Hello, everyone!
I want to write a process monitor whose function is, when a process is terminated, I can get the process ID of the terminated process and also the application name related with this terminated process.
Are there some materials or sample codes that I can make a reference? Is it a very hard work?
Thanks in advance,
Geo

Thanks, Jörgen buddy!
I can not open the link you provide. 
I have read some materials from MSDN on the topic OpenProcess and a sample program at
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/perfmon/base/taking_a_snapshot_and_viewing_processes.asp
But I think it can not meet my demand quite perfectly, because the sample code only takes a snapshot of the processes of the current time. And my purpose is, I can be notified immediately when a process is being killed. Maybe I need some hook on OS?
Can you help?
Best regards,
Geo

Sorry about that. I assumed you had the MSDN doc collection installed. :presumptious and embarrased:

Since you get a HANDLE from OpenProcess you can use wait functions on the handle. They're listed under Platform SDK: DLLs, Processes, and Threads: Wait functions (A bit more neutral reference ).
If you wait for a process, you wait for it to die if I'm not mistaken. I have done this before, although quite a while ago. I do not know where I have the code (probably not still around since I was just playing). But I know this is the way to go.

As you said, "I assumed you had the MSDN doc collection installed. :presumptious and embarrased", what topic or key words should I searched? Maybe I can find one MSDN doc collection from some others machine. Can I find them from Internet?
Can you help?

Can I use Wait Functions to wait for a process (or being notified when a process is being kill immediately)? I have read this document from the link and I find it can only be used on thread (not process) context.

Geo

I'm not sure in what transitions of a process will trigger the wait functions. Threads within that process may trigger them, exceptional errors, etc. But, you can always check the process status using the process functions when the wait function is triggered. You can check if the process is alive or not.
As for thread context, it applies only to the calling thread I believe. Anything with a HANDLE can be monitored with a wait function - may it be a thread, process, file, or what have you.

I will take some time looking the details of this topic. If you have got some sample codes which can meet my purpose, please share them to me.

In C++, names are mangled because of their polymorphic nature. Consider the functions
void func(int x) { ... }
void func(float x) { ... }. Clearly the name func is not enough as it is in C. C++ mangles the types involved into the name, resulting in "weird" names as the one you have discovered.
However, functions may be exported with C linkage. This means that you get an unmangled name of that function in the librarys symbol table. It also means that you cannot use that name any longer for polymorphic functions.
You should mark your function with an extern "C" clause. This MSDN link is a good starting point: ms-help://MS.MSDNQTR.2003FEB.1033/vclang/html/_pluslang_Linkage_to_Non.2d.C.2b2b_.Functions.htm[^]

I've got an ATL component that is used to get a Directory listing async for VB clients.
I have 3 interfaces in my Component.
IListing
IDirectory
IFileObject
I listing exposes a method of ExecuteImmediate, and Execute(it creates a thread to do the work).
It then uses the FindFirstFile/FindFirstFile etc to actually do the work.
In this area of the component, I create a CComObject<cdirectory> and store that in the member variable for my component.
Then the hard work is done, and each CComObject<fileobject> as added to the CDirectory object.
All this works perfectly. No leaks, etc.
I then call a property (Contents) to return the IDirectory which is my enumeration of the objects. Also fine.
If I add to the bottom of the ExecuteImmediate/Execute and Event to Fire_Complete(). The system crashes. I've gone through with the debugger, and I can't find anything.
I would really appreciate it if someone could identify any problems with this code(or if I should include some more).

Assuming you are not using free threaded apartments, you are in a canoe on a creek of manure, without paddles. You need to synchronize the apartments by marshalling the pListing interface pointer.
Take a look at Len Holgates excellent article which touches this subject: COM Mailslots - Designing asynchonous COM components for VB[^].

OK, Here is my message, I promise to make it quick!
I have downloaded the MultiThreaded server from http://www.codeproject.com/internet/winsockintro03.asp and I would like to know how I can replace "#Server Ready." with the persons IP.
Well, I added this code to the UINT ClientThread(LPVOID pParam):::
sockaddr_in from;
char temp[512];
sprintf(temp,"Your IP is %s\r\n",inet_ntoa(from.sin_addr));
send(client,temp,strlen(temp),0);
but it always replys back:
Your IP is 204.204.204.204
I use a loop back (127.0.0.1) so it should reply with this IP.
Have I done somethin rong?
If so pleaseeeee help me.
Thanks,
Tim![Rose | [Rose]](https://codeproject.global.ssl.fastly.net/script/Forums/Images/rose.gif)

Hi Tim,
the reason that the ip address is always 204.204.204.204 is that 'from' hasn't been initialised.
you'll need to call getsockname to fill in the ip address.
ie:
<br />
sockaddr_in from;<br />
char temp[512];<br />
<br />
<br />
int fromlen;<br />
fromlen = sizeof(from);<br />
getsockname ( client, &from, &fromlen );<br />
<br />
sprintf(temp,"Your IP is %s\r\n",inet_ntoa(from.sin_addr));<br />
send(client,temp,strlen(temp),0);<br />
Hope this helps,

Could you tell me how to present Chinese character '人' using TCHAR? and what's the relationship between TCHAR presentation of a internation character and its Unicode 0x????format?
Regards
World on the way

TCHAR is a macro. If the UNICODE symbol is defined, TCHAR is defined as wchar_t, and as char otherwise.
Your Chinese character '人' is a double byte character, so it must be represented using wchar_t, as follows:
wchar_t chinese_character = L'人';
I cut/pasted your character into a file and looked at it using a hex editor. The character in hex is 0x4EBA.

i want to make a program that runs at start up and keeps looking for, say MS word, n when its run it should add a menu in it
how???
|
|
|
|

One of the possible ways:
Using Spy find class of MS Word main window ("OpusApp"), and in your programm constantly check for new window of that class through EnumWindows and/or GetForegroundWindow and etc. As soon as new window of that class found -- you can modify it's menu...

I've got an edit box created with the ES_PASSWORD style and I need to toggle that based on a checkbox (similar to what WinZip does if you set a password on a zip file).
On XP it's behaving weird. GetPasswordChar returns 0x25CF, which is the Unicode code point for the default black dot (this is an ANSI app BTW). I can turn the password style off fine with SetPasswordChar(0). But when I go to turn the style back on, I call SetPasswordChar(0x25CF) and it doesn't work, the edit box behaves as if I passed 0xCF instead, which gives Ï instead of the dot.  Any ideas how to get this to work in an ANSI app?

Pinky, are you pondering what I'm pondering?
I think so Brain, but if we shaved our heads, we'd look like weasels!

You might try using SendMessage(EM_SETPASSWORDCHAR,...) directly. It's possible the ANSI-ness of your application is confusing things in SetPasswordChar.

Maybe you can just create 2 password input boxes: one with ES_PASSWORD style, another regular EDIT. You will show just one at a time.
