Is there any way to draw a Region (in GDi+)without using
FillRegion(Brush*,Region*) method?
FillRegion(...) method only fill a region using brush property.
I need to draw only the border of the region not to fill the region.
Pls help............

This intrigued me, as I thought you could simply use a NULL brush, but no.
Can you use the Region::GetHRGN to get GDI (not +) HRGN, then use the ::FrameRgn function? (You'll need the Graphics::GetHDC method too)
Why the FrameRegion function isn't exposed, I don;t know - it's not as if its a new one...

Not exposed? What do you mean? 
FrameRgn() works ok.

I meant the functionality wasn't exposed - or provided. As the Graphics object has a GetHDC method, and the Region object has a GetHRGN method, then I can;t see any reason why there wasn't a
Graphics::FrameRegion (Region *, Brush *, int xThickness, int yThickness);
method too.
I'm an old school Win32 fiddler (even if I can't see a SND_LOOP parameter when its kicking me in the face)
Our's is not to reason why - our's is to code and die.

Well that makes sense. Apparently, without sufficient caffeine, I can't see all those little '+'s
after the "GDI"s so I misread your post, which is why I asked.
For GDI+ I believe they chose to handle this with paths (the GraphicsPath class) instead
(I know I read it somewhere, can't find it...).
This is also why the most complex Region that can be created directly is a rect.
Cheers!

Thank you very much for your reply. I have used NULL_BRUSH but it doesn't work.
I have used Region instead of CRgn because of scalling facility using Region.
According to your instruction i have used following code
CRgn* rGn;<br />
rGn = CRgn::FromHandle(m_pRegion->GetHRGN(g));<br />
CBrush brush;<br />
brush.CreateSolidBrush(RGB(255,0,0));<br />
pDC->FrameRgn(rGn,&brush,10,10);
Now it is working............
Thank you so much...

hi
one of my security related project is having requirement to create a secure service.
that means users should not be able to stop the service.
i have done it using CreateProcess API.
But what more is required is to totally disable the Recovery Actions for the service same as the system critical services like "Event Log" (That enables event log messages issued by Windows-based programs and components) .
i want to make my service same as provided by windows that is "Event Log" or that of WebSence software.
So please make some suggestions for this.
Currently i am looking in the direction of DACL.
if there is any other way then please let me know.
Thanks a lot!

Hi All,

Well, since any message can be reduced to binary data - and IS behind the scenes anyway, you can send any kind of message you want. The processing of said messages is up to you.
Peace!

The problem is as follows:
in a chat system.A and B are client ,C is server. There is only one tcp line between client and server.Client A send data to server C ,then server C transmit data to client B, but can B send data to client A throuth server C at the same time?I think there will be a problem,because B and C are sending Data to each other at the same time.There must be a conflict.My friends think there are no problem ,tcp can deal with it.
so can are a client and a server sending data on the same connection at the same time? or create establish two socket,one for receiving,the other for sending?
Thank you for helping me.

There should be no problem with this at the TCP/IP socket level. The application(s) involved being able to handle sending and receiving at the same time, well that is another issue.

TCP can deal with your problem. What you call 'at the same time' is managed by the lower layers of the network system.

I am using CBitmapButton to display bitmap on the push button.
CBitmapButton m_bitmap;
m_bitmap.Create(NULL, WS_CHILD|WS_VISIBLE|BS_OWNERDRAW,
CRect(10,10,100,100), GetDc(), 1);
m_bitmap.LoadBitmap(IDB_PLAY,0,0,0);
This is not working

If you are in VC++ try with create the CBitmapButton in your resource editor, set the Bitmap there, and then when you make click on the button set the property to visible as you want.
If not...
With your code you are creating the bitmap and loading in the button but, are u sure that your GetDC () is pointing where you need?
Take a look step by step with the debugger

Simply start an unmanaged C++ project. Not a managed (CLR) one.
Use project type ATL, MFC or Win32.

You can get all the power of C++ and use MFC, qt, wxWidgets and WhatTheHeckElse as GUI Toolkit.
Windows forms are not possible - these are managed and require the installation of the .NET-Framework.
But you only need to install this once on a given PC. Like e.g. a Java VM.
Is this really a problem for you?
