Re: Mouse XY coordinates are changing slightly when Left MouseButton is pressed

Thanks Mark for you help.

I know that 1 pixel thumb-nail sounds extreme and I will try to make it up

but is used in a timeline control where 1 pixel corresponds to 1 second and a slice

might have only 1 second duration which as I already said coresponds to 1 pixel width.

Anyway, you suggest that I should ingore the XY coordinates I get from the WM_MOUSEMOVE

and check all over the time the GetCursorPos either on MouseMove or LButtonDown events? Is that a slow method?

I did not find anything related to this in the MSDN. I suppose you have right, but I can not understand why the XY-coords

are given from the above events, if they are unreliable.

Best Regards,
George

They're reliable but they reflect the cursor position at the
time the message is created and dispatched. Since there's no
WM_MOUSESTOP message, it's not always possible to get the actual
current cursor position from the last received WM_MOUSEMOVE
message.

I personally use GetCursorPos() in all my mouse message handlers.
The mouse is a relatively slow device, so the time it takes to
call GetCursorPos() is insignificant.

if you don't want to use a STATIC control then you have to handle the WM_PAINT message and write the text (possibly using TextOut) in your message handler.
