sneding keystroke(not mouseclick) to inactive window

12 posts in this topic

Hi all,

New AutoIt user here, and I have to say I have been missing out. Of course no one posts just to say everything is fine, so now down to business.

I am attempting to send a series of keystrokes to a inactive window, which I do not wish to gain focus on. I have the WinHandle for the window in question, and if I use ControlFocus it works just fine. Doing some digging everyone seems to refer people with this problem to Insolence's UDF here: http://www.autoitscript.com/forum/index.ph...c=7112&st=0.

This is great, it is what I want to do, EXCEPT it is mouse clicks and not keystrokes. I am not a windows programmer so I am not familiar with user32.dll and how I would need to modify this code to send "F1" for instance, instead of a mouse click.

Can anyone help?

To send a keystroke to a specific window, I believe you can use ControlSend, but I don't know if the window will stay inactive when you do that.

To send a key like F1, put it in curvy brackets like so: {F1}

Yes ControlSend will send the key fine, once the window has focus. I am trying to send to a minimized window which I do not wish to gain focus at all.

I just had a bit of luck with google, and found some messages that indicate it should be possible using a dllcall, now if I could figure out the exact syntax I would be in business. See below:

Private Declare Function SendMessage Lib "user32" Alias "SendMessageA" (ByVal hwnd As Long, ByVal wMsg As Long, ByVal wParam As Long, lParam As Any) As Long

Private Const WM_CHAR = &H102

SendMessage hwnd, WM_CHAR, KeyCode, 0

Thank you! I now have it sending keys to my minimized window!

However I am at a loss as to what "keycode" F1-F12 would be. When I go to MSDN and lookup the Virtual scan code table it says F1 should be 70. However when I send the following it sends the letter 'F'.

Global $WM_CHAR = 0x0102

SendMessage($winhandle,$WM_CHAR, 70, 0);

Func SendMessage($hwnd, $msg, $wp, $lp)

Local $ret

$ret = DllCall("user32.dll", "long", "SendMessageA", "long", $hwnd, "long", $msg, "long", $wp, "long", $lp)

Return $ret[0]

EndFunc

Sorry let me clarify this a bit.

Const $VK_F1 = 0x70

SendMessage($hwnd,$VK_F1);

Func SendMessage($hwnd,$wp)

Local $ret

Local $lp = 0;

$ret = DllCall("user32.dll", "long", "SendMessageA", "long", $hwnd, "long", $WM_CHAR, "long", $wp, "long", 0)

Return $ret[0]

EndFunc

Sends the character "p" to my window. Although 0x70 is listed as virtual key F1 on all the references I could find.

Ideas?

I can send to inactive windows fine. The problem is sending F1-F12.

Wading my way through the help files I discovered as usual most of this work was already done for me, it was just a matter of finding it. I am now down to:

#Include <Misc.au3>

Const $WM_CHAR = 0x0102

Const $VK_F1 = 0x70

_SendMessage($hwnd, $WM_CHAR, $VK_F1,0)

If @error Then

MsgBox(0,"", "_SendMessage Error: " & @error)

Exit

EndIf

But instead of F1, I get "p". If I substitute 0x31 as my hex value I get "1" as expected.

Hey, I'm just wondering (don't have autoit on my laptop), does your example actually work without having to gain focus on the window? Or is the window forced to gain focus before it can send the text?

Sorry for the offtopic-like question, but I'm curious.
