  • Vista/7 UAC: how to lower process privileges

    - by Sergey
    Hi all, Is it possible for a process to lower itself from elevated UAC permission back to standard user? If not can the elevated process launch its copy with standard user token and then kill itself? Any code examples (C# preferred)? Details: Problem: - user installs my product (written in C#) - the installer elevates its UAC permission to admin - at the end the installer launches my exe - the exe inherits elevated permissions from admin - the exe mounts network drives which become invisible in Windows Explorer (that runs with regular permissions) Options I considered: 1) break installer into outer exe and inner exe, that runs with elevated permission. The install consists of 1000+ lines of NSIS code and I don't know anything about NSIS 2) mounting drives with lower permissions. If I do it Win Explorer can see the drives but my exe cannot 3) setting EnableLinkedConnection registry option to 1. This is a no-go because it requires PC reboot during the installation. Please help! Sergey

  • Books about the philosophy of software development

    - by anon
    The first time I read The Mythical Man Month, I found the book utterly boring, a waste of my time, and thought it was written by some management guru that never wrote a line of code. A few years later, I realized Fred Brooks won the Turing award. Some years after that, after a few large development projects, I started understanding what he was talking about. Are there any other books about software development on a meta/philosophical level—not in the sense of design patterns, templates, or even lisp macros—but at a level where ideas are expressed without code?

  • Best non-development book for software developers

    - by Dima Malenko
    What is the best non software development related book that you think each software developer should read? Note, there is a similar, poll-style question here: What non-programming books should programmers read? Update: Peopleware is a great book, must read, no doubt. But it is about software development so does not count. Update: We ended up suggesting more than one book and that's great! Below is summary (with links to Amazon) of the books you should consider for your reading list. The Design of Everyday Things by Donald Norman Getting Things Done by David Allen Godel, Escher, Bach by Douglas R. Hofstadter The Goal and It's Not Luck by Eliyahu M. Goldratt Here Comes Everybody by Clay Shirky ...to be continued.

  • Doubt about adopting CI (Hudson) into an existing automated Build Process (phing, svn)

    - by maraspin
    OUR CURRENT BUILD PROCESS We're a small team of developers (2 to 4 people depending on project) who currently use Phing to deploy code to a staging environment, before going live. We keep our code in a SVN repo, where the trunk holds current active development and, at certain times, we do make branches that we test and then (if successful), tag and export to the staging env. If everything goes well there too, we finally deploy'em in production servers. Actions are highly automated, but always triggered by human intervention. THE DOUBT We'd now like to introduce Continuous Integration (with Hudson) in the process; unfortunately we have a few doubts about activity syncing, since we're afraid that CI could somewhat interfere with our build process and cause certain problems. Considering that an automated CI cycle has a certain frequency of automatically executed actions, we in fact only see 2 possible cases for "integration", each with its own problems: Case A: each CI cycle produces a new branch with its own name; we do use such a name to manually (through phing as it happens now) export the code from the SVN to the staging env. The problem I see here is that (unless specific countermeasures are taken) the number of branches we have can grow out of control (let's suppose we commit often, so that we have a fresh new build/branch every N minutes). Case B: each CI cycle creates a new branch named 'current', for instance, which is tagged with a unique name only when we manually decide to export it to staging; the current branch, at any case is then deleted, as soon as the next CI cycle starts up. The problem we see here is that a new cycle could kick in while someone is tagging/exporting the 'current' branch to staging thus creating an inconsistent build (but maybe here I'm just too pessimist, since I confess I don't know whether SVN offers some built-in protection against this). With all this being said, I was wondering if anyone with similar experiences could be so kind to give us some hints on the subject, since none of the approaches depicted above looks completely satisfing to us. Is there something important we just completely left off in the overall picture? Thanks for your attention &, in advance, for your help!

  • Chrome plugin process - npapi plugin

    - by kambamsu
    Hi, I'm writing an npapi plugin in Qt. My plugin works perfectly on firefox and opera. The problem in chrome i guess is regarding the "process-per-plugin" setup. What happens is, when i first open a page, the plugin is injected and all works as per expected. But when i navigate from that page to another one, in the new page, the plugin seems to get injected but even its constructor isnt called. To examine the issue, I tried killing my plugin process via the chrome task manager before i navigate to the new page. When i do this, the plugin works as expected in the 2nd page too. I'm unable to comprehend what is happening here. Any help would be appreciated. Thanks

  • Android Development Tips, Tricks & Gotchas

    - by Mat Nadrofsky
    I'm starting down the road of Android Development. At this point I'm looking for some insight from other developers who have been doing 'droid development and have some experience to share with someone who is just starting out. This can be anything from API to AVM to IDE. Any unexpected things come up while building your apps? Any tips for project layout or organization that help facilitate the deployment process to the Android AppStore? Any patterns which specifically helped in a particular situation? Even links to great blogs or sample apps and resources beyond those which you can grab from Google Code would be appreciated.

