• JDK 7u25: Solutions to Issues caused by changes to Runtime.exec

  - by Devika Gollapudi

  The following examples were prepared by Java engineering for the benefit of Java developers who may have faced issues with Runtime.exec on the Windows platform. Background In JDK 7u21, the decoding of command strings specified to Runtime.exec(String), Runtime.exec(String,String[]) and Runtime.exec(String,String[],File) methods, has been made more strict. See JDK 7u21 Release Notes for more information. This caused several issues for applications. The following section describes some of the problems faced by developers and their solutions. Note: In JDK 7u25, the system property jdk.lang.Process.allowAmbigousCommands can be used to relax the checking process and helps as a workaround for some applications that cannot be changed. The workaround is only effective for applications that are run without a SecurityManager. See JDK 7u25 Release Notes for more information. Note: To understand the details of the Windows API CreateProcess call, see: http://msdn.microsoft.com/en-us/library/windows/desktop/ms682425%28v=vs.85%29.aspx There are two forms of Runtime.exec calls: with the command as string: "Runtime.exec(String command[, ...])" with the command as string array: "Runtime.exec(String[] cmdarray [, ...] )" The issues described in this section relate to the first form of call. With the first call form, developers expect the command to be passed "as is" to Windows where the command needs be split into its executable name and arguments parts first. But, in accordance with Java API, the command argument is split into executable name and arguments by spaces. Problem 1: "The file path for the command includes spaces" In the call: Runtime.getRuntime().exec("c:\\Program Files\\do.exe") the argument is split by spaces to an array of strings as: c:\\Program, Files\\do.exe The first element of parsed array is interpreted as the executable name, verified by SecurityManager (if present) and surrounded by quotations to avoid ambiguity in executable path. This results in the wrong command: "c:\\Program" "Files\\do.exe" which will fail. Solution: Use the ProcessBuilder class, or the Runtime.exec(String[] cmdarray [, ...] ) call, or quote the executable path. Where it is not possible to change the application code and where a SecurityManager is not used, the Java property jdk.lang.Process.allowAmbigousCommands could be used by setting its value to "true" from the command line: -Djdk.lang.Process.allowAmbigousCommands=true This will relax the checking process to allow ambiguous input. Examples: new ProcessBuilder("c:\\Program Files\\do.exe").start() Runtime.getRuntime().exec(new String[]{"c:\\Program Files\\do.exe"}) Runtime.getRuntime().exec("\"c:\\Program Files\\do.exe\"") Problem 2: "Shell command/.bat/.cmd IO redirection" The following implicit cmd.exe calls: Runtime.getRuntime().exec("dir temp.txt") new ProcessBuilder("foo.bat", "", "temp.txt").start() Runtime.getRuntime().exec(new String[]{"foo.cmd", "", "temp.txt"}) lead to the wrong command: "XXXX" "" temp.txt Solution: To specify the command correctly, use the following options: Runtime.getRuntime().exec("cmd /C \"dir temp.txt\"") new ProcessBuilder("cmd", "/C", "foo.bat temp.txt").start() Runtime.getRuntime().exec(new String[]{"cmd", "/C", "foo.cmd temp.txt"}) or Process p = new ProcessBuilder("cmd", "/C" "XXX").redirectOutput(new File("temp.txt")).start(); Problem 3: "Group execution of shell command and/or .bat/.cmd files" Due to enforced verification procedure, arguments in the following calls create the wrong commands.: Runtime.getRuntime().exec("first.bat && second.bat") new ProcessBuilder("dir", "&&", "second.bat").start() Runtime.getRuntime().exec(new String[]{"dir", "|", "more"}) Solution: To specify the command correctly, use the following options: Runtime.exec("cmd /C \"first.bat && second.bat\"") new ProcessBuilder("cmd", "/C", "dir && second.bat").start() Runtime.exec(new String[]{"cmd", "/C", "dir | more"}) The same scenario also works for the "&", "||", "^" operators of the cmd.exe shell. Problem 4: ".bat/.cmd with special DOS chars in quoted params” Due to enforced verification, arguments in the following calls will cause exceptions to be thrown.: Runtime.getRuntime().exec("log.bat \"error new ProcessBuilder("log.bat", "error Runtime.getRuntime().exec(new String[]{"log.bat", "error Solution: To specify the command correctly, use the following options: Runtime.getRuntime().exec("cmd /C log.bat \"error new ProcessBuilder("cmd", "/C", "log.bat", "error Runtime.getRuntime().exec(new String[]{"cmd", "/C", "log.bat", "error Examples: Complicated redirection for shell construction: cmd /c dir /b C:\ "my lovely spaces.txt" becomes Runtime.getRuntime().exec(new String[]{"cmd", "/C", "dir \b \"my lovely spaces.txt\"" }); The Golden Rule: In most cases, cmd.exe has two arguments: "/C" and the command for interpretation.

