c++ - Looks like COM object is created, but JScript fails to get a reference -

-

i'm using following code create com component have developed , registered.

var mycom = new activexobject("mirabilis.componentservices.1");  mycom.setfirstnumber(5); mycom.setsecondnumber(3);

the first line runs fine, while if alter progid (that is, string passed activexobject) message automation server can't create object. suggests @ least basics of registration mechanism working properly.

i integrated logging calls dll. when run script proof log file both call queryinterface:

stdapi dllgetclassobject(     const clsid &clsid,     const iid &iid,     void **ppv) {     ...         caddfactory *paddfact = new caddfactory;         ...         hresult hr = paddfact->queryinterface(iid, ppv);          if (hr == s_ok)             writetologfile("class queryinterface returned s_ok");         else             writetologfile("class queryinterface failed");          return hr;     ... }

and one:

hresult __stdcall caddfactory::createinstance(     iunknown *punknownouter,     const iid &iid,     void **ppv) {     ...         caddobj *pobject = new caddobj;         ...         hresult hr = pobject->queryinterface(iid, ppv);          if (hr == s_ok)             writetologfile("object queryinterface returned s_ok");         else             writetologfile("object queryinterface failed");          return hr;     ... }

return s_ok. however, when jscript gets line 3 of script, following error message:

'mycom' null or not object

why happening? looks jscript should able obtain reference.

some attempts made

  • i tried return s_false dllcanunloadnow sure dll not unloaded, in case, no luck.

update

i should review com/ole/activex theory... adding logging calls found out jscript able reference com object, , makes total of 6 queryinterface calls it, , all fail. among these there attempt retrieve idispatch, mandatory objects used scripting languages. think implementing idispatch need make work?

asp.net mvc - breakpoint on javascript in CSHTML? -

-
i have .cshtml file has javascript tag. within script tag have few lines of javascript. first line of javascript refers property in @viewbag. other javascript lines plain script without mvc related references. observation: can place breakpoints (visual studio 2015) on each of these javascript lines. however, breakpoints has white dot in center of breakpoint symbol (red circle) except line @viewbag reference (this particular line not have white dot in center). it seems breakpoint without white dot hit during run-time. question: can explain going on here? white dot mean? why plain red breakpoint line line hitting breakpoint? the visual studio debugger expecting debug actual server-side code within .cshtml file opposed client-side javascript within it. iirc, visual studio allow debug javascript code expected in internet explorer (and possibly edge), other browsers want use either third-party tool or developer tools (f12) within browser. an easy approach take advant...
