      Hi, You trying to be too fast ;-) if ( x1.CompareNoCase( s1 ) || x1.CompareNoCase( s2 ) ) { ... }

              Hi, hm... interesting - and what type are x1 and mytext->contents -> is it CString too ? (I'm thinking about e.g. you use VS2005 where default is UNICODE defined and you try to compare default CString with char *) Besides you can check what exactly return particular comparing functions (if equal should returns NULL)

                you are using a logical OR operator, which returns TRUE if one of the 2 operands is TRUE. so if its 1st part (1st comparison) is TRUE, then the 2nd one is not executed... are you sure you want to use a OR ? don't you need a AND ( && ) instead ?

                            Loopname is a CString, right ? then look at the signature of CString::CompareNoCase(). it gets a PCXSTR parameter (so, pointer to char). so ther's no problem in doing so. if your code doesn't work, it is because of what i notified you previously. have you tried inverting the two statements in the OR operation (C-style string compared first) ?

                              What you've shown in now way indicates that contents is a pointer. While mytext is indeed a pointer, you've shown nothing of its contents member. If contents is indeed a pointer, what's it a pointer to?

                                if this does not work, split the CompareNoCase and the if in different statements and debug each statement separatly.

                                bool b1 = (x1.CompareNoCase(s1)== 0);
                                bool b2 = (x1.CompareNoCase(s2)== 0);
                                if ( b1 || b2 )
                                {
                                }

                                  What is this supposed to mean? If one of the calls to CompareNocase() is returning a non-zero value, which you have yet to verify, that indicates the strings do not match. Whether the strings match or not, your code is syntactically correct.

                                    Come on Satish ! You are still not reading answers well and replying to our queries well. 1. What does not working mean ? You need to be very clear. 2. Have you taken in to consideration when using || operator second operand will be looked only when first is false?

                                      Come on Satish ! You are still not reading answers well and replying to our queries well. 1. What does not working mean ? You need to be very clear. 2. Have you taken in to consideration when using || operator second operand will be looked only when first is false?

                                        if this does not work, split the CompareNoCase and the if in different statements and debug each statement separatly.

                                        bool b1 = (x1.CompareNoCase(s1)== 0);
                                        bool b2 = (x1.CompareNoCase(s2)== 0);
                                        if ( b1 || b2 )
                                        {
                                        }
