Wix Installer - Create Folder hierarchy based on Property

Question

I am using Wix 3.6 to create a setup. I am still learning as I go along. The information out there is still scattered around. I am just waiting for my Wix Developer Guide book arriving.

I currently have a custom UI dialog where the user enters some application configuration. Part of that configuration is to specify a log folder. This at present this just sets a property [LogFolder]. This is defaulted to something like D:\Logs.

I want the installer to create that directory when the setup is run. I have the following to try and do this but it just created a folder named [LOGFOLDER] on the D: drive when I run the setup.

<Product ...
    <Directory Id="TARGETDIR" Name="SourceDir" >
        <Directory Id="LogFolderDir" Name="[LOGFOLDER]" >
            <Component Id="LogFolderComponent" Guid="{7E7D6916-B321-40D6-ABAD-696B57A6E5FB}" KeyPath="yes">
                <CreateFolder />
            </Component>
        </Directory>
    </Directory>
    ...
</Product>

How can I do this with Wix?

Answer 1

第一步是创建一个属性设置为您想要的值：

<Product>
  <Property Id="LOGFOLDER" Value="D:\Logs" />
</Product>

第二步是创建一个对话框，您可以在其中设置此属性（或其他更改其值的内容）：

<Dialog>
  <Control Id="Edit_LogFolder" Type="Edit" Property="LOGFOLDER" />
</Dialog>

然后您需要更改目录结构以在默认位置创建此文件夹：

<Directory Id="ProgramFilesFolder">
  <Directory Id="INSTALLFOLDER" Name="MyApp">

    <Directory Id="LOGFOLDER" Name="Logs" />

  </Directory>
</Directory>

最后一步是创建一个将创建目录的组件，如下所示：

<ComponentGroup Id="ComponentGroup_LogFolder">
  <Component Id="Component_LogFolder" Guid="" Directory="LOGFOLDER">

    <CreateFolder Directory="LOGFOLDER" />

  </Component>
</ComponentGroup>

如果 D:\ 是磁盘驱动器并且您插入了磁盘，则安装将失败，因为它会尝试创建文件夹并且不会成功。
