Ive been to a bunch of sites and a couple said there was no way to do a for loop and the while and do-while loops didnt seem very good. Is there an official pseudocode site i could go to? -Raffi Re: pseudocode(sp?) help Nish Nishant27-Dec-01 16:45 Nish Nishant 27-Dec-01 16:45  I didnt think pseudocode had any set standards or formats Nish Sonork ID 100.9786 voidmain www.busterboy.org If you don't find me on CP, I'll be at Bob's HungOut XML Program vinuk27-Dec-01 15:40 vinuk 27-Dec-01 15:40  Hello, How do I write a program in Standard C++ that simply extracts the data contained in an XML document and removes the elements(tags). What I mean is, not a full fledged parser, but a simple program that extracts data and that's it. We could use the fstream object to load in the document and then I guess we will need to compare the document for '<' and '>' and remove those words? Thanks, Vinu. Re: XML Program Tim Smith27-Dec-01 15:56 Tim Smith 27-Dec-01 15:56  Take a look at the EXPAT XML parser. Sure, it does a LOT more than you need, but why reinvent the wheel. I am notorious for hating other people's code and wanting to write my own. But I LOVE EXPAT. Tim Smith Descartes Systems Sciences, Inc. Re: XML Program 27-Dec-01 16:18 27-Dec-01 16:18  I need to write code to simply report and extract information from the XML document. Hmm, this makes me think of PERL. Anyway, like I was saying, I don't want a parser, just some code so I can extract only the data instead of the elements. Also I just want to use Standard C++ and not MFC. Re: XML Program Michael Dunn27-Dec-01 16:44 Michael Dunn 27-Dec-01 16:44  Perl could probably do that in one line. Something like: perl -e '$/=undef; $_=<>; s/<.*?>/ /g; print;' < file.xml > output.txt I think $/ is the right variable to undefine to make <> slurp in the whole file, newlines and all. --Mike-- My really out-of-date homepage Buffy's on.

Could someone translate that into Standard C++ so I can compile it in C++? Thanks, Vinu. Re: XML Program Nish Nishant27-Dec-01 21:02 Nish Nishant 27-Dec-01 21:02  I second Time Smith . Use Expat.

Tim Smith Descartes Systems Sciences, Inc. writing and retrieving data from a file hforbess27-Dec-01 11:53 hforbess 27-Dec-01 11:53  Hello, Trying to bridge the gap between what I was taught in school and MFC. In school we created Btree file structures. It occurred to me that there is probably already made classes that are more sophisticated than the ones I created in school. Could someone point me in the right direction? Do I need to learn STL, for example? Say, for example, I wanted to write an MFC address book. I can do that but how do I write the data to a file and then retrieve when the program is run again? I mean, I cant see busting out my project and throwing into MFC. Seems like MFC would have a way to do such a common task. Do I need to look at CObject and serialization? Thanks in advance. harry Re: btrees and other file structures Nemanja Trifunovic27-Dec-01 12:28 Nemanja Trifunovic 27-Dec-01 12:28  There is no Btree in STL or MFC (or any other library that I know of). However, I'm pretty sure that some B-tree implementations can be found on the Web I vote pro drink Re: writing and retrieving data from a file Not Active27-Dec-01 13:04 Not Active 27-Dec-01 13:04  CObject and serialization would be a place to start. Depending on your requirements and/or ambition you may want to look at a database of some kind, Access, MSDE, etc. Otherwise simply writing and reading from a flat file or XML document may be sufficient. Re: writing and retrieving data from a file markkuk27-Dec-01 19:53 markkuk 27-Dec-01 19:53  The point of using STL or MFC containers is that you don't need to know the low-level implementation of the data structure (B-tree, AVL tree, hash table or whatever). MFC CMap class is probably what you should use for your application. Keyboard hooks... Rickard Andersson2027-Dec-01 9:44 Rickard Andersson20 27-Dec-01 9:44  I want to make a combination with Alt + F12... How to make it with hooks? ------------------------------ ©0d3 ©®4©k3® - That's me! ------------------------------ Re: Keyboard hooks... 567890123430-Dec-01 1:39 5678901234 30-Dec-01 1:39  What means "Make a combination"? If you want to handle Alt+F12 in the program, use WM_SYSKEYDOWN message handler. If you want to generate keyboard event, use keybd_event (Alt down, F12 down, F12 up, Alt up). If you want to handle Alt+F12 in keyboard hook procedure, all required information is in wParam and lParam. Win XP 27-Dec-01 7:52 27-Dec-01 7:52  I am trying to learn C++ and have the XP home edition on my computer. Does this mean I will not be able to create programs that have #include <iostream> in the include section of the code? Re: Win XP Rickard Andersson2027-Dec-01 9:03 Rickard Andersson20 27-Dec-01 9:03  What have you read when you think something like that is impossible! Well, #include is something that you write to include a file like windows.h to use functions and constants from that file... it works to use #include on any computer you want! You are a very very very very very... beginner on C++, aren't you!? ------------------------------ ©0d3 ©®4©k3® - That's me! ------------------------------ Re: Win XP 27-Dec-01 9:10 27-Dec-01 9:10  Well, the reason I asked is because I know XP hasn't got DOS and the book I just got has examples of code in it that have the include <iostream> in the begining. This is something I thought meant that the program is going to be a DOS type program. If it IS a DOS type program then I wont be able to see if it works on my machine. Right? I am really new to programming in hopes of someday being able to answer questions for people. If I CAN run these examples I'll have an easier time learning I think, right? Re: Win XP Ravi Bhavnani27-Dec-01 9:23 Ravi Bhavnani 27-Dec-01 9:23  Garry, The #include command simply includes a file into the current file and has nothing to do with the operating system. Also, you should be able to run DOS-like programs in a command window in XP. You should check your compiler's instructions for building and running console applications. /ravi "There is always one more bug..." ravib@ravib.com http://www.ravib.com Thanks 27-Dec-01 9:35 27-Dec-01 9:35  Thanks a lot, I appreciate your help!! Re: Thanks Christian Graus27-Dec-01 14:53 Christian Graus 27-Dec-01 14:53  Also, XP has DOS, it's just hiding the ability to boot to a comand line from you. You can still get to a command prompt from programs/accesories. This is the sort of window your console programs will bring up ( and I recommend writing some straight C++ to the console before playing with any windows stuff, which you appear to be doing ).
