• Problem with VisualBasic

  - by Michael

  Ok, I am sure this is simple but I am not able to figure it out and people on this site seem to be brains... I will admit this is for homework but it has nothing to do with how to code. Has to do with a silly error that I am unable to resolve. I try to debug and when I debug i get the following error ERROR "Visual Studio cannot start debugging because debut target 'C:\Documents and Settings\user\Desktop\programs6\HuricaneSeasonStatistics\bin\Debug\HuricaneStatistics.exe" is missing. Please build the project and retry, or set the OutputPath and AssemblyName properties appropriate to point a the correct location for the target assembly." I am fairly sure the error is in the OutputPath and or AssemblyName. but I am not sure where to change.

• Is there a recommended command for "hg bisect --command"?

  - by blokeley

  I have an emergent bug that I've got to track down tomorrow. I know a previous hg revision which was good so I'm thinking about using hg bisect. However, I'm on Windows and don't want to get into DOS scripting. Ideally, I'd be able to write a Python unit test and have hg bisect use that. This is my first attempt. bisector.py #!/usr/bin/env python import sys import unittest class TestCase(unittest.TestCase): def test(self): #raise Exception('Exception for testing.') #self.fail("Failure for testing.") pass def main(): suite = unittest.defaultTestLoader.loadTestsFromTestCase(TestCase) result = unittest.TestResult() suite.run(result) if result.errors: # Skip the revision return 125 if result.wasSuccessful(): return 0 else: return 1 if '__main__' == __name__: sys.exit(main()) Perhaps I could then run: hg bisect --reset hg bisect --bad hg bisect --good -r 1 hg bisect --command=bisector.py Is there a better way of doing it? Thanks for any advice.

• what does this code do?

  - by bstullkid

  It looks like this just sends a ping, but whats the point of that when you can just use ping? int main (int argc, char *argv[]) { unsigned int pid = 0; char buffer[2]; char *args[] = { "/bin/ping", "-c", "5", NULL, NULL }; if (argc != 2) return 0; args[3] = strdup(argv[1]); for (;;) { gets(buffer); /* FTW */ if (buffer[0] == 0x6e) break; switch (pid = fork()) { case -1: printf("Error Forking\n"); exit(255); case 0: execvp(args[0], args); exit(1); default: break; } } return 255; }

• Fixing permissions after FTPing ASP.NET code to a Linux system

  - by dnord

  First off, I'm running Mono to run ASP.NET on Linux, but that's not the question. It appears that, every time I clear out my application directory and upload, I have to go back in and fix the permissions. What I'm doing is chmod -R -c 755 /var/www/* ...and there are two questions. What's the deal with having to do this every time I FTP? Feels flaky. Is there a better permissions set than 755? Do I want different permissions for the /bin directory? Or can I fix this all with one fell swoop of chown?

• 'Step Into' is suddenly not working in Visual Studio

  - by Nick LaMarca

  All of a sudden, I have run into an issue where I cannot step into any code through debugging in Visual Studio. The step over works fine, but it refuses to step into (F11) any of my code. This was working before, now all of a sudden it does not. I've tried some things below, but I still had no success: Delete all bin files in every project in my solution, clean solution, re-build solution. Build projects in solution indivdualy Restart machine It an ASP.NET C# application consuming a WCF sevice locally. It is in debug mode. I have a breakpoint set on the page consuming the service. The breakpoint hits, but it will not step into the service code. The ASP.NET site and the service code is all in the same solution. This all of a sudden does not work, it did work before. How can I fix this problem? Adding a breakpoint to the service project I get a warning: Breakpoint will not currently be hit. No symbols have been loaded for this document. I deleted all the bin folders for all the projects and re-built them one by one. They all succeeded, but still I am getting the symbols won't load on any breakpoint I put into any project in the solution other than the ASP.NET project where the breakpoint works. I was able to debug step into all the projects before, this is an all of a sudden thing. Information from the output window..

