Hello there, i have a problem regarding sending keys to MapleStory, that i hope you can help me with.
A little information:
It is coded in C#
I use the SendMessage function to send keys to MapleStory
I send WM_KEYDOWN, WM_CHAR, and WM_KEYUP messages, in that order.

About what i want to happen in the sample code:
When the user presses button1, timer5 is activated
For every tick, the program searches for maplestory,
and when it finds it, the timer is disabled, and the handle is saved in childHandle.

Child window? this is the parent window.
If you play eMS, do FindWindow(NULL, "MapleStory") because the class for eMS isn't MapleStoryClass, and I think FindWindow is hooked now too.

I know it`s the parent window, i just didnt change the variable name after
copying code from a notepad control i made. And this isnt for EMS, its for GMS.
I should perhaps have added that to the first post. Anyway, ill check if it has
to do with the class name.
Edit: I couldnt get it to find the GMS process, so i tried on EMS and it worked.
Only problem now is that when i try to send a message it throws an unhandled exception.
Edit2 : The exception was because there was some sort of error when passing on the handle value. MapleStory does not respond to the messages im sending though.
Edit: Does anyone know if you can even use SendMessage on MapleStory?
And if not, I would be happy to hear suggestions on what i can use instead.

For SendMessage, check out: http://pinvoke.net/default.aspx/user32/SendMessage.html

For getting the window handle; use an internal function. Easier to debug with amongst other things.

Thanks Estx, Ill try using SendInput, but before i go through all the work
of changing the references, could you answer me on wether it works
on MapleStory or not? Regarding FindWindow vs GetProcessByName,
whats the diffrence?

GetProcessesByName() searches for all available processes of the specified string, the [0] after it selects the first found process. You can guarantee that you will find the main window handle using the code I wrote up above as long as the process is running. =)

Using FindWindow(), you need to use GetLastError() to debug if it's failing. The other downside about FindWindow() is that you will need to update your code should MapleStory's Window-title or Class-name change.

And sorry, I updated my post - I misread yours. I updated the link to goto the SendMessage() reference.
