object = InvokeTypes(dispid, lcid
, wFlags
, resultTypeDesc
, typeDescs
, args
)
Invokes a DISPID, using the passed arguments and type descriptions.
Parameters
dispid : int
The dispid to use. Please see PyIDispatch::Invoke.lcid : int
The locale ID. Please see PyIDispatch::Invoke.wFlags : int
Flags for the call. Please see PyIDispatch::Invoke.resultTypeDesc : tuple
A tuple describing the type of the
result. See the comments for more information.typeDescs : (tuple, ...)
A sequence of tuples describing
the types of the parameters for the function. See the comments
for more information.args : object, ...
The args to the function.Comments
The Microsoft documentation for IDispatch should be used for all
params except 'resultTypeDesc' and 'typeDescs'. 'resultTypeDesc' describes
the return value of the function, and is a tuple of (type_id, flags).
'typeDescs' describes the type of each parameters, and is a list of the
same (type_id, flags) tuple.

Description
|
|
|
| type_id | A valid "variant type" constant (eg, VT_I4 | VT_ARRAY, VT_DATE, etc - see VARIANT at MSDN). |
| flags | One of the PARAMFLAG constants (eg, PARAMFLAG_FIN, PARAMFLAG_FOUT etc - see PARAMFLAG at MSDN). |
Example
An example from the makepy generated file for Word
class Cells(DispatchBaseClass):
...
def SetWidth(self, ColumnWidth=..., RulerStyle=...):
return self._oleobj_.InvokeTypes(202, LCID, 1, (24, 0), ((4, 1), (3, 1)),...)
The interesting bits are
resultTypeDesc: (24, 0) - (VT_VOID, <no flags>)
typeDescs: ((4, 1), (3, 1)) - ((VT_R4, PARAMFLAG_FIN), (VT_I4, PARAMFLAG_FIN))
So, in this example, the function returns no value and takes 2 "in"
params - ColumnWidth is a float, and RulerStule is an int.