• With a little effort you can &ldquo;SEMI&rdquo;-protect your C# assemblies with obfuscation.

  - by mbcrump

  This method will not protect your assemblies from a experienced hacker. Everyday we see new keygens, cracks, serials being released that contain ways around copy protection from small companies. This is a simple process that will make a lot of hackers quit because so many others use nothing. If you were a thief would you pick the house that has security signs and an alarm or one that has nothing? To so begin: Obfuscation is the concealment of meaning in communication, making it confusing and harder to interpret. Lets begin by looking at the cartoon below:     You are probably familiar with the term and probably ignored this like most programmers ignore user security. Today, I’m going to show you reflection and a way to obfuscate it. Please understand that I am aware of ways around this, but I believe some security is better than no security.  In this sample program below, the code appears exactly as it does in Visual Studio. When the program runs, you get either a true or false in a console window. Sample Program. using System; using System.Diagnostics; using System.Linq;   namespace ObfuscateMe {     class Program     {                static void Main(string[] args)         {               Console.WriteLine(IsProcessOpen("notepad")); //Returns a True or False depending if you have notepad running.             Console.ReadLine();         }             public static bool IsProcessOpen(string name)         {             return Process.GetProcesses().Any(clsProcess => clsProcess.ProcessName.Contains(name));         }     } }   Pretend, that this is a commercial application. The hacker will only have the executable and maybe a few config files, etc. After reviewing the executable, he can determine if it was produced in .NET by examing the file in ILDASM or Redgate’s Reflector. We are going to examine the file using RedGate’s Reflector. Upon launch, we simply drag/drop the exe over to the application. We have the following for the Main method:   and for the IsProcessOpen method:     Without any other knowledge as to how this works, the hacker could export the exe and get vs project build or copy this code in and our application would run. Using Reflector output. using System; using System.Diagnostics; using System.Linq;   namespace ObfuscateMe {     class Program     {                static void Main(string[] args)         {               Console.WriteLine(IsProcessOpen("notepad"));             Console.ReadLine();         }             public static bool IsProcessOpen(string name)         {             return Process.GetProcesses().Any<Process>(delegate(Process clsProcess)             {                 return clsProcess.ProcessName.Contains(name);             });         }       } } The code is not identical, but returns the same value. At this point, with a little bit of effort you could prevent the hacker from reverse engineering your code so quickly by using Eazfuscator.NET. Eazfuscator.NET is just one of many programs built for this. Visual Studio ships with a community version of Dotfoscutor. So download and load Eazfuscator.NET and drag/drop your exectuable/project into the window. It will work for a few minutes depending if you have a quad-core or not. After it finishes, open the executable in RedGate Reflector and you will get the following: Main After Obfuscation IsProcessOpen Method after obfuscation: As you can see with the jumbled characters, it is not as easy as the first example. I am aware of methods around this, but it takes more effort and unless the hacker is up for the challenge, they will just pick another program. This is also helpful if you are a consultant and make clients pay a yearly license fee. This would prevent the average software developer from jumping into your security routine after you have left. I hope this article helped someone. If you have any feedback, please leave it in the comments below.

• Need advice about pointers and time elapsed program. How to fix invalid operands and cannot convert errors?

