i change it but nothing work.

BEGIN_MESSAGE_MAP(CProSeS_SQLTalk_View, CEditView)
ON_WM_KEYDOWN()
END_MESSAGE_MAP()

void CTestView::OnKeyDown(UINT nChar, UINT nRepCnt, UINT nFlags)
{
if (nChar == VK_RETURN)
{

}
CEditView::OnKeyDown(nChar, nRepCnt, nFlags);
}

}
}
return FALSE;
}

So...do breakpoints placed in your view's PreTranslateMessage get triggered?

Java, Basic, who cares - it's all a bunch of tree-hugging hippy cr*p

i already put breakpoints as you said but the Debugger did not go to the PreTranslateMessage().

And you're sure that you are building a debug build?

Are you sure your view class is being used?

yes.

i do not know, how can i check that ? and if it is not being used what should i do?

Have you got some code in your CMainFrame class that you can a) add some code to, and b) guarantee will be executed application's running?

If so, then add a call to the active view's OnKeyDown handler:

GetActiveView()->OnKeyDown((UINT)'a', 1, 0);

Set a breakpoint on that line. When the breakpoint triggers, repeatedly step into the call (it'll call the GetActiveView() methods first, then step back out, then step into the OnKeyDown handler). When you get to an OnKeyDown handler, you can see what the view type is.

i got this error when i wrote this in my CMainFrame class:

GetActiveView()->OnKeyDown((UINT)'a', 1, 0);

error C2248: "CWnd::OnKeyDown" Members of a derived class cannot access private members of a base class.

Stuart Dootson22-May-09 2:09

My fault - didn't realise OnKeyDown was private. Ummm, OK - you need to add (to your view class) an override for a public method of CView. Call that from your CMainFrame. For example, CDocument:

CDocument* CTest_View::GetDocument() const
{
   return CEditView::GetDocument();
}

i have this code in my Doc.cpp

CTestDoc* CTest_View::GetDocument() const
{
ASSERT(m_pDocument->IsKindOf(RUNTIME_CLASS(CTest_Doc)));
return (CTest_Doc*)m_pDocument;
}
it cause a trouble when i add this :

CDocument* CTest_View::GetDocument() const
{
return CEditView::GetDocument();
}

my SDI Application is splitted horizontally to two parts adn i need to get if the Return Key in the upper part being pressed.

There's the salient point - you've got a splitter view between MFC and the view that you want to receive messages.

Where is your splitter created? In the CMainFrame?

Yes.

Right, well I think the splitter window's trapping your return key presses - looking at the splitter window's OnKeyDown handler, it has a case for VK_RETURN.

i do not have OnKeyDown handler, in Test.cpp file i just have
BOOL CTest::PreTranslateMessage(MSG *pMsg)
{
// Do something
}

and in this Function i get the Curosrp position.

why mfc! they are independent of the language you code in eg:C#,C++,java

you can find some examples on Google[^]

You need to google first, if you have "It's urgent please" mentioned in your question.

What do you mean exactly ? You want to learn UML or you want to create a MFC dialog that lets the user draw some UML diagram ?
As already posted, UML is independant of the fact that you are using MFC (or even that you code in C++).