  • Intellij + GWT 2: Development Mode ignores changes to static content

    - by Kaffeine Coma
    The new Development Mode in GWT 2 is awesome, but unfortunately as launched from Intellij IDEA 9, it does not seem to notice changes made to static files such as html, css, etc. It immediately see changes in *.java files, but not the static ones. If I make a change in a static file I need to quite the Development Mode tool and re-launch it. This is painfully slow, and negates much of the point of using dev mode in the first place I assume this is some artifact resulting from the way the Intellij runner launches it- it creates an out/artifacts/project_war_exploded directory with the static content and class files. How can I get Intellij Dev Mode tool to follow changes made to the original static source files?

  • Which Android phone to use for development...?

    - by Nikos
    Hi, I'm planning to port a couple of games from iPhone/Windows Mobile to the Android platform. The games are written in C++ so I plan to use the NDK with a thin java wrapper. I'm new to the Android platform and need some advice on which phone to buy for development. I suspect like Windows Mobile there is a level of fragmentation with different phones supporting different features (keyboard/ rotation/ screen size/ capacitive touch screen/ etc). What are the best device(s) for development on the Android platform...? They also have to be available in the UK/Europe. Thank you in advance. Nikos.

  • C# File Exception: cannot access the file because it is being used by another process

    - by Lirik
    I'm trying to download a file from the web and save it locally, but I get an exception: C# The process cannot access the file 'blah' because it is being used by another process. This is my code: File.Create("data.csv"); // create the file request = (HttpWebRequest)WebRequest.CreateDefault(new Uri(url)); request.Timeout = 30000; response = (HttpWebResponse)request.GetResponse(); using (Stream file = File.OpenWrite("data.csv"), // <-- Exception here input = response.GetResponseStream()) { // Save the file using Jon Skeet's CopyStream method CopyStream(input, file); } I've seen numerous other questions with the same exception, but none of them seem to apply here. Any help?

  • Python's subprocess.Popen object hangs gathering child output when child process does not exit

    - by Daniel Miles
    When a process exits abnormally or not at all, I still want to be able to gather what output it may have generated up until that point. The obvious solution to this example code is to kill the child process with an os.kill, but in my real code, the child is hung waiting for NFS and does not respond to a SIGKILL. #!/usr/bin/python import subprocess import os import time import signal import sys child_script = """ #!/bin/bash i=0 while [ 1 ]; do echo "output line $i" i=$(expr $i \+ 1) sleep 1 done """ childFile = open("/tmp/childProc.sh", 'w') childFile.write(child_script) childFile.close() cmd = ["bash", "/tmp/childProc.sh"] finish = time.time() + 3 p = subprocess.Popen(cmd, stdout=subprocess.PIPE, stderr=subprocess.PIPE, stdin=subprocess.PIPE) while p.poll() is None: time.sleep(0.05) if finish < time.time(): print "timed out and killed child, collecting what output exists so far" out, err = p.communicate() print "got it" sys.exit(0) In this case, the print statement about timing out appears and the python script never exits or progresses. Does anybody know how I can do this differently and still get output from my child processe

  • Rails Action and Fragment Caching during Development?

    - by viatropos
    I'm just starting to get into Rails caching and am wondering how to test whether or not caching is working in my development environment. I have set these two config variables for both the development (temporarily) and production environments: config.action_controller.perform_caching = true config.action_controller.page_cache_directory = File.join(RAILS_ROOT, 'public', 'cache') And my controller basically looks like this (using the resource_controller gem): class EventsController < Spree::BaseController resource_controller caches_page :index index.response do |format| format.html format.xml { render :xml => @collection.to_xml } end # ... end If I do that, I get these files: public/cache/events.html public/cache/events.xml But when I change caches_page to caches_action, I don't see any generated files and am not sure how to tell if the response has been cached. What do I need to know to know that this is working? I've read the docs and related, the rails caching guides, the railscast, and a few other docs, but I'm still wondering where everything is stored. Thanks!

