Try the following code:
namespace ProcessHandle
{
class Program
{
static void Main(string[] args)
{
Console.WriteLine("Get the process handle example.");
var process = new Process
{
StartInfo = new ProcessStartInfo
("explorer.exe", @"c:\")
};
process.Start();
Console.WriteLine("Process Id: " + process.Id);
Console.WriteLine("Process Name: " + process.ProcessName);
Console.WriteLine("Process Handle(IntPtr): " +
process.Handle.ToString());
Console.ReadLine();
}
}
}
use the above code, you can get the handle of the new opened window,
and then use win api set the position.
