You can define your own message and like WM_SYNC_MYTEXT and send it to the specified control window. that message has to be handled at the tree control side (i.e derive your own tree control from CTreeCtrl) and handle message inside ON_MESSAGE macro inside the message map)
Please check MSDN

There may be a better solution for your problem. What I've said is a quick solution.

What exactly does this mean?

Ok, so what's the problem? If you have obtained the string from the list control (into a variable of some sort), the list control is no longer part of the problem.

So are you deleting it from the list control?

So are you adding a NULL item, or changing an existing item to NULL?

Assuming you are using MFC, you've likely got something like:
int nIndex = m_list.GetNextItem(-1, LVNI_SELECTED);
CString strItem = m_list.GetItemText(nIndex, 0); Now until you assign another value to strItem, it will retain its value indefinitely. Interacting with a tree control has nothing to do with it.

This makes no sense. What are you trying to say?

i was trying to get white color in my application.
my background is grey. when i try to bitblt my dc with paint dc in onpaint i am using SRCPAINT.
so white color is becoming grey.

if you want the background color of your application to white handle WM_ERASEBKGND and Fill with white color,
CWnd::OnEraseBkgnd(CDC *pDC)
{
pDC->PatBlt(..., WHITENESS) or pDC->FillRect()
}

Hi All,
I am developing an application in which I need to connect to a server and send some commands and retrieve the response. For this, I am using a third party console client application called Plink. Plink requires a console window to start and it cannot be opened by double clicking it. The entire process of login and sending commands and receiving response is automated in my application. Also plink has to be started with a initial command "plink <protocol> <server ip="">".
Code flow:
------------
m_Stdout = GetStdHandle(STD_OUTPUT_HANDLE);
m_StdIn = GetStdHandle(STD_INPUT_HANDLE);
SecureZeroMemory(&m_ProcInfo,sizeof(PROCESS_INFORMATION));
SecureZeroMemory(&m_StartInfo,sizeof(STARTUPINFO));
// Set up members of the STARTUPINFO structure.
m_StartInfo.cb = sizeof(STARTUPINFO);
m_StartInfo.hStdError = m_Stdout;
m_StartInfo.hStdOutput = m_Stdout;
m_StartInfo.hStdInput = m_StdIn;
m_StartInfo.dwFlags = STARTF_USESTDHANDLES;
// Create the child process.
wcscpy(m_Cmdline,_T("plink -telnet <server ip="">")); // server IP is not typed here for security purpose
m_RetVal = CreateProcess(0,
m_Cmdline, // command line
NULL, // process security attributes
NULL, // primary thread security attributes
TRUE, // handles are inherited
0, // creation flags
NULL, // use parent's environment
NULL, // use parent's current directory
&m_StartInfo, // STARTUPINFO pointer
&m_ProcInfo); // receives PROCESS_INFORMATION
memset(m_UserName,0,BUFSIZE);
wcscpy(m_UserName,_T("pdt2"));
wcscat(m_UserName,_T("\r\n"));
m_BytesToWrite = wcslen(m_UserName);
m_RetVal = WriteConsole(m_Stdout,m_UserName,m_BytesToWrite,&dwWritten,NULL);
if(m_RetVal)
{
fprintf(m_FilePtr,"Write to console succeeded\n");
ReadFromConsole();
}
else
{
m_ErrorCode = WSAGetLastError();
ErrorExit("Write To Console failed",m_ErrorCode);
}
-------------
This is where it fails. After writing the username string to the console, I should get back the password prompt in the console window which doesnt happen.The WriteConsole API succeeds and returns 1 but the application doesnt get back the password prompt as should be the case.In WriteConsole API I pass the standard output handle m_Stdout.
Can anyone say whats going wrong?
Thanks in advance for any kind of help.

Console expects "\n" as newline character rather then "\r\n".

Hi Saurabh,
Thanks for replying.
I even tried with "\n" only but that too is not working.I suspect that WriteConsole is writing to the standard output but console is not able to send the username string to the server. Or may be we need to send the username to Plink somehow so that it sends the username to the server.
Thanks,
Jyoti

What is the value of dwWritten after this call?

Do you see it being written, or are you just assuming?
