How to update a view from toolbar in the right way !

CrocodileBuck

Hi, i have got the following questin: I have a SDI Project with a RichTextControl and an editbox in the toolbar. I want to pass the value in the editboc(user input) to a funktion in the document.cpp. I want to load some data in the document and then i want to update te view with this datas. I know how to update the view with datas coming fram the document, but i don't know the right way to pass a value from the editbox in my toolbar to the document !!!??? Here is some code :

**BOOL NEW_cToolBar::PreTranslateMessage(MSG* pMsg)
{
if (pMsg->message == WM_KEYDOWN && VK_RETURN == pMsg->wParam)
{
return TRUE;
}
else if (pMsg->message == WM_KEYUP && VK_RETURN == pMsg->wParam)
{

	CString chrBuf;
	m\_Ctrl\_EDIT.GetWindowText(chrBuf); //<-- The Value
// 	MessageBox(chrBuf, chrBuf ,MB\_OK);


	//((CMainFrame\*)AfxGetMainWnd())->GetActiveView()->GetDocument()->UpdateAllViews(NULL);

    return TRUE;
}
return false;

}**

**void CApplicationView::OnUpdate(CView* pSender, LPARAM lHint, CObject* pHint)
{
CTheReaderDoc *pDoc = GetDocument ();
CRichEditCtrl &rCtrl = GetRichEditCtrl();
rCtrl.SetWindowText (pDoc->m_cstrAusgabe);

rCtrl.SetFont(pDoc->m\_ptrFont);
rCtrl.SetModify(TRUE);

}**

Or is it better to pass the Value directly to the View without using a document ?:confused: And when yes, how can I do that ? Please help me ! Many thanx Croc

You have loads of ways to do this, really, depending on your application. What it looks like you should do is have a function in your document, eg:?

BOOL CMyDoc::UpdateSomeTextField (CString s)
{
if ( !some validation here )
return FALSE;

m\_KeepString = s;
UpdateAllViews (NULL);
return TRUE;

}

and in your PreTranslateMessage function, call this member function. This will decouple your document from the toolbar, and remove the view from the equation. Also, CFrameWnd has a function GetActiveDocument which will be a bit safer for you - and may make it easier when you move to an MDI model (if you choose). Iain.

Hi Mr.Clarke, thank you very much for your reply. I added this to the document.h:

**.
.
.
.
public:
CString m_KeepString;

public:
BOOL bUpdatetextField(CString);**

And this in the document.cpp:

**BOOL CDocumentDoc::bUpdatetextField(CString s)
{
m_KeepString = s;
UpdateAllViews(NULL);

return TRUE;

}**

But how can I call the bUpdatetextFiled from my toolbar :

**BOOL New_cToolBar::PreTranslateMessage(MSG* pMsg)
{
if (pMsg->message == WM_KEYDOWN && VK_RETURN == pMsg->wParam)
{
return TRUE;
}
else if (pMsg->message == WM_KEYUP && VK_RETURN == pMsg->wParam)
{

????????? function call ???????????

// ((CMainFrame\*)AfxGetMainWnd())->GetActiveView()->GetDocument();


    return TRUE;
}
return false;

}**

Err, some of us go home, and have a life... Try:

CMainFrame \*pMF = STATIC\_DOWNCAST(CMainFrame, AfxGetMainFrame ());
CMyDoc \*pDoc = STATIC\_DOWNCAST(CMyDoc, pMF->GetActiveDocument ());
pDoc->UpdateMyField (s);

And check the debugger as you go, as this is from memory. Iain.
