IMsmMerge interface (mergemod.h)

The IMsmMerge interface and the IMsmMerge2 interface provide interfaces to the Merge object. The Merge object provides access to other top-level objects. A Merge object must be created before loading the automation support required by COM to access the functions in Mergemod.dll.

Inheritance

The IMsmMerge interface inherits from the IDispatch interface. IMsmMerge also has these types of members:

Methods

The IMsmMerge interface has these methods.

IMsmMerge::CloseDatabase The CloseDatabase method closes the currently open Windows Installer database. For more information, see the CloseDatabase method of the Merge object.
IMsmMerge::CloseLog The CloseLog function method closes the current log. For more information, see the CloseLog method of the Merge object.
IMsmMerge::CloseModule The CloseModule method closes the currently open Windows Installer merge module. For more information, see the CloseModule method of the Merge object.
IMsmMerge::Connect The Connect method connects a module that has been, or will be, merged into the database to an additional feature. For more information, see the Connect method of the Merge object.
IMsmMerge::ExtractCAB The ExtractCAB method extracts the embedded .cab file from a module and saves it as the specified file.
IMsmMerge::ExtractFiles The ExtractFiles method extracts the embedded .cab file from a module and then writes those files to the destination directory. For more information, see the ExtractFiles method of the Merge object.
IMsmMerge::get_Dependencies The get_Dependencies method retrieves the Dependencies property of the Merge object.
IMsmMerge::get_Errors The get_Errors method retrieves the Errors property of the Merge object. This retrieves the current collection of errors.
IMsmMerge::Log The Log method writes a text string to the currently open log file. For more information, see the Log method of the Merge object.
IMsmMerge::Merge The Merge method executes a merge of the current database and current module.
IMsmMerge::OpenDatabase The OpenDatabase method opens a Windows Installer installation database, located at a specified path, that is to be merged with a module. For more information, see the OpenDatabase method of the Merge object.
IMsmMerge::OpenLog The OpenLog method opens a log file that receives progress and error messages.
IMsmMerge::OpenModule The OpenModule method opens a Windows Installer merge module in read-only mode. A module must be opened before it can be merged with an installation database. For more information, see the OpenModule method of the Merge object.
