Question

I’m using the msbuild heat wrapper to generate the component list for my website installer, and trying to figure out how to define permissions on a folder deep in that tree.

In my generated wxs file I’ve got

<Directory Id="dirC092054A3A348CC48B696FD466A89A2F" Name="ExportFiles">
<Component Id="cmp699347B0054EDD7DD7B0935D39A66FAE" Guid="{5037..}">
  <File Id="..." KeyPath="yes" Source="SourceDir\Reports\ExportFiles\donotdelete.txt" />
</Component>
</Directory>

And I realise I could use a CreateFolder and Permission element here, but this file is regenerated on the prebuild so I’d loose my changes each time. Is there a was of setting the permission on the ExportFiles folder from within my main Product.wxs file?

Answer 1

Create a custom action and then set the permission on the folder. Use this code

string directory = session["PATH"] + "Temp";
if (Directory.Exists(directory))
{
    DirectoryInfo dInfo = new DirectoryInfo(directory);
    DirectorySecurity dSecurity = dInfo.GetAccessControl();
    dSecurity.AddAccessRule(new FileSystemAccessRule("Everyone", FileSystemRights.FullControl,
            InheritanceFlags.ContainerInherit | InheritanceFlags.ObjectInherit, PropagationFlags.None,
            AccessControlType.Allow));
    dInfo.SetAccessControl(dSecurity);
}

This code will make the folder shared to everyone.
