You have to pass properties to deferred CAs in a particular way. Effectively, you concatenate their string values together, with some unique separator, into a property with the same name as your custom action. In the CA you read that property and parse the values back out. Again there are some wix SDK functions to make this simpler but it's not too tricky to do yourself either. The limitations and process are described here http://msdn.microsoft.com/en-us/library/windows/desktop/aa370543%28v=vs.85%29 .aspx
The choice between immediate and deferred should be based on whether the action changes the system. Deferred actions run as the system, not as the installing user. I'd recommend reading this section http://msdn.microsoft.com/en-us/library/windows/desktop/aa368268%28v=vs.85%29 .aspx -----Original Message----- From: Natalie Carr [mailto:natalie.c...@measuresoft.com] Sent: 17 October 2012 11:40 To: 'General discussion for Windows Installer XML toolset.' Subject: Re: [WiX-users] Adding ticks to immediate custom actions Thanks Peter, I get 4 properties from my MSI in my custom action so that is why it is immediate. Am I correct in thinking you cannot get properties in deferred custom actions? -----Original Message----- From: Peter Shirtcliffe [mailto:pshirtcli...@sdl.com] Sent: 17 October 2012 11:27 To: General discussion for Windows Installer XML toolset. Subject: Re: [WiX-users] Adding ticks to immediate custom actions You ultimately have to call MsiProcessMessage. The Wix SDK might have some useful functions to make that easier. Scheduling a deferred CA with WcaDoDeferredAction from the Wix SDK is easy because it allows you to specify the ticks as its 3rd parameter. There might be an equivalent for immediate actions. Have a read of the code for WcaDoDeferredAction in the wix sources in wcawrap.cpp if there isn't. -----Original Message----- From: Natalie Carr [mailto:natalie.c...@measuresoft.com] Sent: 17 October 2012 10:42 To: wix-users@lists.sourceforge.net Subject: [WiX-users] Adding ticks to immediate custom actions I have a few custom actions that run just before InstallFinalize and I am trying to tidy up my progress bar because at the moment it runs two or three times and looks empty just before the install completes. They are immediate custom actions and I have used ProgressText to show text explaining what they do for the user but I would like to know how to give them ticks so that they are displayed correctly in the progress bar. Can anyone help me please? Kind Regards, Natalie Carr ---------------------------------------------------------------------------- - - Everyone hates slow websites. So do we.
