WinCE Binaries

Anonymous — Sat, 01 Jul 2006 00:20:58 -0000

A build is available for PythonCE 2.4.3 from the
PythonCE project site, but not here. Could this be
done to avoid future confusion? - Tod

Any Win64 port planned in future ?

Anonymous — Tue, 07 Feb 2006 08:12:15 -0000

Hello,

I'm using Python as a scripting language for our
software. Because our APS software needs a lot of RAM
we ported to 64bit (Win64) including Python. It all
works fine, but we have got the problem that ctypes
isn't compilable because of inline assembler usage in
the FFI (isn't supported on our compiler). Are there
sources available that don't use inline assembler ?

"import ctypes" and "Py_Initialize();"

Anonymous — Tue, 08 Nov 2005 18:04:08 -0000

If this code is launched 5 times, inside one C++
application the application crash:

Py_Initialize();
PyRun_SimpleString("import ctypes");
Py_Finalize();

Any idea for solution?

Cheers,
VV

Handling VARIANT [in,out] arrays

Anonymous — Mon, 25 Jul 2005 07:02:53 -0000

How is such a COM-Function called from Python?

[id(0x000003f7), helpstring("Call the VI as
a subVI"), helpcontext(0x000029a6)]
void Call(
[in, out, optional]
VARIANT* paramNames,
[in, out, optional]
VARIANT* paramVals);

I tried the following:
VARIANT5 = VARIANT *5
parmNames = VARIANT5()
v=VARIANT()
v.value = c_char_p("hostname42")
parmNames[0]=v
v=VARIANT()
v.value = "port"
parmNames[1]=v
v=VARIANT()
v.value = "Model VI Path"
parmNames[2]=v
v=VARIANT()
v.value = "Model DLL Path"
parmNames[3]=v
v=VARIANT()
v.value = "MDL_Path"
parmNames[4]=v
result = VARIANT5()
for i in range(0,4):
v=VARIANT()
result[i]=v

self.initVI.Call(byref(parmNames),byref(result))
However i got the following exception:
Traceback (most recent call last):

What did I make wrong?

Data structure

Anonymous — Mon, 11 Aug 2003 08:34:16 -0000

Hi there,
I found ctypes is great soft but it miss the possibility to
use data struct so many useful function cant work (for
example retrieving process is impossible).

Please ad soon struct in function (as cmd and as result)
and ctypes will be one of the most usefull programming
facility for python (at least on win32 plat).

Thanks
Major respect,
IAD
