• C++: Is it good practice to make getters and setters inline?

  - by Martijn Courteaux

  Hi, The title says it all. public: inline int GetValue() const { return m_nValue; } inline void SetValue(int nNewValue) { this -> m_nValue = nNewValue; } On Learn C++, they said it would run faster. So, I thought it would be great. But maybe, there are some negative points to it.

• How can the crosshair of ginput be restricted to one plot?

  - by Lucas

  I wrote a small MATLAB program with a gui. Inside the gui I have, among other things, a plot in which the user should be able to select two points. For this I use the function ginput, which creates a crosshair for selection. Unfortunatley the crosshair extends the whole window and is not restricted to the plot, which doesn't look nice and is confusing for the user. How can the crosshair be restricted only to the area of the plot?

• Can Visual Studio manage function prototypes for me in C++ header files?

  - by Gibybo

  In C++, the common practice is to declare functions in header files and define them in cpp files. This leads to always having two copies of every function's prototype. Then whenever I want to change a function's name/return value/parameter, I have to manually change it in both files. This seems unnecessarily tedious and there must be lots of people that share my pain, so is there a way to automate these changes between files in VS? Bonus points for vim solutions as well.

• Why is Java layout system so complicated to work with?

  - by Tom Brito

  Some points that make java swing layout system a nightmare: There's thousands of properties; Even if you learn all the properties, each layout manager ignores some properties; The only existing good RAD tool (NetBeans) does not work well; Layout managers behave different with components and containers inside it.

• Find user independent TEMP directory with Java

  - by GHad

  Hi, when running a Java application as service with the user 'LocalService', the temp directory ("java.io.tmpdir") points to 'c:/windows/temp' (for example). Running a Java application normally gives 'c:/documents and settings/user/local settings/temp' instead. How can I determine the user independent temp folder 'c:/windows/temp' when my application runs normally? Thanks and greetings, GHad

• Is there a Mercurial equivalent to gitosis?

  - by fedesilva

  I've used ( and still use ) mercurial and git. I have some repos hosted in a server with gitosis which is great and easy to setup. I am looking for a similar tool for hosting mercurial repos. It must provide minimal acl and ssh access and allow for remote config ( in the style of gitosis's "clone the admin repo and push changes" ). Extra points for automating hgweb config via said tool.

• Scaling vectors from a center point?

  - by user146780

  I'm trying to figure out if I have points that make for example a square: * * * * and let's say I know the center of this square. I want a formula that will make it for eample twice its size but from the center * * * * * * * * Therefore the new shape is twice as large and from the center of the polygon. It has to work for any shape not just squares. I'm looking more for the theory behind it more than the implementation. Thanks

  - by ~konman

  for example: When the MEM CTRLER wants a instruction register to be populated with the DATA which the next ADDR REGISTER points to. Does it send a signal to the ADDR REGISTER to place the next ADDR on the ADDR bus or does the ADDR go to the MEM CTRLER and is placed on the BUS by the MEM CTRLER?

• Help identify the layout used here?

  - by Matt Huggins

  I'm working on a layout that comprises some of the same features seen in the screenshot below, but I'm running into a bit of confusion. Can someone help me understand a few points for the screenshot below? What is the root layout used here? How do I get the button bar to remain at the bottom, while the center section scrolls when it is long enough? Similar to the Ok/Cancel buttons seen here, how do I make them each 50% width (minus some margin and padding)?

• What browser incompatibilities does jquery solve?

  - by pd1138

  I'm currently on the fence about using or not using jquery. I've spent hours researching the pros and cons of using jquery (or any library for that matter). One of the big selling points of jquery is that it frees a developer from worrying about browser incompatibilities. I've tried to find any documentation on exactly which incompatibilities it overcomes. So far I haven't found any. Can anyone help me out with this.

• standard c library for escaping a string.

  - by rampion

  Is there a standard C library function to escape C-strings? For example, if I had the C string: char example[] = "first line\nsecond line: \"inner quotes\""; And I wanted to print "first line\nsecond line: \"inner quotes\"" Is there a library function that will do that transformation for me? Rolling my own just seems a little silly. Bonus points if I can give it a length to escape (so it stops before or beyond the \0).
