Hi everybody,
how to overwrite part of an existing file without loosing the remaining information???
ex: file contains info about employees loke empId, salary,Company etc. Now if i want to change company name of a specific employee Id how to achieve it??

What is the format of the file ?
Me think you will need to load the file in memory, modify the structure internally and write back to the file.

HI
I want to get two keys from the keyboard simultaneously , I mean when you press and hold two keys the kbhit() and getch() functions return only the first pressed key .
thanks

This is impossible since the link from the keyboard is serial.
The only way to detect if two keys are pressed simultaniously is if one of them is a shift-key or similar since that would have an impact on the scan code.

That is incorrect. The GetAsyncKeyState() function will return the status of any key on the keyboard, up or down.
You can use this macro:
#define KEYDOWN(vk_code) ((GetAsyncKeyState(vk_code) & 0x8000) ? 1 : 0)
to determine if a key is currently being pressed. This will check key state even if your application does not have focus. If you are actually wanting to capture the key presses, you would actually have loop through all of the key codes and check individual status with this method.

Whether the link to the keyboard is serial or not isn't a matter of opinion.
I guess I misinterpreted the OP's problem and what he meant with "simultaneously".
If the question is "how can I determine what keys are being held down", then the answer is "poll the keys with ::GetAsyncKeyState()", like you suggested.

Hello,
I use a template class where I would like to overload the operator [ ].
My intention is that not only the instances of the class will call the operator but also the types of the instances.
I have tried the following code. It works but never the operator [] is called.
Please could tell me if is there a solution to use my own overloaded operator with any type like int, float, long etc..
Thanks for your kind answers.
//ClassTest.h
template <class type>
class ClassTest
{
public:
ClassTest(){};
virtual ~ClassTest(){};
type* Date;
inline type& operator[](UINT i_index){return (at(i_index));};
};
main()
{
// test 1
ClassTest <int> theInt;
theInt.Date = new int[10];
theInt.Date[0] =5; //Does not call type& operator[]
//test2
int array[] = {1996,1997,1998}
ClassTest <int> figure;
figure.Date = array;
int xx = figure.Date[1]; //Does not call type& operator[]
}

You haven't called the [] operator for the template class in either of your examples.
Instead of
theInt.Date[0] =5; // This is using default [] operator to index into the "Date" member.
it should be
theInt[0] = 5;
This will call your operator but it won't compile since you have no "at()" method defined.
