Using SendMessage to Simulate Mouse Clicks
What I need
Simulate messages (mostly mouse, but keyboard too) without moving the cursor . The message goes to the focused window (I want the windows to be minimized first, but I haven't found how to do that, so I use SetForegroundWindow
to focus it).
What i found
In this question, I realized that I need to use pInvoked from user32.dll
. Also I found a small sample code, but it didn't work.
I also found this similar question. The guy is using mouse_event
but it is outdated. This feature takes X and Y crusts in mickey. I tried converting my coordinates (using SendMessage
) but I failed.
An example of Icanhaz?
Sure. It will open notepad.exe
and I need to right click on the button located at (1210, 460).
What i tried
Based on the sample I found here, I made this code:
IntPtr hWnd = (IntPtr)FindWindow("notepad.exe", null);
SetForegroundWindow(hWnd);
var screenPoint = this.PointToScreen(new Point(1210, 460));
var handle = WindowFromPoint(screenPoint);
if (handle != IntPtr.Zero)
{
//Right Button Down
SendMessage(handle, 0x0204, IntPtr.Zero, IntPtr.Zero);
//Right Button Up
SendMessage(handle, 0x0205, IntPtr.Zero, IntPtr.Zero);
}
I also tried using my previous handle hWnd
in SendMessage
, but didn't work. You can find all the code here .
Thanks in advance.

Raymond Chen wrote a blog post just for you: You cannot simulate keyboard input with PostMessage . I know you want a mouse, not keys, and you are using Send not Post, but the exact same problems apply to you. Read the link. Fortunately, it also contains a solution: use SendInput
.
Synthesizes keystrokes, mouse movements, and button presses.

This is some kind of mouse and keyboard manipulator made when I was younger to find the color on the game screen and right click + option: P
Maybe some code can help you, even if it's in French ...

If I understand correctly, you want to inject a click event inside the application without moving the mouse like a game bot, so the user doesn't see that the summation is using his mouse and keyboard ...
If im right then take a look at the answer on this link, this might be what you want ...
its in C ++, but not a very big question I think ...
