I have a sample winform application called (Myapp.exe) with a form and a button. I will launch this application (.exe) from another application.

My questions here is. After launching the (Myapp.exe) application from another application (console or winform), i need to access the state of the button in (Myapp.exe) application. How this is achieved?? Is it possible? Can any one please me on this.

It's possible, but you need to realise that from an outside point of view a button is a window (with a handle) whose parent is the form (also a window with a handle), and its state may not be accessible with quite the same useful names as the properties in WinForms show it.

For example, this C++ code will work on a C# app even if that app is being run through the debugger: 

HWND hwndCSharp = ::FindWindow(NULL,_T("Form1") ); 
if (hwndCSharp != NULL) 
{
    // Walk the window's child windows (controls / views): 
    HWND hwndChild = ::GetWindow(hwndCSharp, GW_CHILD); 
    while (hwndChild != NULL) 
    {
        // Get state here... 

        hwndChild = ::GetWindow(hwndChild, GW_HWNDNEXT); 

    }

}

this has already been discussed in stack.so here is just a same code just give it try.

  Application application = Application.Launch("Myapp.exe");
       Window window = application.GetWindow("bar", InitializeOption.NoCache);

       Button button = window.Get<Button>("button1");
       button.Click();
