• What magical thing could be killing my Drupal session and anywhere from 15-45 minutes of activity?

  - by jini

  I am using a standard Drupal install hosted on a LAMP stack. My settings.php has the following set: ini_set('session.gc_probability', 1); ini_set('session.gc_divisor', 100); ini_set('session.gc_maxlifetime', 200000); ini_set('session.cookie_lifetime', 2000000); my php.ini file has: session.gc_probability = 1 session.gc_divisor = 1000 session.gc_maxlifetime = 1440 Also I have checked that the safe mode is off so that my settings.php file is able to override main php.ini variables. Also since the person can get log out at 15 minutes, it is making me wonder whether php.ini has anything to do with it anyways. I have combed through my code and it seems to work fine on my local host however on server it is having issues. Where else can i possibly check?????

• XAML Binding to property

  - by imslavko

  I have check box in my XAML+C# Windows Store application. Also I have bool property: WindowsStoreTestApp.SessionData.RememberUser which is public and static. I want check box's property IsChecked to be consistent (or binded, or mapped) to this bool property. I tried this: XAML <CheckBox x:Name="chbRemember1" IsChecked="{Binding Mode=TwoWay}"/> C# chbRemember1.DataContext = SessionData.RememberUser; Code for property: namespace WindowsStoreTestApp { public class SessionData { public static bool RememberUser { get; set; } } } But it doesn't seem to work. Can you help me?

• What configure options were used when building gcc / libstdc++?

  - by OK

  After reading about the problem of passing empty std::string objects between DLLs and EXEs, I am concerned about the configure options used to build my gcc / libstdc++. More specific I want to know if --enable-fully-dynamic-string was used during ./configure. I'm using MinGW 4.4.0 on Windows XP. Does anybody know the configuration used to build this release? Is there a general way to find this information for any installation of GNU gcc? The gcc manual gives me no hint on this topic. Thanks for your input!

• Beginner servlet question: accessing files in a .war, which path?

  - by Navigateur

  When a third-party library I'm using tries to access a file, I'm getting "Error opening ... file ... (No such file or directory)" even though I KNOW the file is in the WAR. I've tried both packaged (.war) and "exploded" (directory) deployment, and the file is definitely there. I've tried setting full permissions on it too. It's on Unix (Ubuntu). File is war/dict/index.sense and the error is "dict/index.sense (No such file or directory)". It works fine on my Windows computer when running in hosted mode as a GWT app from Eclipse, just not when I transfer it to the Unix machine for deployment. My question is: has anybody experienced this before and/or are there differences in relative path that I should consider i.e. what's the root path for relative file access in a war?

• Using Ruby to scan through a string

  - by nekosune

  I am trying to create a regex to gather info from strings that look like this: A22xB67-E34... for any number. I have the regex: @spaceCode = "[A-Z]([A-Z0-9][0-9]|[0-9])" @moveCode=/^(?<one>#{@spaceCode})((?<mode>x|\-)(?<two>#{@spaceCode}))+$/ However I get: s="A11-A22xA33".scan(@moveCode) => [["A11", "11", "xA33", "x", "A33", "33"]] which is most definatly NOT what I want. The string could be any length of C22 etc, with either x or - as the seperator, and put it into an array like: ['A22','x',B22','-'.......] Examples: "A22xB23-D23xE25" => ['A22','x','B23','=','D23','E25;] "AA2xA9-A1" => ['AA2','x','A9','-','A1']

• Recommended ways to install USB drivers with a Visual Studio 2005 Setup Project?

  - by tjmoore

  I need to install a USB driver with an application, and I'm using a Visual Studio 2005 Setup Project to create the installer. The driver only needs to be installed sufficient enough so that when the USB device is plugged in, Windows will go off doing it's "installing device" routine and do the rest of the job. It would be okay also to have the setup finish and then the user connects the device when required with the driver install completing then. However the user shouldn't be prompted to find a driver location. The USB drivers I have are available either as plain .sys / .inf files, or as a full installer (.msi together with a setup.exe wrapper). The full installer deals with combinations of operating systems and languages, but the application is for internal use and I can limit the target OS to Windows XP. Would it be better just to run the available installer via a custom action, or to install via the .inf file somehow (I'm not sure how to do that)?

