If you having trouble with someone else's code, why are you not asking them about it? What do you expect from someone here?

I think that code does not work with game so expect new solution for me most probably using DirectX, second thing I need quick solution and I guess no other community is as quick as code project with million following it.
thanks

Not enough information. And I agree with ThePhantomUpvoter.

It won't work. The code you've written to send keyboard messages to other applications is probably using SendKeys. This doesn't work with anything running on DirectX, which is most games. DirectX looks at the keyboard directly, bypassing the Windows messaging functions that normal applications, and SendKeys, uses.

AFAIK, there is no way to make a DirectX compatible equivilent of SendKeys, at least not without writing a device driver.

I found solution for my problem.
I downloaded " InputManagerSendingMessages example" from link
Download
InputManager library - Track user input and simulate input (mouse and keyboard)[^]
and modified a bit as given

C#

private void WriteExampleText_Click(object sender, EventArgs e)
        {
           
            Thread.Sleep(10000); 
            Keyboard.KeyDown(Keys.Up);
            Thread.Sleep(1000);
            Keyboard.KeyDown(Keys.Left);
            Thread.Sleep(1000);
            Keyboard.KeyDown(Keys.Right);

        }
Run this code and start the game(now code will run in the background), after 10 second car will get command. 
 Above code gives perfect command to ActiveX game such as "Need For Speed Underground"
I am thankful to the author, code project and experts replying to  naïve programmer like me.
