Hi,

In a VBScript Custom Action, you can simply use the WriteToLog function described in this HowTo article:

Code: Select all

Function WriteToLog(msg)
  Const msiMessageTypeInfo = &H04000000
  Set record = Session.Installer.CreateRecord(1)
  record.StringData(0) = "[1]"
  record.StringData(1) = CStr(msg)
  Session.Message msiMessageTypeInfo, record
End Function

You can invoke it from your code as follows:

Code: Select all

Function YourCAFunction
  WriteToLog("[MY_CA] Message for log.")
End Function

Keep in mind however that your Custom Action must be scheduled in one of sequence tables (InstallUISequence and/or InstallExecuteSequence) - logging will not work from an UI Custom Action.

In a C++ DLL Custom Action use the MsiProcessMessage function.
