无法在python中使用user32.dll中的ChangeWindowMessageFilter

Question

我尝试在dll（user32.dll调用函数ChangeWindowMessageFilter）

dlluser32 = ctypes.cdll.LoadLibrary('user32.dll')
dlluser32.ChangeWindowMessageFilter(0x0233, 1)
dlluser32.ChangeWindowMessageFilter(0x0048, 1)
dlluser32.ChangeWindowMessageFilter(0x0049, 1)

结果：

^{pr2}$

我怎样才能打好电话？ 我想用这个功能在我的应用程序运行时启用拖放功能，如果它不起作用，有其他方法吗？在

您必须设置调用转换：

from ctypes.wintypes import BOOL, DWORD, UINT

dlluser32 = ctypes.cdll.LoadLibrary('user32.dll')
ChangeWindowMessageFilter = dlluser32.ChangeWindowMessageFilter

# BOOL WINAPI ChangeWindowMessageFilter(_In_  UINT message, _In_  DWORD dwFlag);
ChangeWindowMessageFilter.restype = BOOL
ChangeWindowMessageFilter.argtypes = (UINT, DWORD)

# Now you can call it there...
