Is there a use for enumerating registered windows messages?

I need to write a web query in C++ to obtain a stock price. The code will be used in an Excel Add-In. I can do this easily in VB using: QueryTables.Add( ... ), but cannot find a reference to a C++ implementation.
Any help appreciated.
Regards.

I have created a new dialog-based Project using MFC. Then I added a few other .cpp-files from older projects to this new Project.
But now I have the problem that member variables from the files created by MFC are not avaiable in the old files i added myself, although I included all avaiable headers in these files.
When I try to use them, the error "C2065: 'm_member' not declared" occurs.
All Files (both old and new) have headers like this:
#include "stdafx.h"
#include "ApplicationName.h"
#include "ApplicationNameDlg.h"
#include "DlgProxy.h"
Thank you for your help,
Ronin.

Thanks! I'll take a look at gethostbyname()...

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'....

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?
-Ian

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!
