I'm logging errors to a text file, and the text has the 'r\n\' escape characters in there, but it still keeps writing to one continuous line. How do I stop this?

If it's broken, I probably did it

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());

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

How to shut down explorer.exe?

2-Jun-04 2:58

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! Wink | ;-)

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().

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.
