In an Visual C++ 6.0 application, I need to prevent copying the specified file to other directory, but I don't know how to do.
Please help me!!!
Thank you very much!

P.S. If maybe, you can demonstrate an small application about this.
Thank you!

Prevent who ?

You could open the file with CFile and use one of the flag to prevent other processed to access it.

You would need to set this restriction at the OS level.

Create a service which opens an exclusive handle to the file. This will prevent copying and deleting.

Using the mfc CFile class

CString file_name = _T("C:\\AnotherFile");

CFile f;

f.Open( file_name, CFile::modeRead | CFile::shareExclusive );

while(1)
Sleep(1000);

Event Log Question

Hi all,

I would like to know wheter there is any way (using code) in which I can get hold of the system log, in terms of, when Windows has finished downloading updates and needs to restart. See the reason I'm asking is because some of our computer are never used by users, but still need security updates, and in the light that after every update Windows needs a restart, there will be no user to do so. Any suggestion ??

Many Thanks

C:\Windows\system32\config\AppEvent.Evt

How to find out whether my system is 16, 32 or 64 bit ?

I dont know whether there is any window APIs for this. But you can get this information using WMI. check the Win32_Processor class.

Call IsWow64Process() to tell if the OS is 32-bit or 64-bit.

As a hack you could use sizeof(int*) (any type will do, not just int).
Or, sizeof(int) for 16/32.

...cmk

The idea that I can be presented with a problem, set out to logically solve it with the tools at hand, and wind up with a program that could not be legally used because someone else followed the same logical steps some years ago and filed for a patent on it is horrifying.

GDI+ Region and SetWindowRgn

Nishad S10-Sep-07 23:12

10-Sep-07 23:12

Hi,

I have a control which is using GDI+ and window region.

The below code is used for setting the window region.

GraphicsPath gp;
// Some gp.AddArc calls...
Region rgn( &gp );
Graphics g( hdc );
HRGN hRgn = rgn.GetHRGN( &g );
SetWindowRgn( hRgn, FALSE );

And in the OnPaint, the following is used for drawing the border.

GraphicsPath gp;
// Some gp.AddArc calls... (same used for setting the region)
LinearGradientBrush brush( ... );
Pen pen( &brush, 1 );
Graphics g( hdc );
g.DrawPath( &pen, &gp );

The issue is that there is a slight difference between the drawn path and the set region. That means the path is not exactly fit in the window region. There are some gaps in many places. So drawing cannot be perfect. I am seeking for a solution to this, as CDC::FrameRgn do. I cant use this FrameRgn, since I need a gradient coloring in the path.

Thanks in advance.

When you say does not fit, what are the effects?

Do you mean you've drawn the region using GDI and then with GDI+ and they are close but not exactly the same?

Nop... the window region set is a little bit different than the path drawn by using GDI+. So there are some holes (area that's not drawn) in the edges of the window.

I have encountered Access violation reading location with this code:

IConverterSession* sample;
	sample = NULL;
	IStream *istream;
	istream = 0;
	sample->SetEncoding(IET_QP);
	sample->SetSaveFormat(SAVE_RFC822);
	hResult = sample->MAPIToMIMEStm(LPMESSAGE(msgName.c_str()), istream, CCSF_SMTP);
	if (hResult !=S_OK){ 			 		
		throw(HResultException("MAPIToMIMEStm ResolveMsg",0));
	 }

I am really new to this can anyone guide me in making this work?

Thanks a lot,

sample = NULL;<br />
....<br />
sample->SetEncoding(IET_QP);

Guess what will happen when you call a function on a NULL pointer ?
You first need to create an object (do you need to use pointers here, can't you simply create an instance of IConverterSession ?)

By the way, the debugger is your best friend Wink | ;)
