AutoHotkey Community

Can you give me example code that opens Notepad and uses SendMessage or PostMessage to put the string “hello” inside the Untitled Notepad window?

If you really want to do that, Send or ControlSend or ControlSetText or such are probably more appropriate.

If you are just looking for examples, searching the forum with the commands will give you plenty of examples...

PS.: please, avoid sending multiple identical messages.

The problem with using Send or ControlSend is that they do not work while the screen is locked. I found from multiple testing that sending keys will not work on a locked workstation. However, posting windows messages under a locked workstation does work. However, I've only been able to post messages to window titles using the following code:

Run Notepad
WinWait Untitled - Notepad
Sleep, 2000
SendMessage, 0xC, 0, "New Notepad Title" ; 0XC is WM_SETTEXT

How do I post a message inside of the window (in the notepad body) instead of the window title?

Thank you.

Specify the ClassNN of the control, eg:

Thank you so much! That worked great! You're the man!

Sorry. You're the woman!!

Do you know how to use PostMessage or SendMessage to send certain keys like {ENTER}? Example code would be great. I really appreciate it. Thank you.

You could try using WM_KEYDOWN, although I am unsure what value lParam should be in this case (a 32-bit integer?). Perhaps someone else can post a working example.

Always curious of the various uses of AutoHotkey: why do you want to use a graphical application like Notepad on a locked workstation?
Perhaps there is other ways of doing what you do...

If you want to send simple keys like Enter or Tab, you can use the special characters: `n (or perhaps `r`n) and `t.

I was using Notepad as a simple test program. I love AutoHotKey but it has problems working while the workstation is under a locked screen. Due to company security policies, I cannot justify having an unlocked workstation. The scripts I created with AutoHotKey will fail under a locked workstation if I try to send keystrokes. Any suggestions?

I was wondering if you can use SendMessage to send a variable. I am using FileRead to read the contents of a text file into a variable. I wanted to use SendMessage to quickly send the string instead of waiting for the meesage to be sent with keystrokes using Send. The following code does not work:

FileRead, OutputVar, C:\test
Run, Notepad
WinWait, Untitled - Notepad
WinActivate, Untitled - Notepad
SendMessage, 0xC, 0, %OutputVar%, Edit1, ahk_Notepad

Any Suggestions on how I can send the contents of my variable inside of the notepad text window. Thank you.

What is ahk_Notepad?

hello , it's my first post in this forum
i wanna know how to post this message in VB6
my reason , it's to put a string on edit but i can't , i have some thing wrong in this command line:
postmessage notepad_handle, wm_char,asc("a"),0

I once had such requirement to simulate keyboard input and also found that SendInput doesn't work when the workstation is locked or a remote desktop connection is disconnected. You will have to use SendMessage/PostMessage along with WM_KEYDOWN/WM_KEYUP messages.

You can try with spyxx (from Visual Studio) and monitor those keyboard messages to learn which parameters you should use.
