FindWindowEx 找不到按钮

Question

I'm using FindWindow() and FindWindowEx() to control an application. There are 2 buttons in the application, one named "I Agree" and the second "Cancel". I can find the "Cancel" button but can't find the "I Agree" button.

I'm using FindWindow() to find the application, and I store the window's process in the hwnd variable. Then I do this to find and get a button:

hwndChild = FindWindowEx((IntPtr)hwnd, IntPtr.Zero, "Button", "Cancel");

Why can't I find the "I Agree" button, but I can find the "Cancel" button?.

Answer 1

The "I Agree" button is actually "I &Agree". Check out this to find out why. Thanks!
