• Looking for an automated logging tool/library for .NET!

  - by tsocks

  Hello, I'm looking for an library/tool for .NET that logs almost everything that happens in my C# application (Windows Form). The problem is that I'm delivering an application to a client (Windows XP) and after doing some task, that classic Microsoft error window appears: "ApplicationName has encountered a problem and needs to close. We are sorry for the inconvenience" I'm currently handling my application exceptions, but this is something external and I can't get anything from that error, so I would like any automated library that helps me with that. It would work if it logs each line of code executed, orr just log what line was executing before that error appeared, or something that could give me more info about that error. Thank you! P.S: It's a multithreaded application, and have to Timer controls (one for watching a folder every 5secs, and another for watching thread list...). I'm using Windows 7 here and everything seems to work ok.

• Problems updating to Windows 8.1

  - by user52428

  yesterday I attempted to upgrade to windows 8.1 from windows 8. My brother downloaded it on his computer the day before then. I got it from the Windows store. It downloaded and prompted me to restart so I did. It just had the windows 8 loading screen with the HP sign above it, no percentages or anything else, I waited for about 2 hours and while I was waiting I did some research. After reading I saw it could take 20 minutes to an hour to update, but it had already been 2 hours. I read another article and it said someone restarted their computer and it restored to windows 8.0. That's what I did and it worked. So I tried again and the same thing happens, so instead of waiting I decided I would just restart it again. I tried again and this time it showed a percentage it said,"Setting Up" After it reached 100% it went back to what happened before HP sign and just loaded again, I thought it would be different this time because it did show percentages. I waited an hour and nothing happened so I restarted the computer again. This time when I restarted it, it didn't restore, so I turned the laptop of for around 30 minutes turned it back on and it said,"Attempting to restore to previous version of Windows" It said that for around 10 minutes and it restored, so I shut downed my computer for an hour and did some more research, later I found that I needed to update my drivers my drivers we're updated so I did some more research after this I saw I needed to search for updates via: SettingsChange PC settingsWindows Update. It said I already had automatic updates on, I decided to check for updates and it said there was one update scheduled for Saturday. I didn't think this could change anything so I updated what I could. I tried to install it again it was around 11:30 last night when it was done downloading and it prompted me to restart but I had gone to sleep. I woke up today and saw it showed the HP sign and loaded again. I tried restarting it again but this didn't work I had to shut it of for 30 minutes and try again and it worked. So now I'm posting this seeing If I can get any help with this problem. Any help is appreciated. Thanks!

• Alternatives for heapdumps creation with higher performance than jmap?

  - by Christian

  Hi, I have to create heapdumps, which works nice with jmap. My problem is, that jmap takes very long to create the heapdump file. Especially when the heap is getting bigger ( 1GB) it is taking too long. One situation as example: When the server gets into trouble with the heapspace, I want to restart it automatically and create a heapdump before the restart. This works, but takes too long to write the heapdump. This way the server is down for too long. The heapdump creation takes longer than one hour. I know about -XX:+HeapDumpOnOutOfMemoryError, but most of the time I can find the memory problem before the exception is thrown by the jvm. Is there an alternative to jmap which writes the heapdumps faster? A special solution for the example above would also be appreciated. This question is a mix between programming and system-administration, but I think I'm at the right place here.

• Reducing piracy of iPhone applications

  - by Alex Reynolds

  What are accepted methods to reduce iPhone application piracy, which do not violate Apple's evaluation process? If my application "phones home" to provide the unique device ID on which it runs, what other information would I need to collect (e.g., the Apple ID used to purchase the application) to create a valid registration token that authorizes use of the application? Likewise, what code would I use to access that extra data? What seem to be the best available technical approaches to this problem, at the present time? (Please refrain from non-programming answers about how piracy is inevitable, etc.)

  - by abszero

  So here is the basic configuration of the box: Primary RAID 1 (Mirror, Bootable): 2x 300GB WD SATA drives AMD Phenom Quad Core x64 @2.2 ASUS M3N78 Pro Board 4GB RAM Win 7 Ultimate Additionally, this box is a Host OS for several CentOS Boxes via VirtualBox. The box runs like a champ but, for whatever reason, everytime I restart the machine I get a BootMgr not found error when the box tries to boot. I pop in my Win DVD, select 'Repair Windows' then 'Fix Start Up Problems' and everything works fine...once. When I restart the box again I have to go back through this process. Any ideas on what is going on?

• MVVM- How would I go about propagating settings between my main view-model (and other view-models) a

  - by Justin

  I am building a settings dialog for my application and right now all of the settings correspond with settings on the main view-model, but as I add more view's and view-models some may not. I need to know what the best practice is for loading the current settings into the settings dialog and then saving the settings to thier corresponding view-models if the user clicks okay. I will not be using the Properties.Settings.Default system to store settings since I want my application to be as portable as possible and this would store user scoped settings in the directory: C:\Users\ username \Local Settings\Application Data\ ApplicationName Instead of in my application's directory. In case it makes any difference I am using the MVVM Light Toolkit by Laurent Bugnion.

