Wix, Heat and Wxi File

Question

I use heat.exe to generate a list of files, I need to replace File / @ Source = "SourceDir" so I pass the name -var and the name of the directory, but these variables are defined in my .wxi file How to include a .wxi file in a heat generated file wxs . since this file will be generated every time I make an assembly.

Answer 1

Why replace SourceDir?

You can simply transfer additional base folders for highlighting using the switch -band for all SourceDir links, WiX will search in the base folders you specify. It's easy to move things between machines and update a parameter in your build system, rather than edit an include file.

Answer 2

wix 3.7, HeatDirectory wixproj heat.exe, PreprocessorVariable SourceDir.

<Target Name="BeforeBuild">
<HeatDirectory Directory="..\distribution"
               PreprocessorVariable="myVar"  <--- your variable name
               OutputFile="HeatGeneratedFileList.wxs"
               ComponentGroupName="HeatGenerated"
               DirectoryRefId="INSTALLFOLDER"
               AutogenerateGuids="true"
               ToolPath="$(WixToolPath)"
               SuppressFragments="true"
               SuppressRegistry="true"/>
</Target>
