There's no point googling if you don't actually read the resulting pages

I've never seen such code before and don't know if it even compiles.
But it uses the conditional operator ( ?: ) in the return statement and continues to call the main method until i has been decremented below 0, and since the main method prints the value of i and the decrements it, the effect is to print 321.
Very bizarre code.

Homework?
There's two things you need to understand here, what static does to that variable declaration, and what the test ? then : else; operation means...

Yes. Remember i is static.

first of all, when posting code, please use the <pre></pre> tags to keep a well formated message.
then, to understand your result, keep in mind that static variables (declared within a function) stay local to the function (so, not visible from outside) but their lifetime changed to being the program lifetime. that is, a local static variable is initialized at the beginning of the application, and is destroyed when the program exits.
at the first call of the function, the variable as the initialization value. then, each time the function is called, it keeps the last value it had when the function last exited.
int main() {
static int i=3;
printf("%d", i--);
return i>0 ? main():0;
}
1. entering main for the first time:
i == 3
so, 3 is printed (because the i-- decremented the variable only after returning the current value)
i now equals 2
the i>0? main : 0 expression is evaluated. as i is strictly higher than 0, main() calls itself recursively
2. entering main for the second time:
i == 2
printing 2
i == 1 (after decrementation)
i > 0, so re-entering main()
3. entering main for the third time:
i == 1
printing 1
i == 0 (after decrementation)
i not > 0, so returning 0
for all the previous calls to main, the expression returns 0 either, until exiting...

I am coding for VC++6.0 application, now I want to upgrade my VC++ application to VC++.NET, so that it can run on Windows Vista, is there any tool present using which i can upgrade my application?

What do you mean by upgrade ? You can use VS2005 VS2003 IDE to open your project, and correct any warnings/errors, if occurs. Thats the way to go about it.
deepasaral wrote: so that it can run on Windows Vista,
Well, unless, there is some registry related code, there should not be any problem running it.

prasad, VC++.NET is not VS2005 but VS2003 
they removed the .NET part in the name since people were confusing about it's ability to produce native code

The method that getting the event return me LPNMHDR pnmh type -- with this type i do casting to
NMTREEVIEW* that will hold me
TVITEM itemOld;
TVITEM itemNew;
None of them are not hold me the info of the right HTREEITEM .
I must have the right HTREEITEM to know which item was selected in case of click event or/and double click event.
I will be happy to get any help to find out the problem.

Did u set the image list to the list view using the LVM_SETIMAGELIST function?
amitmistry_petlad wrote: ImageList_AddIcon(hSmall, hIcon);
did u check the above function return success?
amitmistry_petlad wrote: 1)I want to display my first column's image on right side(right alingement)
If you want to do so, you have to do custom draw( by handling NM_CUSTOMDRAW notification)
2- i didnt understand
3. if a cell have only image, and if you call Getitem, the pszText member of the LVITEM will be having 0 length.
