  • What's the environment variable for the path to the desktop?

    - by Scott Langham
    I'm writing a Windows batch file and want to copy something to the desktop. I think I can use this: %UserProfile%\Desktop\ However, I'm thinking, that's probably only going to work on an English OS. Is there a way I can do this in a batch file that will work on any internationalized version? UPDATE I tried the following batch file: REG QUERY "HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders" /v Desktop FOR /F "usebackq tokens=3 skip=4" %%i in (`REG QUERY "HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders" /v Desktop`) DO SET DESKTOPDIR=%%i FOR /F "usebackq delims=" %%i in (`ECHO %DESKTOPDIR%`) DO SET DESKTOPDIR=%%i ECHO %DESKTOPDIR% And got this output: S:\REG QUERY "HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders" /v Desktop HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders Desktop REG_EXPAND_SZ %USERPROFILE%\Desktop S:\FOR /F "usebackq tokens=3 skip=4" %i in (`REG QUERY "HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folder s" /v Desktop`) DO SET DESKTOPDIR=%i S:\FOR /F "usebackq delims=" %i in (`ECHO ECHO is on.`) DO SET DESKTOPDIR=%i S:\SET DESKTOPDIR=ECHO is on. S:\ECHO ECHO is on. ECHO is on.

  • input of while loop to come from output of `command`

    - by Felipe Alvarez
    #I used to have this, but I don't want to write to the disk # pcap="somefile.pcap" tcpdump -n -r $pcap > all.txt while read line; do ARRAY[$c]="$line" c=$((c+1)) done < all.txt The following fails to work. # I would prefer something like... # pcap="somefile.pcap" while read line; do ARRAY[$c]="$line" c=$((c+1)) done < $( tcpdump -n -r "$pcap" ) Too few results on Google (doesn't understand what I want to find :( ). I'd like to keep it Bourne-compatible (/bin/sh), but it doesn't have to be.

  • Instantiating a python class in C#

    - by Jekke
    I've written a class in python that I want to wrap into a .net assembly via IronPython and instantiate in a C# application. I've migrated the class to IronPython, created a library assembly and referenced it. Now, how do I actually get an instance of that class? The class looks (partially) like this: class PokerCard: "A card for playing poker, immutable and unique." def __init__(self, cardName): The test stub I wrote in C# is: using System; namespace pokerapp { class Program { static void Main(string[] args) { var card = new PokerCard(); // I also tried new PokerCard("Ah") Console.WriteLine(card.ToString()); Console.ReadLine(); } } } What do I have to do in order to instantiate this class in C#?

    - by John Isaacks
    I want to learn how to write shell scripts. Particularly I want to write a svn post-commit script to upload files from a test server to a production server. I am sure I will want to write more as I get more into it. I have very little linux/unix knowledge. Can anyone recommend a good book?

  • Checking if a directory contains files

    - by ionn
    How do I check if a directory contains files? Something similar to this: if [ -e /some/dir/* ]; then echo "huzzah"; fi; but which works if the directory contains one or several files (the above one only works with exactly 0 or 1 files).

  • Where can I find a tool to convert a VS solution to a gcc makefile?

    - by Tim
    I know about CMake and bakefile already, but that is not what I am looking for. Is there a tool that will generate a makefile given a VC project? (or at least a first attempt at one) so I don't have to do all the work by hand? Alternatively, is there a tool that makes CMake files? Edit: Following the link below leads me to this: http://www.winehq.org/docs/winemaker That is a great help. I have not tried it yet.

  • Git Status Across Multiple Repositories on a Mac

    - by eapen
    I have been searching for a solution to this for a while and have not found quite what I need. I have several Git Repositories in a folder on my Mac (OSX 10.6) and would like a script or tool that will loop through all the repositories and let me know if any of them needs "commit"-ing. This is my structure Sites   /project1   /project2   /project3 I want the tool to do a "git status" in Sites/project1, Sites/project2, Sites/project3 and let me know if Sites/project2 and Sites/project3 have changes or new files and needs to be Staged/committed The closest script I found that might be hackable is here: http://gist.github.com/371828 but even that script wouldn't run and I get an error: "syntax error near unexpected token `do" which might have been written for *nix.