  - by user1781382

  I am trying to write a program that tells the difference between the two times the user inputs. I am not sure how to go about this. I get the errors : Line 27|error: invalid operands of types 'int' and 'const MyTime*' to binary 'operator-'| Line |39|error: cannot convert 'MyTime' to 'const MyTime*' for argument '1' to 'int DetermineElapsedTime(const MyTime*, const MyTime*)'| I also need a lot of help in this problem. I don't have a good curriculum, and my class textbook is like cliffnotes for programming. This will be my last class at this university. The C++ teztbook I use(my own not for class) is Sam's C++ One hour a day. #include <iostream> #include<cstdlib> #include<cstring> using namespace std; struct MyTime { int hours, minutes, seconds; }; int DetermineElapsedTime(const MyTime *t1, const MyTime *t2); long t1, t2; int DetermineElapsedTime(const MyTime *t1, const MyTime *t2) { return((int)t2-t1); } int main(void) { char delim1, delim2; MyTime tm, tm2; cout << "Input two formats for the time. Separate each with a space. Ex: hr:min:sec\n"; cin >> tm.hours >> delim1 >> tm.minutes >> delim2 >> tm.seconds; cin >> tm2.hours >> delim1 >> tm2.minutes >> delim2 >> tm2.seconds; DetermineElapsedTime(tm, tm2); return 0; } I have to fix the errors first. Anyone have any ideas??

• I have made an installer for MyProgram but the uninstall shortcut that it creates leaves behind empt

  - by Coder7862396

  I have created an installer for MyProgram using the Visual Studio Installer (Visual Studio Setup Project). It is called "MyProgram Setup.msi". It installs the program fine and if it is uninstalled using the Add/Remove Programs control panel then everything gets removed as it should. The problem is that I want to add a shortcut to the "User's Programs Menu" under the program shortcut called "Uninstall MyProgram". I have tried doing this in 3 different ways and in all 3 ways if MyProgram is uninstalled using that shortcut, the uninstall will leave behind 2 empty folders ("...Program Files\MyCompany\" and "...Program Files\MyCompany\MyProgram\"). Here are the 3 ways that I have tried to make an uninstaller shortcut: 1) A shortcut to a batch or script file Uninstall MyProgram.bat: @ECHO OFF msiexec /uninstall {MyGUID} Uninstall MyProgram.vbs: Dim objShell Set objShell = WScript.CreateObject("WScript.Shell") objShell.Run("START /B msiexec /uninstall {MyGUID}") Set objShell = Nothing 2) Editing the MSI file using Orca.exe I found out how to do this using this guide: http://www.codeproject.com/KB/install/MSIShortcuts.aspx I added the Shortcut Entry to the Shortcut table. Uninstalling worked but it still left behind the 2 empty folders when using this shortcut. 3) From code within MyProgram.exe I modified MyProgram.exe to take a "/uninstall" command line parameter to run "msiexec.exe /uninstall {MyGUID}" and exit itself. Similar to this solution: http://www.codeproject.com/KB/install/DeployUninstall.aspx None of these attempts created a shortcut which can uninstall the program as well as the program's base folders. I don't want to switch to some other installer product such as Inno Setup, NSIS, or WiX.

• How do I connect to SDF on a Mobile device from desktop application?

  - by pitprog

  C# WinForms .Net 3.5 to SQL CE 3.5 on Mobile 6.1 Device I'd like to make a connection from a desktop application to a SDF database on my Windows Mobile device while it's connected via ActiveSync. Visual Studio lets me create a Data Connection to my device. The connections tests OK and I can view the data in the database using Visual Studio. I then create a form and try to fill a DataGridView. When I run the program I get an error that the path to the data base is not valid. How am I supposed to specify the Mobile device path in the connection string? In my App.Config, I've tried variations on the path, but none of them work: connectionString="Data Source=Mobile Device\Program Files\SqlCeViaActiveSync\Orders.sdf" connectionString="Data Source=\Mobile Device\Program Files\SqlCeViaActiveSync\Orders.sdf" connectionString="Data Source=Program Files\SqlCeViaActiveSync\Orders.sdf" connectionString="Data Source=\Program Files\SqlCeViaActiveSync\Orders.sdf" The full connection string section looks like this: <connectionStrings> <add name="SqlCeViaActiveSync.Properties.Settings.OrdersConnectionString" connectionString="Data Source=Mobile Device\Program Files\SqlCeViaActiveSync\Orders.sdf" providerName="Microsoft.SqlServerCe.Client.3.5" /> </connectionStrings> Also, I did make a reference to Microsoft.SqlServerCe.Client, as I found a few articles that mentioned it was necessary. Can anyone point me to some recent articles/samples or let me know what I'm doing wrong? Thanks!

