Hi All,
I know the process name. I want to getting notified on the starting/Exiting of that particular process in my program.
Is there any method for this other than repeatedly enumerating all the running processes and checking for that particular process.
Thanx in advance.

You need to read Detecting Windows NT/2K process execution[^](An article on how to get notification from the OS when a process starts ).

Thanks for the reply Hamid.
This articles describes about the development of a Processor Monitoring Application by Implementing a Kernel-mode driver, using the kernel mode driver API PsSetCreateProcessNotifyRoutine().
But I can't use this since I have to implement the Process monitoring in my MFC dialog baesd application.

I'm trying to extract an icon from an exe file. I've managed to find Its raw data within the EXE file; but this raw data differs from a *.ICO file! I mean It's not possible to use an HEX editor to copy the raw data and save It as a *.ICO file. any help?

Thank you masters!

Calculate Date Difference in months

27-Jan-09 19:53

Hi All,

I am writing one function that should return me a difference between given dates in months. I know it can easily be done by getting difference in years, months and days. Then calculate months like

trmMonths = 0;
trmMonths += years * 12;
trmMonths += months;

But i am not sure about what to do with days, because sometimes it may happen that difference between dates would be years = 1 months = 11 days = 28. in this case the difference between dates should be 24months.

Can anyone give me idea on how days can be handled here to get accurate difference?

Thanks,
AksharRoop

Err I'm totally confused by your sentence here. Could you explain a bit better what is the problem exactly ?

Are you using COleDateTime and/or COleDateTimeSpan classes ? This could help you manipulating times.

Radio Button issue in RTL Layout

Alex@9C27-Jan-09 19:51

27-Jan-09 19:51

I have a strange issue. There are 3 radio buttons that are grouped horizontally are showing wrong behavior.
By default two radio buttons are checked and one is unchecked.
When you click on any Radio button it becomes unchecked and the remaining two becomed checked.
The code is working totally fine when there is no RTL support.
However after applying the RTL support the above problem starts to occur.

I have a custom library that draws the radio buttons.

Createprocess and set the window position

Super Hornet27-Jan-09 19:20

27-Jan-09 19:20

Using createprocess I am invoking a dialog based application and from the processid I am getting the HWND of the dailog and then setting the window position, till now it's fine.

The problem comes when we try to invoke a dialog based application(using create process) which has an error in initializing(displays warning or error message)after pressing ok on error message the dialog is invoked for which we are unable to setwindow position because of error message. How can we by-pass the error message and set the position of dialog???

Note: We do not have code for invoked process.

In order to play a wav raw data, you should know more details about its sampling, bit rate, number of channels, etc.

I have removed caption bar of the dialog box, i want a context menu on right click event anywhere on the dialog?

To show context menu on right click, map WM_RBUTTONUP and write...

void CMyDlg::OnRButtonUp( UINT nFlags, CPoint point ) 
{
	CMenu menu;
	menu.LoadMenu( IDR_MENU1 );
	ClientToScreen(&point);
	menu.GetSubMenu( 0 )->TrackPopupMenu( 0, point.x, point.y, this );
	CDialog::OnRButtonUp( nFlags, point );
}

To change the background map WM_ERASEBKGND and write...

BOOL CMyDlg::OnEraseBkgnd( CDC* pDC ) 
{
    CRect rect;
    GetClientRect( &rect );
    pDC->FillSolidRect( &rect, RGB( 255, 192, 0 ));
    return TRUE;
}

Why? You can set the ID in properties.

Here IDR_MENU1 is only a sample. You can give your own menu's ID.
