I created a Smart Device MFC SDI application in VS2005. I've got some files with names like this: MyApp.cpp, MyAppDoc.cpp, MyAppView.cpp, MainFrm.cpp. There are classes in these files. In MyApp.cpp there is a class called CMyAppApp. In MyAppView.cpp there is a class called CMyAppView. In MainFrm.cpp there is a class called CMainFrame. How do I call public methods in CMyAppView and CMainFrame from CMyAppApp? How do I get hold of instances of the classes so I can access the methods? I don't want to use "new" on CMainFrame. This would create a new form. I want to get hold of the handle to the existing form and view (CMainFrame and CMyAppView). I can't find any good pointers in afxwin.h.

There are no instances of classes (objects) until you create them.
You can't access non-static methods of a class without an object.

Where do these existing windows come from if you don't create them?

MFC has functions to to get at those instances like, AfxGetMainWnd() or something
Then the CFrameWnd[^] class has functions to get Views like GetActiveView()

If I understand you correctly then you've already wizard-generated code creating such windows. You may to call AfxGetMainWnd to get a pointer to the frame window (possibly you need to cast it) and the call its GetActiveView (and, again, cast it).

Recently I reinstalled visual c++ 2008 Express edition and ever since then, when I open a project, all the source files within the project no longer automatically restore themselves to their previous state. This question isn't very clear so lets pretend I had the files main.cpp, d3d.cpp, and d3d.h open when I last closed my project. When I open this project again, none of the source files will open with it. I have to manually open all the source files (which can be quite tedious for large projects). Previous to reinstalling, the files main.cpp, d3d.cpp, and d3d.h would all automatically restore themselves in this particular example.
I've searched through the options menu but couldn't find a setting for it

Now I need to write a dll witch COM interface, so that the asp application can use it.
The COM object will have a window. Can asp application show the window created by the COM object?
The problem is:
My COM knowledge is only from the book <Inside COM>, almost no practical experience.
However I can write regular dll (common interface, not COM).
Is there any quick guide for implementing such a COM object?
Thanks very much.

Try this oldie good book about COM Developer's Workshop to COM and Atl 3.0, there are also many good articles here in CodeProject, but this book is a good introductory tutorial.

Thanks, but I don't not have enough time for a book now.
Because of the need in my job, time is limited,
so I need a quick way to implement a simple com object.

Why don't you try creating a simple COM component and see if can it be called in ASP.
read this link COM[^]
The essence of COM is a language-neutral way of implementing objects that can be used in environments different from the one they were created in, even across machine boundaries
Check this section of CP for examples and niformation

Hi,
I want to know how Visual C++ experts implement these complicated logical relations between visual components of a form.
For example when user switch between different radio buttons and you need to en/disable other components or some other tasks.
Actually I need some APIs (like EnumChildWindows) or some approaches(which I don't know any!) to make it more covnvenient to do such boring tasks!

Hello everybody,
in my program I dynamically add up to four CRichEditCtrl elements to a dialog. So far no problem. For some functions (e.g. search function) I need to know which control holds the focus.
How can I determine the active RichEdit control?
Greetings

That means you have handle to all of them.
You can use Getfocus() and check handle returned by it against the handles you have.
I hope it helps.
Regards,
Sandip.

Hi Sandip,
I tried this already, I compared GetFocus() with GetDlgItem('ID'), but it didn't work. They returned two different handles...
For 'ID' I inserted the number I used to create the CRichEditCtrl. Perhaps this is the problem?!
CRichEditCtrl *pRichEdit = new CRichEditCtrl;
pRichEdit->Create(WS_CHILD | WS_VISIBLE | WS_VSCROLL | WS_HSCROLL|
ES_MULTILINE | ES_READONLY, rectRichEdit, this, 2000+i);
m_oaAllRichEditCtrl.Add(pRichEdit);
Greetings

I dont think it can be a problem
But you can verify using GetDlgCtrlID() that id you passed is getting set correctly..
Instead of comparing handles you can also use
GetDlgCtrlID and compare the ID's..

Sandip.

Hello Sandip,
thanks for your help so far - I think we are getting closer. I tried it with GetDlgCtrlID() now and it returns '0' all the time. It obviously looses the focus as soon as I click on the search button.
Is there a flag for it I need to set in the Create() method?
Greetings

Ohh i got the problem..
I can think only one solution at this time
1. Derive your own class
2. Handle LostFocus
3. Set some variable in lost focus handler to identify the rich edit ctrl
4. Check this variable in button click??
Or you have some thing else in mind??
Regards,
Sandip.

Hi Sandip,
I'm afraid I don't have a easier or even better solution 
Thanks for your help!

GetFocus() returns an HWND, which should match the HWND member of pRichEdit.

Hello DavidCrow,
the problem is obviously that the RichEditCtrl loses the focus as soon as I click on the button and so I can't compaire GetFocus() with the pointer anymore.

Why you are just now getting around to mentioning this?
Given this new bit of information, you'll need to keep track of the edit control that had focus last, which is something that WM_SETFOCUS tells you. If you don't like that approach, then each time an edit control gains focus, assign its id, window handle, or CWnd object to some variable that can be compared against later.
I suspect there is a more elegant way of doing this, but with the lack of information provided, I can't say for sure.
