<SetProperty Id="DBTYPE" Value="2" After="AppSearch">DBVERS</SetProperty>
The condition means "if DBVERS has any value". An empty string is the same as no value and is equivalent to a property that doesn't exist. -----Original Message----- From: Justin Hull [mailto:justin.h...@assetpoint.com] Sent: 09 October 2012 17:01 To: General discussion for Windows Installer XML toolset. Subject: [WiX-users] Setting Property based on condition We have a situation where the original install uses a property named 'DBTYPE' to determine optional nstall of files. On the base install, some properties are written to the registry, but DBTYPE is not. In the patch this is having a negative effect because the DBTYPE is defaulted to '1' and when it was set to '2' in the base install, the patch installs the wrong files. To correct this until we can perform a new full base version we are looking to test the value of another property to set DBTYPE <Property Id="DBVERS"> <RegistrySearch Id="GetRegDbVers" Root="HKLM" Key="SOFTWARE\AssetPoint\[ProductName]" Type="raw" Name="DBVers" /> </Property> <SetProperty Id="DBTYPE" After="AppSearch" Value="????"> In the example, when DBVERS has a value (the value does not matter) we need to set DBTYPE to '2'. I have looked for examples, but cannot find a direct method. I am not certain how a custom action would work here. Is there are way to say IF DBVERS <> "" THEN SET DBTYPE="2" Justin Hull Sr. Developer Maximizing Asset Performance (864) 679-3513 Office ----------------------------------------------------------------------------- - Don't let slow site performance ruin your business.
