you can define a function CString getfirstparam(CString& strParam) { CString str,str1; int i; i = strParam.find(','); str = strParam.left(i); str1= strParam.right(strParam.Getlength()-i-1); strParam =- str1; return str; }

All know that the vc has some Predefined Macros,such as __LINE__ ,__FILE__ etc.when the programmer write the code __FILE__ in the file myclass.cpp ,the compiler will convert it to "myclass.cpp". Now i want to create a macros __CLASS__,so when programmer write the code __CLASS__ in a class (such as CMyClass )function ,the compile will convert it to the class Name ("CMyClass"),can i realize that ?if can ,how? CMyClass { void DisplayMyName(); } void CMyClass::DisPlayMyName() { AfxMessageBox(__CLASS__);//When Compile it will be converted to AfxMessageBox("CMyClass") } thanks
