Automated-build version number with WiX, Inno Setup, and VS2008

Question

Basically what I need is an automated way to update the product version number in WiX (3.0 with Votive etc), and then get that version number into an Inno Setup "bootstrapper"

I pretty much have the process mostly automated, however version numbers still need to be updated manually which obviously isn't ideal, but I couldn't find how to pass in values to Inno Setup at compile time (and how to reference them), and in the WiX project I need to know how to reference the version number of a different project in the same solution in Visual Studio 2008

No need to pass anything! You can simply let the InnoSetup Preprocessor read the version info straight from the binary's version resource, e.g.:

#define AppName "My App"
#define SrcApp "MyApp.exe"
#define FileVerStr GetFileVersion(SrcApp)
#define StripBuild(str VerStr) Copy(VerStr, 1, RPos(".", VerStr)-1)
#define AppVerStr StripBuild(FileVerStr)

[Setup]
AppName={#AppName}
AppVersion={#AppVerStr}
AppVerName={#AppName} {#AppVerStr}
UninstallDisplayName={#AppName} {#AppVerStr}
VersionInfoVersion={#FileVerStr}
VersionInfoTextVersion={#AppVerStr}
OutputBaseFilename=MyApp-{#FileVerStr}-setup

Before version 5.4.1 (2011-02-09) ISPP was not included in the default InnoSetup package. You had to download the InnoSetup Quick Start Pack: http://www.jrsoftware.org/isdl.php#qsp (thanks @Gwyn, for the update)
