Retrieves the data type of a typed file tag attached to a specific vault item.
int GetFileTagDataType(const QString& qsFileName, const QString& qsTagName);
This method retrieves the data type of a typed file tag, identified by TagName, attached to the vault item (file, directory, or alternate stream) specified by FileName. If there isn't a typed file tag with the specified TagName attached to the specified vault item, this method fails with an error.
The value passed for FileName must be a vault-local absolute path. The value passed for TagName may be up to 4095 characters in length (not including the null terminator).
The value returned by this method will be one of the following (except CBFSSTORAGE_TDT_RAWDATA, which is not applicable):
|CBFSSTORAGE_TDT_RAWDATA||0x0||The tag is untyped and must be addressed by Id.|
|CBFSSTORAGE_TDT_BOOLEAN||0x1||The tag contains Boolean data and must be addressed by name.|
|CBFSSTORAGE_TDT_STRING||0x2||The tag contains String (UTF-16LE) data and must be addressed by name.|
|CBFSSTORAGE_TDT_DATETIME||0x3||The tag contains DateTime data and must be addressed by name.|
|CBFSSTORAGE_TDT_NUMBER||0x4||The tag contains numeric (signed 64-bit) data and must be addressed by name.|
|CBFSSTORAGE_TDT_ANSISTRING||0x5||The tag contains AnsiString (8-bit string) data and must be addressed by name.|
