How to set the current record in a Microsoft Access form from external program -


the background: charity work has 2 systems, new c# system , ms access system. taking phone call means looking them on new system, looking them second time on legacy system. unfortunately we're stuck access system, because don't have money re-develop it.

both systems use unique personid each person, , ids synchronised between systems. access system 1 giant form shows info particular personid.

the problem: want tell access move current record particular personid external c# program. i don't want launch new access window, slow on our pcs.

i've tried think google control access outside (something dde??) i'm drawing blank. can give me pointers for? possible?

you can use com automation. if new system e.g. excel, use vba code this:

sub testcomtoaccess()      ' has references microsoft access object library & microsoft dao 3.6 object library      dim oaccess access.application     dim oform access.form     dim rs dao.recordset      ' assumes 1 instance of access running, old application     set oaccess = getobject(, "access.application")     set oform = oaccess.forms("your_giant_form")      ' find record looking     set rs = oform.recordsetclone     rs.findfirst "myprimarykey = 42"     ' , navigate form record     if not rs.nomatch         oform.bookmark = rs.bookmark     end if     rs.close  end sub

and according how interact programs ole automation in c#? adapted c# , .net.

for c# windows forms application, equivalent code be:

using system; using system.windows.forms;  namespace comautowindowsformsapp {     public partial class mycsharpform : form     {         microsoft.office.interop.access.application accapp;         public mycsharpform()         {             initializecomponent();         }          private void mycsharpform_load(object sender, eventargs e)         {             accapp =                  (microsoft.office.interop.access.application)                  system.runtime.interopservices.marshal.getactiveobject("access.application");         }          private void button1_click(object sender, eventargs e)         {             microsoft.office.interop.access.form accform = accapp.forms["your_giant_form"];             microsoft.office.interop.access.dao.recordset accrs = accform.recordsetclone;             accrs.findfirst("myprimarykey = 42");             if (!accrs.nomatch)             {                 accform.bookmark = accrs.get_bookmark();             }             accrs.close();         }     } }

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
