    Few ways to do it.....here's a few

    Code:
    	TCHAR *buff = "Hello World";
    	MessageBox(buff);
    
    	CString str;
    	str = buff;
    	MessageBox(str);
    
    	TCHAR *buff2 = new TCHAR[str.GetLength()+1];
    	if(buff){
    		_tcscpy(buff2,str);
    		MessageBox(buff2);
    	}
    Dont forget that CString's operator=() will take normal char strings for assignment...

    And its operator LPCTSTR() allows you to use string copy functions
