• Is there any way to determine what type of memory the segments returned by VirtualQuery() are?

  - by bdbaddog

  Greetings, I'm able to walk a processes memory map using logic like this: MEMORY_BASIC_INFORMATION mbi; void *lpAddress=(void*)0; while (VirtualQuery(lpAddress,&mbi,sizeof(mbi))) { fprintf(fptr,"Mem base:%-10x start:%-10x Size:%-10x Type:%-10x State:%-10x\n", mbi.AllocationBase, mbi.BaseAddress, mbi.RegionSize, mbi.Type,mbi.State); lpAddress=(void *)((unsigned int)mbi.BaseAddress + (unsigned int)mbi.RegionSize); } I'd like to know if a given segment is used for static allocation, stack, and/or heap and/or other? Is there any way to determine that?

• null pointer exception on list.add

  - by Eric

  I've been working on this one error for a few hours so I thought I'd pick the brains of some pros. I am getting a null pointer exception at the modelData.add(i, es) method. I know from debugging that es isn't null. I'm really confused, thanks. public class EventTableModel extends AbstractTableModel { //private int rowCount = 0; protected List<EventSeat> modelData; private static final int COLUMN_COUNT = 3; private Event e; Event j = GUIpos.m; int i = 1; public EventTableModel(Event e) { this.e = e; try { System.out.println(modelData); for (EventSeat es : e.getEventSeats()) { modelData.add(i, es); i++; } } catch (DataException ex) { Logger.getLogger(EventTableModel.class.getName()).log(Level.SEVERE, null, ex); } }

• How to parse JSON string that can be one of two different strongly typed objects?

  - by user852194

  Background: I'm invoking a web service method which returns a JSON string. This string can be of type ASConInfo or ASErrorResponse. Question: Using the DataContractJsonSerializer, how can I convert the returned JSON string to one of those objects? Thanks in advance I have tried the following technique, but it does not work: public static object test(string inputString) { object obj = null; using (MemoryStream ms = new MemoryStream(Encoding.Unicode.GetBytes(inputString))) { DataContractJsonSerializer ser = new DataContractJsonSerializer(typeof(object)); obj = ser.ReadObject(ms) as object; } return obj; } [WebMethod] public string TypeChecker() { string str = "{\"Error\":191,\"ID\":\"112345678921212\",\"Length\":15}"; //string strErro = ""; object a = test(str); if (a is ASResponse) { return "ASResponse"; } if (a is ASErrorResponse) { return "ASErrorResponse"; } return "Nothing"; }

• Linq to SQL and Realtime Data

  - by Jeremy

  I have an application that needs to constantly (every 50ms), call to an MVC action, and pickup/drop off data. I am using Linq to SQL and MVC because of how simple they are to implement, and I know that they aren't perfect when it comes to performance, but it works relatively well, but the best speed I can get with my current approach is 200ms (without requests overlapping). Each call to the site will create a new instance of the datacontext, query/insert it and return that data. Is there a way to have the datacontext static, but submitchanges say every 5 seconds, so that i am pretty much hitting an in-memory version of the data?

• Purpose of IF, ELSE, FOR macros ?

  - by psihodelia

  I have a source code of a library which has a lot of strange IF, ELSE, FOR, etc. macros for all common C-keywords instead of using just usual if,else,for,while keywords. These macros are defined like this: #define IF( a) if( increment_if(), a) where increment_if() function is defined so: static __inline void increment_if( void) { // If the "IF" operator comes just after an "ELSE", its counter // must not be incremented. ... //implementation } I don't really understand, what is the purpose of such macros? This library is for a real-time application and I suppose that using such macros must slow-down an application.

• Serialize an object to string

  - by Vaccano

  I have the following method to save an Object to a file: // Save an object out to the disk public static void SerializeObject<T>(this T toSerialize, String filename) { XmlSerializer xmlSerializer = new XmlSerializer(toSerialize.GetType()); TextWriter textWriter = new StreamWriter(filename); xmlSerializer.Serialize(textWriter, toSerialize); textWriter.Close(); } I confess I did not write it (I only converted it to a extension method that took a type parameter). Now I need it to give the xml back to me as a string (rather than save it to a file). I am looking into it, but I have not figured it out yet. I thought this might be really easy for someone familiar with these objects. If not I will figure it out eventually.

