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.

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 ?

I tried using the Picture Box control, but it resized my icon down to 16x16, and I want to show a 64x64. Any help would be much appreciated.

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);

Ok. I know this is really basic, but why can't I find the constructor code to open my documents from a button control? (MFC) I must be using wrong search key words, because I can't find it here. Can any one point me in the right direction?
Thanks,

Try to use CDocTemlate class for this purposes, OpenDocumentFile member.
You must register DocTemplate first!
Another way is to use CWinApp::OpenDocumentFile or AfxGetApp()->OpenDocumentFile instead.

For your CDocument-derived class?

Using the class CLimitSingleInstance I have managed to enusure that only one instance of my application is active.
I would like to do one more enhancement.
Whenever there is an attempt to run multiple instance the current running instance should be restored to full view.
I think it has to be done in the InitInstance() of my appln.
Can anyone suggest the procedure.

Hi
if your instance is already running you should call showwindow() with maximise option.
Hope it works