• Writing different structs to a file in C++? [on hold]

  - by user58053

  I need a way to write structures of three different kinds to a binary file, which later has to be searched. (As in, for example, struct A has two fields, an int and a char; struct B has int and a long; I need to output all structures whose int equals the one given from keyboard). I understand how to write structs of the same kind to a file and how to search them, but here I am just lost, best thing I came up with is declaring a struct containing all possibly needed fields and leaving the ones I don't need empty, but it really feels wrong, there HAS to be a better way to do that. I've read about binary files and could not find anything relevant, most examples and tutorials deal with writing one data type. Could anyone point me in the right direction? EDIT: I am looking for what @Jerry_coffin called database mode, and will probably use one of the existing database systems for that, best way to go, probably. Thank you everybody for the suggestions

• MSDN Remark regards Security Descriptors

  - by Doori Bar

  I'm trying to extract and restore a Security Descriptor of a NTFS file, via Windows API - XP SP3, I'm trying to understand which functions are actually able to do it properly, but I simply fail. I found this Remark over MSDN: http://msdn.microsoft.com/en-us/library/aa379573%28VS.85%29.aspx "Some SECURITY_INFORMATION members work only with the SetNamedSecurityInfo function. These members are not returned in the structure returned by other security functions such as GetNamedSecurityInfo..." "Some members..." Which members? Why? "Other Security functions such as..." Which functions? Why? Anybody have any experience with extracting and restoring a security descriptor of a NTFS file? Thanks in advance, Doori Bar

• Spring / Hibernate project with Tomcat and JQuery.

  - by Tiago

  Hi, I have a Dynamic Web Project that implements Spring and Hibernate using a Tomcat Server (v6). I'm lauching Tomcat with my Eclipse Galileo and I'm not getting any errors in the console but Tomcat is rendering my webpages randomly. The page just keep loading but without displaying anything, there's nothing on the console either. When I go in debug mode, it goes throught the right steps, everything seems alright. When I display the source code on the web browser (Firefox latest build) it shows me the right code that is needed to display the page I called. What am I not getting here? Plus when I stop Tomcat, it renders a part of the page. I'm wondering if JQuery could be the problem? The thing is that it's a collaborative project and that the others managed to run the web application in the most alright way. Please, share your experience with me.

• Debug startup program behavior

  - by iceman

  I want to Debug a program called Freecall in my Windows 7 Professional laptop. Now it shows as a Startup item in "System Configuration" console. I tried to uncheck it in the Startup item and restart, but it keeps on adding itself to HKCU\Software|Microsoft\Windows\CurrentVersion\Run. i think its the same for Yahoo messenger..these programs keep on adding to startup even after I manually deleted the entry from the registry. I want to debug and find out if after starting the executable, the program writes to the registry. How can I do that? Is there a way I can run the binary in Sandbox mode? Are there any VS tools for this?

• Why can't my C# app create files in Windows 7?

  - by WindyCityEagle

  I have a C# app that creates a settings file for itself to store the current state of certain visual elements. This app works just fine on any machine that isn't running Windows 7, but on those machines we get an error that the settings file can't be created because the user doesn't have permission. Now, I could fix this issue by going to each computer, logging in as the administrator and giving the user read and write access on the program folder for the application that we've installed, but there has to be a better way. It seems like in XP, you got write access on the folders you created by default, but that isn't the case anymore. Is there a setting I need in the setup package to make this work?

