• Is a return statement mandatory for C++ functions that do not return void?

  - by AlwaysLearning

  My Herb Schildt book on C++ says: "... In C++, if a function is declared as returning a value, it must return a value." However, if I write a function with a non-void return type and do not return anything, the compiler issues a warning instead of an error: "Control reaches end of non-void function." I use gcc (MinGW) and have set the -pedantic flag.

• Saving Data to Registry on Windows 7

  - by Jim Fell

  I heard that Windows 7 restricts access to its registry, so that applications cannot write directly to it. Is this so? I am developing an application in C#, and I would like to be able to save things such as port settings, last file used, etc. between sessions. Is the registry still a good option, or is there another preferred means of doing this now? Thanks.

  I am in the process of setting up a batch script to do a specified action if the script was run on a weekday, and an alternate action if run on the weekend.

• Trying to provide a global logging function

  - by Gekitsuu

  I typically write my scripts with a structure like s #!/usr/bin/python import stuff def do_things(): print "FOO" def main(): do_things() if __name__ == "__main__": main() The problem I have is I'd like to have a logging function that is defined globally and I"m not really sure how to do this. I tried a decorator function but if I define it in main I can't call it from other functions in the script. It seems like something that should be easy to do but not something I have experience with.

• Does the Dalvik file format (*.dx) support more instructions than a Java .class file?

  - by soc

  Is there anything the Dalvik VM supports (in terms of bytecode) which is not used currently because the .class files don't have it? As an example, if people would write their own Source-to-DX converter for their functional language XYZ, would they be able to implement e. g. full tail calls although the .class file does support tail calls only under certain circumstances?
