Summary: makepy generates error during import LabVIEW TLB

Initial Comment:
System: XP Pro SP1
LabVIEW 7.1

the following code generates an error (see below code)

comment from M.Hammond:
>>
"D:\Python24\Lib\site-packages\win32com\client\makepy.py",
>> line 306, in GenerateChildFromTypeLibSpec
>>     __import__("win32com.gen_py." + dir_name + "." +
child)
>> ImportError: No module named _Iapplication
>
>That is probably a bug related to tracking down
dependent typelibs.  Maybe you could add an entry at
sourceforge?

------- Code start
---------------------------------------------
import win32com.client

oLv =
win32com.client.gencache.EnsureDispatch("LabView.Application")


oViTest =
oLv.GetVIReference("D:\Projects\py.lv.test\pytest.vi","",True)
oViTest._FlagAsMethod("Call")                    # as
proposed from M.Hammond

bError    = True                                 # to
preset list object
strResult = ""                                   # to
preset list object

arParNames  = ["strEntry","strOutput","bError"]  #
first and second are strings, third is bool
arParVals   = ["Hello World", strResult, bError] #
first input, second+third output

result = oViTest.Call(arParNames,arParVals)      # call VI

print result                                     # show
changed (OUT) values

del oViLogPrint                                  #
release link to LabVIEW VI (necessary !!)
