  • Using new to allocate an array of class elements with an overloaded constructor in C++.

    - by GordoN
    As an example say I have a class foo that does not have a default constructor but one that looks like this foo:foo(int _varA,int _varB) { m_VarA = _varA; m_VarB = _varB; } How would I allocate an array of these. I seem to remember trying somthing like this unsuccessfully. foo* MyArray = new foo[100](25,14). I don't think this will work either. foo* MyArray = new foo[100](25,14) Can this be done? I typically do this by writing the default constructor using some preset values for _varA and _varB. Then adding a function to reset _varA and _varB for each element but that will not work for this case. Thanks for the help.

  • How to use PHP fgetcsv to create an array for each piece of data in csv file?

    - by Olivia
    I'm trying to import data from a csv file to some html code to use it in a graph I have already coded. I'm trying to use PHP and fgetcsv to create arrays for each separate piece of data to use PHP to put it into the html code. I know how to open the csv file and to print it using PHP, and how to print each separate row, but not each piece of data separated by a comma. Is there a way to do this? If this helps, this is the csv data I am trying to import. May 10,72,12,60 May 11,86,24,62 May 12,67,32,34 May 13,87,12,75 May 14,112,23,89 May 17,69,21,48 May 18,98,14,84 May 19,115,18,97 May 20,101,13,88 May 21,107,32,75 I hope that makes sense.

  • Optimise & improve performance of this MYSQL query

  • SQL COUNT records in table 2 JOINS away

    Using MySQL, I have three tables: projects: ID name 1 "birthday party" 2 "soccer match" 3 "wine tasting evening" 4 "dig out garden" 5 "mountainbiking" 6 "making music" batches: ID projectID templateID when 1 1 1 7 days before 2 1 1 1 day before 3 4 2 21 days before 4 4 1 7 days before 5 5 1 7 days before 6 3 5 7 days before 7 3 3 14 days before 8 5 1 14 days before templates: ID message 1 "Hi, I'd like to invite ..." 2 "Dear Sir, Madam, ..." 3 "Can you please ..." 4 "Would you like to ..." 5 "To all dear friends ..." 6 "Does any of you guys ..." I would like to display a table of templates and the number of projects they're used in. So, the result should be: templateID projectCount 1 3 2 1 3 1 4 0 5 1 6 0 I've tried all kinds of SQL queries using various JOINs, but I guess this is too complicated for me. Is it possible to get this result using a single SQL statement?

  • Attributes passed to .build() dont show up in the query

    - by Sebastian
    Hi there guys! Hope your all enjoying your hollydays. Ive run into a pretty funny problem when trying to insert rows into a really really simple database table. The basic idea is pretty simple. The user selects one/multiple users in a multiselect which are supposed to be added to a group. This piece of code will insert a row into the user_group_relationships table, but the users id always @group = Group.find(params[:group_id]) params[:newMember][:users].each do |uid| # For debugging purposes. puts 'Uid:'+uid @rel = @group.user_group_relationships.build( :user_id => uid.to_i ) @rel.save end The user id always gets inserted as null even though it is clearly there. You can see the uid in this example is 5, so it should work. Uid:5 ... SQL (0.3ms) INSERT INTO "user_group_relationships" ("created_at", "group_id", "updated_at", "user_id") VALUES ('2010-12-27 14:03:24.331303', 2, '2010-12-27 14:03:24.331303', NULL) Any ideas why this fails?

  • ActiveX Deployment

    - by balexandre
    We have used for 8 years an ActiveX builder in Delphi and we are now using it on Internet Explorer over the internet (and not on local machine as it was always been the process until here) As today we use this object in the HTML: <object id="ActiveX" classid="CLSID:8EC68701-329D-4567-BCB5-9EE4BA43D358" width="14" height="14"> <param name="tabName" value="AccountPlan"> </object> My question is, what are the viable methods to deploy an Active X Control over HTTP/S, what parameters should I need to append to tell where to find it (http url) and download a new one if newer is available? I got into this article from MSDN Library but refers to VB5.0 and it's dated 1997 ... Just wanna know what can I do now, as probably the tools evolved since last century All help is appreciated, Thank you.

  • Recursive algorithm for coalescing / collapsing list of dates into ranges.

    Given a list of dates 12/07/2010 13/07/2010 14/07/2010 15/07/2010 12/08/2010 13/08/2010 14/08/2010 15/08/2010 19/08/2010 20/08/2010 21/08/2010 I'm looking for pointers towards a recursive pseudocode algorithm (which I can translate into a FileMaker custom function) for producing a list of ranges, i.e. 12/07/2010 to 15/07/2010, 12/08/2010 to 15/08/2010, 19/08/2010 to 20/08/2010 The list is presorted and de-deuplicated. I've tried starting from both the first value and working forwards, and the last value and working backwards but I just can't seem to get it to work. Having one of those frustrating days... It would be nice if the signature was something like CollapseDateList( dateList, separator, ellipsis ) :-)

  • R - Subsetting XTS via Time and Which

    Currently, I have a XTS, called Data, which contains a Date, and two value columns which are numbers. I would like to get a single number as output and which would be the mean of Value1 in the time period from a point where Value2 < mean(Value2) and going forward 14 data points, weeks in this particular data set. In order to get the dates where Value2 < mean(Value2), I wrote the below code Data[which(Data$Value2 < mean(Data$Value2)),"Date"] However, I am not sure how to get the mean of Value1 in the period, going 14 days forward from each of the resultant dates from the above code.

  • How to add values accordingly of the first indices of a dictionary of tuples of a list of strings? Python 3x

    - by TheStruggler
    I'm stuck on how to formulate this problem properly and the following is: What if we had the following values: {('A','B','C','D'):3, ('A','C','B','D'):2, ('B','D','C','A'):4, ('D','C','B','A'):3, ('C','B','A','D'):1, ('C','D','A','B'):1} When we sum up the first place values: [5,4,2,3] (5 people picked for A first, 4 people picked for B first, and so on like A = 5, B = 4, C = 2, D = 3) The maximum values for any alphabet is 5, which isn't a majority (5/14 is less than half), where 14 is the sum of total values. So we remove the alphabet with the fewest first place picks. Which in this case is C. I want to return a dictionary where {'A':5, 'B':4, 'C':2, 'D':3} without importing anything. This is my work: def popular(letter): '''(dict of {tuple of (str, str, str, str): int}) -> dict of {str:int} ''' my_dictionary = {} counter = 0 for (alphabet, picks) in letter.items(): if (alphabet[0]): my_dictionary[alphabet[0]] = picks else: my_dictionary[alphabet[0]] = counter return my_dictionary This returns duplicate of keys which I cannot get rid of.

    I have a table of structures and this structures are 2 dimentional table of constants. can you teach me on how to get the values in the table of constants. (note following is just example) typedef struct { unsigned char ** Type1; unsigned char ** Type2; } Formula; typedef struct { Formula tformula[size]; } table; const table Values = { (unsigned char**) &(default_val1), (unsigned char**) &(default_val2) }; const unsigned char default_val1[4][4] = { {0,1,2,3}, {4,5,6,7}, {8,9,0,11}, {12,13,14,15} } const unsigned char default_val2[4][4] = { {15,16,17,13}, {14,15,16,17}, {18,19,10,21}, {22,23,24,25} }
