Full Screen X-hair Cursor

[TonySteer]

I am working on a dual monitor system with the left monitor diplaying a window with several child windows. I need to implement a full screen cross hair cursor for this display, reverting to the normal windows cursor for the right hand display. It is important that mouse messages are processed normally when the cursor x-intersection is on each child window. Anyone any ideas how this might be achieved?
Thank-you

You want hair cursor which will be visible only inside of the client area of current child window, right?
How to do it:
1. You must hide original Windows cursor. You overwrite OnSetCursor of your view and set cursot to NULL.
2. You must be able to draw cursor manually. You must redraw cursor on in new position in OnSetCursor



Good luck

If anyone has sample code for doing this, I would really appreciate it. I have to do the same thing.

Thanks in advance,

I need to make a full screen cross-hair cursor, and the cross of the cross-hair needs to follow be the hotspot of the cursor. I hope that makes sense. Any help, or sample code for doing this would be great.

Thanks in advance,

Wade

When you say 'full screen' you don't really mean 'full screen', do you? You don't mean that cursor must be drawn on window's non-client area (like toobars, caption, scroll bars etc) and outside of the window? You want cross-hair cursor to be drawn only in a window's client area, is it correct?

Sorry, yes you are correct. A co-worker busted me for saying the same thing to him. Sorry for the misunderstanding, I only want the cross-hair in the window's client-area.

Thanks,

It's relatevely easy to do. Are you sure there are no samples on CodeGuru? Try to find the sampel on CodeGuru, if you are sure there are no such a sample, I will make one for you

I can't seem to find an example anywhere. I've searched MSDN, CodeProject and CodeGuru. I don't know maybe I'm not searching for the right words, but I can't find it. If you have some sample code handy, I would greatly appreciate it.

Thanks in advance,

Hello
I made a sample for you. Where do you want me to send it?

It's a very basic sample, I overload only OnSetCursor. More complex situations will require more complex code. Anyway it's a good sample to start with. Feel free to ask if you don't understand anything in a code.
