In Obj-C I used to convert an unsigned integer n to a hex string with
NSString *st = [NSString stringWithFormat:@"%2X", n];
I tried for a long time to translate this into Swift language, but unsuccessfully.
Can anyone help me?
In C++, I have two arrays:
char widthchar height
My values (hex) are:
width= 01width = 00height = 00 height= A8
The dimensions are 256x168. I am having a hard time combining the two char values into a string, then converting that string into a "combined" integer for later manipulation.
I've attempted the following without success:
string sImageWidth = string() + width + width;string sImageHeight = string() + height + height;
std::stringstream ssImageWidth;ssImageWidth << width << width;std::string sImageWidth = ssImageWidth.str();
What am I doing wrong? Is there another approach? I'm fairly new to C++ and wrapping my head around C++ coming from a C# background. Thanks!
What is the best way to convert a variable length hex string e.g.
"01A1" to a byte array containing that data.
i.e converting this:
std::string = "01A1";
char* hexArray;int hexLength;
so that when I write this to a file and
hexdump -C it I get the binary data containing
I use net-snmp-5.5-1.x86.exe for Win32
I need set IP addreess to hex format, separated by whitespace using NET-SNMP set command. For example, an IP address 192.168.100.100 converted to Hex format is 0xC0A86464
192.168.100.100 > 0xC0A86464
The correctly set value should return the following value when check with snmpget:
xxx-xxx-xxx-MIB::docsDevServerAddress.0 = Hex-STRING: C0 A8 64 64
snmpset -v 1 -c private 192.168.100.5 docsDevServerAddress.0 x 0xC0 A8 64 64
But when I using this format to set HEX address, I always got errors like this:
'A8: Bad object type: 6', or
'00xA8 Bad object type: 0', and so on, depending on representation of hex format I tried.According to NET-SNMP manual, 'x' is octet string in hex bytes, separated by whitespace.
How to set correct string input format for snmpset to set Hex values I need?
My goal is to extract some strings (in this case filnames) with linux hexdump from a binary file. Currently i think about how this could be technical done and see some huge trouble.
The problem i got is, that there is no indication for the beginning of the string inside the file that i would like to parse, what i only have is hex value that indicates the end of the string (
0000000000FFFF01 ). Because of my poor knowledge in dealing with Hex values i hope that someone could give me some ideas or hints how it would be possible to find the specific part with the strings if there is no offset indikator for it.
What i currently think is that there might be some kind of reference to this blocks but i have no idea how i could find that reference. I already tried to search for some hex values.
