There are different layers of variables in WiX (candle's preprocessor variables, Light's WixVariables/localization variables/binder variables, and MSI's properties). Each have different syntax and are evaluated at different times:
Candle's preprocessor variables "$(var.VariableName)" are evaluated when candle runs, and can be set from candle's commandline and from "<?define VariableName=value?>" statements. Buildtime environment properties as well as custom variables can also be accessed similarly (changing the "var." prefix with other values). Light's variables accessible from the command-line are the WixVariables, and accessing them is via the "!(wix.VariableName)" syntax. To access your variable from your commandline, you would need to change your String to: <String Id="WelcomeDlgDescription3" Overridable="yes">This build was prepared on !(wix.BuildMachine)</String> If you instead need to have the BuildMachine value exist as an MSI property at installation time (which is the "[VariableName]" syntax) you would need to add the following to one of your wxs files in a fragment that is already linked in: <Property Id="BuildMachine" Value="!(wix.BuildMachine)"/> Now, the environment variable COMPUTERNAME always has held the name of my build machines in the past, and you can access that this way: $(env.COMPUTERNAME). So, you can get rid of the commandline addition to light.exe and change your wxs file like this: <WixProperty Id="BuildMachine" Value="$(env.COMPUTERNAME)"/> -Blair -----Original Message----- From: Graeme English [mailto:graeme.engl...@hotmail.co.uk] Sent: Monday, September 14, 2009 1:13 AM To: wix-users@lists.sourceforge.net Subject: [WiX-users] Access to variables in localization strings I'm trying to replace a variable within a localization string however it always appears blank. I've been using Light -dBuildMachine=abc. Anyone know if this should work? e.g. <WixLocalization Culture="en-us" xmlns="http://schemas.microsoft.com/wix/2006/localization";> <String Id="WelcomeDlgDescription3" Overridable="yes">This build was prepared on [BuildMachine]</String> Cheers, Graeme ---------------------------------------------------------------------------- -- Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.
