c# - Execute a cmd file from IIS8 -


i have piece of code generates excel inbuilt functions 

string xmlfilepath = "c:\\test\\standard_xml.xml"; string script = "c:\\test\\script.vbs";  string template = "template";  string cmdfilepath = @"c:\\test\\executable.cmd"; if (file.exists(cmdfilepath))   {     file.delete(cmdfilepath);   }   using (filestream fs = file.create(cmdfilepath))    {      byte[] info = new utf8encoding(true).getbytes("\"" + script + "\"" + " " +         "\"" + template + "\"" + " \"" + xmlfilepath + "\"");      fs.write(info, 0, info.length);    }      var process = process.start(cmdfilepath);     process.waitforexit();

this codes generates excel , required operations.

this works pretty fine when testing in visual studio, when run on iis8 never works. have tried various solutions mentioned on web nothing worked.

any appreciated.

without knowing sure (through error logs, eventvwr screenshots), guess you're running permissions issue.

when executing file-based operations iis, need keep in mind apppool identity being used website. apppool identity need have write permissions specific folder.

i suggest leaving apppool user identity built-in "applicationpoolidentity", secure option.

there lots of information on subject on msdn: https://docs.microsoft.com/en-us/iis/manage/configuring-security/application-pool-identities

specifically @ securing resources part how add file permissions: https://docs.microsoft.com/en-us/iis/manage/configuring-security/application-pool-identities#securing-resources

there other scenarios can override user account given apppool, , on website (for things impersonation, etc), if not doing those, above should work.

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

jquery - Responsive Navbar with Sub Navbar -

good day, forgive me nav vocabulary not best. if question confusing apologize. i'm working on navigation bar needs centered on page @ 768px , above. items in nav open (or perhaps toggle) subnav lives directly below. these nav should appear centered on page. i have been able work through responsive portion of nav bar, having main items align vertically , sub nav menu of each item roll out below, , gave them indent separation. working well. however, issue not responsive side, behavior @ width greater 768px. happens toggling menu's sub navigation pushes other main items down page below sub nav. here's code: $(document).ready(function () { //stick in fixed 100% height behind navbar don't wrap $('#slide-nav.navbar-inverse').after($('<div class="inverse" id="navbar-height-col"></div>')); $('#slide-nav.navbar-default').after($('<div id="navbar-height-col"></d
