• VS 2008 SP1 text editor flickering over remote desktop connection

  - by AltairDusk

  I am connecting from a Windows 7 x64 machine to my dev machine running Windows XP SP3 using the built in remote desktop client. For most apps it works fine with no problems, for Visual Studio whenever I am typing the entire text editor keeps redrawing. I stumbled across this question: http://stackoverflow.com/questions/873849/vs-2008-sp1-over-remote-desktop-constant-repainting and I have tried all of the suggestions in it to no effect, including resetting all VS settings back to default then disabling the suggested settings. Has anyone found a reliable solution to this? I feel like I'm going insane with the screen constantly refreshing when I'm working from home. Some additional information: Remote Desktop is set to run at 1680x1050, 15bit color, Low-speed broadband for the experience setting with all but Visual styles and Persistent bitmap caching unchecked. Visual Studio 2008 Team System is running on the dev machine with Service Pack 1 and Power Commands installed.

• Quicker searching in JScript using the Bash

  - by gentlesea

  I am using the following JScript code to search for a string inside a file: var myFile = aqFile.OpenTextFile(fileToSearchIn, aqFile.faRead, aqFile.ctANSI); while(!myFile.IsEndOfFile()) { s = myFile.ReadLine(); if (aqString.Find(s, searchString) != -1) Log.Checkpoint(searchString + " found.", s); } myFile.Close(); This is rather slow. I was thinking about using bash commands in order to speed up the search in file process: var WshShell = new ActiveXObject("WScript.Shell"); var oExec = WshShell.Exec("C:\\cygwin\\bin\\bash.exe -c 'cat \"" + folderName + "/" + fileName + "\"'"); while (!oExec.StdOut.AtEndOfStream) Log.Checkpoint(oExec.StdOut.ReadLine()); while (!oExec.StdErr.AtEndOfStream) Log.Error(oExec.StdErr.ReadLine()); Since every time bash.exe is started a new window opens the searching is not faster than before. Is there a possibility to have the bash run in the background using another switch?

• using git on android

  - by Dave

  Hi all, I have a desktop application using git for synchronization. I have also an android application which do the same as the desktop, but I don't know how to do the synchronization part on it. I haven't found any implementation of git on android. I found a jgit, but its unwell documented and I was not able to do even a commit with that. I was thinking about remote commands to my git server from my android app, but this is really a tease for me. Could you tell me if any other git implementation which can be used on android exists? If you have any idea how to solve that, please tell me. Thanks for reply, Dave

• Delphi 7: how to execute shell command and check the result?

  - by mawg

  I'm using Delphi 7 and can't predict the target version of Windows. I need to create a database (probably MySql, but might be something else) and define some table structures. I do not need to populate any data. Unfortunately, all of the ADO components seem to expect that a database already exists and they will then allow you to manipulate it. So, since it's only a few simple commands, I thought that I might as well use ShellExectute(). Agree? Disagree? Can anyone give me a sample code which will attempt to run "MySql --version" and let me check the result? After that I should be able to figure it out for myself. Thanks.

• Using Connection Based State with Apache2

  I am writing an HTTPS based application using Apache2 as the web server, and python as the language (not sure which framework or Apache2 mod yet). After clients (which are not web browsers) first establish an HTTPS connection to the server, they are expected to send an authentication message. If authentication is successful, they are able to send more commands, until the connection is closed (HTTP 1.1 will be used, with a long keep alive time). My question is, is it possible to have state associated with the connection? I don't want the client to have to send cookies or session ids -- the HTTPS application should be able to figure out the session based on the connection that each request belongs to...the question is how?

• Native Mouse events with Flash and Selenium

  - by Dan at Demand

  I understand that Selenium does not support Flash, but it is my understanding that I should be able to do some simplistic testing of Flash by using Selenium's built in native mouse support and doing mouse up/down events based on coordinates. Is this correct? I can't seem to get it working. I'm trying to test on this page: http://mandy-mania.blogspot.com/2010/04/sneak-peek-of-final-season-of-lost-dvd.html and all I'm trying to do is click on the flash object so it plays the video. I've tried all sorts of commands, MouseOver, MouseDown, MouseDownAt, MouseUp, MouseUpAt, etc. So, I'm wondering if this just theoretically doesn't work or if I'm just doing something wrong. The xpath I'm using is //object[@id='player'], although I've tried a number of different combinations. And yes, I've also tried just the straight click command. Any suggestions? Thanks!

• How many cron jobs are too many?

  - by guitar-

  I have a couple of cron jobs for basic maintenance which aren't very resource-intensive. I also have custom task scheduling (which is just calling a .php file and passing information via GET, ie: cronjob.php?param1=param ...). These can add up pretty quickly. These just call system commands and run external programs (Nmap is one of them). They usually don't take long either. Anyway, can anyone tell me, roughly what point is too many? I know it's hard to say since it depends on what job is being run and how often, but at what point does the crontab program start "struggling"? Anyone have any idea? Thanks.

