Yes it helps for system windows..

in my SDI appln,

CWnd* pWnd = CMainFrame::GetActiveWindow();

pWnd-> doesnt have setsyscolor or getsyscolor.

It's a api function, just call ::GetSysColor/::SetSysColor.
Use parameters like:

COLOR_GRADIENTACTIVECAPTION<br />
COLOR_GRADIENTINACTIVECAPTION

AFAIK, if you handle OnNcPaint, you need to do everything (redraw everything )

(but I might be wrong).

u r right ..if i handle NCPAINT i got to redraw each and evrything in title bar on my own.
Instead iam looking for some solution from which i can change color of Title bar without disturbing caption text,icon,standard buttons.

yes i searched through and got one MDI application who does exactly what i wanted but he paints customised title bar on exhisting default bar by using subclass technique by Paul DiLascia(MS journal).

my client doesnt allow me to add custom class for this kind of need.

SDI, can't CMyApp::OnFileNew handle the the click message by the button?

int CMyView::OnCreate(LPCREATESTRUCT lpCreateStruct) 
{
  ...
  m_btnNew.Create(NULL,style,rcDummy,this,ID_FILE_NEW);
  m_btnNew.LoadBitmaps(IDB_NEW,IDB_NEW_DOWN);

hi,

then u have to map the WM_COMMAND for the Button Id in following way. ON_COMMAND(ID_FILE_NEW,CWinApp::OnFileNew)

thanks

It's there in CMyWinApp as part o fthe framework.
I don't why the message is not pumped there.

Hi,

this is because the BN_CLICKED message is posted into the Parent Windows message queue. that is why the message is not getting into CWinApp.

But CWinApp::OnFileNew is a protected member function, so I couldn't add the following line to CMyView:

ON_COMMAND(ID_FILE_NEW,CWinApp::OnFileNew);

any quick way?

I found the problem,
If a view receives a message it will go through the view's and doc's msg maps, the app's msg map will not be searched.

That's wrong. The code should throw an exception because you try to access the contents of an iterator outside the bounds of your vector.

The C++ standard does not require an exception to be thrown in this case. The behaviour is undefined.

I think your gcc 2.95.3 sucks and you should stop using it right now.

What's the problem ?

Anyway, AFAIK, you can only check for equality on iterators (don't know if that is the case also on vector iterator). This your end loop condition should be:
myIntVectorIterator != myIntVector.end();

EDIT: I tested and you can do that with vector iterators (for list iterators, you can't). Anyway the problem is that you have to stop incrementing your iterator before the end of your vector. So replace <= by <. Otherwise, if you are at the end of your vector (not a valid element), you will still try to access the contents of the iterator (which is invalid).

You are going past the end of the iterator, change the code to something like this:

vector<int> myIntVector;

    // Add some elements to myIntVector
myIntVector.push_back(1);
myIntVector.push_back(4);
myIntVector.push_back(8);

vector<int>::iterator iStart = myIntVector.begin();
vector<int>::iterator iEnd = myIntVector.end();

while(iStart != iEnd)
{
    cout << *myIntVectorIterator << " "; //Should output 1 4 8
    ++iStart;
}</int></int></int>

You can use of DoModal or ShowWindow after you clicked button and then use of MoveWindow.

in-process server considerations

Hello everyone,

Here is the comments from the book ATL Internals about in-process server considerations,

--------------------
Any thread that calls CoGetClassObject or CoCreateInstance must already have joined an apartment, or the call will fail immediately. So, does that mean all objects exposed from in-process servers must be equally at home in single-threaded and multithreaded apartments so that random clients isn't cause harm? Fortunately, no.
--------------------

Does it mean COM client (thread) and COM server no need to be the same type of thread model (e.g. STA, MTA, etc.)?

thanks in advance,
George
