Sending X Keys to a program with a button

How do I send X keys every X seconds to a game?

Help appreciated ~~

Maybe this could help:

Well It kinda worked, thanks!
But however the game doesn't recognize the input so it doesn't really do what I want it to.

Le bump is bump

Try the SendKeys.Send function (not sure if you already did it). If that doesn't work try to import and use the keybd_event / mouse_event API from the user32.dll.
I could be wrong about this if SendKeys.Send somewhere calls the same API so it won't work for you doing that as well then.

In your system folder: (generally) C:\Windows\system32 , but you don't need to look at the file (lol?)...just make the correct declaration in your code and the compiler will (try to) automatically find it.

2 sources you should check:

1. msdn -- to check the function's return type, and the argument(s) type(s). And general notes about the function.
2. pinvoke -- to see an example of the function declaration.

https://www.google.com/search?q=keyb..._event+pinvoke --> http://www.pinvoke.net/default.aspx/user32.keybd_event

C# Signature:

[DllImport("user32.dll")]
static extern bool keybd_event(byte bVk, byte bScan, uint dwFlags,
UIntPtr dwExtraInfo);

or

[DllImport("user32.dll")]
static extern bool keybd_event(byte bVk, byte bScan, uint dwFlags,
int dwExtraInfo);

VB.NET Signature:

<DllImport("user32.dll")> _
Private Shared Function keybd_event(bVk As Byte, bScan As Byte, dwFlags As UInteger, dwExtraInfo As UIntPtr) As Boolean
End Function

or

<DllImport("user32.dll")> _
Private Shared Function keybd_event(bVk As Byte, bScan As Byte, dwFlags As UInteger, dwExtraInfo As Integer) As Boolean
End Function

or

<DllImport("user32.dll", CallingConvention:=CallingConvention.StdCall, _
CharSet:=CharSet.Unicode, EntryPoint:="keybd_event", _
ExactSpelling:=True, SetLastError:=True)> _
Public Shared Function keybd_event(ByVal bVk As Byte, ByVal bScan As Byte, _
ByVal dwFlags As Int32, ByVal dwExtraInfo As Int32) As Boolean
End Function

(..more..)

https://www.google.com/search?q=keybd_event+msdn -->https://msdn.microsoft.com/en-us/lib...=vs.85%29.aspx

VOID WINAPI keybd_event(
_In_ BYTE bVk,
_In_ BYTE bScan,
_In_ DWORD dwFlags,
_In_ ULONG_PTR dwExtraInfo
);
