wcf binding - WCF netTCPBinding -

-

wcf's nettcpbinding "secured default". understand means that..

  • callers authenticated using windows credentials.
  • messages signed
  • messages encrypted.

however, can set basic wcf client service set on localhost. authentication work on same machine, how signing , encryption work?

wcf needs certificate sign , encrypt messages. if dont have certificate how service manage work? how message - going same machine signed , encrypted.

thanks.

by default nettcpbinding uses transport security, default characteristics list.

signing , encryption of messages in context not mean same thing in message security. rather means packets of data sent on network transport signed , encrypted. not rely on certificates. done security providers installed in operating system on sending , receiving machines, invoked via sspi (security support provider interface) - same mechanism involved, example, when domain credential used access resource such file on different machine on network.

before application data sent on connection, binding orchestrates sspi handshake between sender , receiver, specifying negotiate security package (this chooses either ntlm or kerberos actual security protocol, depending on capabilities of respective host machines). security tokens exchanged on connection part of handshake, @ end of 2 sides' security providers have agreed session keys use in signing , encryption of ensuing application messages.

c# - How to set Z index when using WPF DrawingContext? -

how set z-index drawing object when using drawingcontext.drawxxx() methods? the object drawn last have higher z index. can't change index of drawn objects. way draw in order. if using wpf (as placed tag), can use, example, canvas control. create shapes need like polyline obj = new polyline(); //... // ... set properties of obj and add them canvas uielementcollection: yourcanvasname.children.add(obj); //or yourcanvasname.children.insert(i, obj); first items of collection have higher z index. advantages in way: no need redraw on window changes, can anytime move objects , change order.

razor - Is this a bug in WebMatrix PageData? -

i think may have found bug in webmatrix's pagedata, not sure. concerns how pass data partial page calling page. in webmatrix documentation (tutorials, e.g. " 3 - creating consistent look ", , example code), pagedata recommended mechanism pass data between pages (e.g. content page layout page, or partial page). however have found not work other way, pass data partial page calling page. modifying or adding entries in pagedata in partial page, not seem calling page. cutting right down simplest possible example, in test page may have this: @{ pagedata["test"] = "initial entry"; } <p>before calling partial page, test value @pagedata["test"]</p> @renderpage("_testpartial.cshtml") <p>after returning calling page, test value @pagedata["test"]</p> and in _testpartial.cshtml page might have this: @{ pagedata["test"] = "modified entry"; } <p>in partial page...

i need sort through array , sort each individual row in array in ascending order. doesn't seem going (surprise!) keep getting hit 2 errors: a2101: cannot add 2 relocatable labels , a2026: constant expected here's sort, makes sense me, think i'm still trying implement high-lvl language techniqes assembly. there way around not being able use relative values? (the array 7 rows 9 columns, btw). mov cx, 7; cx = number of rows outer: ; outer loop walk through rows push cx mov cx, 9 mov row, cx ;rows middle: ; middle-loop walk through columns push cx sub cx, 1 ;cx = cx-1 mov column, cx ;columns inner: ;inner loop - compare , exchange column values cmp marray[row*9 + column], marray[row*9 + column+1] xchg marray[row*9 + column+1], marray[row*9 + column] ; compare , exchange values marray table inc column loop inner pop cx loop mid...
