• Finite State Machine : Bad design?

  - by f4

  Are Finite State Machines generally considered as bad design in OOP ? I hear that a lot. And, after I had to work on a really old, undocumented piece of C++ making use of it, I tend to agree. It was a pain to debug. what about readability/maintainability concerns?

  I'm making an iPad app and I need to force the orientation to portrait to several parts of the app. I used the undocumented "setOrientation" API and the app was rejected. Is there a documented way to do this?

• Mouse clicks stop working sometimes

  - by AlbertoPL

  I am having a serious issue with my mouse in which it will randomly not be able to click or cause other problems. Here is the breakdown: Sometimes, I can no longer left-click on many of my windows/taskbar (in order to focus them). Even though I can still left click on my desktop icons or the currently active window, I cannot focus any of the others. Other times, when I have a browser open, I will hit to go back one page and it will automatically go forward one page. I know it's a mouse issue because this behavior stops when I unplug the mouse. Things will be fine when I plug the mouse back in, but eventually the behavior starts up again. My mouse is a Razer Diamondback 3G and I am running Windows 7 Professional 32 bit. Any ideas?

• Why is my keyboard acting like the Ctrl key is pressed when I hit an F key?

  - by Dan Tao

  So, I'm gradually getting the hang of the Kinesis Advantage Pro keyboard that my wife bought me for Christmas. I love it so far. But something very strange happened today. (Note: I actually have no idea if this problem has anything to do with the Kinesis keyboard per se. All I know is that I never encountered this problem until after replacing my old keyboard with the Kinesis.) It seems that if I press an F key (e.g., F2), the computer starts acting like I'm holding down the Ctrl key. For example if I click on a link in my web browser, it now opens in a new tab. Or if I hit A all the text in the document I'm editing gets selected. This behavior persists until I manually hit the Ctrl key again. Has anyone seen anything like this before? What could cause such behavior?

• How to delete a user in MSCRM 4.0

  - by Chris Richner

  Do you know of a way to get rid of CRM User accounts in MSCRM 4.0? After some user accounts have been deleted in AD we're faced a lot of issues while importing the organisation to another server stating that there are issues with the user mapping. What kind of idea is behind the fact that no user accounts can be deleted from the crm installation? Is there any tool or undocumented Webservice API call to get rid of crm users? Thanks for sharing yours insights

• IIS: redirect to a webpage if authentication fails

  - by DrStalker

  We have an IIS site (MOSS 2007) that uses Windows Authentication. When a user that has forgotten their password tries to login the servers keeps sending 401 requests. This means on IE the user gets three prompts before IE displays a blank page, on Firefox the user is prompted over and over until they give up. We would like to change the behavior so if a user fails to login three times in a row we send them a redirect to a different site, instead of another 401 Forms authentication is not an option; the site has to remain on windows authentication to allow for SSO capabilities and certain sharepoint functions. Is there any way to tweak the IIS behavior to do this?

• UITableView hide sectionindex but retain sections

  - by Dan Bennett

  We'd like to implement our own section index UI for UITableView. It's clearly possible, since the contacts app does it on iPad. Is there a way of legally hiding the current section index? (I can get to the undocumented _index UIView but that's not going to cut it with Apple I suspect)

• Windows XP waits for usb drive on almost every operation.

  - by Tomasz Kowalczyk

  Hello everyone, I have a problem with my Windows XP operating system, particularly with the USB device that is plugged in - 1TB WD My Book external drive. I haven't found any information about such behaviour when searching in Internet, so I have to ask You. The problem is: when I am using computer, especially during work (programming), when I try to access any information on a hard disk ("internal" one), Windows seems to "consult" it with the external drive. For example, when I open file selection dialog window, if I try to change directory, system activates external drive, reads something (I hear the disk's operational noise) and after some seconds of such pause it makes the operations I requested. There are many situations in which I can reproduce this behavior - opening My Computer, shutting down system, opening partition folder from My Computer - every operation involves the usage of external drive. Please understand me properly - this is not something that happens EVERY time, but at least "many" times a day. What causes such behavior and how can I "turn off" external drive when it's not needed? Thanks in advance for your answers.

• Non-Registry Fix for Secondary Mailboxes Sent Items

  - by Jai Kang

  There is a known issue with Outlook and Exchange where "secondary" mailboxes which are mounted in the same profile, e.g. "John Doe" + CorpMailbox1, CorpMailbox2, CorpMailbox3 will place "sent items" from the secondary mailboxes (e.g. CorpMailbox1) in the user's (e.g. "John Doe") Sent Items folder. There is a registry value (something like DelegateSentItems) to semi-fix this, but I'm looking for an Exchange-side solution. It seems like, at some point, an admin made CC rules to fix this, and for the mailboxes where I see a BCC rule: any item sent to [address] BCC to [address]. The behavior "fixes" the issue, but when I duplicate this work-around for new shared mailboxes, the email ends up in the Inbox and not the Sent Items for the shared mailbox. I don't believe there is any outlook/client-side shenanigans going on, as the intended behavior for the older mailboxes works for new PCs/Users (new imagse) without any Outlook Mailbox Rules.

