Hi,
I just tried this
CString s = "First line\r\n";
CFile file("c:\\test.txt", CFile::modeCreate | CFile::modeWrite);
file.Write(s, s.GetLength());
s = "second line";
file.Write(s, s.GetLength());
and this is what I see in the text.txt file
First line<br />
second line
Do you see something I did differently?

yes, you're writing one line at a time, whereas I was writing the whole string at once. But since I wanted to keep the previous contents of the file, I specified CFile::modeNoTruncate as one of the flags, but whatever I write is still appended to the end of the line that was previously there.
If it's broken, I probably did it

The seek to end may be truncating the \r\n on the final line.
Try adding a \r\n pair to the beginning of your string.

Hi,
How about this?
CString s = "\r\none more line";
CFile file("c:\\test.txt", CFile::modeCreate | CFile::modeWrite | CFile::modeNoTruncate);
file.SeekToEnd();
file.Write(s, s.GetLength());

text has the 'r\n\'
I hope this is a typo and you actually have '\r\n'....

YES, that was a typo; I actually did have the right text down, even though I've made stupider mistakes before!!;)

I need to shut down explorer.exe programmatically. I think I can use PostThreadMessage but how do I retrieve the process ID for explorer.exe?

easy. have a look at msdn, topic "OpenProcess". there you will find the link "Taking a Snapshot and Viewing Processes" with an example of how to list all processes. execute this code, check if the exe file name is "explorer.exe" and so you will get all instances of the explorer. open it with OpenProcess and then close it by TerminateProcess.
Don't try it, just do it!

From MSDN:
The TerminateProcess function is used to unconditionally cause a process to exit. Use it only in extreme circumstances. The state of global data maintained by dynamic-link libraries (DLLs) may be compromised if TerminateProcess is used rather than ExitProcess.
MSDN suggests you should use ExitProcess instead of TerminateProcess...

ExitProcess() only exits the current process. To force another process to close, you have no choice but TerminateProcess().

how do I find out the current path that my executable is executing in? Thanks

No, this is wrong. This will get the path the executable is currently "working" in. Might be as well C:\Windows or any other directory.
What you want is GetModulePath.

thanks!!! the other solution gave me the last path that the user browsed to with my 'File Open' dialog.

using simple sockets how can you test if the connection has been broken by the other server?
|
|
|
|
|
try to receive data and if it fails check call WSAGetLastError and then you will see if the connection was closed.
Don't try it, just do it!

Hey all,

Is the DLL being loaded an MFC extenbsion DLL? If so, are AfxInitExtensionModule() and AfxTermExtensionModule() being used?

Have you set a breakpoint on line 85 of appcore.cpp to see why the assertion is firing?

Debug -vs- Release?
Make sure the dll and the executable are compiled for the same type.

First some details:
Our application receives a data feed over a fiber optic T1. We develop both the client and server applications that send and receive the data. Both applications are written in ANSII C++ for portability. We use Winsock when running on a Windows platform.
The problem:
Sometimes the T1 line experiences 25% loss according to the ping tool. During these times we often see our connection from client to server disconnect with an error 10054 (An existing connection was forcibly closed by the remote host.). Is there anything we can do, programatically, to avoid connection loss or to quickly recover from the connection loss?
Thanks in advance
