Hello all.
I am developing application in python on Windows CE which needs connection to the internet (via GPRS/EDGE). When I turn on the device, the internet connection is not active. It becomes active if I open internet explorer.
I would like to activate connection in my application. I'm trying to do this with RasDial function over ctypes library, but I can't get it to work. Is this the right way or I should do something else?
Below is my current code. The ResDial function keeps returning error 87 – Invalid parameter. I don't know anymore what is wrong with it.
I would really appreciate any kind of help. Thanks in advance.

try:
param = RASDIALPARAMS()
param.dwSize = 1462 # also tried 1464 and sizeof(RASDIALPARAMS()). Makes no difference.
param.szEntryName = u"My Connection"

ras = windll.coredll.RasDial(None, None, param, c_ulong(0xFFFFFFFF), c_voidp(self._w32_hWnd), byref(iNasConn))
print ras, repr(iNasConn) #this prints 87 c_ulong(0L)
