• Laggy interface with NSSearchField hooked up to an NSArrayController via bindings

  - by Simone Manganelli

  So I've got an NSSearchField hooked up directly to an NSArrayController via bindings, attached to the filterPredicate, so that without any code, the user can just type in the NSSearchField and filter the list of objects in the NSArrayController presented to him in the interface (an NSCollectionView, to be specific). The NSSearchField is hooked up to provide live searching, so that the NSCollectionView is filtered instantly as the user types, not after waiting for a short period for the user to stop typing. However, the problem is that this makes the interface really laggy. Typing is delayed significantly, by 0.5-1 seconds, and it seems like the NSCollectionView is trying to animate each and every rearrangement of items for each portion of the search string that the user enters. What I'd like is for the searching to be live, but the typing in the search field to be fluid, and the results to filter as fast as possible. Is there a way to do this via bindings, or will I need to put in some custom code that triggers the filterPredicate on a separate thread? (Note that I've got a custom sorting algorithm set up on the NSArrayController, and removing it seems to help a bit with the laggyness, but not completely.)

• NSOperations or NSThread for bursts of smaller tasks that continuously cancel each other?

  - by RickiG

  Hi I would like to see if I can make a "search as you type" implementation, against a web service, that is optimized enough for it to run on an iPhone. The idea is that the user starts typing a word; "Foo", after each new letter I wait XXX ms. to see if they type another letter, if they don't, I call the web service using the word as a parameter. The web service call and the subsequent parsing of the result I would like to move to a different thread. I have written a simple SearchWebService class, it has only one public method: - (void) searchFor:(NSString*) str; This method tests if a search is already in progress (the user has had a XXX ms. delay in their typing) and subsequently stops that search and starts a new one. When a result is ready a delegate method is called: - (NSArray*) resultsReady; I can't figure out how to get this functionality 'threaded'. If I keep spawning new threads each time a user has a XXX ms. delay in the typing I end up in a bad spot with many threads, especially because I don't need any other search, but the last one. Instead of spawning threads continuously, I have tried keeping one thread running in the background all the time by: - (void) keepRunning { NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init]; SearchWebService *searchObj = [[SearchWebService alloc] init]; [[NSRunLoop currentRunLoop] run]; //keeps it alive [searchObj release]; [pool release]; } But I can't figure out how to access the "searchFor" method in the "searchObj" object, so the above code works and keeps running. I just can't message the searchObj or retrieve the resultReady objects? Hope someone could point me in the right direction, threading is giving me grief:) Thank you.

• Does cout need to be terminated with a semicolon ?

  - by Philippe Harewood

  I am reading Bjarne Stroustrup's Programming : Principles and Practice Using C++ In the drill section for Chapter 2 it talks about various ways to look at typing errors when compiling the hello_world program #include "std_lib_facilities.h" int main() //C++ programs start by executing the function main { cout << "Hello, World!\n", // output "Hello, World!" keep_window_open(); // wait for a character to be entered return 0; } In particular this section asks: Think of at least five more errors you might have made typing in your program (e.g. forget keep_window_open(), leave the Caps Lock key on while typing a word, or type a comma instead of a semicolon) and try each to see what happens when you try to compile and run those versions. For the cout line, you can see that there is a comma instead of a semicolon. This compiles and runs (for me). Is it making an assumption ( like in the javascript question: Why use semicolon? ) that the statement has been terminated ? Because when I try for keep_terminal_open(); the compiler informs me of the semicolon exclusion.

• Runas Windows Explorer in Windows 7

  - by nsr81

  Hi All, Having a strange issue with Windows Explorer on Windows 7 Professional. When I try to open it up under different user credentials, I get the following error message: Results are the same whether I try it from the context menu or by using runas /user:DOMAIN\User explorer.exe However, if I open up a command prompt (using runas.exe) the behavior is a bit different: typing in just explorer or explorer.exe results in the same error. typing in explorer C: or explorer /E,... doesn't run anything. I'm dropped right back to the prompt. explorer process doesn't start. Has anyone seen this behavior before? If so, how can I go about changing it. Thanks.

• MacBookPro running Windows 7: accidental trackpad input is driving me mad

  - by Ben Hammond

  I am running Windows7 Professional 64bit on a 2010 MacBookPro using BootCamp 3.1. I am using an external trackball. When I am typing, I accidently brushing the trackpad and accidently overtyping randomly selected pieces of text. Which is driving me mad. I have tried to install TrackPad++, but I could not get the Trackpad++ control panel to recognise that the driver software was installed. I tried TrackPad Magic, but although it gives me a system tray icon telling me it is working, but it does not appear to disable the track pad. A quick Google implies that there should be an option in the BootCamp Control Panel 'Ignore accidental Input while typing'. But I can't see one of those in my BootCamp Control Panel. Am I looking in the wrong place? Is this feature 32bit only? Is there anything else I should try?

