Short (ASCII, 7-bit per character) string storage and comparison optimization in C++

由 主宰稳场 提交于 2019-12-24 19:24:29
问题 In my project I'm using huge set of short strings in ASCII 7-bit and have to process (store, compare, search etc) these strings with maximum performance. Basically, I build some Index array of uint64_t type and each element stores 9 characters of a word and use that index as Numeric element for any string comparison operation. Current implementation works fast, but may be it's possible to improve it a bit if you will.. This function converts up to 9 initial characters to uint64_t value - any

Calculate SMS Length/Parts C#

由 时光毁灭记忆、已成空白 提交于 2019-12-23 02:43:26
问题 I have been asked to help a friend in his application which has an indicator/counter that should show the end-user how many characters have been written in the text box and also how many parts in this written text/SMS ?. The easiest part was about getting the current characters count/length by using TextBox1.Text.Length , but the other part which was resposible for getting how many parts in this SMS text depending on both Arabic/Unicode and English/7Bit languages, and each language has a

Send SOAP messages via WCF with MTOM and Content-Transfer-Encoding: 7-bit

由 匆匆过客 提交于 2019-12-12 03:16:53
问题 I am trying to send a SOAP message via WCF to the IRS, and it keeps getting rejected because my MTOM attachment is formatted incorrectly. I've narrowed down the issue to my Content-Transfer-Encoding value. It is set to Binary (shorthand for 8-bit ). The IRS service wants me to use 7-bit , with an 8-bit-encoded attachment (in other words, encode with UTF-8 and then guarantee that I'm not using any non-ASCII characters). I'm already using a custom message encoder in order to gzip my requests

How to divide a decimal MIDI pitch-bend value into 2 separated 7 bit values correctly?

由 夙愿已清 提交于 2019-12-10 16:42:09
问题 I'm trying to make a sort of custom midi player, to do so I'm using an array that already has memorized correctly the midi messages data like this: int array[3000][4]={{time,status,data1,data2},{...},...} when I want my program to send the midi message (so that it can be played) I call this array and do the needed distinctions between noteon/off, pitch-bend and such. The pitch-bend value (ranging from 0 to 16383, but usually is around 8192 which means no pitch shifting) is all memorized in

Encoding an integer in 7-bit format of C# BinaryReader.ReadString

由 廉价感情. 提交于 2019-12-03 07:26:23
问题 C# 's BinaryReader has a function that according to MSDN, reads an integer encoded as "seven bit integer", and then reads a string with the length of this integer. Is there a clear documentation for the seven bit integer format (I have a rough understanding that the MSB or the LSB marks whether there are more bytes to read, and the rest bits are the data, but I'll be glad for something more exact). Even better, is there a C implementation for reading and writing numbers in this format? 回答1:
