Simulate Mouse Click using SendInput Win API call

[ronniepo]

Has anyone had any luck simulating a left mouse click using
the SendInput Win32 API function?

I've seen numerous examples on how to use the older
Mouse_Event() function, but this doesn't seem to work
(crashes) in Windows XP.

What does your code look like?

That msdn topic is what inspired me to issue a call for help
here. As a non-VB programmer, I wasn't quite sure how to
translate the parameter types when declaring the global
external function for SendInput().

For what it's worth, my implementation of Mouse_Event(),
which crashes with a "Bad runtime function" message in
Windows XP, looks like this:

/* Declare Global External Functions. */
FUNCTION boolean SetCursorPos(int cx, int cy) LIBRARY
"User32.dll"

SUBROUTINE Mouse_Event(ulong dwflag,ulong dx,ulong dy,ulong
cbutton,ulong dwextra) LIBRARY "User32.dll"

//dwflag: 1 = do nothing, 7 = L-button clicked, 25 =
R-button clicked

/* Position cursor and simulate mouse click */
integer li_x, li_y

/* After successfully setting li_x and li_y to the desired
pixel coordinates: */

SetCursorPos(li_x, li_y) // This part works

Mouse_Event(7, 0, 0, 0, 0) // "Bad runtime function
reference..."

Hi Ronnie;

Why not just use the built-in PB SEND method?

For example ... LHMB on an SLE within a window:

Send(Handle(wm_mywin), 273, 0, Handle(sle_1))

I'm looking at http://msdn.microsoft.com/en-us/library/ms646260.aspx and it
shows the function name as mouse_event with lower case. That may be why it
is not found, see the first gotcha on http://www.sybase.com/detail?id=44648

Wow. That solved it. It didn't even occur to me to consider
the case.

Thanks for pointing that out, Jerry.
