button vb

There are a few ways to do that for example:

  1. You can find OK button position(FindWindowEx and GetWindowRect), set the cursor position(SetCursorPosition) on it and click(mouse_event) on that or set focus on the button and press Enter(keyb_event).
  2. Send BM_CLICK message to window message translator with the OK button ID.

I suggest you to go with the second approach:

<Runtime.InteropServices.DllImport("user32.dll", SetLastError:=True, CharSet:=Runtime.InteropServices.CharSet.Auto)> _
Public Shared Function SendMessage(ByVal hWnd As IntPtr, ByVal Msg As UInteger, ByVal wParam As IntPtr, ByVal lParam As IntPtr) As IntPtr
End Function

Public BM_CLICK As Integer = &HF5 

SendMessage(`OK BUTTON HANDLE`, BM_CLICK, 0, 0)

You can find the button handle with FindWindowEx
