printing - How to show printer preferences window having "Apply" button to save changes permanently in c#? -


i able show printer preferences window using code below:

string printername = cmbslideprinter.selecteditem.tostring(); bool islandscape = cmbslideprintorientation.selectedindex == 0;  //print method 3 using (var printqueue = new printqueue(new printserver(), printername)) {     var printdialog = new printdialog();     printdialog.printqueue = printqueue;      printdialog.printticket.pageorientation = islandscape ? pageorientation.landscape : pageorientation.portrait;      //set printer settings     printticketconverter ptc = new printticketconverter(printqueue.fullname, printqueue.clientprintschemaversion);     intptr mainwindowptr = new windowinterophelper(this).handle;     byte[] mydevmode = ptc.convertprinttickettodevmode(printdialog.printticket, basedevmodetype.userdefault);     gchandle pinneddevmode = gchandle.alloc(mydevmode, gchandletype.pinned);     intptr pdevmode = pinneddevmode.addrofpinnedobject();     int result = documentproperties(mainwindowptr, intptr.zero, printqueue.fullname, pdevmode, pdevmode, 14);      if (result == 1)    //changes saved     {         printdialog.printticket = ptc.convertdevmodetoprintticket(mydevmode);     }      pinneddevmode.free(); }

the printer preferences window shows has "ok" button , no "apply" button. when "ok" clicked changes not saved returned application.

but if printer preferences window shown via windows "devices , printers" folder has "apply" button , changes saved permanently on clicking "apply" or "ok" button.

what want save changes permanently latter window does. how open window permanent save functionality or save settings manually through c# code?

Is there a better way to structure post methods in Class Based Views -

i'm using class based views in django , never specify url in ajax calls , omit action parameter in form because know these requests go through post method of class based view. notice view - profile page make many requests depending on user updating on page - post method become convoluted , if/else mess example: def post(self, request, *args, **kwargs): # handle user changing available date if request.post.get('availabledate') != none: self.updateavailabledate(request) return jsonresponse({'result':'success'}) if request.post.get('newprojectname') != none: creative_user = creativeuserprofile.objects.get(id = request.user.id) project = project.create_project(creative_user, request.post['newprojectname']) project.save() return jsonresponse({'projectid': project.id }) if request.post.get('projectimage') != none , request.files['file']: proj...

performance - Why is XCHG reg, reg a 3 micro-op instruction on modern Intel architectures? -

i'm doing micro-optimization on performance critical part of code , came across sequence of instructions (in at&t syntax): add %rax, %rbx mov %rdx, %rax mov %rbx, %rdx i thought had use case xchg allow me shave instruction , write: add %rbx, %rax xchg %rax, %rdx however, dimay found agner fog's instruction tables , xchg 3 micro-op instruction 2 cycle latency on sandy bridge, ivy bridge, broadwell, haswell , skylake. 3 whole micro-ops , 2 cycles of latency! 3 micro-ops throws off 4-1-1-1 cadence , 2 cycle latency makes worse original in best case since last 2 instructions in original might execute in parallel. now... cpu might breaking instruction micro-ops equivalent to: mov %rax, %tmp mov %rdx, %rax mov %tmp, %rdx where tmp anonymous internal register , suppose last 2 micro-ops run in parallel latency 2 cycles. given register renaming occurs on these micro-architectures, though, doesn't make sense me done way. why wouldn't register renamer ...