  • Letter spacing issue with 'overlapping' character

    - by Wesz-T
    I'm having some trouble with a font I found on Google Web Fonts. As you can see in the image posted below, the capital V in 'Versus' overlaps with the 'e' when i'm using Firefox. Though when i'm using Chrome (or IE) it does not overlap and leaves me with an ugly space between the two characters. Is there any way to fix this and make it look like the one in Firefox? Or should I start looking for another font? My HTML: <html> <head> <meta charset="utf-8"> <title>Versus</title> <link rel="stylesheet" type="text/css" href="css/reset.css" /> <link rel="stylesheet" type="text/css" href="css/style.css" /> <link href='http://fonts.googleapis.com/css?family=Marck+Script' rel='stylesheet' type='text/css'> </head> <body> <div> <h1>Versus</h1> </div> </body> My CSS: h1 { font-family: 'Marck Script', cursive; font-size: 100px; color:#444; text-align:center; padding:0 50px; text-shadow: 2px 2px 3px #777; } Thanks in advance!

  • run program multiple times using one line shell command

    - by teehoo
    I have the following gifs on my linux system: $ find . -name *.gif ./gifs/02.gif17.gif ./gifs/fit_logo_en.gif ./gifs/halloween_eyes_63.gif ./gifs/importing-pcs.gif ./gifs/portal.gif ./gifs/Sunflower_as_gif_small.gif ./gifs/weird.gif ./gifs2/00p5dr69.gif ./gifs2/iss013e48788.gif ...and so on What I have written is a program that converts GIF files to BMP with the following interface: ./gif2bmp -i inputfile -o outputfile My question is, is it possible to write a one line command using xargs, awk, find etc. to run my program once for each one of these files? Or do I have to write a shell script with a loop?

  • Compatibility of x-www-browser

    - by rohit.arondekar
    I want to open html files from a shell script. I know that Ubuntu has a command x-www-browser that will open the default browser on the system. I also found via some Googling that the command is part of the debian system. I was wondering if the command is available on non debian based distros. If it isn't is there a standard way of opening an html file in the default browser on a linux OS via command line? Note that I'm using Bash.

  • python script to download xml files on my server

    - by Blankman
    I need a python script that will do the following: connect to a URL, and that URL will return a number like 1200. Use the number, to download xml files named: 1 to x where x is the number from #1. store the files in a particular directory. Sorry I've never written a python script, so if you could guide me along that would be great (maybe with a some comments). I will be running this as a cron job if that matters.

  • How to Send Headers Through PHP Proxy?

    - by blabus
    Okay, so I have an issue with an AJAX request. I currently have this URL: http://www.google.com/images?hl=en&safe=off&gbv=2&tbs=isch%3A1&sa=1&q=cars+imagesize%3A500x500&aq=f&aqi=&aql=&oq=&gs_rfai=&start=0 I then pass it to my proxy script by modifying the string to this: proxy.php?url=http://www.google.com/images?hl=en&safe=off&gbv=2&tbs=isch%3A1&sa=1&q=cars+imagesize%3A500x500&aq=f&aqi=&aql=&oq=&gs_rfai=&start=0 I need to use the PHP proxy script to grab that page's HTML so that I can then parse through it with javascript. However, the problem is that the headers in that URL are also being sent to the proxy script, and as a result, I get a 'malformed or illegal request' error. I'm pretty sure the two different sets of headers are the problem, because if I just replace the original URL string with 'http://wwww.google.com', the proxy returns the HTML of the page correctly. So basically, I don't know how to fix this. I'm a complete PHP noob, and I tried escaping the original URL before I appended it to the 'proxy.php?url=', but that doesn't fix anything. Any ideas? Thanks!

  • why is internet explorer displaying my javascript pagination backwards?

