you are sooo lazy!

If you don't want to learn how to program then take a different course, if you do want to learn then try to learn it by having a go yourself first.

How can you cheat and have integrity? They are mutually exclusive things.

Eh, mostly being sarcastic, but if the OP wants someone to do his (her?) work for him/her, the least he or she can do is pay someone...

Hi All,
If I'm instantiating a template class with 5 different objects, how many function signatures will be there in the memory?
My assumption is that, there will be 5 different signature since the object type are different. it so sad that, we can't debug a template class Frown | :(

for e.g. see the pseudo code below

template<class T> class MyTemplate
{
public:
	void Fxn(T inputval)
	{
		printf("Function called %d",inputval);
	}
};

int main()
{
	MyTemplate<int> objint;
	objint.Fxn(10);
	MyTemplate<float> objfloat;
	objfloat.Fxn(15.0f);
	MyTemplate<short> objshort;
	objshort.Fxn(20);
	MyTemplate<double> objdouble;
	objdouble.Fxn(25.5);
	MyTemplate<long> objlong;
	objlong.Fxn(30);
}

is ur code exceuting i feel it should be
class MyTemplate
{
public:
template <class T> void Fxn(T inputval)
{
printf("Function called %d",inputval);
}
};

I meant it is not easy to get the function address that's what I said. Nice Joke Smile | :)

Anyway I have added one more statement in my "Fxn" function which prints the address.

printf("Function Address%x\n",Fxn);

I'm not sure whether it is correct or not but the output is like this

<br />
Function Address401000<br />
Function called 10<br />
Function Address401030<br />
Function called 0<br />
Function Address401060<br />
Function called 20<br />
Function Address401090<br />
Function called 0<br />
Function Address4010c0<br />
Function called 30Press

I have added one more object of type int, like this

MyTemplate<int> objint;
	objint.Fxn(10);
	MyTemplate<int> objint1;
	objint1.Fxn(100);

it prints same value as the function address

So as per the above code & results it seems that, there are different function signatures

Take a look at the atoi[^] and itoa[^] functions.

First, retrieve the text in the edit controls (with GetWindowText), transform it into an int with atoi, add them together and convert the result into a string with itoa. Then display it in the other edit control with SetWindowText.

You can overwrite the WM_CHAR message to accomplish this. It should do the trick you need. Good luck!

To override WM_CHAR he should have a separate class derived from CEdit.

Not to. Personally, I hate it when a program decides to add stuff to what I'm typing. If I want a space after a full stop, I type one. Period. Smile | :)

However, if you must, handle WM_CHAR. For the case where the character is a full stop, add a space. (MFC use OnChar in a derived CEdit class)

But beware. If the user has selected text, and replaces it with a full stop, would you want to append a space in that case too, or only if there wasn't already one?
