It seems to be a dynamic dispatch problem...<br>
You might try Jerry's trick:<br>
<br>
XSI sometimes return objects with an incorrectly set (as per PythonWin
standards) multi-<span id="st" name="st" class="st0">dispatch</span>
interface.<br>
<br>
The way to work around that is to re-wrap the object in a <span id="st"
name="st" class="st0">dynamic</span> <span id="st" name="st"
class="st0">dispatch</span>. This allows you to skip the
Application.GetValue:<br>
<br>
def dispFix( badDispatch ):<br>
import win32com.client.<span id="st" name="st" class
="st0">dynamic</span><br>
# Re-Wraps a bad <span id="st" name="st" class="st0"
>dispatch</span>
into a working one:<br>
return win32com.client.<span id="st" name="st" class
="st0">dynamic</span>
<div id="mb_6">.<span id="st" name="st" class="st0">Dispatch</span>
(badDispatch)<br>
<br>
# Let's see if this works:<br>
Application.CreatePrim("Sphere", "MeshSurface", "", "")<br>
Application.ApplyHairOp
("sphere", "")<br>
oHair =
Application.GetValue("hair").ActivePrimitive.ConstructionHistory.Find(
"HairGenOp")<br>
try:<br>
Application.LogMessage(oHair.Parameters['EmitterMeshSubdlevel'].Value)
<br>
except:<br>
Application.LogMessage("Incorrect <span id="st" name
="st"
class="st0">dispatch</span> pointer")<br>
oHair = dispFix(oHair)<br>
Application.LogMessage(oHair.Parameters['EmitterMeshSubdlevel'].Value)
<br>
<br>
# or, as a single long line:<br>
<br>
dispFix(Application.GetValue("hair")<br>
.ActivePrimitive.ConstructionHistory<br>
.Find("HairGenOp")<br>
).Parameters['EmitterMeshSubdlevel'].Value = 1
<br>
<br>
If
that really really annoys you and you don't want to dispFix at all,
there is a way to make sure everything works, but you need to modify a <span
id="st" name="st" class="st0">Python</span> file to always return <span
id="st" name="st" class="st0">dynamic</span> dispatches:<br>
<br>
Change %PYTHONPATH%\Lib\site-packages\win32com\client\__init__.py
<br>
<br>
Look for the function called __WrapDispatch<br>
<br>
And comment all lines except the last one that begins with "return <span
id="st" name="st" class="st0">dynamic</span>.<span id="st" name="st"
class="st0">Dispatch
</span>( ... "<br>
<br>
Of course it is always a good idea to backup files you are about to
modify.<br>
<br>
<br>
Cheers!<br>
