I am assuming that Visual C++ is ISO C++ (with some Microsoft only features) and C++.NET is Managed C++ or "C++/CLI". I wouldn't say one is better than the other. Visual C++ can be used for low-level programming with high-level abstraction; thus, Visul C++ is powerful. IMHO, C++/CLI is (at this time) more of a bridge language between native code and managed code.

Nevertheless, you can learn Visual C++ from any book that covers ISO C++:

C++ Programming Language, Bjarne Stroustrup, ISBN: 0-201-88954-4
Ivor Horton's Beginning Visual C++ 2005, Ivor Horton, ISBN: 0-7645-7197-4

I think you are a clever boy!
My English is really poor,although I have studied English 13 years ,but I found it have no effect to me.
Sorry to say,I haven't pass the CET6 exam,by the way ,I'm a Master of computer,I still should to study English,it's boring.when I want to find some technique articles,it's hard for me to read English articles.
From this sentence I have wrote,you can sure my English is so poor,isn't it?
But you should know,I'm not a person who come from Europe or other country which said English.I think you had know where I from,lukily to say ,I come from a great and beautiful country.

What is better, a fork or a spoon ? I guess it depends on the task at hand.

How do you mean ? C++.NET is standard C++, with .NET extensions. If you know C++.NET, you know at least some C++.

Then for what tasks C++.NET is better and for which tasks VC++ is better.
Dont you think VC++ is lot more complicated than C++.NET ?
And if not then give me a simple windows based application example, explaining how you would achieve in both.
Obviously i know C++ but on .NET platform. So i am keen to know which is better and what industry needs more these days ...

Hi all.

I write code:

<br />
CStringArray a1,a2;<br />
. . . . .<br />
. . . . . <br />
for(int i=0; i < a1.GetSize(); i++)<br />
	a2.Add(a1.GetAt(i));<br />
<br />
        a2.RemoveAt(Sel);//Sel is integer and 0 <= Sel <= a1.GetSize()<br />
	a2.FreeExtra();<br />
<br />
if(a1.GetUpperBound() == a2.GetUpperBound())<br />
		return;//and it come here<br />

My progrum tell me that this string are equal.

Can help?

I can see there are no elements in a2. Probably, there are no elements in a1,too. In this case
GetUpperBound returns -1. Which cause equality between these two.

I agree with prasad_som. This is easy to test without your mystery ". . . ." lines of code:

CStringArray a1,a2;
 
a1.Add(L"String 1");
a1.Add(L"String 2");
a1.Add(L"String 3");
 
for(int i=0; i < a1.GetSize(); i++)
   a2.Add(a1.GetAt(i));
 
a2.RemoveAt(1);
a2.FreeExtra();
 
if(a1.GetUpperBound() == a2.GetUpperBound())
   return;  //doesn't get here

listboxitems with ids????

Hello,
i have some data from a database, like this:
ID NAME
1 Micheal
2 Thomas
3 Michael

i want to read this from the database and put this data into a listbox.
the listbox entries look like this:
Michael
Thomas
Michael

how can i determine for example if i select the second "Michael" that this is the "Michael" from the database width ID = 3

is it possible to give the listbox-items id numbers like in html???

thanks

I wouldn't like to compare with HTML, but you can give list box items IDs.

int AddStringWithIDToListBox (CListBox &lb, CString s, DWORD dwID)
{
    int nSel = lb.AddString (s);
    if (nSel == LB_ERR)   return nSel;
    return lb.SetItemData (nSel, dwID);
}

You can get the ID at a later time with GetItemData (nSel) etc. The reason for the two step adding, then setting, is that you may have a sort style on your listbox - so insert order != order in list box.

I hope this help,

Iain.
