Bite #1 / 3	Beginner Questions where everybody knows the answer :) Hello to all... I have these two problems... 1. I can't declare constant below:- const double DX = 0.003; inside a header file, in public section of CDialog, saying ' illegal pure syntax, must be '= 0' ' when compiled. What didi I do wrong? 2. I know how to draw on the dialog, but how do I draw inside a picture control on the dialog window? And also, can I set the drawing area to scale, say -1 at the bottom up to 1 on top, as we can do in VB? Thanks... -- [ICQ# 54972548 ] =========================

Joe Delekt #2 / 3	Beginner Questions where everybody knows the answer :) Greets, This is a known issue with initializing (static) members in the class declaration. One needs to declare and initialize your variable as such: class CMyClass { public: static const double DX; Quote: }; const double CMyClass::DX=0.003; Regards, Joe Quote: > Hello to all...

I think you need to make it static. Or declare it outside the class. Quote: > 2. I know how to draw on the dialog, but how do I draw inside a picture > control on the dialog window?
