I'm experimenting the usage of bitmaps. I started by downloading an example project from codeproject and I'm trying to modify it: http://www.codeproject.com/miscctrl/oscope.asp I would like the oscilloscope to plot the points starting from the left side of the screen, ending at the right side. At the moment, the bitmap points are plotted from right to left (I would like it to be the opposite). I already added a multiple graphs' support to the program, but can't solve this simple direction problem. Can someone give me a hint on how to fix the situation, please?

I don't know how to refer to a certain (open) modeless dialog from my program's MainFrame, where I create them. I would like to implement reference to a modeless dialog by checking the dialog's caption and then specifying whether or not the message was supposed to be sent to that dialog. This raises a question: Is there a useful function that I could use to check all open dialogs (and their captions)? If there isn't such a function, is there another way of knowing which (modeless) dialog is supposed to receive the message? I don't have to communicate between my program's various modeless dialogs, just send data to them.

If I create several modeless dialogs, how do I keep track of what happens in each one of them? I couldn't find much information on this subject, so I'd really appreciate any help! Does anyone know some good links or samples on modeless dialogs? Thanks in advance!
