Hi,

My application involved multiple views, so I have to run the application using
return EikStart::RunApplication( NewApplication );

If I use iLog as below, I can only get the log file for Write functionality only.

GLDEF_C TInt E32Main()
{
__UHEAP_MARK;

RFileLogger iLog; //TODO: include all these in macros, and check return codes

iLog.Connect();
iLog.CreateLog(KTag1,KTag2,EFileLoggingModeOverwrite);
iLog.Write(KTestString);
iLog.CloseLog();
iLog.Close();

__UHEAP_MARKEND;

return EikStart::RunApplication( NewApplication );
}

How can I take the log file for an entire application.

Do I need to write those 5 lines in every function?
It will be complex...right ?
Whats the correct procedure ?
Can anybody help me out....

I found the way: RFileLogger works exactly as before. All you need is being able to explore folder C:\logs. A first freeware file explorer is available to S60 3rd: http://simonjudge.com/symbianseries603rdfreeware.html through it, I copy my log file to E: or C:\Data and I can see it on my PC's phone browser.

I can see that class RFileLogger is still there in S60 3rd. The problem is the implicit path where static methods used to write (c:\logs) which is not any more available to applications, or at least it is not browsable via any file explorer. I tried using the class as I did in S60 2nd and no problems arise except that no file is available. Is the implicit path still the same or is it changed? Any workaround to use RFileLogger's static methods in S60 3rd? Thanks in advance,

Put the declaration of "RFileLogger iLog;" in the .h file will be better.

Try to delete the LogFile after CloseLog.... impossible:) I can't create a kind of rolling logfile.

Hi.

I tryed to use RFileLogger.

The application compile well for WINS, but when I try to compile for thum I got the following error:

-f "\Symbian\8.0a\S60_2nd_FP2\EPOC32\BUILD\MISDOCUMENTOS\DESARROLLOS\SYMBIAN\AUDIODAEMON\GROUP\THUMB.make" TARGET CFG=UREL VERBOSE=-s make[1]: *** No rule to make target `\SYMBIAN\8.0A\S60_2ND_FP2\EPOC32\INCLUDE\FLOGGER.H \SYMBIAN\8.0A\S60_2ND_FP2\EPOC32\INCLUDE\FLOGGER.INL', needed by `..\..\..\..\..\SYMBIAN\8.0A\S60_2ND_FP2\EPOC32\BUILD\MISDOCUMENTOS\DESARROLLOS\SYMBIAN\AUDIODAEMON\GROUP\AUDIODAEMON\THUMB\UREL\AUDIODAEMON.o'. Stop. make: *** [TARGETAUDIODAEMON] Error 2

Some body know what's happening?. RFileLogger must be used only in wins.

Thanks.

Hi TQ

I'm not sure if you still have the problem of creating the folder c:\logs\myfolder\ automatically. You're right the directory HAS to be there. You can do this either with an RFs::MkDirAll or RFs::MkDir in your app (see SDK help: "API Reference Â» File Server Client Side Â» RFs"), or if you don't have to create the directory from within your app you can use a file manager, such as the built-in ones that come with your phone.

You can use RFs::SetAtt (same SDK help page as before) to set attributes.

one of the lines in your code:

iLog.connect();

Could there have been an error because u're using small "c" instead of capital "C"? Try

iLog.Connect();

instead

btw, i'm trying to create the folder

c:\logs\myfolder\

automatically but with no success. Can anyone help? This is important because without the correct path, the logger wouldn't log. also, can someone tell me how to set the file to "Read Only" and back to writable mode?

hi i have done all the steps as mentioned, but i am not able to use the write function outside constructl(). it gives a compilation error ("Write' : 4 overloads have no legal conversion for 'this' pointer").

here is what i have done

in .h RFileLogger iLog;

in .cpp //in constructl ()

iLog.connect(); iLog.CreateLog(KLogDir,KLogFile,EFileLoggingModeOverwrite); iLog.Write(_L("inside constructl"));

//in some func foobar() of same class

iLog.Write(_L("inside foobar")); //this line gives the error.

What about creating a log file on the MMC of the device ? Is that possible ?

I tried using iLog.HexDump() and I can't get it to compile! Can you explain the parameters in: iLog.HexDump(aHeader,aHeader,myPtr,4) ? What is the type declaration for aHeader and how do I initialize it, what is the type declaration for myPtr, what does the 4 do? How does this function work?

The error code needs to be checked for the Connect and CreateLog since CloseLog will panic if the connection does not exist. But, the general log functions will silently fail if the connection failed so these do not need Â“ifÂ” statements before them.

I tried out your code and it works. The code I compiled was:

#include <flogger.h> _LIT(KTag1,"Mobeel"); _LIT(KTag2,"GPRS.txt"); _LIT(KTestString,"1111111111111111111111111111111111111111"); GLDEF_C TInt E32Main() { __UHEAP_MARK; RFileLogger iLog; //TODO: include all these in macros, and check return codes iLog.Connect(); iLog.CreateLog(KTag1,KTag2,EFileLoggingModeOverwrite); iLog.Write(KTestString); iLog.CloseLog(); iLog.Close(); __UHEAP_MARKEND; return KErrNone; }

and I created this directory:
S:\epoc32\wins\c\logs\Mobeel
to see the GPRS.txt file

Need to debug some code on a mobile or track the execution flow ? The RFileLogger class is really useful to create log files...
