  • Binary to Ascii and back again

    - by rross
    I'm trying to interface with a hardware device via the serial port. When I use software like Portmon to see the messages they look like this: 42 21 21 21 21 41 45 21 26 21 29 21 26 59 5F 41 30 21 2B 21 27 42 21 21 21 21 41 47 21 27 21 28 21 27 59 5D 41 32 21 2A 21 28 When I run them thru a hex to ascii converter the commands don't make sense. Are these messages in fact something different than hex? My hope was to see the messages the device is passing and emulate them using c#. What can I do to find out exactly what the messages are?

  • Send mail via gmail with PowerShell V2's Send-MailMessage

    - by Scott Weinstein
    I'm trying to figure out how to use PowerShell V2's Send-MailMessage with gmail. Here's what I have so far. $ss = new-object Security.SecureString foreach ($ch in "password".ToCharArray()) { $ss.AppendChar($ch) } $cred = new-object Management.Automation.PSCredential "[email protected]", $ss Send-MailMessage -SmtpServer smtp.gmail.com -UseSsl -Credential $cred -Body... I get the following error Send-MailMessage : The SMTP server requires a secure connection or the client was not authenticated. The server response was: 5.5.1 Authentication Required. Learn more at At foo.ps1:18 char:21 + Send-MailMessage <<<< ` + CategoryInfo : InvalidOperation: (System.Net.Mail.SmtpClient:SmtpClient) [Send-MailMessage], SmtpException + FullyQualifiedErrorId : SmtpException,Microsoft.PowerShell.Commands.SendMailMessage Am I doing something wrong, or is Send-MailMessage not fully baked yet (I'm on CTP 3)? Edit - two additional restrictions I want this to be non-interactive, so get-credential won't work The user account isn't on the gmail domain, but an google apps registered domain

  • Selenium Grid with parallel testing using C#/NUnit

    - by seth
    I've got several unit tests written with NUnit that are calling selenium commands. I've got 2 win2k3 server boxes setup, one is running selenium grid hub along with 2 selenium rc's. The other box is running 5 selenium rc's. All of them are registered with the hub as running Firefox on Windows (to keep it simple). In my unit test setup method I've got it connected to the hub's hostname at port 4444. When running the tests, they only run sequentially (as expected). I've done a lot of reading on NUnit's roadmap and how they are shooting for parallel testing abilities. I've seen lots of pointers to using PNUnit in the meantime. However this seems to completely defeat the purpose of the Selenium Grid. Have any of you successfully implemented parallel testing using C#/NUnit connected to a Selenium Grid setup? If so, please elaborate. I'm at a complete loss at how this will/can work using NUnit as it exists now (I'm using version 2.9.3)

  • Bash alias and bash function with several arguments

    - by sanemat
    I want to use both bash alias and bash function with several arguments. I emulate svn sub commands. $ svngrep -nr 'Foo' . $ svn grep -nr 'Foo' . My expectation is both act as below: grep --exclude='*.svn-*' --exclude='entries' -nr 'Foo' . But actual, only alias ('svngrep') does well, function ('svn grep') causes invalid option error. How to write my .bashrc? #~/.bashrc alias svngrep="grep --exclude='*.svn-*' --exclude='entries'" svn() { if [[ $1 == grep ]] then local remains=$(echo $@ | sed -e 's/grep//') command "$svngrep $remains" else command svn "$@" fi }

  • Syntax error on token "QUOTE", VariableDeclaratorId expected after this token

    - by user356812
    I've posted a bigger chunk of the code below. You can see that initially QUOTE was procedural- coded in place. I'm trying to learn how to use declarative design so I want to do the same thing but by using resources. It seems like I need to access the string.xml thru the @R.id tag and identify QUOTE with that string value. But I don't know enough to negotiate this. Any tips? Thanks! public class circle extends Activity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(new GraphicsView(this)); } static public class GraphicsView extends View { //private static final String QUOTE = "Happy Birthday to David."; private final String QUOTE = getString(R.string.quote); ..... @Override protected void onDraw(Canvas canvas) { // Drawing commands go here canvas.drawPath(circle, cPaint); canvas.drawTextOnPath(QUOTE, circle, 0, 20, tPaint);

