GetSafeHwnd().
Don't get what you mean by your second sentence.
GetClientRect()/GetWindowRect().

It would be great if you organized your request in sentences.
What you wrote is really hard to understand.

But well...

To get a handle of a Dialog, you can use the method GetSafeHWnd(), or the member m_hWnd.
If you can't use that, you can try looking for your window through FindWindow()

What's the error you are getting? is it a compilation error?

CFileDialog

Hi all,

I need to open ascii files in a project and i do that like this;

CString str;
CFileDialog fd(TRUE, NULL, str, OFN_FILEMUSTEXIST | OFN_HIDEREADONLY);

if (fd.DoModal() == IDOK)
{
str = fd.GetPathName();
UpdateData(false);
[...]
}
I'd like to know:
1) how to modify the dialog caption (default is "Open File")
2) what's the meaning of UpdateData(False)
3) what should i do to save a file instead of loading it.

Thanx in advance,
Desmo16.

Chaning the text of the file dialog is simple.
try this code

CFileDialog dlg(true);<br />
dlg.m_pOFN->lpstrTitle = "Save as new title";<br />
dlg.DoModal();

You can use also GetOpenFileName and for save GetSaveFileName
see MSDN for UpdateData
In MSDN:

<code>
"CWnd::UpdateData
This method initializes data in a dialog box, or retrieves and validates dialog data."

How to get a Handle Type

4-Jul-06 3:32

Hi people

I belive I have seen a WIN32 funtion that you can use to know the type of a Handle.
I need to know if a handle references a file, a file map or another thing.

Does anybody knows how I can do that? I tried at msdn.com but I can't find anything

Thanks in advance Big Grin | :-D

I am not going to write any code for the same.
you just google for it.

steps.
1. Enumerate Windows (top level windows)
2. On enumeration, you will get handle of each window. decide, it's a top level window or not.
3. Call ShowWindow(hWnd,SW_MINIMIZE);

XML DOMDocument COM and windows service

I'm creating DOMDocument in the following way:
CoCreateInstance(CLSID_DOMDocument40, NULL, CLSCTX_ALL, IID_IXMLDOMDocument2, (LPVOID*)&m_pXmlDoc)
This works well when the code is compiled as usual console application. But when the code runs as windows service CoCreateInstance fails with E_OUTOFMEMORY error.
This only happens on some machines...

Thank you,

Rejecting connection from client

Using socket, how we could reject an incoming connection?

Re: Rejecting connection from client

If you have a server listening on a particular port, the OS will automatically 'accept' all connections coming in on that port. There's no way (using BSD sockets anyway) to reject a particular connection; all you can do is close the socket() once you've accept()ed it. What are you trying to achieve? If you want to allow connections from a particular address only, then you can accept(), check the peer adddress, then close() the socket if it's not the connection you wish to accept.

If you're just trying to allow one connection in, denying all others after a successful connection, then you can close the listening socket after accept()ing.

If you really need to give a 'connection refused' message to a subset of people, you should consider using a firewall instead.
