There are two codepages in an MSI database: the database codepage, and the summary info codepage. They can be different, and there are circumstances where the valid values for each are different as well.
The functions that Phil mentions retrieve the summary info codepage, not the database codepage. See http://msdn.microsoft.com/library/aa367864.aspx. Microsoft didn't document anywhere I have found yet where/how they encode the database codepage within the MSI file. Nor does it appear that they supplied an API to retrieve it. Why do you need it? The "Unicode" APIs will always return the strings in 16-bit Unicode, and the "ANSI" APIs will always convert strings to the thread's current codepage (as best as it can). -----Original Message----- From: Wilson, Phil [mailto:phil.wil...@invensys.com] Sent: Friday, May 28, 2010 9:48 AM To: General discussion for Windows Installer XML toolset.

Unless I'm missing something, that's MsiGetSummaryInformation() and MsiGetSummaryInfoGetProperty() and associated Win32 functions, or the scripting Installer.SummaryInfo etc Phil Wilson -----Original Message----- From: Yan Sklyarenko [mailto:y...@sitecore.net] Sent: Friday, May 28, 2010 2:13 AM To: General discussion for Windows Installer XML toolset. Subject: [WiX-users] How to detect MSI database codepage at runtime? Hi WiX Community, Does anyone know if it is at all possible to get the MSI database codepage at runtime? The session.Database.CodePage throws exception... The MSDN says you should export tables (wtf???) in order to determine the codepage - that's probably why session.Database.CodePage fails from CA... But when language transform is applied, it changes the code page somehow, right? And it is at runtime, so there must be an option to get it at runtime as well... Any ideas?
