CreateTransformSummaryInfo Method

[This is preliminary documentation and subject to change.]

This is the CreateTransformSummaryInfo method of the MsiDatabase object. This method creates and populates the summary information stream of an existing transform file. This method fills in the properties with the base and reference ProductCode and ProductVersion properties.

Syntax

object.CreateTransformSummaryInfo reference, storage, long errorConditions, long validation

Parts

object

Database that includes the changes.

reference

Required database that does not include the changes.

storage

Required MsiDatabase object where the transform is to be stored.

errorConditions

Required error conditions that should be suppressed when the transform is applied. Choose either iteNone — none of the following conditions — or combine one or more of the following:

iteAddExistingRow	Adding a row that already exists.
IteDelNonExistingRow	Deleting a row that doesn't exist.
IteAddExistingTable	Adding a table that already exists.
IteDelNonExistingTable	Deleting a table that doesn't exist.
IteUpdNonExistingRow	Updating a row that doesn't exist

validation

Required when the transform is applied to a database; shows which properties should be validated to verify that this transform can be applied to the database. The properties are all contained in the Summary Information Stream Property Set.

Choose either itvNone — validate no properties — or combine one or more of the following:

itvLanguage	Default language must match base database.
ItvProduct	Product must match base database.
ItvPlatform	Platform must match base database.

To validate product version, first choose one or more of these three flags to indicate how much of the version is to be verified.

itvMajVer	Check major version only.
ItvMinVer	Check major and minor version only.
ItvUpdVer	Check major, minor, and update versions.

Then choose one of the following to indicate the required relationship between the product version of the database the transform is being applied to and that of the base database.

itvLess	Applied db version	< base db version
itvLessOrEqual	Applied db version	<= base db version
itvEqual	Applied db version	= base db version
itvGreaterOrEqual	Applied db version	>= base db version
itvGreater	Applied db version	> base db version
