Hi,
I've been using your bitmap zooming code referenced here http://forums.ni.com/ni/board/message?board.id=231&message.id=3019#M3019 (it's a life saver).
I have one question though.. I'm trying to change it so I select an area of interest using cursors (and not Zoom Rect YX) ... when i hardcode the call to StretchBlt to always zoom to a predefined offset, width, and length, it works... but when i add a button to the program to call ScalePlotArea (where the StretchBlt call is hardcoded and all the calculation lines are removed) the plot area is not refreshed.
it seems like the bitmap is actually updated, but not refreshed to screen, because when i hold the mouse down and drag over a region of the plot, the zoomed image is refreshed, below.
i hope that made sense. is there a way to add cursors to your project for zooming instead of using Zoom Rect XY? i'm very interested in expanding it like this.
thank you,
Ryan