• Asp.Net C# DllImport problem

  - by user346665

  Hi, I want to import DLL file in my web site project. I have dll file "my.dll" in folder C:\DLLDir and I'm using the code : [DllImport("C:\\DLLDir\\my.dll", EntryPoint = "Out32")] This works ok. But I want to use relative path (web site root path) . I'm trying to put "my.dll" in "bin" or root folder and I'm using the code : [DllImport("my.dll", EntryPoint = "Out32")] but I'm getting the error: Unable to load DLL 'my.dll': The specified module could not be found. (Exception from HRESULT: 0x8007007E) Any ideas?

• What ASP.NET MVC project files should I not add to Subversion

  - by Dan

  this is likely a naive question, but I want to do this right the first time. I have a MVC solution which has the following: Data project - C# Services project - C# MVC Web Project - ASP.NET MVC Test Project Currently, I am using the MVC2 source as a means to debug my own code. I do not plan on checking that in, but I realize once I go back to the MVC2 DLL, my solution will change. I'm pretty sure I just shouldn't check in stuff that changes with each build: the bin folder on the Web project, for example. Is there a list of what not to commit to source control? :)

• Python, how to tell if screen is running.

  - by Joe Spoon

  Hello, I am very new to programming and am trying to run a python code to see if the screen program is running and if it is then to not run the rest of the code. This is what I have and it's not working. !/usr/bin/python import os var1 = os.system ('screen -r /root/screenlog/screen.log') fd = open("/root/screenlog/screen.log") content = fd.readline() while content: if content == "There is no screen to be resumed.": os.system ('/etc/init.d/tunnel.sh') print "The tunnel is now active." else: print "The tunnel is running." fd.close() I know there are probably several things here that don't need to be and quite a few that I'm missing. I will be running this program in cron. Thanks for any help.

• Best practices for using Hg with Grails?

  - by leeand00

  What should I check in/not check in? Since many of the files are sometimes auto-generated I'm not entirely sure how to handle this using version control...does it have something to do with tags? For instance in ANT, I know not to check-in my target/bin directories...but Grails adds another level of confusion to this...since some of code is generated and some of it is not. (It may become clearer as I go...but it seems to be that there needs to be some way of being able to tell what was just generated and what was modified by a developer so that it needs to be placed in version control)

• Custom script in .screenrc

  - by benoror

  Hi. I made a script that spawns a remote shell or runs a local shell whether it's on the current machine or not: #!/bin/bash # By: benoror <[email protected]> # # spawns a remote shell or runs a local shell whether it's on the current machine or not # $1 = hostname if [ "$(hostname)" == "$1" ]; then bash else ssh "$1.local" fi For example, if I'm on server1: ./spawnshell.sh server1 -> runs bash ./spawnshell.sh server2 -> ssh to server2.local I want that script to run automatically in separate tabs in GNU Screen, but I can't make it run, my .screenrc: ... screen -t "@server1" 1 exec /home/benoror/scripts/spawnshell.sh server1 screen -t "@server2" 2 exec /home/benoror/scripts/spawnshell.sh server2 ... But it doesn't works, I've tried without 'exec', with -X option and a lot more. Any ideas ?

• Another question about ASP.NET MVC and a separate project for helper classes

  - by rockinthesixstring

  I know this topic has been discussed to death, but there is one thing that I can't wrap my head around. I'm working on a Web Application using ASP.NET MVC and I come across a scenario where I need a helper class (this usually happens in the early stages of development. So I go ahead and create a helper project in my solution that I use to manage all of my Helper Classes. Now, do I have to build that project and dump the dll in the bin directory every time I make changes to is, or is there a way to have the main web application reference the classes contained within the separate project without the separate build process? I'm just looking for the easiest way to add helper classes without the hastel of building and moving the dll every time I make a change or addition. Also, sorry for the very newbie-esque question here. All of the web apps I've build in the past have all been in the same project (web forms, App_Code, etc).