• Quick access to program shortcut

  - by Nathan DeWitt

  I need to edit a text file on my computer that requires admin access (hosts). I used to do this by hitting WIN and typing "Note". The shortcut for Notepad would show up, and I could right-click and choose Run as Administrator. How do I accomplish the same thing in Windows 8? Notepad isn't something I see pinned to my start menu, and I don't really want to clutter up my menu with something I may use infrequently. I want very quick access to my programs by typing a few letters in the name. If I use WIN-R, I have to know exactly the name of the executable. I want to just type Glob and see options for Sonic Global VPN. And I want to be able to execute that found executable as an admin if I need to. Windows Vista & Windows 7 are excellent at this. Surely this functionality has not been deprecated in Windows 8...

• Wireless Keyboard Intermittent Failure to Type and Added Characters

  - by Kashif

  My keyboard has been acting up from time to time. It's wireless so this may be a wireless issue. What happens is I will be typing and then all of a sudden it seems to stop responding. If I type out this sentence it may show up like so If I ttennnnnnnnn it may ssssssp so While typing that sentence I may have to mash on a key repeatedly to get it to type. The resulting strings of letters seem to be coming as if the keyboard buffer cannot keep up. It's so weird. If I take the USB tranceiver and yank it out then plug it back in, Voila! Problem solved. I did the battery check so that's not a problem. Any suggestions? My keyboard is the Logitech MX3200

• Java application server behind IIS 7.5 on Windows Server 2008

  - by perissf

  I have a Java application server (GlassFish, indeed, but the problem is the same for any other application server, I guess), running on port 8080. And I have IIS 7.5 listening on port 80 as by default configuration. I want to avoid people typing the port because it's unprofessional. So I want that when somebody types http://myserver the traffic is directed to IIS. And this is how it already works now. But I also want that when somebody types http://myserver/java the traffic is directed to port 8080 and consequently my GlassFish splash screen is displayed. If I have deployed an application on GlassFish under context root app1, typing http://myserver/java/app1 should access the application. How can I do this? I have tried with adding some rules with the URL Rewrite utility from IIS7.5 UI, but this shows the port after the rule has rewritten the url, and I want to avoid it.

• Many commands are not found by zsh

  - by Denny Mueller

  If I tab autocomplete, most of the time I get errors. Let's say I do a vim tab to look for the files in the folder. It just jumps to the next command line. Or let's say I press tab after typing rvm use 2.0.0 --default I will get zsh: correct 'rvm' to 'rvim' [nyae]?. If I say no, I get a command not found error. Also if I press tab after typing ruby -v, zsh wants to correct to _ruby -v. Any known bug or any help for this?

• Program broke my windows. Everything randomly minimizes even after multiple restarts

  - by Xitcod13

  I just installed LoL (league of legends) on my computer. The problem is that almost every time after I play the game, it minimizes all my windows which is really annoying. What is worse however is that afterwards other programs do this as well. In the internet browser doesn't minimize but it does loose focus. For example when i type it randomly looses focus and i have to click on the browser window again to it registers my typing. Is there any way to fix this? What can cause such a strange behavior?? In addition this problem persists even after restarting my computer. I previously thought it was internet driver. I no longer think so this happened right after I started playing the game and seems pretty persistent. Please read the comments for further information. This pretty much renders my computer useless. Even typing this takes a huge effort.

• Run a command from Windows 7 Start Menu

  - by Abhijeet Patel

  I'm trying to run commands such as "cmd.exe", "appwiz.cpl" etc by typing it in the Search box of the Start Menu in Windows 7 (x86). I'm able to do this just fine in Vista.

"These files can't be opened. Your internet security settings prevented one or more files from being opened" P.S. - I'm not looking for enabling the "Run" command to show in the Start Menu Any help would be much appreciated

• Disabling the command enter shortcut on Mac Entourage.

  - by Bruce

  It seems like disabling a shortcut should not be such a big deal, but I cannot seem to be able to do it for any shortcuts and specifically not for the combination that I keep hitting by mistake, every single day. The smaller space bar makes it very easy to hit the command key by mistake, and the return is a commonly used key when typing. I keep sending important e-mails before I am done typing, or worse, before I am done editing. I do not necessarily want to disable all the shortcuts, but that one for sure. The choices for changing anything in Entourage seem very limited. [Entourage for Mac 2008. Version 12.2.8. (101117) ESD] It is easy enough just to hit "send." This short cut causes a lot more trouble than it saves. Help.

