Open a new instance of Autocad via Python -


does have experience using python autocad? i'm trying, test see if can open new instance of autocad via python , though pyautocad worked (feel free offer other suggestions, if have any)

anyway based on doc (https://pypi.python.org/pypi/pyautocad/#downloads) - says these lines of code should it, nothing's happened of yet.

    pyautocad import autocad, apoint     acad = autocad()     acad.prompt("hello, autocad python\n"

just these lines of code should generate info on commandline instead results in 50 lines worth of traceback (which can post if anyone's interested) - ideas?

traceback (most recent call last): file "<pyshell#5>", line 1, in <module> acad.prompt("hello, autocad") file "c:\python27\lib\site-packages\pyautocad\api.py", line 153, in prompt self.doc.utility.prompt(u"%s\n" % text) file "c:\python27\lib\site-packages\pyautocad\api.py", line 65, in doc return self.app.activedocument file "c:\python27\lib\site-packages\pyautocad\api.py", line 54, in app self._app = comtypes.client.getactiveobject('autocad.application') file "c:\python27\lib\site-packages\comtypes\client\__init__.py", line 180, in getactiveobject obj = comtypes.getactiveobject(clsid, interface=interface) file "c:\python27\lib\site-packages\comtypes\__init__.py", line 1165, in getactiveobject oledll.oleaut32.getactiveobject(byref(clsid), none, byref(p)) file "_ctypes/callproc.c", line 941, in getresult windowserror: [error -2147221021] operation unavailable

after adding vba module, traceback reads:

traceback (most recent call last):   file "<pyshell#4>", line 1, in <module>     acad.prompt("hello")   file "c:\python27\lib\site-packages\pyautocad\api.py", line 153, in prompt     self.doc.utility.prompt(u"%s\n" % text)   file "c:\python27\lib\site-packages\pyautocad\api.py", line 65, in doc     return self.app.activedocument   file "c:\python27\lib\site-packages\pyautocad\api.py", line 54, in app     self._app = comtypes.client.getactiveobject('autocad.application')   file "c:\python27\lib\site-packages\comtypes\client\__init__.py", line 183, in getactiveobject     return _manage(obj, clsid, interface=interface)   file "c:\python27\lib\site-packages\comtypes\client\__init__.py", line 188, in _manage     obj = getbestinterface(obj)   file "c:\python27\lib\site-packages\comtypes\client\__init__.py", line 112, in getbestinterface     interface = getattr(mod, itf_name) attributeerror: 'module' object has no attribute 'iacadapplication'

now after deleting comtypes' "gen" folder per @reclosedev, autocad opens string of text still not appear on command line - traceback reads:

traceback (most recent call last):   file "<pyshell#4>", line 1, in <module>     acad.prompt("hello")   file "c:\python27\lib\site-packages\pyautocad\api.py", line 153, in prompt     self.doc.utility.prompt(u"%s\n" % text)   file "c:\python27\lib\site-packages\pyautocad\api.py", line 65, in doc     return self.app.activedocument   file "c:\python27\lib\site-packages\pyautocad\api.py", line 59, in app     self._app.visible = self._visible   file "c:\python27\lib\site-packages\comtypes\client\dynamic.py", line 116, in __setattr__     dispid = self._comobj.getidsofnames(name)[0]   file "c:\python27\lib\site-packages\comtypes\automation.py", line 643, in getidsofnames     self.__com_getidsofnames(riid_null, arr, len(names), lcid, ids) comerror: (-2147418111, 'call rejected callee.', (none, none, none, 0, none))

have considered ironpython?

http://through-the-interface.typepad.com/through_the_interface/2009/03/using-ironpython-with-autocad.html

here's quick example of how leveraged:

import clr import system  system import type, activator  acapp = activator.createinstance(type.gettypefromprogid("autocad.application")) acapp.visible = 1 acapp.activedocument.sendcommand("(princ \"hello world python!\")(princ)\n")

obviously progid correspond whichever version of autocad opened last.

c# - Send Image in Json : 400 Bad request -

from android trying send image class of data, iis webservice. (c#) the problem 400 bad request . the image being encoded base64 . , placed json rest of class elements. my guess base64 not valid inside json. server not understand it. if set string "" , post accepted fine. so question is, how make base64 valid within json array? ( tried url.encode no success). or how should send image android webservice? gson gson = new gson(); string json = gson.tojson(record); // record has param { string base64photo } how big image? i'm pretty sure surpassing iis json size limit (default 4 mb). check http://geekswithblogs.net/frankw/archive/2008/08/05/how-to-configure-maxjsonlength-in-asp.net-ajax-applications.aspx or http://www.webtrenches.com/post.cfm/iis7-file-upload-size-limits good luck!
