Hello, I’m almost done with learning the basics of c++ and can do some programming with it, but I am as you also intrested in web development, so couple of days ago I found this book on net, Learning PHP, MySQL, JavaScript, and CSS, 2nd Edition
Link:

http://shop.oreilly.com/product/0636920023487.do

I’m planing to go through this book, so that I can get the insight on web development, and then later in case I need some more knoweldge then I will find some books separately only for PHP, Javascript, and others.

So all file locations which require server-side manipulation can be written in the script using functions like dirname(__FILE__)./includes/config.php but any links in the html should avoid these kind of absolute paths embedded into them via PHP tags and should just refer to the file link relatively e.g. /includes/config.php.

you really have made this as difficult to answer as you possibly could. When asking questions like this, you need to provide your code. Anyway, see if this explains some of your problems:

#include 
#include 

typedef struct {
   int DayNumber;
   int WorkHours;
} WorkDay;

typedef struct {
   char name[30];
   long ID;
   int workdays;
   WorkDay * wd;
   double salary;
} Worker;

Worker *newWorker() {
   Worker *w = malloc(sizeof(Worker));
   w->wd = malloc(sizeof(WorkDay));
   return w;
}

int main()
{
   Worker *temp = newWorker();
   printf("What day?");
   scanf("%d",&(temp->wd->DayNumber));
   printf("Day supplied = %d\n", temp->wd->DayNumber);
   free(temp->wd);
   free(temp);
   return 0;
}

while (t/2 && heap[t]>heap[t/2])
this line is equals to:
while( t/2 != 0 && heap[t]>heap[t/2])

while loop is false if argument is 0.

while(1) is true
while(!0) is true
while(27) is true
while(0) is false

The code looks reasonable, assuming that the motor commands are correct. This would indicate that something else is wrong. Possible problems are:

    myLight points to the wrong sensor
    SensorValue[myLight] returns a value other than what you expect
    colour[2] contains the wrong value

One other possibility is that the preceding code has an error that causes this code to be skipped.

Use the ADO.NET EntityFramework to make your life a lot easier.

Anyway, if you’re going to make something that involves multiple users and multiple queries being executed on the database at any given time, don’t use Access or you’ll run into concurrency issues sooner or later. Obviously MSSQL works best with .NET, as they’re both Microsoft technologies and they tend to give that little bit of extra compatibility with their own products. However, MySQL or any other ODBC database should work just fine.

[Adelaid]

Here is my code in the format you’re looking for

import java.util.Scanner;

public class lab13zad3{
    public static void main(String[] args) {
       Scanner sc= new Scanner(System.in);
       
       String word;
       String words[]=new String[100];
       int i=0;
       
       String k="end";
       System.out.println("Write some words: ");
       word=sc.next();
       
       //Add words to the array
       while(word.compareToIgnoreCase(k)!=0)
       {
         words[i] = word;
         i=i+1;
         word=sc.next();
       }
       
       //Add "end" after receiving all the words
      words[i] = k;
      System.out.println("The received words are:");
      for(int j=0;j 0)
           System.out.println(words[j]);
      }
     
      System.out.println("Word with a space between each character");
      for(String w:words)
      {
        if(w != null && w.length() > 0)
        {
          char temp[] = w.toCharArray();
          for(int c=0;c

Judging by what you said and the code you can literally just do

if ($myusername == "Joe") { do something }

If you wanted to do it based on usergroup or something then you’d need to execute a separate query, check then redirect accordingly.

[Adelaid]

Make a P1.cpp file as shown in SoundTestForm; also make a main.cpp file.Write the codes shown. Call the .cpp file as P1.cpp(see it is included in the main.cpp codes)
Make wav file of any music file and store it in a drive.Put the correct path in the
form that shows on running this code. Press play.Bingo,there goes your sound track.
The only disadvantage here is wav file is ten times larger that mp3 file.

This is ok for experimentation.For practicality you should find a way to convert mp3 to wav
in this program itself,so that conversion is done as it plays.
regards and blessings

Are you looking to write a windows app from scratch or are you looking for an app to convert your web code into an exe?

If you want a convertor then what language?

eg. There are quite a few PHP to EXE…

http://wiki.swiftlytilting.com/Phc-win
http://sourceforge.net/projects/wapache/
http://www.bambalam.se/bamcompile/
http://www.zzee.com/phpexe/

you need to set it up to email the info to you

does your web host support “CGI”

The information isn’t strictly correct, but the idea is basically right. The simple answer to your question is that the increase in size of the company implies an increase in size of the data requirements. The usual split is:

One- or two-person companies use Excel
The solution is simple and cheap and very low-maintenance. One person with knowledge of Excel can handle everything.
Very small companies use Access
This allows some data to be shared, although it’s not a very scalable solution. Again, it’s simple and it’s usually maintained by someone in the office who has a good grasp of MS Office.
Small-medium companies use Microsoft SQL server
Large companies use Oracle or DB2
This is a “real” database, but it lacks the enormous power of Oracle or DB2. The reality is that there is little to choose between these three in terms of functionality, but the MS solution only runs on Windows and doesn’t scale to the sizes needed by large companies.
Companies with extraordinary requirements for data use NoSQL solutions like Hadoop
This is Google and Facebook, etc.

SAP is not a database, but an enterprise software solution. It usually runs on Oracle or DB2 as its database. I have no idea why this was added to the list – it just doesn’t make sense.

Interestingly, DB2 is often forgotten by people when talking about databases, but it’s the second-biggest seller after Oracle – see Computer Weekly:

http://www.computerweekly.com/feature/Choosing-the-right-database-management-system

Visio can create ER diagrams from ‘reverse engineering’ tables in an Oracle database. I think TOAD can do it too.

Actually there are 2 routes to take:

1. c -> c++ -> c# .NET
2. java SE -> java EE

Both have it’s advantages and disadvantages, but if you are new to the programming world java should be your choice not c++

Remember all matrix use a double for, so use it for the input and output

   for (int i = 0; i < n; i++) {
      for (int j = 0; i < n; j++) {
         //the multiplication process here
      }
   }
