Project • This information applies to InstallScript MSI projects.
The OnFilesInUse event handler is called in an InstallScript MSI installation when the Windows Installer sends an INSTALLMESSAGE_FILESINUSE message to the installation.
The szMessage parameter contains the string that the Windows Installer provides. This parameter indicates the files that are in use. The SdFilesInUse function parses this string appropriately.
By default, the OnFilesInUse event handler displays the SdFilesInUse dialog. The event handler returns the value that the dialog returns, and the value is then passed back to the Windows Installer to indicate how the message was handled and what action the Windows Installer should take.