  • How to generate .sln/.vcproj using qmake

    - by stas
    Hi! I have main.cpp in c:\test folder and do the following: qmake -project qmake -tp vc test.pro The answer is: WARNING: Unable to generate output for: C:/test//Makefile.Debug [TEMPLATE vcapp] WARNING: Unable to generate output for: C:/test//Makefile.Release [TEMPLATE vcapp] But, I don't need make files. I need .vcproj! Environment: Windows XP Pro SP3, MSVC 7.1 and 8.0. Qt is installed in C:\Qt\2010.02 (LGPL version). Commands are run from Qt Command Prompt. What's wrong with it?

  • Windows RT Powershell (PermissionDenied) on New-Object

    - by bazile
    I am trying to instantiate an object in Powershell for Windows RT, but keep getting the following error. PS > $foo = New-Object System.Security.Cryptography.SHA1Managed New-Object : Cannot create type. Only core types are supported in this language mode. At line:1 char:8 + $foo = New-Object System.Security.Cryptography.SHA1Managed + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + CategoryInfo : PermissionDenied: (:) [New-Object], PSNotSupportedException + FullyQualifiedErrorId : CannotCreateTypeConstrainedLanguage,Microsoft.PowerShell.Commands.NewObjectCommand I just spent the last thirty minutes engaged in some pretty heavy Google-fu and was unable to find anything even close to a similar problem, let alone an answer. My hope is that I just need to configure something; my fear is that Windows RT ships with a crippled version of Powershell. Does anyone know which case it is?

  • Ndk-build: CreateProcess: make (e=87): The parameter is incorrect

    - by user1514958
    I get an error when build static lib with NDK on Windows platform: process_begin: CreateProcess( "PATH"\android-ndk-r8b\toolchains\arm-linux-androideabi-4.6\prebuilt\windows\bin\arm-linux-androideabi-ar.exe, "some other commands" ) failed. make (e=87): The parameter is incorrect. make: *** [obj/local/armeabi-v7a/staticlib.a] Error 87 make: *** Waiting for unfinished jobs.... All source files build successfully, and this error occur when compose object files. I don't get this error when build this project in Ubuntu, it occur only on Windows. I suppose I found the issue: second parameter of CreateProcess Win API function lpCommandLine has max length 32,768 characters. But in my case it is more than 32,768 characters. How I can solve this issue?

  • OpenCV 2.0 C++ API using imshow: returns unhandled exception and "bad-flag"

    - by Konrad
    I'm trying to use the new OpenCV 2.0 API in MS Visual C++ 2008 and wrote this simple program: cv::Mat img1 = cv::imread("image.jpg",1); cv::namedWindow("My Window", CV_WINDOW_AUTOSIZE); cv::imshow("My Window", img1); Visual Studio returnes an unhandled exception and the Console returns: OpenCV Error: bad flag (parameter or structure field) (Unrecognized or unsupported array type) in unknown function, file ..\..\..\..\ocv\opencv\src\cxcore\cxarray.cpp, line 2376 The image is not displayed. Furthermore the window "My Window" has a strange caption: "ÌÌÌÌMy Window", which is not dependent on the name. The "old" C API using commands like cvLoadImage, cvNamedWindow or cvShowImage works without any problem for the same image file. I tried a lot of different stuff without success. I appreciate any help here. Konrad