• Mac OS X: All bootcamp options start Windows

  - by Brian Heylin

  I just installed the latest security update on Mac OS X (installed on 2-10-2010). On restart my Mac booted in Windows 7, which I had installed previously and was set not to boot by default. I tried to restart holding the alt key, and selected the Mac OS X partition, but still the Windows 7 partition boots. It does not matter what partition I choose, Windows 7 always boots. I took a look in the OS X partition and noticed that the admin home folder is empty, or at least Windows is not showing any files there. There is another user on OS X and I can see their files no problem. This has me stumped, has anyone any suggestions for a finding a solution?

• Terminal / Panel PC - Single Server Solution: Client/Server or RDP?

  - by StillLearning

  Hi, Our current setup involves a touch screen panel pc with embedded windows, that is connected via network to a server / dedicated pc, within the same physical location. Each of our 'units' has this hardware setup. For a quick resolution we deploy our application to the dedicated pc, and have the panel pc remote desktop to an account which then activates the application. This works but seems a little clunky / rough approach. We did this because the panel pc is rather limited. Now that we have more time, I was wondering if I should separate the application into a gui / application. Deploy the gui logic on the panel pc, and the business/database logic on the dedicated pc. The app is in Java so I was wondering what technology would be best? I was thinking of using RMI, but its not really a client/server app, as there is only one client. Should I stick with RMI, or use Sockets or something else? It will be easy to implement as the application is old, and manually wraps and unwraps data which passes through one class / method call to remote services. All I would have to do is 'RMI' this one method call, and the app will do its own stuff. Cheers.

• How to get php mail function to work on Debian “squeeze”?

  - by Neel Kamal

  I have installed Apache and PHP5 on my debian server. Firstly I tried it using sendmail. Here is the step by step procedure that I have tried : Step 1: apt-get install sendmail Step 2: /etc/init.d/apache2 restart But this didn't work. Then I tried using external SMTP . My domain is registered on BigRock.I registerd an email address there [email protected] and it gave me the required credentials. On server I installed sSMTP > apt-get install ssmtp > Configured "/etc/ssmtp/ssmtp.conf" file. In the configuration file I added [email protected] mailhub=smtp.fostergen.com:587 (Here I have doubt. I am not sure what to use here. I tried smtp.fostergen.com:587, smtp.fostergen.com:25,mx1.mailhostbox.com :587,mx1.mailhostbox.com:25. I am still not sure what to use here mailhostbox.com. I used mx1.mailhostbox.com as it was the mx entry for my domain on bigrock Here is the screenshot![screenshot of bigrock's email management tool] ) hostname=vs3204.ams2.alvotec.de (I entered the command hostname -f on my server and got it as result ) FromLineOverride=YES UseSTARTTLS=YES [email protected] AuthPass=password provided during email registration on bigrock > edited /etc/ssmtp/revaliases (added " root:[email protected]:mx1.mailhostbox.com :587 " in the last line) > edited php.ini file (sendmail_path = /usr/sbin/ssmtp -t) > /etc/init.d/apache2 restart But this didn't work. After this I tried eSMTP. Steps Performed : > apt-get install esmtp > edited /etc/esmtprc hostname=smtp.fostergen.com:587 username= [email protected] password: password provide by bigrock mda="/usr/bin/procmail -d %T" > linked eSMTP to the legacy Sendmail path by execting the command "ln -s /usr/bin/esmtp /usr/bin/sendmail" > edited php.ini file (/usr/bin/sendmail -t -i) > /etc/init.d/apache2 restart But this technique also failed. I just want to send email to users through php mail function. Kindly help. Where I am going wrong?

• Spark View Engine: How to set default master page name?

  - by Dave

  I use Spark View Engine with nested master pages. I have Application.spark which defines the basic layout of the website. Then there are several other masters which themselves use Application.spark as master page (Default.spark, SinlgeColumn.spark, Gallery.spark, ...) If no master page is specified in a view file, then automatically Application.spark is choosen by the Spark View Engine. Since almost all my pages use "Default.spark" as master, is there a way to configure this globally? The other possibilities would be: Set the master in each spark file individually <use master="Default" />. But that's really annoying. Rename my master files (Default.spark <- Application.spark) but that really doesn't make any sense in naming.

  - by siva

  Hi, We have a application which is triggered from browser. This application consumes around 800 mb of memory. This works perfectly when invoked from any browsers in windows OS. The same application when triggered from MacOS throws an out of memory exception which occurs when the application is short of memory. Is there any way to increase the memory allocated for apps running in mac os environment. Also please let me know how JVM arguments can be passed to apps started through java webstart in macOS. Thanks in advance Regards, Siva

• Public Cell ID databases

  - by Alejandro Mezcua

  Hi. I'm building a location aware mobile application which uses GPS, but i'd like to be able to add cell location too. The best thing I have found so far is to use Google Gears, which has a location API available, but my application is not web based. Are there any good public cell id databases that can be accessed from any kind of application? I have found a few interesting projects out there like OpenCellID, but the database is very poor right now.

