• AllowSetForegroundWindow & SetForegroundWindow: NPAPI plug-in wants to allow a desktop application with no success

  - by David Robert Jones

  Here it's what I have: a web browser plug-in written in C++ and a Windows application written in C#. They communicate through a named pipe. The plug-in instructs the C# application to open a file (suppose that the file is a .txt and it opens in Notepad). Once the C# application is given the command, it opens the file but Notepad doesn't show in the foreground, which isn't acceptable, I must open Notepad in the foreground. I modified the C# application so that it calls the SetForegroundWindow function. This time Notepad didn't open in the foreground, but the taskbar flashes. After reading the documentation for SetForegroundWindow and many articles I think that now I understand what the problem is: the C# application can't bring Notepad to the foreground because it wasn't the the foreground process, the browser was (?). After reading this: "A process that can set the foreground window can enable another process to set the foreground window by calling the AllowSetForegroundWindow function." I decided to modify the plug-in. This time the plug-in calls the AllowSetForegroundWindow function passing ASFW_ANY as a parameter (I know, ASFW_ANY could be risky, but I wanted to make sure that AllowSetForegroundWindow would do it). After I did the modification to the plug-in I tested it and it worked! (Opera 12.02). Then I tested it on Internet Explorer and it worked too. But the problem came when I tested it in Firefox and Chrome. The C# application didn't have the ability to bring Notepad to the foreground. I noticed that for those browsers the AllowSetForegroundWindow function was returning false. So I started investigating and I come to the conclusion that maybe it's because the plugin container that Firefox uses. An idea came to my mind: it worked in Opera 12.02, but they don't have a plugin container, although they did in Opera 12.00. So I downloaded Opera 12.00, I did the test and it failed, which makes me conclude that the plugin container is the culprit. The question is: how can I give to the C# application the ability to set foreground? I don't know how to continue, and I think that I tried all the legitimate ways. The AllowSetForegroundWindow & SetForegroundWindow seems to not apply here.

• 3D Mesh Joining

  - by morlst

  I have 2 (or more) intersecting meshes, which require joining into 1 mesh object. I want to have some control over the resulting seam vertex insertion, so looking to write myself rather than use a library. Has anyone come across some open source code to base the algorithm on / ideas on the process? Initial impressions are: 1. Present in every 3D modelling program - mostly reinventing existing process (hence search for examples) 2. Potential for fiddly-ness around the polygon face direction and just touching conditions. (see above point)

• AppEngine Outage? What's happening?

  - by Albert

  I'm getting a lot of 500 errors recently (both static and dynamic requests). Making my application unavailable. The logs say the following: A problem was encountered with the process that handled this request, causing it to exit. This is likely to cause a new process to be used for the next request to your application. (Error code 121) The same code has been working well for quite some time. What's happening now? I'm using the High Replication Datastore and Python 2.5.

• Detect if an app was uninstalled

  - by mobilekid

  Is there a way to get a system notification when an app has been uninstalled? I would like to maintain a table of all clients' info currently using my app. However, that seems impossible if there is no way to detect this event. The first solution I can think of is to have an always running service in the background listening for android.intent.action.PACKAGE_REMOVED. But then would that service be killed once the uninstallation process has ended, or would it be stopped just before the process has kicked off? Also even if this is a solution it's has the potential to put off a lot of people when they realise that part of the app is running in the background. Any suggestions? Thanks!

• How to know if a PDF contains only images or has been OCR scanned for searching?

  - by Bratch

  I have a bunch of PDF files that came from scanned documents. The files contain a mix of images and text. Some were scanned as images with no OCR, so each PDF page is one large image, even where the whole page is entirely text. Others were scanned with OCR and contain images and searchable text where text is present. In many cases even words in the images were made searchable. I want to make an automated process to recognize the text in all of the scanned documents using OCR, with Acrobat 8 Pro, but I don't want to re-OCR the files that have already been through the OCR process in the past. Does anyone know if there is a way to tell which ones contain only images, and which ones already contain searchable text? I'm planning on doing this in C# or VB.NET but I don't think being able to tell the two kinds of files apart is language dependent.

• Creating folders and uploading a file without using a web browser

  - by Ashpak

  I am using the Java Api We have a web application wherein we want our file to be uploaded on an on_click even on some submit button. We don't want the browser to prompt us to enter the username and password to get the access token. Instead, we can provide the username and the password through the code so that we get the access token and the file will be uploaded directly. Right now, OAuth 2 requires that we enter the username and password to be entered through the browser. Reading through the post, I see that we can authenticate for the first time, obtain a refresh token and then keep on refreshing that token periodically. But our application requirements does not allow for this work-flow. Is there any way to automate the process of entering the user credentials using Java code. or Is there any library that will keep the browser away from the process.

• Software Engineering Component Repository Tool

  - by user320480

  Hello, I'm working as a software engineer for a company. We are going to apply some software engineering standards in our development process. We need a tool which provides a repository for our peripheral products (functions, classes, libraries, ...) which is created during software development process for later use. The tool should provide some functionalities (e.g Name of the component, it's functionality, withing which projects it is used?, author, publication date, list of known bugs, user rating, comment, ...) and it's better to have a web-based interface. Does anybody know such a software?

• Java: How to clear socket bindings

  - by Matt1776

  I am having a few issues with sockets within my Java SIP client. When I bind to an address and port, if something goes wrong I have to attempt to reconnect, usually after I've stopped and restarted the process. Problem with that is then the port is bound and I am forced to increment the local port. How can I remove the binding to the port I am targeting before binding to it? If that isnt possible, then how can I trap the process just before it ends so that I can locate the socket binding and close it manually?

