What does having a class or struct have to do with being able to use MoveWindow() or SetWindowPos()?

If u dont have a class and u use MoveWindow() the only thing that will move is the dialog u must specify that u want the image.
how do u do that?

Perhaps you are confused as to what MoveWindow() does. It changes the position and dimensions of the specified window, whether that window is a dialog, control, or a frame. If the window in which you are wanting to move has child windows (e.g., dialog having controls), all of them are moved too.

Hi guys,
Can anybody give me a explicit explanation about what is a HWND(handle to a window) , what does it differ from a CWnd object ?? Please provide examples if you can.
I've searched in MSDN but could not get enough information
Regards ,
Nick

I think it's like this: An HWND is a number (handle) to a window (dialog, edit box, etc) that is used by the Windows operating system to refer to the window specifically. CWnd is just an MFC class that encapsulates a registered window class and its handle. You could just as easily make up a class called CMyWindow and in the constructor have it call the Windows API to create a window of the type you want (button, for instance) in your class's constructor, then have the HWND be a property of your class. CWnd is just an encapsulating class, as is CListBox, CComboBox, etc.

Thanks for reply,
So is a HWND smth like : "CWnd object - template resource"  .
Does it mean that if i have a handle to a window ,
i can use all methods declared in a CWnd for this window???
sorry i don't get it

Well, CWnd is an MFC class. You can get an HWND to a window just using the Windows API to create a window, then registering it. If you're using a CWnd class, you can just use the methods of the class; it takes care of all the HWND stuff for you (usually). So if you're using a CWnd-derived object, you probably don't need to use an HWND

A handle is nothing more than a token that an application can use to identify and access an object such as a device, a file, a window, or a dialog box.
See here for what CWnd is and is not.

You can get the CWnd (or the corresponding class) pointer from the handle by using FromHandle(HWND hWnd) so you'll be able to use the advantages from the 2 ways.

CWnd is wraps the Window handle and window handle related API's into a single Class.

Override the WM_LBUTTONDOWN message handler , like this :
void CYourClass::OnLButtonDown(UINT nFlags , CPoint point)
{
SendMessage(WM_NCLBUTTONDOWN,HTCAPTION);
}

It should work. Otherwise use GetItemData() which returns LVITEM structure, it has a member variable which displays the item text.
Work hard and bit of luck is KEY to SUCCESS

What kind of reply is that? Still as useless, but NOAA would have been better.

Some years ago I developed a web application that displayed weather forecasts from different countries/cities. We got the information from XML files served periodically by Reuters. You can do it as well from VC++ using MSXML.
I don't know if Reuters still serve these files but there are other that does.
I hope it helps,
