• How can I create a separate toolbar from the Task Bar?

  - by Iszi

  In Windows XP, you could separate toolbars from the Task Bar by dragging them to the desktop. They could then be left lying about anywhere on your screen or, my preferred option, docked to any side of the screen. I found this particularly useful to keep a handy list of common phone numbers quickly accessible. I'd create a new toolbar pointing to a custom folder, and put a bunch of dead shortcuts in the folder that had names and numbers as their file names. I'd then dock the toolbar to the left side, set it to auto-hide and always on top (options which could be set separate from the Task Bar as well) and it would be readily available no matter what else I was doing on my system. However, on my Windows 7 system, I seem unable to perform the crucial step of pulling the new toolbar off of the Task Bar. This is of course with the Task Bar "unlocked" so that I can move all my toolbars around. Is there something I'm missing here, or is this a feature that's been disabled in Windows 7? Is there any way to re-enable it, or otherwise achieve similar functionality? I'd rather be able to do this without additional software, if possible.

• RESTfully Nesting Resource Routes with Single Identifiers

  - by Craig Walker

  In my Rails app I have a fairly standard has_many relationship between two entities. A Foo has zero or more Bars; a Bar belongs to exactly one Foo. Both Foo and Bar are identified by a single integer ID value. These values are unique across all of their respective instances. Bar is existence dependent on Foo: it makes no sense to have a Bar without a Foo. There's two ways to RESTfully references instances of these classes. Given a Foo.id of "100" and a Bar.id of "200": Reference each Foo and Bar through their own "top-level" URL routes, like so: /foo/100 /bar/200 Reference Bar as a nested resource through its instance of Foo: /foo/100 /foo/100/bar/200 I like the nested routes in #2 as it more closely represents the actual dependency relationship between the entities. However, it does seem to involve a lot of extra work for very little gain. Assuming that I know about a particular Bar, I don't need to be told about a particular Foo; I can derive that from the Bar itself. In fact, I probably should be validating the routed Foo everywhere I go (so that you couldn't do /foo/150/bar/200, assuming Bar 200 is not assigned to Foo 150). Ultimately, I don't see what this brings me. So, are there any other arguments for or against these two routing schemes?

• autotools: no rule to make target all

  - by Raffo

  I'm trying to port an application I'm developing to autotools. I'm not an expert in writing makefiles and it's a requisite for me to be able to use autotools. In particular, the structure of the project is the following: .. ../src/Main.cpp ../src/foo/ ../src/foo/x.cpp ../src/foo/y.cpp ../src/foo/A/k.cpp ../src/foo/A/Makefile.am ../src/foo/Makefile.am ../src/bar/ ../src/bar/z.cpp ../src/bar/w.cpp ../src/bar/Makefile.am ../inc/foo/ ../inc/bar/ ../inc/foo/A ../configure.in ../Makefile.am The root folder of the project contains a "src" folder containing the main of the program AND a number of subfolders containing the other sources of the program. The root of the project also contains an "inc" folder containing the .h files that are nothing more than the definitions of the classes in "src", thus "inc" reflects the structure of "src". I have written the following configure.in in the root: AC_INIT([PNAME], [1.0]) AC_CONFIG_SRCDIR([src/Main.cpp]) AC_CONFIG_HEADER([config.h]) AC_PROG_CXX AC_PROG_CC AC_PROG_LIBTOOL AM_INIT_AUTOMAKE([foreign]) AC_CONFIG_FILES([Makefile src/Makefile src/foo/Makefile src/foo/A/Makefile src/bar/Makefile]) AC_OUTPUT And the following is ../Makefile.am SUBDIRS = src and then in ../src where the main of the project is contained: bin_PROGRAMS = pname gsi_SOURCES = Main.cpp AM_CPPFLAGS = -I../../inc/foo\ -I../../inc/foo/A \ -I../../inc/bar/ pname_LDADD= foo/libfoo.a bar/libbar.a SUBDIRS = foo bar and in ../src/foo noinst_LIBRARIES = libfoo.a libfoo_a_SOURCES = \ x.cpp \ y.cpp AM_CPPFLAGS = \ -I../../inc/foo \ -I../../inc/foo/A \ -I../../inc/bar And the analogous in src/bar. The problem is that after calling automake and autoconf, when calling "make" the compilation fails. In particular, the program enters the directory src, then foo and creates libfoo.a, but the same fail for libbar.a, with the following error: Making all in bar make[3]: Entering directory `/user/Raffo/project/src/bar' make[3]: *** No rule to make target `all'. Stop. I have read the autotools documentation, but I'm not able to find a similar example to the one I am working on. Unfortunately I can't change the directory structure as this is a fixed requisite of the project I'm working on. I don't know if you can help me or give me any hint, but maybe you can guess the error or give me a link to a similar structured example. Thank you.

