When you build, you have access to the file you will be adding to the MSI for installation. That file must exist at least before you call light.exe when it gets bound, but depending on your build environment it will likely be ready before you even call candle.exe. What I suggest is to read that file during your build, extracting out whatever you need for your installation, and populating your MSI with that information (could be via preprocessor variables or even possibly linker variables depending on where and how you are consuming that information.
Even if you are replacing that file in your MSI post-linking, you can read the file and alter the data in the database accordingly when you are changing the file data in the database. Salever.lee, he needs to read an INI file he is installing. The support WiX/Windows Installer has for that requires the INI file to exist/be accessible before the installation starts. -----Original Message----- From: salever.lee [mailto:salever....@gmail.com] Sent: Thursday, November 12, 2009 5:47 PM To: General discussion for Windows Installer XML toolset. Subject: Re: [WiX-users] How to read a file to a property Hi, You can try to use *.ini files instead of *.txt files. As I known, Wix has its way to deal with ini files, See Wix tutorial. Good luck. 2009-11-13 salever.lee 发件人： HuangRunzhen 发送时间： 2009-11-13 05:16:57 收件人： wix-users@lists.sourceforge.net 抄送： 主题： Re: [WiX-users] How to read a file to a property Thanks. I do need data from a file I am installing. Could you explain in more detail "how to read from the file while building and populate your property that way"? Do you mean I read the file from machine and put into a property and use it in CA? If I use a deferred CA, can I change the registry directly by calling WinAPI?
