• How do I add a static library target that compiles before an application compiles in Xcode?

  - by Koning Baard XIV

  I'm creating a static library in C++. The static library itself links to nothing. To test the static library, I'm creating a test program in C++ (you know, with a main function). Now, I want that whenever I click Build in Xcode, it compiles the static library first, then compiles the test program and link that test program to the static library, like this: # The steps indicate the order Xcode should compile it # (Step 1) Static Library <----------. | (Step 2) Test Program -------> Standard Library Also, the test program should use the header files of the static library. Can anyone explain me how to configure this in Xcode? Thanks

• Running a shellscript from a C++ application and check if it succeeds

  - by Koning Baard

  I am creating an interpreter for my extension to HQ9+, which has the following extra command called V: V: Interpretes the code as Lua, Brainfuck, INTERCAL, Ruby, ShellScript, Perl, Python, PHP in that order, and if even one error has occoured, run the HQ9+-ABC code again most of them have libraries, BF and INTERCAL can be interpreted without a library, but the problem lies in ShellScript. How can I run a shellscript from my C++ application ( =the HQ9+-ABC interpreter) and when it's done, get the error code (0 = succeded, all others = failed)? So something like this: system(".tempshellscript738319939474"); if(errcode != 0) { (rerun code); } can anyone help me? Thanks

• Solving a math problem/expression, which is a string, in PHP

  - by Koning WWWWWWWWWWWWWWWWWWWWWWW

  The user can enter a math problem (expression) like 5 + 654, 6 ^ 24, 2!, sqrt(543), log(54), sin 5, sin(50). After some reformatting (e.g. change sin 5 into sin(5)), and doing an eval, PHP gives me the right result: $problem = "5 + 5324"; eval("$result = " . $problem); echo $problem . " = " . $result; However, this is quite unsafe: /* If you read this, please, plz don't be stupid and DO NOT EXECUTE this code!!!!! */ $problem = "shell_exec('rm -rf /')"; eval("$result = " . $problem); /* Nukes system */ echo $problem . " = " . $result; Can anyone point me in the right direction parsing and solving a math question like the examples above, which is safe? Thanks.

• How can I write a power function myself?

  - by Koning WWWWWWWWWWWWWWWWWWWWWWW

  Since I was 12, I was always wondering how I can make a function which calculates the power (e.g. 23) myself. In most languages these are included in the standard library, mostly as pow(double x, double y), but how can I write it myself? I was thinking about for loops, but it think my brain got in a loop (when I wanted to do a power with a non-integer exponent, like 54.5 or negatives 2-21) and I went crazy ;) So, how can I write a function which calculates the power of a real number? Thanks

  I am new to drawing with Cocoa, and I am making some software which will have sliders similar to these found in GarageBand: These look beautiful and can be controld by moving the mouse up and down. Can you help me with customizing NSSliders by subclassing them, so I can make them look and behave exactly as in GarageBand? Thanks. I have one image for the knob which should be rotated as they do not need to be in 3D .

• Parse string as if it were a querystring in Ruby on Rails

  - by Koning WWWWWWWWWWWWWWWWWWWWWWW

  I have a string like this: "foo=bar&bar=foo&hello=hi" Does Ruby on Rails provide methods to parse this as if it is a querystring, so I get a hash like this: { :foo => "bar", :bar => "foo", :hello => "hi" } Or must I write it myself? EDIT Please note that the string above is not a real querystring from a URL, but rather a string stored in a cookie from Facebook Connect.

• When do you use a circular slider/knob in a good user interface?

  - by Koning Baard

  As I am familiar with some synthesizers, I often user real life circular sliders (e.g. to control the master volume), also called knobs. Like this one: Sometimes I also find these controls in virtual applications (yes I like extreme minimalism =P): But most of them are irritating, confusing or just wrong, and simple sliders could be used instead, making the UI much better. What are the advantages of circular sliders like the one in the screenshot above? And when do you use them? Thanks

• While making an RSS reader which saves articles, how can I prevent duplicates?

  Lets say I have a RSS feed which lists the 3 newest questions on SO. At 1 o'clock, the feed looks like this: While making an RSS reader which saves articles, how can I prevent duplicates? Convert char array to UNICODE in MFC C++ How to deploy a Java Swing application with an embedded JavaDB database? At 2 o'clock, this feed looks like: django url from another template than the one associated with the view-function While making an RSS reader which saves articles, how can I prevent duplicates? Convert char array to UNICODE in MFC C++ (duplicate articles are bold) I want to download the RSS feed every 5 minutes, parse it and save the articles that aren't already saved, but I do not want duplicates (items that remain in the new, updated feed like the examples above). What can I use to determine if an article is already saved? Thanks

• Automatically hide toolbar when it is not in use.

  - by Koning WWWWWWWWWWWWWWWWWWWWWWW

  I am creating a Cocoa Application for Mac OS 10.6 , and I want to hide the toolbar of an NSWindow automatically when it is not in use for at least 30 seconds. I think this can be done with NSTimers, but I'm not familiar with them and I don't know how I can implement this. Another problem is that both the NSToolbarDelegate and NSWindowDelegate protocols don't have delegate methods like toolbarDidShow: Can anyone point me in the right direction? Thanks. PS. This is not to punish the user, but rather give the user a cleaner window (the window consist of only a toolbar for color and font and a text-view). PPS. Can the hide-toolbar-animation lead into a problem with the cursor while the user is typing?

Not just those that are not expired yet. Can anyone help me? Thanks Oh, changing < to > returns no pastes, not even the non-expired ones :(