• Windows 7 interfering with smart cards

  - by Dennis

  I have an application that uses the PC/SC API to communicate with smart cards. On Windows 7, I get strange results: the data returned from the cards is inconsistent and invalid with certain commands. If I disable the Smart Card Plug and Play service in group policy then everything works fine. Has anyone experienced anything similar? Is there any way to get the smart card plug and play service to play nice? It would be nice to not have to disable it...

• Shell Script Sequencing with Rake

  - by Haseeb Khan

  Hi All, I am working on a rake utility and want to implement something mentioned below: There are some shell commands in a sequence in my Rake file. What I want is that the sequence should wait for the previous command to finish processing before it moves to the next one. sh "git commit -m \"#{args.commit_message}\"" do |ok, res| # Do some processing end sh "git push heroku master" So, in the above example what I want is that sh "git push heroku master" shouldn't be executed until the processing in the sh "git commit -m \"#{args.commit_message}\"" do |ok, res| # Do some processing end is completed. Also another nice to have would be that if I can store the output of the shell command in a Ruby variable so it can be used in further manipulation if required. Looking forward to a reply from the fellow community member shortly. Thanks in advance.

• Using FTP from PHP CURL

  I can't figure out how to use CURL's FTP, specifically, how to issue FTP commands from my PHP code: <?php $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, 'ftp://ftp.microsoft.com/'); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); curl_setopt($ch,CURLOPT_POSTQUOTE,array('CWD bussys/','LIST')); /* ?!! */ echo '<hr><pre>'.htmlspecialchars(curl_exec($ch)).'</pre><hr>'; ?> In my example above I want to get a directory listing of bussys, but instead I get a listing of the main (FTP root) directory.

• Android interacting with HTML5 tutorial?

  - by Adam

  I've been looking at using a WebView to display an HTML5 webpage, where the novel features of the mobile device (GPS, compass, accelerometer, camera, etc) can be fed back into the web page. I was wondering if there were any good tutorials showing these functions interacting with the webview. So far I've found ways for the WebView to send javascript commands to the web page, but those interactions haven't been triggered from outside the web view (such as upon receiving an intent from the GPS or accelerometer). Note: The HTML5 Geolocation API is not what I'm interested in. I'm interested in the web page <- WebView interactions, as noted here: http://android-developers.blogspot.com/2008/09/using-webviews.html

• Best way for programmers to edit XAML

  - by JessicaB

  I was wondering how programmers chose to edit XAML. Most of the programmers I speak to seem to edit the raw XML, but that seems nuts to me since it is such a natural thing for a more visual editor (of course you often have to get down to the raw code ultimately, but isn't there a better way to lay out a grid, or edit a template, or add non c# triggers or manage commands? The one that really set me off was editing a menu -- Visual Studio 1.0 had a better menu editor for C++ than the raw XAML editing experience.) When I edit .aspx files I use a visual editor much of the time, and then for the raw stuff I get into the html code. I am aware of Expression Blend, but that seems far more focused on artistic types and GUI experts rather than programmers. Does anyone have recommendations for a better editor for XAML than VS? Especially so since VS seems to have real nasty problems with XAML editing too, like bugginess and poor performance? Appreciate your helping this XAML newbie.

• Tracking object entries when "playing" a Windows Enhanced Metafile

  - by lzcd

  One of my current projects requires that I work out what colours are being used in an EMF file. I have been able to successfully whip up a file parser in C# that notes all references to colours... but haven't had any luck tracking which objects are in use across the entire file so I can apart colours that are referenced from colours that are used to paint on screen. The older style WMF files are easy as the object library starts at zero and one can simply track each "Create Object" style command... but EMF files are proving to be trickier as there seems to be preexisting entries in the library (if the "Select Object" commands I'm seeing are to be believed). Would anyone be able to either enlighten me on how to track objects in the library correctly with EMF files... or suggest an easier alternative to work out which colours are actually being used in the file (as opposed to just being defined)?

• How to traverse the item in the collection in a List or Observable collection?

  - by Ashish Ashu

  I have a collection that is binded to my Listview. I have provided options to user to "move up" "move down" the selected item in the list view. I have binded the selected item of the listview to my viewmodel, hence I get the item in the collection on which user want to do the operation. I have attached "move up" "move down" commands in my viewmodel. I want what is the best way to move up and down in the collection in the collection which is reflected in the list view. Please suggest.

• Running Sybase ISQL scripts from windows batch file

  - by user1328709

  I have already researched on this site as well as on google extensively for this. I have created a number of batch files that perform certain automated transactions(backups etc) on our production database. i want to further simplify my end of day processes by taking the dumps using a script that accepts input of some parameters. the script is able to login the isql prompt but unable to do the execution of the commands. @ECHO ***Started*** @ECHO Enter MonthDay(MMDD) SET /p md= @ECHO %md% mkdir \\10.20.1.17\arch\212%md%_banking set run=isql -Uuser -SORBITS -Ppass %run% @echo dump database banking to '/media/newArch/212%md%_banking/212%md%EOD_banking.dmp' with compression=5 @echo dump database master to '/media/newArch/212%md%_banking/212%md%EOD_master.dmp' @echo go pause I have been unsuccessful at putting these in a separate script file because the script itself uses a passed parameter. Please give me hints and links to Thanks