• Gamma Distribution in Boost

  - by Kamchatka

  Hello, I'm trying to use the Gamma distribution from boost::math but it looks like it isn't possible to use it with boost::variate_generator. Could someone confirm that? Or is there a way to use it. I discovered that there is a boost::gamma_distribution undocumented that could probably be used too but it only allows to choose the alpha parameter from the distribution and not the beta. Thanks!

• Apache2 memory usage when uploading large files

  - by abhaga

  Hi, I am running apache2.2.12 along with PHP 5.2.10. PHP is configured to run as a separate process through fcgid. The problem is that when users upload a file, size of the apache process swells by almost the same amount. So if somebody tries to upload a 200 MB file, one of the child process swells to current size+200 MB. If 2 users simultaneously start uploading, my server crashes. Now it is the virtual memory size which is increasing but since I am on a OpenVZ based VPS, that is what counts. My questions are: Is it the normal Apache behavior or can I do something to fix this? If not, is there a more memory efficient way of handling big file uploads. Going by the current behavior, I will need 1 GB of free RAM for every apache child accepting a upload. Thanks! Abhaya -

• Windows Authentication Website Asking for Credentials

  - by ChrisHDog

  I have a website that has ASP.Net Impersonation Enabled and Windows Authentication Enabled. When navigating to that site using IE8 with "Enable Integrated Windows Authentication" (under Tools - Internet Options - Advanced) checked, the browser pops-up a "Windows Security" dialog box asking for User name and Password. My understanding was that this was automatically passed through and I would not need to type in those details. Additional Information: If I uncheck "Enable Integrated Windows Authentication" I do not get the pop-up window and it appears to work was intended (though that is the opposite of what I would be expecting) If I enable Windows Authentication in Firefox I do not get the pop-up window (i.e. works as intended) Are there some settings or similar that could have been set to create this behavior? Or has anyone else seen similar behavior and know how to fix?

• iTunes command+tab does not bring main window the foreground after command+h

  - by ecoffey

  Related to : Cmd-Tab does not bring iTunes to foreground There people claim that command+h will continue to work, but the behavior I'm seeing is: Launch a full screen Terminal instance (or anything else really) Launch a fresh iTunes command+h to hide it command+tab back to iTunes, this works and the main app window is given focus command+tab to Terminal command+tab to iTunes What I expect to happen: the main iTunes window is brought to the foreground and given focus. What does happen: The application menu bar shows iTunes, but an additional command+` is needed to bring the main app to foreground. I thought it might have been related to a Chrome interaction, since I'm usually commmand+tabbing between my browser and everything else, but that does not seem to be the case. I do have two "plugins" running: last.fm scrobbler Alfred app mini itunes player interface Not sure if either of those create some phantom window or something that is mixing something up. Versions of stuff: OS X: 10.6.5 iTunes: 10.1.1 (4) last.fm: can't find it, but it's recent Alfred: 0.8 (89) So after that big long rant, anyone else seeing this behavior?

• Micro sound breaks/interrupts on Windows 7

  - by cand

  Hello all, I've been experiencing strange behavior recently. When listening to mp3 or watching movie or whatever that uses sound, I get micro breaks in sound. It's like it hangs or cuts a fragment for about 0.5s. When I start OS, it's ok, but as time passes it gets worse, to the extent that music is unlistenable being interrupted every 2 seconds. I haven't found any relevance between this behavior and hardware usage, I don't think it's directly related to HDD (or it might be but with significant delay). I have updated soundcard drivers and it didn't help a lot. My system is Windows 7, computer is simple HP laptop, nx7300-Ru374ES with WD Caviar Scorpio Blue hard drive inside and integrated soundcard on it (I can check the model later if it's important). Did anybody encounter such problem ? Maybe it's a common thing on Windows 7 or someone knows how to solve it? Thanks in advance.

• Why does virtual assignment behave differently than other virtual functions of the same signature?

  - by David Rodríguez - dribeas

  While playing with implementing a virtual assignment operator I have ended with a funny behavior. It is not a compiler glitch, since g++ 4.1, 4.3 and VS 2005 share the same behavior. Basically, the virtual operator= behaves differently than any other virtual function with respect to the code that is actually being executed. struct Base { virtual Base& f( Base const & ) { std::cout << "Base::f(Base const &)" << std::endl; return *this; } virtual Base& operator=( Base const & ) { std::cout << "Base::operator=(Base const &)" << std::endl; return *this; } }; struct Derived : public Base { virtual Base& f( Base const & ) { std::cout << "Derived::f(Base const &)" << std::endl; return *this; } virtual Base& operator=( Base const & ) { std::cout << "Derived::operator=( Base const & )" << std::endl; return *this; } }; int main() { Derived a, b; a.f( b ); // [0] outputs: Derived::f(Base const &) (expected result) a = b; // [1] outputs: Base::operator=(Base const &) Base & ba = a; Base & bb = b; ba = bb; // [2] outputs: Derived::operator=(Base const &) Derived & da = a; Derived & db = b; da = db; // [3] outputs: Base::operator=(Base const &) ba = da; // [4] outputs: Derived::operator=(Base const &) da = ba; // [5] outputs: Derived::operator=(Base const &) } The effect is that the virtual operator= has a different behavior than any other virtual function with the same signature ([0] compared to [1]), by calling the Base version of the operator when called through real Derived objects ([1]) or Derived references ([3]) while it does perform as a regular virtual function when called through Base references ([2]), or when either the lvalue or rvalue are Base references and the other a Derived reference ([4],[5]). Is there any sensible explanation to this odd behavior?

