Hi, 

my name is Kray and I am new to these forums and to AutoIt programming.

 

I'm trying to understand utilize the above user provided function that I found through Google.

I understand and get the gist of what its supposed to do, but what do the  0x001 numbers on the Local variables mean? Also this function came with the end function of MakeLong. Is that to simulate mouse dragging?

Finally, how do you call this function?

I used the help file as a reference and called the func before I included it at the bottom like so:

AutoItSetOption("MouseCoordMode", 2)
Call ( "_MouseClickPlus" ["homefrs-iphone.local - TightVNC Viewer"], ["left"], ["198" & "236"], [1]))

 

That didn't work so I tried calling it this way:

Call ( "_MouseClickPlus" [$Window = "homefrs-iphone.local - TightVNC Viewer"], [$Button = "left"], [$X = "198" & $Y = "236"]))

Still didn't work. Any help would be greatly appreciated.

I looked in the FAQs and did not see anything pertaining to this.

Hi Kray - Welcome to AutoIT.

but what do the 0x001 numbers on the Local variables mean

 

This just assigns a value to a variable

came with the end function of MakeLong. Is that to simulate mouse dragging?

 

No, this is used to format values for parameters to DLLCALL's for "SendMessage".

Finally, how do you call this function?

 

Like "_MouseClickPlus('my window')"

Also, read the header of the function.  It says that you must use "MouseCoordMode" 0

edit: example of calling a function

; *** Start added by AutoIt3Wrapper ***
#include <GUIConstantsEx.au3>
; *** End added by AutoIt3Wrapper ***

#AutoIt3Wrapper_Add_Constants=n

local $gui010   =   guicreate('test',200,100)
local $btn010   =   guictrlcreatebutton('Click Me!!',50,50,100,20)
                    guisetstate()

while 1
    switch guigetmsg()
        case $gui_event_close
            Exit
        case $btn010
            _MyFunction()
    EndSwitch
WEnd


func _MyFunction()
    ConsoleWrite('I just got called' & @LF)
endfunc

Thank you for the warm welcome.

I get an error on Line 25 that says:

 

Call"_MouseClickPlus('TightVNC Viewer'),'left','198','236','1')"
^ERROR

Error: Error parsing function call.

I got it to work, but not really. Edited August 21, 2013 by Kray

Try this

Call( _MouseClickPlus('TightVNC Viewer','left','198','236','1'))

or this

_MouseClickPlus('TightVNC Viewer','left','198','236','1')

[Kray]

I got it. However, the function does not work.
I can't understand why.
I'm looking at different threads to see if I can find more information.

I changed the MouseCoordMode to 0 and it still doesn't work.

Kray,

Perhaps you should find another way to do this.  See >this post.

I have the Control Handle.

Can I send a click by that?

If so how?

Start reading the Help file. Particularly "controlclick"...

Thank you  all for your help.

I will take your advice and read the help file.
