If you want to send text to notepad try this:

//WM_PASTE = 0x302
//Copy the String/Text what you want to Clipboard,
//PostMessage Send you Clipboard via Paste to the Handle what you choose
Clipboard.SetText(text);
PostMessage(p.MainWindowHandle, WM_PASTE, 0, 0);

Do not forget the "thanks" button if this is what you wan't

why would u need to copy the text to ur clipboard before..? kinda senseless

[SwarN]

Because PostMessage only let you push 1 button,
so with this method you only have to call the method 1 time's.

If you have a better solution you can post it here, but dont spam in this thread! he want help and no spam!

There are many ways on how to use Post-/SendMessage.

[Xijezu]

        [DllImport("user32.dll", CharSet = CharSet.Auto, SetLastError = false)]
        public static extern IntPtr SendMessage(IntPtr hWnd, uint Msg, int wParam, IntPtr lParam);

        SendMessage(Handle, 0x000C, 0, Marshal.StringToHGlobalAuto("Message goes here"));

If I remember right, 0x000C was WM_SENDTEXT.
That's what I'm using.

[Kraizy​]

Well, its VB.NET but that should not be a big problem..

And yes, 0xC is WM_SETTEXT

[Cyberghost77]

WM_PASTE = 0x302

thats not a good solution but the only one works with PostMessage

-----------
hm tryed it wont work dunno why :S

public static void sendstring(string text, string prozess)
{
Process[] procs = Process.GetProcessesByName(prozess);
proccID = procs[0].Id;
Process p = Process.GetProcessById(proccID);
Clipboard.SetText(text);
PostMessage(p.MainWindowHandle, WM_PASTE, 0, 0);
}

[Kraizy​]

Any error message?

[SwarN]

on which process do you want to send text?
if it's a mmorpg there are much more problem's. Test it with notepad

[Cyberghost77]

i want to send it to the login from League of Legends.
Sending keys with

Sendkeys.send...

works great but i wanna login background

[SwarN]

That is what i mean,

MMORPG's are very different from normal Applications like notepad or textpad etc...

with Send/PostMessage you will have no success, try another method, like funktion hooking or send login packets etc...

Or you make your LoL 1 Sek to the aktiv form an send all keystrokes within 1 second and reaktivate the form where you are before. Because it's only the login :/

[Cyberghost77]

my problem is iam able to send keys like thw 2th method in my first post ...
u know any good methodes ? my u can help me :O

---------------- edit --------------------

think u are right but just because if the window is not active the textbox ist also not aktive

[SwarN]

yes, you don't have a focus to the Nickname field or the Password field.

You can try to Set this via ProcessRead/Write Memory,
and then only send the "Return" for Login.

i don't play LoL so i can't help you exactly only can give you "tips"
