALLFOLDER的值实际上不会改变。我的根Feature元素使用其变量值的ConfigurableDirectory属性（我用这个属性仅用于调试这个插件）：

<Feature Id="$(var.SolutionName)" Title="$(var.ProductName)" Description="The complete package." Display='expand' 
      Level="1" ConfigurableDirectory="INSTALLFOLDER" AllowAdvertise='no' InstallDefault='local' Absent='disallow' 
      TypicalDefault='install'> 

我怎样才能解决呢？

Answer 1

核心问题是，在显示对话框的时候，通过设置属性来更改目录已经太晚了。相反，你必须拨打电话MsiSetTargetPath。通常，通过对话框完成此操作的最佳方式是使用SetTargetPath Control Event。在您的项目中，这可能如下所示：

: : : 
<Control Id="Install" Type="PushButton" X="280" Y="243" Width="56" 
      Height="17" Default="yes" Text="Install"> 
    <Publish Event="SetTargetPath" Value="INSTALLFOLDER">1</Publish> 
    <Publish Event="NewDialog" Value="SetupTypeDlg">INSTALLFOLDER</Publish> 
</Control> 
: : : 

为什么设置属性有时会起作用？因为成本核算通常会根据初始属性执行一系列目录计算，并在内部执行大量设置目标路径。因此，在CostFinalize操作之前，您可以（并且必须）只设置属性。在CostFinalize之后，您必须更直接地调用MsiSetTargetPath。