  • Handling messages for window from other process

    - by MK
    I'm developing a C# WPF application that reparents the main window of another application using a call to Win32 SetParent(). The handle to this out-of-process child window is wrapped by a class named FormHost which is derived from HwndHost. All is working well except for one thing: messages for the reparented window are not delivered to FormHost. MSDN documentation clearly states that the HwndHost window procedure WndProc() cannot be used with out-of-process windows. The alternative, MessageHook doesn't work either. I also tried calling AttachThreadInput() to combine the input processing of the two windows. No luck. Any suggestions?

  • Getting IIS Worker Process Crash dumps

    - by CVertex
    I'm doing something bad in my ASP.NET app. It could be the any number of CTP libraries I'm using or I'm just not disposing something properly. But when I redeploy my ASP.NET to my Vista IIS7 install or my server's IIS6 install I crash an IIS worker process. I've narrowed the problem down to my HTTP crawler, which is a multithreaded beast that crawls sites for useful information when asked to. After I start a crawler and redeploy the app over the top, rather than gracefully unloading the appDomain and reloading, an IIS worker process will crash (popping up a crash message) and continue reloading the app domain. When this crash happens, where can I find the crash dump for analysis?

  • GUI for Build Process

    - by sarah xia
    Hi All, I've just implemented build and deploy process which consists of java files, ant script and cmd files. In the process, a release manager will have to check out source, hit the build.cmd button and then carry a zip file over to a server. I am wondering if it is worthwhile to make a GUI for it? So that the release manager does not need to check out source manually for example? How do I start? I have quite limited knowledge of javax, but I very much like to learn. Thanks, Sarah

  • alternatives to System.Diagnostics.Process.Start when command is too long

    - by Frank Schwieterman
    I have some code which is generating a rather long command that is being sent to System.Diagnostics.Process.Start(). The call fails with a Win32Exception, message "The filename or extension is too long". The path to the program itself is not very long, but the parameters passed in are quite long. I am calling the version where an instance of ProcessStartInfo is passed as the parameter, and in this case its the ProcessStartInfo.Arguments .Field that is very long. (other parameters: CreateNoWindow = true, UseShellExecute = false, RedirectStandardError = true). It looks like the exception is coming from a call to win32 function CreateProcess. Does anyone have an idea of another way to start the process?

  • Process touches behind the UINavigationBar

    - by Reed Olsen
    In my application, I'm displaying a fullscreen image in a 320 x 480 frame. After I display the image, I fade the navigation bar out to allow the user to see the whole picture. When the user taps in the area where the navigation bar was, I would like to bring the navigation bar back. This is very similar to what happens in the iPhone Photos app. Unfortunately, after I've hidden the UINavigationBar, I can't process touches on the screen where the navigation bar once was. I believe this is because the origin of the parent view is right below the navigation bar: How can I process touches in this area to bring the nav bar back?

    Hello all: I'm an iPhone developer, but new to web development. I've done some basic HTML websites and made one in iWeb as well. I'm trying to branch out to actual mobile development now, so I checked out Dashcode. Anyway, I'm trying to put a Call Button, Mail Button, and Map Button in horizontal alignment. I realize that I can add a Column Layout and have two buttons in a row, but that's the most I've gotten. Any ideas? Thanks! Thomas

  • process taking high time on Itanium server

    - by Vishwa
    Hi, we have an application which is recently migrated from PA-Risk server to itanium server. After migration we noticed that there is significant increase in time taken to complete a process. when we tracked the time taken by each part we found that the system time is 7.590000, user time is 3.990000 but elapsed time is 70.434882!! Due to this huge elapsed time, overall performance of the application has gone very low. i wrote a small progrms to perform I/O operations on Itanium. these scripts working faster on Itanium compared to PA-Risk. what could be the reason for this high elapsed time of this process?

  • Useful Java Annotations

    - by Jon
    I'm interested in finding out exactly which Java annotations people think are most useful during development. This doesn't necessarily have to limited to the core Java API, you may include annotations you found in third party libraries or annotations you've developed yourself (make sure you include a link to the source). I'm really interested in common development tasks rather than knowing why the @ManyToOne(optional=false) in JPA is awesome... Include the annotation and a description of why it's useful for general development.
