Return value
IList<System.String> An array of selected patch strings from patches , indicating the set of applicable patches. The items are re-ordered to be in the best sequence.
Remarks
If an item in patches is a file path but does not end in .MSP or .XML, it is assumed to be an MSP file.

Session A Session object allowing access to the product database and install engine
Remarks
Note that only one Session object can be opened by a single process. OpenPackage cannot be used in a custom action because the active installation is the only session allowed. A "safe" Session object ignores the current computer state when opening the package and prevents changes to the current computer state. The Session object should be «see M:WixToolset.Dtf.WindowsInstaller.InstallerHandle.Close» d after use. It is best that the handle be closed manually as soon as it is no longer needed, as leaving lots of unused handles open can degrade performance. Win32 MSI APIs: MsiOpenPackage , MsiOpenPackageEx
Exceptions
| Exception | Description |
|---|---|
| T:WixToolset.Dtf.WindowsInstaller.InstallerException | The product could not be opened |
| T:WixToolset.Dtf.WindowsInstaller.InstallerException | The installer configuration data is corrupt |

SetExternalUI(uiHandler, messageFilter) Method
Enables an external user-interface handler. This external UI handler is called before the normal internal user-interface handler. The external UI handler has the option to suppress the internal UI by returning a non-zero value to indicate that it has handled the messages.
Declaration
public static ExternalUIHandler SetExternalUI(
ExternalUIHandler uiHandler,
InstallLogModes messageFilter
)
Parameters
| Parameter | Type | Description |
|---|---|---|
| uiHandler | ExternalUIHandler | A callback delegate that handles the UI messages |
| messageFilter | InstallLogModes | Specifies which messages to handle using the external message handler. If the external handler returns a non-zero result, then that message will not be sent to the UI, instead the message will be logged if logging has been enabled. |
Return value
ExternalUIHandler The previously set external handler, or null if there was no previously set handler
Remarks
To restore the previous UI handler, a second call is made to SetExternalUI using the ExternalUIHandler returned by the first call to SetExternalUI and specifying «see F:WixToolset.Dtf.WindowsInstaller.InstallLogModes.None» as the message filter. The external user interface handler does not have full control over the external user interface unless «see M:WixToolset.Dtf.WindowsInstaller.Installer.SetInternalUI(WixToolset.Dtf.WindowsInstaller.InstallUIOptions)» is called with the uiLevel parameter set to «see F:WixToolset.Dtf.WindowsInstaller.InstallUIOptions.Silent» . If SetInternalUI is not called, the internal user interface level defaults to «see F:WixToolset.Dtf.WindowsInstaller.InstallUIOptions.Basic» . As a result, any message not handled by the external user interface handler is handled by Windows Installer. The initial "Preparing to install..." dialog always appears even if the external user interface handler handles all messages. SetExternalUI should only be called from a bootstrapping application. You cannot call it from a custom action Win32 MSI API: MsiSetExternalUI
