In A as the others have said. It is not a good idea to use SendMessage between threads as you are asking for a deadlock to come knocking on your door.

Why does it flicker sooo much inside a CMainFrame()...?
Do I have to set the CMainFrame() to WS_CLIPCHILDREN..? Should I make sure the CMainFrame() returns false inside OnEraseBkgnd()...?
How can I get rid of the flicker...?
Thank u muchly

You mean like CXImage, FreeImage or GDI+ ? All three are documented here on CP.

I have the following code:
In CMainFrame::OnCreate() function:
...
m_pCbRooms = (CComboBox*) CComboBox::FromHandle(::GetDlgItem(hBar, ID_ROOMS_COMBO));
...
I also have the following function in the CMainFrame class:
void CMainFrame::UpdateRoomList(const CMeasureData* pMeasureData, int nCurrentRoom)
{
ASSERT_VALID(pMeasureData);
ASSERT(nCurrentRoom >= 0 && nCurrentRoom < pMeasureData->GetRoomCount());
ASSERT(m_pCbRooms != NULL);
m_pCbRooms->SetRedraw(FALSE);
m_pCbRooms->ResetContent();
for (int n = 0; n < pMeasureData->GetRoomCount(); n++)
{
const CRoom* proom = pMeasureData->GetRoom(n);
ASSERT(proom != NULL);
m_pCbRooms->AddString(proom->GetDescription());
}
m_pCbRooms->SetCurSel(nCurrentRoom);
m_pCbRooms->SetRedraw(TRUE);
m_pCbRooms->Invalidate();
m_pCbRooms->UpdateWindow();
}
When I call this function in the constructor of my CDocument class it works fine, but when I call this function in some CLICK-Event function, there is a ASSERTION in "afxwin2.inl" in line 120.
In the CLmsPPCDoc::OnNewRoom() event (ASSERTION):
...
((CMainFrame*) AfxGetMainWnd())->UpdateRoomList(m_pMeasureData, 0);
...
What's wrong?

The ASSERT seems to imply that m_pCbRooms does not point to a created window when CMainFrame::UpdateRoomList is called.

For my MDI application Framework I normally have a Single View . i.e On a File New i get another instance of the View class .
Now I want to achieve the task of displaying two views at once. I.e when the user clicks on File--> New , user should see two view Windows . How should I do this .
All i could think of was to Add to the Document template the different views
CMultiDocTemplate* pDocTemplate;
pDocTemplate = new CMultiDocTemplate(IDR_VIEWTETYPE,
RUNTIME_CLASS(CViewTestDoc),
RUNTIME_CLASS(CChildFrame), // custom MDI child frame
RUNTIME_CLASS(CViewTestView));
AddDocTemplate(pDocTemplate);
pDocTemplate = new CMultiDocTemplate(
IDR_VIEWTETYPE,
RUNTIME_CLASS(CViewTestDoc),
RUNTIME_CLASS(CChildFrame), // custom MDI child frame
RUNTIME_CLASS(View1));
AddDocTemplate(pDocTemplate);
Now on a File New I need to show both the Views ! How to do this ? Please Help

Use the WS_MAXIMIZE flag in PreCreateWindow()

The button you press is returned from DoModal. Check if it's IDCANCEL, and if it is, start again.
From memory there is something on MSDN about building wizard type apps, I don't remember anything else, but you should search MSDN, it could be helpful.

When you click on cancel button, it returns IDCANCEL, check this value using coditional statements, if it is then come out of loop/application/return to the begining

In PreCreateWindow(), remove the FWS_ADDTOTITLE style:
BOOL CMainFrame::PreCreateWindow(CREATESTRUCT& cs)
{
cs.style &= ~FWS_ADDTOTITLE;
}

Thanx Mike, just what I was looking for...
I thought it was something like that, but I couldn't find anything in MSDN...I was actually looking for a virtual inside CDocument(), but I had littel luck there too...
Thanx again!

A quick google search brought this up:
Microsoft outdid themselves when they designed MFC such that applications are automatically named according to the document view paradigm. When you use MFC to create either an SDI or MDI application, your main window is probably called something like "Untitled - MyApp." If you don't particularly care for the document view paradigm, other than perhaps wishing to benefit from the separation of user interface and program core, then you're left in the dark...
To get rid of the "Untitled" alone, you can override the CDocument virtual function "SetTitle" as shown below.
void CMyDoc::SetTitle(LPCTSTR lpszTitle)
{
CDocument::SetTitle("MyTitle");
}
This will produce a main window title of the type "MyTitle - MyApp". But perhaps all you want is "MyApp".
You can set the main window title from just about anywhere in your application using the statement shown below.
(AfxGetMainWnd( ))->SetWindowText("MyApp");
The problem with this approach is that MFC in its infinite wisdom will reset your window title to the "Document - App" default as soon as a document object is constructed. If you care to change MFC's default behavior ( not advised ) look up WINMDI.CPP; it's the culprit.
Finally, you can overwrite the CFrameWnd virtual function "OnUpdateFrameTitle" in your apps CMainFrame class. Bud Milwood, a friend of mine, pointed out the function's very existence when I was loosing my sanity browsing the MFC online help. Don't try to look up "OnUpdateFrameTitle" in the Microsoft Developer Studio online help. It's not there. So use it merrily, but use it wisely, subsequent versions of MFC may not support it. The following code snippet shows how...
void CMainFrame::OnUpdateFrameTitle(BOOL Nada)
{
// get app name from string table resource
//----------------------------------------
CString csAppName;
csAppName.Format(AFX_IDS_APP_TITLE);
// Set caption of main frame window
//---------------------------------
SetWindowText(csAppName);
}
Another and probably safer method has been brought to my attention by Stephen Michael Schimpf at CyberSky.Simplenet.Com. You can modify the window style in 'PreCreateWindow' as follows:
BOOL CMainFrame::PreCreateWindow(CREATESTRUCT& cs)
{
cs.style &= ~(LONG) FWS_ADDTOTITLE;
return CFrameWnd::PreCreateWindow(cs);
}

That seems like the most sensible approach...
