• Windows [C++] - Creating new folders if they don't exist for fopen

  - by Gbps

  I have a C++ program that takes user input for fopen in order to initiate a file write. Could someone help me find a function which will return a FILE* and use the Windows specific version of mkdir in order to create the folder structure for fopen to never fail to open a new file in the specified location because one of the folders does not exist. Thanks a bunch!

  - by phjr

  On Mac OS X there is a very useful "open" command which launches an application suitable for opened file type. Is there some C++/Objective-C function on Mac which does the same? Note: I know I could launch an "open" process. I'm just not sure if it's the best option.

• How can i optimize this python code

  - by RandomVector

  def maxVote(nLabels): count = {} maxList = [] maxCount = 0 for nLabel in nLabels: if nLabel in count: count[nLabel] += 1 else: count[nLabel] = 1 #Check if the count is max if count[nLabel] > maxCount: maxCount = count[nLabel] maxList = [nLabel,] elif count[nLabel]==maxCount: maxList.append(nLabel) return random.choice(maxList) nLabels contains a list of integers. The above function returns the integer with highest frequency, if more than one have same frequency then a randomly selected integer from them is returned. E.g. maxVote([1,3,4,5,5,5,3,12,11]) is 5

• Java: Prepare a statement without a connection

  - by r3zn1k

  I'm trying to generate some sql files in my java application. The application will not execute any sql statements, just generate a file with sql statements and save it. I'd like to use the java.sql.PreparedStatement to create my statements so that i don't have to validate every string etc. with my own methods. Is there a way to use the PreparedStatement without the calling java.sql.Connection.prepareStatement(String) function, because I don't have a java.sql.Connection?

• Have a child window be notified when parent window goes to a different page?

  - by Heinrich Schmetterling

  i have a parent window and a child window. in javascript, i want a function in child window to be called whenever the parent window loads a new page. i'd like to use something similar to jQuery's $(document).ready() so that I don't have to worry about whether the parent is done loading yet - but ready() only appears to fire when the window loads the first page - but not when, say, a link is clicked in the parent and it loads a second page. any suggestions? thanks.

• Can a trait state if a C++ class has a default constructor?

  - by Vicente Botet Escriba

  Traits classes can be defined to check if a C++ class has a member variable, function or a type (see here). Curiously, the ConceptTraits do not include traits to check if a C++ class defines a default constructor or given constructor? Can traits be used to check the constructor presence? If yes, how? If not, why it is not possible?