• TIBRV: Remote vs Local RVD

  - by jsw

  When connected to a local RVD a sending application is shielded from network interruptions and the send message methods will only block for the time it takes for the message to reach the local RVD process. With remote RVD the sending application is no longer shielded from network interruptions and the send message methods will block for the time it takes to hop across the network to reach the remote RVD process. Is my understanding correct? The documentation is vague regarding remote daemons. I'm mostly concerned with how reliable and performant the send message will be from the perspective of a sending application. Introducing unnecessary blocking on the client side due to sending a message (especially a network hop) is a big no-no in this application. The speed at which the messages reach the consumer is not of the utmost importance. With this in mind is a remote RVD out of the question?

• Cocoa - How to copy files to /usr/share?

  - by cyaconi

  Hi all. I'm developing an "installation" like cocoa application wich needs to take care of some http request, some file system reading, copying files to /usr/share, set up cron (not launchd) and ask some information to user. I discarded PackageMaker since I need more flexibility. Currently everything is going well, but on my last installation step, I need to: Delete my previously installed application folder (if exists). It's always the same path: /usr/share/MY_APP Create again the application folder at: /usr/share/MY_APP Copy application files to /usr/share/MY_APP Update a cron job It's very important that /usr/share/MY_APP keeps protected with administrative privileges, so a regular shouldn't delete it. What would be the best approach to implement those steps? BTW, I'm using Xcode 3.2. Thanks a lot! Carlos.

• Working with a Java Mail Server for Testing

  - by Charlie

  I'm in the process of testing an application that takes mail out of a mailbox, performs some action based on the content of that mail, and then sends a response mail depending on the result of the action. I'm looking for a way to write tests for this application. Ideally, I'd like for these tests to bring up their own mail server, push my test emails to a folder on this mail server, and have my application scrape the mail out of the mail server that my test started. Configuring the application to use the mailserver is not difficult, but I do not know where to look for a programatic way of starting a mail server in Java. I've looked at JAMES, but I am unable to figure out how to start the server from within my test. So the question is this: What can I use for a mail server in Java that I can configure and start entirely within Java?

• SharePoint 2010 / ASP.Net Integration - Looking for advice

  - by jpennal

  I have been Googling a problem that I have with trying to integrate the web application that I am working on with SharePoint 2010. The web application is a wiki style tool that allows users to log in via forms authentication or WIA against Active Directory and create content for themselves and others. What we would like to do is to allow a user have a page with the content they have created in our web application mixed in with content that they have living on the SharePoint server. For example, they may want to see a list of documents that they have on the SharePoint server mixed in with some of their content. To accomplish this, we would like to take the credentials the user has logged into our web application with (for example MYDOMAIN\jsmith) and be able to query SharePoint for the documents of that same user (MYDOMAIN\jsmith) WITHOUT the user being prompted to re-enter their credentials to access the SharePoint server (we are trying to avoid the double-hop problem) We have come up with some options for how we want to do this, but we are unsure of what the best approach is. For example, we could - Have a global user, shared by all users to get information we need from SharePoint. The downside is that we cannot filter SharePoint content to a particular user - We could store the users credentials when they log in, but that would only work for users authenticating via forms auth and would be a security issue that some users/clients would not like - Writing a SharePoint extension using WCF to allow us to access the information we need, however we'd still have the issue of figuring out how to impersonate the user we want. Neither of these options are ideal and in our investigation we came across the Claims Authentication/STS option which seems like it is trying to solve the problem we are having. So my question is, based on what I have written, is Claims/STS the best approach for us? We have not been able to find much direction on how to use this method to call into SharePoint from a Web Application and pass along the existing credentials. Does anyone have any experience with any of these issues?

• iPhone SDK Internet connection detection

  - by givp

  I'm working on an iPhone application that makes a few calls to web services. I posted this application on the Apple store but it got rejected (and rightly so) since there was no error message displayed to the user if no Internet connection is available. Since obviously the application would not work without it. So I just wanted to know how to best achieve this? I'm guessing something needs to go in the viewDidLoad method that will throw an alert box saying something like "You need an Internet connection to use this application". Any ideas would be appreciated.

• Mac has become insanely slow : Processes SystemUIServer, UserEventAgent and loginwindow using a lot of memory

  - by SatheeshJM

  I have been using my Mac for for many months without any problem. But recently all of a sudden the Mac became insanely slow. I opened Activity Manager to see what was happening. For three processes SystemUIServer, UserEventAgent and loginwindow, the memory gradually increases and reaches upto 2 GB for each process. This completely hangs up my Mac. I tried the following : 1. Restart Mac 2. Restart Mac in safe mode 3. Manually kill the processes 4. Remove Date and Time from Menu bar(this was supposed to be the problem for the SysteUIServer process's memory according to many users) 5. Removed the externally connected keyboard and mouse(some had suggested this for UserEventAgent's memory) No luck with any of those. The moment I log in, the memory spikes up. Any idea what the hell is happening? Please help.
