有一个很好的结构,可以控制win32com对象,例如
win32com.client.Dispatch('Word.Application')
win32com.client.Dispatch('Excel.Application')
...等 有没有办法获取可用应用程序的完整列表(* .Application)?
UPD。通过扫描注册表项HKEY_CLASSES_ROOT中的CLSID条目来获取列表的可能解决方案。
from collections import OrderedDict
def myScan():
result = OrderedDict(); i = 0
while True:
try:
a1 = winreg.OpenKey(aReg, winreg.EnumKey(winreg.HKEY_CLASSES_ROOT, i))
if i%1000==0:
print(i,'processing')
j = 0
while True:
try:
#print(j)
a2 = winreg.EnumKey(a1,j)
if a2=='CLSID':
kkkey = winreg.EnumKey(winreg.HKEY_CLASSES_ROOT,i)
vvvalue = winreg.EnumValue(winreg.OpenKey(a1,a2),0)
result[kkkey] = vvvalue
break
j+=1
except OSError:
break
i+=1
except OSError:
break
return result
result = myScan() #candidates
print(len(res)) # 3363
keys_ = list(result.keys())
#retrieving part of result
for i in keys_[:10]:
print(i,'=>',result[i])

通过下面的代码过滤列表(操作较长且可能不安全),可以获得列表:
import pywintypes
for i in range(len(keys_)):
try:
if i%100==0: print(i,'processing')
app = win32com.client.Dispatch(keys_[i]) #possibly unsafe; for example, word.Quit() is necessary to do
finalList.append(keys_[i])
except pywintypes.com_error:
pass
答案 0 :(得分:4)
使用专用的COM浏览器可能会有所帮助。例如,您可以使用与win32com
捆绑在一起的COM浏览器来研究可用的类型库及其接口:
from win32com.client import combrowse
combrowse.main()
