Max,

Num() converts integer to string, i.e. exactly the opposite of what the poster wanted...

Actually for situations like yours, you should be using Num.

Please check: http://www.symbian.com/developer/techlib/v9.1docs/doc_source/reference/reference-cpp/N101CA/TDes8Class.html#%3a%3aTDes8%3a%3aNum%28%29

TLex8...

Can you give me an example?

Try something like this:

Code:

TUint GetMyNumberL( const TDesC8& aStringAsNumber)
{
Â Â TLex8 lexer( aStringAsNumber);
Â Â TUint value;
Â Â User::LeaveIfError( lexer.Val( value, EDecimal));
Â Â return value;
}

void CheckMyImplementationL()
{
Â Â _LIT8( KAString, "1234abc");
Â Â TBuf8<42> buffer( KAString);
Â Â const TUint result = GetMyNumberL( buffer);
Â Â _LIT( KPanicCategory, "GetMyNumberL");
Â Â __ASSERT_ALWAYS( result == 1234, User::Panic( KPanicCategory, KErrGeneral));
}

I have a TBuf8 item and want to convert it to an integer (TUint) so I can count with it.

Any suggestions?

Try TLex8.