• Broken if statement

  - by Vladimir Nani

  Maybe I am crazy but how that could be? some == null is always false but debugger goes into if-statement body anyway. Any ideas? I have restarted visual studio I have cleaned every bin/obj folder It is not the case that i don`t understand that WindowsIdentity.GetCurrent() may return null. That was my first idea. var some = new object(); if (some == null) { throw new Exception("hi!"); } else { do(); } My code: private void GetCurrentWindowsIdentity() { var identity = WindowsIdentity.GetCurrent() if (identity == null) { throw new Exception(Errors.IdentityIsNullException); } try { if (CurrentAuthenticationWrapper.AuthenticationType == AuthenticationType.Windows) { CurrentLogin = _identity != null ? _identity.Name : string.Empty; } } catch (Exception ex) { ViewManager.ShowError(ex); } _identity = identity; }

• Publish web application from MSBuild Script using VS2010 targets resets working directory

  - by Raoul

  I am trying to automatically publish and deploy my .Net 4 web application automatically from a build script to be run by our continuous integration server. I am using the new _WPPCopyWebApplication target from VS2010 to perform the publish, however it appears to reset the current working directory of the msbuild project to c:\ this causes my prebuild steps to fail as they have relative paths to some external tools. The task I am running from our master.build file is as follows: <Target Name="PublishWeb"> <MSBuild Projects="$(ProjectPath)" Targets="ResolveReferences;_WPPCopyWebApplication" Properties="WebProjectOutputDir=$(DeployPath);OutDir=$(TempOutputFolder)$(WebOutputFolder)\;OutputPath=$(ProjectPath)\bin\Debug;" /> </Target> This does not happen when using the legacy _CopyWebApplication. Does anyone have any idea how to resolve this problem?

• Python proper use of __str__ and __repr__

  - by Peter

  Hey, My current project requires extensive use of bit fields. I found a simple, functional recipe for bit a field class but it was lacking a few features I needed, so I decided to extend it. I've just got to implementing __str__ and __repr__ and I want to make sure I'm following convention. __str__ is supposed to be informal and concice, so I've made it return the bit field's decimal value (i.e. str(bit field 11) would be "3". __repr__ is supposed to be a official representation of the object, so I've made it return the actual bit string (i.e. repr(bit field 11) would be "11"). In your opinion would this implementation meet the conventions for str and repr? Additionally, I have used the bin() function to get the bit string of the value stored in the class. This isn't compatible with Python < 2.6, is there an alternative method? Cheers, Pete

• Prolog - Finding the current directory, relative directory for 'tell' predicate

  - by Bharat

  I'm having trouble trying to figure out how to get prolog to spit out a text file where I want it to. I'm currently doing a bunch of operations and then using tell('output.txt') to record the output. Now the problem is that when I do this, it creates this file in the SWI \bin\ folder. I was wondering if there's a way to make it create this file in the directory containing the actual .pl file. So even if the file was moved (and it will be), the text file gets created right where the source file is. Long story short, is there a way to get the location of the source file once the source file has been consulted? Many Thanks!

• Why does sh/bash set command line parameter values when trying to set environment variable?

  - by Touko

  A question on basics : While tuning environment variables for a program launched from a script, I ended up with somewhat strange behaviour with sh (which seems to be actually linked to bash) : variable setting seems to mess up with command-line parameters. Could somebody explain why does this happen? A simple script: #! /bin/sh # Messes with $1 ?? set ANT_OPTS=-Xmx512M export ANT_OPTS # Works # export ANT_OPTS=-Xmx512M echo "0 = $0" echo "1 = $1" When I run this with the upper alternative (set + export), the result is as following: $ ./test.sh foo 0 = ./test.sh 1 = ANT_OPTS=-Xmx512M But with lower alternative (export straight), the result is as I supposed: $ ./test.sh foo 0 = ./test.sh 1 = foo There is surely logical explanation, I just haven't figured it out yet. Somebody who does have idea? br, Touko

• Get CruiseControl to talk to github with the correct public key.