• PATH and CLASSPATH in Windows7 7 / Eclipse

  - by Richard Knop

  So I would like to set PATH and CLASSPATH system variables so I can use javac and java commands in the command line. I can just compile and run java programs in eclipse but I would also like to be able to run them through command line. This is where I have Java installed: C:\Program Files (x86)\Java jdk1.6.0_20 jre6 And this is where eclipse stores my Java projects: D:\java-projects HelloWorld bin HelloWorld.class src HelloWorld.java I have set up the PATH and CLASSPATH variables like this: PATH: C:\Program Files (x86)\Java\jdk1.6.0_20\bin CLASSPATH: D:\java-projects But it doesn't work. When I write: java HelloWorld Or: java HelloWorld.class I get error like this: Exception in thread “main” java.lang.NoClassDefFoundError: HelloWorld The error is longer, that's just the first line. How can I fix this? I'm mainly interested to be able to run compiled .class programs from the command line, I can do compiling in the eclipse.

• [C#] Onpaint events (invalidated) changing execution order after a period normal operation (runtime)

  - by Luke Mcneice

  Hi all, I have 3 data graphs that are painted via the their paint events. When I have data that I need to insert into the graph I call the controls invalidate() command. The first control's paint event actually creates a bitmap buffer for the other 2 graphs to avoid repeating a long loop. So the invalidate commands are in a specific order (1,2,3). This works well, however when the graphed data reaches the end of the graph window (PictureBox) where the data would normally start scrolling, the paint events begin firing in the wrong order (2,3,1). has anyone came across this before? why might this be happening?

• Eclipse 3.5 and Ubuntu 9.10, subversion client does not work

  - by Cédric Girard

  Hi, I had installed Eclipse 3.5 Yoxos on my Ubuntu 8.04 for month, and run fine. I had upgraded to 9.10 last week, and the subversion plugin does not work since upgrade. When I try to update or commit, Subversion work for hours without any progress in console or progress bars. I can delete files or add them to SVN, but commands wich involve network just hang. SVN run fine using command line. I have already patched the GDK problem. Since this I can cancel update/commit without crashing Eclipse. Regards Cédric

• bash : recursive listing of all files problem

  - by Michael Mao

  Run a recursive listing of all the files in /var/log and redirect standard output to a file called lsout.txt in your home directory. Complete this question WITHOUT leaving your home directory. An: ls -R /var/log/ /home/bqiu/lsout.txt I reckon the above bash command is not correct. This is what I've got so far: $ ls -1R .: cal.sh cokemachine.sh dir sort test.sh ./dir: afile.txt file subdir ./dir/subdir: $ ls -R | sed s/^.*://g cal.sh cokemachine.sh dir sort test.sh afile.txt file subdir But this still leaves all directory/sub-directory names (dir and subdir), plus a couple of empty newlines How could I get the correct result without using Perl or awk? Preferably using only basic bash commands(this is just because Perl and awk is out of assessment scope)

• How do I get code coverage of Perl cgi script when executed by Selenium?

  - by Kurt W. Leucht

  I'm using Eclipse EPIC IDE to write some Perl cgi scripts which call some Perl modules that I have also written. The EPIC IDE lets me configure a Perl CGI "run configuration" which runs my CGI script. And then I've got Selenium set up and one of my unit test files runs some Selenium commands to run my cgi script through its paces. But the coverage report from Module::Build dispatch 'testcover' doesn't show that any of my module code has been executed. It's been executed by my cgi script, but I guess the CGI script was run manually and was not executed directly by my unit test file, so maybe that's why the coverage isn't being recognized. Is there a way to do this right so I can integrate Selenium and unit test files and code coverage all together somehow?

• Colour output piped to less

  - by mmacaulay

  Operating system: Mac OS 10.6.2 I'd like to be able to see colour output when piping certain commands through less. Two examples: I've got ls aliased to ls --color=auto, so I'd like to be able to see colour when I do this: ls -l | less I've also got the color extension turned on in Mercurial, so I'd like to see colour output from: hg diff | less and hg st | less After some googling, it seems like some versions of less support either -r or -R to make this work, but no dice for me. I can't see anything in the man page that looks like what I need. (-r or -R SEEM to be the right options, but again, they don't seem to work)

• How to give highest priority to events generated from main thread than those generated from secondar

  - by martjno

  I have a c++ application written in wxWidgets, which has a main thread (GUI) and a working thread (calculations). The working thread executes commands requested by the main thread and communicates the result to the main thread posting an event after every step of the processing. The problem is that when the working thread is sending many events consecutively, the gui requests made by the user (i.e. interrupt the processing clicking a button) won't be processed by the event handler until the working thread has finished. This is actually happening on OSX, on Windows it works perfectly. I've tried to wxThread::SetPriority and wxThread::Yield but nothing changes. It is working if I put wxThread::Sleep in the working thread, but this slows down very much the processing.