• How can I shrink the Address toolbar in the Task Bar?

  - by Iszi

  I like being able to run commands straight from my Task Bar. So, I've enabled the Address toolbar on my new Windows 7 system - just like I had on my old XP system. However, the bar seems to have a mandatory minimum length that's a bit longer than I'd prefer. It's about twice as long, if memory serves, as the minimum size allowed in XP. Is there any way I can adjust this minimum length, through a Registry key or some other means? (Note: I've also got a related question, about removing the Refresh button at the end of the bar.) EDIT: For clarity, I'm adding a screenshot. The toolbar I want to shorten is the one circled below, with an empty text-entry field that has a drop-down and "Refresh" button. I currently have it positioned between a Quick Launch toolbar and the Taskbar. On the far side of the Taskbar, before the System Tray, is a Desktop toolbar.

• How can I slightly delay the pop up of the task bar?

  - by Xavierjazz

  Windows XP SP3 Many times as I head to the bottom of my desktop, I will slightly overshoot the target at the bottom and the task bar will pop up, hiding the target. I then have to move the cursor out of it so it retreats and then again try to access the target. Is there a way to add an interval, say, 1 second, to the task bar popping up so I can adjust to the target before the task bar covers it? EDIT: as per my answer below, "What I ended up doing is just docking it on the LH side of the screen. There is no change in response but I don't go to that location so often so it's much better.".

• In Windows, a batch file with a recursive for loop and a file name including blanks

  - by uvts_cvs

  Hello, I have a folder tree, like this (it's only an example, it will be deeper in my real case): C:\test | +---folder1 | foo bar.txt | foobar.txt | +---folder2 | foo bar.txt | foobar.txt | \---folder3 foo bar.txt foobar.txt My files have one or more spaces in the name and I need to perform a command on them, so I am interested in foo bar.txt but not in foobar.txt. I tried (inside a batch file): for /r test %%f in (foo bar.txt) do if exist %%f echo %%f where the command is the simple echo. It does not work because the space is skipped and I get no output. This works but it is not what I need: for /r test %%f in (foobar.txt) do if exist %%f echo %%f It prints: C:\test\folder1\foobar.txt C:\test\folder2\foobar.txt C:\test\folder3\foobar.txt I tried using the quotation mark (") but it does not work: for /r test %%f in ("foo bar.txt") do if exist %%f echo %%f It does not work because the quotation mark is still included in the output: C:\test\folder1\"foo bar.txt" C:\test\folder2\"foo bar.txt" C:\test\folder3\"foo bar.txt"

• Why doesn't disabling IE's 'Protected Mode' enable the dragging-and-dropping of addresses from the IE address bar into Notepad

  - by dumbledad

  IE's Protected Mode prevents one dragging the address from the IE address bar into other applications (for example Notepad). There's an informative article on MSDN about Allowing Drag and Drop Operations in your Application. If I uncheck Enable Protected Mode in IE's settings and restart IE I still cannot drag the address from the IE address bar into other Notepad. Why doesn't disabling IE's 'Protected Mode' enable the dragging-and-dropping of addresses from the IE address bar into Notepad? Is there a way to make that work without adding a registry entry for Notepad (following the instructions in the article I mentioned)? (N.B. This is actually part of me trying to work out how to get this address drag-and-drop working in Processing.)

• How to get a tool window title bar height in WPF ?

  - by user275587

  WPF includes the title bar height in the total window height instead of using only the client content area height. Is there a way to disable this behaviour? If not, how can I get the height of a tool window title bar? I'm aware of the SystemParameters.CaptionHeight property and the SystemParameters.WindowCaptionHeight property but they both return the height of a regular window title bar. This is not the correct value for a tool window because the title bar is smaller for this type of window. I need something like SystemParameters.ToolWindowCaptionHeight Thanks.

• Is it possible to change the border color of a UISearchDisplayController's search bar?

