SprintfMsiLog doesn't write anything !?

[ChristopheOce]

Hi,

I work with installshield 2008 (basic msi project)
i'd like to place some information in my custom action (install script code) and on internet i've found this link :

http://www.macrovision.com/webdocuments/PDF/msi_writing_to_the_log_file.pdf?link_id=productsTipsTricks

on my project i have a custom action (installscript) who is execute in the user interface when a user click on next :

     ****** other code **********
     SprintfMsiLog("custom action executee !");

but if i launch my file msi in a command prompt with this parameter : /l*v c:\log.txt i can't see anything in the log file about => custom action executee !!!

Have you got any idea what happens ?

Thanks
Christophe

I'm sorry but i think it was an error than me ! !

now i've place the custom action in the sequence as the sample => launch condition and on the log file i can see my sentence !

sorry
Christophe

To write to the MSI log, SprintfMsiLog uses the MsiProcessMessage API. This API does not work from custom actions launched through DoAction events. More information can be found in the following MSDN Windows Installer chat transcript:
