In hex 10 is equal to sixteen. Now, in binary, since we go by twos 10 equals two. It's the same as saying, "one set of twos and zero ones" because of the value our placeholders represent. In binary, since you only have two digits, every time you count two numbers higher, you have to use a placeholder.
here's example problem from book Forouzan. TCP header ( in hex)=05320017 00000001 000000000 500207FF 00000000. since each hex = 4 bits , we need to first split the above hex as such. 05 32 00 17 00 00 00 01 00 00 00 00 50 02 07 FF 00 00 00 00. source port is 2 bytes take 05 32 = 1330. next 2 bytes as destination address 00 17 == 23 (default TCP ...
Ok thank you i'll check and one more doubt..i said previously that i'm converting the parameters to hex so "CHOL" is converted to "43484f4c" and saved in database but can i form it as a packet structure with RS-232 Frame as (1 start bit, 7 data bits, 1 parity bits, and 2 stop bits).
By using base 16, the string is always treated as hex number even when the '0x' prefix is missing. When using MFC, you can use the CString class. It provides the Format() member function similar to sprintf() and the Replace() function to remove the spaces (use Remove(" ", "")).
Solution 2. Quote: want to send serial port with hex code. Probably you mean 'want to send binary data (that is an array of bytes) to the serial port'. Have a look at the documentation: SerialPort.Write Method (System.IO.Ports) | Microsoft Docs [^]. Posted 14-Oct-20 20:47pm. CPallini.
Solution 1. you can use the strtol [^] function. Specify the base as 16 for hex. long myNumber = strtol((LPCSTR)myString, NULL, 16); //We dont care where the end of the string was for this example, so the 2nd param is NULL. //myNumber = 250; I have the value "50B" in mystring. But while converting, my long variable is showing 0x00000050B itself.
The method header is. public static String dec2Hex(int value) Write a test program that prompts the user to enter a decimal number and displays its hex equivalent. ( Decimal to hex ) Write a recursive method that converts a decimal number into a hex number as a string.
Hex 1 = Decimal 1 Hex A = Decimal 10 Hex F = Decimal 15 Hex 10 = Decimal 16 Hex FF = Decimal 255 The prefix "0x" is just to indicate that it's a number in Hex. Instead of initializing a byte like so: byte b = 0x10; you could as well write it like so: byte b = 16;
To use the code you just need to include the "Bin" project in your solution, add it to your references and then you should be able to start using any of the conversions available. For example, to convert from a hexadecimal string to binary string: C#. string hexData = "AABBCCDD01234567"; string binData = Conversion.HexToBin(hexData);
Solution 2. There are no "hex values" in image. Values cannot be decimal or hexadecimal, they are binary. "Decimal" or "hexadecimal" could only be some strings representing numbers, but not numbers themselves. And the image pixels are based on those bits. The particular representation depends on such thing as "pixel format"; there are quite a few.