    - by Themasterhimself
    Im using the following guide for getting started with rails for ubuntu 9.10. http://guides.rails.info/getting_started.html I have installed both ruby and gem. gokul@gokul-laptop:~$ ruby -v ruby 1.8.7 (2009-06-12 patchlevel 174) [i486-linux] gokul@gokul-laptop:~$ gem -v 1.3.6 gokul@gokul-laptop:~$ For rails, gokul@gokul-laptop:~$sudo gem install rails doesnt seem to give any response. so used the synaptic package manager for installing it. And it seems to have installed correctly. gokul@gokul-laptop:~$ rails Usage: /usr/bin/rails /path/to/your/app [options] Options: -r, --ruby=path Path to the Ruby binary of your choice (otherwise scripts use env, dispatchers current path). Default: /usr/bin/ruby1.8 -d, --database=name Preconfigure for selected database (options: mysql/oracle/postgresql/sqlite2/sqlite3/frontbase/ibm_db). Default: sqlite3 -D, --with-dispatchers Add CGI/FastCGI/mod_ruby dispatches code to generated application skeleton Default: false --freeze Freeze Rails in vendor/rails from the gems generating the skeleton Default: false -m, --template=path Use an application template that lives at path (can be a filesystem path or URL).

  • How to install wexpect?

    - by Justine
    Hello, I'm running 32-bit Windows XP and trying to have Matlab communicate with Cgate, a command line program. I'd like to make this happen using wexpect, which is a port of Python's module pexpect to Windows. I'm having trouble installing or importing wexpect though. I've put wexpect in the folder Lib, along with all other modules. I can import those other modules but just not wexpect. Commands I've tried include: import wexpect import wexpect.py python wexpect.py install python wexpect.py install --home=~ wexpect install Does anyone have anymore ideas?

  • Installing PHPUnit via PEAR

    - by Ondrej Slinták
    I have problems installing PHPUnit 3.4.6 via PEAR 1.9.0. After I discover channel pear.phpunit.de and try to use one of following commands: pear install phpunit/PHPUnit pear install --alldeps phpunit/PHPUnit pear install --onlyreqdeps phpunit/PHPUnit it fails, giving me following error: No releases available for package "pear.phpunit.de/PHPUnit" install failed I found several threads from people with the same problem, but upgrading PEAR to the newest version usually worked for them. Also there seems to be close to no tutorials for installing PHPUnit for Windows. EDIT: I've also tried to change prefered_state to beta; didn't help. I've also tried to get list of all available packages: pear remote-list -c phpunit It gives me another error: Cannot download non-http URL "/c/categories.xml"

  • Optimizations employed by ORM's

    - by Kartoch
    I'm teaching JEE, especially JPA, Spring and Spring MVC. As I have not so much experience in large projects, it is difficult to know what to present to students about optimisation of ORM. At the present time, I present some classic optimisation tricks: prepared statements (most of ORM implicitely uses it by default) first and second-level caches "write first, optimize later" it is possible to switch off ORM and send SQL commands directly to the database for very frequent, specialized and costly requests Is there any other point the community see about other way to optimize ORM ? I'm especially interested by DAO patterns...

  • java.lang.UnsupportedClassVersionError: Bad version number in .class file?

    - by grmn.bob
    I am getting this error when I include an opensource library that I had to compile from source. Now, all the suggestions on the web indicate that the code was compiled in one version and executed in another version (new on old). However, I only have one version of JRE on my system. If I run the commands: $ javac -version javac 1.5.0_18 $ java -version java version "1.5.0_18" Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_18-b02) Java HotSpot(TM) Server VM (build 1.5.0_18-b02, mixed mode) and check in Eclipse for the properties of the java library, I get 1.5.0_18 Therefore, I have to conclude something else, internal to a class itself, is throwing the exception?? Is that even possible?

  • Python's Popen cleanup

    - by pythonic metaphor
    I wanted to use a python equivalent to piping some shell commands in perl. Something like the python version of open(PIPE, "command |"). I go to the subprocess module and try this: p = subprocess.Popen("zgrep thingiwant largefile", shell=True, stdout=subprocess.PIPE) This works for reading the output the same way I would in perl, but it doesn't clean itself up. When I exit the interpreter, I get grep: writing output: Broken pipe spewed all over stderr a few million times. I guess I had naively hoped all this would be taken care of for me, but that's not true. Calling terminate or kill on p doesn't seem to help. Look at the process table, I see that this kills the /bin/sh process, but leaves the child gzip in place to complain about the broken pipe. What's the right way to do this?

