Hi

Is it possible to change the mouse cursor? Something like

A_Cursor = Cross

(which doesn't work, I know

Any other way of doing it?

Thanks,

Ant.

It is possible using DllCall but I would suggest doing a bit of research first:
http://msdn.microsoft.com/library/defau ... cursor.asp

Sorry, I realize it's probably not the answer you were looking for... there are likely other methods... If I remember correctly, the registry path: "HKEY_CURRENT_USER\Control Panel\Cursors" should contain the paths to the current cursors in use if non-standard...

Hey corrupt,

Thanks for the info! Actually, its a great answer - I've been looking for an excuse to get into playing with DllCall for a while!

Will report back if I have any success,

Ant.

Ok, getting stuck already! This is how far I've got so far:

To discover what the (global) cursor currently is I can use:

Binding this to a key, I get different results for hcursor depending on the state of the cursor; this was my "calibration" test to check that I was using DllCall and structs ok. The info for the struct came from http://msdn.microsoft.com/library/en-us/winui/winui/windowsuserinterface/resources/cursors/cursorreference/cursorstructures/cursorinfo.asp?frame=true.

So far so good. Googling then told me that in order to change a cursor over a window, I need to replace its class cursor. The pseudo code for this is something like:

I've attempted to get this to work (changing the cursor to a Crosshair) as follows:


The GCL_HCURSOR value I found by googling; the IDC_CROSS value is MAKEINTRESOURCE(32515) - my value could easily be wrong for this

The tooltip tells me that the first call is failing; no error, but no pointer to a cursor resource either.

Any ideas? I'll keep playing around anyway. Thanks,

Ant

Hi Ant,

Any luck yet? I seem to remember that to load the cursor I had had to do something like:

Hey Corrupt,

Nope - no luck

I can't seem to get the line

to ever return me a value; result1 is always 0. No error is reported though. According to the MSDN doc, it should return me a handle to the new cursor. I'm wondering if my way of setting NULL is correct.

Any thoughts?

ant.

Ahh, ok, IDC_CROSS is a constant. I currently use APIViewer 2004 to find values to various constants, types, etc... and API Guide for a quick reference with various API calls .

According to APIViewer, IDC_CROSS = 32515

The following seems to work ok...

Ok! Now we're getting somewhere! I'm a bit busy with work today (it *always* gets in the way of the important stuff ), but have just tried this with some success:

WARNING: this will screw up your system cursors - its probably fixable, but I didn't have time this morning, so just rebooted to get them back to normal.


This will change the actual cursor rendered by the system; in this case it changes the cursor rendered when the system wants a standard, normal, arrow pointer to be the crosshairs. It only has effect outside of a (non-program manager) window; windows are responsible for setting their own cursors it seems, and this will be harder to alter (maybe not impossible though; although not recommended we can probably use the SetClassLong call to override a Window's class cursor). Another area to look at would be creating a full-screen, invisible window of our own and setting the default cursor on that to be what we want... Will experiment when I have some more time.

Thanks corrupt - can't believe I missed that... The value I had for IDC_CROSS was MAKEINTRESOURCE(32515) which I spent ages figuring out, and never bothered trying 32515 itself... d'oh.



Ant.

@ antonybI guess "Login as another user" will do it as well !?!

The following should fix the bug where the cross is kept after you close the script.
