I have a program reading one file and I want to read multiple files so I wrote a script to read those files and send them to the program (args in main) but some how it is not getting the input. I wanted to know the possible ways that I can send info to args(1).
Instead of piping the files to Java (via |) you should simply invoke your Scala program with the JPG argument appended. (I'm assuming Scala since that's what you have tagged your question with.)
Something like:
scala YourScalaProgram tmp.jpg
assuming that all necessary jars, etc., are on your CLASSPATH.

I have a problem to cd into my usb drive (F:) using PowerShell and I can't use variables becouse I am starting PowerShell with Start-Process. I tried using
cd (Get-Volume -FileSystemLabel NameOfUsb).DriveLetter:
and it almost works but "F" has a space after it and ":" is in new line so it spits out error.
Is there any way to do it? It don't have to be using that method
You really should include the full Start-Process line you are trying to run. However, this should do what you want.
cd "$((Get-Volume -FileSystemLabel NameOfUsb).DriveLetter):\"

I am trying to recover a word document that was using 97-2003 version. I do not remember why I did this, but I saved off the Compound File streams into a folder, and it is definitely something I would like to have back as the original document. Is there any solution for this?
Thanks!
Sure, you should theoretically be able to restore it.
You should be able to create a root compound document using
StgCreateDocfile() // or StgCreateStorageEx()
You will need the IStorage* pointer from this if it succeeds.
If you have a folder in your folder, you are going to have to create sub storages for each folder--and do it recursively. The API is IStorage::CreateStorage() ... look it up.
If you have a file in a folder, then a stream needs to be created in the storage that is equivalent to the folder. To create a stream, use IStorage::CreateStream()...look up arguments.
Looking at your screen shot, it has some streams named something like [1]CompObj or [5]SummaryDocumentInformation. For the [n] part, that is probably the equivalent of _T('\00n') where n is 1 or 5 or whatever--it's probably a control character. I've seen that in compound files. If you want to investigate, create a Word 97-2003 document and save as a .doc file and examine the structure.
So, something like [1]CompObj is really _T("\001CompObj")
The stuff above about [n] in your file names is an educated/experienced guess.

In Windows 7, I need to use Maple to export the Tex code into a text file.
In Command-line Maple, I type latex(LambertW(x), "C:/Users/Bravo/Desktop/out.txt"); to do this, but the result is:
{\rm W} \left(x\right)
That is not right, why does it happen ? Is there any method to solve this problem ?
Yeah, that is a bug in Maple. You can try latex(subs(LambertW=lambertW,erf=Erf,arctanh=Artanh,LambertW(x)));

I have doudt, Is scala interpreter(REPL) compiles the command and run by the JVM like how the scalac compiles a program ?
Simply Does it work like any other normal interpreter ?
The standard Scala interpreter, as experienced in the REPL for example, is a variant of the compiler that takes input, wraps it in an invisible object and compiles it on the fly (like any other regular Scala program), then runs the body of that virtual object.
The Scala Meta project might offer a different approach of a more direct interpretation without going through full-to-byte-code compilation.

I am trying to run this code, but have reached a dead end due to my inexperience.
http://dde.binghamton.edu/download/camera_fingerprint/
The code is trying to call the Cpp fucntion mdwt in MATLAB, and that gives error. I changed the function call in MATLAB to coder.ceval but that gives the error "Too many output arguments." I would be grateful to anyone who would point out what I am doing wrong in implementing this code. Thanks in advance!
These files are source code for mex functions, which can be compiled using the mex command. The compile.m from the zip file contains the necessary commands to compile the mex files.
