The get_Type method retrieves the Type property of the Error object. This method returns a msmErrorType value indicating the type of error represented by this object.

Syntax

C++HRESULT get_Type(
  [out]  msmErrorType *ErrorType
);

Parameters

ErrorType [out]

A pointer to a location in memory that receives the type of error.

msmErrorType	Value	Description
msmErrorLanguageUnsupported	1	A request was made to open a module with a language not supported by the module. No more general language is supported by the module. Adds msmErrorLanguageUnsupported to the Type property and the requested language to the Language Property (Error Object). All Error object properties are empty. The OpenModule function returns ERROR_INSTALL_LANGUAGE_UNSUPPORTED (as HRESULT).
msmErrorLanguageFailed	2	A request was made to open a module with a supported language but the module has an invalid language transform. Adds msmErrorLanguageFailed to the Type property and the applied transform's language to the Language Property of the Error object. This may not be the requested language if a more general language was used. All other properties of the Error object are empty. The OpenModule function returns ERROR_INSTALL_LANGUAGE_UNSUPPORTED (as HRESULT).
msmErrorExclusion	3	The module cannot be merged because it excludes, or is excluded by, another module in the database. Adds msmErrorExclusion to the Type property of the Error object. The ModuleKeys property or DatabaseKeys property contains the primary keys of the excluded module's row in the ModuleExclusion table. If an existing module excludes the module being merged, the excluded module's ModuleSignature information is added to ModuleKeys. If the module being merged excludes an existing module, DatabaseKeys contains the excluded module's ModuleSignature information. All other properties are empty (or -1).
msmErrorTableMerge	4	Merge conflict during merge. The value of the Type property is set to msmErrorTableMerge. The DatabaseTable property and DatabaseKeys property contain the table name and primary keys of the conflicting row in the database. The ModuleTable property and ModuleKeys property contain the table name and primary keys of the conflicting row in the module. The ModuleTable and ModuleKeys entries may be null if the row does not exist in the database. For example, if the conflict is in a generated FeatureComponents table entry. When merging a configurable merge module, configuration may cause these properties to refer to rows that do not exist in the module.
msmErrorResequenceMerge	5	There was a problem resequencing a sequence table to contain the necessary merged actions. The Type property is set to msmErrorResequenceMerge. The DatabaseTable and DatabaseKeys properties contain the sequence table name and primary keys (action name) of the conflicting row. The ModuleTable and ModuleKeys properties contain the sequence table name and primary key (action name) of the conflicting row. When merging a configurable merge module, configuration may cause these properties to refer to rows that do not exist in the module.
msmErrorFileCreate	6	Not used.
msmErrorDirCreate	7	There was a problem creating a directory to extract a file to disk. The Path property contains the directory that could not be created. All other properties are empty or -1.
msmErrorFeatureRequired	8	A feature name is required to complete the merge, but no feature name was provided. The Type property is set to msmErrorFeatureRequired. The DatabaseTable and DatabaseKeys contain the table name and primary keys of the conflicting row. The ModuleTable and ModuleKeys properties contain the table name and primary keys of the row cannot be merged. When merging a configurable merge module, configuration may cause these properties to refer to rows that do not exist in the module. If the failure is in a generated FeatureComponents table, the DatabaseTable and DatabaseKeys properties are empty and the ModuleTable and ModuleKeys properties refer to the row in the Component table causing the failure.
msmErrorBadNullSubstitution	9	Substitution of a Null value into a non-nullable column. This enters msmErrorBadNullSubstitution in the Type property and enters "ModuleSubstitution" and the keys from the ModuleSubstitution table for this row into the ModuleTable property and ModuleKeys property. All other properties of the Error object are set to an empty string or -1. This error causes the immediate failure of the merge and the MergeEx function to return E_FAIL.
msmErrorBadSubstitutionType	10	Substitution of Text Format Type or Integer Format Type into a Binary Type data column. This type of error returns msmErrorBadSubstitutionType in the Type property and enters "ModuleSubstitution" and the keys from the ModuleSubstitution table for this row into the ModuleTable property. All other properties of the Error object are set to an empty string or -1. This error causes the immediate failure of the merge and the MergeEx function to return E_FAIL.
msmErrorMissingConfigItem	11	A row in the ModuleSubstitution table references a configuration item not defined in the ModuleConfiguration table. This type of error returns msmErrorMissingConfigItem in the Type property and enters "ModuleSubstitution" and the keys from the ModuleSubstitution table for this row into the ModuleTable property. All other properties of the Error object are set to an empty string or -1. This error causes the immediate failure of the merge and the MergeEx function to return E_FAIL.
msmErrorBadNullResponse	12	The authoring tool has returned a Null value for an item marked with the msmConfigItemNonNullable attribute. An error of this type returns msmErrorBadNullResponse in the Type property and enters "ModuleSubstitution" and the keys from the ModuleSubstitution table for for the item into the ModuleTable property. All other properties of the Error object are set to an empty string or -1. This error causes the immediate failure of the merge and the MergeEx function to return E_FAIL.
msmErrorDataRequestFailed	13	The authoring tool returned a failure code (not S_OK or S_FALSE) when asked for data. An error of this type will return msmErrorDataRequestFailed in the Type property and enters "ModuleSubstitution" and the keys from the ModuleSubstitution table for the item into the ModuleTable property. All other properties of the Error object are set to an empty string or -1. This error causes the immediate failure of the merge and the MergeEx function to return E_FAIL.
msmErrorPlatformMismatch	14	Indicates that an attempt was made to merge a 64-bit module into a package that was not a 64-bit package. An error of this type returns msmErrorPlatformMismatch in the Type property. All other properties of the error object are set to an empty string or -1. This error causes the immediate failure of the merge and causes the Merge function or MergeEx function to return E_FAIL.
