Am I correct to say that I can locate the event log in the following directory:

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

Many Thanks in advance

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,
Jj

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 | ;)

How to detect Internet connection on machine?

Sameerkumar Namdeo10-Sep-07 22:52

I am using CWebBrowser2 wrapper in my dialog based application.
In the OnInitDialog() function I am calling Navigate() function of CWebBrowser2.
If the internet connection is not available on a machine then how can I generally detect that so that I can display some default thing in CWebBrowser2 control.
Can it be detected using CWebBrowser2 ?

Thanks.

At least you can realize a ping on a specific server.
Propably the CWebBrowser2 has this function...

Good luck

Pinging a machine is not reliable. Too many false-positives.

That's right, but in case of no internet connection you have all the time a false result.

But it's anyway the latest possibility LOL

If you have a dial-up, the attempt to query an IP will cause the ISP authentication junk (dialog boxes) to kick in. We tried this back in 2002 and soon realized it caused too many issues on laptops that needed to connect at locations with modems but weren't connected at the time the software was being run.

You need to check the routing table, then maybe attempt a ping after you know there is some network connection.

There are a couple of different approaches to check for network connectivity before attempting to go out and touch another computer.

You mean false-negatives? ICMP-requests to a live server filtererd out by a firewall?
You need to pick a server with ICMP running and not prone to stop that. I use "www.heise.de" for that. A german publisher of computer magazins with a very dedicated opinion on why ICMP-filterung is bad.
