Is the order of fields in the ILDASM tree view correct or is the order in the MetaInfo correct? -

-

in trying determine precise order of fields in .net value type, looked both @ ildasm tree view , @ ildasm "metainfo" (i.e., actual il). order of fields in 2 views of data inverse.

for example, tree view of system.runtime.interopservices.filetime lists dwhighdatetime before dwlowdatetime. (i post image, lack enough reputation points here so).

on other hand, here corresponding il, using view>>metainfo>>show! in ildasm:

typedef #1655 (02000678)

typdefname: system.runtime.interopservices.filetime  (02000678) flags     : [public] [sequentiallayout] [class] [sealed] [ansiclass] [beforefieldinit]  (00100109) extends   : 02000009 [typedef] system.valuetype field #1 (04001e2e) -------------------------------------------------------     field name: dwlowdatetime (04001e2e)     flags     : [public]  (00000006)     callcnvntn: [field]     field type:  i4  field #2 (04001e2f) -------------------------------------------------------     field name: dwhighdatetime (04001e2f)     flags     : [public]  (00000006)     callcnvntn: [field]     field type:  i4  ...

which correct order? assume il correct, confirmation. know reason disparity?

looks win32 filetime struct little-endian (low part first). .net version being interop struct, , made interacting native code, pretty have compatible native one.

as reason behind "disparity", note "dwhighdatetime" comes before "dwlowdatetime" in alphabetical order.

on website user have 1 group. , user can change group. it's made user.groups.clear() and user.groups.add(new_group) but it's not efficient, because there 2 sql query: delete, insert. how can change group update query? user , group related each other using manytomanyfield . means intersection table exists relating both entities, , if don't specify model map (using through attribute) django creates 1 you. looking @ sources django.contrib.auth.models see that's case. fortunatly, can access intermediary model using through attribute of manager (in case, user.groups.through ). can use regular model. example: >>> alice = user.objects.create_user('alice', 'alice@example.com', 'alicepw') >>> employee = group.objects.create(name='employee') >>> manager = group.objects.create(name='manager') >>> alice.groups.add(employee) >>> alice.groups.all() [<group: employee...

i need set custom soap header attribute on jax-ws generated webservice client. case webservice calls must go through proxy server requiring specific token (recieved web request header) present in soap request header. e.g.: 1 carserviceservice service = null; 2 service = new carserviceservice(new url(url), new qname(qname); 3 carserviceendpoint port = service.getcarserviceport(); it seems in line 3 wsdl retrieved , call fails due missing security token. 1 point direction on how done? a detailed example has been mentioned here: creating , deploying jax-ws web service on tomcat 6 this article shows how create , use security token .
