hmmm I'm not sure - those variables should be in the C runtime (CRT) library.
I'm wondering if you're trying to make an MFC app with Visual Studio Express Edition.
That won't work.

As making Libcmtd.lib - ignored (at linker) coused this problem...

Possibly. Try removing it. Also maybe make sure Ignore default libraries options are set to no.
You can also create a similar project from the wizard and look at its settings to give you a
starting point.

hi all
topic says it how can i do something like :
this ist NOT working but what ever i try i ending always by this problem -->
class1.h<br />
<br />
#pragma once<br />
<br />
ref class class1<br />
<br />
{<br />
<br />
public:<br />
<br />
class1(void);<br />
<br />
class2^ c2;<br />
<br />
};<br />
<br />
.cpp<br />
<br />
#include "StdAfx.h"<br />
<br />
#include "class1.h"<br />
<br />
#include "class2.h"<br />
<br />
class1::class1(void)<br />
<br />
{<br />
<br />
}<br />
<br />
<br />
<br />
class2.h<br />
<br />
#pragma once<br />
<br />
ref class class2<br />
<br />
{<br />
<br />
public:<br />
<br />
class2(void);<br />
<br />
class1^ c1;<br />
<br />
};<br />
<br />
.cpp<br />
<br />
#include "StdAfx.h"<br />
<br />
#include "class2.h"<br />
<br />
#include "class1.h"<br />
<br />
class2::class2(void)<br />
<br />
{<br />
<br />
}

Add forward declarations to the header files:
class1.h
#pragma once
ref class class2;
ref class class1
{
public:
class1(void);
class2^ c2;
};
.cpp
#include "StdAfx.h"
#include "class1.h"
#include "class2.h"
class1::class1(void)
{
}
class2.h
#pragma once
ref class class1;
ref class class2
{
public:
class2(void);
class1^ c1;
};
.cpp
#include "StdAfx.h"
#include "class2.h"
#include "class1.h"
class2::class2(void)
{
}

How to copy data from one listview to another?
cheers

The last time you asked this, I told you and you didn't reply. The post is still visible on the board !!!
I assume asking here again means you ARE using C++/CLI and not just C++. OK, not many people are, but as the .NET framework is always the same, I recommend one way to find out about WinForms stuff is to look for C# help and apply it.
Like I said before, WinForms list boxes have an Items collection, you can't just copy items between them ?

A Managed C++/CLI project? If not, you're posting on the wrong message board.
What is a ""file system " project"?

Even if you are in the right forum, this is a place to ask for help with your code. People who ask for full projects rarely have any luck, unless that project already exists on this site.

Hi,
I'm struggling with a problem. I want to catch a 'WM_COPYDATA' event that occurs in a C# application.
I send a data from a C++ application. The bridge is correctly done I think.
So, sometimes it works, usually when my C# application is active.
But most of the time, it doesn't work, because when trying to catch the appropriate WM_COPYDATA message in WndProc overrided method of my C# application, the program stays catching a couple of other messages like: WM_WINDOWPOSCHANGED, WM_ACTIVATEAPP, WM_NCACTIVATE, WM_ACTIVATE and so on.
Doing so, it almost never catch the WM_COPYDATA message that I sent from my C++ application.
Can you help me please ?
Thanks.
P.S.: I catch messages in my C# application like this:
protected override void WndProc(ref Message m)
{
string g = m.ToString();
if (m.Msg == WM_COPYDATA)
{
// instructions.
}
}

Ok Im not exacly a newbie I have read a book alomst front to back on C++ (C++ With Out Fear, Brian Overland) and I do not know what to do next. I really wanna make something, I have had a intrest in C++ since I was like 11 (17 now) I was never really good in math or real problom sovling but it helps if its something I can actually interact with like a lab book or something. I am self-teaching myself and I am really tired of reading. I took a break for like a month an here I am I REALLY want to learn this and Im willing to do really about anything, and I know it will take time but Im hoping to be able talk make real programs soon. Well Im a senior in hight school to graduate in like 3 weeks so I have time to dedicate...I know alot about computers so if someone that knows some stuff about C++ help me like point me what to do next, or good interactive stuff or something I would really like that, you can ether reply here or AIM\e-mail at cgsarebeast@drivehq.com.
Thanks a ton,
JD

Start with some programs that use cout/cin to take input, display output to the console. Something easy would be a math program that asks you for a few numbers, asks you for the operation, and then performs the operation on all the numbers.
If you're just starting out, then you probably won't be looking at any Managed C++, unless you want to work with a GUI (but I wouldn't advise getting to that until you have a better handle on the basics).

I pretty much have a handle on the basics. An I kinda do wanna do somesort of GUI but Idk were to start on that.....
Thanks,

He was telling you that you're in the wrong forum. C++/CLI is not plain C++. You want the Visual c++ forum. If you want to write GUI code in C++, you need to learn MFC, probably. You can use C++/CLI and Winforms, but it's not pretty, and not many people use it.

This forum is for C++/CLI questions. Lots of people make the mistake, despite the notices on the subject in the header of the forum. I guess they gloss over what they don't know
Frogboy181 wrote: I dont want Visual C++ ether
Why not ? It's the forum for 'standard' C++ questions, although the focus is on the Microsoft compiler, and GUI related questions tend to be MFC. The C++ standard has no provisions for any sort of GUI. So, you need to choose a vendor specific library if you want a GUI. MFC is the most popular/common one, if you're coding for windows. If you're coding for Linux then yes, there are probably better places to ask. MFC is sort of on it's last legs, however, C++/CLI/Winforms development is pretty rare, and not a good path to go down.
Frogboy181 wrote: If ur gunna say this post is n the wrong spot or flame me n any way leave it..
Why do you think I'm telling you it's in the wrong spot ? It's because you're in the wrong place. Look around you. 50% or more of replies in this forum say 'you're in the wrong place'. Look at the dates, then look at the Visual C++ forum. This forum is a bit of a ghost town. I am trying to tell you that if you ask in the right forum, you'll get more help.
Although your question is super vague. I'd recommend considering C# if you are hoping to write GUI apps for windows, it's just easier to find resources, and easier to use/more powerful.

Hiya
I would like to know 2 different methods of image resizing. One simple and one complex.
And then i have to implement those methods via programming in C++.NET.
And it would be great if some one could refer me some source code to understand it in detail. I am newbie to Image Processing.
Thanks a lot....

What methods are these. Well is the complex one bilinear interpolation method.
If its not then is it possible for you to tell me with bilinear interpolation one. And yeh it would be great if you could provide me with few good links aswell to underrstand the theory behind it...
As i have to compare the both methods...and point out advantages n disadvantages of both...