  • How To AutoScroll a DataGridView during Drag and Drop

    - by Mason
    One of the forms in my C# .NET application has multiple DataGridViews that implement drag and drop to move the rows around. The drag and drop mostly works right, but I've been having a hard time getting the DataGridViews to AutoScroll - when a row is dragged near the top or bottom of the box, to scroll it in that direction. So far, I've tried implementing a version of this solution. I have a ScrollingGridView class inheriting from DataGridView that implements the described timer, and according to the debugger, the timer is firing appropriately, but the timer code: SendMessage(Handle, WM_VSCROLL, (IntPtr)scrollDirectionInt, IntPtr.Zero); doesn't do anything as far as I can tell, possibly because I have multiple DataGridViews in the form. I also tried modifying the AutoScrollOffset property, but that didn't do anything either. Investigation of the DataGridView and ScrollBar classes doesn't seem to suggest any other commands or functions that will actually make the DataGridView scroll. Can anyone help me with a function that will actually scroll the DataGridView, or some other way to solve the problem?

  • Debugging with Visual Studio 2010 and VB.NET: Immediate fails due to proection level

    - by marco.ragogna
    It happens quite frequently, more times per day, that with Visual Studio 2010, during the debugging, when I used Immediate commands like: ? NamedVariable I receive the following error: 'NamedVariable' is not declared. It may be inaccessible due to its protection level. In this case also other debug features seems gone, but I can set breakpoints, step into, step over, etc. The solution is stop debugging, clean and rebuild the project, and retry. I am developing a VB.NET Windows Forms application, but it happened with VB.NET WPF projects too. I never had this behavior with VS 2008. Is this a known bug or could it be a problem of my environment/installation? Do you have any idea how to solve this little, but annoying issue?

  • Howto bind a RoutedCommand in a child?

    - by Wouter
    I am having trouble binding a Command that is generated up the UI tree to a control. The following example illustrates my point, the CommandBinding in Grid does not act on the InputBindings in Window. Maybe I do not understand the point of commands, but I would like to have a nice solution for child controls to act on user input on the Window (any control on the Window). <Window x:Class="SilverFit.Menu.Wpf.WpfWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"> <Window.InputBindings> <KeyBinding Command="Close" Key="Escape"/> <MouseBinding Command="Close" MouseAction="RightClick" /> </Window.InputBindings> <Grid Name="grid"> <Grid.CommandBindings> <CommandBinding Command="Close" Executed="Close"/> </Grid.CommandBindings> </Grid> </Window>

  • DLL Config in Mono

    - by nubela
    Hi, I'm trying to pick up Svn.NET (http://www.pumacode.org/projects/svndotnet/) library for use in my Mono project. I tried compiling its mockapp - svnmockapp project (http://www.pumacode.org/projects/svndotnet/browser/trunk/SvnMockApp) , I am able to get the references right and get it compiled right. I understand that it references 2 other modules libapr (libapr-1.so.0) and svn_client (libsvn_client-1.so.0) , by which I've created PumaCode.SvnDotNet.dll.config in /bin/Debug . That is all I've done to tried to try to get the mockapp at least outputting something to show that it is indeed interfacing SVN. Nevertheless, it is not working. Commands that are entered that doesn't interface SVN works fine: $ mono SvnTest.exe -usage Usage: SvnTest <subcommand> [options] Short Options: ~?.V Subcommands: add, checkout[co], status[st], update[up] For help on subcommands, use the -?/--help subcommand option. Commands that tries to access SVN throws an exception: $ mono SvnTest.exe st An exception was thrown by the type initializer for PumaCode.SvnDotNet.AprSharp.Apr Unhandled Exception: System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.NullReferenceException: Object reference not set to an instance of an object at PumaCode.SvnDotNet.SubversionSharp.SvnMockApp.CmdBase.Run (PumaCode.SvnDotNet.SubversionSharp.SvnMockApp.SubCommand sc, System.String[] args) [0x00000] at (wrapper managed-to-native) System.Reflection.MonoMethod:InternalInvoke (object,object[],System.Exception&) at System.Reflection.MonoMethod.Invoke (System.Object obj, BindingFlags invokeAttr, System.Reflection.Binder binder, System.Object[] parameters, System.Globalization.CultureInfo culture) [0x00000] --- End of inner exception stack trace --- at System.Reflection.MonoMethod.Invoke (System.Object obj, BindingFlags invokeAttr, System.Reflection.Binder binder, System.Object[] parameters, System.Globalization.CultureInfo culture) [0x00000] at System.Reflection.MethodBase.Invoke (System.Object obj, System.Object[] parameters) [0x00000] at PumaCode.SvnDotNet.SubversionSharp.SvnMockApp.Application.Run (System.String[] args) [0x00000] at PumaCode.SvnDotNet.SubversionSharp.SvnMockApp.Application.Main (System.String[] args) [0x00000] Using MONO_DEBUG_LEVEL="debug", we get the following log pasted here.