• Reboot windows machines at a certain time of day and automatically login with Python

  - by Tom

  I know how to reboot machines remotely, so that's the easy part. However, the complexity of the issue is trying to setup the following. I'd like to control machines on a network for after-hours use such that when users logoff and go home, or shutdown their computers, whatever, python or some combination of python + windows could restart their machines (for cleanliness) and automatically login, running a process for the night, then in the morning, stop said process and restart the machine so the user could easily login like normal. I've looked around, haven't had too terribly much luck, though it looks like one could do it with a changing of the registry. That sounds like a rough idea though, modifying the registry on a per-day basis. Is there an easier way?

• Why do we need normalized coordinate system? Options

  - by jcyang

  Hi, I have problem understand following sentences in my textbook Computer Graphics with OpenGL. "To make viewing process independent of the requirements of any output device,graphic system convert object descriptions to normalized coordinates and apply the clipping routines." Why normalized coordinates could make viewing process independent of the requirements of any output devices? Isn't the projection coordinates already independent of output device?We only need to first scale and then translate the projection coordinate then we will get device coordinate. So why do we need first convert the projection coordinate to normalized coordinate first? "Clipping is usually performed in normlized coordinates.This allows us to reduce computations by first concatenating the various transformation matrices" Why clipping is usually performed in normlized coordinates? What kind of transformation concatenated? thanks. jcyang.

• How to automate IE/Firefox to download some files from a https: website with Javascript links?

  - by Horace Ho

  Some of my users download several pdf files from an internet website regularly. They'd like to automate the process to save a few minutes every day, and most importantly, to minimize errors. I tried mechanize but failed as mechanize does not process javascripts. Since the download links in the remote site are all triggered by javescript, I am looking for solutions to automate the browser itself. Any recommendations? https remote server login and search are FORM POST file download link are JavaScripts on win32 IE or Firefox thanks!

• Advanced Registry Monitoring

  - by RyanTimmons91

  I'm attempting to create a small utility to watch for the creation (or modification) of a specific registry key, and to kill the process responsible for causing that registry modification. I have had success in watching the changes to the registry via a class called 'RegistryMonitor', however it does not give you any information on what process initiated the registry call, through some googling I found that a library called 'EasyHook' should be able to do what I want, but all the documentation states that its designed for a per-application hook. The program itself is a temporary security patch, until our vendors come out with an official security update. As best I can tell there isn't a way to do exactly what I want to accomplish from C#, which is the only language I can comfortable write, test and execute software in. Any help on this would be appreciated I'm considering watching the registry changes via the program I already have, then if the change is discovered (the pc is already infected) running RKill and locking down the PC to prevent the issue from getting any worse

Some points I realized main problem is client never provide right information at first time and many front end developer works on same project on same CSS so everyone makes his own method sometimes. It increase time of process. Graceful degradation and progressive enhancement both takes time to think and development. should we think about it? it increase the project cost. How to judge time estimation by just seeing a PSD for to make PSD in Cross browser Compatible XHTML CSS. Most of the time I always give less time then then takes more time.

• 2 or more FOR loops in command shell merging fileA line1 with fileB line1, &c.

  Hi, i'm trying to build an ldif import file. I have 2 files, one with the DN and another with the employeeNumber, they match up line for line. Here's the code that does not work: @echo on ::Set BATCH Input Directory set batchdir=e:\Meta ::Set the input file containing the server list set infile=%batchdir%\DDNs3 set infile2=%batchdir%\DDNs4 ::If exists, we remove output file Rm DDNs3.ldif ::For loop below process each line in the input list.

• Using try vs if in python

  - by artdanil

  Is there a rationale to decide which one of try or if constructs to use, when testing variable to have a value? For example, there is a function that returns either a list or doesn't return a value. I want to check result before processing it. Which of the following would be more preferable and why? result = function(); if (result): for r in result: #process items or result = function(); try: for r in result: #process items except TypeError: pass; Related discussion: Checking for member existence in Python

• Writing out to a file in scheme

  - by Ceelos

  The goal of this is to check if the character taken into account is a number or operand and then output it into a list which will be written out to a txt file. I'm wondering which process would be more efficient, whether to do it as I stated above (writing it to a list and then writing that list out into a file) or being writing out into a txt file right from the procedure. I'm new with scheme so I apologize if I am not using the correct terminology (define input '("3" "+" "4")) (define check (if (number? (car input)) (write this out to a list or directly to a file) (check the rest of file))) Another question I had in mind, how can I make it so that the check process is recursive? I know it's a lot of asking but I've getting a little frustrated with checking out the methods that I have found on other sites. I really appreciate the help!

• Getting rails to execute root level file edits on system files without compromising security.

  - by voxobscuro

  I'm writing a Rails 3 application that needs to be able to trigger modifications to unix system config files. I'd like to insulate the file modifications from the consumer side by running them in a background process. I've considered writing out a temp file in rails and then copying the file with a bash script but that doesn't really insulate the system. I've also considered pulling from the database manually with a cron based script and updating the configs. But what I would really like is a component that can hook into the rails environment, read out what is needed from the database, and update the config files. This process needs to be run as root because the config files mostly live in /etc/whatever. Any suggestions? Thanks!

• debate: Is adding third party libraries to a war a good idea?

  - by Master Chief

  We have a debate going on . a. The "standard" way of assembling a web app. Create a WAR with all our app artifacts and all other components like hibernate and memcached etc are deployed in the tomcat/shared/lib area. b. Create a humongous war with everything included and nothing in tomcat/shared/lib. Pros for a - It keeps things modular and the war is small. Cons for a - dependency on shared/lib has to be managed especially by the deployment process. Pros for b - All dependencies are controlled by the build process removing any room for error. Cons for b - War is really, really big. If you are deploying over a network to a huge farm, then it might have an impact. want to see what thoughts others might have about this.
