You can still use CFileDialog or GetOpenFileName(). It will just require a starting folder. Check out the OPENFILENAME.lpstrInitialDir member variable.

All IP-packets are sent with a CRC32 checksum that the receiver recalculates to validate the data. If the checksum is incorrect, the packet is discarded.
This happens regardless of what you do, it's how the IP-protocol works.
If you're using an UDP ports, the sender will never be informed whether the receiver got the packet or not, at any OSI level, since UDP traffic is connectionless.
If you're using TCP ports, the sender will be sent an ACK for each packet. Whether the packet is to be resent or not is depending on a configurable threshold in the registry found at HKEY_LOCAL_MACHINE/SYSTEM/currentcontrolset/services/tcpip/parameters.
This means that the sender cannot be informed if the receiver got a corrupt packet since the receiving application will never get the packet since it's been discarded.
I suggest you implement a small protocol of your own at the OSI application level that send ACKs to the sender's application. You will then be informed if the receiver never got the packet by the absence of an ACK.
Hope this helps

It's supposed to be hard, otherwise anybody could do it!

If you have it, it's most likely in the c:\windows\system32\ folder. Have you checked there?

Hi all,
As developing an NT service I've come across a little problem that I'm no able to sort it out. The problem is as follows:
My service is running on local system account (as it is natural) and one of its chores is to launch a particular process in a particular session and with the privileges of a particular user(impersonation). I think I do everything I am supposed to:
- Retrieve environment block of the user.
- Retrieve access token of the user we try to impersonate.
- Convert the token into a primary one.
- Stablish the session for the token.
- Fill in STARTUPINFO structure with the window station and desktop information
.
.
.
-Finally I call CreateProcessAsUserW this way:
CreateProcessAsUserW(hToken,
NULL,
wszCommand,
NULL,
NULL,FALSE,
NORMAL_PRIORITY_CLASS|CREATE_UNICODE_ENVIRONMENT,
Environment,
NULL,
&si,
&pi);
Well, the code I have in my service works perfectly well in any platform save for the case when I try to create a new process in a terminal session of windows 2003 Server (64 bits) where I get error code 6 (Handle not valid). Any suggestion? Thanks in advance.
Regards,
Alvaro

Hi,
I have a class which encapsulates a window. This class has all the Message handlers and stuff. Lets say this class is CMainFrame.
Now, I am creating CMainFrame from another class....
CMainFrame* cMainFrame = new CMainFrame() ;<br />
cMainFrame->CreateWindow() ;
Now when I destory the window does the object tha cMainFrame is pointing to also get deleted from memory or do we have to do it explicitly? What I did was
cMainFrame->DestroyWindow() ;<br />
delete cMainFrame ;<br />
cMainFrame = NULL ;
Is this destruction of the Window and object the correct way to do it?

From MSDN:
About DestroyWindow:
Destroys the Windows window attached to the CWnd object. The DestroyWindow member function sends appropriate messages to the window to deactivate it and remove the input focus. It also destroys the window’s menu, flushes the application queue, destroys outstanding timers, removes Clipboard ownership, and breaks the Clipboard-viewer chain if CWnd is at the top of the viewer chain. It sends WM_DESTROY and WM_NCDESTROY messages to the window. It does not destroy the CWnd object.
