    Description

    LoadFromFile can be used to load a BLOB-type parameter from a file named FileName. The BlobType parameter can be used to set the exact data type of the parameter: it must be one of the BLOB data types. This function simply creates a TFileStream instance and passes it to TParam.LoadFromStream.

    Errors

    If the specified FileName is not a valid file, or the file is not readable, an exception will occur.
