问题 In a query developed with Excel Power Query I would like to replace the table column name with a variable, when I filter rows of a list. Unfortunately, I either get an error message (e.g. Expression Error: Column xx of table was not found) or no row is remaining after filtering even if it should. In the example below the variable #"Filter" (= column name) is set to column "B" and used in the step #"Filter Rows" to filter the rows which contain a '1'. But the result is that no row is shown.

问题 I'm creating a program that reads in input from a midi controller using libusb. How do I properly call libusb_bulk_transfer? Currently I'm receiving the error "LIBUSB_ERROR_NOT_FOUND" every time, and the data that I receive is "P". I've swapped out the function 'libusb_bulk_transfer' with 'libusb_interrupt_transfer' but I still receive the same error: LIBUSB_ERROR_NOT_FOUND Below are the libraries that I currently have included #include <stdlib.h> #include <stdio.h> #include <libusb-1.0

问题 I am trying to understand the difference between raw and managed state. From the docs: Keyed State and Operator State exist in two forms: managed and raw. Managed State is represented in data structures controlled by the Flink runtime, such as internal hash tables, or RocksDB. Examples are “ValueState”, “ListState”, etc. Flink’s runtime encodes the states and writes them into the checkpoints. Raw State is state that operators keep in their own data structures. When checkpointed, they only

问题 I am currently working on transforming my C# AES-GCM cryptography code to PHP. However, after some research, the text encrypted by my PHP system cannot be decrypted by the C# one. I want to know if there is any difference from both codes: C# with BouncyCastle: using Org.BouncyCastle.Crypto; using Org.BouncyCastle.Crypto.Engines; using Org.BouncyCastle.Crypto.Modes; using Org.BouncyCastle.Crypto.Parameters; using Org.BouncyCastle.Security; using System; using System.IO; using System.Text; /
