• C++ How to deep copy a struct with unknown datatype?

  - by Ewald Peters

  hi, i have a "data provider" which stores its output in a struct of a certain type, for instance struct DATA_TYPE1{ std::string data_string; }; then this struct has to be casted into a general datatype, i thought about void * or char *, because the "intermediate" object that copies and stores it in its binary tree should be able to store many different types of such struct data. struct BINARY_TREE_ENTRY{ void * DATA; struct BINARY_TREE_ENTRY * next; }; this void * is then later taken by another object that casts the void * back into the (struct DATA_TYPE1 *) to get the original data. so the sender and the receiver know about the datatype DATA_TYPE1 but not the copying object inbetween. but how can the intermidiate object deep copy the contents of the different structs, when it doesn't know the datatype, only void * and it has no method to copy the real contents; dynamic_cast doesn't work for void *; the "intermediate" object should do something like: void store_data(void * CASTED_DATA_STRUCT){ void * DATA_COPY = create_a_deepcopy_of(CASTED_DATA_STRUCT); push_into_bintree(DATA_COPY); } a simple solution would be that the sending object doesn't delete the sent data struct, til the receiving object got it, but the sending objects are dynamically created and deleted, before the receiver got the data from the intermediate object, for asynchronous communication, therefore i want to copy it. instead of converting it to void * i also tried converting to a superclass pointer of which the intermediate copying object knows about, and which is inherited by all the different datatypes of the structs: struct DATA_BASE_OBJECT{ public: DATA_BASE_OBJECT(){} DATA_BASE_OBJECT(DATA_BASE_OBJECT * old_ptr){ std::cout << "this should be automatically overridden!" << std::endl; } virtual ~DATA_BASE_OBJECT(){} }; struct DATA_TYPE1 : public DATA_BASE_OBJECT { public: string str; DATA_TYPE1(){} ~DATA_TYPE1(){} DATA_TYPE1(DATA_TYPE1 * old_ptr){ str = old_ptr->str; } }; and the corresponding binary tree entry would then be: struct BINARY_TREE_ENTRY{ struct DATA_BASE_OBJECT * DATA; struct BINARY_TREE_ENTRY * next; }; and to then copy the unknown datatype, i tried in the class that just gets the unknown datatype as a struct DATA_BASE_OBJECT * (before it was the void *): void * copy_data(DATA_BASE_OBJECT * data_that_i_get_in_the_sub_struct){ struct DATA_BASE_OBJECT * copy_sub = new DATA_BASE_OBJECT(data_that_i_get_in_the_sub_struct); push_into_bintree(copy_sub); } i then added a copy constructor to the DATA_BASE_OBJECT, but if the struct DATA_TYPE1 is first casted to a DATA_BASE_OBJECT and then copied, the included sub object DATA_TYPE1 is not also copied. i then thought what about finding out the size of the actual object to copy and then just memcopy it, but the bytes are not stored in one row and how do i find out the real size in memory of the struct DATA_TYPE1 which holds a std::string? Which other c++ methods are available to deepcopy an unknown datatype (and to maybe get the datatype information somehow else during runtime) thanks Ewald

• Fast file search algorithm for IP addresses

  - by Dave Jarvis

  Question What is the fastest way to find if an IP address exists in a file that contains IP addresses sorted as: 219.93.88.62 219.94.181.87 219.94.193.96 220.1.72.201 220.110.162.50 220.126.52.187 220.126.52.247 Constraints No database (e.g., MySQL, PostgreSQL, Oracle, etc.). Infrequent pre-processing is allowed (see possibilities section) Would be nice not to have to load the file each query (131Kb) Uses under 5 megabytes of disk space File Details One IP address per line 9500+ lines Possible Solutions Create a directory hierarchy (radix tree?) then use is_dir() (sadly, this uses 87 megabytes)

• Plot 2 graphs in same plot in R?

  - by Sandra Schlichting

  I would like to plot y1 and y2 in the same plot. x <- seq(-2, 2, 0.05) y1 <- pnorm(x) y2 <- pnorm(x,1,1) plot(x,y1,type="l",col="red") plot(x,y2,type="l",col="green") But when I do it like this, they are not plotted in the same plot together. In Matlab can one do hold on, but does anyone know how to do this in R?

• JFace: difference between ITreeContentProvider and ILazyTreeContentProvider

  - by Alexey Romanov

  After reading JavaDoc for ILazyTreeContentProvider and Virtual Tables and Trees I am a bit confused. Do they really mean that with a simple ITreeContentProvider all elements have to be loaded when the tree is created? I expected that getChildren() would only be called when expanding an element (and hasChildren() to be called to determine whether the plus sign should be shown). Or are they intended for the case where some elements have many children?

• Is JavaScript allowed to call a remote web page during a click event?

  - by Blankman

  When viewing the click in firebug, the call turns red (i.e. error) but I can't see the error because the page redirects. So is it allowed to call a remote website (in my case, its a 1x1 image using a standard url like http://www.example.com/becon).

• Looking for a good semantic parser for the Russian language.

  - by Gregory Gelfond

  Does anyone known of a semantic parser for the Russian language? I've attempted to configure the link-parser available from link-grammar site but to no avail. I'm hoping for a system that can run on the Mac and generate either a prolog or lisp-like representation of the parse tree (but XML output is fine as well). Thank you kindly in advance, Gregory Gelfond

• What text editors support vertical rulers?

  - by leeand00

  I'm looking for a feature somewhat like the vertical red 80 columns marker in NetBeans but one that's easier to use. I'd like it to function more like the tabs in MS Word except that the horizontal line is displayed on the entire file. I looked on the Comparison of Text Editors over at Wikipedia and I didn't find that "vertical ruler" was one of their features. It would be used to line up html tags in a massive file that I did not create, but have to maintain.

• Python ttk.Button -command, runs without button being pressed

  I'm making a small script in python with ttk and I have a problem where a function runs where it shouldn't. The button code looks as follows: btReload = ttk.Button(treeBottomUI, text="Reload", width=17, command=loadModelTree(treeModel)) btReload.pack(side="left") and the function is as this: def loadModelTree(tree): print ("Loading models...") allModels = os.listdir(confModPath) for chunk in allModels: ... For some reason, the function runs without the button being pressed. Why?

• What was the name of that interactive jQuery wizard plugin?

  - by poru

  Hello, a few weeks or months ago a (I think jQuery plugin) wizard was released, which allows you to do interactive "tutorials". You were able to create interactive boxes which relates to html elements and you were able to change to color of these boxes to red. It's also possible that it was "just" a javascript script and not a jquery plugin.

• Is it possible to seletively color a label in Silverlight

  - by joemoe

  For instance, if I have a label: Blah blah bladity blah I want the first 10% of this label, such that the font color should be red, and the rest should be green. This perhaps means it would color the Bl and PART of the a. Basically pixel-wise font coloring instead of character-wise. Is this possible and how would is be accomplished?
