I had a similar issue, but I took care of it by only having one menu. When no document is loaded,
a lot of the menu items are gray... But my application only deals with one type of document, so
that solution may not be suitable for you.

I was trying to avoid having to create a second menu with the item removed but in the end I chose that route. So in InitInstance, one of the menus will appear according to my criteria. Thanks for responding though.

I am trying to hook to a process.
i use "CreateProcess" method to create process as WinWord.exe, MSPaint.exe
etc....
then i use a hooking (using SetWindowsHookEx method) with the call
WH_CBT and in the proc i try to catch HCBT_CREATEWND and see if it is the main window.....
this all means that i need to hook the creation of the process i have just created and retrieve a handle HWND to its main window
it works ok with MSPaint but for word and excel and power point for example, it don't work at all....it seems that the hook occurs right after the main window was already created that is why the message WM_CREATE never cought....
can any1 help?
am i doing it wrong? is there a better way?

See here on how to do this.

StartButton.SetWindowText("TEST");
Should be:
starthandle = FindWindowEx(Window->GetSafeHwnd(),NULL,"Button",NULL);
::SetWindowText(starthandle, "TEST"); However, this will not work as intended as the Start button's text is not drawn in the normal fashion.

The compiler is telling you exactly what the problem is. You are trying to use CWnd::SetWindowText() which does not take 2 parameters.

Hi everyone.
I'm writing a service that periodically launches a GUI program. I want to check to make sure someone is logged on to the computer before i launch the program so it can interact with the desktop. Is there any easy way to do this? Thank you very much.

How about NetWkstaUserGetInfo()?

if u use OpenInputDesktop() and it returns NULL then the interactive desktop is not available. ie: no-one is currently logged on or "using" the computer.

Hi,
I program with Visual C++ .NET 2003.
I have an application that I want to quit if a specific date is passed. (the user will not choose Quit in the menu)
I want to terminate the application in the OnClose member function of my CApplicationView class.
I have tried with various methods like PostMessage(WM_DESTROY, 0, 0) or PostQuitMessage(0) without success.
Does anybody have suggestions ?
Thanks,
Claude

The correct method is PostMessage(WM_CLOSE).

You can try PostMessage(WM_QUIT,0,0) too.

I don't think you can count on the connection remaining open for that long a period if the app is on a different machine than the database. what I did in one of my apps was to check for that specific error that indicates the connection is not open, then try to re-open the connection without sending the user any indication. if the re-open fails, then I let the error message continue as usual

Hi,
I have an ATL COM object with DECLARE_CLASSFACTORY_SINGLETON
is there a way to access the singleton instance inside the serverdirectly?
(currently I'm using CoCreateInstance, but the registry/DllGetClassObject round trip seems not necessary)

 I created two static horizontal panes using CreateStatic() function of CSplitterWnd class. The view class of the top pane is derived from CView and the bottom pane from CScrollView. The message mapping of the menu items is performed in CMainFrame as it cannot be done directly from both the view classes(Atleast it seems like that). The problem is wheni call Invalidate(TRUE) in one of the functions of the View class it gives a runtime error.
BOOL CMainFrame::OnCreateClient(LPCREATESTRUCT ,<br />
CCreateContext* pContext)<br />
{ <br />
VERIFY(m_wndSplitter.CreateStatic(this, 2, 1));<br />
<br />
VERIFY(m_wndSplitter.CreateView(0, 0, RUNTIME_CLASS(CTitleView),<br />
CSize(100, 100), pContext));<br />
VERIFY(m_wndSplitter.CreateView(1, 0, RUNTIME_CLASS(CTrialView),<br />
CSize(100, 100), pContext));<br />
m_wndSplitter.SetRowInfo(0,50,50);<br />
return TRUE;<br />
}
As u can see from the above code i created a splitter window. CTitleView is derived from CView and CTrialView from CScrollView.
void CMainFrame::OnFileOpen() <br />
{<br />
m_pTrialView.OnFileOpen();<br />
}
m_pTrialView is an object of CTrialView. It is used to call the function FileOpen in CTrialView.
void CFaceRecognizerView::OnFileOpen()<br />
{<br />
Invalidate(TRUE);<br />
}
void CFaceRecognizerView::OnDraw(CDC* pDC)<br />
{<br />
CFaceRecognizerDoc* pDoc = GetDocument();<br />
ASSERT_VALID(pDoc);<br />
if(flag==1)<br />
AfxMessageBox("HI");<br />
}
This is where the error comes. My aim is to access the OnDraw() function. Hopw someone can help me out of this

When working with Doc/View framework, is it better to call UpdateAllViews from doc objects instead of trying to repaint views themselves.