• Cannot type backquote or backtick in xterm

  - by Cocoro Cara

  Ubuntu 10.10, XTerm(261), Keyboard layout = Canadian Somehow, the backquote (backtick = `) character can't be input does not get entered in XTerm. I type it and nothing happens. The cursor does not move forward. I know it works because I can input it in Terminal (gnome-terminal). The only strange thing is that I have to type the key twice for it to appear. Just to test it, I tried typing it in other applications, and the same thing happens. Have to type it twice in FF, gedit, etc. One more strange thing, I could not input it into this textbox in which I am typing this message. But I can input it in the URL bar, search bar, etc. Someone please help me solve this mystery. I like to use XTerm and I need the backquotes.

• Accessing locally hosted webpage via public IP

  - by Mk12

  Sorry if this is in the wrong place.I don't really know anything about server-related things, but I'm really curious about this. On my mac I figured out how to make a simple web page viewable via the local ip address or computer name on the LAN, and also how to hook it up with a free hostname from dyndns.com. So the dyndns hostname points to something, how can I access it directly? Typing in the global ip address (of the router) doesn't work, but if it did, how would it know which computer to point to? There must be some way of directly accessing what dyndns hostname points to by typing in some number, right? Sorry I don't really understand how it works.

• Notepad++'s pesky EOL Format switching -- how to remove the invisible (default?) keyboard shortcuts Ctrl+M, Ctrl+J

  - by AKE

  Notepad++ lets the user specify whether the end of lines (EOL) format for a file should be entirely in Windows, Unix, or Mac formats. Notepad++ also remember the last one encountered in a file and uses that EOL format when a new file is created. But Notepad++ seems to have some pesky default keyboard shortcuts built-in that can create MIXED format files, creating havoc with this otherwise quite reasonable situation. Specifically: - Ctrl+M puts a Mac style EOL, i.e. (0x0D only), - Ctrl+J puts a UNIX style EOL, i.e. (0x0A only), The hazard is that rapid typing and using the keyboard heavily with other shortcut commands could inadvertantly mean typing oone of these above, each time turning at least one line in the file into another EOL format. So my Question: How can I turn OFF these apparently built-in keyboard shortcuts. Please Note: I've already scanned through Settings > Shortcut Mapper and could not find Ctrl+M or Ctrl+J listed for EOL conversion. Thanks,

• Mapped network drive missing from My Computer and Explorer

  - by matt wilkie

  On a Windows XP Pro SP3 machine one network drive refuses to show up in My Computer or Explorer. The missing drive letter is G:, if that matters. Other mappings work fine. Other profiles one the same machine have no problem seeing G:. I can access the G: just fine typing it into the address bar or in CMD shell. I've used TweakUI to toggle hide/show G: with no difference. TweakUI says G: should be visible. I've logged off,on between toggles to make sure the settings are taking effect. I've looked at reg key [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer] and made sure it's zero'd.ref We've limped along with this broken setup for some time, just working around it, but some applications do not allow typing in a path when choosing a place to save files and it's reached the point where it's intolerable. So, anyone have any idea why XP won't show this drive letter? or how to fix it?

• How to reduce the pain of the command prompt

  - by Adam

  I want to learn to use the command prompt better on Windows to have more control over what I do and just for the learning experience. The main annoyance I have right now is all of the typing. If I want to perform an operation on a file with a large path I'm sitting there typing it out for a minute at least, and if I make a mistake I have to press the up arrow key and scroll through the entire thing and find what I did wrong. Is there any tools to make this easier?

Is there a way to configure CName or S3 bucket such that typing "mydomainname.com" take them to my s3 website ? (I am using Networksolutions as my DNS provider).

