How to set MessageBoxW parameter to disable the Close [x] Button on Message Box using ctypes Python?
To set the MessageBoxW parameter in Python using ctypes to disable the close [x] button on a message box, you need to set the appropriate flag in the dwStyle parameter. Here's an example:
pythonimport ctypes
from ctypes import wintypes
# Constants
MB_OK = 0x00000000
MB_ICONINFORMATION = 0x00000040
MB_SYSTEMMODAL = 0x00001000
MB_TOPMOST = 0x00040000
MB_DISABLE_CLOSE = 0x2000
# ctypes definitions
user32 = ctypes.WinDLL('user32')
MessageBox = user32.MessageBoxW
MessageBox.argtypes = [wintypes.HWND, wintypes.LPCWSTR, wintypes.LPCWSTR, wintypes.UINT]
MessageBox.restype = wintypes.INT
# Call MessageBox function with the desired parameters
MessageBox(None, "Your message here", "Title", MB_OK | MB_ICONINFORMATION | MB_SYSTEMMODAL | MB_TOPMOST | MB_DISABLE_CLOSE)
In this example, we define the constants for the MessageBox style flags, including the MB_DISABLE_CLOSE
flag, which disables the close [x] button. We then load the MessageBoxW
function from the user32
library using ctypes. The function signature and argument types are defined using argtypes
and restype
. Finally, we call the MessageBox
function with the desired parameters, including the MB_DISABLE_CLOSE
flag in the dwStyle
parameter.
Please note that disabling the close [x] button goes against the standard behavior and user expectations. It is generally recommended to avoid modifying the default behavior of standard UI components like message boxes.
