i tried your code, it works very ok, it wrote the value 100, stored inside numIndex

what value does this code returns in your case?

Code looks fine to me. Not working means what happens?? what is final value of numIndex ???

Try again properly Arun. As other guys are saying that its working.

my problem are given below

Tint num=100
LogPrintfL(KLogFile,"num %d ",num);

the value of num ie 100 are successfully writting a File

then

_LIT(mn,"100");
TBuf<100> at;
at.Copy(mn);
 TInt numIndex;
 TLex iLex(at);
 iLex.Val(numIndex);
LogPrintfL(KLogFile,"num %d ",numIndex);

by using the above code the value written in file is not same as actual value
i m getting below value in file

num -2045913644

ok try one thing, do not write this value in a file just show it in a popup or some alert, then see what vakue it is showing up.For e.g:

TBuf<20>buffer;
buffer.AppendNum(numIndex);
CAknInformationNote*note = new(ELeave)CAknInformationNote;
note->ExecuteLD(buffer);

so now see what value it pop ups

ok thanks

now my problem is

_LIT(mn,"9999999999");
			TBuf<256> at;
			at.Copy(mn);
			  TInt numIndex;
			   	 TLex iLex(at);
			   	 iLex.Val(numIndex);
			   TInt ar;
			   ar=numIndex;
			  // TInt64 ac(ar);
			   	LogPrintfL(KLogFile,"number %d ",  ar);

the bove value not write the file
but
the given value are ie 1234567891 are successfilly written

_LIT(mn,"1234567891");
			TBuf<256> at;
			at.Copy(mn);
			  TInt numIndex;
			   	 TLex iLex(at);
			   	 iLex.Val(numIndex);
			   TInt ar;
			   ar=numIndex;
			  // TInt64 ac(ar);
			   	LogPrintfL(KLogFile,"number %d ",  ar);

Check if 9 999 999 999 happens to be larger than 2 147 483 647 (the largest number which can be represented by a 32-bit signed integer). Then repeat the same check with 1 234 567 891.
