It depends on whetehr the other program is a console program. If it is a console program then you might be able to redirect standard input. If it is not a console program then there are alternatives but the relevant one depends on the type of control that the space character is going to.

OK, to avoid the error, change it to this:

if(e.Result.Text=="Time")
{
Process p = Process.Start("SomeProgram.exe");
p.WaitForInputIdle();
SendKeys.Send(" "); // send a space
// any other statements involving 'p'
}

Do you have that line within an 'if', 'while' etc. statement?

Can you post the lines above the one giving the error.

As long as the other program's main window has the input focus - which it should have when you've just launched it - then you should be able to send it keystrokes using SendKeys:

using System.Diagnostics;
using System.Windows.Forms;

// ...

Process p = Process.Start("SomeProgram.exe");
p.WaitForInputIdle();
SendKeys.Send(" "); // send a space
i am getting error like embedded statement cannot be a declaration or labelled statement while declaring Process p = Process.Start("some exe");

If you have source for Program.exe then you can skip the step where the program is having the statement that is waiting for the user's input.

if you don't have that this could be possible through the automation scripts created using vbscript. I've never used them but heard of it.

Thanks.
