Which version of Hibernate are you using?

3.2.5 Hibernate

and Spring 3.0.2

Hello guys, I am using Hibernate + Spring with netbeans to make a web application. I have it working correctly and displaying data from the DB. My problem is I only know how to do one hibernate query which is shown below.

How can I do insert/delete queries. For instance in my JSP page I have a button, how can I make it so when a user clicks on a button it deletes a specific record from the database. In essence how can I pass parameters to my controller. and can someone explain when/how I need to use DAO objects.

Thanks!

that's dumb.

what if he wants to add 9999 as one of his numbers

Cool thanks for coming in offering no valuable input of your own just destructive criticism. If choosing 9999 is a problem he could use a different sent value it's just a suggestion.

Moron.

I would do something different and use a sentinel value to terminate input. Loop until users stops the loop.

int value, count=0, sum=0, total;
    
    for(;;) // out forever loop
    {
        for(;;) // 
        {
            cout << "Enter value " << count+1 << ": ";
            value = -9999;
            cin >> value;
  
        
          
            cin.clear();
            cin.sync();

            if ( value == -9999 ) { cout << "Bad data entry ... "; continue; }
            if ( value ==  9999 ) break; // break out of inner loop
            
++count;

total= sum += value;
average= total/count;         
                       
                      
    
           
        } // end of inner forever loop ...
        
        if (value == 9999 ) break; // break out of outer loop
      
   
    
    } // end of outer forever loop ...

Hello i'm rather new to Python and I was wondering how I could do a menu to prompt the user to choose a number and execute a certain part of code based on his choice.

For example:

please choose an option
1)
2)
3)

then based on users input, it executes only that part of the code.

Would i just do something like

if choice ==1 :
do this

if choice ==2:
do this

ect?

got it thanks for the help

did that still not printing out even or odd

hi, im trying to learn python and this is giving me

>>> x=input("Enter a value: ")
if x % 2 ==0:
print ("even")
else:
print ("odd")

then when i execute:

Enter a number:

then i enter a number but it does not print even or odd. why?

Make sure you have the Ming compiler, and put the Dev c++ executable and the .cpp file into the same folder.

Then try execute --> rebuild all.

then if still nothing, uninstall and reinstall.

  return rate;  

}
}

Hello I tried to change some things like you said but it still did not work. I am pretty terrible at c++ so if you can explain once again what's wrong that would be super.

The program is supposed to loop 3 times, each time returning a rate based on the value i sent it from the function call at the top. But it's not doing that.. not at all. Each time it loops it's supposed to read the next value in the array.. Though that's not working either.

//6.12

#include <iostream>
#include <iomanip>

using namespace std;

double CalculateCharges (double car1=1.5,double car2=2.0,double car3=24.0);

int main ()

{




cout<<" Parking Garage Rates " << endl;

cout<<setw(10);
cout<<"Car"<<"Hours"<<"Charge"<<endl;

double car1;
for (int i=1;i<=3;i++)
cout<<i<<CalculateCharges(car1)<<endl;

cout<<"Total"<<endl;

return 0;

}
//+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++


double CalculateCharges(double car1, double car2, double car3)
{
    double rate;
    double hours[3];
    hours[0]=car1;
    hours[1]=car2;
    hours[2]=car3;
    int b;
    for( b = 0; b <= 3; b++ ){
   hours[b] = b;
   }
    for (double h=0;h<=24;h=+hours[b])
    {
    if (h<=3)
    rate = 2.00;
    else if (h>=3)
    {
    rate = (.50*h);
    }
    else if ( h == 24 )
    {
    rate = 10.00 ;
    }
    
    

}
}

So the thing complies, but it does not generate any numbers, or anything like that.. I'm confused.. help.

You're absolutely right...

I should sacrifice two goats.

Hello, I have a program that's 95% written. I am getting weird results though, so I will need you to fix it and EXPLAIN why that worked.

This should take an experienced programmer less then 30 minutes. I would post it on here, but it's over a thousand lines of code. Simple stuff, arrays and classes, but just too tedious to read through.

If you're interested send me a PM please. TY for your time. I will pay through pay-pal. If this post is against forums rules, my bad and go delete it plz. :(

Ok i fixed that but now when i run main i get..

Hey thanks you've been a giant help. 2 more questions while you are here =P

What do i sent the PrintCard from main it is asking for an int value?

and my next function will be to assign value to the cards, the problem is how is it going to refer back to the shuffle and printcard constructors?

quick problem i get like this:

no match for 'std::operator<< [with _Traits = std::char_traits<char>](((std::basic_ostream<char, std::char_traits<char> >&)(&std::cout)), ((const char*)"human has ")) << ((Blackjack*)this)->Blackjack::PrintCard(((Blackjack*)this)->Blackjack::deck[0])'

note C:\Dev-Cpp\include\c++\3.4.2\bits\ostream.tcc:63 candidates are: std::basic_ostream<_CharT, _Traits>& std::basic_ostream<_CharT, _Traits>::operator<<(std::basic_ostream<_CharT, _Traits>&(*)(std::basic_ostream<_CharT, _Traits>&)) [with _CharT = char, _Traits = std::char_traits<char>]

and i have absolute 0 idea what that means

Ok so now the problem becomes that i need to send to printcard whatever value the shuffler comes up with each time it shuffles the deck, how do i do this?

Hey stu appreciate the input, but you're code is a little bit over my head. I'm just getting into pointers so i will use it as a reference :)

BTW on my current blackjack program im having trouble resetting the hand after each game, as in the game is over computer won with blackjack, how do i clear hands and reshuffle the deck and redeal.?

yea... i'm so stupid.. Thanks for that one vmanes.

BTW could you suggest how i should deal out the cards, i need 2 cards for human 2 for computer to start. So should i do a function call to my shuffler to generate 4 random cards or?

I'm trying to make a shuffler for a blackjack program it's supposed to give me back a random number from a deck of cards each time i call it. But it's also supposed to keep track of cards out of the deck..

I need to make it a function call, but before i do that it's not even working in the first place... it's giving me 51 random crazy numbers..

help please?
