Hacking the window message queue

[t3hL33Tn00b]

hi there guys

im new to the world of GUI's, just started learning about them... and i was wondering if it is possible to send messages to some window's queue from another window..

example: from one window you send the message to the other window to say press a button or something. Also, if its possible to know the ID of the message(perhaps using MHS)...

its hard to put in words since i'm totaly newb to this, but i think you got the idea of what im trying to do

lastly, if it is possible, then can i send a message to some game's message queue? (in order to make the character run, jump, etc)

thanks in advance for the attention

SendMessage() and PostMessage(), found both in the Windows® API and in the MHS script.
Using the MHS script will allow you to test them before making a full C++ project.


You need to have the handle to the target window.
This is typically found using FindWindow(), also in the Windows® API and in the MHS script.

An example can be found in the help file in the Minesweeper examples.
Search for “extern”.

example: from one window you send the message to the other window to say press a button or something. Also, if its possible to know the ID of the message(perhaps using MHS)...

Although you can send WM_KEYDOWN and WM_KEYUP messages, you are better-off using KeyboardEvent() (MHS script) or SendInput() (Windows® API and MHS script).
A list of all Windows® WM_* messages can be found in the help file in the Predefined Enums section.

Hi there again

Im going to be bothering you guys another time..

I've ran into a problem now, i can close windows and change the title bar text, but I've been unable to send keystrokes.. Im practicing with notepad.

I do know that i've got to get the handle of the child window "Edit", i do that but when i send WM_KEYDOWN for example, nothing happens at all.

I tried WM_CHAR also, but no success. its kinda confusing all that stuff

I've been googleing all sorts of stuff but i cant get this to work.. Does that has anything to do with focus or something? btw im interested in sending keystrokes because i want to send them to games in order to perform an action in the game (jump, fire, etc.)

if any of you gods of programming guys can head me to the right path I would greatly apreciate

As mentioned before, KeyboardEvent() in the MHS script or SendInput() in the Windows® API. SendInput() also works in the MHS script.

There is an example on botting in the help file.
Search for Minesweeper.
