Every time I click and hold down a button Control (a "real click") on an app, the button stays depressed, and window spy shows a WM_LBUTTONDOWN message (0x201,1,0x00190019) [==>Lbutton down, at coords 25,25).

When I release the left mouse button, the window sends the WM_LBUTTONUP message, as it should.

However, when I try to post the exact same WM_LBUTTONDOWN message with the same parameters, via postmessage or sendmessage, Windowspy show that a WM_LBUTTONUP message is immedialy sent to the window, even thought I never implicityly send it!

Code:

F2::
WM_LBUTTONDOWN = 0x201
PostMessage, WM_LBUTTONDOWN, 1,0x00140019, Button4, ahk_id %winID%
Return


I have the same results even when I use ControlClick with the "D" option. Ive tried the NA option as well as SetDelay,-1 to no avail also.


Ugh... very frustrating. Any way to "trick" it or is there another WM_HOLDDOWNTHEFRICKINGLBUTTON command I'm not aware of?


Any help is greatly appreciated....

Thx!

After much trial (with lots of error), I'm wondering why
Code:
Click, Down
would work, but not

Code:
PostMessage, WM_LBUTTONDOWN, 1,0x00140019, Button4, ahk_id %winID%


I'm guessing it has to do with the "physical" location of the mouse. As soon as my PostMessage is executed, the system realizes that the "real" mouse is not where it thinks it is, so it immediately "grabs" the mouse where ever else it is on the screen (which is NOT over the button I'm activating) and hence a "WM_LBUTTONUP" message is generated.

Is there any way to temporarily diable the mouse, so the system thinks it's still pressing the button down as a result of the last WM_LBUTTONDOWN message?

Many thanks!

I confirmed that if I first move the mouse to the control, then send a WM_LBUTTONDOWN message, that it works! Laughing

Unfortunatley, I don't want to have this window visible to the user. Is there any way to trick the system into thinking the mouse is somewhere other than where it is?

I'm about to checkout nomousey...

This is not something that the system does. To demonstrate:
Code:
Gui, Add, Button, W100 gonclick
Gui, Show
Gui, +LastFound
Sleep, 1000
ControlClick, Button1,,,,, D  ; WM_LBUTTONDOWN
Sleep, 1000
ControlClick, Button1,,,,, U  ; WM_LBUTTONUP
return

onclick:
    MsgBox click
    ExitApp
return
Perhaps the target application is behind it. Also note ControlClick works by posting mouse messages.

Doesn't seem like there is a solution, but hopefully someone will prove me wrong. Very Happy