• Box Selection and Multi-Line Editing with VS 2010

  - by ScottGu

  This is the twenty-second in a series of blog posts I’m doing on the VS 2010 and .NET 4 release. I’ve already covered some of the code editor improvements in the VS 2010 release.  In particular, I’ve blogged about the Code Intellisense Improvements, new Code Searching and Navigating Features, HTML, ASP.NET and JavaScript Snippet Support, and improved JavaScript Intellisense.  Today’s blog post covers a small, but nice, editor improvement with VS 2010 – the ability to use “Box Selection” when performing multi-line editing.  This can eliminate keystrokes and enables some slick editing scenarios. [In addition to blogging, I am also now using Twitter for quick updates and to share links. Follow me at: twitter.com/scottgu] Box Selection Box selection is a feature that has been in Visual Studio for awhile (although not many people knew about it).  It allows you to select a rectangular region of text within the code editor by holding down the Alt key while selecting the text region with the mouse.  With VS 2008 you could then copy or delete the selected text. VS 2010 now enables several more capabilities with box selection including: Text Insertion: Typing with box selection now allows you to insert new text into every selected line Paste/Replace: You can now paste the contents of one box selection into another and have the content flow correctly Zero-Length Boxes: You can now make a vertical selection zero characters wide to create a multi-line insert point for new or copied text These capabilities can be very useful in a variety of scenarios.  Some example scenarios: change access modifiers (private->public), adding comments to multiple lines, setting fields, or grouping multiple statements together. Great 3 Minute Box-Selection Video Demo Brittany Behrens from the Visual Studio Editor Team has an excellent 3 minute video that shows off a few cool VS 2010 multi-line code editing scenarios with box selection:   Watch it to learn a few ways you can use this new box selection capability to optimize your typing in VS 2010 even further: Hope this helps, Scott P.S. You can learn more about the VS Editor by following the Visual Studio Team Blog or by following @VSEditor on Twitter.

• Is it a "pattern smell" to put getters like "FullName" or "FormattedPhoneNumber" in your model?

  - by DanM

  I'm working on an ASP.NET MVC app, and I've been getting into the habit of putting what seem like helpful and convenient getters into my model/entity classes. For example: public class Member { public int Id { get; set; } public string FirstName { get; set; } public string LastName { get; set; } public string PhoneNumber { get; set; } public string FullName { get { return FirstName + " " + LastName; } } public string FormattedPhoneNumber { get { return "(" + PhoneNumber.Substring(0, 3) + ") " + PhoneNumber.Substring(3, 3) + "-" + PhoneNumber.Substring(6); } } } I'm wondering people think about the FullName and FormattedPhoneNumber getters. They make it very easy to create standardized data formats throughout the app, and they seem to save a lot of repeated code, but it could definitely be argued that data format is something that should be handled in mapping from model to view-model. In fact, I was originally applying these data formats in my service layer where I do my mapping, but it was becoming a burden to constantly have to write formatters then apply them in many different places. E.g., I use "Full Name" in most views, and having to type something like model.FullName = MappingUtilities.GetFullName(entity.FirstName, entity.LastName); all over the place seemed a lot less elegant than just typing model.FullName = entity.FullName (or, if you use something like AutoMapper, potentially not typing anything at all). So, where do you draw the line when it comes to data formatting. Is it "okay" to do data formatting in your model or is that a "pattern smell"? Note: I definitely do not have any html in my model. I use html helpers for that. I'm strictly talking about formatting or combining data (and especially data that is frequently used).

• I want to turn VB.Net Option Strict On

  - by asjohnson

  I recently found out about strong typing in VB.Net (naturally it was on here, thanks!) and am deciding I should take another step toward being a better programmer. I went from vba macros - VB.Net, because I needed a program that I could automate and I never read anything about strong typing, so I kind of fell into the VB.Net default trap. Now I am looking to turn it on and sort out this whole type thing. I was hoping someone could direct me towards some resources to make this transistion as painless as possible. I have read around some and ctype seems to come up a lot, but past that I am at a bit of a loss. What are the benefits of switching? Is there more to it than just using ctype to cast things? I feel like there is a good article that I have failed to come across and any direction would be great. Would a good approach to be to rewrite a program that is written with option strict off and note differences?

• Convert a Row to a Column (or Backwards) in Google Docs Spreadsheets

  - by The Geek

  If you have to deal with a lot of spreadsheets, you’re probably really bored right now. You also might be wondering how to turn a row into a column, or a column into a row. Here’s how to do it with Google Docs Spreadsheets. If you’re an Excel user, you’re also in luck, because we’ve already shown you how to turn a row into a column, or vice-versa. It won’t make you any less bored though. Convert a Row to a Column (or backwards) The first thing you’ll need is a column or a row of information that you want to convert into the opposite. For our example, we’ve got this set of data that we created by using the Auto Fill options in Google Docs. Now in another cell, you’ll need to use the TRANSPOSE function, which you can use by simply typing in the following: =TRANSPOSE( And then selecting the cells with the mouse, or manually typing in the range of cells you want to copy. The final function in this example was: =TRANSPOSE(A1:A11) Finish it off with the final ) character to complete the function, hit the Enter key, and there we are… the column was transposed over to the right. You can use the same thing to turn columns into rows, or rows into columns—just change the range you are looking for.