    - by user278457
    Here's a version of the code I'm using, stripped down to just the parts that aren't working. This is all written to generate some basic pagination with jQuery. In Chrome/Safari/Moz, I generate see spans, 1,2,3,4,...,etc When I look in IE7/8, I see etc,...,4,3,2,1 The string seems to be concatenating backwards!! This seems very strange to me, because there's not a whole lot going on in the code here, I can't figure out which bit could be causing problems. Obviously, the 1,2,3,4,...,etc is what I'm aiming for here, so as well as an explanation of why this is an issue, I'd love it if someone could offer a quick fix. myVar = { arr:$.makeArray($('.my_li')) }; var str; str=''; for (s in myVar.arr){ r=parseInt(s,10)+1; str+='<span class="my_class">'+r+'</span>'; } $('#my_other_div').html(str);

  • How to obtain a pointer out of a C++ vtable?

    - by Josh Haberman
    Say you have a C++ class like: class Foo { public: virtual ~Foo() {} virtual DoSomething() = 0; }; The C++ compiler translates a call into a vtable lookup: Foo* foo; // Translated by C++ to: // foo->vtable->DoSomething(foo); foo->DoSomething(); Suppose I was writing a JIT compiler and I wanted to obtain the address of the DoSomething() function for a particular instance of class Foo, so I can generate code that jumps to it directly instead of doing a table lookup and an indirect branch. My questions are: Is there any standard C++ way to do this (I'm almost sure the answer is no, but wanted to ask for the sake of completeness). Is there any remotely compiler-independent way of doing this, like a library someone has implemented that provides an API for accessing a vtable? I'm open to completely hacks, if they will work. For example, if I created my own derived class and could determine the address of its DoSomething method, I could assume that the vtable is the first (hidden) member of Foo and search through its vtable until I find my pointer value. However, I don't know a way of getting this address: if I write &DerivedFoo::DoSomething I get a pointer-to-member, which is something totally different. Maybe I could turn the pointer-to-member into the vtable offset. When I compile the following: class Foo { public: virtual ~Foo() {} virtual void DoSomething() = 0; }; void foo(Foo *f, void (Foo::*member)()) { (f->*member)(); } On GCC/x86-64, I get this assembly output: Disassembly of section .text: 0000000000000000 <_Z3fooP3FooMS_FvvE>: 0: 40 f6 c6 01 test sil,0x1 4: 48 89 74 24 e8 mov QWORD PTR [rsp-0x18],rsi 9: 48 89 54 24 f0 mov QWORD PTR [rsp-0x10],rdx e: 74 10 je 20 <_Z3fooP3FooMS_FvvE+0x20> 10: 48 01 d7 add rdi,rdx 13: 48 8b 07 mov rax,QWORD PTR [rdi] 16: 48 8b 74 30 ff mov rsi,QWORD PTR [rax+rsi*1-0x1] 1b: ff e6 jmp rsi 1d: 0f 1f 00 nop DWORD PTR [rax] 20: 48 01 d7 add rdi,rdx 23: ff e6 jmp rsi I don't fully understand what's going on here, but if I could reverse-engineer this or use an ABI spec I could generate a fragment like the above for each separate platform, as a way of obtaining a pointer out of a vtable.

  • Presentation Issue in an Unordered List

    - by phreeskier
    I'm having an issue with correctly presenting items in an unordered list. The labels are floating left and the related spans that are long in length are wrapping and showing below the label. I need a solution that keeps the related spans in their respective columns. In other words, I don't want long spans to show under the labels. What property can I take advantage of so that I get the desired layout in all of the popular browsers, including IE6? Thanks in advance for the help. My code is as follows: <ul> <li> <label>Name</label> <span><%= Html.Encode(Model.Name) %></span> </li> <li> <label>Entity</label> <span><%= Html.Encode(Model.Entity) %></span> </li> <li> <label>Phone</label> <span><%= Html.Encode(Model.Phone) %></span> </li> </ul> My CSS styling is as follows: ul { display:block; list-style-type:none; margin:0; padding:0; } ul li label { float:left; width:100px; }
