I developed one application which adds the icon to System tray. When I press Start (in menu) it will start.

But in our application ,.->

When I press 'X' in the dialog I don't want to terminate
the application .

When I press Shutdown (which is a menu item when I press on right click on icon )It has to shutdown.

Plz How to handle code in OnSysCommand ., When I press 'X'
in dialog.(Application Should not be terminate.Let it be there itself in the system tray )

hi all

I have an application that creates a ms word document. I need to include the page number. I have posted a similar question last week but this one is more to the point.

I have done my research and according to msdn, the function to use is

expression.Add(PageNumberAlignment, FirstPage)

WdPageNumberAlignment

constants:
wdAlignPageNumberCenter, wdAlignPageNumberInside, wdAlignPageNumberLeft, wdAlignPageNumberOutside, or wdAlignPageNumberRight

I have no problem calling out the header and footer pop up... navigating between header and footer but I am still unable to add the page number. The above function uses the vb constants. Anyone know the c++ equivalent for these? I tried using it in C++ but its a undeclared identifier.

Thanks in advance.

I haven’t tried word automation in C++ yet. In vb it’s a breeze. Smile | :)

Here are some articles on the MSDN.

This one shows how to get the Word DOM (Document Object Model). The function you seek should be accessible here.

watching unicode strings during debugging

I use Visual studio 6, and when I am debugging I can only see character pointers (char *), but for wchar_t pointers I only get the address in the watch/debug windows and I will have to check out the memory explicity. Is there any direct way of seeing the wide char strings during debugging?

thanks

Is that the only way to watch unicode variables? It is too much of work viewing a bunch of variables every time copy/pasting the memory location.

Or atleast, is there a way to open multiple memory windows to watch multiple variables?

What do you mean ? When I have the following code, I can see "buffer" in the watch window.

wchar_t buffer[25];
memset((void*)buffer, (int)'\0', 25);
memcpy((void*)buffer, _T("Hallo"), sizeof(_T("Hallo")));

The default symbol for a string is s. Use su instead. There's also st which can be used for ANSI or Unicode depending on what you have in autoexp.dat. These symbols are used in the Watch window after the variable that is being watched.

I seem to remember that there's an option ( a checkbox) somewhere in the preferences that let you see unicode strings in the debugger.

m_pMainWnd is NULL in CWinApp::Run

Hi,

In my app::InitInstance()

<br />
{<br />
  ...<br />
  CMyDlg dlg;<br />
  m_pMainWnd = &dlg;<br />
  dlg.DoModal();<br />
  <br />
  return TRUE;<br />
}<br />
<br />
The 'CMyDlg' has an internal timer that gets activated after 1 second, and starts executing some actions.  After done, the timer is killed and 'CDialog::OnOK' is called.  This gets the dialog closed.<br />
<br />
In the app i need to return TRUE, else i got exit code != 0.  But now, i get this ennoying warning:<br />
Warning: m_pMainWnd is NULL in CWinApp::Run - quitting application.<br />
<br />
Any way to get this (annoying) warning out of the program?<br />
<br />
Greetings,<br />
Jens

"Typically, you set this member variable when you override InitInstance. In a worker thread, the value of this data member is inherited from its parent thread."

Can you show the complete code for InitInstance up to dlg.DoModal();?
Also, why are you writing to this variable?

Dialog based apps must return FALSE from their CWinApp::InitInstance function.

I tried to return false, but then the exit-code of the process is '1'. The exit-code needs to be '0'. I removed the m_pMainWnd = &dlg; line alsoo.

You need to use:

BOOL CMyDialog::InitInstance()
{
    return FALSE; // so that the application's message pump doesn't start
}
 
int CMyDialog::ExitInstance()
{
    return 0; // the application's exit code
}

HideWindow

11-Sep-05 20:43

Hello,

I created a custom scrollbar. I need it to be hidden when the page size is larger than the range.

I used void ScrollBarEx::OnShowWindow(...) fn (mapped) to track the visibility of the scrollbar wnd.

I got the message callback to this fn when the scrollbar wnd is being shown.

But I can't hide the window from fn.

void ScrollBarEx::OnShowWindow(BOOL bShow, UINT nStatus) 
{
	// just for testing
	ShowWindow(SW_HIDE);
}

What steps should I do?

For that you have to enumerate the values under the RUN subkey....

or if you want to know who to distinguish in your program then This link quite similiar to that :-ow to start at Program which start Hidden on Windows startup but Visible other wise?[^]
