MsiCreateTransformSummaryInfoW function (msiquery.h)

The MsiCreateTransformSummaryInfo function creates summary information of an existing transform to include validation and error conditions. Execution of this function sets the error record, which is accessible by using MsiGetLastErrorRecord.

Syntax

UINT MsiCreateTransformSummaryInfoW(
  [in] MSIHANDLE hDatabase,
  [in] MSIHANDLE hDatabaseReference,
  [in] LPCWSTR   szTransformFile,
  [in] int       iErrorConditions,
  [in] int       iValidation
);

Parameters

[in] hDatabase

The handle to the database that contains the new database summary information.

[in] hDatabaseReference

The handle to the database that contains the original summary information.

[in] szTransformFile

The name of the transform to which the summary information is added.

[in] iErrorConditions

The error conditions that should be suppressed when the transform is applied. Use one or more of the following values.

Validation flag	Meaning
none 0x00000000	Do not validate properties.
MSITRANSFORM_VALIDATE_LANGUAGE 0x00000001	Default language must match base database.
MSITRANSFORM_VALIDATE_PRODUCT 0x00000002	Product must match base database.

 

Validate product version flags.

Validation flag	Meaning
MSITRANSFORM_VALIDATE_MAJORVERSION 0x00000008	Check major version only.
MSITRANSFORM_VALIDATE_MINORVERSION 0x00000010	Check major and minor versions only.
MSITRANSFORM_VALIDATE_UPDATEVERSION 0x00000020	Check major, minor, and update versions.

 

Product version relationship flags. In the following table the installed version is the version of the package that is being transformed, and the base version is the version of the package that is used to create the transform.

Validation flag	Meaning
MSITRANSFORM_VALIDATE_NEWLESSBASEVERSION 0x00000040	Installed version < base version.
MSITRANSFORM_VALIDATE_NEWLESSEQUALBASEVERSION 0x00000080	Installed version <= base version.
MSITRANSFORM_VALIDATE_NEWEQUALBASEVERSION 0x00000100	Installed version = base version.
MSITRANSFORM_VALIDATE_NEWGREATEREQUALBASEVERSION 0x00000200	Installed version >= base version.
MSITRANSFORM_VALIDATE_NEWGREATERBASEVERSION 0x00000400	Installed version > base version.

 

Upgrade code validation flags.

Validation flag	Meaning
MSITRANSFORM_VALIDATE_UPGRADECODE 0x00000800	UpgradeCode must match base database.

Return value

This function returns UINT.

Remarks

The ProductCode Property and ProductVersion Property must be defined in the Property Table of both the base and reference databases. If MSITRANSFORM_VALIDATE_UPGRADECODE is used, the UpgradeCode Property must also be defined in both databases. If these conditions are not met, MsiCreateTransformSummaryInfo returns ERROR_INSTALL_PACKAGE_INVALID.

• Do not use the semicolon for filenames or paths, because it is used as a list delimiter for transforms, sources, and patches.
• This function cannot be called from custom actions. A call to this function from a custom action causes the function to fail.

Note

The msiquery.h header defines MsiCreateTransformSummaryInfo as an alias which automatically selects the ANSI or Unicode version of this function based on the definition of the UNICODE preprocessor constant. Mixing usage of the encoding-neutral alias with code that not encoding-neutral can lead to mismatches that result in compilation or runtime errors. For more information, see Conventions for Function Prototypes.