• Is there any way to pass an anonymous array as an argument in C++?

  - by Jeremy Friesner

  Hi all, I'd like to be able to declare an array as a function argument in C++, as shown in the example code below (which doesn't compile). Is there any way to do this (other than declaring the array separately beforehand)? #include <stdio.h> static void PrintArray(int arrayLen, const int * array) { for (int i=0; i<arrayLen; i++) printf("%i -> %i\n", i, array[i]); } int main(int, char **) { PrintArray(5, {5,6,7,8,9} ); // doesn't compile return 0; }

• Div behind another div problem.

  - by Kyle Sevenoaks

  Here is a (big) example of the massive problem I am having, when this page is live at euroworker.no/order, it is dynamically generated, I have supplied a static version for people to mess with. All I need is where it says "Endre Valg" to push the div wrapper under it down.. Sounds easy huh? I have tried many many things, I hope that some discussion and even trial and error can help us here. Sorry for the huge amount of code and stuff but this has taken me all day and I am out of ideas. Thanks.

• xcode storyboard reverting in compile

  - by darren

  I started having some very odd behaviour in Xcode 4.5 recently. I made a change to a UITableViewController with static cells but the changes did not appear in the simulator and neither did my code changes. I removed the app from the simulator and ran clean on the project, then started again and all the changes appeared. I made another code change, ran the debugger via simulator and once again I saw my old UITableViewController values and my code changes were absent. This project is using storyboards, but I am not sure if this problem is related to just storyboards given my code changes are reverted as well. I am deeply confused here. Not even clean fixed this issue. Any thoughts or suggestions?

• Render an asynchronous report, wider than the screen, without extra scrollbars

  - by Dubs

  I have an asynchronous local SSRS 2005 report that is of variable height and width, but routinely is bigger than the screen. I want to render it full size so that some of the report renders off screen and the only scrollbars the user sees are the ones on the browser window. What is the best way to accomplish this? The only method that I've found that even comes remotely close to what I want is to set static width/height values that are much larger than the report will ever be. But, this is undesirable since it leaves so much extra whitespace in the browser window. Has anyone had success rendering asynchronous reports without the extra scrollbars?

• identify the input that is multiple of 11 and odd or even java

  - by Bolor Ch

  i am trying to write code to determine the nature of input using if statement only. The nature of input could be following: a multiple of 11 even or odd. For the code below, when I enter my input, it does not display the result as "input:NOT:ODD". Also how can I check multiple conditions with if statement? (else is not considered) import java.util.Scanner; public class test { public static void main( String args[] ) { Scanner input = new Scanner( System.in ); int x; int EO; int Mult; System.out.print ( "Enter value: " ); x = input.nextInt(); EO = x % 2; Mult = x % 11; if (EO > 0 && Mult > 0) { System.out.printf ("%d:NOT:ODD"); } } }

• Casting Class into String and Vice Versa in JAVA

  - by topgun_ivard

  I have a program in which I need to store a Class object into memory by casting it into String. Is it possible to convert the String back into the original Class so that I can use that class variables? I am doing this in JAVA. Example: test.java class hello{ public String h1; public String h2; } public class test { public static void main(String[] args) { hello h = new hello(); h.h1 = "hello"; h.h2 = "world"; String s = h.toString(); System.out.println("Print s : "+s); // Now I need to convert String s into type hello so that // I can do this: // (hello)s.h1; // (hello)s.h2; } } NOTE: this is not a homework, this is a personal project and I would be grateful if anyone can help! Thanks! Ivar

• Using Wordpress as a CMS to a site AND blog (two completely different layouts for each). Duplicate i