• asp.net global resources problem

  - by Bystrik Jurina

  Hello. I have a weird problem with global resources in my asp.net mvc web application. I have some resources in separate project(not a web app project). Those resources have following settings: Build action: Embedded Resource, Copy To Output Directory: Do not copy, Custom Tool: ResXFileCodeGenerator. When I change an existing value in resource file, build solution in release mode and upload neccesary dll files back to server, the previous values in resources are still shown. However, when I add a new key into resource file, the value of this key is shown properly. I do not have this problem during debugging on localhost. Thanks

• TinyMCE is making my code valid, and I want it to stop! (<img> tag wrapped in <p>)

  - by hookedonwinter

  I have TinyMCE installed on the back end of a site. Some of the html it's accessing isn't totally valid, which I realize is the problem in itself. However, TinyMCE is messing things up by making things valid. I have an <img> with no parents (no <p>, no <div>, etc), and TinyMCE is wrapping the <img> in <p></p>. I'm trying to find a setting that will stop that from happening. Essentially, I want TinyMCE to allow <img> to be it's own element, rather than a child element, if that makes sense. My current settings are: tinyMCE.init({ theme : "advanced", mode : "textareas", relative_urls : false });

• Control ( UIButton, UILable) Hides when the Video plays Again on iPhone!

  - by Taimur Hamza

  Hi, I have displayed UIButton on top of Playing Movie using this code. NSArray *windows = [[UIApplication sharedApplication] windows]; if ([windows count] 1) { // Locate the movie player window UIWindow *moviePlayerWindow = [[UIApplication sharedApplication] keyWindow]; // Add our overlay view to the movie player's subviews so it is // displayed above it. [moviePlayerWindow addSubview:self.myABC]; } There are 2 buttons on top of my movie layer. They play different videos.Now the strange part is the video plays fine with buttons showing on top of it. When i press the button to play the other movie plays but the buttons doesnt show. Seems the view reloads and flushes all the Subviews. But i have checked it in the debug mode and it enters into the 'if' condition and this line runs [moviePlayerWindow addSubview:self.myABC]; But the buttons are not dislpayed. Any ideas wats going wrong ? Thanks, Taimur

• Alternative way to notify the user of an error

  - by Lily

  I have a winform software that communicates with hardware through a protocol. Sometimes error in communication happens and i would like to notify the user. Errors could be for example: timeouts, crc errors, physical disconnection etc... I have a communication window in which i show these errors, but by default this is hidden. The user can open it though the menubar. Popups are annoying to the user (and to myself) so i would like a un-invasive way to notify the user that an error has occurred. Perhaps a info bubble like when XP tells you updates are ready for your computer? I know that NotifyIcon can help put things in the system tray, which i do not wish to have. I'd rather keep it within my MDI. I'm open to other creative ideas as well.

• Can’t dup NilClass - how to trace to offender

  - by fullware

  This exception occurs often and intermittently when in development mode, and appears to get triggered by model associations. Does There are lots of references found by google but none seem to help to trace the problem to an offending class. Does anyone have any insight into how to trace the occurrence of this exception to it's cause? I've seen the posts on adding "unloadable" but I'm not sure I buy it--unless there's a way to trace it somehow to its cause. I'm not in favor of indiscriminately adding such things to every class in hopes the problem might go away. Rails 2.3.5.

• We failed trying database per custom installation. Plan to recover?

  - by Fedyashev Nikita

  There is a web application which is in production mode for 3 years or so by now. Historically, because of different reasons there was made a decision to use database-per customer installation. Now we came across the fact that now deployments are very slow. Should we ever consider moving all the databases back to single one to reduce environment complexity? Or is it too risky idea? The problem I see now is that it's very hard to merge these databases with saving referential integrity(primary keys of different database' tables can not be obviously differentiated). Databases are not that much big, so we don't have much benefits of reduced load by having multiple databases.

• Word filter that groups words?

