A combination of addresses like that often indicates a corrupt stack. However, based on your further comments, it's more likely an uninitialized variable. Have you been ignoring compiler warnings? > This error occurs at line when i m trying to invoke a > function. > in that function, there is used Class1.Create(self); > this Class1 is declared somewhere else as : > Class1 : Class of TEditor; > TEditor : Class(Tcomponent); It's much more helpful if you copy and paste your *real* code, instead of trying to remember what your code is and then typing it incorrectly into your e-mail program. I think Class1 is a valid variable declaration, but TEditor is not. Even though Class1 is valid, it's probably not what you meant to write. > and while looking inside this class, there is no where > written Constructor Create(......... > Is it b'coz of this missing Create(), i m getting > access violation? If a method really doesn't exist, then your program will not compile at all. Remember that a class *inherits* all the functionality of its ancerstor class, so methods declared in the base class are available to all descendant classes, too. > or is this b'coz of Class-reference that is not > getting it's refernce properly? Why are you working with class references at all? The probably probably is with the class reference not having a valid value. The obvious thing to check, then, is where the variable gets assigned a value. > please help me. i m very confussed and not even in > position to move ahead. > what should i do? > is there any alternative to this? We can't suggest alternatives unless you describe what it is you're trying to do and how you're trying to accomplish it. -- Rob ----------------------------------------------------- Home page: http://groups.yahoo.com/group/delphi-en/ To unsubscribe: [EMAIL PROTECTED] Yahoo!