  - by Somebody still uses you MS-DOS

  I'm going to create a website using Wordpress static pages feature. It's going to have a menu for all the created pages. A blog is going to be created as well. This blog has a completely different layout/menu from the main site, but within the same domain: "http://www.domain.com" is the website url, and "http://www.domain.com/blog/" is the blog url. I was thinking of installing two different Wordpress instances: /var/www/public_html/ and /var/www/public_html/blog/. Although it's a simple solution, users are going to be duplicated: if you change password in one system, you need to change in the other. So, I would like to know from you which other approaches are possible: create a "dynamic" theme (call a theme when in root domain, another whern /blog - dont even know if this is possible), or for example a plugin to syncronize users from both instances? Does Wordpress MU solve this problem for me? Thanks!

• Can you have an extension method on a type instead of on an instance of a type?

  - by SLC

  I can have an extension method like this: DateTime d = new DateTime(); d = d.GetRandomDate(); GetRandomDate is my extension method. However the above doesn't make much sense. What would be better is: DateTime d = DateTime.GetRandomDate(); However, I don't know how to do this. An extension method created as: public static DateTime GetRandomDate(this System.DateTime dt) will only add the GetRandomDate() in the first example above, not the second one. Is there a way to achieve the desired behaviour?

• Get n Number of words using regex in Java

  - by Aymon Fournier

  I have a section of a book, complete with punctuation, line breaks etc. and I want to be able to extract the first n words from the text, and divide that into 5 parts. Regex mystifies me. This is what I am trying. I creates an array of index size 0, with all the input text: public static String getNumberWords2(String s, int nWords){ String[] m = s.split("([a-zA-Z_0-9]+\b.*?)", (nWords / 5)); return "Part One: \n" + m[1] + "\n\n" + "Part Two: \n" + m[2] + "\n\n" + "Part Three: \n" + m[3] + "\n\n" + "Part Four: \n" + m[4] + "\n\n" + "Part Five: \n" + m[5]; } Thanks!

• Replacing keywords in text with php & mysql

  - by intacto

  Hello, I have a news site containing an archive with more than 1 million news. I created a word definitions database with about 3000 entries, consisting of word-definition pairs. What I want to do is adding a definition next to every occurence of these words in the news. I cant make a static change as I can add a new keyword everyday, so i can make it realtime or cached. The question is, a str_replace or a preg_replace would be very slow for searching 3 thousand keywords in a text and replacing them. Are there any fast alternatives?

• Java Inheritance Concept Understanding

  - by Nirmal

  Hello All.... I am just refreshing the oops features of the java. So, I have a little confusion regarding inheritance concept. For that I have a following sample code : class Super{ int index = 5; public void printVal(){ System.out.println("Super"); } } class Sub extends Super{ int index = 2; public void printVal(){ System.out.println("Sub"); } } public class Runner { public static void main(String args[]){ Super sup = new Sub(); System.out.println(sup.index+","); sup.printVal(); } } Now above code is giving me output as : 5,Sub. Here, we are overriding printVal() method, so that is understandable that it is accessing child class method only. But I could not understand why it's accessing the value of x from Super class... Thanks in advance....

• Can the below function be improve?(C#3.0)

  - by Newbie

  I have the below function public static List<DateTime> GetOnlyFridays(DateTime endDate, int weeks, bool isIncludeBaseDate) { //Get only the fridays from the date range List<DateTime> dtlist = new List<DateTime>(); List<DateTime> tempDtlist = (from dtFridays in GetDates(endDate, weeks) where dtFridays.DayOfWeek == DayOfWeek.Friday select dtFridays).ToList(); if (isIncludeBaseDate) { dtlist = tempDtlist.Skip(1).ToList(); dtlist.Add(endDate); } else { dtlist = tempDtlist; } return dtlist; } What basically I am doing is getting the datelist using the GetDates function and then depending on the isIncludeBaseDate bool value(if true) skipping the last date and adding the Base Date It is working fine but can this program can be improve? I am using C#3.0 and Framework 3.5 Thanks
