Hi, I am beginner to ASP.Net. I just learned Application[] class and session[] class. My question is which one is better? And where i have to use application[] object and where i have to use session[]. I have one more doubt: I have two asp pages, Page 1: take the choice from the user where i have three check boxes. check 1. person names start with 's' check 2. person names starts with 'a' check 3. person name starts with 'g'. So page one is contains above three check boxes. When user selects check box and submitted, it goes to second page where i have to write code for get the values from data base based on check boxes user selected. For this kind of problem can i use Application[]. Or any other method to write solution for this..... Thanks in advance .....

I have one doubt please give me the answer. I read some where in C++, if we want to access base class constructor using derived class constructor like bellow is possible:

class base
{
base()
};

class derived:public base

{
derived():base()
{
}
};

normally i used like bellow

class base
{
base()
{
}
};

class derived:public base

{
derived()
{
}
};

My question is what is the difference between both approaches. In which cases I have to use first one and in which cases i have to use second one.

Hi to all Please look at the following code:

class base
{
public:
void show_base()
{
cout<<"executing base"<

  In the above my problem is "I want to access a base class member function.i.e when i called show\_derived(), it needs first calls show\_base() and then show\_derived() remaining code should execute. Is it possible to call like this. Or please show me any other possibilities 

Thanks in advance......................

Hi to all, I am using windows registry. please look the following.

const char* subkey ="Software\\Microsoft\\Windows NT\\CurrentVersion";

  if(RegOpenKey(HKEY\_LOCAL\_MACHINE,subkey,&hKey)== ERROR\_SUCCESS)
  {
	  cout<<"register is opened";
  }
  else
  {
	  cout<<"still not working";
  }

Above one is working correctly. And also displaying the message correctly. But when subkey i written like follows it is not working.

const char* subkey ="Software\\Microsoft\\Windows NT\\CurrentVersion\\Windows Messaging Subsystem";

I am not getting the exact problem please address the solution.... Thanks in advance.....

My interviewer thrown a question like: He wants to implement a function where he needs to takes two char* parameters as input at the end it should return a char* by concatenating these two char* values(without using strcat(), strcmp() functions). required function prototype is

char\* concat(const char\* c1, const char\* c2)

I am unable to solve this one. Please give me the approach Thanx in advance.....

You could use strcat()[^] to concatenate strings.

Actually my requirement is "not use the strcat() function".

Hi to all, I have a small doubt.Is it possible to use arithmetic operators between two char* variables, like bellow

char\* conc(const char\* c1,const char\* c2)
{
 char\* c3=c1+c2     // error" adding two pointer variables is invalid   
 return c3
}

Above code is giving error "adding two pointer variables is invalid". Please tell me how to concat(add) two char*.

Hi, Try like this may be its not correct approach. But it solves your problem.

public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}

    private void Form1\_Load(object sender, EventArgs e)
    {
        string s1 = this.richTextBox1.Text;
        sample o1 = new sample();
        o1.sobject = s1;   
    }

}
public class sample
{
    public string sobject;
   
}