• How do I create a named temporary file on windows in Python?

  - by Chris B.

  I've got a Python program that needs to create a named temporary file which will be opened and closed a couple times over the course of the program, and should be deleted when the program exits. Unfortunately, none of the options in tempfile seem to work: TemporaryFile doesn't have a visible name NamedTemporaryFile creates a file-like object. I just need a filename. I've tried closing the object it returns (after setting delete = False) but I get stream errors when I try to open the file later. SpooledTemporaryFile doesn't have a visible name mkstemp returns both the open file object and the name; it doesn't guarantee the file is deleted when the program exits mktemp returns the filename, but doesn't guarantee the file is deleted when the program exits I've tried using mktemp1 within a context manager, like so: def get_temp_file(suffix): class TempFile(object): def __init__(self): self.name = tempfile.mktemp(suffix = '.test') def __enter__(self): return self def __exit__(self, ex_type, ex_value, ex_tb): if os.path.exists(self.name): try: os.remove(self.name) except: print sys.exc_info() return TempFile() ... but that gives me a WindowsError(32, 'The process cannot access the file because it is being used by another process'). The filename is used by a process my program spawns, and even though I ensure that process finishes before I exit, it seems to have a race condition out of my control. What's the best way of dealing with this? 1 I don't need to worry about security here; this is part of a testing module, so the most someone nefarious could do is cause our unit tests to spuriously fail. The horror!

• function's return address is different from its supposed value, buffer overflow,

  - by ultrajohn

  Good day everyone! I’m trying to understand how buffer overflow works. I’m doing this for my project in a computer security course I’m taking. Right now, I’m in the process of determining the address of the function’s return address which I’m supposed to change to perform a buffer overflow attack. I’ve written a simple program based from an example I’ve read in the internet. What this program does is it creates an integer pointer that will be made to point to the address of the function return address in the stack. To do this, (granted I understand how a function/program variables get organized in the stack), I add 8 to the buffer variable’ address and set it as the value of ret. I’m not doing anything here that would change the address contained in the location of func’s return address. here's the program: Output of the program when gets excecuted: As you can see, I’m printing the address of the variables buffer and ret. I’ve added an additional statement printing the value of the ret variable (supposed location of func return address, so this should print the address of the next instruction which will get executed after func returns from execution). Here is the dump which shows the supposed address of the instruction to be executed after func returns. (Underlined in green) As you can see, that value is way different from the value printed contained in the variable ret. My question is, why are they different? (of course in the assumption that what I’ve done are all right). Else, what have I done wrong? Is my understanding of the program’s runtime stack wrong? Please, help me understand this. My project is due nextweek and I’ve barely touched it yet. I’m sorry if I’m being demanding, I badly need your help.

