The MsiEmbeddedUI table defines a user interface embedded in the Windows Installer package.

Windows Installer 4.0 or earlier:  Not supported. This table is available beginning with Windows Installer 4.5.

The MsiEmbeddedUI table has the following columns.

Columns

MsiEmbeddedUI

The primary key for the table.

FileName

The name of the file that receives the binary information in the Data column. Specify a short and long file name using the Filename format.

Attributes

Information about the data in the Data column. The value in this field can contain one or more of the following constants.

Constant	Hexadecimal	Decimal	Meaning
None	0x00	0	The file is not the DLL file for the user interface. It may be a resource file used by the user interface.
msidbEmbeddedUI	0x01	1	The primary DLL file for the user interface. No more than one row in the table can be marked with this attribute. If multiple rows are marked with this attribute, it is an error and it cannot be guaranteed which DLL is used.
msidbEmbeddedHandlesBasic	0x02	2	Enables the installer to invoke the embedded UI during a basic UI level installation. The installer ignores this attribute if it is not combined with the msidbEmbeddedUI attribute.

MessageFilter

Specifies the types of messages that are sent to the user interface DLL. This column is only relevant for rows with the msidbEmbeddedUI attribute. This field should be null if a row references a resource file and the value of Attributes is null. If a row references a user interface DLL, the value in this column should not be null.

The value in this column can be a combination of the following values. The installer ignores any other values.

Constant	Hexadecimal	Decimal	Description
INSTALLLOGMODE_FATALEXIT	0x00001	1	Premature termination.
INSTALLLOGMODE_ERROR	0x00002	2	Error messages.
INSTALLLOGMODE_WARNING	0x00004	4	Warning messages.
INSTALLLOGMODE_USER	0x00008	8	User messages.
INSTALLLOGMODE_INFO	0x00010	16	Unlogged status messages.
INSTALLLOGMODE_FILESINUSE	0x00020	32	Files currently held in use.
INSTALLLOGMODE_RESOLVESOURCE	0x00040	64	Source resolution requests.
INSTALLLOGMODE_OUTOFDISKSPACE	0x00080	128	Disk space messages.
INSTALLLOGMODE_ACTIONSTART	0x00100	256	Action start messages.
INSTALLLOGMODE_ACTIONDATA	0x00200	512	Action data messages.
INSTALLLOGMODE_PROGRESS	0x00400	1024	Progress messages.
INSTALLLOGMODE_COMMONDATA	0x00800	2048	UI initialization messages.
INSTALLLOGMODE_INITIALIZE	0x01000	4096	UI startup messages sent when a product installation is starting.
INSTALLLOGMODE_TERMINATE	0x02000	8192	UI shutdown messages sent after a product installation has finished.
INSTALLLOGMODE_SHOWDIALOG	0x04000	16384	Messages sent prior to the display of UI dialog.
INSTALLLOGMODE_RMFILESINUSE	0x02000000	33554432	Files currently held in use.
INSTALLLOGMODE_INSTALLSTART	0x04000000	67108864	Installation of product begins. The message contains the product's ProductName and ProductCode.
INSTALLLOGMODE_INSTALLEND	0x08000000	134217728	Installation of product ends. The message contains the product's ProductName, ProductCode, and return value.

Data

This column contains binary information. If the Attribute field is marked with the msidbEmbeddedUI attribute, the information in this field must be a DLL. If the Attribute field is not the msidbEmbeddedUI attribute, the information in this field can be a resource file in any format.

Remarks

To use an embedded user interface, the setup developer must author this functionality into the Windows Installer package. The MsiEmbeddedUI table defines the embedded user interface. The DLL for the embedded UI should export the InitializeEmbeddedUI, EmbeddedUIHandler, and ShutdownEmbeddedUI functions. Packages that do not support an embedded user interface can use the Windows Installer internal user interface.

To run Debugging Tools for Windows on an embedded user interface, use the techniques described in Debugging Custom Actions. Set the value of MsiBreak to MsiEmbeddedUI.

For an example of an embedded custom UI see Using an Embedded UI.
