CDocument::OnFileSaveAs is just the function that gets called when you click 'on' the 'Save As' button in the 'File' menu. CDocument is the Class that contains it. Im new too, you will pick it up, just keep trying

How should i load a DOM object in a MFC application?
I've tried with "add class...from a type library" and some classes are attempting to override the corresponding from msxml2.h. So, it doesn't work this way.
Wish for help!

There are multiple examples of this kind of thing available here on CodeProject. However, as in most things C++, the details are rarely easy. In general though:
#include "msxml.h"
#import "msxml3.dll" named_guids raw_interfaces_only
using namespace MSXML2;
IXMLDOMDocument *pDoc;
if ( SUCCEEDED (CoCreateInstance(CLSID_DOMDocument, NULL, CLSCTX_INPROC_SERVER,
IID_IXMLDOMDocument, reinterpret_cast<void**>(&pDoc))))
{
//
// Tell the "doc" that we're not going to load asynchronously.
//
if ( SUCCEEDED(pDoc->put_async(VARIANT_FALSE)) )
{
CComVariant vFile(strFileName);
VARIANT_BOOL vBool;
pDoc->load(vFile,&vBool);
if ( vBool == VARIANT_TRUE )
{
IXMLDOMNode *pNode;
if ( SUCCEEDED(pDoc->QueryInterface(IID_IXMLDOMNode,
reinterpret_cast<void**>(&pNode))))
{
CTreeCtrl *pTree = static_cast<ctreectrl*>(GetDlgItem(IDC_XMLTREE));
HTREEITEM hItem = pTree->GetChildItem(TVI_ROOT);
while( hItem != NULL )
{
HTREEITEM hNext = pTree->GetNextSiblingItem(hItem);
pTree->DeleteItem(hItem);
hItem = hNext;
}
IterateChildNodes(pNode,pTree);
pNode->Release();
pNode = NULL;
}
}
else
CheckLoad(pDoc);
}
pDoc->Release();
pDoc = NULL;
}

Thanks!
And a question: is it allways the best to use "import", instead of creating the classes from a type library?

Using #import is the easiest way I know of to load a COM object. It's my preferred method. You can load the type library of the COM object you wish to load or the DLL itself (which will contain it's own type library anyway).

I'm writing a SDI application, which allows users to create models, and then save them. I've implemented most of the create functionalities, and I'm in the progress to working on saving the models.
The problem I'm having is that when I try to add a message handler for 'Save' or 'Save As' from the menu, they don't seem to work??? I mean, the program doesn't even go through those bits of code??? I've put messageboxes, and breakpoints at different places, but the program just never gets there??? I think, is because of some code the MFC wizard has put there, e.g, built in code when using the wizard to create the project.
For some strange reason, 'File Open' works fine???
Any help would be much appreciated

Could probably help you out but I'd need to see the code. I don't do well in generalities for these kinds of problems. Up to you.

There's a good example (several actually) in the DirectX 8.1 SDK (available from the MSDN Downloads).
Under Samples\Multimedia\DirectShow\Editing. It's called StillCap and illustrates movie and still capture.

Then I guess you'll have to get your hands dirty and rip out the frame grabbing stuff and put it into your app. 
Sorry, but I don't enough about video capture to help much. I just hacked the example I mentioned to get it to behave how I wanted (but I didn't change the video capture functionality).

Hi everybody! 
I need help to achieve a project at work.
My app is a MFC dialog based. I need to access variables and control between 3 modeless dialog. How can I do that. I've tried everything I know.
I have already a lot of work done in both 3 dialogs...
Let me explain what I've done.
- I have 3 templates : IDD_MainDlg , IDD_Dialog1 , IDD_Dialog2
- IDD_MainDlg's class is CMainDlg (Created with the wizard at startup...)
- IDD_Dialog1's class is CDialog1 and then IDD_Dialog2 is CDialog2.
- I've declared :
CDialog1 m_Dialog1;
CDialog2 m_Dialog2;
inside the CMainDlg header file.
- I've created :
m_Dialog1.Create(IDD_Dialog1,this);
m_Dialog2.Create(IDD_Dialog2,this);
m_Dialog1.ShowWindow(SW_SHOW);
m_Dialog2.ShowWindow(SW_SHOW);
inside the OnInitDialog() of CMainDlg;
Let say that I have a CSliderCtrl object called 'm_Slider' declared inside the CDialog2 header file. When I'm in CMainDlg, I can access this variable by typing m_Dialog2.m_Slider without problem or error. Where I'm confused is when I'm inside CDialog1 and want to access m_Slider.
This is the 'best one' of all codes I've tried :
CDialog2* pWnd;
CMainDlg pdlg;
pWnd = &pdlg.m_Dialog2;
pWnd->m_Slider.SetPos(0);
I always get an assertion error. When debugging it always say that there is no handle
_AFXCMN_INLINE void CSliderCtrl::SetPos(int nPos)
{ ASSERT(::IsWindow(m_hWnd)); ::SendMessage(m_hWnd, TBM_SETPOS, TRUE, nPos); }
(m_hWnd is always 0x00000000 )
What can I do to get all the things working well ?!?!?! 
I have a lot of data to pass between theses three dialogs so...
Best regards,
Brind

You're code is not working because the window has not been created yet. Always keep in mind that just because you create an instance of an MFC class such as CDialog (or a derived class), the encapsulated window isn't actually there until you tell the class to create it.
With regards to communicating data between these various dialogs, there several ways to achieve this. If you're simply trying to get initialization data to one dialog from another, you can change the constructor to accept this information. Then in the dialog's constructor, you save this information in member variables and finally use it to init the dialog's controls in either the OnInitDialog or DoDataExchange function.

Hi Tom  ,
I don't understand what you said when you tell that 'the encapsulated window isn't actually there until you tell the class to create it'. Is this because I create my window inside the main window or what? Would you supply me a small example that will point me in the right direction.
Also, my datas to be communicated aren't only to be passed at initialisation of the dialog, they are to be communicated all the time until I stop the app.
Im newbie in C++ so, there's a lot of thing that confuse me!!
Thanks,
Brind

When you instantiate a CDialog, you don't have a window yet. You won't until you specifically tell the class to create its underlying window. In the case of a modal dialog this is done via DoModal. In the case of a modeless dialog, this is done via Create or CreateIndirect. In you situation, you're referring to controls on a dialog that haven't been created because their containing window (the dialog) hasn't been created. Therefore, you'll need to move that code using one of the techniques I described.

What is this function used for?
No seriously, I have been playing around with CFtpConnection, specifically PutFile, and I have found that i need to specify exacly where the file should be placed on the server. I tried to use SetCurrentDirectory but to no avail. The functions returns success but when I just put the file name in PutFile it transfers it to the root. To me SetCurrentDirectory should let me put just the file name(no path) in PutFile.
So my question is. Am I doing it wrong and SetCurrentDirectory should work the way I want it to, or am I suck with PutFile with the Path\FileName.
Thanks in advance

That's definitely strange because I've written a very basic FTP client and it works fine.

It worked perfectly for me, you tried using GetCurrentDirectory and then set the path relatively with SetCurrentDirectory ? What was the error that GetLastError() reports ?
x = GetLastError();
Better put the variable x on the watch window with the modifier hr like this:
x,hr
what the error says ?
See this on this page for a basic ftp tool using wininet :

You need to create a CFormView-derived class via the ClassWizard for each dialog resource that you defined. Then you need to call CFrameWnd::CreateView() for each view. Then use CFrameWnd::SetActiveView() to switch between them.