• Problem Linking Boost Filesystem Library in Microsoft Visual C++

  - by Scott

  Hello. I am having trouble getting my project to link to the Boost (version 1.37.0) Filesystem lib file in Microsoft Visual C++ 2008 Express Edition. The Filesystem library is not a header-only library. I have been following the Getting Started on Windows guide posted on the official boost web page. Here are the steps I have taken: I used bjam to build the complete set of lib files using: bjam --build-dir="C:\Program Files\boost\build-boost" --toolset=msvc --build-type=complete I copied the /libs directory (located in C:\Program Files\boost\build-boost\boost\bin.v2) to C:\Program Files\boost\boost_1_37_0\libs. In Visual C++, under Project Properties Additional Library Directories I added these paths: C:\Program Files\boost\boost_1_37_0\libs C:\Program Files\boost\boost_1_37_0\libs\filesystem\build\msvc-9.0express\debug\link-static\threading-multi I added the second one out of desperation. It is the exact directory where libboost_system-vc90-mt-gd-1_37.lib resides. In Configuration Properties C/C++ General Additional Include Directories I added the following path: C:\Program Files\boost\boost_1_37_0 Then, to put the icing on the cake, under Tools Options VC++ Directories Library files, I added the same directories mentioned in step 3. Despite all this, when I build my project I get the following error: fatal error LNK1104: cannot open file 'libboost_system-vc90-mt-gd-1_37.lib' Additionally, here is the code that I am attempting to compile as well as a screen shot of the aformentioned directory where the (assumedly correct) lib file resides: #include "boost/filesystem.hpp" // includes all needed Boost.Filesystem declarations #include <iostream> // for std::cout using boost::filesystem; // for ease of tutorial presentation; // a namespace alias is preferred practice in real code using namespace std; int main() { cout << "Hello, world!" << endl; return 0; } Can anyone help me out? Let me know if you need to know anything else. As always, thanks in advance.

• Generic unit test scheduling

  - by Raphink

  Hello, I'm (re)writing a program that does generic unit test scheduling. The current program is a mono-threaded Perl program, but I'm willing to modularize it and parallelize the tests. I'm also considering rewriting it in Python. Here is what I need to do: I have a list of tests, with the following attributes: uri: a URI to test (could be HTTP/HTTPS/SSH/local) ; depends: an associative array of tests/values that this test depends on ; join: a list of DB joints to be added when selecting items to process in this test ; depends_db: additional conditions to add to the DB request when selecting items to process in this test. The program builds a dependency tree, beginning with the tests that have no dependencies ; for each test: a list of items is selected from the database using the conditions (results of depending tests, joints and depends_db) ; the list of items is sent to the URI (using POST or stdin) ; the result is retrived as a YAML file listing the state and comments for the test for each tested item ; the results are stored in the DB ; the test returns, allowing depending tests to be performed. the program generates reports (CSV, DB, graphviz) of the performed tests. The primary use of this program currently is to test a fleet of machines against services such as backup, DNS, etc. The tests can then be: - backup: hosted on the backup machine(s), called through HTTP, checks if the machines' backup went well ; - DNS: hosted on the local machine, called via stdin, checks if the machines' fqdn have a valid DNS entry. Does such a tool/module already exist? What would be the best implementation to achieve this (using Perl or Python)?

• Problem with fork exec kill when redirecting output in perl

  - by Edu

  I created a script in perl to run programs with a timeout. If the program being executed takes longer then the timeout than the script kills this program and returns the message "TIMEOUT". The script worked quite well until I decided to redirect the output of the executed program. When the stdout and stderr are being redirected, the program executed by the script is not being killed because it has a pid different than the one I got from fork. It seems perl executes a shell that executes my program in the case of redirection. I would like to have the output redirection but still be able to kill the program in the case of a timeout. Any ideas on how I could do that? A simplified code of my script is: #!/usr/bin/perl use strict; use warnings; use POSIX ":sys_wait_h"; my $timeout = 5; my $cmd = "very_long_program 1>&2 > out.txt"; my $pid = fork(); if( $pid == 0 ) { exec($cmd) or print STDERR "Couldn't exec '$cmd': $!"; exit(2); } my $time = 0; my $kid = waitpid($pid, WNOHANG); while ( $kid == 0 ) { sleep(1); $time ++; $kid = waitpid($pid, WNOHANG); print "Waited $time sec, result $kid\n"; if ($timeout > 0 && $time > $timeout) { print "TIMEOUT!\n"; #Kill process kill 9, $pid; exit(3); } } if ( $kid == -1) { print "Process did not exist\n"; exit(4); } print "Process exited with return code $?\n"; exit($?); Thanks for any help.