Much appreciated!

  • manipulate objects outside svg with javascript-function inside the svg

    - by Christian Benke
    Hello! I'm embedding a svg-graphic on my website and i'd like to manipulate the rest of the website with javascript-commands which are in the svg - though i'm not sure if this is possible. Let me elaborate: I've got a worldmap in svg, i want to click on a country and this click should run an ajax-call and load relevant information of this country into a div in the html site where the svg is embedded. "onclick="location.href='xxx'"" redirects to the respective site which is fine, but i'd prefer to run a js-function that fetches the site with ajax - but running a javascript-function in the svg only seems to work for functions and elements defined in the svg, not outside of it. Is it basically possible to manipulate anything outside the svg through a js-function in the svg? How? Regards Christian

  • How to check for changes on remote (origin) git repository?

    - by Lernkurve
    Question What are the Git commands to do the following workflow? Scenario: I cloned from a repository and did some commits of my own to my local repository. In the meantime, my colleagues did commits to the remote repository. Now, I want to: Check whether there are any new commits from other people on the remote repository, i.e. "origin"? Say there were 3 new commits on the remote repository since mine last pull, I would like to diff the remote repository's commits, i.e. HEAD~3 with HEAD~2, HEAD~2 with HEAD~1 and HEAD~1 with HEAD. After knowing what changed remotely, I want to get the latest commits from the others. My findings so far For step 2: I know the caret notation HEAD^, HEAD^^ etc. and the tilde notation HEAD ~2, HEAD~3 etc. For step 3: That is, I guess, just a git pull.

  • Importing Thawte trial certificates into a Java keystore

    - by lindelof
    Hello, I'm trying to configure a Tomcat server with SSL. I've generated a keypair thus: $ keytool -genkeypair -alias tomcat -keyalg RSA -keystore keys Next I generate a certificate signing request: $ keytool -certreq -keyalg RSA -alias tomcat -keystore keys -file tomcat.csr Then I copy-paste the contents of tomcat.csr into a form on Thawte's website, asking for a trial SSL certificate. In return I get two certificates delimited with -----BEGIN ... -----END, that I save under tomcat.crt and thawte.crt. (Thawte calls the second certificate a 'Thawte Test CA Root' certificate). When I try to import either of them it fails: $ keytool -importcert -alias tomcat -file tomcat.crt -keystore keys Enter keystore password: keytool error: java.lang.Exception: Failed to establish chain from reply $ keytool -importcert -alias thawte -file thawtetest.crt -keystore keys Enter keystore password: keytool error: java.lang.Exception: Input not an X.509 certificate Adding the -trustcacerts option to either of these commands doesn't change anything either. Any idea what I am doing wrong here?

  • Using Raw SQL with Doctrine

    - by Levi Hackwith
    I have some extremely complex queries that I need to use to generate a report in my application. I'm using symfony as my framework and doctrine as my ORM. My question is this: What is the best way to pass in highly-complex sql queries directly to Doctrine without converting them to the Doctrine Query Language? I've been reading about the Raw_SQL extension but it appears that you still need to pass the query in sections (like from()). Is there anything for just dumping in a bunch of raw sql commands?