  - by Legend

  Is there any library that achieves the following: Convert Microsoft Windows 98 Microsoft Windows XP Windows 7 Windows Ultimate Desktop Windows to Windows 4 The complicated part here is to recognize that "Desktop Windows" is an anomaly here and not count it. If nothing is added before the word "Windows", perhaps it can be counted but if there is something else and the suffix does not match any popular suffix, it can still be counted. Maybe I am a little vague here but perhaps someone could have an idea about what I am talking about here. Any suggestions?

• Reserved Memory Addresses?

  - by Nate

  Is there a list of reserved memory addresses out there - a list of addresses that the memory of a user-space program could never be allocated to? I realize this is most likely per-OS or per-architecture, but I was hoping someone might know some of the more common OSes and Arches. I could only dig one up for a few versions of windows: for windows NT,2k and XP that would be: 0x00000000 - 0x0000ffff - lowest page is protected to simplify debugging 0x00001000 - 0x7ffeffff - memory area for your application 0x7fff0000 - 0x7fffffff - protected area to keep memory-functions from damaging the following part 0x80000000 - 0xffffffff - memory where the system including drivers and so on is located Anyone know about for Linux, or BSD (or anything else, for that matter)?

• How to track when my application has unexpectedly shut down?

  - by Vilx-

  I'm writing an application whose purpose involves a lot of logging of different events. Among those I would also like to have an event that the application was shut down - even if unexpectedly like because of a power loss. Naturally, when the power goes out I don't get a chance to write anything anywhere. So my idea was to continuously write a timestamp in some known location (say, once per minute), and when the application was next run, it could determine the approximate time of the unexpected shutdown. A precision of 1 minute would be acceptable for me. However I'm worried that caching at the OS and disk level might interfere with this approach. Is there a better way or if not - how to make sure that the data I just wrote is REALLY written out to the physical medium? Added: Oh, almost forgot the buzzword line: Windows XP and above; .NET 3.5; C#.

• WAMP + Pear installation issue

Is there anyone else who had experienced this slight issue? Thanks!

• 32/64 Bit Question

  - by user48408

  Here's my question. What is the best way to determine what bit architecture your app is running on? What I am looking to do: On a 64 bit server I want my app to read 64 bit datasources (stored in reg key Software\Wow6432Node\ODBC\ODBC.INI\ODBC Data Sources) and if its 32 bit I want to read 32 bit datasources, (i.e. Read from Software\ODBC\ODBC.INI\ODBC Data Sources). I might be missing the point, but I don't want to care what mode my app is running in. I simply want to know if the OS is 32 or 64 bit. [System.Environment.OSVersion.Platform doesn't seem to be cutting it for me. Its returning Win32NT on my local xp machine and on a win2k8 64 bit server (even when all my projects are set to target 'any cpu')]

• How to track down a Blue Screen of Death triggered by an (usermode) application

  - by mhenry1384

  We have a .Net application consisting of mixed managed and unmanaged code. We have a number of reports of users getting BSOD while using our application. These blue screens happen on different versions of Windows. Mostly XP but one user claims it happens on Windows 7. Some users see it happening when doing one thing, other see it happening when doing something completely different. Of course, we cannot reproduce the problem. Needless to say, I'm stumped. A user mode application shouldn't be able to blue screen the OS so we are running into a bug in a common kernel space application, perhaps buggy antivirus software? Does anyone have any tips on how to track something like this down? We don't have access to a computer where this is happening so we wouldn't be able to hook up a kernel debugger or anything like that.

• Getting information about where c++ exceptions are thrown inside of catch block?

  - by tfinniga

  I've got a c++ app that wraps large parts of code in try blocks. When I catch exceptions I can return the user to a stable state, which is nice. But I'm not longer receiving crash dumps. I'd really like to figure out where in the code the exception is taking place, so I can log it and fix it. Being able to get a dump without halting the application would be ideal, but I'm not sure that's possible. Is there some way I can figure out where the exception was thrown from within the catch block? If it's useful, I'm using native msvc++ on windows xp and higher. My plan is to simply log the crashes to a file on the various users' machines, and then upload the crashlogs once they get to a certain size.