  - by prendio2

  I have a UISearchBar added as my table header with the following code. searchBar = [[UISearchBar alloc] initWithFrame:self.tableView.bounds]; searchBar.tintColor = [UIColor colorWithWhite:185.0/255 alpha:1.0]; [searchBar sizeToFit]; self.tableView.tableHeaderView = searchBar; Then I set my UISearchDisplayController up as follows. searchDisplayController = [[UISearchDisplayController alloc] initWithSearchBar:searchBar contentsController:self]; [searchDisplayController setDelegate:self]; [searchDisplayController setSearchResultsDataSource:self]; Everything functions as I would like except that the UISearchDisplayController has added a blue(ish) border above the search bar — this bar does not recognise the tintColor I have set on the search bar. Is it possible to change the color of this bar? It is obviously not absolutely crucial but that line is going to bug me forever if it stays blue like that!

• Git: can't undo local changes (error: path ... is unmerged)

  - by mklhmnn

  I have following working tree state $ git status foo/bar.txt # On branch master # Unmerged paths: # (use "git reset HEAD <file>..." to unstage) # (use "git add/rm <file>..." as appropriate to mark resolution) # # deleted by us: foo/bar.txt # no changes added to commit (use "git add" and/or "git commit -a") File foo/bar.txt is there and I want to get it to the "unchanged state" again (similar to 'svn revert'): $ git checkout HEAD foo/bar.txt error: path 'foo/bar.txt' is unmerged $ git reset HEAD foo/bar.txt Unstaged changes after reset: M foo/bar.txt Now it is getting confusing: $ git status foo/bar.txt # On branch master # Changes to be committed: # (use "git reset HEAD <file>..." to unstage) # # new file: foo/bar.txt # # Changed but not updated: # (use "git add <file>..." to update what will be committed) # (use "git checkout -- <file>..." to discard changes in working directory) # # modified: foo/bar.txt # The same file in both sections, new and modified? What should I do? Thanks in advance.

• Exclude first child with XSL-T

  - by zneak

  Hello, What I'm trying to do is fairly simple, but I can't find the way to. I just want to iterate over the children of a node excluding the first child. For instance, in this XML snippet, I would want all the <bar> elements, except the first one: <foo> <Bar>Example</Bar> <Bar>This is an example</Bar> <Bar>Another example</Bar> <Bar>Bar</Bar> </foo> There is no common attribute by which I can filter (like an id tag or something similar). Any suggestions?

• How do you link to an action that takes an array as a parameter (RedirectToAction and/or ActionLink)

  - by Andrew

  I have an action defined like so: public ActionResult Foo(int[] bar) { ... } Url's like this will work as expected: .../Controller/Foo?bar=1&bar=3&bar=5 I have another action that does some work and then redirects to the Foo action above for some computed values of bar. Is there a simple way of specifying the route values with RedirectToAction or ActionLink so that the url's get generated like the above example? These don't seem to work: return RedirectToAction("Foo", new { bar = new[] { 1, 3, 5 } }); return RedirectToAction("Foo", new[] { 1, 3, 5 }); <%= Html.ActionLink("Foo", "Foo", new { bar = new[] { 1, 3, 5 } }) %> <%= Html.ActionLink("Foo", "Foo", new[] { 1, 3, 5 }) %> However, for a single item in the array, these do work: return RedirectToAction("Foo", new { bar = 1 }); <%= Html.ActionLink("Foo", "Foo", new { bar = 1 }) %> When setting bar to an array, it redirects to the following: .../Controller/Foo?a=System.Int32[] Finally, this is with ASP.NET MVC 2 RC. Thanks.

• How to change web browser's tab bar background color or image?

  - by Hanynowsky

  Running Precise. I am tweaking the ambiance theme to my taste.

• Ruby &&= edge case

  - by Alan O'Donnell

  Bit of an edge case, but any idea why &&= would behave this way? I'm using 1.9.2. obj = Object.new obj.instance_eval {@bar &&= @bar} # => nil, expected obj.instance_variables # => [], so obj has no @bar instance variable obj.instance_eval {@bar = @bar && @bar} # ostensibly the same as @bar &&= @bar obj.instance_variables # => [:@bar] # why would this version initialize @bar? For comparison, ||= initializes the instance variable to nil, as I'd expect: obj = Object.new obj.instance_eval {@foo ||= @foo} obj.instance_variables # => [:@foo], where @foo is set to nil Thanks!

• When clicking below window title bar in KDE, window dragging is initiated. Can I change this behavior?

  - by hdpq

  this one is regarding KDE in Ubuntu 12.04. The thing is that whenever I click below the window title bar in KDE, the window manager always assumes I want to drag the window, not just activate it. Clicking the title bar activates the window without dragging it just fine, however I sometimes find it hard to click because it's rather narrow :) Is there any way to change this behavior (besides the obvious "make your title bar larger" thing)? I also assume this is happening to Gtk applications only (Firefox, Thunderbird, Synaptic), as I have tried it with several KDE apps (KWrite, KTorrent, Gwenview, Konsole) and noticed no such behavior. Thanks in advance!

