The MsiRecordSetStream function sets a record stream field from a file. Stream data cannot be inserted into temporary fields.

Syntax

C++UINT MsiRecordSetStream(
  __in  MSIHANDLE hRecord,
  __in  UNIT iField,
  __in  LPCTSTR szFilePath
);

Parameters

hRecord [in]

Handle to the record.

iField [in]

Specifies the field of the record to set.

szFilePath [in]

Specifies the path to the file containing the stream.

Return Value

The MsiRecordSetStream function returns the following values:

ERROR_BAD_PATHNAME

An invalid path was supplied.

ERROR_FUNCTION_FAILED

The function failed.

ERROR_INVALID_HANDLE

An invalid or inactive handle was supplied.

ERROR_INVALID_PARAMETER

An invalid parameter was passed to the function.

ERROR_SUCCESS

The function succeeded.

Remarks

The contents of the file specified in the MsiRecordSetStream function is read into a stream object. The stream persists if the record is inserted into the database and the database is committed.

To reset the stream to its beginning you must pass in a Null pointer for szFilePath. Do not pass a pointer to an empty string, "", to reset the stream.

If the function fails, you can obtain extended error information by using MsiGetLastErrorRecord.
