EDIT: in my application following the process. Assume end user open MS Word document with 5 pages and he presses page up and page down buttons to move within these pages. i want to automate this scenario using c#. currently i have uses UIAutomationClient.dll and UIAutomationTypes.dll. can i uses these?

Answer 1

A very good way for automated sending of keystrokes of all kinds is the AutoIt automation and scripting language . Lots can be done with it, especially page up and page down sending.

I suggest writing an EXE with autoit, which connects itself to the program it will send keystrokes to.

1. Active the application's window using P/Invoke.
2. Call SendWait("C") with any character.

Eg

// Get a handle to an application window.
[DllImport("USER32.DLL", CharSet = CharSet.Unicode)]
public static extern IntPtr FindWindow(string lpClassName, string lpWindowName);

// Activate an application window.
[DllImport("USER32.DLL")]
public static extern bool SetForegroundWindow(IntPtr hWnd);

// Send a series of key presses to the Calculator application. 
private void button1_Click(object sender, EventArgs e)
 {
    // Get a handle to the Calculator application. The window class 
    // and window name were obtained using the Spy++ tool.
    IntPtr calculatorHandle = FindWindow("CalcFrame","Calculator");

    // Verify that Calculator is a running process. 
    if (calculatorHandle == IntPtr.Zero)
    {
        MessageBox.Show("Calculator is not running.");
        return;
    }

    // Make Calculator the foreground application and send it  
    // a set of calculations.
    SetForegroundWindow(calculatorHandle);
    SendKeys.SendWait("111");
    SendKeys.SendWait("*");
    SendKeys.SendWait("11");
    SendKeys.SendWait("=");
}

Answer 3

I think you want to send keystrokes to an application for which you don't have source code.
I can't help you telling you how to do it directly in C#.
But you can do it very easily with AutoIt ; it has a DLL you can reference in C# to do exactly what you need.

Answer 4

Have you read How to send keys instead of characters to a process?

This tells you exactly how to send keys to an application.

Answer 5

// use a windows form and use this list with send keyhttps://www.autoitscript.com/autoit3/docs/appendix/SendKeys.htm I'm pretty sure he's just asking for values of the keys for his SendKey.Send("{}");

Answer 6

in this scenario get the word document to fore ground and then used on screen key board
System.Diagnostics.Process.Start("osk.exe"); and click page up and down buttons using mouse input since for the mouse click need screen coordinates for the page up and down button.

( i tried to detect on screen key board using UI automation. but it did not detect keys of the screen. https://stackoverflow.com/questions/11077738/windows-sdk-inspect-tool-what-are-the-reasons-on-screen-keyboard-does-not-disp couldn't find solution for this problem.so because of that i use this move click method to click the button. )