  - by Danny Lister

  Hi All, Has anybody installed git and ControlControl and got CruiseControl to pull from GitHub on a window 2003 server. I keep getting public key errors (access denied) - Which is good i suppose as that confirms git is talking to github. However what is not good is that I dont not know where to install the rsa keys so they will be picked up by the running process (git in the context of cc.net). Any help would save me a lot of hair! I have tried installing the keys into; c:\Program Files\Git.ssh Whereby running git bash and cd ~ take me to: c:\Program Files\Git Current error from CC.net is Error Message: ThoughtWorks.CruiseControl.Core.CruiseControlException: Source control operation failed: Permission denied (publickey). fatal: The remote end hung up unexpectedly .

• how sort recursively by maximum fileze and counts files type?

  Hello! I'm beginner in bash programming. I want to display head -n $1 results of sorting files by size in /etc/*.

I compose following code: #!/bash/bin let countF=0; let countD=0; for file in $(du -sk /etc/* |sort +0n | head $1); do if [ -f "file" ] then echo $file; let countF=countF+1; else if [ -d "file" ] then let countD=countD+1; fi done echo $countF echo $countD I have errors at execution. How use find with du, because I must search recursively?

• Sending JSON(jQuery) to PHP and decoding it

  - by dscher

  I can't for the life of me figure out what I'm doing wrong. It seems like it should be simple because I can't find anyone else with this issue but I can't figure out to send basic data via javascript(jQuery) to PHP and decode it. For the sake of simplicity, this is what I have: JAVASCRIPT var json_data = { "name" : "john doe" }; $.ajax({ type: "POST", url: "../bin/process.php", dataType: "json", data: json_data }); and my PHP FILE $arr = json_decode("json_data", true); $fp = fopen('data.txt', "w"); fwrite($fp, $arr['name']); fclose($fp); The file I'm writing ends up with nothing in it. If I do an: fwrite($fp, 'test'); I get a file with the word test in it but no matter what I do I don't get the json data I sent. Can someone please share a thorough example of A to Z. Thanks for any help.

  It takes about minute to achieve 3000 in my comp but I need to know the millionth number in the serie. The definition is recursive so I cannot see any shortcuts except to calculate everything before the millionth number. How can you fast calculate millionth number in the serie? Serie Def n_{i+1} = \floor{ 3/2 * n_{i} } and n_{0}=2. Interestingly, only one site list the serie according to Goolge: this one. Too slow Bash code #!/bin/bash function serie { n=$( echo "3/2*$n" | bc -l | tr '\n' ' ' | sed -e 's@\\@@g' -e 's@ @@g' ); # bc gives \ at very large numbers, sed-tr for it n=$( echo $n/1 | bc ) #DUMMY FLOOR func } n=2 nth=1 while [ true ]; #$nth -lt 500 ]; do serie $n # n gets new value in the function throught global value echo $nth $n nth=$( echo $nth + 1 | bc ) #n++ done

• Couchbase (ex. membase) solution to dump all keys in a bucket

  - by j99

  I was googling around and found various python + tap solutions that should enable me to dump all keys from a bucket but none of them worked for me. I have a bucket at port 11230 and I need to get a dump of all keys in order to fill them into sphinx search engine. If I execute: # python /opt/couchbase/lib/python/tap_example.py 127.0.0.1:11230 I get the following output: info: New bin connection from None error: uncaptured python exception, closing channel <tap.TapConnection connected at 0x7f5d287184d0> (<type 'exceptions.AssertionError'>: [/usr/lib/python2.6/asyncore.py|read|78] [/usr/lib/python2.6/asyncore.py|handle_read_event|428] [/opt/couchbase/lib/python/mc_bin_server.py|handle_read|325]) this error is the same even if I try some other host or port. I also tried many other python scripts that I found on forums and groups but all of them produced the same error. My primary development environment includes PHP & Perl on Debian linux box but I will take any solution that would just dump all the keys into plain text file. Thank you for any help!
