[wix-users] Passing value from bundle.wsx to bootstrapper code

[Jon Earle]

Okay, both of those were needed, as you suggested. I never realized you needed the wrapper around the variable, but it makes sense now, to evaluate the variable content as a property.


<Variable Name="INSTALLDIR" bal:Overridable="yes" Value="[$(var.PlatformProgramFilesFolder)]Company\Client"/>


And the FormatString wrapper.  Why do I need to use that - only to evaluate the property?

Bootstrapper.Engine.FormatString ?

And you need to include the []'s in your definition.

In my bundle.wxs:


<Variable Name="INSTALLDIR" bal:Overridable="yes" Value="C:\Program Files\Company\Client"/>


My cs code:


string userSpecifiedInstallDir = Bootstrapper.Engine.StringVariables["INSTALLDIR"];


No problem - I get the value, I can modify it, etc.


Now, If I try to be clever and use some of the builtin vars, such as in the following:


<Variable Name="INSTALLDIR" bal:Overridable="yes" Value="[ProgramFiles64Folder]"/>


I get the literal text "[ProgramFiles64Folder]" and not what it translates to.  How do I fix that?


Now, I actually want to get more clever and:


    <?if $(var.Platform) = x64 ?>
        <?define PlatformProgramFilesFolder = "ProgramFiles64Folder" ?>
    <?else ?>
        <?define PlatformProgramFilesFolder = "ProgramFilesFolder" ?>
    <?endif ?>

So that I can be flexible.
I tried to use:


<Variable Name="INSTALLDIR" bal:Overridable="yes" Value="$(var.PlatformProgramFilesFolder )"/>


But that only gave me the literal text "ProgramFiles64Folder". I don't quite understand why, since, in my product.wxs, I have:


        <Directory Id='TARGETDIR' Name='SourceDir'>
            <Directory Id="$(var.PlatformProgramFilesFolder)">
                <Directory Id='MANUFACTURER' Name="Company">
                    <Directory Id='INSTALLDIR' Name="Client" />
                </Directory>
            </Directory>
        </Directory>


And that works fine.  What am I missing?


Cheers!

Jon
