lol why is the first one NULL that should to be handle for whatever you want to send PostMessage too.. like a game or something.. it doesnt just work in air.
Also WM_KEYUP should have which key you want to press up as well you can't just do it with a invisible key!

Can hWnd be NULL?
and since you're exiting right after the PostMessage you won't be able to see the results.

You obviously know nothing about messages. 
That is why, it won't work.

1. Why are you pointlessly sleeping?
2. NULL would work as far as I know, you would send a message to yourself.
but even so, you're not sending anything meaningful.

Post count has nothing to do with a persons knowledge.

Read up on how to use the API. Next time, do not just post code and say "doesnt work" as the topic name. Instead, give us some info on what doesn't work, what you are trying to accomplish, etc.

I apologize Wiccan, what I meant to say was its not even compiling.
updated version
| Code: | #include <iostream>
#include <windows.h>
int main()
{
PostMessage( Notepad, WM_KEYUP, 0, 0 );
system("pause"); //dont flame plz
return 0;
} |
I get this error
| Code: | ------ Build started: Project: NegiBot, Configuration: Debug Win32 ------
Compiling...
NegiBot.cpp
.\NegiBot.cpp(6) : error C2065: 'Notepad' : undeclared identifier

HWND != text string. You need to FindWindow+FindWindowEx. Notepad Window -> Edit Control.

c++ doesn't know what the word Notepad means..
C++ works of numbers not letters you gotta do something like
HWND hNotepad = FindWindow(NULL, "my window title");
PostMessage( hNotepad , WM_KEYUP, 0, 0 );
something like that or use FindWindowEx to go deeper

or just change your settings to use ANSI. Also this won't work on notepad. Once you findwindow you ahve to findwindowex for the EDIT control.

What's the point of WM_KEYUP if theres no key specified and no WM_KEYDOWN before it...

Put L in front. Take out BOOL in front of PostMessage.