• Problem Loading multiple textures using multiple shaders with GLSL

  - by paj777

  I am trying to use multiple textures in the same scene but no matter what I try the same texture is loaded for each object. So this what I am doing at the moment, I initialise each shader: rightWall.SendShaders("wall.vert","wall.frag","brick3.bmp", "wallTex", 0); demoFloor.SendShaders("floor.vert","floor.frag","dirt1.bmp", "floorTex", 1); The code in SendShaders is: GLuint vert,frag; glEnable(GL_DEPTH_TEST); glEnable(GL_TEXTURE_2D); char *vs = NULL,*fs = NULL; vert = glCreateShader(GL_VERTEX_SHADER); frag = glCreateShader(GL_FRAGMENT_SHADER); vs = textFileRead(vertFile); fs = textFileRead(fragFile); const char * ff = fs; const char * vv = vs; glShaderSource(vert, 1, &vv, NULL); glShaderSource(frag, 1, &ff, NULL); free(vs); free(fs); glCompileShader(vert); glCompileShader(frag); program = glCreateProgram(); glAttachShader(program, frag); glAttachShader(program, vert); glLinkProgram(program); glUseProgram(program); LoadGLTexture(textureImage, texture); GLint location = glGetUniformLocation(program, textureName); glActiveTexture(GL_TEXTURE0); glBindTexture(GL_TEXTURE_2D, texture); glUniform1i(location, 0); And then in the main loop: rightWall.UseShader(); rightWall.Draw(); demoFloor.UseShader(); demoFloor.Draw(); Which ever shader is initialised last is the texture which is used for both objects. Thank you for your time and I appreciate any comments.

• Getting a handle on GIS math, where do I start?

  - by Joshua

  I am in charge of a program that is used to create a set of nodes and paths for consumption by an autonomous ground vehicle. The program keeps track of the locations of all items in its map by indicating the item's position as being x meters north and y meters east of an origin point of 0,0. In the real world, the vehicle knows the location of the origin's lat and long, as it is determined by a dgps system and is accurate down to a couple centimeters. My program is ignorant of any lat long coordinates. It is one of my goals to modify the program to keep track of lat long coords of items in addition to an origin point and items' x,y position in relation to that origin. At first blush, it seems that I am going to modify the program to allow the lat long coords of the origin to be passed in, and after that I desire that the program will automatically calculate the lat long of every item currently in a map. From what I've researched so far, I believe that I will need to figure out the math behind converting to lat long coords from a UTM like projection where I specify the origin points and meridians etc as opposed to whatever is defined already for UTM. I've come to ask of you GIS programmers, am I on the right track? It seems to me like there is so much to wrap ones head around, and I'm not sure if the answer isn't something as simple as, "oh yea theres a conversion from meters to lat long, here" Currently, due to the nature of DGPS, the system really doesn't need to care about locations more than oh, what... 40 km? radius away from the origin. Given this, and the fact that I need to make sure that the error on my coordinates is not greater than .5 meters, do I need anything more complex than a simple lat/long to meters conversion constant? I'm knee deep in materials here. I could use some pointers about what concepts to research. Thanks much!

• capturing CMD batch file parameter list; write to file for later processing

  - by BobB

  I have written a batch file that is launched as a post processing utility by a program. The batch file reads ~24 parameters supplied by the calling program, stores them into variables, and then writes them to various text files. Since the max input variable in CMD is %9, it's necessary to use the 'shift' command to repeatedly read and store these individually to named variables. Because the program outputs several similar batch files, the result is opening several CMD windows sequentially, assigning variables and writing data files. This ties up the calling program for too long. It occurs to me that I could free up the calling program much faster if maybe there's a way to write a very simple batch file that can write all the command parameters to a text file, where I can process them later. Basically, just grab the parameter list, write it and done. Q: Is there some way to treat an entire series of parameter data as one big text string and write it to one big variable... and then echo the whole big thing to one text file? Then later read the string into %n variables when there's no program waiting to resume? Parameter list is something like 25 - 30 words, less than 200 characters. Sample parameter list: "First Name" "Lastname" "123 Steet Name Way" "Cityname" ST 12345 1004968 06/01/2010 "Firstname+Lastname" 101738 "On Account" 20.67 xy-1z 1 8.95 3.00 1.39 0 0 239 8.95 Items in quotes are processed as string variables. List is space delimited. Any suggestions?

