Send Function key to a game
Send Function key to a game
Hello every one 
i have tried this code and did not work
also i have tried this code and did not work too
if i send letters or numbers both are working with no problems but not Function keys
to make sure i have tried windows 7 On screen keyboard it can send Function keys
also i tried some free virtual keyboard all can send numbers and letters but not Function keys
except This FVK (OSK) it is like windows 7 OSK both can send Function keys to the game
sorry for this long story but i want it to be clear
My question : is there any code (VB2010) that can send Function keys to the game like windows 7 OSK ?
I hope some can do it
i have tried this code and did not work

Which game you are trying to send the keys to?
There are games that blocks direct input if not from keyboards.
Also, there are classes that will not work on DirectX games.
There are also games the blocks SendInput, SendMessage, PostMessage & VK_Keys.
If you are trying to make a bot, its best you work on OCR & Look for Interceptor.dll.

how do i know if it is blocking - direct input if not from keyboards
i think it is not blocking because Windows 7 OSK and FVK that i download it both are working i can send Function keys with it
Windows 7 OSK and FVK >>> which way do you think are using to make it
SendInput or SendMessage or PostMessage or VK_Keys
Can you write an example code for each way of these ( SendInput, SendMessage, PostMessage and VK_Keys )
also what about this ( Interceptor.dll )
Thanks
There are ways.
1. Try AutoIt or AutoHotkey
2. Im using https://www.kbdedit.com/manual/low_level_vk_list.html
3. https://github.com/jasonpang/Interce...ster/README.md
Each of those are different approach but achieves the same thing, automation of Key Sends & Mouse Inputs.
VB.NET
For VK_Keys, you have to declare it as constants.
Calling it like this:
FOR AUTOIT
Reference AutoItX64.dll into your project and call it like this:
Import AutoIt Library first
Then, declare a variable that links to the AutoItX3Lib
And Call it like this:
{2} is the Raw Key for #2.
Which means, it sends Keys.2 directly to the game window.
Which means, it works EVEN if the window is hidden or minimized.

Code:
#Region "Mouse & Key Events Declaration"
Declare Function mouse_event Lib "user32.dll" Alias "mouse_event" (ByVal dwFlags As Int32, ByVal dX As Int32, ByVal dY As Int32, ByVal cButtons As Int32, ByVal dwExtraInfo As Int32) As Boolean

Function MakeDWord(ByVal LoWord As Integer, ByVal HiWord As Integer) As Long
MakeDWord = (HiWord * &H10000) Or (LoWord And &HFFFF&)
End Function
#End Region
Code:
Const WM_KEYDOWN As Integer = &H100 Const WM_KEYUP As Integer = &H101 Const VK_TAB As Integer = &H9 'Sample key (TAB Key)
Code:
Dim GameWin As IntPtr = FindWindow(Nothing, "YourTargetGameWindowName")
SendMessage(gameWin, WM_KEYDOWN, VK_TAB, 0)
SendMessage(gameWin, WM_KEYUP, VK_TAB, 0)
Reference AutoItX64.dll into your project and call it like this:
Import AutoIt Library first
Code:
Imports AutoItX3Lib
Code:
Dim au3 As New AutoItX3
Code:
'ControlSend ( "title", "text", controlID, "string" [, flag = 0] ) '<= The AutoIt Syntax
au3.ControlSend("TargetGameWindowName", "", "", "{2}") '<= The Vb.net AutoIt Syntax
Which means, it sends Keys.2 directly to the game window.
Which means, it works EVEN if the window is hidden or minimized.

Firstly Thanks for your reply
Secondly explanation of what i have done
i tried every way you told me about it
AutoIt : Error: A reference could not be added. Please make sure that the file is accessible, and that it is a valid assembly or COM component
i tried use regsvr32 AutoItX3.dll > so i can add it as reference
i used your code to test it >>> it is working also but letters numbers only it can't send Function keys to the game
AutoHotkey : this time the Error: A reference could not be added > did not appear and i could add it as reference with no problems
but i tried use Import AutoHotkey Library i could not there is nothing so i could not test it
Interceptor : Error: A reference could not be added. Please make sure that the file is accessible, and that it is a valid assembly or COM component
this time i tried use regsvr32 interception.dll > so i can add it as reference
another error appear >>> the module was loaded but the entry-point dllregisterserver was not found Make sure that "interception.dll" is a valid DLL or ocx file and then try again
i tried again to add it as a reference same error appear so i could not test it too
SendMessage : i tried this way it does not send any thing not even numbers or letters
Code:
Dim GameWin As IntPtr = FindWindow(Nothing, "YourTargetGameWindowName")
SendMessage(gameWin, WM_KEYDOWN, VK_TAB, 0)
SendMessage(gameWin, WM_KEYUP, VK_TAB, 0)
Code:
Dim GameWin As IntPtr = FindWindow(Nothing, "YourTargetGameWindowName")
PostMessage(gameWin, WM_KEYDOWN, VK_TAB, 0)
PostMessage(gameWin, WM_KEYUP, VK_TAB, 0)
Try sending Function Keys using Autoit without making it a Raw Key.
So just Send("F1") see if that works.
As for PostMessage / SendMessage, like I said, declare the Key first as constant.
Const VK_F1 As Integer = &H70
So just Send("F1") see if that works.
As for PostMessage / SendMessage, like I said, declare the Key first as constant.
Const VK_F1 As Integer = &H70
for GTA it was enough to do a break, between calling up and down
Code:
keybd_event(0x57, xKey, 0, 0) Sleep(50) keybd_event(0x57, xKey, KEYEVENTF_KEYUP, 0)
Its also possible that he is sending the keys to wrong window.

Do not believe me
it is easy
Any one can test it by downloading the game
Link of game
