新人求助wxPython中嵌入ActiveX控件的问题

Answer 1

我用wx.lib.activexwrapper 中的 MakeActiveXClass类在界面中嵌入ActiveX控件，一般的控件都没有问题
下面是我的代码：
import wx
from wx.lib.activexwrapper import MakeActiveXClass
import win32com.client.gencache as win32

mediaControl = win32.EnsureModule('{6BF52A50-394A-11D3-B153-00C04F79FAA6}',0,1,0)

print dir(mediaControl)
if mediaControl is None:
raise ImportError("Can't load wmp. Make sure you have wmp installed.")

class MyFrame(wx.Frame):
def __init__(self):
wx.Frame.__init__(self,None,-1,'MediaPlayer',(50,50),(800,600)) #初始化一个窗口
p=wx.Panel(self)
ActiveXWrapper =MakeActiveXClass(mediaControl.WindowsMediaPlayer)
self.med = ActiveXWrapper(p,-1)

if __name__=="__main__":
app=wx.PySimpleApp()
media1=MyFrame()
media1.Show()
app.MainLoop()

运行结果:
Traceback (most recent call last):
File "D:\JQC\Python\IDE\Lib\site-packages\pythonwin\pywin\framework\scriptutils.py", line 310, in RunScript
exec codeObject in __main__.__dict__
File "D:\pyhtontest\Mymedia_client_3.py", line 58, in ?
media1=MyFrame()
File "D:\pyhtontest\Mymedia_client_3.py", line 25, in __init__
self.med = ActiveXWrapper(p,-1)
File "D:\JQC\Python\IDE\lib\site-packages\wx-2.8-msw-unicode\wx\lib\activexwrapper.py", line 119, in axw__init__

File "D:\JQC\Python\IDE\Lib\site-packages\pythonwin\pywin\mfc\activex.py", line 23, in CreateControl
self.__dict__["_obj_"] = win32ui.CreateControl(clsid, windowTitle, style, rect, parent, id, None, False, lic_string)
win32ui: The window can not be created as it has an invalid handle

同样方法用在别的控件上不会出错，我还试过日历控件，Quicktime，realplayer（结果嵌入的是音频的）

我试过别的方法嵌入media player控件，比如用wx.media.MediaCtrl,这可能是最简单的方法了，但是只能载入WMP6.4的，6.4在连接http服务器播放流媒体时会出错。
