An Application can have one or more DocTemplates. Each of them can have one or more documents. And each Document can have one or more views. So actually if you want one particular view you will have to have three levels of loops.
Anyway here is a broad outline of how to get a view from Anywhere in the app.
[ccode]
CMyApp *pApp = AfxGetApp();
CDocTemplate* pDocTemplate;
CDocument* pDoc;
POSITION rPos1,rPos2,rPos3;
CView* pView;
rPos1 = pApp->GetFirstDocTemplatePosition();
while (rPos1)
{
pDocTemplate = GetNextDocTemplate(rPos1);
if (pDocTemplate)
{
rPos2 = pDocTemplate->GetFirstDocPosition();
while(rPos2)
{
pDoc = pDocTemplate->GetNextDoc(rPos2);
if (pDoc)
{
rPos3 = pDoc->GetFirstViewPosition();
while (rPos3)
{
pView = GetNextView(rPos3);
if (pView)
{
// check if this is the desired view and do
// your stuff
}
}
}
}
}
[/ccode]
Tell me if this helps.

Thanks for your help.
I think it worked to get the views. I have two views in my application and the while loop goes twice in "while(rPos3)".But what do I write in the if(pView == ???????) how do I know the identifier of my desired view. When I get the correct view how do I access the function setUsers() in this view. The view is named CTableview and I've derived it from CFormView.

try this:
#include "tableview.h"
...
if (pView->IsKindOf(RUNTIME_CLASS(CTableview))) {
CTableview* pTableview = (CTableview*)pView;
pTableview->setUsers();
}
...
CTableview would have to be at least DECLARE_DYNAMIC.
A note: I've used the ol'-fashion casting here ((CTableview*)pView) - I'm sure there's a lot of C++ gurus out there that want you to use static_cast<> or dynamic_cast<> or whatever instead - but I've never figured out which one to use so I stick with the old one.
good luck
Steen.

Regarding casting: there's a nice article on DevX about casting:

It sounds like your design may be in error. In a propelry designed MFC app, there should be no need to call a function like SetUsers() externally from a view.
A view has two purposes:
1) It displays a document.
2) It handles UI commands.
The name of the fuction SetUsers() makes me think that your view is storing data.

Is there another way to solve the problem?
In CMainFrame I handle several menu choices. When a the user clicks in the menu I want the FlexGrid that's a member of CTableView to change. For example the number of colomns and the caption of each row should change when the user make different choices. SetUsers() is public and a member of CTableView, in this function I update the table when the user has pressed a choice called "manage users". I thought this would be the right way to go...call this function from CMainFrame where I handle onManageUsers().
Is the design in error?

If all the processing in OnManageUsers() can be done in CTableView then you should certainly let that class handle the menu choice (i.e. put the ON_COMMAND macro in CTableView's message map instead of putting it in CMainFrame's map). If some of the processing (such as updating the view) is done in the view, while other things is done in the frame you have a couple of options:
( in the code below I deliberately omit all semicolons at line ends - they will probably be translated into smileys 
1) put OnManageUsers in CTableView, and use SendMessage/PostMessage to let CMainFrame do it's thing. You can make a private message (#define WM_MANAGEUSERS WM_APP + 1, for instance). In CTableView:
CTabelView::OnManageUsers()
{
... // do stuff
GetParentFrame()->SendMessage(WM_MANAGEUSERS, (WPARAM)something, (LPARAM)somethingelse)
... // do some more stuff
}
2) put OnManageUsers() in CMainFrame. Let it do whatever modifications is needed. The result of the modifications should somehow be available in the document class (CDocument derivate). At the end of OnManageUsers call the UpdateAllViews method of the document class. If you have more than one document open at a time this method is bad! UpdateAllViews will call all OnUpdate handlers in the view classes. In CTableView, let OnUpdate do the updating of the UI.
3) Let the document handle OnManageUsers() and let it notify the frame and any views.
Hope this helps

It is possible to get a text underlined when you drag the mouse over the text?

Can you be more specific about what type of text you require to be highlighted. Is it on a button? Edit box? etc

Thanks for your interest. It's just a static text. I have a single document with two views and in the left view I have several static texts. The static text are menu choices. When I drag the mouse over the text I want to underline it. When I click on the text I want it to get another color. I managed to get the the text to respond to click by OnLButtonDown() and OnMouseMove() to change cursor.

What are some good ones?
In particular I am looking for controls that would be useful for a touch screen application (pop-up virtual keyboards, etc.), also database aware controls using OLE DB.

I'm adding controls to a dialog, and then I cannot add any more, is there a finite number of controls that I can add to a dialog?? How do I increase this number....??
TIA

IIRC you can only have 255 (or 256?) controls in a dialog resource. If you need more, you must create the controls at runtime.

Is it possible to register multiple file extensions with an SDI application?
I tried doing the following, but this strange box pops up (new document) but if I pick any choice but the first, an error occurs. Should I create a different document class to handle each file extension type? Or is there an easier way?
AddDocTemplate(new CSingleDocTemplate(IDR_FILETYPE1,
RUNTIME_CLASS(CTest2Doc),
RUNTIME_CLASS(CMainFrame),
RUNTIME_CLASS(CTest2View)));
AddDocTemplate(new CSingleDocTemplate(IDR_FILETYPE2,
RUNTIME_CLASS(CTest2Doc),
RUNTIME_CLASS(CMainFrame),
RUNTIME_CLASS(CTest2View)));
IDR_FILETYPE1 is "sdi app\n\n1\nfiles (*.txt)\n.txt\npart 6-1\npart 7-1"
IDR_FILETYPE2 is "sdi app\n\n1\nfiles2 (*.doc)\n.wsf\npart 6-2\npart 7-2"

How can I change the font of a CStatic control?
Thanks,

Hi...
Use the CStatic::GetDC() function to get the device context of the static control.
Then u can use the CDC's font manipulation functions to play with fonts.
Happy coding,
Regards,
Rejeesh

You can use CWnd::SetFont(), and I always use CFont::CreatePointFont() for convenience.
Cheers,
Bob.

Hi,
I am adding an automatically resizable dialogbar into my MFC program. But it can not automatically resize when the window size is changed. Can you tell me the reason and how to implement this? Thanks in advance.

If I throw and catch an exception in VC++ I see something like this in the debug window:
First-chance exception in DF.exe (KERNEL32.DLL): 0xE06D7363: Microsoft C++ Exception.
Is there anyway to prevent this message from being displayed?

There might be a pragma, but what's the problem ?

I would like to get an answer as well. When a server program pops up one of those messages phones start ringing. If it is a regular program, all I usually have to do is clear the error message. If it is a service though, there is no visible message to clear and the only resort is to re-start the computer