• How can I prevent the "... has stopped working" window on my Server 2008 R2 dev box?

  - by serialhobbyist

  I'm using a Windows Server 2008 x64 R2 machine as a development box. Amongst many other things I've got Visual Studio 2008 SP1 installed on it. When I'm working on a project, I sometimes need to use Debug Start without Debugging (Ctrl + F5). If the program throws an exception, I get a new R2-style window appear. I'm pretty sure I didn't see this on my XP box - this is the first time I've developed directly on a server. Is there any way to avoid this - it's really beginning to bug me? E.g. my current project is accessing a WCF service - I'm using Ctrl+F5 to start a console program client. I run it and get the window. The title is the name of the project I've just started and it contains: [insert-project-name-here] has stopped working Windows can check online for a solution to the problem. --> Check online for a solution and close the program --> Close the program --> Debug the program V View problem details. Clicking on "Close the program" will actually close the window and the exception message appears in the console, which is what I want (but without the extra window-faffing). How can I avoid this annoyance?

• Function behaviour on shell(ksh) script

  - by footy

  Here are 2 different versions of a program: this Program: #!/usr/bin/ksh printmsg() { i=1 print "hello function :)"; } i=0; echo I printed `printmsg`; printmsg echo $i Output: # ksh e I printed hello function :) hello function :) 1 and Program: #!/usr/bin/ksh printmsg() { i=1 print "hello function :)"; } i=0; echo I printed `printmsg`; echo $i Output: # ksh e I printed hello function :) 0 The only difference between the above 2 programs is that printmsg is 2times in the above program while printmsg is called once in the below program. My Doubt arises here: To quote Be warned: Functions act almost just like external scripts... except that by default, all variables are SHARED between the same ksh process! If you change a variable name inside a function.... that variable's value will still be changed after you have left the function!! But we can clearly see in the 2nd program's output that the value of i remains unchanged. But we are sure that the function is called as the print statement gets the the output of the function and prints it. So why is the output different in both?

• LuaEdit can't find module when Lua files all in the same folder

  - by joverboard

  I downloaded LuaEdit to use as an IDE and debug tool however I'm having trouble using it for even the simplest things. I've created a solution with 2 files in it, all of which are stored in the same folder. My files are as follows: --startup.lua require("foo") test("Testing", "testing", "one, two, three") --foo.lua foo = {} print("In foo.lua") function test(a,b,c) print(a,b,c) end This works fine when in my C++ compiler when accessed through some embed code, however when I attempt to use the same code in LuaEdit, it crashes on line 3 require("foo") with an error stating: module 'foo' not found: no field package.preload['foo'] no file 'C:\Program Files (x86)\LuaEdit 2010\lua\foo.lua' no file 'C:\Program Files (x86)\LuaEdit 2010\lua\foo\init.lua' no file 'C:\Program Files (x86)\LuaEdit 2010\foo.lua' no file 'C:\Program Files (x86)\LuaEdit 2010\foo\init.lua' no file '.\foo.lua' no file 'C:\Program Files (x86)\LuaEdit 2010\foo.dll' no file 'C:\Program Files (x86)\LuaEdit 2010\loadall.dll' no file '.\battle.dll' I have also tried creating these files prior to adding them to a solution and still get the same error. Is there some setting I'm missing? It would be great to have an IDE/debugger but it's useless to me if it can't run linked functions.