• Do we set the bar too high by requiring that code tests not suffer from buffer overflow?

  - by brice

  We are currently recruiting for a Junior Developer position working mainly in C on Linux. As part of the process, we require candidates to complete a code test at their leisure in C. So far we have rejected two candidates on the basis that their code, although readable and in one case rather idiomatic, suffered from buffer overflow errors due to unbounded buffer writes. Are buffer overflows acceptable from a graduate developer? Are we setting the bar too high? What is the expected capability of graduate/Junior engineers? [Edit]: We explicitly ask for error-checked, production quality code. We provide a test & build framework for the candidates

• What user-friendly term should I use for a view that lives under a tab in a tab bar app?

  - by Emile Cormier

  My app uses a tab bar controller. In the user documentation, I'm not sure what name to use for a view that lives under a tab. For example, the app has a Settings tab. In the user documentation, I have a sentence that goes something like this: This threshold can be adjusted in the Settings tab. "Settings tab" is not terribly user-friendly. What would be a better term than "tab"? I've looked though Apple's Human Interface Guideline, but I can't find what would be the official user-friendly term for "view that lives under a tab".

• Why does my health bar disappear whenever my character takes amage?

  - by iQue

  Im making health bar for my game that looks like this: public void healthBar(Canvas canvas) { float healthScale = happy.getHP() / happy.getMaxHP(); Rect rect = new Rect(20, 20,(120 * (int)healthScale), 40); Paint paint = new Paint(); paint.setColor(Color.RED); canvas.drawRect(20, 20, 220 * healthScale, 40, paint) } this is called every time my game renders. When the game starts it's where I want it, but as soon as my character (happy) takes any damage, it dissapears. And I know that his hp only gets subtracted by 5 every time he gets hit. So this should not happen? example: @Startup: happy.getHP() == 100, happy.getMaxHP == 100. when damaged HP -=5, -> happy.getHP() == 95 -> healthscale == 0,95 -> 220 * 0,95 == new width for Rect(?)

• Same Title Bar but different View below it in Android?

  - by sunil

  Hi, In one of my Android Application I need to keep the title bar same but the view that is shown in the rest of the screen changes. So, I have taken different Activity for all the views that I need to show and set the title bar in every Activities onCreate method. Now, the problem is that I have a button in the title bar and need to perform certain action on its click event. Writing the same event handling code in every Activity class is very cumbersome. Is there any other way out that whenever there is a click event on that button of the title bar then we can have the same functionality without writing the same code in all the Activity classes. Can we use ViewGroup for that? I don't have much idea about ViewGroup. Is that possible with ViewGroup? If anyone knows the solution then please let me know. Thanks & Regards Sunil

• Efficiently retrieve objects with one to many references in Grails using GORM

  - by bebeastie

  I'm trying to determine how to find/retrieve/load objects efficiently in terms of a.) minimizing calls to database and b.) keeping the code as elegant/simple as possible (i.e. not writing hql etc.). Assume you have two objects: public class Foo { Bar bar String badge } public class Bar { String name } Each Foo has a bar and a badge. Also assume that all badges are unique within a bar. So if a Foo has a badge "4565" there are no other Foos that have the same badge # AND the same bar. If I have a bar ID, how can I efficiently retrive the Foo w/o first selecting Bar? I know I can do this: Foo.findByBadgeAndBar("4565", Bar.findById("1")) But that seems to cause a select on the Bar table followed by a select on the Foo table. In other words, I need to produce the Grails/Hibernate/GORM equivalent of the following: select * from foo where badge="4565" and bar_id="1"

• Custom class object in Initialization list

  - by Michael

  I have a class Bar: class Bar { public: Bar(void); ~Bar(void); }; And a class Foo that gets a reference to Bar object as a constructor parameter and needs to save it in a private member bar_ : class Foo { private: Bar& bar_; public: Foo(Bar& bar) : bar_(bar) {} ~Foo(void) {} }; This doesn't compile : overloaded member function not found in 'Parser' missing type specifier - int assumed. Note: C++ does not support default-int Now i suspect couple of things that i need to assure, the second error is for Bar& bar_; declaration in Foo. Do i need to use an explicit constructor when declaring bar_ ? I am interested in learning how the compiler works regarding this matter, so a detailed explanation would be highly appreciated. Thanks.
