Hello everybody I am very sorry to post this type of questions on this forum but
believe me its only your help that will clarify all my doubts.

After reading some articles on the forum
I concluded life-cycle of a typical MFC program as below in sequence.


1. WinMainCRTStartup
2. WinMain
3. AfxWinMain
4. AfxWinInit
5. InitApplication
6. InitInstance

Global RUN function is embeded in theApp (Global Object of my Application) which
handels all the default windows messages.


If I am wrong please correct me or give me a link where I can find more info about this.

void MySliderTest::OnCustomDrawMySlider(NMHDR* pNMHDR, LRESULT* pResult) <br />
{<br />
	if(i<m_sliding.GetPos())<br />
	{<br />

Whether C++ templates and generic programmings concepts are same?.

An example:

//function that calculates the sum of two ints without using templates... 
 
int Sum(int nNum1, int nNum2)
{
    return (nNum1 + nNum2);
}
//The above function can calculate the sum of only two ints
 
//for eg:
 
int nSum   = Sum(2, 4);
 
//What about two floats...
 
float fSum = (float)Sum((int)2.0f, (int)3.5f); //eek :eek:
 
 
 
//function that calculates the sum of any two number of the same type using templates...
 
template<class T> T Sum(T num1, T num2)
{
    return (num1 + num2);
}
 
//how to call this function
 
float    fSum = Sum<float>  (2.0f, 56.34f);
int      nSum = Sum<int>    (2, 56);
double   dSum = Sum<double> (2.002, 56.809);
 
//see this is what generic programming is all about
