Hi All,
I am facing an issue relating to named pipes.
The OS used is Vista.
I am creating a named pipe within a service that is running in session zero. A client application tries to read through the pipe by calling api CreateFile. This fails since the client application is running in the user context.
Is there any way that this caould be overcome? Should i pass any securtiy attributes to the "CreateNamedPipe" or "CreateFile" apis?
Thanks in advance 
Sunil

I want to send a key to a window. I used Global Hook and my code is like this :
//In hook proc :
if(nCode <0)
CallNextHookEx(MyHook,nCode,wParam,lParam);
hWndApp = CWnd::FindWindow(0,_T("Test"));
if (hWndApp == NULL)
MessageBox(NULL,L" Can't find the window", L"",0);
hWndApp->SendMessage(WM_CHAR, 8, 0); //Backspace
It can find the window but it can't send the message. Some one plz help me ![Rose | [Rose]](https://codeproject.freetls.fastly.net/script/Forums/Images/rose.gif)

I think you should should send:
WM_KEYDOWN
WM_CHAR
WM_KEYUP

If the target window is active, you can use SendInput().

I've read many pages from the pages you gave me but I still can't find the answer They recommend to use SendMessage but it doesn't work with SendMessage...

Is the problem with sending or receiving? What does your code look like?

This is my code :
HWND windowHandle = ::FindWindow(0, _T("Test"));
INPUT *key;
::SetForegroundWindow(windowHandle);
key = new INPUT;
key->type = INPUT_KEYBOARD;
key->ki.wVk = VK_CONTROL;
key->ki.dwFlags = 0;
key->ki.time = 0;
key->ki.wScan = 0;
key->ki.dwExtraInfo = 0;
SendInput(1,key,sizeof(INPUT));
key->ki.dwExtraInfo = KEYEVENTF_KEYUP;
SendInput(1,key,sizeof(INPUT));
::SendMessage(windowHandle,WM_KEYUP,0,0);

What does SendMessage() return?

You must first create your font with CreateFont and then use of SetFont.
