An ASCII file might be read or interpreted as having NULL-terminated strings, carriage returns & line-feeds, or other control characters, that are intended to be read and acted on. For example, a text reader might look for a line of text, where a line is “however many characters you see before you get to a … Read more
Yes it will; this is true of basically all binaries compiled for 64-bit Linux, not just those written in Go (except for shared libraries, which Go doesn’t rely on) You can set the GOOS and GOARCH environment variables before building: GOOS=windows GOARCH=386 go build (or go install or whatever), etc By default a binary will … Read more
\x indicates hexadecimal notation. See: PHP strings Have a look at an ASCII table to see what 0x00 and 0x04 represent. 0x00 = NULL 0x04 = EOT (End of transmission)
The problem was caused by: Get-Content without -raw splits the file into an array of lines thus destroying the code Text.Encoding interprets the binary code as text thus destroying the code Out-File is for text data, not binary code The correct approach is to use IO.File ReadAllBytes: $base64string = [Convert]::ToBase64String([IO.File]::ReadAllBytes($FileName)) and WriteAllBytes to decode: [IO.File]::WriteAllBytes($FileName, … Read more
Supposing you have mylib.aar in your current directory, try the following: $ unzip myLib.aar -d tempFolder # or other extracting tool # Change whatever you need $ jar cvf myNewLib.aar -C tempFolder/ .
To my knowledge, Java forces you to read a file as bytes rather than being able to block read. If you were serializing Java objects, it’d be a different story. The other examples shown use the DataInputStream class with a File, but you can also use a shortcut: The RandomAccessFile class: RandomAccessFile in = new … Read more
At the bottom level, they are all bits… true. However, some transmission channels have seven bits per byte, and other transmission channels have eight bits per byte. If you transmit ASCII text over a seven-bit channel, then all is fine. Binary data gets mangled. Additionally, different systems use different conventions for line endings: LF and … Read more
There is a more accurate way to check for EOF when working with binary data. It avoids all of the encoding issues that come with the PeekChar approach and does exactly what is needed: to check whether the position of the reader is at the end of the file or not. while (inFile.BaseStream.Position != inFile.BaseStream.Length) … Read more
The problem is the strings in your struct. I found that marshaling types like byte/short/int is not a problem; but when you need to marshal into a complex type such as a string, you need your struct to explicitly mimic an unmanaged type. You can do this with the MarshalAs attrib. For your example, the … Read more