• Python re.IGNORECASE being dynamic

  - by Adam Nelson

  I'd like to do something like this: re.findall(r"(?:(?:\A|\W)" + 'Hello' + r"(?:\Z|\W))", 'hello world',re.I) And have re.I be dynamic, so I can do case-sensitive or insensitive comparisons on the fly. This works but is undocumented: re.findall(r"(?:(?:\A|\W)" + 'Hello' + r"(?:\Z|\W))", 'hello world',1) To set it to sensitive. Is there a Pythonic way to do this? My best thought so far is: if case_sensitive: regex_senstive = 1 else: regex_sensitive = re.I re.findall(r"(?:(?:\A|\W)" + 'Hello' + r"(?:\Z|\W))", 'hello world',regex_sensitive)

• Synergy client drops and reconnects at UAC dialog

  - by sidran32

  I've been using Synergy for a while at work to connect my XP machine (the host) to my Win 7 laptop (the client). I previously was having issues with using Synergy and the UAC prompt, as described in this question, and have had no issues since, until recently. I upgraded to Synergy 1.4.10 and now am seeing odd behavior whenever a UAC prompt appears on my laptop. When the UAC prompt appears on my laptop, Synergy momentarily drops its connection to my laptop, causing my mouse and keyboard focus to revert to my host machine (the XP machine). After about a second or so, though, the connection gets re-established and I am able to type and use the mouse buttons in the UAC prompt. Once the prompt clears, the connection drops again for a second, and then gets re-established again. Is this something to do with configuration or perhaps should I just chalk it up to a change in behavior in version 1.4.10?

• Context menu on Intellj IDEA

  - by Otavio Macedo

  I have installed Intellij IDEA 10 on Linux (Ubuntu 8.04) and the way the context menu works is annoying me. The context menu is visible as long as I keep the right button pressed (if I release the button, the menu disappears). To click on a menu item, I have to position the cursor upon the item with the right button pressed and then release it. I've also figured out two alternative ways to keep the menu visible with the right button released: To right-click, drag, and release the button outside the context menu. Ctrl + Right-click or Shift + Right-click But I would expect the "normal" behavior: that when I right-click and release, the menu keeps visible until the next click (on an item or outside the menu). Is there a way to change this behavior? Thanks in advance.

• Disable automatic Date parsing in HtmlUnit

  - by submonoid

  Having just upgraded to a newer version of HtmlUnit (2.4), I've noticed certain tests are failing when comparing the output of asText. Looking into the differences, this is because dates (present on the page in the format 11/06/2010 00:00z) are being altered in the output to read 2010-06-11. Has anybody else encountered this, and can anybody advise how to turn off this (seemingly undocumented) feature of asText, which seems to go completely against the advised documentation.

• How disable Apple iCal from popping up with every email invite/update?

  - by Sean

  My iCal has new behavior (since upgrading to SL). Every time I get an ical attachment in Mail, the iCal app flies up in my face. I don't see any way to turn off this behavior and it's amazingly disruptive when I'm busy with other activities. Help? EDIT: I want iCal to add the invitations, so when I cmd-tab to the app those items are in the queue awaiting approval. What I am hoping to learn is how to stop the popup action forcing the application to become the top-level window.

• How do I keep the URL in the address bar when stopping page load in Firefox

  - by Peter Jaric

  Suppose I am visiting a page in Firefox and decide to go somewhere else and type the new URL manually into the address field, but the page fails to load, either because it times out, or because I hit Escape. Then Firefox removes my laboriously entered URL and replaces it with the URL of the current page. This is outrageous! I am pretty sure Firefox has changed this behavior lately, because this was one of the reasons I chose Firefox over IE back in the day. How can I turn off this annoying behavior? OS: Windows 7 Firefox version: 22

• How to force a "do you really want to shutdown?" dialog in Windows 7?

  - by Vokuhila-Oliba

  Sometimes I want to choose "Logout current user", but then I hit "Shutdown" by accident. Nearly everywhere else Windows 7 is asking "do you really want to do this? Yes/No" - but that's not the case when I hit the "Shutdown" button. Windows 7 shuts down immediately without giving me the chance to correct my mistake. So I am wondering - why does Windows shut down immediately without asking "really do that?" in this case? Is there a way to change this behavior? For example, could I force Windows to display a dialog asking "Do you really want to shutdown?"? I tried to change this behavior with the policy editor. It seems to be very easy to completely remove the Shutdown button from the Start menu, but I couldn't find an entry to turn on such a Yes/No dialog.
