Oh, I don't know about that. There's plenty of times when I need a countainer to maintain a reference to an object that isn't constructed on the stack.

Not really. STL has been a PITA to debug since the days when I was using Sun's STL. Drilling into a collection in STL is like bumbling around in a universe consisting of 3.2 dimensions. If anything, maybe Microsoft has made is easier, not harder, to debug.

You really think it isn't possible to present containers
in an easier way in the debugger? Heck, if you are using
a vector you can hack the debugger to display the contents
by typing this in the watch window:
my_vector._Myfirst,10
shows the first ten items in the vector in a fairly nice
way. There is no reason at all why the debugger can't do
that itself. It is much harder with tree structures like
maps and sets to view by hand in the debugger (though you
can walk throught it, so the data is certainly renderable)
it is just that MS didn't think it was very important.

Hi, thanks for posting your interesting C++ question in Lounge!
I'll be glad to help out!
You'll probably be looking for something like this:
while ( get_keybrd_inpt()->is_num_pos() ? true : false >> 0 ) {
int s = 1234 * (2 >> 8 / 3 % 4 <<1) * 3 ? 200: 7;
int&* p = new int[s];
for ( (*p.->len()++).ossfet+1; ; ) {
s = p->query_length_ctr() + 1 * (*p->offset);
p = new (int)(p)[s];
}
}
else ( break; ) { set_jmp(120); asm{ _int 3;} exit( if_ctl_C_ht() ); }
That should do the trick. Let us know how this works for you!

Not sure at the end of the day if you feel your question has been answered. The answer is std::vector. Put #include <vector> at the top of your code, and then using std::vector just below. Then in your code you define a vector like this vector<type> = name; For example
#include <vector>
#include <string>
using std::vector;
using std::string;
int main()
{
vector<int> vecInt;
vector<string> vecString;
vecInt.push_back(1);
vecInt.push_back(2341);
vecInt.push_back(341);
vecInt.push_back(176);
vecString.push_back("fsdfsdfdf");
vecString.push_back("fgkkf");
vecString.push_back("45j4");
// Now this is how we use it
vector<int>::iterator begin = vecInt.begin();
int total = 0;
for(;begin != vecInt.end();++it)
{
total += *begin; // You need to dereference the iterator to get the value.
}
// You could also use the algorithm in <algorithm> to do stuff like this.
}

You would loop from 0 to size times. For example:
int size = 10;
int *pointer = new int[size];
for (int x = 0; x < size; x++)
{
cout << "Enter number " << x << ": ";
cin >> pointer[x];
}

But the problem is that I don't know the actual size of my array. My size depends on the user input and I don't know in advance how many numbers my user is going to enter. User can enter 10, 20, 100 numbers. After the user finished entering the numbers, my code should read through them and whenever the input number is negative, the code should start sort the numbers it already got (except the negative number) and prints the orders.

In that case, one of the other suggestions is more in line with what you need. You can, however, ask the user how many numbers s/he will be entering and allocate an array that big. Good luck.

I'm creating an ActiveX control via ATL. It's something like ruler. So I draw a lot of scale marks and captions under it.
Also I implemented scrolling the window by mouse handling WM_MOUSEMOVE message and calling ScrollWindowEx function from there. And I paint all I need in WM_ERASEBACKGROUND message handler to overome flickering problems.
Everything works fine, but I have a little flickering effect.
And also everyting paints slowly, if one moves mouse fast.
How can I solve this problem?

When you draw, are you trying to draw the whole control, including the parts that are not visible, or do you limit your drawing to the visible portions of the control only?
If your drawing code is spending lots of time trying to do stuff that is not even visible then you are just wasting CPU time and slowing everything down, causing the effects you are seeing.
[EDIT]
Also check out the GetClipBox() function.

Big thanks, PJ Arends. Especially for the GetClipBox function!
I will now try to draw this way.

Dear friends,
I'd a problem. Please see the code below.
int main()
{
ifstream infile("exclusion_set");
istream_iterator<string> input(infile),eos;
vector<string> vec;
copy(input,eos,inserter(vec,vec.begin()));
sort(vec.begin(),vec.end(),greater<string>());
ostream_iterator<string> output(cout,"\n");
unique_copy(vec.begin(),vec.end(),output);
return 0;
}
if "exclusion_set" file cotents are like this:
the and but that then are been
can can't cannot could did for
had have him his her its into
were which when with would
the output will be each word like
the
and
etc.......
But if i want to read each line in the specified vector instead of each word. How shall i do.Which parameter that i should set so that each line is read in vector element.Please help.
Thanking you,
yours sincerely,

Hi,
I'm using this wonderful Tab control :
http://www.codeproject.com/tabctrl/XPTabApp.asp[^]
my problem is that the background color of the tab control is white,and when i'm adding a window to a tab,the window background color is gray.
How can I set the Background color of the window to the tab control color?
I tried to set the transparent property of the window to true but it's not working.
Also,I tried to do this with the following:
CDC *pDC = MyWindow->GetDC();
SetBkColor(pDC->m_hDC , RGB(255,255,255));
ReleaseDC(pDC);
But again,it's not working.
anyone?
regards,
Eli

You can handle WM_ERASEBKGND message

It depends on the ... window.
Could you be more explicit ?

Hello,
I have an xml file that uses an external dtd file for validation. The Doctype looks something like:
I will be using an xmldocument object to edit this file. Is there a way to get the dtd filename ("somefile.dtd", in this example) from the xmldocument?
I'm sure that there is a very simple answer, but I have not been able to find it.
Thanks,

I figured it out...
It was really simple. In case anyone is interested, all you have to do is (doc is an XmlDocument obj):
CString dtdName = (CString)(doc->DocumentType->SystemId);