• VB.Net - Launch app on Windows startup

  - by Queops

  We all now the tricky folders where your application runs when you publish your VB.NET to other people, but I won't give up on the benefits of the system (auto-update, you know). Problem is: Program is supposed to startup, or not, with Windows if the user wishes so. I'm saving program preferences into My.Settings. All fine with that. If you debug it it will save the values between sessions. The problem is after deployment. I installed the program on a testing machine. Application works okay, the settings load, if it's the user launching it by themselfs (using shortcut on desktop for example). Now upon restarting the program does indeed start up as I want it to but the My.Settings don't show up! It's like the config file has been erased. If I close program and re-open by clicking shorcut it loads the settings just fine though. So I wonder what's the problem? This is the code I use to save the registry key: regKey = Registry.CurrentUser.OpenSubKey("SOFTWARE\Microsoft\Windows\CurrentVersion\Run", True) regKey.SetValue("ScapeTracker", Chr(34) & Application.ExecutablePath & Chr(34) & " startup") Does what it's supposed to. The startup parameter is needed so the program knows if it's launched on startup on not (to show up on tray and idle there until user decides to use it). So the problem is that I can't use the settings upon restart of Windows, so I'm assuming the VB.Net applications have some extra parameters when launching? How can I solve this?

• C# 3 dimensional array definition issue

  - by George2

  Hello everyone, My following code has compile error, Error 1 Cannot implicitly convert type 'TestArray1.Foo[,,*]' to 'TestArray1.Foo[][][]' C:\Users\lma\Documents\Visual Studio 2008\Projects\TestArray1\TestArray1\Program.cs 17 30 TestArray1 Does anyone have any ideas? Here is my whole code, I am using VSTS 2008 + Vista 64-bit. namespace TestArray1 { class Foo { } class Program { static void Main(string[] args) { Foo[][][] foos = new Foo[1, 1, 1]; return; } } } EDIT: version 2. I have another version of code, but still has compile error. Any ideas? Error 1 Invalid rank specifier: expected ',' or ']' C:\Users\lma\Documents\Visual Studio 2008\Projects\TestArray1\TestArray1\Program.cs 17 41 TestArray1 Error 2 Invalid rank specifier: expected ',' or ']' C:\Users\lma\Documents\Visual Studio 2008\Projects\TestArray1\TestArray1\Program.cs 17 44 TestArray1 namespace TestArray1 { class Foo { } class Program { static void Main(string[] args) { Foo[][][] foos = new Foo[1][1][1]; return; } } } EDIT: version 3. I think I want to have a jagged array. And after learning from the fellow guys. Here is my code fix, and it compile fine in VSTS 2008. What I want is a jagged array, and currently I need to have only one element. Could anyone review whether my code is correct to implement my goal please? namespace TestArray1 { class Foo { } class Program { static void Main(string[] args) { Foo[][][] foos = new Foo[1][][]; foos[0] = new Foo[1][]; foos[0][0] = new Foo[1]; foos[0][0][0] = new Foo(); return; } } } thanks in advance, George

• Cannot generate/run migrations on rails 2.3.4

  - by Brian Roisentul

  I used to work with rails 2.3.2 before and then I decided to upgrade to version 2.3.4. Today I tried to generate a migration(I could do this fine with version 2.3.2) and I got the following error message: C:/Program Files (x86)/NetBeans 6.8/ruby2/jruby-1.4.0/lib/ruby/gems/1.8/gems/rails-2.3.4/lib/initializer.rb:812:in `const_missing': uninitialized constant ActiveSupport (NameError) from D:/Proyectos/Cursometro/www/config/environment.rb:33 from C:/Program Files (x86)/NetBeans 6.8/ruby2/jruby-1.4.0/lib/ruby/gems/1.8/gems/rails-2.3.4/lib/initializer.rb:111:in `run' from D:/Proyectos/Cursometro/www/config/environment.rb:15 from D:/Proyectos/Cursometro/www/config/environment.rb:31:in `require' from C:/Program Files (x86)/NetBeans 6.8/ruby2/jruby-1.4.0/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in `require' from C:/Program Files (x86)/NetBeans 6.8/ruby2/jruby-1.4.0/lib/ruby/gems/1.8/gems/rails-2.3.4/lib/commands/generate.rb:1 from C:/Program Files (x86)/NetBeans 6.8/ruby2/jruby-1.4.0/lib/ruby/gems/1.8/gems/rails-2.3.4/lib/commands/generate.rb:31:in `require' from C:/Program Files (x86)/NetBeans 6.8/ruby2/jruby-1.4.0/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in `require' from script\generate:3 I don't know why this is happening.
