VC++ documentation tells, GetPrivateProfileSection is provided only for compatibility with 16-bit applications.
Can we use this function in VC++ .Net 2003?
Best Regards,

In the continue MSDN says that:"Applications should store initialization information in the registry."

Yes.
But you can alternatively use, as recommended, the registry.

Hi
I want to know, if some user is logged on the machine, this from a Win32 Service runing under LocalSystem Account...
Thk.

From MSDN:
Use WTSEnumerateSessions function to retrieve a list of sessions on a specified terminal server.
Or use WTSGetActiveConsoleSessionId function to retrieve the Terminal Services session currently attached to the physical console. The physical console is the monitor, keyboard, and mouse. Note that it is not necessary that Terminal Services be running for this function to succeed. Then use
WTSQueryUserToken function to obtain the primary access token of the logged-on user specified by the session ID. To call this function successfully, the calling application must be running within the context of the LocalSystem account and have the SE_TCB_NAME privilege. It is not necessary that Terminal Services be running for the function to succeed, but if Terminal Services is not running, the only valid session identifier is zero (0). Windows Vista and Windows Server "Longhorn" allow only services and processes started by services to run in session zero.
Caution WTSQueryUserToken is intended for highly trusted services. Service providers must use caution that they do not leak user tokens when calling this function. Service providers must close token handles after they have finished with them.

You might also want to see about RegisterServiceCtrlHandlerEx. The HandlerEx function is an application-defined callback function used with the RegisterServiceCtrlHandlerEx function. A service program can use it as the control handler function of a particular service. The control handler function is intended to receive notification and return within 2-3 seconds; it should start another thread to perform additional work.
It can receive notifications when a user has logged on and off: SERVICE_CONTROL_SESSIONCHANGE
If dwControl is SERVICE_CONTROL_SESSIONCHANGE, dwEventType can be one of the values specified in the wParam parameter of the WM_WTSSESSION_CHANGE message. All sorts of these parameters indicate if there was a log on or log off or other change to the session.
If dwEventType is SERVICE_CONTROL_SESSIONCHANGE, lpEventData is a WTSSESSION_NOTIFICATION structure.
Use this to determine which session to check.

Hi all,
Using my application I've found a file path anywhere on my machine and store the full path in a CString variable. That full path, like this,
"F:\\Files\\Read_File.txt"
What I want to do is, find the name of the file(without the extension), and then separate two words Read and File.
I have tried one thing. Use ReverseFind() method of CString class to find the last '\' sign. Then I used the Right() to get the required file name. I can use Right() easily because file name length is always fixed.
<br />
CString ss = "F:\\Files\\ReadFile.txt";<br />
CString aa;<br />
<br />
if(ss.ReverseFind('\\')== 8)<br />
{<br />
AfxMessageBox(ss.Right(12), MB_OK);<br />
aa = ss.Right(12);<br />
}<br />
<br />
if(aa.ReverseFind('.')==8)<br />
{<br />
AfxMessageBox(aa.Left(8), MB_OK);<br />
}<br />
In this way I can separate those two words as well.
Actually this code gives the file name, ReadFile.
But there is a real issue, on the first 'if' condition. First part of the path, that is "F:\\Files" is not fixed. So in the first 'if' condition number 8 can be change depend on the file selection on my PC. How can avoid that.
Thanks
I appreciate your help all the time...

ReverseFind gives you the location in the string of the certain character you are searching for. Using that it can already be flexible regardless of the length of the filename. To get the application name you can use:
aa = ss.Right(ss.GetLength() - (ss.ReverseFind('\\') + 1)); //add 1 to exclude the '\'
with some adjustments, almost the same procedure can be done to get the file name (without the extension)
aa.Left(aa.ReverseFind('.'));
For flexibility you can try to pass the result of ReverseFind to an int first to check if it returns -1 (character not found).

Ok, I've do it in this way.
<br />
CString ss = "F:\\SRF Resources\\SRF\\G00166_003_01.srf";<br />
<br />
CString aa, bb;<br />
<br />
aa = ss.Right(ss.GetLength() - (ss.ReverseFind('\\') + 1));
AfxMessageBox(aa, MB_OK);<br />
<br />
if(aa.ReverseFind('.') == 13)<br />
{<br />
bb = aa.Left(13);<br />
AfxMessageBox(bb, MB_OK);<br />
}<br />
What is your comments.
I appreciate your help all the time...

Even if you have a fixed filename length wouldn't it be better to just use:
<br />
if(aa.ReverseFind('.') != -1)<br />
{<br />
bb = aa.Left(aa.ReverseFind('.'));<br />
AfxMessageBox(bb);<br />
}
It is much more flexible if the filename was changed to another one.
Also, you can just use AfxMessageBox(bb); instead of AfxMessageBox(bb, MB_OK); since the default for AfxMessageBox is the one with OK button anyway.

Yep, it's better. At the same time I've try another way to do this, but felt so mess. Use Find() to get the last '\' and then read backward to find the name. Try to follow the same way to find '.' and avoid extension. Failed. :->

Thanks pal for the infor. I just used it, because I feel it is completed my code in view. Actually it is useless. I have to type more and more when I used message box. Actually on my testings I used more message boxes to verify my output. 
I appreciate your help all the time...

Hi,
for viewing intermediate results I seldom use MessageBox. I prefer either writing to
the console (which is the output pane in Visual Studio while debugging) as printf() does,
and/or writing to a log file. In both cases the advantages are: you don't have to click
OK buttons all the time, and you get to see a lot of intermediate results on consecutive
lines, seems easier to figure out where things start to go wrong.
Anyway, I tend to create a "void log(char*)" function that does the above (and appends
a newline if appropriate).

Thanks pal. Actually lots things I have done on MFC. So that's why I used that way to check weather I'm going wrong or not.

Why mess with all of this, where there are existing functions that do it for you? Will your code work with other character sets?

I have a mess here. I no it is complicated that this way.
CString::Find()
Thing is that, can I used index to get a sub-string. Basically it searches the sub-string which we define. Then gives ASSERT the application.
What is your comments on my thought.

Can you give the snippet of your code which causes the assert error?

Actually I don't have a code. I asked this based on MSDN example. I try it coding and let you know.

You mean the CString which I used. It's like this, a path of a file.
F:\Resources\Files\G00166_003_01.txt

Your code is inefficient, and makes many assumptions.

Check the PathStripPath() function
|
|
|
|

Thanks pal. But I feel that ReversFind() more easy, because I can use Mid() to extract any sub-string from the file name.
Thanks again.

I'd strongly recommend using the ShellAPI command that David pointed you to.
What about
c:file.txt?
or all sorts of strange notations for filenames you will hardly ever use, but the shell team have handled for you?
