There are a whole bunch of approaches you can take to this problem. The main question you want to answer, though, is how tightly coupled do you want the canvas and the window to be? Do you want to be able to use your AnaCanvas on any arbitrary window? Or do you have a more rigid layout in mind, where the window is going to always be the same?
If you want to use the AnaCanvas class in any arbitrary window, you should either give your canvas a StaticText property, that you set in the instance's Open event, or, even better, give the AnaCanvas a DisplayText event, that you can provide code for in the instance. RB windows do have a Control array and a ControlCount property that you can use to iterate through all the controls in the window, if you desire. You could look for a StaticText control with a particular name that way. If you want a more rigid layout, then you might want to subclass the window, so you can access it's controls more freely. Then you would cast the canvas' Window property to your subclass in order to access it's predefined controls.
